Unresponsive parts of screen? - Nexus S Q&A, Help & Troubleshooting

My phone sometime the lower portion becomes unresponsive and sometimes when in an app I can no longer scroll down it only allows scrolling left and right: even in apps like Gmail.
I'm using stock ROM, I'm tested the issue with several kernels but no result. The problem gods away when I lock the screen and unlock I again.

I have the exact same problem. Been trying different ROM:s and it's the same on everyone. I believe it's a hardware problem.

Yeah, how do I manage it?

Flash a different kernel. Glados, Matrix, Franco or stock.

Is this issue confirmed on everyone's device? I feel like calling up Samsung if it is indeed a hardware issue.
Anyone else confirm your screen gets erroneous and unresponsive on certain kernels?

This happens to me at completely stock.

Did you buy your device new? Is this a hardware defect? Can anyone confirm this happened on Gingerbread?

Same issue while on stock GB and ICS, stock kernel. Problem goes away when screen is locked.
On average it bugs me a few times a week when I'm typing. Might have happened many more times, but as locking the screen clears the problem away, it could have gone undetected.

Weird never experienced on my nexus s i've tried GB .. ICS and a whole bunch of ROM+ KERNEL combination my screen works perfect maybe it's only affecting a particular bunch of hand sets .. idk? :/

it happens to me every now and then, usually while typing. generally i have to turn it off completely to fix it, which really sucks.
GB 2.3.7 and whatever the last GB matrix kernal. nothing running over or under.

Ya I have the same issue but for be it only happens when I plug in a USB or auxiliary cable ..oddly not my headphones (klipsch s4)
I've been debating calling into Samsung but haven't had time! Has anyone had luck!?
Edit: I'm running stock 2.3.6 i9020a

Why does the G2x show the previous screen before the lock screen?

no, i am not new here, just had to change username.
yes, i have check EVERYWHERE for a solution to this problem.
Basically my g2x will show the previous screen i was o before it will show the lock patter screen. Say im on the facebook, and i lock my device, if i come back to it and unlock the device, for like 2 seconds it will show what ever page i was on last on facebook THEN go to the lock pattern screen.
is there anyway to fix this?
My Device:
G2x
gingerbread 2.3
not rooted (4 days old)
Came stocked with gingerbread 2.3
has being doing this since unboxed
Haven't had this issue since moving over to CM7...
Known issue no fix, other than trying a different rom. What really sux if you tap before the lockscreen comes up you fan bypass the lockscreen. Doesn't always work.I'm still on froyo, gb ....not impressed.
meh...
Haven't had this problem on weapon g2x. I have with stock though.
Happens to me too.
Stock Gingerbread Rom.

What version of Weapon are you running?

I've been wondering the same thing

Its because the lockscreen is an app and sometimes it lags to start up when you unlock your phone.
I thought it was part of the phones software.
Sent from my LG-P999 using XDA Premium App
I think it is because the GPU is turned off to save battery and the graphics ram is not being updated. The lag is the GPU starting back up. That screen is like a ghost image. I don't believe anyone who says they can click on an icon before the lockscreen comes up and bypass it. I would have to see a video to believe that.
Happens to me too. EB 1.07. Also, sometimes when I press the power button the lockscreen is bypassed. This happens once in a while.

Weapon 2.7 seems to have fixed the issue. It drove me crazy on stock and EB.
Any newer rom from development I don't experience this problem

Its a known problem with the G2x. Some custom roms and kernels help a bit. But its the main reason I'm ditching this phone. Its a great phone for those who don't suffer with this issue.

