Galaxy Core Prime, Touchscreen go crazy - Samsung Galaxy Core Prime Questions & Answers

Hello.
So, I have Galaxy Core Prime sm-g361f, and the problem is touchscreen. When I lock and then unlock screen, touch is touching the screen itself, opening apps, scroling etc.
And when I plug in charger, then that problem go away. No more touchscreen problem even after unlocking screen. So problem is just when I am not charging the phone.
I try different rom, but problem is the same.
How to fix this?
Tnx

Hi,
It also happened to me, and I think that it's because of the device overheating. Make sure that not too much apps are running

[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

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!

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..
You found the appropriate thread, I was just now going to share the link to this thread with you as well as quoting what others experienced,

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.

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

[Q] Touch Screen Problems

I've had a problem with my galaxy s4 which made me pack it away and go back to my old galaxy s2, but I've decided I actually want to fix the issue.
The touch screen just started becoming randomly un-usable, sometimes it would work sometimes it wouldn't, It will work for maybe 5-30 minutes then the touch screen would randomly stop working and become completely unresponsive while the back,menu,lock and volume buttons would still work.
There is a bit of a crack and damage at the bottom right of the phone but it still worked a good 3 months after that happened so I don't think that could be much of a problem, and I've tried both a system cache wipe and factory wipe but the same problem still occurs.
I was wondering if anyone could help me out with this?

Replace the screen. It's a hardware problem not software.

(HELP) Tegra Note 7 Touchscreen Problem!

I bought the Tegra note 7 (XOLO India) yesterday and as soon as I switched it on I got the OTA update notification and updated it successfully to Android 5.1. From the time I booted into the new version I have been plagued by touchscreen issues, the tablet responds to touch for a while and then would stop responding but will respond to stylus and switching off the screen and switching it back on would make touch responsive for a few seconds and then again it becomes irresponsive and occasionally it doesn't respond to stylus as well, did a factory reset, rebooted it number of times and finally came across this forum.
Is this a faulty device or is there any hope for me, I bought this tablet to buy games and I can't play any of them as suddenly the touchscreen would go crazy and my character would die :crying:
As another user posted that it happens in his/her device with the flip cover, I don't have the flip cover at all.
Would rooting help, I was thinking of rooting the device and downgrading it, as there was a fix for touchscreen error posted for Android 4.4.2 but after I read that rooting voids warranty I decided to check with you guys before I did anything crazy.
Thank you in advance,
Solved?
To anyone who is facing the same problem and those who are interested, I followed the suggestions from this thread and calibrated my battery and the issue seemed to have completely gone. I put the tablet for charging once it was nearing 10% overnight and the next day unplugged it and started using it and the full ady even after heavy usage the problem never showed up, the screen is 100% touch responsive and the entire experience was 'buttery' smooth. There's one more thing that I did, I installed activitylauncher and set max performance in Nvcontrolpanel.

Screen Freezes very often

I don't know what to do with my new S7 edge. Very often screen without any reason freezes and is not responsive to any touch while hardware buttons work as they should. Is it software of hardware problem? Maybe I bought faulty unit? Please help.
If you have USB debugging on, try to turn it off and restart. I was doing the adoptable storage thing and I noticed my device got slower after turning on USB debugging, specially when using the hardware buttons to do something.
Try without sdcard.
Hi,
I change for the second s7 edge and does the same issue, does anyone have the same problem
Here it is the video
https://youtu.be/lHan4r-RHTY
OP I have the same issue with my phone and with my previous E7. The screen becomes unresponsive 5-10 times a day and I have to turn the screen off and back on to fix it.
My wife's S7E doesn't ever and it's driving me insane.

I know what the problem is, is when to much things touch at the same time on the screen, then stays crazy.
Try with the phone unlock
Ex you have a t-shirt and you want to clean the screen and you press it in to your skin, does all the time, is the same thing when we put in the pocket unlock,
But this is really a problem, my other phones don't do this.
Did you end up getting your phone replaced? I've been having this issue with increasing severity so I've been thinking of getting it replaced. This definitely seems like a hardware issue, perhaps to do with the drive the os is stored on?

Help! LG V20 extreme lag after kernel crash

Hello,
Yesterday my rooted LG v20 h990ds got a kernel crash (green screen). I pulled the battery and after that I noticed no difference.
Today I woke up and noticed that the phone was really slow. Somehow the touchscreen was not always responsive so I had to lock and unlock it again.
I couldn't figure out what it was and I thought that maybe it was caused by the root. So I did a factory reset and went back to stock (LGUP). Unfortunately the problem is still there. Does anybody know what it is? Could it be a hardware defective?
Thanks in advance!
edit:
After a few tests it seems to be the digitizer. I've installed an app to test the digitizer.
Sometimes the screen sees a short touch as a long touch. That's why it opens extra options when I try to type a letter.
I've opened up the phone to see if there was any moisture damage visible, fortunately that was not the case.
Is it still possible that this is a software problem? Or do I have to buy a new screen?
edit 2:
The phone is functioning normally again. I disconnected the screen cable and plugged it back in again. Probably it was a loose contact.
