Loss of Signal since the last 2 updates. - AT&T Samsung Galaxy Note 8 Questions & Answers

When I first received the Oreo update, my note had the best signal that I've experienced since I owned it (since launch).
The last 2 updates, including the security update that I received today, has resulted it lower signal. Not just in visible bars or sim status dbm, but in people stating that I cut out sometimes.
I don't live in a highly congested area, but I do live near Grand Rapids, Mi.
Anyone else experience the loss in signal?

The update today caused mine to go down some while I'm at home. I haven't had a chance to check in different areas yet. On the previous build, I had a full signal at home, which I had never had on any other build. Now, today, it's dropped to 2-3 bars. If it doesn't get better, I may go back to the previous one. I don't get what changed if it's only supposed to be a security update.

I'm running into the same issue as you. a previous build gave me pretty much full signal in my apartment. Any updates after the initial Oreo tanked my signal. Never thought about going back to the initial Oreo build. I guess I can always do that.

Well, an update since I posted that a few minutes ago. I just rebooted my phone and now the signal is full. Hmmm. I got the update today about 4 hours ago. I didn't see what the signal was right then, but I did power down and go to recovery and clear cache.
I suppose I'll see what happens now. I'll let you know if I drop at all now after the reboot.

Also, you won't be able to go back to Nougat or the first released Oreo OTA because of the difference in bootloader, as far as I know. If you took the update today as I did, we'll only be able to go back one build (I believe 4CRD7?)

JB update and signal strength

Has anyone noticed and signal strength increase with the JB update?

I was still using an ICS modem, just updated to the newes JBt and saw a - 5 to 8 db. I'll take it. Just my experience. Your mileage may vary.
You really need to let a phone settle for a while. I changed a modem and ran several netwrok benchmarks before and after. Immediately followng the update, my data speed was horrible. 30 minutes later it was great.. back to where it was previously. These were all take at the same place sitting on my desk at work.

[Q] Reception issues?

Unlike some people I've always had pretty good reception on my S3 where I live near Chicago. I had been running "Jelly Beans Build 4" for several weeks with no problems (using K1 Modem and Stock Kernel). Then last week I updated to the new Beans build, Build 6 and installed the K3 Modem and RPM (running LeanKernel). Ever since doing that, my reception has gone from always around 4 bars to usually hovering around 1-2 (happens both when I'm at home, and at work in the city and has been pretty consistent). I tried going back to the K1 modems and it didn't change anything (ended up trying all the JB modems with no differing results). I've also tried flashing the stock kernel again. No matter what I do, my reception doesn't seem to change and I can't get it back to where it used to be. Is there anything else I can try? I'm about to flash back to another ROM to see if that changes anything. Any ideas would be great though. Thanks guys.
Maybe check to see if your prl version is up to date. Do this by going to settings about phone them status. Should be 15154. If that is good no modems work and previous roms are no success then maybe they are doing work on some towers in your area. That happened to a coworker of mine on sprint and once they were finished everything went back to normal maybe even better but it took about a week of him pulling out his hair. (he is bald now). hope this helps and good luck.

Thanks for the advice; yeah I checked, the PRL is up to date as well. And flashing back to another build didn't make any difference. So I'm beginning to think maybe you're right, maybe they are doing construction or something.

Nexus 5 Radio problem, not picking signal at random time.

Hey,
Sometimes my Nexus shows there is no cell/range coverage in your area but when I search for network and register on my network, cell/signal come back to full, this happens randomly most likely in night, it's getting on my nerves. I'm running on Kitkat 4.4.2 stock rom and kernal and I've had no problems in 4.4.
Anybody else get this problem ? or any ideas to get rid of this other than flash to Kitkat 4.4.
I'm from India and using Vodafone network.

Welcome to the club
seems to be software related. cm 11 seams to fiy it, but i never tried myself. same here in germany. d821, cataclysm 4.2.2, modem .15 and t-mobile. i tried each modem but the (old) .15 one give me the best results.
btw with cataclysm and bricked kernel with undervolting i have 6-7 hours screen on time. i dont think the battery is not good enough...
It should come out of the box stock with that battery without roms or kernels.
Idk why ppl complain about the nexus battery so much maybe they need to put their phone away for two seconds so they could save some battery

If they did that people like dicecuber wouldn't have anything to complain about on the xda forums especially when they have to make a signature about the nexus 5 battery.

