UMI eMAX Touch screen issue + Ghost touch issue

Ndruu

\n\nI experienced this problem and the two solutions i found that worked for me:
1. Grab the four corners of the phone and give it a little twist (don't apply much or too much force!)   No, don't do that, it won't help.
2. Restarting the phone always helped but this is the longer solution.

Edit: Actually, in my case this ghost touch issue was getting worse over time. I tried resetting, flashing new ROM, nothing helped.
Today i removed the hardened glass screen protector, put on some cheap foil, and looks like the problem is gone -i really hope so-. knock-knock-knock

Hi everyone,  I've read through all the posts and I will look into the static issue.

My phone was perfect at first.  No trouble for months then the ghost touch started, right after I told someone on a forum that I didn't have any issues with it!

I looked on this site a while back and saw the recommendation to put on the 'show touches' option in the input section of the developer area.  This showed me that when the phone was held horizontally to type that the affected area was the space covered by the letters v,b and n.  When I am on blogs and scrolling down, the ghost touch will occur here and acts as if I had swiped the screen to go onto the next page.  Very annoying.  When I am typing horizontally only the letter b gets inserted into words, not v or n.

I tried reinstalling but this didn't work.  I tried flashing a new rom (manofwar) and the issue disappeared for about 2 weeks but then came back again.  It is intermittent as others have said.

I would rather not pay to get it sent back but it seems like the easiest option.

As I said somewhere before. It is touch screen hardware  problem.  Ghost typing mostly dissapear if you press  the screen firmly down as you want to clean it. I am planning to put the phone under some heavy books for a while. This problem with a phone is so annoying that sometimes I do not care if I break the phone. Shit.

You can try to do this: go to SETTINGS-developer options-SELECT RUNTIME and switch from DALVIK to ART.  
For now I didn't noticed eny ghost touch problem.

That must be an accidental coincidence. Changing the runtime from dalvik to ART can slightly increase the performance, but has nothing to do the with the touch screen.

Guys. I've done a little research on this and. It's usually not a software problem. Sometimes the makers of the phones (usually with the cheap Chinese ones like these) they forget/don't use proper techniques for insulating the screen digitizer. Which means you will end up getting a short. Causing the ghost touches. (When the phone gets cold it gets worse) If you take the phone apart and insulate the screen digitizer with electrical tape or something it should fix it.

Searching terminated. Install "Fix Me" apk, and calibrate the screen. Fixed.
