Sim card and battery drain

Not sure if this has any real correlation but I figure I'd share. Long story short, I had been getting horrible battery life all day at work. Phone wouldn't even charge. After work went to T-Mobile store and had a new sim card placed in the phone and instantly the battery drain disappeared.
I was using the battery widget and noticed drain as much as -750mA. Soon as the new card, -2mA. I had restarted the phone several times already and it never drained this slowly. Only after the new card. Just thought I'd share.

I might give this a try as well. I got 9 hours today with moderate use. Just web surfing and texting, and about 10 minutes of streaming radio, actually.
I need to know the cause since I only have another 7 days to take it back.
(And yes, I know the battery level readings are messed up, but there's no messing up the fact it was on the charger all night, and then I went from 100% to 1% in 9 hours.)

Interesting. I just used my old sim from my g1. Time to rye three new sim then.
Thanks for the notice!

Here is the visual evidence. This is with the phone on the charger. You see many times that it wasn't even charging and at times discharging. The huge green line is after the new sim.

It's a brand new 4g network doesn't it make sense to get a fresh sim, especially if this is your frist 4g phone.
The sales chick.... wait a second that's a new term "sales chick"
Well the sales chick specifically told me she needed to give me a fresh sim so I would not have any problems with reception.

If I pop in the new sim card will my phone number transfer automatically? I know in europe the phone numbers are locked to the sim card.

I'm going to do that tomorrow then, i have my sim from my blackberry 9700 then to hd2-g2-now the g2x. I believe i don't have the "4g" sim-card then.

there is no "4g" sim card
there are only newer sims and older sims. older sims have trouble connecting to some of the newer towers, usually if they are over 1 1/2-2yrs old you should probably get it switched out for a newer style. most stores should do this for free.

Those swings in reported battery are most definitely from misreporting drivers.
...and swapping the sim card you pulled the battery, which also helps to throw things out of whack.
I dont see any correlation to sim card and battery life in this instance...you just happened to be swapping a sim at the time.

FWIW, it really could be the SIM. I had a similar problem with my Nexus One - high battery drain and inability to hold a 3g signal in a solid 3g zone. T-Mobile suggested a SIM swap, which I thought would do nothing. Wrong. 3g signal locked and stayed locked and battery drain came back to normal, probably because the phone wasn't constantly seeking for 3g.
That SIM failed, BTW. Used to hold 3g well and then it stopped.

I changed my sim and i dont really see a big difference. Ill give it a few days.

Try setting your phone to WCDMA Only so it doesn't keep seeking between 2g/4g (this really sounds like the N1 bug)

As a T-Mobile employee I can tell you that you need a new sim in all of the 4G phones G2X, MyTouch, G2, and Galaxy 4G. your experience with the new HSPA network will be directly affected with these phones and the old 2G sims, guaranteed. It only makes sense that when the new network was implimented that a new sim would be part of this puzzle. The sim is your only connection to the network, so I'm totally perplexed as to why this is even in question. The reason you are seeing such high battery drain rates is because the old sim is not connecting to the network properly. I change out customer sim cards all day long. The new sim cards are designated with a TM9073 on the back of the card if you are questioning what kind of card you have. Everyone at my store is well aware of this and whenever a 4G phone is sold a sim swap is performed to make sure of a good experience. Now to complicate things there are some bad sims floating around that are 3G/4G sim cards, best way to descibe them is that the cell on the back of the card is faded looking in either a very small square or very large one. If you have a "good" 3G/4G sim the size of the cell will be in between these two sizes and it will be well defined and not look faded. if you have been with T-Mobile longer then 2-3 months you may need a sim swap which is free as long as you are not replacing a lost or stolen sim in which case the cost is $19.99. If you have been a customer for two years or more you Definately need a new sim with a 3G/4G phone. T-Mobile has released very little info about this and even a lot of the new phones still are prepackaged with the not so good sims. If the people working at your local Authorized T-Mobile Retailer don't know this I'm not surprised. Do yourself a favor, before you fly the handle about bad battery life or poor reception with this phone check your sim and if need be swap it for a new one, it's free. Hopefully this helps

My G2X came prepackaged with the 4G TM9073 and still had battery drain issues, resets and lockups.
Has anyone received a different sim than this with their G2X?
For all the users that followed the proper protocol and used the sim that came with the phone I dont see this as being the issue for battery drain problems. It has been documented that there are several software issues related to battery drivers, and possibly even a hardware issue with charging via wall adapter.
While on the topic of sims though...DO NOT touch the contacts on the sim, leaving oils and fingerprints on it can cause issues...have seen it several times as an issue in projects I have worked on manufacturing embedded devices.

