Parts of c5 ultra screen are unresponsive often

[bounsir]

Many areas of the phone are unresponsive many times, mainly the area where the keyboard comes up. It doesn't only happen when I use the keyboard it also happens when I'm not using it. Should I take the phone to get serviced or what?

Hi bounsir,

Welcome to the community, 

You could perform a test with the diagnostics.

Menu > Settings > About phone > Diagnostics > Device Tests > Touch Screen

Let us know the results.

I just a test for the touch screen, I cleared the picture but then came back as failed with a red symbol with an exclamation mark.

Can you boot the device in to Safemode to see if the issue continues?

Safemode

[bounsir]

I've already done that. And still get issues from time to time

If the issue is random, then it is more likely software based. This could easily be a third party application causing issues every so often. I would suggest trying a backup to the device and going through with a software repair.

However if you do not wish to perform this task, you could try removing some third party apps on the device to see if they were the culprit.

Software repair instructions

Im sure it's not a Software problem becuase its been happening randomly since I bought the device about two monts ago. Now it happens more frequently and makes me frustrated then I just put my phone down .

If you feel this is something other then software, you are welcome to send the device through to a service agent for assessment, however you would be best to speak with Customer Care within your region. Use my signature below for contact details.

One thing to take in to account here, you may resolve the issue within 20 to 30 minutes with a software repair, where as sending the device away will take longer, so a software repair is the best course of action before taking it to a service agent.

Afternoon,
I've Just bought the Phone, today, to be more precisily, and have done the updated Android.
After that I am having the same issue on my touch screen.
Type some text is too dificult, when I put my finger, the screen reconizes the another letter, Ex: If I press the CAPS key, he types the letter A.
That issue is driving me crazy, but I do not know If its only in my Phone, or its a General problem.

Before that Phone, I have had a Motorola Moto X XT1058, and never had that problem...

How I fix that problem???

PS -> I'm from Brazil, pardon my bad english...

Ah, and the problem only shows when I typing something, only in the keyboard.
