signal strength on cm11 - Verizon Samsung Galaxy S III

Hey, i'd put this in the cm11 thread but i only have 2 posts so maybe someone else can just either copy what i say and put it there or answer me here.
There are a couple people over there that have had their phone switch back and forth from their network extender to a tower.
I don't have an extender but a guy a few houses down from me does, and when i go near his house my phone goes into roaming mode.
at my house however, since atleast cm11 m6 my signal usually hovers around -110 which is normal for me, i'm a tad far from good service.
yet it'll drop to -1 really often and with doing so cell standby under battery shows that I have like 35% with no service.
i've pulled my sim to have my prl udpated, i've set roaming to home only, and i've set the network type to cmd + lte/evdo.
i've factory reset and nothing has worked.
maybe the strength text in the status bar i'm seeing doesn't mean much and its acting normal, just seems weird since the g2 sitting next to it has constant signal strength of -107 with the same settings selected as my s3.

ok i went and sat in the verizon parking lot and had -83 dBm signal strength and it randomly still went to -1 so the fact that my house is right on the edge of coverage seems to not matter so much.
and idk if this is related but in the play store settings my device is listed with no carrier.

well i ditched cm11 for cleanrom and the issue is no longer present, so i guess its an aosp issue or something.

ok so to try and tackle my issue today I did the following:
triangle away my counter
odin to stock LG1
reprovisioned my phone with *2767*3855#
odin to BMB1 with root, unlocked bootloader, flashed recovery
factory reset / format system, flash cm11 6/8 and gapps
my signal still drops to 0dBm
i've checked my network type and its set to LTE, roaming is automatic, subscription is RUIM/SIM
so i'm assuming this is a bug with the way CM reports signal strength, once it reaches a certain number it just goes to 0 and triggers cell standby in the battery which is why i see that draining at least a quarter of my battery and displays a high time without signal
headed to a strong signal area to see what happens there and I will update this post with my results
EDIT must be my house has the worst coverage, or the phone is trying to connect to a tower on the mountain since I live right at the base of one. 1 city block north/south/west and my signal is fine and never drops out, but as soon as I pull into my driveway, it bounces from 0dBm 99asu to -110dBm 28asu every minute or so as if the signal isn't being handed off to 3g at all. Manually selecting 3g as the network type works fine so I'll just do that while i'm at home on wifi, then manually switch it to lte when needed.

Constant network issues

I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.
Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...
I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.
Go complain here in LG forum. This is software issue.

have full bars but cant download anything. just sits at waiting for data connection.
We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)
I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.
Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.

