Dropping network connection and other bugs on M8 - LineageOS Questions & Answers

I have installed the Nightly on my freshly wiped M8. I encounter some weird bugs. I have a international M8 from Germany. After every reboot my Pixel Launcher settings seem resetted to a stage a fews minutes after first boot. Some icons are in the right custom place, but I have changed locations and set up folders, which will be gone after reboot. Same with my wallpaper.
My bluetooth devices like Pebble Time or my Megaboom don't connect any more and have to be paired again.
My primary keyboard (BlackBerry Keyboard) is deactivated in settings and default Gboard active.
But the most annoying issue is the inconsistent network connection. Sometimes it works for hours, sometimes only minutes. The mobile network connection gets lost und won't come back until switching flight mode on and off. That's a really massive problem.
Until official Lineage release I ran an unofficial LOS port from xda here without mentioned issues.
Is there a solution or am I alone with this bugs?

Wifi issues

The wifi works fine for a while and then just dies. The wifi icon is still in the statusbar but no matter what app I open that uses the internet connection, nothing will ever load and Whatsapp messages will not be sent. When I disable wifi and re-enable it, there's a ! next to the wifi signal bar stating there's no internet connection and of course, none of my internet dependant apps work still. I have to reboot my phone (shut it down and turn it back on; apparently they never thought of adding a restart option) to get my wifi to work properly again. This happened a few days ago as well and I really hope I don't have to reboot my phone every couple of days to get my wifi working. So any suggestions? (No suggestions that include flashing a custom ROM on it or rooting it!!) A factory reset won't help because I bought the phone with Android 6.0.1 already pre-installed. I have the security patch of july 2016 installed.
P.S. My 4g internet works fine.
How about giving rebooting the router a try.

I have a similar error.
That my Nexus partially can not access the Internet via wireless, to which it constantly changes between the wireless and mobile data.
Does this have to do with the "intelligent network change" setting, if so how can you turn off the setting, in marshmallow is this setting not available.
The trouble also occurs with other routers.

I did that the first time it happened since my router tends to freeze once in a while, even with the weekly schueduled reboot. But the thing is, my iPad still had internet while my Nexus didn't so it was definitely on the phone's end. I did a quick Google search and a plethora of other cases popped up so I knew I wasn't the only one. Apparently those wifi issues have been around ever since the update to 6.0.1 and the fact that Google did absolutely NOTHING to fix it those 9 months is just ridiculous!
Hi!
You've got the option to try the Android 7 (Nougat) Developer (now released: Preview 5) version.
Works fine and stable for me, and there is a slight chance that it will help with your problem.
Just join the: android.com/beta
And you can always roll back to your current Android version.

wifi keeps disconnecting on nougat

Anyone facing this issue
Does anyone know any fix
Yes mines the same, wifi works fine for a short amount of time then disconnects, after it cuts out goto wifi settings and all I see is scanning and no wifi devices. only way I can get wifi working again is a reboot but then I get disconnecting again after short period of time!
EDIT: I would just like to add until I updated to nougat yesterday I've never experienced this issue and I did a master reset straight after installing nougat.
I am having this same problem. Any fix for this?
Same thing here. It happened to me after the first night. I thought maybe something was corrupted after the upgrade, so I did a full factory reset yesterday morning. Everything worked fine until I got up this morning. Looks like something over the course of the night causes this to start.
Things I've tried without success:
- factory reset
- rebooting
- removing and re-adding wifi network
- tested all other devices in the house (no other device is having an issue)
- tried both 2.4 and 5ghz networks (issue is affecting both)
UPDATE: After a few hours, I turned wifi back on yesterday, and it's been working fine since. I made no changes to the phone.
Faced same problem with developer preview
Before the official release of Android 7.0 I installed two Android beta preview, 3 and 5, and had the same issue I uninstalled the previews and had no problems with version 6.1. I hoped that this would be fixed with the official version but It wasn't, Im still facing the same problems with wifi disconnecting.
Edit: When I had the previews the only way that the phone would seem to remain connected was to go into the router options and change the client lease time. I never fully tested this because I uninstalled the previews within a couple of days. I guess I'm going to have to test it this time.

Maybe this thread could help you guys, didn't try, and as it is for nexus 5, do every operation carefully.
Flashed back to 6 as the WiFi issue was unbearable, working perfectly fine again now. I was also getting major battery drain on 7.0.
Hi
I found a strange solution working for me. I had bluetooth disabled, since I have enabled bluetooth today, 5 GHz connection is stable - Pls test it and update. And pls don't ask me, why these two protocols are in any way related...

