[Q] G2 Screen Issues

Hello,
I've been having touch screen issues lately, since i rooted and switched to CM 6.1 a couple of weeks ago. The screen will work perfectly for a little while, but will inevitably stop responding. I'm using launcherpro, though i don't believe that's the issue- it happens regardless of which launcher I'm running (I've tried others and experienced the same issue. The optical scroll pad will still "sort of" work- better than the screen (which will respond to the occasional touch after the problem begins, but barely does). If I reboot, the problem will usually go away for a while again, but will recur. I wind up needing to fix the issue once or twice a day. I don't think it's a hardware problem because the reset fixes it, so I assume it is then software. Also, i don't remember having this problem with the stock rom. Has anyone else experienced this, or does anyone have any ideas?
Thanks!

Dunno how useful this will be, but have you tried reflashing CM?

Same problem here. But I've noticed sometimes if I'm using the phone not in my hand (on car dock or just on table) this problem seems to happen more...but when I hold it in my palm then works fine.
But sometimes it just becomes unresponsive. Am running virtous's rom on my g2. But I can remember having the same issue when running cm on my g1 days too. Reboot always fixed it, just gets annoying.
Anyone have fixes to this? Thanks!!

I personally use GV 7 or sparksmod and. Never had a problem, these are the best roms I think for this phone.

Been having this exact problem for weeks now. And I believe it is a hardware problem, probably some sort of short in one of the ribbon cables or the digitizer itself. Occasionally, actually 85% of the time I'd try to open an apparently and the phone would act if I held my finger down and then the apparently icon gets selected...very annoying cus it happens over and over a couple times, all I can do is keep trying until it does what its supposed to. Also with the on screen keyboard when I'm texting it'll act like I'm holding down on one of the letters and keeps bringing up the special characters to that letter...or ill tap delete to delete a spelling error and it'll end up holding it down and deleting my whole damn text and I can't stop it.
At first when this first started happening I could simply tap the screen and it would stop the crap it was doing and work fine. As time went on I noticed I kept having to hit it harder and harder for it to correct it. Wellllll guess what? Last night it was acting up horribly and I slammed my closed hand against it while it was on the desk and it cracked the LCD screen and now the phone is completely useless, even though the outer touchscreen is perfectly fine.
The restarting of the phone also usually fixed it for me as well but only for a few minutes.. which also makes me think its a short because after the phone is turned off whatever part is shorting out, that circuit is closed and just takes time until you press on the screen in whatever spot to cause the two parts to touch and create the short all over again.
Anyways that's my story...just don't get angry and slam down on the screen lol. This is my 2nd G2 and I'm tired of it, probably just going to get a nexus s or just go back to the nexus one, atleast it was reliable.

if you open the battery cover u can see that there are connectors that closes the whole circuit, so when u are holding the phone the back cover works like a grounding area that makes the screen responce to your touch. Acapacitive screen works like this: when you touch in any area on the screen, you simply are breaking the electrical field that the screen has, the screen "feels" where u break it and tells the operating system.
the electrical field depends on the human body a bit to make the circuit complete, so when u touch the metal parts of the phone, the screen works like it is designed.

"Ghost Touches"

Hey All-
I searched for this with the assumption that with all the N7 screen issues there would be others experiencing this but I was not able to find much of any help.
----
My N7 is registering touches without me making contact with the screen. It is always in the same location. When the keyboard is up, it is where the letter 'D' is located. If I pass my finger directly overhead, or often times, even near to, the 'D' button, the tablet registers it as a touch. I can make the tablet register a touch with my finger as far as 1/4'' away from the screen surface. As you may imagine, this makes typing near impossible. As I pass over the letter 'D' to access other letters, it registers 'D' everytime.
I have tried other keyboards and the problem persists. It isn't necessarily over the same letter (due to differing keyboard layouts) but it is always in the same location on the screen.
I popped the back cover off and tightened/loosened screws to no avail. Turning the screen off and then back on does not help as it seems to do with some of the other screen issues that others are experiencing. The one thing I have found to strangely help is pushing on the screen in the affected location with extremely firm pressure; in essence squishing the s*** out of it. When I do this, the screen will behave better (it will still ghost touch in the area but my finger must be very close to the screen) for a period of time before reverting to misbehavior.
--
Has anyone else experienced something of this sort? I am currently running stock/rooted/unlocked; It seems to be a hardware issue so I don't think another ROM will help though I will try the CM10 nightlies when they boot properly. I'm ready to just bring it back for a new one but I know the Wal-Mart I bought it at is out of stock.
Any help would be very much appreciated, thank you.