Network issue

Hi everyone
I have an issue, when I'm on my office the network signal isn't strong so when my One S go to "NO NETWORK" after it don't go back to network.
When the situation is this I can't go to airplane mode, change operator (from settings), the only thing that work is shut down and restart (no fastboot).
Anyone else have this problem?
Maybe is a software bug?
I have the Paul recovery and su
EDIT: More info
That don't happen every time that the phone go to "no network".
I think that happen when it a weak signals and are under 2G network.
there are users with similar issues, I only use 2G networks. If i want to do a bit of browsing i will manually change to auto mode, but other than that i always leave it at 2G..
hopefully there will be a radio upgrade soon that should fix this problem...
I'm suffering from the same behavior!
I'm still with the original ROM with no ROOT so I contacted HTC about it yesterday.
I got today their reply today:
"On your phone, kindly go to settings > mobile network > Network mode, kindly change the network mode and check how the signal will respond to each of them.
-Kindly try a different SIM card, to check whether the issue is with the SIM card or the phone itself.
- Soft reset for the device by pressing the power button for 10 seconds.( Note that soft reset erases any unsaved data.)
- Safe mode(which disables any 3rd party application which might be causing conflicts for your device.) for the device by Switching power on , then press and hold volume down when the quietly brilliant logo appears on your screen, you should see 'safe mode' text written on the bottom left of your home screen.
- Factory data reset, kindly backup your data before proceeding with this step please as you will
lose every data on the phone's memory.
Please go to Settings > storage > Factory data reset > Reset phone."
I haven't done anything yet and I didn't notice the 2G issue you mentioned.
I also haven't got this issue for the last 48 hours but did encountered it twice (!!!) on Sunday while driving across the country.
I'll try having the Network on 3G only and see if that matters although the area I leave in is not with good 3G reception.
GSM is 2G
WCDMA is 3G
i use GSM only unless im using the net
I'm aware to the 2G-3G difference
I'm on WCDMA preferred so my phone tries to be on 3G.
My phone also suffers from the 3G<->H data connection jumps while the desire wasn't having any with the same provider (different SIM of course).
sorry, My bad !!
i understand what your saying now
I cant confirm much as my provider doesnt have 3g signals in my area
If i try to use 3g at my home, I have 0 bars thats why i always use 2g
I switched to 3G only (since I have most of the time 3G and surly wants it for the data rate).
I know I have on my way to work and back places with 2G only but I'll give it a try for the coming days and reply.
BTW, just few minutes ago, while having 3G active for sure (before the 3G only switch when it was still on 3G preferred) I couldn't make any phone call although I had 4-5 bars and data connection was running.
Two days ago I tried to change my sim.
Before I had a cutted microsim, now an original microsim and the issue is still present.
Yesterday I had this problem only in afternoon, not in morning and only where the switch from no network -> 2G -> 3G is very very frequent.
In all other times out from office I never had this issue.
I also changed SIM with no help, stayed in 3G network only with no help and observed that when such a network crash happened, GPS reception is also disconnected!
I had no coverage situations with the 3G only mode which recovered, but what we are facing is a network "crash".
Our situation was escalated to technical support of HTC after I wrote them all the data and they tried to solve it over the emails w/o success.
Same problem for me. I tried only 2G, 2G/3G, only 3G, but no way..same problem..i hope an update can solve this..
I just bought my new One S from T-Mobile yesterday and everything appeared to be okay but now I can barely get it to hold a signal. Forget throwing it on GSM only because it will have signal for a whole few seconds before dropping it. I also am having Wi-Fi issues as well. It just intermittently drops the connection there as well... Not a great start!
whether im imagining this or not im not sure, But for me it seems like, When the Network signal increases, the WiFi signal drops, And when the WiFi signal Increases, the Network signal drops...
ive been noticing this for over a week now, So it cant just be coincidence..
I dont think my (or our) handset is faulty, I just think theres a pretty big bug in the ROM, and no matter if you switch ROMs they all use the same base at the moment..
This phone has great potential. But HTC need to be listening to us and release some updates. !!

I noticed the same exact issue last night. My phone will go to full signal before dropping whichever connection. I'm just glad this phone can handle staying on 4G without draining the battery like crazy although I can only imagine how much further it'd go with 2G.

Exactly the same here. But I had a different WIFI issue - WIFI won't drop but stay connected - even if I am far away off the AP.

that one is also a known bug.
On top of that, WiFi will sometimes stuck at "error" status with no ability to turn it on...
All probably related to the same network chip driver or "Radio"...
I have same network reception problem. When I am in a poor reception area it loose reception all of a sudden and takes a while before getting the signal back. I often toggle flight mode to force network detection. I also think the reception bars don't reflect reality; sometimes it seems I have good 3G reception but cannot surf the web. I fear it is a critical bug. The phone seems unable to handle correctly signal fluctuations and protocol changes (GSM, 3G, HSDPA).
I'm colletting more data about this problem.
First of all I don't have any wifi issue, or maybe I don't see this.
I have a modem with N standard and one with G standard and nothing of this have issue.
About the network issue in this days I never have, only when I'm in office and the signal suck a lot.
Q: Anyone that have Tmobile/mod rom with 1.70 RUU have this issue?

I don't have wifi issue at work with a powerful 802.11n network AP but experienced occasional fake/unstable/disconnect wifi at home with a poor AP which operates on no-one-knows-but-definitely-not-N network. I don't really bother too much cos I can always turn wifi off and on to reconnect.
In terms of 3G/H signal switching problem, yes, a bit annoy especially when playing online game on 3G but accessing internet is fine just need to sometimes wait a bit longer.
I am on international unbranded version in UK.
I've the same problem in France about 3G/2G and wifi on international unbranded version.

[Q] Phone changing network type by itself

So ive been having this strange bug it all started when i installed embyro 6-6 i was playing around with his network script the internet seemed to be faster then all of a sudden it stopped working I freaked out thinking i had broken something after some trail and error i switched my apn from wap.cingular to att pta and my internet was back but now it was LTE. I never had LTE in my area till that moment and wasnt sure if it was my doing or it just started recently in my area.
But with this change it came at a price as my signal strength went from -91dbm 11asu mobile network type HSPA 10 to -112dbm 28asu mobile network type LTE 13 but when i make a call it jumps to the HSPA and afterwards it goes back to LTE I thought I was getting the best of both worlds good reception when I need it and faster internet. But im posting about this weird problem is because recently my phone connection has just been turning off completely having 80% time without a signal which is draining my battery like crazy. If i call or text myself when it shows up as 0dbm 99asu i will still receive the call or text so im not sure if the phone is really not receiving a signal or what. If i put in a code like *3282# the phone will complete it jumping back into HSPA and after awhile go back to LTE then turn off completely.
Anybody have any ideas what would cause this any help would be greatly appreciated im thinking about restoring to stock then starting over to see if that helps. Im currently running pac 10.1 rom but this problem persist over wipes and new roms, changing radios I even went back to skyics for a bit and same thing.

