It was a powerfull phone I guess but when I use it the processor and all was ok.
But I didnot like the camera comeon its 21mp still lg g3 13mp camera gives much more better quality than the xperia z1 compact and the front too isnt good enough and the the phone is too fragile as soon as it drop from my hand its back and front which was made of glass I guess broke.And for the replacement the service centre ask alot of cash which you could even buy a brand new phone.
