[Q] [DISCUSS] Screen usability while charging

When my phone is plugged into the charger, the screen becomes almost unusable. Very hard to scroll around, different letters get selected while trying to type. If i hold my finger still on the home screen, it jumps around like its having a seizure and wont stay still. Unplug the charger though, and everything works perfectly.
Was just wondering if anybody else finds it difficult to use the screen while charging, or if anyone notices any difference in screen sensitivity while charging?

I don't have your problem.

Neither have I encountered this problem
Seems like you have a faulty device. I suggest to go to a SE center and ask their opinion and maybe ask for another one

I just found an old charger and tried that, and no problems at all, so the issue is something to do with the charger im guessing. Weird....

my phone is connect to the PC and I am not having any problems, did you try charging it through a PC?

i encountered the same issue when charging with a nokia n900 charger.
while with PC charging it seems ok.

Not had that problem with whatever charger I use. I have used the in car, desktop and PC connections, also used an HTC and ZTE charger with no issues.

Have not experienced this problem.

I had this problem and managed to fix it.
Mine had nothing to do with the charger though. Typing went crazy whenever i hit the space button or the p button. Pressing p would produce a 2-3 y's and pressing space would produce a , and 2 spaces.
I cant remember EXACTLY which fixed it but i can tell you what i did -
1) Installed a cache cleaner. Cachemate. (although i have recently switched to Android Assistant). Performed a power cache cleanse with Cache Mate.
2) Went to Titanium Backup and selected "Default Input" and "wiped Data".
However, here is the thing i THINK fixed the problem -
1) Went to market place and installed gingerbread keyboard and selected it as my default input.
Switching which keyboard you use i believe resets the touchpoint settings. I prefer Gingerbread Keyboard btw, use it as my default now.
Be careful when you wipe cache or data using titanium backup. I accept no responsibility for any misuse that causes your phone to function incorrectly

A lot of Android phones do this with incompatible chargers.

Happens to me when I keep my phone on a flat surface it goes all mumbo jumbo and I can't even unlock the screen properly

"Jerky" / not accurate screen (video inside)

Anyone has this problem? When I put my finger on the touchscreen, screen moves up and down like crazy. It gets worse when I move my finger to the side of the screen.
I tried different roms, different kernels, nothing fix this.
Only when using the touchsentivity app and changing the value to any value and clicking apply makes this behaviour disappear for a moment.... after locking the phone and awake it, same thing happens again.
It drives me crazy because I always put my finger on the screen when reading something.. or in some apps or games when I need my finger stay on the screen it gets annoying. .

This isn't normal. If you can't solve this problem with a factory reset, get your phone exchanged or repaired.

That's what my HD2 used to do. Couldn't type anything on it to save my life. Think I'm gonna have to check my SG2 now I've seen your vid.

Thats probably because the custom kernel your using has a different value for it and the app is setting up 5, try it with a stock kernel and perform a factory reset and see if the issue still occurs w/o changing the TSP value.

I got the same problem. I do that sometimes too.. scrolling up and read while holding my finger down, it just jitters or something.
You're not the only one, but not sure how widespread this problem is or if it is normal or not..

Mine is also jerking when holding the finger out at the edge lol, looks retarded

Interesting...so if I disable the touchscreen fix the problem goes away. If I reinstall it, no matter what the settings are, I get the jittering effect at the very corner of the screen.

Yep I got same problem, when reading and holding down on the screen it does the same.
On Litening Rom 1.5 cant remember if it happened on stock rom though

I get this too, my SGS did it as well.

I tried this multiple times on the edge and it does not jitter at least on the phone that I have.

Mine did this when it was plugged into the mains (using a non-samsung) charger. Does not do it when plugged in via USB or on battery.
Is yours plugged in?

So some have it, some not?
I always had this thing, since KE1.. now on KG5. Stock kernel, custom kernel, rooted or not rooted doesn't matter.
Also, it has nothing to do with the touchsentivity app. The app even fixes it temporary when applying a new value, but it re-appears when locking-awaking the phone. (I tried to enable the service option on the app, so it will apply the value everytime I awake the phone, but this does not work)
I just tried it when plugged in in the changer, it seems to do the opposite... when plugged in I don't have this effect anymore. Once plugged out it starts again.
I also have SGS1.. this does not happen.

