Battery dying very quickly - what to do?

My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?

turn off your mobile data when not in use. This will save tremendous amounts of battery.

if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.

I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.

I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~

Could be a Rogue app running killing your battery or radios not updated like stated above.

I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.

Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk

Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.

In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

Log out of gtalk and latitude. Those two seem to kill battery.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps

Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.

We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

Actually,
some android users looked at the posting date, saw that the op hasn't updated in over 24 hours, wanted to complain about it, decided against it, posted quickly the most useful idea they had.
All that while doing real science.

Serious battery drain with minimum usage

Hi all,
The battery life of my 4month old SGS is becoming shorter every week! I can 'almost' last a work day (8 hours) with a fully charged battery and minimal use.
I had this problem also on the stock firmware, Darky's rom 8.x was a slight improvement (much faster tho!), Light-ning rom and Darky's rom 9.x.
Everyday I charge my battery untill it is full, when my alarm goes off it's already at 98% (it's still hooked up). When I'm in the train to school, my battery already dropped around 86% (being idle). I check some mobile websites, my e-mail and read some twitter messages.
Because I know services as Twitter (I'm using Tweetdeck) uses alot of resources and battery, so when I'm done looking I always shut down those programs. And I often do an 'end all' task in the 'System' app which I purchased from the market lately to monitor my battery.
During the day the only thing I do is check my mail and some websites, but not for long, mostly it would be around 5minutes or so. So WiFi is turned OFF, GPS is turned OFF, and only GMail synchronizes with default settings. So what's the deal? Is my battery slowly dieing because of oldness, or is there another problem?
Thanks in advance for helping me! You're doing a great job!
Sincerely yours,
S1GNZ

after flashing your custom roms of choice... did you ever do a battery calibration?
like let your phone drain till it dies on its own... turn it on againa nd let it die again to completely drain it to the point where u cant even turn it on.
Then plug your phone in to charge and let it charge to 100%. Keeping the phone plugged in turn on your phone into recovery. Then clear battery status.
Then reboot your phone into normal mode and let it continue charging till it says 100%. WHen you unplug your phone it SHOULD say 100% still.
This normally fix the problem but if you notice that your phone is dying quickly still then PM me.

One small advice,try logging out google talk,of-course if you are not on it much,it will give you at least 2-3 hrs more.
Also,there is already a thread active on this forum 'dont kill your phone
,give it a life' give that a read.
Mainly this battery drains are there because of apps doing sync. or polling.identify them and adjust settings.

I've been browsing these forums lately, and I've also come across a thread which advice is just the opposite and that you should NOT do this, any advice if that's true? And is it also true that deleting the batterystats helps?

Am I auto-logged in on Google talk? If so, how do I log myself out :$? So Google sync might drain it? (Mail, Agenda, Contacts?)
Thanks for the quick replies! I really appreciate it!

I am not 100% sure if you auto logged or not.I believe not but if not so , then open app,press menu/setting button on phone,select logout.also if you not intending to use data network,press power key till you see a menu turn off,data network,turn it on when you need it.These small things saves some power.
If you dont want to mess around with this little twiks then 'juice plotter' is the app for you.it will manage lots of things and defi. saves battery.
BTW based on your usage desc., I think I use it in similar way ...almost and yet phone makes ~2 days.

You of course wouldn't be doing this alot nor should you NEED to do this often. It's only something you do when you're experiencing what you currently are.
Personally I have no idea why anyone say u "Should NOT" do this.. it's not like you're altering anything hardware wise. It's mainly software and power usage aspects.
Like I said to each their own. Some people say custom roms are a "No-No" cuz it messes with the phone in more bads than good and some says stock roms are for noobs. You dont HAVE to try what I said, it's merely a suggestion of fix or methods that seems to solve the problems others have encountered.
Clearing the battery status pretty much resets it's counter to 100% and from there it will "calculate" the life of the battery from full to empty. It's a calibration thing.
Now on regards to usage, keep your data plan off and auto-sync off when you're not using it. Leave your wifi off and gps off as well.. pretty much keep anything you dont need off until you need it. Some samsung apps does a background run thing where it'll auto turn on and auto run in the background which drains ur battery quite badly. If you don't use goggle talk or samsung chat apps, there are many ways to remove them completely so it won't mess with your battery life

Simple you installed a rom with multiple posts on battery drain problem .
A rom that also tells you about battery drain problems /fix on its front page .

