I recently moved to a new carrier that is just rolling out its AWS network. So, for the first time, I am experiencing frequent reconnections to the network (it just barely reaches my basement, for example).
It seems there are Android bugs that only show up under repeated loss/regain of signal.
One common experience is that without a manual reboot or reset of the radio, the phone won't reconnect even if you move into an area with high signal. For a list of experiences going back a while, see
http://code.google.com/p/android/issues/detail?id=2845
I've also found that upon reconnection, GPS often doesn't work -- by that I mean that apps that make calls to the GPS receiver can't initialize it. No icon in status bar, etc.
Anyone else with similar experiences, tips, tricks, etc?
Once again, this is an issue that only seems to affect folks that are frequently going in and out of cell signal range.

Hello, folks!
I have a rooted I9100 (Android 4.0.3 stock from Vivo, baseband I9100VILP3, kernel 3.0.15-I9100VJLP7-CL371396 [email protected] #3, compilation IML74K.VJLP7, CSC I9100UVILP3).
Sometimes I have problems turning on WiFi, it keeps always turning on and neither become active nor allow me to turn it off again. I then need to reboot phone to fix it (when it reboots, WiFi comes turned on and gets on normally).
Another problem I have with it is that sometimes (average of 4 - 5 times a day) phone loses registration with carrier. It completely loses* signal and shows a "prohibited" icon where signal strength is shown at status bar. (Edit) Sometimes it comes back again in a few seconds and sometimes it stays at that state, making me have to reboot it to fix the problem (turning on and off airplane mode doesn't work; in fact, with registration lost and trying to use airplane mode, it doesn't turn off and only fixes with reboot).
*Actually, it doesn't lose signal (can be seen in "settings - about phone - state" screen uploaded), but only unregisters from carrier.
(Edit: screen/phone language is Brazilian Portuguese)
I've downloaded another modem driver but never had time to test it.
I don't know if both problems can have the same cause, but both of them are very annoying (especially signal loss) and I'd like to make some tries to fix them, so if anyone knows what can I do (even data collection to investigate them), your help is very appreciated.
Thanks
Additional test (ServiceMode)
When I was in the forum to post this thread, I've noticed this other thread and I've decided to use ServiceMode code (*#0011#) to investigate further at the next time my cell lose signal. Unfortunately, it showed absolutely nothing. Literally nothing (just "ServiceMode" caption and no text on the screen below).
I just spent the time to post this because I know that, even if it has shown no information (on screen), maybe it still can be a clue for the cause of the problem.
Thanks
Pls help!
Does anyone have some light to shed on this case?
Please, I do really need to fix it, at least the signal loss problem.
Thanks.
Same Issue in the US on Tmobile
Mine started doing this just a day or two ago. Exact same issue. I can kind of operate on the EDGE network but 4G fails, only WiFi seems to work. T-mobile doesn't seem to have a fix for it.
Changed to MIUI
I've just changed to MIUI (reflashed modem also – now it is ZSLPE instead of previous VILP3).
I still have issues with carrier register loss, but until now it always reconnected after a few seconds. Maybe it is a carrier issue and not a phone one.
I don't turn on WiFi a lot, but all times I've tested it, it worked well.
Another thing I've noticed with this change is that battery temperature while charging used to reach 48°C (118°F) or even 50°C (122°F) while battery level was low (less than 50%), but now it stayed around 35°C (95°F), which is completely acceptable.
This is a serious problem with the functionality of my phone. Not only am I having the ghosting/burn in issues others are complaining about and quickly waning battery life, but now when I activate my GPS, my mobile Internet becomes disabled and my signal drops. As a result, my apps (Maps and, more recently, Pokémon GO) lose the ability to communicate to their respective servers. Because of this, GPS then drops, while the mobile Internet kicks back in. Once that happens, the GPS tries to re-activate, and the whole horrible circle begins again.
I can't find any fixes to this issue. I downloaded GPS Status from the store, but nothing I could see in the app solved my problem. Anyone have any ideas besides a factory reset?
[Q] [pseudo-solved] Device occasionally loses Internet connection for WiFi & cellular
The Problem:
I recently upgraded to the Motorola Moto X Pure Edition and have got almost everything running smoothly except for one thing - every so often, (between 2 and 8 days) the device will completely lose its Internet connection for no apparent reason, displaying the little exclamation point next to either the WiFi or cellular signal strength indicators. It usually happens after transitioning between WiFi and cellular (leaving home, arriving home, etc.).
Once the device enters this state, no amount of toggling WiFi, data, or flight mode will allow the problem to be resolved. The device will simply refuse to cooperate with any type of Internet connection at all, even though it still has an IP address, as reported by the ifconfig command in the terminal. No addresses, local or otherwise, can be pinged.
Rebooting the device always brings it back. Clearing the cache and dalvik cache seems to make it last a bit longer, but this has yet to be confirmed.
Troubleshooting efforts and device configuration notes:
A web search turned up nothing at all, although two other people in the original thread on the Moto X Pure Edition Q&A forums revealed that I'm not the only one with the problem. My device is running the stock, Android M Rom, (rooted) but others have reported the same issue with a non-Motorola Android N ROM as well as on the stock un-rooted Rom.
This leads me to believe that the issue isn't Rom-specific, and may not even be device specific. With all this in mind, does anybody have any good tips for troubleshooting this? Any ideas for what could be causing it or how to fix it?
Thanks!
TL;DR? Device loses all Internet connectivity on all connections, usually after transitioning between Cellular & WiFi, on stock-rooted Rom, problem reported on stock and non-Motorola Roms as well. Software or settings conflict suspected.
