I use microsoft phone lumia 535. Even on locked screen the phone will zoom on it own especially when i put it in my pocket. Unlocking the phone when this happens is always impossible hence the only way out is to use the power button and put it off. How can i solve this embarrasing problem.

Turn off screen magnifier in your ease of access settings.
