[Q] Screen Problem. Help!

I've had my Nexus 4 16GB for almost a month with no problems.
I plugged in my phone and went to shower for 10 minutes.
When I came back, I turned on the screen, and now I have a constant dim flickering over my entire display!
I've restarted twice and the problem persists.
How can I determine if this is a software or hardware issue?
If it is a hardware issue, do I have to remove the root (done about a week or 2 ago) before I send it to Google for a replacement?

Likely software. Some other phones I've had have also had screen flicker. If you do RMA it and it turns on and boots you should probably unroot and relock the boot loader.

Try flashing another ROM and see what happens. (Make a android backup first). To send it back to Google you're going to need to revert back to stock.

Update for anyone who might get this problem randomly. I turned the phone of for a little while and then turned it back on and it was fine. I've since switched from stock to CM10.1, and it's still fine.

Strange, I've got the exact same issue right now... flickering is present in recovery/boot so I thought it maybe hardware failure.. will try CM10 instead of MCR once I've backed up! For reference:

Did you have something like this too? Did you wipe when to fix the issue?

That's not exactly what mine looked like, the flicker was more of a flashing of the entire screen. That very well could be a hardware issue, but don't take my word for it. I never flashed a ROM or wiped anything to fix the problem. I simply turned the phone off a few times for around 10 or 15 minutes each time, and I just didn't see any more flickering. Hope yours can be fixed this way too

Doesn't look like it, I left it off for about 6 hours, still pretty stuffed. This is definitely hardware... looks like my night just went from bad to worse. :/

Oh that sucks
Hopefully you can get a replacement quickly.
Good luck

Phone turned off by itself

Hi all
Hope someone can help with this problem.
Tonight my phone just randomly turned off. I wasn't doing anything strange..just texting. I sent a text and placed my phone down. Looked at it and hour and half later and it wasn't responding. I held down power and it powered on but noticed my battery dropped quite a bit.
I'm bone stock 4.2.2, no root and locked boot loader.

Mysteries like this one are not uncommon.
Text message couldn't be sent, phone kept re-trying, got hot, turned off?
Signal loss, connection derp, overheating, turned off?
Who knows. I'd lean towards overheating..

If it's only happened once, what's the issue? It could have restarted for a multitude of different reasons but if it's not doing it on a regular basis then it's not really an issue in my eyes.

Mine did this for the first time today after 2 and 1/2 months of flawless performance too. Really weird, wouldn't respond to any buttons,charger, or USB cable. No red flashing LED. Battery was at about 50%. Wasn't doing anything with it beforehand, it was asleep.
After about 15 minutes of nothing, it recognized the charger and booted back up.

I'm more concerned about the battery. Why the sudden drop off from 90% to 70%

I think the 4.2.2 OTA may have corrupted the battery stats file for some users.
I had a similar thing happen where it went from 30% then dropped to 2% after a simple reboot.
Based on my usage at that time, I should have had a lot less than 30%.
Now if your phone gets unusually HOT, you have bigger issues and may end up with the RED light of death

phone gets warm but not hot. usually when i'm watching a video it'll get warm.

My issue was different, no heat or battery issues. Was at about 50% when it blanked out and 48% by the time it came back.

If phone becomes hot, theres a defense mechanism in which our kernel will make phone run at lower clocks which eventually gets our phone into sleep of death. So try one thing. If ever ur phone gets hot, dnt lock the screen and keep it on a cold surface, and once it get cold, press the lock button. See the diff!!

Hopefully not! If you do, follow the guide in my signature.

just for good measure, i went back to bone stock 4.2.1 and installed the 4.2.2 update when it got pushed through and the same thing happened again. i didn't even install any apps - just what was in the factory google image. i was just lightly texting, locked my phone and looked at it a few mins later and it was off. this time my battery didn't change and i took notice of the temp of the phone and it was cool.
this only happened after the 4.2.2 update as for the couple of months of 4.2.1, i never had this issue. i've only had stock 4.2.2 for a little over a week.
i'm going back to stock 4.2.1 or maybe will try out a custom. if it does this on 4.2.1 stock, it's gotta be a h/w defect but i'm pretty confident it won't.
thx again all for your suggestions and help.

Battery going nuts?

Running aokp with stock kernel, also paranoid android before and it did this. Any help or ideas to fix these spikes? Battery reading has gone crazy and obviously it's not charging but it bumps up the battery level though

What the hell??? Ok, u have to charge the phonte till 100% and then delete the file:
Code:
data/system/[B]batterystats.bin[/B]
Use the phone normally for a couple of days and report if the problem persists.

