Hi Acidreflux360 ,
I hope it is not too late. I had the same issue. And It seems in my case, like it was due to my faulty headset which was sending weird vocal command, like starting Samsung Music app randomly, even when the phone was locked.
I hope it helps.
Hello CNET, my first post on here.
I have a Samsung Galaxy A5 (2017) that was purchased brand new from a well known high street retailer in the UK in September 2017.
I previously had an iPhone but wanted to try this as I read very good reviews of the Galaxy A5 as a well priced mid-range phone.
However I have had constant problems with the touchscreen sensitivity.
The main issue is at completely random times when typing or trying to select an app or tap a button, the touchscreen will not respond. I have to tap 2, 3 or at times 4 times for the touchscreen to respond. At other times, the touchscreen is absolutely fine.
I have contacted Samsung Support online multiple times, but they just give me generic advice such as do a soft reset, turn on the phone in safe mode etc. I have tried this multiple times but it is clear to me it is a hardware issue and not a third party app issue.
I have taken it to a couple of Samsung stores, where they tested the screen and there was no problem when they tested it. Just my luck! As when I am back home using it myself the touchscreen is randomly unrespomsive again.
Does anyone else have this issue with their Samsung Galaxy by any chance? I hope someone out there reading this is aware of a fix to this problem.
Thank you.
