[H918] Phone Disables Several Features After Battery Dies (LOS16 + Gamma Kernel 9) - LG V20 Questions & Answers

So I have my phone rooted, mainly use it for music and video chatting with my fiancée (away at school). I currently have the latest LOS and Gamma Kernels installed. No BusyBox or anything like that. Just Magisk with V4A and the debloat module to get rid some of the baked-in apps that I use alternatives for.
I seem to run into this issue on a pretty regular basis. I'm noticing that it tends to happen most when the phone dies, but many of the features become unresponsive. The fingerprint scanner stops working, WiFi stops working and becomes unselectable, mobile data disables itself, the navigation bar becomes mostly unresponsive and does nothing when you tap the home or task manager button. The phone basically becomes pretty unusable.
I'm wondering if maybe this is something that I'm doing, or if it's maybe a bug within the LOS software? Is there any known fix for this? Am I maybe doing something wrong when flashing the ROMs and kernels?
Often times, maybe once every 3-5 weeks, I have to wipe the phone and re-flash everything, which is getting pretty annoying at this point since I often lose data on some of my apps, pictures that hadn't been able to back-up via Google Photos, etc.

[Q] Device gets Awaken ALOT During Mobile data (But fully silent on WiFI)

Hey guys, i have been used S5 since 5 months with this problem (from the start) i am not sure, i cant think it as it's malfunctioning (by internal) so i am sure it's something else. So far, i used firstly STOCK ROM (4.4.2 + upgraded officially to 5.0) On Both Update, i had Root, SuperSU.
Used official 5.0 update for months, and still had this problem about device getting alot of awaken wakelocks, like, every 3 - 5 min it gets awaken for short period, sometimes (like 1/20 of total awaken period) it is awaken for more then minutes, i couldn't find the issue, so i used it so. On WiFi, it's totally silent! nothing suspicious on stats, device lasts even long on stand by, but on mobile data (when screen is off) it just drops! like, 1-2%/hour (dunno really, may be wrong).
What i did is, get CM12 Latest nightly (5.0.2), furthermore i installed SuperSU as primary root, Tit backup, 7-8 xposed modules, now i installed amplify (Xposed module, helps find and kill wakelocks).
I have found many wakelocks, services, alarms. I reseted the stat, opened mobile data, let it be so for minutes like 10-20minute, and opened to see wakelocks, what i find is alot of wakelocks on different stuffs, mostly Google Play Services. I made it so they cant trigger the phone's wakelock more then once every 9999 second (to make sure i can find out the issue of the problem), now i killed so many that i even killed clock timer, ticker, GSM Broadcast things etc, so i get almost no notification, no any clock is even showing accurate cause if the wakelocks i limited. I did it, nope, it's still same, not less or more, i still couldnt find the issue, i killed or limited so many wakelocks, services and alarms yet i couldnt find it, i dont know what to do, i did install many, many, many times fully fresh ROM through odin several times, fully new installation few times, yet same problem occurs.
My question is, what can i do to find it? Amplify is greater than those Wakelock monitor things, cuz Amplify app finds them, and lets you set up how many times they can wake up the device every (x) seconds, guys i need help please could someone put their few minutes on this and troubleshoot it? i did everything i could (no, no any xposed modules are affecting it, on stock s5 rom 5.0 it isn't compatible with xposed, so xposed is not the cause).
Neither is FB Messenger app (if so, everyone should experience it) neither is Viber, nor any other apps (counting these cuz i dont have any apps that runs in background, from what i know...)
Also, last analyze. I set up Data connection monitor, and let it monitor total mobile data connection for +8 hours of being idle on charge, and found it downloaded 2.2mb of data in total, as of upload i dunno, it was however alot less than downloaded, i dont think it is really using my data, or? even so, it should even trigger during WiFi, why it only happens on Mobile data then?
THANK YOU ALOT for reading it!

Heavy lag

Hi guys,
Has anyone noticed heavy lag and freezing when using the phone. I don't have a lot of apps installed and i have disabled most apps that i don't use and the phone is still giving me issues.
Any advice is appreciated. [emoji4]
I switched from RAZR MAXX HD and this phone is a space rocket in comparison to my old Droid. Have you tried factory restore? Then if it lags - I would try to return it to Moto.
Check CPU utilization. Maybe some app hangs on. I've noticed that noozy (music player) lags like hell when album is over and player remains in notification bar.