So how has this worked out for you? I have this too but just a little bit less. It also stops for me when plugged in. I wen't back to the store with it but saw that the shop model had the problem too so I decided to not return it. How about you?

I checked and it appers that i have i too. Didnt notice it till now.
It is occuring only on the left side when holding my finger.

I did not notice it too...and yes, mine is "Jerky" too...

Mine is fine, so looks faulty to me.

weird left side
I have to say this happens to me too but only when at the VERY edge of the screen,on the left.
There is something very weird about the left side of the phone.
1. the touch issue
2. the yellow tint
3. the glass is more raised than the right side(check it out) its like there is less bezel showing on the lower left part of the phone than the right side. I've checked 3 s2s and they all had it.

I have this all over the screen but not as bad as on the left side. Could someone install note everything and make a paint note with the smallest brush. Then try to make some straight lines (without the phone being connected to the a/c). Draw them really slowly from the left to the right. Mine usually jumps 1 pixel up and/or down and is a bit wavy (which isn't normal for touchscreen phones cause I tried the same thing on my friend's optimus 2x and the lines where as straight as could be). Maybe if you guys make a screenshot (home button+lock button) we could compare them and see if there is really a problem with specific phones or with the Galaxy line in general.

This was something I noticed when I first got the phone, if I kept my finger on while browsing, it would "shake" and be extremely annoying. Same thing happens when you hold an application in the left corner of the screen.
If my phone is charging, the problem is gone! It's smooth, and doesn't "shake".
Soon as the charger is removed problem is back
Going to return this tomorrow and see if they'll exchange it.

Just another 'my phone is red, yellow screen thread'. Does it affect your day to day usage? If it does,i too is concerned.if not, then what's the point in looking for non measure issues? This issue was up like 4 months ago and now, back. Y'all just return your phones and close annoying threads.

Touchscreen problem.

I bought my TF300 at Amazon June and basically it works well until yesterday.
The sympton is like someone keep tapping the specific areas of touchscreen and never stop, actually i haven't put my finger on ,even i didn't hold the tablet, just put it on desktop.
I had to tried to hold the power button to restart the TF300 several times and finally it looks become normal.
But this morning, when i power it on, the problem occurred.
Anyone have idea this problem ?

Weird. Do you have a screen protector on? If you do, you might need to take it off. If you don't, try cleaning your screen with the cloth it came with, also do a cold reboot (this is done by turning off your tablet then turning it back on holding the volume down button until you see some text in the upper left of the screen, after that just leave the tablet do he's thing, meaning don't touch anything else until it boots up). If that doesn't fix the problem, you will need to try to do a factory reset. If that fails to fix the problem I suggest you contact ASUS support or if its still under amazon's warranty exchange for a new one.

Mine wasn't picking when I pressed on the screen... I open the back and saw a ribbon cable was kinda loose and held with tape. So I pressed it in and put more tape on it and now its fine with the response from the screen.

stock rom , US .30 ,i think.
It rooted.
since the day i posted the problem here,i used out the battery and recharged it to full,the issue didnt happen again.

Fix for touchscreen issues
Hey guys,
I thought I'd post my solution to the same problem. It is a hardware issue and I figured it was because of how thin the device is. Basically, I noticed it when I would be playing or if the device started to heat up. Since the battery and screen are so close together, I figured there wasn't enough space and that the heat from the battery was making the tablet think that there was a touch input when there was none.
My solution was to open up the tablet and take the battery out. Then I put slivers of foam (about 1/2" x 2") in between the battery and the screen. Since then I haven't had problems with the touchscreen.
I hope this helps you guys with this problem.

[Q] Touchscreen problem: hardware or software?

Hey
I had my Nexus 4 for a while now and today suddenly I have a problem with my touchscreen. It suddenly happend, it didn't fall or nothing.
So, the problem: there is a part of the screen that doesn't function properly. It's at a certain y value or height. It noticed this today when I wanted to swipe down the notification bar. Half the time it flips back up or doesn't do anything at all, sometimes it does work. If I swipe "fast" before that height, it usually works.
I downloaded an app to test the touchscreen and at that height it registers 2 or more fingers or it snaps above or under that line.
Can I fix this or do I need to bring it back for warranty? Is this a software or hardware issue? I also did a reset, but that didn't help...
I uploaded some videos to illustrate (can't post links so insert this in the youtube links please):
1. The problem: /watch?v=kNLbSU0smcw
2. Test: /watch?v=B8ERuBtYeBA
Edit: When I hold the phone horizontally, the notification bar works perfectly.
Many thanks,
Aaron

Update: from yesterday until now the screen was even worse, like I was touching it with 100 fingers, it went totally crazy...
A few hours later it works perfectly normal again
Any ideas?

