Bought this phone and the screen broked twice in 3 months and got it changed from HTC service center Bangalore for Rs.7000 each. I put tempered glass and took extra care for the phone after the first breakage but all went in vain. My phone failed from my hand and I was on a bean bag atleast 30 cm from the floor still the inside screen broked and nothing happened to my tempered glass.
I think its a manufacturer difect the phone is very light in weight but most of the weight is concentrated towards the screen, which can be a major issue for easy brakage of screen.
Would suggest you not to buy.