Didn't work for me.
This problem had disappeared for weeks and then started rearing its head again yesterday although I had made no changes to my phone. For the record, it's happening on both frequencies for me.
Last time, the issue magically disappeared. After it didn't go away over night, I restarted my router this morning, and now it's working fine.
To clarify, I don't think it's router related, though. I have an R7000 that's working perfectly with all other phones and other devices in the house. It's the same router the 5x was connected to before Nougat started causing these issues.
Apparantly 7.1 solves the issue

Do you have wifi issues? Is my Nexus 5x defective?

I don't have issues to connect with my router, though nearly every day there is a moment where websites don't load at all. Then I need to turn wifi off and turn wifi on again and then it works. Very annoying.
Is my Nexus defective?
I have just noticed that I have posted in the wrong forum, sorry
I dont have any issues. Are you stock? Have you tried other kernels / roms ? Have you tried to isolate the problem to the 2.4 or 5 GHz band?
Stock Android 7.0, there is no option to choose the band in Android 7, but I have already had this issue with Android 6.
Mine also has wifi issues. Sporadically disconnects and takes ~30 seconds to reconnect. Makes webpages, snapchat, and other apps not load all the time. Like you said, turning off and on wifi seems to fix it for a few.
I've tried forgetting the network, reconfiguring my router (it does this on other networks too), reflashing stock. I had this problem before I sent my phone in for the bootloop issue, and they sent it back fixed and it still does this. Thought maybe it was adblocking having issues, so didn't install that this time. Still does this. It's not TERRIBLE since it's connected maybe 70% of the time but it still is inconvenient

To isolate the bands you would have to disable the bands on the router.

GPS Issues on N based roms, please help

Since I installed the first N OOS build i have issues withmy GPS,
every few seconds it lost the lock and needed a few seconds to reacquire it.
Also sometimes it does not acquire ay lock at all and need a reboot to work again.
As far as I can tell the issue happens with every android N based OxygenOS.
And also with Lineage OS 14.1
I tryed clean flashing booth and it did not change anything.
Now I flashed back to the last MM based community build and it works no lost of GPS signal, reasomably quick fix.
Does any other users also have GPS issues with N based roms on the OP3?
How can I solve the issue or at least find out whaty causing the issues?
Funny you mention this. I use my op3 for my topo maps when I hike and I have found N based roms to cause the gps to require a relocking. Also, the gps is noticeably less accurate.
Anyone got an explanation/solution?
good to herar that I'm not the only one with GPS issues.
Now the question is how to fix those?
I am also facing GPS issues since Oxygen OS 4.x.x, before that I never experienced any.
Sometimes it take 5 to 10 minutes until it finally fetches a GPS Signal but it is still very inaccurate then.
Hopefully the new OOS 4.0.3 update helps, but I doubt it since there is no mention of GPS in the release notes.
I also have this issue, the only resolution I had is to switch on WiFi scanning. After turning it on GPS has been a bit better and locks to the correct location quickly.

Ok I found out something new when I set mobile data to 2G GPS works great also on the 4.0.3 OOS ROM.
And since people complained since the start that some have issues with GPS and 4G I guess the issue really is that if some particular frequencies are used GPS suffers. Apparently something changes in N ROMs that makes the issues appear for more users.
Interestingly is that flashing Modem Firmware has no affect so the issue is in a part that is in the android kernel itself.
https://forum.xda-developers.com/oneplus-3/help/gps-issues-t3416544
Every time I turn location on, I get the "improve location accuracy?" prompt. Every single time.
How can I stop this? Never had this before, usually goes away after one enable.
Another strange thing sometimes the GPS cant get a lock and the only way to fix it is to restart the phone.
the bew Open Beta 12 based on Android 7.1.1 seams to have resolved my GPS issue really strange
Hi - I also do have heavy problems with losses of GPS- signal at the OP3 since months. Especially while using LTE the GPS gets often lost. Since 5 weeks I am working/struggeling with the OP-support a lot - but no changes till now. @David: "Open Beta 12" has solved your problems?? what is this concrete?
i do have the problem...... from 4.0.2 updated to 4.1.1 and now Beta13, the problem still there~!!
On my phone gps signal gets lost always at the same location and when lte is active. On any other location gps works perfect. When i disable lte everything works perfect. This has happend on any rom. I think this is a hardware problem and can not be resolved. The only solution is disabling lte or using a different provider. I am using o2 in Germany, the problem does not happen with other Providers. Different Providers have different frequencies, this might be the difference between o2 and the other providers.
I do have O2-LTE too and it is "under suspicion" in Germany. But in February I was for 4 weeks in Florida and travelled a lot using navigation. The provider was AT&T - and I had very often losses of GPS-signal too.
I can confirm, that the problem happens with different ROM, but not at only one location - it happens everywhere.
But what can we do? OnePlus is working at this problem since months without a solution - and the customer with this bug really have to accept it "for zero"??
Hello @OPFan , did you get help from the support? Or could you resolve the problem?
3 months of contact - lots of bubbles - no solution
try downloading the "Gps Test "app then enable GPS and open the app and click on the 3 dots > AGPS > Clear and update

