Hi,
My z3 unfortunately dropped some days ago and the back cover cracked near one corner. Plus it's slightly open. I know I can ask for a replacement, so this is not the main problem. As the back cracked, the touchscreen started to be quite unresponsive, it often shows non-physical touches, like electromagnetic interferences. Could be these two effects related? I mean, substituting the back cover could fix the touchscreen issues?
Thank you very much!