Update: Hard reset; problem solved. No cause was ever uncovered. See post 7 for all the details.
Internet loss breakage Logcat
Here's the Logcat, if that helps. I tried getting a complete one, but had to cut it off after close to 45 minutes, so there still should be plenty there to go off of.
Any ideas?
Anybody? Any ideas at all? I'll even accept shots in the dark at this point. Made it a record-breaking <9 days, but the problem came back again, even with "Cellular data always active" switched off.
anything? anyone?
Ran into the issue again today, even having left WiFi manually turned off. Any ideas on this? I'll even take shots in the dark. Anything short of hard resetting and reinstalling apps & reinstating settings one-by-one.
Internet dropped out again...
Had the issue again today, but this time caught it "as-it-happens" (as I have only once before). This time, I woke the phone up and saw the exclamation point over the WiFi signal strength indicator, but was still able to use the LTE data connection. Resetting the cellular radio put a stop to that as well.
Any ideas at all? I'm taking complete and total shots in the dark at this point too.
Still losing Internet connection on WiFi, then cellular as well
Same deal again today. Any ideas at all? Anything I can do short of pulling the plug and hard resetting?
Hard reset; fixed
Well, I ultimately pulled the trigger and hard reset the device. The problem appears to have permanently vanished, but we will unfortunately never know its cause.
I'm having random connection drops on the latest EU build. I tried reflashing the ROM, installing akhilnarang's vendor, changing kernels buy still no solution.
The phone will work well but suddenly lose mobile data (4G) connection for a few seconds and then come back. I noticed the VoLTE icon also disappears with it and then comes back but the network signal lines (on the status bar) show full signal the whole time.
Also, I'll suddenly drop a call sometimes and this is accompanied by the network signal lines disappearing (implying loss of network signal) and then coming back in a few seconds.
I have a very good signal from my carrier so that's not the problem. Also, the phone seems to work well for sometime (few hours) after a restart and then this "bug" comes back and I can't find any kind of solution to this.
This problem started to arise after I flashed the latest EU android Q build.
This bug is annoying and frustrating especially while playing online games.
Any kind of help will be greatly appreciated.
Thanks.
Many problems after Android 10 update
I have the same problem after updating my smartphone to Android 10, with no solution !
While i'm using data connection, i don't receive all the notifications in time.
I'm facing another weird problem which is the phone does a fast reboot after that it freezes for some seconds.
Same Ish
Same issue here, when streaming or downloading, my wi-fi or data connection will randomly drop and wont reconnect unles i reboot. Then will drop again once i start to download or stream. My other phones or laptop no issue.
Connections are good, as im writing this am streaming on my laptop but my poco refuses to connect to our wi-fi. Issue only popped up after the latest update
Hello everyone,
Sony Xperia 1 III (QX-BC52)
I found two problems or bugs:
1. PROBLEM WITH MOBILE DATA:
This problem does not occur on the wifi network, but only when the phone uses mobile data. I will also send you a couple of different videos that I recorded with the screen record application so you can see exactly how the problem occurs.
First, for about ten days, I noticed that the icon from 4g was disappearing from time to time, and then I tried for days to find the problem and to see when and why it disappears at times and somehow I succeeded in that. This problem is present in all applications when a video is played and the sound is turned up to maximum, as soon as the sound is reduced to about half of the icons with mobile data (4g) do not disappear and the mobile data transfer works normally without interruption, or only press pause for fix this bug.
I will upload one or two videos in link bellow with situation when I show this bugs:
https://www.reddit.com/r/SonyXperia/comments/vyc7r3
I will share list with all the applications in which this problem occurs that I have personally tested:
- Viber during video calls (occasionally)
- YouTube (every time)
- Facebook (every time)
- Instagram (every time)
In addition to this problem, I noticed that when downloading applications on the 4g network, sometimes the applications are downloaded quite slowly if we keep in mind that the phone downloads them on the 4g network. Sometimes it takes a few seconds to download a 20mb application and sometimes ten seconds, in both situations the signal is full.
2. PROBLEM WITH MOBILE NETWORK:
It also occurs frequently in areas where the phone mainly uses the 2G network, then the connection is often interrupted during the conversation, and therefore also during that period the phone cannot establish a connection, it throws out the message that there is no network even though the area is covered by the network.
I am noticing the same problem, so looks like its a problem with this update. Nothing to do with a particular region or carrier it seems.

My Sony Xperia 1 III is a model for the European market, and a friend has the same phone, but his model is for the Asian market. Both mine and his phone have the same android version and the same software version and he has the same problem, so it doesn't matter what market the phone is made. I tried with another operator's sim card, but the problem is still there. The problem is obviously in the software.
Yea i notice that too. i thought my sim card was bad. f###K after i just made the decision to say on a12..
My XQ-BC62 does it too. When there's loud midrange, LTE drops and the cell indicator flickers. Logcat is so junked up during playback that I don't even know what to look for.
If I output a square wave 22Khz sound, the audio power scales up and down and cellular cycles on and off. It seems like part of the phone is out of power and it's not managed well.
This is an incredibly stupid fault but good to know about. The last thing this phone needs is even more cellular drops.
Im having a problem right now, not entirely sure what exact market my Xperia 1/iii (XQ-BC72) is from, i think Oceanic? As i live in New Zealand but at the moment and for the last week and a half or so i havent been able to make calls and texts either fail a few times then send or take forever to send, its really annoying me cos i also have to use my phone for work, and when i cant make or receive calls most the time it sucks! Aswell as it will say "Calling" when i have Signal Bars, but wont make dail sound/go through or it'll just fail!
