LG G3 D851 dropping signal (losing data connection) problem - Android Q&A, Help & Troubleshooting

Hi everyone.
I'm having an issue with my G3 D851 this past week with losing signal completely and I get `ActionManager Service has stopped' error appears, only 'ok' appears as an option appears as an option for me to clear it. if in any app, boots me out of whatever app I'm in, if not in an app the screen kind of flicks and and reconnects. I hit ok and get the signal back for a matter of seconds or minutes and it does it again. I get the network strength indicator spinning then it comes back. my phone is a D851 that is running fulmics ROM 5.3, and android version 6.0 (for 4mths at least) please let me know if more specific info is required on my phone to assist. I'm a bit of a newb to problems. my last 3 phones I've been able to root unlock bootloader and flash a custom rom and have no issue for the life of the phone by following great tutorials. this problem seemed to be a once a month thing, that became once or twice a week.. now it's constant rendering the phone pretty well useless.
my problem sounds somewhat similar to this thread but I've not wanted to mess with anything being the fulmics is already tweaked and the settings within that seem to be the same already as what this thread describes to try as fixes. I read this as more being an LTE issue as opposed to complete data loss issue.

I`ve not installed any new apps or removed any or made any changes when this started. no setting changes, no updates. everything works as normal on wifi .. this is only a data issue. since this problem, I have done a complete backup and wiped and reset using TWRP wiping the cache and system data. same result.
any assistance would be greatly appreciated. I'm hoping this is software related as opposed to hardware. with 6.0 and this ROM this has been the best phone I've ever owned.

[Q] Vibrant (Bricked) Not working-Reboot Loop

I have never posted here before though I troll and check out what is going on about my Vibrant often and have not seen this directly answered yet, so here goes.
I downloaded and installed the official froyo the other day from Kies Mini.
I have never attempted to even boot in recovery mode.
I have never attempted to root, rom or anything that you amazing people somehow figured out.
OK, so that should help get us somewhere to start.
I noticed today that my notification bar showed the signal as the 0/ (i don't know how to place that symbal correctly) as no signal. I let it go for a few minutes because sometimes Tmobile loses signal in my building. I noticed it outside on break and I tried to reboot. It rebooted but kept rebooting. I removed to battery and its still kept rebooting after letting it sit without the battery. I tried rebooting in recovery mode and deleting the cache memory (don't want to delete user info yet unless that is my only option to get fully reset) and its still rebooting.
Basically after I rebooted the first time, its runs slowly at the S, finally gets into the homescreen, shows signal (but none of my apps, no screen responses at all, just vibrates a few times while switching from no signal to signal) then reboots.
I am pretty much at a loss here. Would love any helps I can get.
Bump, please I don't mean to be annoying, but is this something I am going to have to revert to factory on? I saw someone else had a bricked phone after download and reboot constantly like me. Ugh, to wait so long for Tmo and now this??
The BEST thing to do, if you havent modded, or rooted is to take it to yor local t-mobile store if you have one. If not, call customer support and have them send a replacement.

[Q] Urgent: suddenly lost my phone signal

Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.

Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:
http://androidforums.com/samsung-ga...connectivity-but-no-idea-why.html#post2722784
He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.

Wifi Periodically Dropping out

Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.
RTFM THO FFS! Potential for complete brick if you get it wrong

just..want..to..delete this post.........and I can't...so there is now filler here....GG k thx bai
It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?

S5 The Galaxy Project Issues

Before going into detail, I feel the need to say that I am a complete noob but I can understand most technical procedures. That being said..
I had a S5 from Metro PCS (SM-G900T1). I attempted to root this thing and couldn't successfully do it so I flashed the latest firmware for T-Mobile. My phone is now SM-G900T. Within both these points, I still didn't experience any issues.
When I successfully rooted my phone, I installed the latest ROM version of The Galaxy Project. Since then, I've been experiencing 3 issues.
1.) My 4G and LTE have been switched to H, H+ and 4G. I can't switch it back by restarting my phone, changing VPNs and changing connection types. More importantly, I don't know if my service has been downgraded. Any help with this will be greatly appreciated.
2.) My phone keeps sending random service reports. There's no way for me to check out why as they happen really quickly. Is there a way to disable this or at least check out the reason why?
3.) lastly, this is a minor issue and I don't care much for it but I can't access my themes without my phone saying that TouchWiz has crashed. Nothing happens after this and my phone is fully usable but I'd still like to explore everything since this is my first custom ROM.. Any help at all is greatly appreciated.
Edit 1: It appears that the H+ and 4G are equivalent to LTE speeds but slightly slower. I have tried to coax the changsetting by tweaking the build settings but no luck. Also a new issue has become a problem for me.
After a while of no use or after charging, the screen becomes unresponsive. The power button works but I cannot restart/turn off my phone and it requires me to pull the battery every time.
Try another ROM to see if the problem goes away. I suggest you give this a try: http://forum.xda-developers.com/galaxy-s5/development/rom-popwiz-telstra-note-5-port-v3-0-t3265997

LG V30+ screen freeze problem

Hello guys. Recently after the oreo update, I'm facing a lot of issues. Main thing being the screen freeze. The phone hangs suddenly at a screen and nothing works. It doesn't even reboots on its own, if I leave it, it will stay like that forever. Only way to start it back is to hold power and vol down after which it reboots. Also i have noticed, before this happens, there is a slutter and lagginess in my phone, like while switching apps with the recent app navigation icon, while typing, or bringing down notifications, everything seems to be a bit laggy giving an indication that the phone is going to freeze. And I reboot it, I have seen that the battery drops by 5% suddenly and phone gets hot. Can someone please help me identify the problem. I can do a factory reset, but I won't be satisfied until I know what's wrong so that I can prevent it happening ever again.
@SHIVALP123 Sometimes updates can cause issues especially if upgrading to a other android version. Factory reset should fix the problem and for future a backup and clean wipe for different android versions. Could just be a malfunctioning app or files that got left behind maybe. I'm loving the V30 just recently upgraded from 6P. Oreo is fantastic and no issues so far to speak of. ?

Ohh. Okay. Thank you. I have deleted many recently installed apps for now. No issue since morning, battery life has improved quite a lot. Got 8:15hrs of screen on time with 4G on all the time and all the time the net was being used. I wonder how well it will perform on wifi. I just hope i don't have to reset it now. ?
