I've had mine for almost 6 months and it shows no signs of quitting. Actually, the longer I have it, the more efficient it runs. It learns how you use it (a little green light flashes) As it learns, it flashes less & less. Now it flashes only when I install a new app or try something I haven't done before. I've also dropped it a number of times without harm. I do have a case & a bonded screen protector. This is the most expensive phone I've had and I'm very happy with it. Good luck .
