Touch Screen Digitizer Partially, if not completely, unresponsive

Make sure you aren't screwing any screws that are to long into the back of the screen, because that can damage the screen.

I replaced the screen on my Iphone 5s and I have the same problem, my screen sometimes goes crazy.

I found a video with a similar problem.

I'm looking for solution but can not find anywhere

Does anyone know a solution to this problem?

Are you buying your screens from the same vendor? If so, it is possible the vendor has received a "lot" of bad screens.

Are you touching the ribbon cables excessively with your fingers? Maybe the connectors are getting dirty. You could try cleaning the connectors prior to reattaching them.

its possible one of the cables coming from the screen iside clipped in securely

I have the same problem of phantom touches with Iphone 5. With another (original) screen i have the same result. I've done a lot of repairs and this is the first time i encountered this. I am desperate for a solution! The repair itself was without any problem. Nothing got damaged as far as i can see.

I have the same issue along with the screen getting cloudy; there is no particular order to this it sometimes appear and then goes away. Tried a restore to factory setting without success. the issue was still present when restoring from backup.

I'm having problems with my iphone 5c. It is working fine untill the pop up boxes appear (the one that pop up when you need to enter apple id and pass, or agree to things) then it is completely unresponsive on the whole screen so i cant accept or enter anything with keyboard. It's really frustrating. I've done iphone and other phone repairs for 5 years and i've never come across this specific problem.

Seems like nobody has an answer to the solution, but does anyone know the cause? I have had my 5s for just under a year and it has never done this before. It started only today but that's long enough to recognise the issue.

My iPhone 5s is having same problem and after writing to the Apple community I came up with the solution that my Phone "Digitizer" may be having problem and needs replacement.

Furthermore, my phone was behaving normally since iOS 10, but after upgrading it to the latest version now, I'm !#^&@@ off whenever I'm trying to type text on keyboard or sometimes now even if the phone is in standby mode.

I guess now its time to change the device, as it's in my hands since 2014.
