@Abhishek_TV @RohitRathi My phone is always in performance mode. I already stopped using power saver mode couple of months ago. But still I am facing this lag with the performance mode switched on. Just to be sure, I also did hard reset and cleared cache and formatted my phone of all data but nothing helps. I am now confused if is due to the recent OS update or the updates you pushed via Play store for Smartron apps and it's services. Also as I mentioned above, I am facing delay in feedback from the power button. Sometimes I have to press it two or three times to turn off/ turn on my screen or to get the power off menu. Sometimes I have to press it really hard to get the feedback. This is not the case before. The one click of power button doesn't give me the required feedback at all. I hope this is not a hardware failure since I have a brand new piece, not even a year old.