I have the same problem, I tried to removing as much as possible automatic start calling but often when I uncheck the receiver this puts me "failed" in Rom Toolbox, I have tried Xposed Auto Boot module, but I do not feel that it works.
But for me, I have a lot of app instaled and my UI is very modified (Nova Launcher, Gravity Box, various Widget), so I know why he lag, but I still find it overheating lot and that's what most do slow.
Hi, I am having same issue. My configs was same as you, @Trinytix, but I had uninstalled all of them because lag issues. And now I continue to have same lag issues. When I use the standard cam for five minutes it become freezy and lag and sometimes I lose some photos. All the time it is burning. Just stops to burn when I leave it without work about 30 minutes. I think the problem is the snapdragon 810 but in other foruns some say that the problems with this processor was fixed.
I've been having similar issues, I got really into theming (using nova prime) the last couple of months and at the end of January the phone started to really lag hard. A couple weeks ago I stopped being able to open any apps other than the phone and google's messenger. I tried to factory reset from settings and could not (device gets stuck un the power down sequence), so I went the recovery mode route. reinstalled a fraction of my apps, put back a much stripped down version of my theme, and things were mostly ok, if a little laggy. However, the phone insisted that there was no SD card (internal or external) despite there being a 64GB card, which would sometimes show up when viewed in settings, some apps (podcast addict) were able to access the internal memory, but others couldn't (cameras, sms, photos, music). Yesterday the keyboard ceased to launch for more than a split second at a time, and would not take any input (you would not believe how infuriating this is unless you've experienced it first hand). In an attempt to regain some functionality I started uninstalling everything that I don't consider vitally important (bus app, podcasts, messenger) couldn't get through more than 1 or 2 at a time because multiple windows would stack telling me processes like "motorola" "android" and "media" had stopped. I did succeed in stripping away all the automation apps and theming apps (tasker, nova, icon packs, etc). I can't even place a phone call on the first try.
Oh and to add insult to injury I have to darned green lines about 0.5cm wide now.
Looks like hw problem or system got corrupted. Try to re-flash whole system but if is hw...

How stable/reliable is the S5 running CM12.1/13?

Hi all,
Currently looking for an upgrade from my Moto G and have a specific list of requirements (long-ish battery life, cheap-ish, ideally fast charging, ideally ANT+, ideally waterproof, accurate GPS for tracking runs) which the S5 seems to meet well. Only thing I dont think I could live with is TouchWiz (and the assosciated lag I would expect it would bring with it).
My question: how is CM running on these devices with regards stability and force closes etc. Can live with a small dip in camera quality and having never had a fingerprint scanner I wont miss it but really need a rock solid, stable device. Is there a better alternative out there (am also closely considering the Zuk - but not waterproof and possibly patchy GPS - and the Moto X Play - slightly more expensive and reports of lag)?
I'm currently running CM13 on my KLTE, and it honestly seems fine.
Battery life is just under 4hrs SOT.
It charges pretty fast IMO (About an hour and a little bit with a constant 1800mA @ 4.5V)
Though was I've read in a quick Google search is that CM doesn't support ANT+ ever since the s4 branch.
Never had issues when the phone's been blessed with water, Its a pretty tight seal all around.
GPS is accurate. I usually get a fix within the first ten seconds. Mind you I use GPS Status to download AGPS info to help.
I rarely get force closes but there are the occasional soft reboots with the phone, which seems to put it in a boot-loop when it does. But that could be my configuration of Xposed and other modifications that do that.
i dont like the in-use battery life at all, deep sleep life is insanely improved on CM13 i assume due to doze, you can buy third party extra large batteries that are also a replacement for the back cover
cm-12.1-20151226-NIGHTLY-klte = quite stable, think i had only a couple minor bugs, no crashes, my baseband is a little old, i tried some gps app from fdroid during a walk & it was as if the calibration kept changing... i passed the same spot more than once, it would be too far north one time then too far southeast another time & so on, but maybe it was storing literal data points (some other apps, especially map apps i would assume they might auto align themselves to roads), crashed the camera when using opencamera too fast or switching between it & stock camera, opencamera couldnt do 60 or 120fps videos even though the option was set
cm-13.0-20160116-NIGHTLY-klte = turning flashlight off kills camera (& the flashlight tile) until reboot, i was going through menus fast or something, the status bar crashed & then soft reboot was frozen on the loading face icon, i was hoping snapdragoncamera was enabled cuz i see it in changelogs, but i still see stock camera unfortunately...
charging is quite fast, from 0 to ~80% at least (this is normal for about every device anyway)
i havent tried any other versions yet, i dont have gapps, only been web browsing in lightning browser (from fdroid), trying kernel adiutor, notepad, little bit of camera, i dont have a SIM card yet, hope it works fine...
i believe i saw a modified TW rom that keeps the TW framework, but visually tries to be AOSP, the purpose of course is to be able to use the samsung camera & some of the other proprietary apps/features
My build is a KLTEusc smg900r4, with cm13, on first boot I had issues with the access points to the mobile network, but after I input one access point it found the rest on its own, only other issue is when sending long text messages it doesn't go through from some reason, overall very proud of it, much better than touchwiz

