P.S. Is KitKat faster than Jelly Bean on HTC One?
I've an HTC One (Unlocked) running on Jelly Bean 4.3 with Sense 5.5 but the thing annoying me is latest KitKat update is not available for my region (Pakistan) yet. Is there any way to update my device without rooting or anything else? I don't wanna take any risk!