That's how mine is with this issue. I only have signal now at home and random parts throughout town. At my job, which is just about 5 miles away, I went from having full bars H+ (T-Mobile) to having no data at all. I swapped my SIM into my co-workers phone, I get signal just as I did with all my previous phones. I used to have great signal at work until the issue arose. I ordered a Note 3 to not have to deal with this anymore. It was great while it lasted.

In all seriousness, have you tried different radios? I mean, like flashing the radio.img from the 4.4, 4.4.1 and 4.4.2 releases? Apparently the 4.4.1 radio wasn't as good as the original so I've stuck with the KRT16 radio the whole time while I'm on Omni 4.4.2.

I flashed every radio in the modem thread, flashed back to stock and installed the OTA updates, and I still have no data except for home and random places while driving.

I wouldn't feel the need to log in to find a solution. I'd definitely be not be posting on this board. Blame google
Same problem here in Austria. Running my N5 with Purity (KitKat 4.4.1) on elementalX kernel.
Too bad. Otherwise, the phone is great.
Well i get full bars coverage at home and everywhere i go in the south of the Netherlands. I thought the N5 radio is much better than the ones of the N4 which we`re weaker for me. Stock and not rooted.
The radio quality of my N5 actually IS very good. It is just sometimes for a few seconds, that there i no signal at all. After 10 seconds, there is full radio again.

Is it so hard to understand? 99,9 % of the time, I have better radio reception with the N5 than with all my previous devices. But sometimes, about twice a day, there is no radio reception at all for some seconds, which is annoying and I hope to find a solution for that, as I am pretty sure that it is software related. I hope this was understandable now.

OPO issues connecting to phone network

Hi everyone
Not quite sure where to start so I will go from the beginning.
I purchased a OPO almost 18 months ago now and since I received the phone I rooted it and originally flashed OxygenOS but found that that ROM drained my battery in hours, so then I installed Cyanogen OS 12.0(-YNG1TAS213) and found that almost everything worked perfectly. After a while I noticed that whenever I was in the car and went through an area that didn't have any carrier service I would need to reboot my phone in order to get my data to work again. I have put up with this because it hasn't been that much of an issue to me. (I mention this because it might be related to the issue I am facing now)
In the last couple of days my phone has gone from working fine to hardly working at all, until yesterday my phone just wouldn't connect to my carrier network at all and I kept getting a message come up as a notification saying 'Selected network (3 UK) unavailable'. When this happened I tried rebooting the phone, aeroplane mode off and on, clearing Cache and Dalvik Cache in TWRP and nothing helped. Yesterday evening after backing up my important data on the phone I went back into TWRP and did a factory reset.
After switching my phone back on again and setting it up as a new device I can now connect to my network, sort of. I don't get anything better than the shaded signal icon (worst signal strength), if I move around my house for example I lose service and if I go back to the same spot where I did have signal and flick aeroplane mode off and on again, probably about 40% of the time I get signal again.
A friend of mine is pretty good with this sort of stuff and has sorted previous phones for me but he lives 200+ miles away and can't really help. He thinks however that its likely to be the modem. I don't really know what to do so if someone can help instruct me as to how I can update the modem or suggest so other fix that would be awesome.
Thanks in advance.

Try flashing a new modem. There's a thread on it. There is no best modem, what works for you may not work at all for others, grab a couple, try one per day till you find one for you.
This always fixed that for me

Sorry I am completely new to dealing with modems. This may sound like a dumb question but does any modem work on any phone and its performance is based on what network you're using?

Nope modems are phone specific. You need a OnePlus modem.
Performance can vary based on location and carrier. You're best off trying a few, then remembering which is best for your. Modems aren't rom dependant, any OnePlus modem should work with any OnePlus rom. Some are made for different versions of Android though, I usually start with the most recent and work back.
Start here:

Edit: this might have been part of the reason oxygen drained your battery too. If you've got the wrong modem your phone spend all day trying to negotiate a mobile connection. This kills your battery.

