I just bought the Nokia 7 plus from Amazon India website in May 2018 . The device started hanging right from the third week. The screen keeps being unresponsive to touches all the time. Locking and unlocking makes screen usable again. Please help me in trouble shooting the issue. I am frustrated.
I visited nokia service centre and they informed me that i am facing this problem because i did software update on my mobile. The only resolution to solve this problem is to restore older software version (out of the box version).
And if the problem still remains same then the handset has to be replaced.