Clear Dalvik + cache and let it charge to 100%. OR charge it while the phone is off and do a battery cycle.

Thanks guys. The batterystats.bin file didn't work, also it's a new fresh install of AOKP so the whole data partition got wiped before installing. I think the battery got fried because it's way too hot where I live and the phone heated some times way more than normal.
I'm trying the charge withouth powering on now to see if it cures the problem.

Battery cannot get fried at room temperature.Ok does the battery charge linearly?

With the phone powered off it didn't charge. If I turn it on it says 0% and then it ramps it up to 22 or any other value higher than what I think it really is. That's the spikes on the screenshot

Yes, I would say it's broken

Update: I opened the phone, cleaned the battery cable and reconnected it and it is working way better than when it was new. Battery definitely lasts longer

LG G2 Screen garbled / distorted

This suddenly happened on my phone this Eve of Christmas. It was never dropped, wet nor bent.. It just happened while I was trying out voicemate. I think this is not software related as it is the same when I'm in recovery mode. Sometimes the display is correct and is not garbled but after a few seconds of touching it it acts this way again, if I try to turn off the screen it goes away but returns immediately after. Sometimes the screen won't turn on but I can feel that it is actually on thru the vibration feedback it is giving when trying to press randomly in the screen. I'm still going to try to revert to stock Rom as I am on rayglobe and rooted in case I need to send it in for warranty. I have already reflashed the Rom but still the same.. I just can't believe this is happening hours before Christmas and a few days before the new year.. I'm sure repair services of LG will take time.. Coincidentally, last year when I was using Samsung S3, the motherboard of the phone broke down on New Year's Eve..
Any thoughts what part of the hardware is failing? And what else can I try to troubleshoot before bringing this is to repair? Appreciate your comments. Thank you!
Charles

guys any thoughts what caused this?

upon observation, this is more of a heat issue. if the unit is rested in a cold place it takes more time before the screen gets distorted like this but after a while of having the screen on it starts acting like this.. i hope LG repairs this fast!

Sent it for repair man,nothing else you can do as it seems.I wanted to ask if you had it modded or something,to see if there was something that caused it.But it seems the hardware is failing.

Definitely faulty hardware. Have it sent in for repairs. Looks like a faulty flex cable. Or it could be the main board though.

Terrible Battery Life

Hey guys. I know XDA is filled with battery threads, and I've done numerous searches around the forums and across the internet. Nothing seems to be helping me.
Recently, the battery life on my Nexus 4 hasn't been so great. I've attached a few screenshots of GSAM. Any ideas on what is causing the significant drain? I'm down 15% in 1 hour and have barely touched my phone. Using stock 4.4.2, rooted with some Xposed modules (none of which seem to correlate to being installed near the time of the battery life becoming crap).
Here is a dump from GSAM as well: https://www.dropbox.com/s/z6uo3q5059mcwhu/02-26-14.txt
Edit 2: After just over 4 hours, I'm down to 50% with a ton of wakelocks. This is the part that I can't find any helpful info about. Here's the new log: https://www.dropbox.com/s/tv01k9tbmo38gbv/02-26-14 2.txt
Edit: Trying to fix the images yet again:

You know, I haven't ever on this device. I had on my Samsung Captivate and Nexus S, but have yet to use any sort of battery calibration on my Nexus 4. And now that you mention it, I've had some strange behavior with going from 35% to 25% rapidly, rebooting, and then having it at 30%.
Do you think it's worth a shot? If so, any good apps for this? When I did it on old devices, I just used the CWM option to delete battery stats and then charged/discharged fully. Seems that TWRP (which I have installed) doesn't have this option.

Thanks a lot, hopefully this works!

what the app does it deletess batterystats.bin
but google already stated that its just placebo, this file is only for the batteryicon
thats why cwm removed it.
second those wakelocks are just seconds. so its normal
third. do you have any sync service?(skype,facebook,email, or even google) if so
try disabling temporaly
if dosent work you may wanna try the xposed + xposed module called disable critical shutdown
then wait till phone turns off and charge for minimum 8hours
if not
change rom/kernel
if still not
its your battery(if so, and you still have warranty, you can get an rma if you live in a google area or get money back if you live in a area where lg controls,or buy another battery

Hadn't read about it being a placebo, thanks for the info. I downloaded BBS and think the issue is actually the (common) msm_hsic_host issue. It had several hours today. I'm flashing Matr1x kernel right now, so we'll see if that takes care of the issue.

Well that pretty much clears that up, thanks!

Try going back to stock android and check the performance. It can be that one of the Xposed modules is causing you the problem.