[Q] NS4G Nexus S 4g, very poor signal, seeking advice

Hello all,
I just received my new Nexus S 4G for Sprint yesterday (5/14) and I love the phone, but I have just awful service on my phone.
I live in Princeton, NJ, which is a town notorious for not having the best service (for all providers) to begin with, but compared to my Epic4G that I came from, there is definitely something wrong with service for my NS4G. Note: there is no 4G here, so I cannot test that.
There are not much discussion of poor signal for the NS4G here on XDA, but there are numerous reports from people having similar problems elsewhere, i.e. http://community.sprint.com/baw/thread/67927?start=0&tstart=10
I will describe my problem...
Calls and texts, MMS, works just fine... however, my 3G service is abysmal. Running speedtest.net, half of the time I pull in 30-40 KB/s, occasionally (maybe 1 out of a dozen times) I can pull in 40-80 KB/s. The other half of the time, either speedtest refuses to run because of network problems, or I literally pull in 3-6 KB/s. My browsing experience is horrendous, almost useless, downloading apps from the market is a 20 minute ordeal.
I have been able to connect to a WiFi network, and everything seems OK from that standpoint.
My fellow XDA users, I seek advice from you all...
I know that the NS4G is brand new to the Sprint network, and is the first CDMA nexus phone. I know that other phones have launched with similar problems, and they usually receive fixes relatively soon...?
Do you think I should try swapping my NS4G for a different one? In my opinion, I think if I swapped the NS4G, I would just have a different phone with the same problems.
Should I wait 30 days and see if service improves by then?
Anyone with similar experience? Suggestions? Switch back to Epic4G and wait it out (noooooo! )?
Thanks

I'm having the same problems, except I'm pulling slightly higher speeds than you. I've talked to sprint and they got a tech to come check out my towers and they'll let me know by monday if its a tower problem, or if it's just slow speeds in my area (its not my phone as i'm able to pick up normal speeds in other areas). I'm giving sprint a week or two to clear this up or else i'm taking the phone back within the 30 days.
also, did you try updating your prl/profile? it's unlikely that it'll help, but worth a shot.

I get around 3mbps on 3G
And around 5-6 and sometimes 7 mbps on 4g
Som im clearly not having this issue, but i will go roaming after the phone falls asleep for a while.

same problem
Im having the same problem I only had the phone 12 hrs I thought mayb it was da tower den I did a speed test between my epic n the ns4g n the epic blows it out the water not on da speed test app but in real life testin like pullin up web pages

The signal is weird. Signal strength at work on my Epic was 5-6 bars. Nexus S 4G is 1-2 bars. Signal strength is between -76 and -92. I forget what my Epic was pulling in actual numbers strength wise. Speed is the same awful crap though on 3G.

I've had two Nexus S devices on Sprint and they both exhibit the same weak wireless reception. In real life I would say the differences are minor or insignificant but I was hoping for better or at least same radio reception as my almost 3 year old HTC Hero and clearly that isn't the case. Hopefully Sprint can rectify this in the future with some sort of update since I'm not aware of T-Mobile users having similar problems which would indicate an actual hardware flaw(?).

I'm almost sure its a sprint side issue. I left sprint for 3 months and came back and I've had an epic, evo, and nexus exhibit the same behavior. Before I left sprint I had zero issues and I've owned all of their smartphones and one point or another. It just seems like its slower in certain areas though.

try updating PRL

Since our phones don't accept network pushed updates you're going to have to do a manual prl update. If that hasn't been done your service will suffer. That should help a bit.
Sent from my Nexus S 4G using XDA Premium App

I've tried all the tricks, updated profile, PRL, reactivated my phone, etc.
Nothing is working...,
I've also noticed (completely unrelated issue) that my earpiece speaker crackles at any volume; its subtle but very annoying.