[SOLVED] [Q] Weak signal / Drops to roaming

Hey Guys,
i am on drei.at (3-AT) and since i upgraded from CM11 to the lollipop factory image (currently without root) my signal is much weaker than before. My new baseband version is M8974A-2.0.50.2.21, reverting back does not make a difference. I had the same problem with my Nexus 4 which i dumped for the Nexus 5.
The months before i updated the phone everything worked normal and as it should but now if i move the phone from one room to another or even take a walk outside it will loose the connection to the carrier and changes to roaming. The real problem is that it get stuck in roaming and cant get back to 3-AT, the only way to fix it is to restart the phone or search manually for the net.
After that it works till it drops the connection and the whole process starts from the beginning.
I can only compare the signal strength with the normal signal strength icon.
Work before 2-4 bars (maximum one connection drop per day)
Work after 1-2 bars (connection drop around every 10 minutes or if i change the room)
Home before: 3-5 bars (no connection drop)
Home after: 1-3 bars (many connection drops depending on position)
I hope you can give me some ideas to fix this. Thank you for your input!
Greetings

Flash the old baseband. http://forum.xda-developers.com/goo...t/modem-nexus-5-flashable-modems-efs-t2514095
As written i tried a bunch of older Modems but had no luck. I tried one of the later modems and now i'm two days on M8974A-2.0.50.1.17. For now eveything works normal again!
Thank You!
I was having problems with the modem that comes with the Nexus 5 factory Android 5 image and flashed to baseband m8974a-2.0.50.1.16 (Android 4.4.4 radio). That improved my signal strength some but I'm still getting signal drops, just less frequent when the phone is just sitting on its charger in a fixed location. I'm in the USA on AT&T's network. Do you suggest I try the baseband radio M8974A-2.0.50.1.17, even though that is only included with a version of Android listed for certain countries?
I had similar problem although im in Europe and problem was in APN settings....after days or tying to set my APN it worked finally and i was able to catch LTE that disappeared after upgrade to 5.0 along with poor signal and dropouts off the network completely.
cause my carrier support was bad even they provided me half correct information..
about flashing another baseband they are total noobs and dont even know what the baseband is...
Any way connection is still poor but at least constant even with LTE with 5.0 baseband.

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Samsung Galaxy S10e's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
I don't go by the bars I go by the dBm's. The way this phone reads dBm's you pretty much show no bars after 117 dBm's. All other phones I've had showed 1 bar at 117. -97 dBm right now but still only have 3 bars. Should have full signal. -97 is pretty good. Anyways, I have an app that shows dBm's in the notification shade and that's what I go by. More importantly is the fact that my unlocked 6t has Volte with TMobile and my S10e doesn't. Sucks.

The 4G signal is way less good than with my ex Huawei P20. And when it goes from bad reception area to a good reception area, it takes a lot of time to catch the actual signal, sometimes I even need to put on plane mode and then put it off.

This. Takes a long time (minutes) to capture a signal from one area to another.
Anyone has experience with dual sim use in this phone ?
I barely get connection on the second sim and feels like the first sim has even worse reception when a second sim is inserted.
I got this phone like 2 weeks and very disappointed for cellular strength. As mentioned above, often i have to put on airplane mode to get connected to the internet.
This phone has serious problems with reception. It never really bothered me, I got this phone since launch, (exynos variant, dual sim) but now that I don't have broadband until my new provider sets up their network in the house, I have to rely on my mobile data, and it's amazingly bad. I have 2 sims in the phone, but it doesn't make any difference if I remove one or other. I'm in the UK, it could be Vodafone's fault, however I tried my sim in my previous phone (honor 8) and the signal was better (in dBm ofc) and I also tried my gf's sim in my phone and the signal was worse in my phone. I've spent days searching for solution and it turns out Samsung might went cheap on antennas so there isn't much to do. I've tried some 3rd party apps, tried to force only 4g, also tried 3g, reset network settings, reset access point etc; no luck. I'll transfer my number to an other provider and hope that it will help a little bit but to be fair, I don't think it'll help.