Im having the same issue mine is in random places, usually top left corner but when im texting it starts typing random letters, I've been looking
for a solution or someone with the same issue you are the first and only that i have found. I am also having the dead spot issues, they tend to alternate.

Nexus 7 phantom taps
I'm having similar problems with my Nexus 7 bought in November. Worked fine for a while, now I'm getting phantom taps making typing a real pain and page scrolling can be frustrating when it suddenly scrolls to the top of the page! Anyone know if this is a warranty fix?

I had this happen one time. It freaked me out.

OP and others - have you look at the video here - post #1254 - look familiar to you at all - http://forum.xda-developers.com/showthread.php?t=1770919&page=126
A # of us had been freaked out, wondering if our secured WPA2 network has been breached and remotely controlled ...
If your device is brand new, return it & get it exchanged, or get it fixed under warranty - it's hardware related. The 16GB WiFi only model that I got from local Staples store had that problem that got worst - the replacement & upgraded 32GB unit has been flawless thus far - running stock but rooted 4.1.2 rom. I was within the 14 days/holiday time frame for exchange/return w/o stocking fees, luckily & did not have to wait for it to be repaired under warranty.
Upgrading to 4.2 firmware and/or custom Rom & kernel do not help, YMMV - of course ...
BTW, local Staples tech support counter manager said up to 20% of the N7 are getting returned/exchanged for various issues. Wow !!

After 4.2.2 my nexus7 makes phanton clicks too
Similar with this video www.youtube.com/watch?v=Tkh3W_ITwEw
I turn off screen and turn on and stop... The times in times i get it
Have solution?

I had to take my screen protector off after the update it was pressing places on the screen didn't happen until 4.2.2 update

[Q] Anyone else have touchscreen problems

My phone last week wasn't receiving texts so I restarted it and when it came back on the touchscreen no longer worked. The little white light would go on when I touched it so it knew where my finger was but any movement would not unlock the phone so I couldn't actually do anything with it. Sure enough a factory reset fixed the problem but I am still waiting for them to get me a new one in case the problem happens again to me. Anyone else have this happen to them or just a freak occurrence for me?

My son has gotten a hold of my s4 twice now since I have owned it. Both times I couldn't get the phone unlocked even though the touch screen was recognizing my touch. Restarting fixed it both times for me. Not sure if this is the same problem you are talking about, just thought I would share.

Happened to me a few times. Both screen swipes and the capacitive button presses werent registering. Happened on lock screen, call logs (swiping to call wasnt working), and swipe to answer. Pressing the home button and going back to the app fixed it. Very random but annoying nonetheless especially when not able to answer a call

Seems like buggy software to me. I've had a different issue, my phone says I have data, but I don't, I've had to restart the phone to properly pick up a data signal. This has happened twice now. Seems to be like Samsung's touchwhiz is quite buggy...

Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.

What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.

