My new Xperia T2 Ultra with Android 4.4.2 is a nightmare: I need to reboot 10 times a day, unable to multi-task, apps crashing all the time, Google apps keep on delogging me from my accounts all the time, etc. Impossible to use day-to-day due to poor performance thesis. A shame. Certainly not worth the price. Do not buy or you will regret it.
