Twitching screen

I've noticed an annoying bug on my touch screen on my sgs2, and wondered if anyone else has this problem.
Basically, the problem seems to be able to be reproduced by, for example, scrolling the settings menu with your finger, then stopping, but leaving your finger pressed on the screen, as if you were holding it still with your finger. Mine seems to be twitching and moving around slightly, it doesn't stay still.
Not a big deal you may think... But if your an angry birds player or a player of any game or app that requires precision movements then this is an annoying bug.
I'm on ke1. Can anyone else try this for me? Cheers.

Mine had stopped doing it now... But, I have noticed it before, so it seems I have an intermittent problem / fault / bug. Anyway, can everyone post here if they notice this... It happens in every app I've used that involves scrolling.

Nope, mine doesn't do this. And I'm glad about it! Sucks man, trey flashing a different rom.

Are you using a non samsung charger?
This used to be a charger problem, should work flawlessly with the charger thats provided with the phone

Could be a glitch in the motion setting, if you go to settings>motion and test the one where you put you finger on the screen and tilt the phone and the background moves.

Depends on quality of electric supply out of socket as well as which charger in my experience.

Mine was on charge when it happened, and it still happened some time after, but it stopped soon after.
3rd party charger (I leave my sammy one at home, I'm just using a spare for work)....
Could be that then?

Random "click" noise

Every now and then, when opening an app or using the system buttons at the bottom, a very short "click" noise comes from the speaker. I have my N4 on silent/vibrate all the time and it is not an operating system noise that's meant to be there because its random. The best way to describe it is that it seems like the phone is "accidentally" starting to play a sound then stopping because its realised its in silent mode.
Anyone else getting this? Views on this problem?
(It happened again as I was typing this, so it happens through the the keyboard key presses as well)

Media Volume
Maybe you have to turn down the media volume.

I don't have a nexus 4, but I do get that random click noise on my incredible s as well, and from many different roms. I am not sure what it is, though.

Key press noise in settings turn it off may stop it the Gnex had this issue and still does

I get that click noise occasionally on my HTC HD2.
Running PACMAN 4.1.2 Jellybean at the moment.

I had this issue as well. I just turned off touch sounds and all is well.
I should note that I have keyboard sounds enabled and I do not experience the random clicking noise.
It seems to be isolated to the enabling of touch sounds, whether on vibrate or any audible volume.

Could it possibly be the autofocus that people are taking about?

It does sound like that . mine sounds loose when I tap that back glass everything seems to be working OK and not sure if I'll let it bug me just yet

I have the autofocus rattle issue as well. But I rarely if ever would shake my phone like that.
At this point I am just grateful that I got my phone, let alone got my phone earlier than projected. There are a lot of people that would love to hear the rattling of the autofocus on their N4.

Power Management
Ok... I think this is correct,
The audio chip like most other IC's are entering power saving mode milliseconds after you hear any audio so the small click is the powering up and down of the audio hardware... Many phones do this and many people don't notice it.
It's quite normal but if you have very good hearing it might bother some more then others.

It seems like a touch sound issue.
Make sure you've got touch sounds turned off by going:
Settings > Sound > Touch Sounds (disable the checkbox)

Annoying touchscreen problem

Hey guys,
So my N7 seems to have gone crazy. I can't even type, scroll, zoom in/out or swipe or do anything on my nexus 7. I enabled the "see screen touches" option in settings ...
The problem is that it get this random touches on my screen. And when I actually touch the screen it does not record my touches... Sometimes I'm watching a video
and it will randomly pause it because it recorded a touch..
Any of u heard of this issue??
I was trying to type it on my N7 but I couldn't get past the title for the thread :banghead:
Thanks I'm advance

Nexus 4 Bugs

I want to ask if anybody has similar bugs to a non-rooted, locked, stock nexus 4 on 4.2.2 and would like to know on how to fix them. I have factory reset the phone and always seem to get the same results. I don't mind these little bugs, but they are making me want to root my phone.
1. While listening to Google music, I would try to unlock my phone and Google music screen widget would flicker and shake and make unlocking difficult I provided the picture on the attachment.
2. Another bug while still listening to Google music; it would dim more than normally it would in a shorter amount of time on lock screen.
3. Almost every time I open YouTube, the YouTube window animation flickers.
4. Battery drops 2-5% when the phone is rebooted.
5. Phone battery % drops after being fully charged and unplugged.
Sent from my Nexus 4 using xda app-developers app