April build it already out.... no, it is not an April fools joke...

Build PQ1A.190105.045
I'm on Sprint, and never got the March update. It is letting me download the April update
Sent from my PH-1 using Tapatalk
Didn't believe at first lol had to check thx.
If you look at Essential's builds page you'll notice that there is not a Sprint version of the March update. I suspect that Sprint would not approve / accept / allow the updates. I'm hopeful that the April update will fix the Bluetooth issues introduced by the Jan or Feb update. I've also experienced significant loss of signal strength since the Jan and Feb updates, which I believe are tied to the modem security patches in those updates, and I'm hoping April fixes that as well. If not, I'll be downgrading back to December's update. I have LITERALLY gone from "bulletproof" data connections all over my City to routinely losing data connection, and my average speeds at home and work have dropped significantly. I know it's the build and not the network because I have another PH1 on Sprint that has none of these issues after being downgraded to the last Oreo build...
Edited to add: The April update is taking much longer to install than the monthly updates normally do. It took over 30 minutes to complete the app upgrade process today. Fingers crossed that this means there are some big fixes under the hood.
---------- Post added at 09:38 PM ---------- Previous post was at 08:45 PM ----------
Uodate: after installing the April update and rebooting once to get a fully "clean slate", I ran Speedtest... WOW!
So, good news and bad news for me, and likely anyone on Sprint. When I ran speed tests last Friday (same app, same location, same phone, on the February Pie update) I was getting download speeds of about 12mbps and upload speeds of about 10mbps on average. After the April uppdate I am now getting download speeds averaging around 75 to 80 Mbps (!!!!!!!!!), but my upload speeds have dropped to an average of about 2.5mbps....
So, whatever the April update contained has helped and hurt. Now, to see if it has fixed my intermittent Bluetooth problems... Fingers crossed.
The speed test at the very bottom was last Friday. Everything else above it is today, after installing the April update.
Yes, upgrade (74MB) installed & working, but took forever to optimise the apps, I was sweating a little since I'm in Australia & can't send phone back to Essential if major issue.
Update includes improvements to minimum brightness & volume which is good ... especially if you like to use your phone in the middle of the night without waking your beloved! ?
Note that for Sprint users the file size (if received OTA) is about 96mb (approx, my recollection may be slightly off). My wife's is on AT&T and I noticed the size difference when updating her phone. Hers also seemed to optimize apps a lot faster than my Sprint PH1. It would appear that Sprint bundled something else in with the update (BT / modem fixes? March's Android security patches that we missed? Who knows...)

Can't shutdown with April '19 update
When I tried to shut the phone off to swap SIMs with my other phone, the PH-1 got to the part where it bumps the vibrator and hung vibrating for 2-3 seconds and then re-booted. Argh! Bluetooth is still borked... I have to shut off Bluetooth and restart before my Jabra 65t's will connect and even then it's iffy.
That's weird. No shutdown problems like that with mine. I've not noticed any Bluetooth problems either yet (but don't really know what I'm looking for with that, last build seemed to work OK for me too, I only use Bluetooth for pairing headphones)
And as usual I still don't have any of these weird problems. Oh well maybe the next one.
I had to go back to the original slot.
The new update breaks WiFi and data.

It's stock but rooted with Magisk (no TWRP), just happened since Jan update, it was ok last year.
Someone said it's hardware related, maybe true....but if I go back either Oreo or early Pie then no problem.
The max volume is quiter than before..
Anyone else has this issue?

Any time you have an issue and are rooted and running apps or software that fettles things I would say the best test of is it software or hardware is to flash back to stock unrooted and see what's what.

Thanks for your suggestion, unfortunately, I did flash back to stock without rooting, and still had no LED notification.
To be honest, it only shows up one time after fresh stock ROM flash, and never show up again.
There's no LED notification when missing phone call, SMS/MMS, but......the LED is blink ONLY when I have voice mail waiting....that's pull my hair off.