Okay! And you're right, it logs me on when I start the app. But I logged me out, just to be sure. I know about turning of the mobile data traffic, I'll see how much it saves. I think I came across juice plotter, but I'll look into it. Thanks!

Don't be offended by what I said! . I only wanted to make sure I'm doing the right thing, I appreciate your criticism though. I did what you said and fully drained my battery yesterday, kept it charging overnight, cleared the batterystats through recovery mode and at the moment it's charging till 100%. I will see if it helps!
And according to my usage, I have Wifi and GPS turned of as default. And because I reinstalled a new ROM inclusive data wipe I don't have much chat apps installed, maybe there are some default apps that don't show up in the 'System panel' app though?

Care to explain a bit further?
FYI, I installed these ROMS:
past: Stock firmware 2.2.1
past: Darky's ROM v8.0 Gingerbread edition
past: Light-ning ROM 2.2 (if I'm correct, it's probably the latest)
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?)
Can't thank you enough for the replies!
Sincerely yours,
S1GNZ

im having similar problems too. calibrating doesnt really make a difference.
i installed an app called task identifier which is brilliant it tell me whats happening when the phone is asleep. the only trouble is i dont understand what these processes are so i cant disable them.... is there any sort of app out there that completely logs / signs you out of every app ??
i have 108 apps (not including system apps) and its hard trying to eliminate the battery drainers

Care to explain a bit further?
As it says post lots of with battery problems big big percentage running Darky rom .
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?) You would have to ask on dARKY Post .
Look at Battery drain thread LAST POST OR SO MAY BE OF INTEREST .
I am of the opinion that if a rom breaks something then installing more roms will often not fix the problem . I prefer a blank completely wiped phone in such cases with no trace of any rom left on it .
jje

@azzledazzle 108 apps? really ????
I don't have that much on my PC!
I think we should start narrowing down which apps drain most juice. I've been using Advanced Task Killer just to narrow down a couple.
example:
Sound Hound - starts on its own
Facebook had an issue with notifications push, when disabled, it still sent notifications to my phone. But I think they fixed it in the latest version.
We could start adding versions to know which app is a 'juice drainer'

[Q] [SOLVED, kinda] Weird battery drain for no apparent reason

Hello all,
I own an international N9005.
Up until recently, I used the stock Samsung ROM with good battery life.
A couple of weeks ago, with no apparent reason, I started getting horrid battery life - in access of 10% drop -per hour- in idle (as opposed to 1-3%).
I removed more-or-less everything, disabled more-or-less everything but nothing seems to work.
Got root (there goes the warranty) tried looking for Wake-locks and nothing. The Note3 is 97% (!!!) awake even with everything disabled, and in the wake looks screen both user and kernel I only see 1-2 minutes (!).
Tried resetting the ROM, tried installing other custom ROMs (X-Note, Omega, etc). Nothing seems to work.
Currently I'm running Omera v20, with *zero* applications installed (including all the Google and Samsung applications beyond Google Playstore) and all external services (location, WIFI, et-al) disabled, my note 3 is still 95-99% awake, and the list of wake lockers is, errr, empty.
FWIW I'm ~100m from the nearest cell tower.
EDIT: According to battery meter, Android OS is keeping the phone up.
Any ideas?

Indexing your external SD maybe?
You could try the link in my sig and try again for your custom ROM.

First, thanks all for taking the time to answer.
I'm thinking about getting a new battery, but my gut feeling is that its not the source of amazing battery drain - ~20%/h while completely [!] idle (auto-sync/location/etc completely off).
I've attaching /d/wakeup_source in excel format sorted by count and total time - in-case someone has any idea what's completely broken.
As far as I can see, qpnp-vadc-ebd30a00, sec-battery-monitor, mmc0:0001:2 are the main culprits.
nicholaschum,
Before I attempt a complete wipe (as opposed to the normal wipe data / cache), how can I detect if someone is indexing my sdcard? (which may account for the mmc0:0001:2 in the wake lock dump).
- Gilboa

I know this is a long shot but try turning off developer options if you have it turned on(especially force gpu rendering). Somehow I found out that when I turned it on and the screen is idle. I get a battery drain. Not as big as yours. But not really sure because if I use the phone, the battery is actually pretty great(an hour of screen time is about 10% even more with internet apps like facebook youtube chrome etc.).
Clear cache. I know this is too common but it actually works for a lot of people.
Lastly, try airplane mode overnight and see if it doesn't drain. It might be your network that is causing the drain.

