I have owned the C5 Ultra for about a year. Over all I am disappointed with the phone for one huge reason. The touch screen on the C5 Ultra is glitchy. I have googled the issue and found MANY users wth the same problem...and no real solution. When using the phone I sometimes have to touch the screen 3 or 4 times to get it to respond. The problem seems worse on the right side of the screen. It is INSANELY frustrating. I recently updated to Marshmallow and it did not fix the issue. The work around is to enable GLOVE MODE. This fixes the issue in that you only have to touch the screen once to get it to respond...however, it ends up causing the screen to respond to ANY kind of touch...so if it is in your pocket and your screen pops on due to a text or alert, you end up "touching" the screen in your pocket a million times which causes the phone to crazy to the point of locking up. So you must decide which is the lesser of the two evils. Ridiculous...and an absolute deal breaker. My iPhone 4 (seven years old now) has a monumentally better touch screen. Shame on Sony...I expected more. I will not buy another Sony smartphone.

i have the t2 ultra i like sony products they update well. Now between the 2 phones the one problem i had with it is one gig of ram . the thing would make you delete apps cuz your ram is maxed, the c5 ultra has double i would expect this to help out alot plus it has otg support and 6.0 which allows you to save apps to the sd card. my other half still uses the t2 ultra. though ive moved on to the samsung s6 edge plus.