This seems to be an issue for people with the nexus. My old phone had full bars whereas with the nexus I'm only getting 1 or 2 bars on 3g. Seems to be an issue with their towers or Google. Its an issue with their network and not the phone. I spoke to sprint earlier today and they said they are aware and working to resolve this. So they say if course..

Update (end of day 2):
For the last 5 - 6 hours I have been receiving moderate to adequate 3G service, albeit pretty inconsistent.
I now average 70-120 KB/s, and rarely drop below the lower 70s. This is more on par with what I was getting with my Epic4G for the last 6 months, always pulling in around 120-170 KB/s pretty consistently.
I've run 240 speedtest.net tests today, lol.
I hope it never goes back to how bad it was yesterday and this morning.
Time will tell, -- I'll let you know what happens.
I spent a good deal on the phone today with Sprint, 1 out of the 3 people I spoke to said that spotty reception on the NS4G was a known problem and engineers were at work fixing it. The others had no idea what I was talking about. I don't know what to believe.

Awww man you gotta be kidding me... I already get awful speeds with my Evo and now it's even worse with the Nexus 4g... the phone i'm planning on getting?!?!? this sucks =/

Anyone else's uploads constantly double or sometimes triple that of their download?
My last 5 3G speedtests in kbps
182/325
307/488
99/469
47/169
59/152
There is something seriously wacky with the way the radio is acting.

Update (Morning of day 3):
Everything is back to crap again this morning. FML, lol
Edit:
Each speedtest.net test keeps returning downloads between 5 - 15 KB/s

I'm getting crap 3g speeds as well, up and down

Ditto. 3G reception at least 30% weaker than my Evo. Side note, my battery life has been crap too, I wonder if the phone is using more power trying to hold the signal?

I spent a little over an hour on the phone with sprint yesterday for this same issue. They trouble shot my phone, prl updates, network refreshes, nothing worked. They told me I had a defective unit and to exchange it. I went to best buy and the rep had an evo. He had full bars in the store, his dBm was -76 or whatever, it was in the 70's. Mine had 0-1 bars and a dBm of -96. He activated my new phone and checked it, same exact thing. He got sprint on the phone and they made him go through all the same bs prl updates and stuff. After a half hour, they told him they were looking into the issue.
Ive seen alot of people say its AOSP that causes the poor reception, and that is true to an extent. The EVO running CM does not get the same as sense roms. I live in a basement apartment, I know. On sense, my evo sent an mms message almost instantly. On CM, it wouldnt send them at all and it dropped calls like nobodies business.
When it comes down to it though, the radio on the Nexus 4G is just not performing well. I hope there will be some sort of update from google or sprint to address this in the very near future, or I will have left Verizon and sold my Thunderbolt for no reason...

I hope this issue can be fixed with a software update. I would like to know within the 30 day return period so I can get back on an evo running cm7 if I need to.

This is getting blown out of proportion in more ways than one. YES, the Nexus S 4G does not have as great of signal reception as the EVO or Epic. This is already well known. However, just like the iPhone 4 when it came out, the AOSP version of 2.3.4 on the NS4G doesn't display signal bars properly. That's part of the problem. But when you dive down into actually how many dBm's you're getting - that's where the problem lies.
In San Francisco, I typically get 600-1000kbps on 3G and 4mbps-8mbps on 4G WiMAX. Lately, after continually attempting to update the PRL on the device and so on, I've gotten results like the one below. This is on 3G in Daly City, CA just outside SF.

On my second S3, and its also broken...

How many of you have had to return your S3 due to out of box defects? My first one would chronically overheat, had low signal, miserable 3g speeds (I know they're pretty miserable anyway), awful battery life, and would consistently drop my wifi signal at home.
Now, I'm on my second device. This one doesn't hold a much better signal, and worse yet, I have a very random screen glitch where it shows digital artifacts on some screens, and sometimes it actually flashes and randomly blinks at me, very much like a PC with a bad graphics card. Unfortunately it doesn't do I consistently either.
Am I just the luckiest person alive to get two of these that are bad straight out of the box?
I feel like a dbag taking this one back after I already took the first one back with issues. Especially since the graphics thing is so intermittent.