Need Help Finding Root Cause of UI slowdown

Hey all,
So I've had my S8 since launch and I've enjoyed it but I have an issue that I've been trying to pinpoint the cause of for a few weeks now. At a high level, if I reboot the phone in the morning, I can use it all day as I wish and it works perfectly, no slowdown anywhere and good battery life. I plug the phone in at night when I go to sleep and when I wake up I start using it again. Either right after I wake up or over the course of a few hours the phone begins to slow down with things like notification shade/app switcher crawling until I either a) reboot or b) change display resolution. Doing either of these "fixes" it until the next night and then again when I wake up I have the same issues.
I've been trying to figure out what's causing this. I've tried disabling features, uninstalling apps, etc.
One thing I have found is that when I'm having this problem if I force close 'System UI' in App Manager (this is just restarting that process since you can't kill it really) the smoothness comes back but it doesn't last as long as when I either reboot or change resolution.
My theory is that something is conflicting with the Android UI and over time it's causing it to slow down. Rebooting or changing display resolution restarts the Android UI so essentially same thing.
My first question is has anyone seen this behavior where the notification shade/app switcher (native UI not apps) slow down? I know there's at least some people on Reddit with same issue. If you have this issue does FC'ing System UI 'fix' it for you temporarily?
I'm trying to figure out what is running on my phone while I'm sleeping at night which is obviously causing this. Any ideas would be helpful. Oh also when I wake up and I go into app switcher it only shows like 3 cards where before I go to bed it would be like 10+ so something is killing apps at night too. I turned off Google backup for today and will reboot before tonight to see if maybe that's it.
Appreciate your help.
Thanks.
I've had my S8+ since the launch weekend on ATT, always connected to my Gear S3, and connected to my Misfit Ray. I've not noticed any slowdown of the UI. My AOD clock is slow to show the hands if the screen is off when I use the numerical clock AOD, but nothing else observed.
I would guess you've installed (or haven't uninstalled/disabled) some apps that are using a lot of background processes. I removed/disabled the few ATT apps on the device except Call Protect, and I don't use Gmail (resource hog). I actually use very few Google apps, they're just not very well coded, it seems (maybe a "goof off" day every week isn't such a great policy?)
In settings, go to Device maintenance, click on battery, and see if anything strange is going on there under App power monitor.
I've NEVER liked Samsung phones, and I've NEVER been interested in owning one, but I saw the Galaxy Gear S3 and fell in love, and truthfully, I bought the phone as an accessory to the watch, so I'm not an apologist for any shortcomings.
Instead of restarting, go to settings/device maintenance, what's the percentage here? go to optimize, does it help? which apps use the battery most? How much RAM is available. If nothing shows up, you probably would need something like wakelock detector (it needs root) to trace apps usage, especially at night. Also you could try to force stop other apps and see which one is interfering? For example phone is slow, force stop first 10 apps, if not fixed force stop next 10, if fixed, next time force stop one at the time from that batch of tens.
Mines just started doing this the other day. I think I have an idea if the problem, I'm just trying to find proof at this point. I recently downloaded this all to let me see the upload/download speeds if my network in the notification bar. It lets you set the refresh rate, to which I set it to 2 seconds, which I knew regardless would tax my system, I just didn't expect my ui to slow to a crawl.
Delete any Bixby remapping app as well, known to cause many issues including unpredictable lag.

Stock camera crashes phone

Just got this phone 2 days ago after years of nexus /pixel usage. Great phone but the camera freezes my phone about half the time. After launching the camera my phone will become nonresponsive and I'll will have to power cycle it to regain access. Stock rom, stock camera app. This also happens with ported Google pixel cam app.
I've tried factory resetting, clearing cache, and clearing program data several times. Is this an intermittent hardware issue? Should I just return or try exchanging it?
Exactly the same here. On two occasions the phone became responsive again after a few minutes but now is the second time it hangs and I'll have to wait for the battery to drain down.
Did you flash anything? I thought it might be because I flashed a custom kernel, rooted it with Magisk. But I guess not.
Happens on stock Camera app + Google pixel app.
rooted with magisk. everything else stock, stock kernel as well. I was able to force reboot it (vol up + power). but it happens pretty consistently with any carmera app
Same problem here after rooting with Magisk. I don't seem to have the problem with the open camera app.
My front camera is not even functional for me. I can even use face unlock as it says that another system app is using it. Also I can not even swap camera to the front facing camera. I called support and hope to hear something from them on it
I unrooted (flashed stock boot image in fastboot) and the camera freeze issue seems to go away... Pretty strange bug tho
Never realized how many ads there were until you stop using adaway
Try out Blokada! It's an open source ad blocker that uses a VPN to filter out ads instead of he hosts method that AdAway does. It doesn't require root.
I used AdAway for years, but finally switched to Blokada because it's a lot more convenient. You can enable and disable it on the fly and add things to the whitelist when you find pages you actually want to view are being blocked. As you may have noticed in your usage, when that would happen with AdAway, you'd have to figure it out and then reboot because Android doesn't reload the hosts until rebooted.
Please see my thread https://forum.xda-developers.com/oneplus-6t/help/camera-settings-crashes-t3865560
cool ill check it out... right now using vanced youtube and ms edge browser which has built in adblock. seems faster than chrome
you notice any battery drain from blokada?
I don't. Technically, running a VPN should cause _some_ amount of battery drain, but it seems negligible. My battery usage didn't noticeably change when I started using it.