This happened to me last night, about had a major freak out.
First I have a couple questions for all of you who had this issue, so maybe we can pinpoint the actual cause:
1. Did you get any type of moisture (even just a little condensation) anywhere on or around the phone? Mine started acting up after I accidentally put my phone on the coffee table where some condensation had formed from a drink being there previously.
2. Any of you drop your phone at all? Even just a minor drop...as the day before I had a little drop (maybe from a foot off the ground), but I do have a case.
The reason I ask is because I started having this issue immediately after the phone was put on the condensation. Don't know if that was the cause, though, because I'm not sure exactly which of the steps below actually fixed it.
First I had to identify the exact problem...which I found by turning on "show touches" in Developer Options within the settings menu. This brings up a little white dot on the screen any time it registers a touch. Sure enough, I was getting "ghost touches" on the top left corner of my screen every 30 seconds or so - and it would generally last for 10-30 seconds or until I turned my screen on and off (that would fix it temporarily). The ghost touch was causing my drop down menu to pull down slightly every once in awhile, as well as not registering any of my other touches (including capacitive buttons). I knew the screen itself wasn't broken, because any addition touches were registering via the white dot - they just weren't interacting with the UI.
After doing some research online, apparently there are a couple main reasons that this ghost touching could occur:.
1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

I should not have had any condensation at all on my screen when it began. I was using the phone playing with WatchOn and setting it up for my TV, I was messing with it for quite a while and realized after a period I hadn't received texts in a long time (I normally get at least 1 every 10 minutes, I was going on a hour and a half with 0) which I thought was weird so I restarted the phone.
When the phone came back online I did not notice the white dot pressing itself anywhere, but anytime I touched the screen it would immediately know where my finger was and follow it around, but not actually press anything. When I held the power button and the little Shutdown and Restart options came up, if I sat there and just pressed either one of them constantly they would eventually recognize that I pressed something and do that action.
I was also able to get into the homescreen by getting the talk option to come up and backing out of it (The buttons on the bottom of the screen all worked fine) but once in the homescreen I couldn't actually press any buttons regularly so gave up on it.
The guy at the ATT store said he hadn't seen any other complaints about it so I did a factory reset while there (I had already backed up everything with Kies) and when it came back on there seemed to be no problems.
Like I said though I am waiting for a new one anyway, they are backordered at my local store (Should have got a new batch in Friday, not sure where my phone is now) so hopefully the new one I get doesn't have this problem nor the lag problem a lot of people have been getting.

Just the stock Phone app. My problem seemed like a software problem more than anything else.
But if you have to restart the phone in order for the digitizer to respond, thats a different story. A swap should fix your issue, since it seems so uncommon.

[Q] Bottom half of screen not responding to touch

I had an exam and removed the battery for my phone for the duration. When I put it back in, the bottom half of my screen stopped responding to touch. The screen itself is unharmed and uncracked. The S Pen still works flawlessly. However, the bottom half of the screen ("above" about 890 pixels on the Y axis) simply does not respond to normal touch. In addition, the volume buttons no longer change my notification volume. They still work for music volume, just not touch volume. When I long-press the power button, the power menu sits at the very top of the screen and has black covering the whole bottom of the screen for some reason. When I receive calls, the buttons are right at the top. Because of this, this seems to be some sort of software issue, but I have no idea what would cause it. Has anyone with more experience with Samsung devices seen this before? Multiple restarts and battery pulls have done nothing.
EDIT: In case anyone else encounters this, it had something to do with my case. I think my phone thought it was a smart cover for some reason. I enabled and disabled smart cover and then removed and replaced the case. It's working fine now.
EDIT: Never mind, that was a coincidence. The issue is DEFINITELY that the phone thinks it has a smart cover on it, but it has nothing to do with my own case.

I've had much the same problem. While the S-Pen was able to make selections that the touchscreen wouldn't, other S-Pen functions such as Air Command and being able to start an Action Memo wouldn't work. Waiting for an extended period of time (like 24 hours) and all of a sudden it started working again. However, while I was waiting, rebooting - even performing a factory reset - didn't' fix it! I just now rebooted it and it's not working again, and it's not in a case.
Where do you find the option to enable and disable Smart Cover? On the Note 2, it was (apparently) under Security / Device Administrators, but I don't find it there. The only option I could find was in Accessories / S View Cover / Automatic Unlock but changing this setting (including rebooting between settings) hasn't solved it.