Ok, I still have this problem...
However, the problem is present and I switch a few time to the lockscreen and back, it's fixed most the time. So I think this must be a software issue.
Maybe undoing a few updates might help? What's the best way to do that?

Are you on a Custom ROM / Kernel? If so, go back to stock ROM and Kernel and see if the problem still exists.

No, never used other roms, kernels or rooted..

I have the exact same issue.. Did you manage to solve it?

Nope, but sometimes I can use it like a week with no problem and sometimes I have it everyday.
At first I thought it might be because of the low temperature in my bedroom, but I tested it and I don't think that's the reason. I removed the cover I bought too, but I need to use it a bit longer to be sure it doesn't happen without cover. After that I'll put on the cover again and check again.

Is it possible that it happens when it is charging? Mine does this when it is charging.

No, as far as I know it's not affected by charging. The first time I had this problem I just picked it up from my desk..

I had touch screen issues as well, less than one month after getting the phone.
Occasionally, after pressing the power button to power up the display, the touch screen would not be responsive. I need to turn off/turn on the display again for it to work. It finally conked out one day when the entire part used for soft keys doesn't work anymore. Just an instant before this happened the touch screen started acting crazy for a few seconds.
Had the touch screen and LCD replaced under warranty.
The problem now is there's a bright white blob in the upper right corner of the LCD, and the proximity sensor sometimes doesn't work, resulting in no display when making or receiving a call.

Yeah, turning the display on/off a few times (so lock/unlock) helps sometimes. The warranty is a bit of a problem here, I bought it in Germany (MediaMarkt), but I live in Belgium. I tried registering at the LG site (Belgian version), but no option to select a Nexus 4 there for support... I did a live chat at the LG site, explained my problem and the helpdesk guy just left the chat I tried to contact them using Twitter, but they never replied. I asked MediaMarkt and they said I'd have to bring it in the a German MediaMarkt... It's a long way to Germany, so I'd rather not do that unless I can't solve it and they reject the warranty in Belgium (although they are obliged to).
I'm also worried that I'd get an even worse phone, like the problems you have with your new phone :s

Ok..I have a RaZr and this happened to me too. One fine day. Playing a game. In the middle of nowhere. I was scared. S*it scared. So what did i do?
I just did a soft reboot. Pressing the right combination of keys and the phone reboots.
Also, here is a very long drawn attempt, but can u try doing a wipe data/dalvik/cache?
Go into stock recovery and do the rest.
It may help, it may not help.
WARNING: YOU WILL LOSE ALL DATA while doing this.
And oh: I am sorry but I think this is a hardware issue. I may be wrong.

I had the same issue with my EVO LTE. It would go away and come back just like yours. It wasn't a software problem , so I sent it in under warranty and they're fixing it free of charge.

[Q] momentarily unresponsive touch screen

Hi guys
I have moved from iPhone to a note 4 and loving it!
I was just wondering if anyone has found the touch screen occasionally doesn't respond to their touch and you have to touch it again. On the iPhone it only ever missed a touch if my finger was in the wrong place, but it never happened on the keyboard. Every so often maybe 5/6 times a day I touch a key on the keyboard and nothing happens, when I try again it's fine. I can't reproduce it, because when I tap anywhere on the keyboard something gets pressed. I was just wondering if this was normal?
Hope you are enjoying your phones!!

Anyone?

It's most likely cause your palm is on the phone. One of the downsides of a slim bezel on a big phone. Also keep in mind if your spen is on the screen, your fingers won't work. A case might help.