Sorry to hear that man. The only issue mine has is with very dark Grey screens it shows small black splotches on the screen, otherwise never there and I've looked closely
Otherwise 3G is slow (200kbps or so) but bearable. No other major issues, battery holds a 6.5hr charge with constant use and screen on basically non stop stock battery

On my second one, the first one had a Bluetooth issue. When connected to any BT device it would crackle randomly. The second one had issues out of the box. Same as you, connection was horrible. Even in the same locations and apps, the first one seemed to connect well. I ended up doing several factory resets and now it seems better. My local vzw store was convinced enough to give me a third, but after it settled down I figured that I'd just keep this one. There is something weird about these phones. The connection is worse than my thunderbolt. The battery is all over the place (due to the radio I'm sure). We'll see I guess

I have a blue 16gb and wife has a white 16gb, both arrived early on pre-order. No issues with either phone.

Yeah, it sucks for sure, he phone has so much potential if it worked properly.
I dumped att for Verizon at the same time, and my 14/days are up today. Ill likely port back to att, and wait to see what happens with LTE here.
3G alone is just unbearable on VZ.

This is something to do with the phone, not verizon. I said in another thread they need to fix these cell issues asap. My old phone got 3 MBs down and up, this one gets less then 1 on both. 4G is fine but I don't live in 4G area, unless I literally walk a street away...:silly: Start calling and reporting this stuff to customer service. I've been doing this everyday.
Complaining on a forum does not fix the issues.

My first one had the USB port randomly go bad. Returned it in the first 14 days. This second unit is working ok though there seems to be a spec of dust or something under the screen that drives me slightly insane.

Radios have not been samsungs strong points. Wifi essentially does not work until I turn off power save which is a pita and resets after reboot. My rezound never had issues even with wifi on power save

Samsung radios have always sucked, Samsung is known for this.
My Rezound had a far better radio than either my current G3 or my Wifes Droid Charge (& the POS Nexus I had briefly was even worse).

Calling customer service doesn't fix "service" issues either, not to mention I don't have time to be on the phone with CS telling them how my service sucks every day. Not to mention that my gf can have full service, the Xoom has full service, and this phone has 3 bars if lucky, along with abysmal download speeds. Its as bad as Sprint with this phone. This doesn't seem to be Verizon isolated either, as local US Cellular customers have also been complaining of slow speeds and bad reception.
I don't even know what else Verizon has that I'd consider. Just sucks, because the phone is very nice.

i returned my gs3 suposedly due to factory defect but i knew it was my fault, and it had 3 dents on it from me dropping it lol... after flashing roms with k-exec so many times, i managed to change the network type to 3g only and the best buy rep couldn't figure out how to get it to connect to 4g. I know how i could of fixed it with phone info from android market but thats after the fact.... So he replaced with a brand new pebble blue 16g gs3 and it was updated to vrlg1 rather the older version. I was greatfull plus i added black tie protection and purchased buy back before they ended the program :fingers-crossed::good:

I am still not convinced this is the case. I also have a rezound. They report the signal differently and what I've noticed is that it seems like the Samsung phone because of the way it reports the signal assumes the signal is worse before the rezound does and kicks to 3G sooner.
I don't know if it can be changed so it holds 4G longer, but back when I had an evo 4G with wimax you could tell the phone to hold the signal longer than default and I'd get wimax in my house when default settings would kick me immediately to 3G when I walked through the front door.
So I don't think the phone has terrible radios just that if you rated the 4G signal on a scale of 1-20 with 20 being the worst reception, that the rezound will hold 4G until it hits 18-19 and switch to 3G and the GSIII cuts out at 12-13 and there for where I have signal with my rezound, I could have it with the GSIII, other than it decides to dump the signal.

was never called black tie, it was Geeksquad Black Tie protection, Which if you are part of the actual Geeksquad culture, made perfect sense. It just doesn't relate well to your average person.
Also, Buyback is still a plausable rip off. If you are lazy, then it makes sense to get it. I will use my rezound as an example though. Best Buy has the phone in the system for 650. In the first six months I would get back 325 back. If you held the phone like I did for 9 months, you'd get 40% of the phone back, so 260 dollars. Not counting that after 10 months it is 30%. If I sold my phone on swappa, ebay, what have you, including my extended battery, I could get about that much, or more, without having to pay an initial fee to get the ability to get that money back.
Also, people are stupid, and phones that are already s-off, and with a rooted rom sell for more money. Best buy doesn't trade in the extended battery, and it being s-off'd would kill its value, if the tech doing the trade in even knew how to check for that.