Hi, basically just check your phone using BBS (BetterBatteryStats), and see which individual process is eating up your battery.

Already installed - together with WakeLockDetector.
Short update, out of pure desperation I completely wiped the phone (including sdcard), tried installing stock ROM and, err, Odin failed. Managed to get CWM running again and installed the latest CM nightly.
...
As weird as it sounds, going from NF4 based ROMs (including stock) to CM nightly dropped to idle battery usage to ~2-6%/h, a huge drop from ~20%/h.
I'll update and mark resolved if this situation holds (crosses fingers).

I heard there were problems with NF4 battery. But I haven't been on TW since ND4. No matter what on Note 3 TW the battery sucks. AOSP is great. But actually S5 port has the best battery.

Solved, at least for now.

I use Nova (and not TW)
Either way, latest nightly seems to solve the battery drain problem completely - using the same Nova and system configuration (widgets, active syncs, etc). Currently I'm at ~1.5-0.8%/h when idle with no issues going into deep sleep.
Seems that my specific model really dislikes NF4.
Thanks again for trying to help.

This thread has been quite helpful as I was suffering with a Battery Drain after the NF4 Upgrade.
Planning to go back to ND5, which was the last stable version.

I was thinking about doing the same, but in the CM 11 runs circles around both NF4 (duh!) and my previous ROM (not sure which revision it was) - plus I can actually get 2 days of standby time, even with the old batteries, so I'll stick with CM 11 for now.

Battery Life Tips and Tricks Thread

I've noticed this phone has hit or miss battery life depending on what you have installed, greenified and frozen. I thought it would be a good idea to create a thread where everyone could share their battery life tips and tricks on this phone.
Below I posted what I have done to maximize battery life. I have not rooted my phone yet, so none of the below tips require root.
I disabled all bloatware apps that came with the phone. I did not disable any of the Asus applications.
I utilize the Asus autostart manger and denied auto start to all my applications except music applications, messenger applications, and google photo sync.

battery sucks. drain to much.

Just use until you have 5% free battery, this should make at least your day
With Android OS taking so much thanks to lollipop, there is not a lot to hope.

We wont see a good battery improvement until we get 5.1
Luckily, that is in the future for this device acc. to Asus.

Since the issue seems to primarily be Android os draining the battery I don't think most battery saving measures will make a difference. We will just have to wait for an update

When I was looking at the phone reviews people were claiming 8 hours screen on time, I can barely get 2 hours screen on time.
The problem I'm having is that the phone never goes to sleep and is constantly awake. Has anyone else seen this issue?

I had the same problem after the latest update, no deepsleep in BetterBatteryStats (I'm rooted), I wiped everything and now it goes to deepsleep.

Which firmware version are you on. I've wiped the phone once already, did you clear any caches? It's driving me mad

I'm on 2.18.40.12 (ZE551ML of course), I restored the phone from backup & restore in settings (It may take 30 minutes or more). Before restoring I had 45+% of Android OS during the night, now 20% more or less, but, as said, also in BBS I can see deepsleep in frequencies.

Someone posted on Zentalk to turn off remote lock and scan for security threats in google settings. Not sure if it helps or not.

I wiped my phone yesterday and restored back up like you suggested and it seams to have sorted out my wake lock issue. I wonder why that is?

Glad you solved, but don't know why, maybe they are working hard on the firmware and there are lot of changes that can cause problem, maybe we have to wipe after every update, Intel processor and Lollipop are so unstable right now!

Ok so this is my battery with a normal day of use... Tomorrow ill show the results with your sugestions. My normal days have gsm calls(normal phone calls) whasapp (chat) youtube, twich, game like plant vs zombies 2, look at gmail, surfing internet, taking pics like 25 today.
I notice that battery drains a lot more while photo app open.
I use doble sim as you can see

If you want to test app battery drain, try GSAM Battery Monitor, or for some extra functionality the Pro version. Also very useful to determine what is causing wakelocks when you run into them.