this was one of the thousands of tryings - but also with zero effect
I'm having a lot of GPS issues since I've been using OPO or OP3.
I sold my OPO because of the bad GPS. Now I have the OP3.
On both phones I used custom ROM Cyanogenmod.
I sometimes had bad GPS reception, but this was fixed under Cyanogenmod doing this: Disable GPS, Disable Data, Enable Airplane mode, Disable Airplane mode, Enable Data, Enable GPS, then wait for GPS reception and start navi app.
Last week I flashed my OP3 with another ROM (AOSP) but this only made it worse!
I use my phone as car navigation daily, and while navigating, it finds GPS and it loses GPS every 5 seconds (using WAZE app). It's incredibly annoying. Using AGPS or any other "fix" found online doesn't fix the problem.
When using another navigation app, like Google nav, it's works better (because Google also uses LTE). Clearing cache or unistalling and reinstalling the WAZE app doesn't fix the problem.
Conclusion:
It is totally not related to your provider because they are working on fixed standard frequencies and I've been using the same provider on both phones.
It's also not related to the hardware only, because it was working on my OP3 under Cyanogenmod. So it should be related to the hardware driver included in the ROM.
Maybe this gives anyone an idea?

I have also GPS issues. It works well in gmaps, but it is unusable in Waze.
I thought AOSPA was causing it so I cleanflashed latest OB, but GPS issues are present there too

LG Wing Wi-Fi not working after Android 12 update. Any suggestions on fixing it?

My LG Wing Wi-Fi and Bluetooth settings stopped working after few weeks running Android 12. I have reset my phone and after 3 weeks it's the same problem. I just updated for 5G support(V30d-Jan-10-2023) and still the same problem. Is there any solution?
Hello, where are you and what carrier do you have? I'm in the United States and have verizon. So far I've had no issue with Android 12 on my device. If you have Wi-Fi calling turned on you might try to disabling that. Just a guess but maybe that could help.

Hi I am in India and I use Airtel. I tried Wi-Fi disabling but it doesn't work. Phone is sluggish, UI is crashing frequently. Don't know what to do.

Backup what you need to keep,and factory reset it.If that doesn't work,use LGUP and downgrade the firmware.
So I noticed something strange. I went to another city for couple of days and my phone worked just like before. The Wi-Fi is working fine, the UI is not crashing, Settings is not crashing(Network and Battery was crashing previously) and no slowdowns whatsoever. But as soon as I am heading back to my home it starts slowing down again.
The GPS location with the most time logged on my phone(place where I use my phone the most) causes the phone to slowdown. Is Android 12 deliberately slowing it down? Did anybody face similar issues with Android 12 on LG or any other Android phone?
That is very weird. I have not noticed any slowdowns at my home versus anywhere else with Android 12. My Wi-Fi and Bluetooth also work perfectly. Before a factory reset you may try resetting the network settings.
Apple made their iPhones slower on purpose after year or so of use. Android might be trying to copy that feature in Android 12. It doesn't makes sense that my phone overheats, eats up battery and have super slow UI all of a sudden. Even after hard reset it's the same issue. I have noticed it working fine after I leave my home for sometime. Or maybe I am being paranoid.
Also I have been noticing a bug from Android on LG Wing for past 1 year. There is a small icon for location which appears on top of your phone when it is trying to locate you. But that icon appears randomly despite my GPS is turned off. Seems to me that Android is deliberately accessing your location no matter you turn GPS ON or OFF. But LG UI still shows GPS icon.