I thought about another part of my hand touching the screen, however with half my hand layed across my keyboard I can still type with the other hand. Thanks for the response

I Pele tried factory resetting today and not installed any apps, but it is still happening

I rang Samsung this morning and they advised I return I to the store and get an exchange. Luckily my local store got its first batch of note 4s in this morning and they swapped it out. I restored it all firmware updates put on it and now works fine! The only thing I haven't installed is a Google play system update thing. I was wondering if that was the cause x

Similar issues
I've had similar issues (in fact, that's what brought me here in the first place). Initially, I was able to tap on the screen in the text box and then continue typing (I use Swype). However, now my messaging app (default Messages) just freezes up, forcing me to close the app, clear the memory, and relaunch the app before continuing.
Were you using the default app and/or Swype when you had issues? I'm going to try to factory reset my phone to see if it helps.
It's taken a couple of weeks for this problem to develop, so please keep us posted if this problem arises again on your new phone!
Edit: Also want to point out that when I text, I use one hand to hold the phone and only a finger to swipe my text. As such, only the one finger touches the screen.

unable to use touch screen. only hard key were working >>Note4
Hi everyone,
today i just had the same problem with the touch screen. no response at all .. after i tried and took out the spen .. and surprise it worked with the pen.

Same thing happened to me last night. The touchscreen became unresponsive while using chrome. The phone was a little warm but not bad. I didn't try the pen, sounds like a good idea. I am not certain it was a touch screen issue with mine. Almost more of a processor issue. I got the phone to lock. After pressing the menu or lock button to wake the screen it would take 5-10 seconds to wake. Then I could swipe my unlock pattern. It would not show any lines. I would wait, the screen would turn black after timing out in about 5s. The about 5s after I could hear the speaker make the unlock sound. I ended up doing a battery pull and that fixed the issue. Anyone else have something similar?
Should I try and replace it?

Observe to see if it happens when you're using other apps too. Chrome has been notorious for causing all sorts of problems, like reboots, freezes, etc on some devices.
Also it may be worth installing Chrome Samsung Support Library.

Got the same problem after 2 months of normal usage... I initially though I had installed a third party application which was causing the system freeze but this was not the problem.
- tried factory resetting and not installed any apps, but it is still happening
- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!
:crying:

Same thing is happening with my 2 months old note4 since two weeks ago. An horizontal line 1.5cm in width about 1/3 from the bottom of the screen, became unresponsive. At reboot it works sometimes then it becomes unresponsive again. It looks like in the image I attached, the difference is that the area is horizontal, not vertical. I'm taking my note4 to the store today for warranty, hopefully they will replace it. I haven't abused the device in any way, I have a screen protector since its first day.. I really hope this isn't a serious problem that affects many users.
Just like some of you mentioned above, the pen has no issues on any area of the screen.
Cheers!

Never purchase a device without a return / DOA policy. Not worth the hassle. If it hasn't been 30 days, you should call your credit card company or Paypal and place the amount on dispute, wait, you purchased from another market, please tell you didn't pay by cash.

same thing happen to my note4 today. the only difference is that yours was fixed for a couple of minutes after removing the battery. my note4 wasn't fixed after that. Only S-pen works, touch screen with fingers wont work. you mentioned you're note4 is getting repaired, did they tell you what may have happened to it so that i'll get an idea of the cause..

I have this problem after I flash CWM recovery, before this was flashed with twrp recovery, I reflash stock rom with odin, I flash many times CWM and TWRP and I still have the problem, my warranty it's void now but I think to go at Samsung store to see if they solve my problem. This problem look like a driver for touch corrupted, if somebody find it out how to fix or have any ideea please weritte here, thanks you

I've started to have this problem as well, lower part of the left side of the screen sometimes registers touch instead of scrolling! Very annoying, tried to update recovery, tried tapping screen, doesn't help. The worst thing is I cannot reproduce the issue at will... It seems pretty random.

Unfortunately, if the phone is on Verizon, the dialing codes will be disabled.

Potential fix.
Please excuse the necropost But I came here looking for a solution from google and others may too. I found a way to solve this issue/s.
There appear to be two issues affecting this.
1. Overloading the processor.
2. Static.
If your touch input is lagging or doesn't register at all but then suddenly does a few moments later, its likely a type 1. problem. I fixed this by disabling resource intensive features such as s voice. This also improved battery life and overall performance considerably.
If touch simply doesn't work at all, but s pen works fine then the problem is more likely type 2. That being static buildup in your person. Simply touch something that can ground you and it should fix the issue. A metal tap should work. Be wary, you might even get a little zap as you discharge
