Crazy Backbutton

Hello,
my Backbutton activates itself. While I am watching Videos, or whatever I do it stops shining and I am out of every application I'm using. After about half a minute it's shining again and I can use it normally. It's like pushing the button multiple times. Does anyone has an idea how to fix it? I tried different roms but it looks like an hardware failure to me.

Happened to me as well it is an issue sometimes with samsung but covered under warranty bring it in to sprint
Hit the thanks button if i helped

Sending it back for support is not an option for me. I imported my device from the US to Germany. The support at Samsung Germany told me that they are not responsible for AMOLED devices.
My second problem ist that my IMEI is crashed since I flashed a rom where the dev made a little mistake. So Samsung won't give me any support.
I thought about changing the display but the price for a new one is about 190 Euro. Way too much... I can assemble and disassemble the device but I think that cleaning the device will not solve the problem.
Any suggestions?

It has nothing to do with the display though.
That's likely the part failing:

Verify that the one you currently have isn't simply not connected right.

Thank you. I will have a look if the part is not right connected.
Maybe I have to replace it. But in that case 25 Euro are much cheaper than 190.

This happened to me once. A day later my display completely died. I could turn on my phone, answer calls, etc the touchscreen worked, but I couldnt see anything. I had to get a new one..

I had this problem too.
I flashed a different radio, and boom!! issue resolved

I occasionally get this too. It only comes up when I'm using cm/cm based kernels though, very odd. I'm on matrix right now and it seems to Beowulf, anybody have some tips or suggestions?

I tried a different kernel and it looks like the problem is solved. I know that you should not count your chickens before they are hatched. But I really think that the kernel was the problem.
Anyway, I am just happy that my phone is working properly.
And now I am waiting for jellybean.

What kernel were you using?

It was not the Kernel!
Changing the radio solved the problem.

I don't see how the kernel would have anything to do with the backbutton. Although if it worked out then hey that's awesome. Amazing how much I have learned by reading the forums on this site.:victory:

Just clean off the the backbutton, and maybe it will stop or you have a software bug.

[Q] Screen Flicker?

I haven't seen anything else posted, but I wanted to see is anyone is having the same issue as I am.
Basically, I'm getting what I think are row's of pixels flickering in the area of the screen that are gray.
Here is a quick vid trying to capture it. I can't post videos because I have less than 10 post, you are going to have to trust me for now...
I've also used the dead pixel finder app...everything looks good until I change over to a gray screen, if I stare at it, I can see the flicker...
I first noticed it when I flash Franco r10 (which is what I was on in the video). When I flash back to stock kernel or Bricked, it's much better. But now that I know it is there, I can still see it.
Anyone else having this issue? is there a fix or should I just send it back?
If it matters... LG-D820 White, 32gb

I'm guessing I'm alone with this issue and that it is a hardware problem. :thumbdown:

I haven't noticed anything on mine, but I haven't flashed anything yet. Did you notice the flicker before you flashed the first time?

No I didn't notice anything until I flashed r10. But now that I'm looking for it, I can see it on stock and bricked ever so slightly.
I could live with it on the stock colors, but if this is hardware, I worry that it is going to get worse and not better over time.

I have the same issue and saw it as soon as I flashed franco kernel. Noticed that if you set brightness to 100% it will slowly stabilize but will still come back when lowing brightness. I called for an RMA, but cannot reproduce it as obviously on stock, so i'm also lost as to what it could be.
What did you end up doing?

On mine, I could see it on Stock colors, just not as bad... I returned mine on rma....
I recommend getting the app called display tester.
I don't have enough post for a proper link.
https:// play.google.com /store/apps/details?id=com.gombosdev. displaytester
Look for a bad pixel and go under the banding section for reason for rma.
My new phone didn't have any of the flicker /banding that my old phone did.
Good luck..

Sorry to bring back an old thread but I just noticed this not too long ago and didn't want to open a new thread. I noticed it while I was on stock first and thought flashing something might fix it. I've had mine since the beginning of November. Is the best option just to RMA it?
Sent from my Nexus 5 using Tapatalk

can you use a SlimPort cable or chromecast to mirror the screen to a TV and see if the flicker still happens?
So you'll know if the problem is in GPU or screen?!

Anyone seen this before??

I was going through my wallpapers and I've noticed that one of the wallpapers has been cropped by default and I can't get it to display right.
I've tried to reboot the phone but that didn't help.
Any one knows how to get this wallpaper back to normal size besides factory reset?

Mine is like that too, I wonder if the recent launcher update did that?

I just checked and mine is the same way. It definitely happened after the update because literally the day before I updated I changed my wallpaper and now I can't even adjust it.

Nooppee hahaha, you can probably redownload the stock photo and then just set a wallpaper from your photos

This was an issue a year or so ago also, after one of the Google Services updates.

Nexus 5 lagging

Going through some threads it seems most dont experience any lag so im wondering what the problem could be in my case i sometimes notice slight lags when opening/closing app drawer, switching to quick settings, opening/closing apps (turned off animations so not really a problem now) and a few other instances is this normal? it got quite bad so i unrooted it and locked bootloader then unlocked and re-rooted and at the moment i am on stock rom, stock launcher and faux123 stable mainline 11 kernel

Glad I'm not the only one. Do the apps include any of the following: Timely, YouTube?

I've been doing some browsing here and it looks like your not alone. Maybe next update will fix this for Android in general or that app.

hopefully it is something that an android update will fix soon as its not just apps for me its everywhere but not all the time, i was wondering if its the custom kernel im using? Hopefully it isn't as i cant change the gamma values in stock kernel so that is the main reason for me flashing a custom one

Doubt it's your kernel. I'm running stock and suffering as well :/ It could also be a defect, some run fine others don't. Same with the same speaker issue, some newer owners especially the red ones claim it sounds better as the old ones.

Try switching to ART runtime, it seems to be much smoother. Im using Franco's kernel with a lot of downgrading in setup and yet I don't experience lags.

I did think about switching to ART but to be honest i dont want to lose anything in terms of stability but hopefully soon it will become part of an update so if lag is normal on dalvik now i dont mind waiting i just wanted to see if its normal or im doing something wrong

I'm sure that the problem could be around some settings with faux kernel. I use it too but recommended settings foe nexus 5 seem to cause some lag for everyone as it's more for saving battery life...
You might nee to play with some settings there Like governor and Hotplug.

I have already turned off animations for transition animation scales but when i turned off the rest it looked weird so turned them back on, i didn't understand 'Sorry cut the last 2out the 3 to 0ff and speed first'

Another thing i forgot to mention is when i unrooted/went back to stock i let the apps auto update and straight after i noticed there was lag when opening app drawer so i uninstalled all the updates and it fixed itself has anyone else had this happen? I have had to set the apps to never auto update now

Installing updates from Play doesn`t make the phone laggy unless there is a problem with an app or some apps. Rebooting after installing updates clears most problems most of the time.

Install BetterBatteryStatts for unusual app behaviour which is most likely the reason of your phone lagging.

I downloaded betterbatterystats but it isn't showing me anything regarding apps only the device wake/sleep stats etc

Screen bouncing 😢

I have recently beginning to have a screen bouncing issue. Seems to be getting worse. Started about 5 days ago.
Tried factory reset, safe mode and tried android M but still the same.
What is causing this maybe? Don't want to get a new phone as still loving this. Longest phone I've ever had.
Here's a video of what I mean https://youtu.be/qtsouaLdqgc