Sadly, it was just coincidence that it randomly stopped happening when I enabled and disabled the auto-unlock feature with Smart Cover. My phone started doing it again and I've been unable to repair it. I went to Verizon and they wiped my phone before telling me I'll just have to get it replaced with a refurbished one. Very frustrated. Shame there aren't any AOSP based ROMs yet (like CyanogenMod)-- they'd probably fix it since the cover thing wouldn't be a feature.

Bump.
Anyone know of the APK which would handle S View Cover behavior? If we were to disable that I imagine the problem would go away. I'm still not totally sure of the origin of the issue, but it seems to come from a combination of hardware and software problems. The hardware sensor thinks I have the case on, so the software changes things around. When I call people, I get the S View Cover style call screen. If I change the toggle in accessory settings to automatically unlock the phone when opening the cover, hitting the lock button automatically unlocks the phone as though I had no lockscreen. However, when this is disabled, the lock screen is NOT in the S View Cover form-- it looks stock. This confuses me.
Any ideas from anyone else getting the issue?

Same experience
Just to add my experience as I go. This afternoon I received an error that my SMS data could not be downloaded. Upon sliding down the notifications I was unable to control much. I ripped the majority of my hair out over this.... My pen works flawlessly everywhere though. I eventually discovered it works fine on the bottom half as you described. I have to run to some appointments, but I'll touch back after I try a few things.

Maybe it was caused by the battery insertion or backplate replacement. Perhaps too much pressure or an uneven pressure damaged the circuitry, which is now loose and causing the intermittent error.
Or perhaps it was a static discharge from the battery.
Both cases seem to me to be warrenty items.

I thought the only thing necessary to unroot is to flash the stock ROM. The download is linked from the de la Vega post.

I have the same issue. I ve been trying to understand why this happened but no luck. I tried everything from updating to reseting. I first noticed it when i took the battery out as well. but the problem kinda fixed it self so i thought the phone has a spaz or something. but when i removed the battery again it happened again.
I took it to the people i bought it from and all they can say is cause there were a couple of scratches on the side of the case that it may not fall under warranty...
i was pretty angry cause its only two months old and the warranty is for a year. and the problem started happening while i was overseas so its been like that for almost a month. hopefully the sales guy is just talk cause its not up to him its just his "opinion" as he put it.
Did they explain to you why this happened? or if this is a common issue?
Hope your new phone is ok

I have this problem intermittently also. Exactly as described above.

any updates on this? im having the same problem now with my tmobile version. it fell facedown and the extended battery i had it in fell out. im going to try putting an aosp rom on it when i get home from work.

Timely post! I gave up. Verizon sending me a warranty replacement to arrive today.

I have the solution!
Please. Let me know it worked for you, so people that doesn´t like to post and only read can solve this problem.
The Problem:
The half bottom screen is not working. Including the back button, the option button and the home buttom. they only work if you use the S Pen. Except for the home button. The volumes button do not work either. So the Solution is this..
take off the battery while the phone is on. YES, do not turn off the telephone and the take off the battery. Just take off the battery while the phone is on. It should work. I hope this is the solution.
One more thing. Do not allow your phone to dried up the battery completly so this wont happen again. It is better to turn it off before it dries up.!
Please let me know if it worked for you! I will let you know if this problems start again and if was only an coincidence.Hopes it not!
This tough me a good lesson! never buy a Phone from not trusted retailer, it is better to pay the full price a good store. The people that sold me the phone has a crappy warrraty like if the screen it cellphone is complete off they wont allow me to use the warranty and my phone had faulty battery conecction so it was off. then I paid 100 dollars to be repaired then this problem.
Ok, guys please let us know if it worked so people start saving their phone

Just happened to mine as well
Hard reset didn't work, on the phone with support trying to request a replacement now.

