I am using lenovo k3 note with updated version marshmelo 6.0. Sometimes it happens like random touches appearing on my screen and screen jerks many times. I have restarted my phone many a time but it happens several time in a day. I don't know what I should do. I am using this it since 1 year.
Looks like your screen and the digitizer are going bad. Maybe there is moisture inside your device. I am no expert but if this is the case try to dry it with hair dryer
Hello I have some problem with touch screen in past.
some time on low battery random touch appear and on broken screen phone have same problem.
So if problem is hardware this possibly can help.
So I make some application for hot fix this until you change new screen.
app calls Partial Screen, easy to find on google play https://play.google.com/store/apps/details?id=ich.andre.partialscreen
Hope this can be helpful.