Luckily I've never had this problem ever. Apparently from what I've read around here and few other forums are that their are faulty devices and it takes a few replacements to get a good handset.
Also, maybe getting recent new made device would negate those bugs. Mine was manufactured 8/11/11 and not one bug what so ever.
Good Luck

Random reboots are almost always app related. What apps have you installed? I have been running the stock GB and versions of it with no problems whatsoever. Never had a reboot or any other problems.
This is a common issue with the G2x. When the phone came out a lot of people complained about it and got different phones but I suggest flashing a custom rom like Weapon G2x and it could help fix the problem. If that doesn't work replace it at tmobile or switch for a another phone.

blank screen / non responsive out of sleep mode

anybody else having this issue? Happens atleast once a week, requires removing the battery to reset it..
I have seen this issue posted on other phones, but not on the MT4GS
Did you recently flash the new radio....if so revert back because it was proved that the new radio was unstable without a specific kernel
Total stock rom... I did upgrade to latest sw this week. I will see if it continues
the stock software does seem to have that glitch, where the home screen will have nothing but your wallpaper... apps and widgets will be missing. i had that once on the new update, but i rebooted and it hasn't happened again.
Mine just did sleep if death because I have it OC'D to 1.7

Screen freeze on wake

I recently flashed weapon g2x rom. Everything was cool til I woke my phone and tried unlocking it but the screen was unresponsive. I do a battery pull phone starts up up and screen is fine. Screen goes to sleep so I wake it up and try sliding to unlock but its unresponsive. Please help. BTW I am not putting any blame on weapon rom Dev team.

Did you properly wipe before you flashed the ROM? Is this happening on a clean install? (No apps)?
Sent from my LG-P999 using xda premium
Followed the install instructions verbatim. BTW I was stock GB before flashing. Happened before I dloaded any apps. Now it freezes when making calls. When I take the phone away from mg ear the screen is unresponsive.

You might have a defective device. Does it tend to get hot whenever it locks up? How long have you had this issue for?
Sent from my LG-P999 using xda premium
Flashed the rom 3 days ago and issue started today. Had this phone for 3 months. Doesn't get hot or even noticeably warm. I got the go locker app with ics lockscreen. After i wake it up its unresponsive for about 30 seconds then the backlight dims and becomes responsive again. Weird. Maybe restore back to froyo(nandroid)? Thanks for your replies.

Try reformatting your phone, then flash again
Reformat? You mean wipe everything? Through cwm?

Yep that is what he means. If you were on Froyo you may need to do the update and get the current Baseband.
Okay I'll do that and see what happens. Thanks guys

Hey this may sound silly but if it's only the lockscreen not responding and you stating you are using the ics lockscreen, did you try with the default lockscreen to rule that out first?

Not silly at all. I tried the original lockscreen that came with weapon rom. I would wake the phone with no response but with go locker LS the screen responds after 30 seconds of unresponsiveness. Its weird but I don't think its a hardware issue. I'll post back after I restore back to Froyo. Thanks again guys
Sent from my LG-P999 using xda premium
Yeah i agree, don't think it's a hardware issue. Restoring back or trying another rom would be a good test. Another question..are you using setcpu or any other app with a screen off profile?
Edit: Went back to read all the symptoms again and i had a similar situation and it was because my phone could not handle the lower voltages on the min freq with a few kernels. Morfic upped the lower freq voltage on his kernel and it has been working perfectly since. Worth a try.
Try this one: ELPmax 20122011 (1.1GHz Battery Saver w/ voodoo sound)
Tried flashing kernel and phone froze on Trinity load screen. Restored to nandroid but no luck. Updated to stock GB but no luck. I'm starting to think might be a problem with proximity/ light sensor cause of how the phone freezes up after I pull the phone away from my face after a call. Guess I'll send it to Texas for warranty repair.
Thanks to those that tried helping.

Did you format the "system" before flashing the new rom? Weapon works with no issues for me. I would stay away from custom kernels for now, until you have isolated the issue.
I would suggest backing up your user apps using titanium backup and installing them one by one to find the issue. Let the phone run a while between installing each app. Maybe even reboot each time. Also try fix permissions.
I know nothing about Go Locker, but is sounds like that is a good place to start.