Thank u sir thats a good one

Everyone is always wondering about Android using the most battery. Without doing some in depth debugging and tracing I would guess Houdini falls under Android. Because the ZenFone 2 uses the Intel processor a binary conversion for ARM instructions takes place with Houdini. More than likely you have a lot of apps native for ARM.

Force closing asus support app and zenui services app from apps setting gives me good amount of battery boost. Apart I have also disabled google books, movies, plus etc. I don't know if its placebo effect but someone can try and confirm. These app tend to restart at times so if you feel the battery decreasing at high rates again, make sure you force close them again.
Roughly speaking, I tend to get 3-5 min per percentage of screen on time with this which totals to 5 to 6 hrs on SOT on continous usage. Without the apps being force closed, I barely get 2min/%. The usage scenarios are normal web browsing, chats etc. This is using mobile data. It gets even better with wifi.
Try and let me know if this helps.

Maybe I don't use my phone as much as other people. I posted this last night on another forum. My phone was unplugged at 07:00, It's now 21:00. I have 80% battery left and the battery monitor shows 3 days left
I have received email, 3 phone calls and text messages. I checked Twitter a couple of times with the browser. I have read Google News a couple of times and played GSN Casino for about 20 minutes.
In Auto Start Manager I turned off Docs, Sheets, Skype, Slides, Translate, Amazon Kindle, Data Transfer and Web Storage. Everything else is Allow, but I have no social networking applications installed.

Its looks like battery life is a right mixed bag. At the start of the week I was suffering wake lock issue, my phone wouldn't go into deep sleep and was constantly awake. I wiped and restored from backup which seams to fix the issue.
Got up this morning and it looks like the wake lock issue is back. I don't know what to do to fix it.
Feel like giving up on the phone and sending it back if I can

GApps on Rooted LG V20

Does anybody know if we are able to flash any other versions of GApps on the rooted LG V20?
My V20 is from AT&T and since day one it has had terrible battery life. Where I was able to use my Note7 or Droid Turbo all day and still have battery left, the V20 eats the battery charge like Sally Struthers in a See's Candy warehouse. I mean, I have to charge this thing at least 2 times a day when I use it to search the web or any battery intensive purposes. I never had this problem on any other phone. I have been trying to find ways to improve my battery. I used Rom Toolbox Pro to disable all kinds of stuff, and it worked great, until my phone started Grand Mal seizing giving me the Google Play Services has to close notifications, which I then had to factory reset just to get my phone working properly again.
I would like to try flashing a minimal version of GApps that pretty much just has the play store and play store services. Are we able to do this on our V20's without having any issues? If you have any input at all I would really appreciate it.

IMHO it must be an app or two you have installed draining your battery like that. On a full charge I can a whole day and a little in to the next. I am a heavy user too. Are you blasting the brightness at 100% all the time? If so auto brightness will help a little. Go in to setting and see what is using that much drain

I was thinking it might be something I installed, as well. But I can't seem to pinpoint any apps that might be causing the battery drain. I keep the screen on auto brightness like you mentioned so it shouldn't be the screen. GSam almost always shows the Android System and Kernel (Android OS) at the top of the list of battery-draining apps. I love the phone, I just cannot figure out what is going on. I mean, I am not doing anything different than I have on my previous phones, and the V20 seems to be working fine. I thought maybe it is something with Nougat. I will gladly post some pics of app usage or data if it might help figure this problem out.

What rom are you on? Are you on stock white theme? I'm running a dark theme, which can help save a little juice. I'm also running as many team blackout apps as I can (many Google apps) to avoid all the whiteness. Just throwing out some ideas.

Interesting! I have never heard of Team Blackout Apps, they look pretty nice! Yes, I am on the stock ROM just the way it comes. I haven't changed anything at all. I have barely installed any apps just to see if I can find what is causing the battery to drain. Are there any other ROMs that work with the AT&T variant of the LG V20? It seems like they haven't made any yet for the AT&T V20. I am still waiting for Xposed to be released that is compatible with nougat so I can use Amplify.

I don't think there are any roms for AT&T variant atm. I did see an AT&T user flashed the stock deodexed rom by tilde88 in rom section. Not sure of all the details though. I'm assuming you would lose some functionality...would need to flash stock kernel as well.

What is your leading source of battery drain under system usage?

Yeah definitely, I think it is a little bit too early, for me at least, to expetiment with a deodexed ROM. But I know there will be some awesome developments coming out soon. I was so happy to see that a root was figured out for the V20 so quickly after it was released. Until then, I will keep experimenting with the stock ROM.