4 and 5 are caused by a slightly wrong calibrated battery if you reset the calibration files (here is a tut somewhere) or just do only full cycles for a few weeks this shouldn't be a problem because it is just a displayed drop I think I'm rooted and don't listen much to Google music so no comment to 1 and 2.
3 isn't known to me.
Just a quick answer haha
Gesendet von meinem Nexus 4 mit Tapatalk 4 Beta

Thank you, I'm going to look on how to properly calibrate the battery. These little bugs can get frustrating at times.
Sent from my Nexus 4 using xda app-developers app

Don't know about 1 and 2.
3) The youtube app is a buggy piece of sh*t, so I wouldn't sweat it too much.
4) The battery percentage drop on rebooting has occured on every ROM I tried so far, so I don't really care. Well, maybe not 5%, but 1-2% is normal for me.
5) Happens to me occasionally, I don't really mind if it drops to 99% straight away, it's only correct. 100% would mean that your battery is perfectly fully charged. When you unplug it, some tiny (seriously) amount of power is being used due to the fact that your screen turns on, right?
Try cleaning the app data and cache for Play Music and Youtube (settings > apps) and see if it gives any result.

Thank you for helping. I forgot to mention another bug that is probably the worst. When receiving a phone call, I pick up the phone and the screen turns off. I try to turn the screen on and it doesn't respond. This bug has made me miss calls various times.

Mh well your on/off presses sometimes interfere with the proximity sensor on your phone this "issue" sometimes causes wild screen on/off during call because I click the button but the screen was already turning on because I no more held it next to my ear so it turns off again so I click again to turn on but hold the phone to my ear shortly to check whether the other person is still in call so proximity sensor reacts.... Repeat n-times. But that doesn't sound like your problem. Could you describe it more specific?

When receiving a phone call, I pick it up the phone and the screen turns off and doesn't respond to the power button. I have to tilt the phone until it turns on and until I get a chance to answer the call. Proximity sensor/s does sound to be the cause of this. Any way to fix this?
Sent from my Nexus 4 using xda app-developers app

Phew I don't think so... But changing habits... I'm working on a solution for my random clicking but I think the only way to solve that is to give the phone more time to react before pressing power button because it'll turn screen on/off as you would like it to but it needs a short period of time for that

Hopefully Android 4.3 fixes some of these bugs. The Nexus 4 Lg adapter was garbage, I dropped it once and after that it stopped working.

They said to clear cache/data & uninstall updates. Then update.
It did not work. I told them & they said they will Look into fixing this issue in a update later on.
Sent from my Nexus 4 using xda premium

Yeah, uninstalling and updating apps doesn't work. I've been doing that since the longest and no fix. Factory resetting or even flashing stock doesn't seem to fix these bugs either. Hopefully later on they find a solution. I didn't mind these bugs at first, but after a while, it got frustrating.

1. While listening to Google music, I would try to unlock my phone and Google music screen widget would flicker and shake and make unlocking difficult I provided the picture on the attachment. Don't use the lockescreen and/or the music app. Google play music works fine on my end.
2. Another bug while still listening to Google music; it would dim more than normally it would in a shorter amount of time on lock screen.
Don't notice this because I always sleep the phone manually after choosing music.
3. Almost every time I open YouTube, the YouTube window animation flickers.
Never have experienced this.
4. Battery drops 2-5% when the phone is rebooted.
This can happen, yes. Stop rebooting so much.
5. Phone battery % drops after being fully charged and unplugged.
This happens about 95% of the time. Nothing to worry about.

Thanks for your reply. For the Google Music apk, I don't use any lock screen widget. When I listen to the music and try to unlock it, that's when it gets buggy. Either the widget shakes or the screen dims more than normally it would. I only reboot I once a day every morning in order to reduce lag and refresh the system.

I guess I don't know what you mean with the music app. What Rom are you on?
Sent from my Nexus 4

I'm on stock rom, unrooted and locked. I was on cyanognemod, unofficial miui, and decided to go back to stock. I have enjoyed stock until bugs started happening. When I listen to Google Play Music; there are times when I turn my phone on and try to unlock the screen, the Google Music widget shakes and makes it difficult to unlock.

Found another bug. Not annoying but its just there. When applying a stock wallpaper and you immediately scroll left or right, you get this result.

May be it's just the universe trolling you saying "one does not simply not root a nexus".
Yes most of the bugs you mentioned are present and they are fixed in most of the custom ROMs.