Finally Solved!
Hi
I had same problem
I did everything u said like:
mega wipe and changing rom
custom roms
taking out battery when it's on ( I Did this but I don't know It had any effects on my phone or not!)
taking out external card
But I still Had the Problem
Solution:
But I had a flip cover and I separated that from phone and thanks God,surprisingly It's Fixed and it works like a charm!!! after that I used my original cover and there is no problem till now.
Good Luck

I haven't gone back to refresh my memory but it seems to me that all these occurrances were caused by removing the back cover. Try removing it and the battery and firmly press on every spot with your thumb. First place the device face down on table padded with a single layer of a blanket. Remove the SIM and SD card and firmly reinsert. Press the back cover on and try it, then return it for warranty if it is still bad.

I also was faced with this issue today at the start of my morning BUT I FOUND A SOLUTION
I have a Sprint Galaxy Note 3 N900P Stock ROM/ no root, no mods/custom kernels/boots etc...
My device side effects were
The bottom half of my screen was not responding to my fingers,
When you press the Power Button, The options appeared on the top section of the screen instead of being the center
When I press the volume up/down keys, The volume would raise and lower, But the screen that pops up and shows you the volume had increased or decreased didnt show up
Only way to use device was with S Pen
Basically all the issues everyone listed, I had them.
Now my solution; if the issue is a hardware issue.
After dissembling my phone to see what each hardware part of the phone controls, I've come to the conclusion that there was an issue with my USB Dock Connector section of the phone. I uploaded a image pointing which connector controls it. I tried to just wipe and clean it up a bit because mines had some residue on the underneath of it. Then I plugged it back in and it started back to work %100. After I tried restarting it a few times and shaking the device up, it still works; Although I am still going to order a replacement USB Charging Port with flex cable just in case.

fixed.
This is the definitely the hardware problem.
most likely happen if u ever dropped ur phone to the ground ----------- and reboot ur phone some what later time. (can be days or months).
Temp Solution to this problem is...
face down your phone to the flat floor or a table, gently hit the back, strong enough to shock the devide, but not that strong to crack your screen.
one other simple way is to drop your phone to the floor, screen is facing down, from about 30 cm high from the floor.
"simply, hit your device like you used to fix your ur old TV. "
that is just a temp. GL.

Galaxy S7 Edge strange behavior, Random touch input

Hello folks,
I've googled a lot but maybe I used the wrong terms or it's a rare problem. But my phone has a small annoying bug. The bug I'm facing was always there but after the latest update it occurs much more.
Most of the time it happens when you unlock the phone and start typing. In the video below you can see the problem.
Sometimes the recent apps and back button refuse to work while this happens. Not always.
Is there anyone else that suffers from this strange behabior?
I allready tried to remove the TPU case but that didn't solved the problem.

the solution is simple,just make sure ur fingers aren't wet!

Over a period of time (if you looked at your phone at an angle with the light reflecting off) the Gorilla Glass the phone needs to be wiped down, preferably with a micro-cloth (the same type you use on glasses). The oils on your hand, combined with sweat/water, can do freaky things with the touchscreen.
I have been using a stylus most of the time to type and interact with my S7E phone. Not only that I like it better I find it with my big fingers I am more accurate when I am typing and interacting with the phone.
But do not forget this S7E is completely covered with Gorilla Glass and needs to be cleaned like all other types of glass does...good luck.
Cheers!

The exact same thing is happening in my case (atleast has become more pronounced since the latest update), the recent apps & back button become unresponsive after you unlock the phone and there are random ghost touches. The problem seems to normalise after you lock & unlock the phone using the power button. Any insight on the same would be helpful.

I cleaned the phone multiple times. Actually I clean it every day.
As arun.subrm says. It goes away when you lock and unlock the phone.
Very strange. Actually it gets worse after every update. Today it happened over 3 times in 4 hours. Rediculous and very annoying. It makes it an unreliable product this way. You don't know when it will happen.
Still waiting for that moment when I accidentally buy a living room couch on ebay or something xD.