My S3 was working great until this week (right after the 14 days return window). Now WiFi is dropping, 4G is running at worse than 3G speeds, phone randomly shuts off, apps that worked fine previously now crash / lock the phone on a black screen. I hope I can just swap this back out for my Thunderbolt without any issues. Hopefully I can get a replacement on this. If the 2nd one has these issues, I'll go back to my Thunderbolt which has been rock-solid since I got it.

My first phone was a pre order phone. For the lifebof me and Samsung and Verizon. We could not get the flipping GPS to find the phone. Both Verizon and Samsung tried to tell me that the phone needs the celular network to use GPS. I had to tell them that that is either impossible or that the phone is falsely advertising stand alone GPS. And if Samsung and Verizon allowed that to be that some one is in for a legal ride. I told them that I would never purchase a phone or any mobile communicqtion device without that option. Long story short they sent me a new one. And everything works perfectly. Well, with the exception of it freezing on me at times. This could be due to an over heating issue or just bad designe in the software. Though it has not happened in a while since I have frozen some of the Verizon and Samsung crap bloat. Specifficly Verizon. They know how to screw a good thing up. Also, I have this thing underclocked at 918MHz-1.134GHz. This helps a great deal because of wifi teather and bluetooth on in my car all day long. Now to find a charger that will let it more than just charge at a snails pace.

Nexus 5 GPS issues?

Is anyone else else having issues with their GPS? I'm running stocked rooted and it takes my phone forever to get a lock from the birds. It doesn't matter if I'm inside or outside it takes 30-60 seconds for a lock which I think is ridiculous.

I fix 11/23 sats in max seconds, sometimes it fix up to 18 sats after 2/3 minutes...... Stock, without mods.. :good:

Do you have WiFi and aGPS location reporting off? It could slow down position locking.
Sometimes my Nexus 4 GPS antenna hangs though, a restart and locking on via Maps helps for some reason, I use the app GPS Stats to see how many satellites the phone's seeing, but I guess you've done that. Maybe try out a tracking SW like Locus or something and see if the phone remains locked when moving for a longer period of time like going home from work, if GPS signal constantly goes away I'd recommend contacting Google on the issue. They'll either confirm to look into it or offer a replacement.

These are that stats I'm getting with GPS status seems very off to me... I'm probably going to contact sprint about this later today or tomorrow

I'm having a problem with GPS on mine as well. I play Ingress which is a location-based game made by Niantic (owned by Google). I have a lot of experience playing this game back to January on my Nexus 4 and have also played on my Nexus 7. The Nexus 5 is slow to lock and has much greater error than the Nexus 4 as reported by GPS Status when I am holding phones side-by-side. It seems to really perform worse under non-ideal conditions (inside a car, near tall buildings, bad weather). It seems to lose lock or otherwise have greater error under those conditions especially. I have heard of people who have no apparent issues though so it could be my device is just defective.

+1 under the exact same conditions. Really pissed me off blowing through L8's and "all resonators missed" pops up when I'm on top of the goddamn thing.
I came from the Note2 and noticed that the GPS kind of acts like a kid who didn't get the tootsie roll so just acts like a lil punk and doesn't listen or do what they're told. Nothing as horrible as the old Captivate fiasco, but nowhere near other devices I've owned. I'm guessing an update or two can fix it (along with the camera and signal drop issues)
+side note+
faction and location?
Feelin' smurfy in central Florida

I also have problems with the GPS.
The satellites are really long to fix (approx 5min, even with aGPS), and the signal drop quickly.
Only way to play Ingress : wifi positioning.
It is impossible for me to use Navigation in car

same here

Is anyone else else having issues with their GPS? I'm running stocked rooted and it takes my phone forever to get a lock from the birds. It doesn't matter if I'm inside or outside it takes 30-60 seconds for a lock which I think is ridiculous.