Hi Swizzle82, thank you for the reply. It is kind of difficult for me to pinpoint what the leading source of battery drain is because the apps seem to bunch all detected processes and wakelocks together. I know that Call Services & Android System show up on top a lot of the time, but since I factory reset the phone today, the stats are minimal compared to what I previously had. WeChat also uses resources, but I used that app all the time on my Note7 and previous phones, even more than I do now, and it never caused a problem. I attached some screenshots from GSam, BetterBatteryStats, Wakelock Detector, and CPU Spy Reloaded., I don't know if they will help, but just switching between those few apps and taking some screenshots over the span of 6 minutes, my battery percentage dropped from 79% to 76%.

I had android system for a while killing me.. I factory reset and setup every app one by one with no data transfer or anything. Installed every app like it's first install. I charged it til it reached 100 percent, with the phone plugged in, I went to data/system/batterystars.bin and deleted that file and rebooted. It was a long process but it hasn't been an issue since. This was when the phone first came out last month. Never knew which apps data it was but it is gone now.

That sounds like a good idea to try. I will do this today since I already factory reset it yesterday. I would rather do it now before I get further into using it again. I have not heard about this until you mentioned it so maybe there is an issue with app transfers with the V20 causing it. The battery does seem to drain less than before, but it seems like there are still some issues. Thank you for the suggestion!

If you followed did the dirtysanta method, make sure you flash the Konverged kernel for the H918. Or Tilde88's 5.1 kernel for the H918. It worked wonders on improving battery life. Also make sure you disable Lookout - that drains a lot of battery it seemed to me at least. I usually get about a day and a half of battery life when I use my normal amount (which is honestly quite a bit).

Okay, thanks for letting me know! I have not even looked at those kernels thinking they weren't cross compatible with H910. I am going to try it right now with the dirtysanta method. I will disable Lookout, as well. There are a ton of apps that I never use that drain the battery. I will let you know how it goes :good:

No, I had the Note7 before getting the LG V20. Before that I had a Note 4 and a Droid Turbo. This is my first LG phone and I really do love it. I actually like it more than the Note7, the only problem I have is the battery. I do think that factory resetting and manually installing the apps instead of restoring them will help, and using the Konverged kernel seems promising, from what I am reading.

Yup I always start fresh and install apps manually anytime I reset my phone. I think it's always nice to start fresh - even if it is sometimes a bit inconvenient to go through all the apps you've installed and choosing which ones to install. Hopefully you get it all sorted out!

Okay, I just factory reset the phone, rooted it with DirtySanta, and flashed the Konverged kernel and the phone is NOTICEABLY faster and smoother! This is great! Each time I reset the phone, it had noticeable lag. I just figured it would go away over time, which it did, and that it was because it had to load and download everything since it was fresh. But with the Konverged kernel, it has none of the lag and is silky smooth! Time to manually install the apps I want and disable some stuff I don't need. I will update you guys after I see how the battery is with the new setup Thanks a lot for your help, I really appreciate all the input!:good:

I need your help! I changed the screen cover sensor to off not realizing that I would not be able to turn off the static after rebooting my phone since the sensor is off. Would somebody please post a few screenshots showing how to navigate to the screen sensor settings so I can tap my way there and turn it back on? I am trying but there is no way to tell where to tap with all the static. Thank you!
Nevermind, I fixed it! I finally navigated to the second screen settings and turned it off when the screen is off and that got rid of the static after I turned the screen off then on again. Note to self, never do that again LOL.

Wow I'm fairly impressed you managed to do all that with the static screen haha - glad to hear it worked out for you in the end.

Get me your stock system.img and boot.img, and I'll make you a modded ROM with a custom kernel!

Haha yeah, I never knew something like that could cause such a huge problem. Now I can't seem to find what I did to cause that in the first place. I have been looking through all of the settings and can't seem to find anything that affects the proximity sensor. On top of that, the screen rotation stopped working, it will not rotate when I turn the phone to the side to type. I have toggled all of the motion and second screen settings, calibrated the motion sensor, and nothing is affecting it. When I turn the main screen off, the sensor does not shut off the second screen when I cover it with my finger, and the phone does not recognize when I rotate the screen. I am kind of at a loss on how to fix it.
