I was talking to my friend on call and I started using instagram parlallely due to some discussion going on with my friend. But my phone got switched off automatically, 1st I thought I might have pressed the power button and restarted it. But the same thing keeps repeating. And after updating the new software update I have started facing touch issues while playing pubg, automatically some options keep selecting. Please respond Asap I'm feeling like I got the defective product.