Same problem here on pure stock, no root. In car navigation is useless. Gps status toolbox is able to make it fix for a little while but signal is lost again after a (few) minute(s). Only thing I might have done out of the ordinary is switch from dalvik to ART. Gonna revert that just to see. Will report.
Reverting tot dalvik doesn't Fix it. so as a test, unlocked bootloader and reflahed stock firmware from google page so it was pristine again. No joy, no GPS lock.

This with stock without mod.....

There are some various threads also on the issue. I have found that the GPS appears to improve when I applied some pressure to the area below where the camera is on the back. The GPS antena is here and there is some hypothesis that the antenna may not be secured properly resulting in the poor performance. I was able to have better results playing Ingress after doing this. Per GPS Status, performance still not as good as my N4 so will probably RMA soon. It would be interesting if some having the issue tries applying the pressure to see if there is any improvement.

Mine doesn't see catch any signals on ART.
on dalvik it works but very slow compared to a S4
A S4 locks on 11sats in 10 secs indoors.
My N5 sees 2 in the first minute then just sits there.

More info... I have a US model and I am currently in Europe.
I compared mine side by side with a european model (D821) and it locked on much faster... 10-15 seconds.
I compared the gps.conf files and they are identical.

Someone started a thread one Google's forum. I suggest everyone add their post to that list so Google can see it and address the issue.
http://productforums.google.com/forum/#!topic/nexus/EkllXr0ZlZM
I'll test applying pressure to the back of the phone later but that's obviously not a long term solution.
EDIT: Applying pressure didn't seem to help.
I was on ART and couldn't get a lock. Switched back to Dalvik and it locked right away the first time. Turned off all GPS/Wifi/etc and waited 5 minutes. Second time could not get a lock whatsoever so I did the usual wipe cache/etc and uninstalled the GPS test app and re-installed and still nothing.
Calling Google.
EDIT#2: RMA on the way. Google support could not confirm whether other users were reporting problems. Rather than wait for a software fix I'm taking my chances with a new device.

no issues for me
Locks instantly using T-Mobile in lost Vegas. Had sprint with last 2 htc's. Was always hit and miss. Sucked

I own a german bought 32GB D821 with serious gps issues too so that theory doesn't fly.

Same issue here as well. As an Ingress player, this is extremely frustrating. It loses its GPS lock way too frequently.

Try 2G Network mode on Mobile Network Settings
Actually, this problem persists since Nexus 4 with Jelly Bean jwr66y update. GPS Status app show me that my GPS got really weak signals when I'm in 3G networks, but it got really strong signals and work very well when I choose 2G network mode in 'Mobile Network Settings'. I wonder is it the some problem with you guys? If it is, then it's absolutely Android bug, not hardware issue.

Not sure I agree. My nexus 4 is rock solid with GPS on any network mode (LTE/H+/2G) and always has been. Even in areas where my signal isn't strong the GPS wouldn't ever falter.
I've posted my personal findings at http://productforums.google.com/forum/#!topic/nexus/EkllXr0ZlZM now that I have my RMA device in hand also and can do side-by-side comparisons.

screenshots from GPS Status on nexus 4
That's kinda strange. What version of Android do you installed in your N4? Here 2 screenshots of GPS Status on my N4. First, I use 3G network (as you can see on the signal bar at the top of the screen) and waited about 3 minutes outdoor under clear sky. Weak signals. Then, still standing on the same spot, I switch to 2G Network and look at those bars, and the time it needs to get fix, work perfectly.

Note 10 Plus cellular reception

Just moved on from the S9 {SM-G960U1) to the Note10 Plus (SM-N975U1) and I'm experiencing some trouble: poor cellular reception.
This is not a lack of signal bars - I know those don't tell the story - this is a COMPLETE lack of service in areas where I usually have service. Today. I brought my second line - a Samsung S8 SM-G950U1 - with me and in about 75% of the areas I travel in, there was a complete lack of cellular signal while using the Note10 Plus meanwhile the S8 was pulling down 50 or 60 Mbps. Where there was a signal on the Note10 Plus, it would pull about 3 or 4 Mbps while the S8 was sitting at 80 or 90 Mbps.
What's going on? I already reset my Network Settings and the next day had my SIM card replaced. This was based on noticing that at my house where 80+ Mbps was routine with the S8 and the replaced S9 (SM-G960U1) the Note10 Plus can hardly muster 12 Mbps, usually 2 to 3 Mbps.
AT&T, just upgraded to their top plan with unlimited everything with no data throttling and 50GB hotspot per line. On Android 12 with the most recent updates. Sitting here with ZERO bars, no signal, thankful that there is Wi-Fi available.

