I Dont do the upgrading phones bit i buy the top ish of the range and get/expect long ish life and i dont have loads of apps just expect basic functions to work and work well why not its a **** off expensive bit of kit . But quite frankly after 3/4 mnths the 7 edge is just poor. Screen is still over sensitive, Walk down the road short cut widgets just disapear, settings change at random, type and get 2 capital letters, type and half the time theres an annoying delay. Blue tooth in car will pair phone but not media. Blue tooth soft ware has problems with ALL devices seems to pic its own time when it'll pair and work. For a topish thats had ?? years to 'sort issues out' samsung quite frankly seem to have done next to nish i' m now running out of patience and approaching the stage where I will swallow a loss and buy something else and NEVER buy anything from them again. oh and the battery life is decreasing rapidly Moan over perhaps i'll go to sleep and wake up and my top of the range world applauded phone will be reborn into something that feels like a bit of kit thats fit for purpose.