Try in safe mode to rule out 3rd party apps.
Clear SIM toolkit data.
Network reset and clear system cache.
Ask AT&T advanced tech support to reset the network on their side.

Cleared data, reset network settings, and started in safe mode. ZERO signal. I'll call AT&T again. I called them Monday evening and they reapportioned the card and reset the signal then yesterday i had the SIM card replaced. I'll request advanced support.

When I was first messing with the phone earlier this week, I came across a menu that had about a dozen radio buttons to select I think it was network type. I remember it had some options but the top one was Automatic and I think CLTE/????? or something was selected. I got out of there quickly but now I want to look at it to see what the options were.

Here's mine:

I see one difference.
mnc number
If you replace the sim card, do it yourself and handle it like a stick of ram. It can be damaged by ESD, at least discharge yourself to a nearby earth ground before handling. They're a dime a dozen but a failure can be inconvenient and cause a lot of trouble.

I looked into the MNC. 280 and 410 are acceptable for AT&T and it depends on the SIM card number as to which one to use. 280 is correct for mine. Can't edit it anyway. It's locked to the SIM.

This is back home:
I mean, it's better than earlier in the week but I don't sit at home all day. To be sure, I'm perfectly happy with the above numbers. Hell, I'd even be happy if they were halved while out and about.

Those aren't good either... mind you there's a cell tower half a mile from me.
Maybe take it to a Samsung Experience center at Best Buy and let them run some advanced tests on it. See if they can pinpoint it.
Or return it.

I might be prolonging the inevitable but I messed around with it some more. Can you tell me what the preferred network is shown when you look in the phone info at *#*#4636#*#*

This thing is just junk. I got T-Mobile prepaid just to see if there's a difference and there is. It's slightly better. The same dead spots are there but they're briefer and the service is sometimes faster. Side by side another phone in the T-Mobile store where you know they boost that signal and I could barely manage a third of the other phone. Now, T-Mobile limits the prepaid customer to 65% of rated but it wasn't even close. We made sure we were using the same Speedtest server and he turned off 5G data. I'm going to perform a factory reset and try agdin but that's not going to work. If it doesn't work as a phone, what good is it?

No issues on either one of my Snaps N975U/1.
Both run well on AT&T. Same sim card for over 2.5 yo.

The phone is not junk. It's a good device. It's just not working here.

Not sure what the problem is especially if you have a good signal. My guess is that device itself. I spend little more time then it took to put in the sim card to set up the connection on the newest one.

I factory reset this morning with the AT&T SIM installed. I don't want to speak too soon but at my house, the speed test results are more than 60 Mbps every time. The last five have been over 100. Still have to take it out on my travels and see if there's an actual, real difference but that seems better.

Remember to turn on/off airplane mode when traveling if it has trouble in an area to reset the tower it's using.
Try a hard reboot:
Press and hold the Volume Down button first and don’t release it.
While holding it down, press and hold the Power key.
Keep both keys held down for 10 seconds or more.

I took my S8 and the Note out Thursday morning and compared them. Both are my phones and on the same AT&T plan. The Note just has a very difficult time picking out a good signal. I spent about 5GB of mobile data running speed tests, drove over 100 miles, and walked almost four miles. Where the S8 would aggressively cycle through the bands to maintain some connectivity - be sure, there were plenty of slowdowns - the Note just camped out. RSRP numbers ran -10 or more even up to -20 lower on the Note than the S8 across the board. What I learned is that the signal is not that effective in a lot of areas around my parts but I'm not asking for that or super-fast speeds. I just need to look stuff up from time to time and stream music. Most importantly, i need to be able to use my phone as a phone. It can't even do that well. Maybe it's defective but I'm not willing to go through this again. Looking at the Xperia. Had Sony phones in the distant past and looked at them before I got the S9 a few years ago. Just started looking, not really sure what I'll do.

Something about that copy. I'm not seeing that issue with either one of the two I own. My download speed was substantially higher.
