For me maybe this will be my last Sony phone to be honest.Terrible support,ridiculous bugs.Bought it at launch date,my first unit died on sudden death,waited 1 month for replacement.After that surprise,poor Wi-Fi reception,average camera,slow updates,and again bugs,bugs,bugs.Thank god for the AOSP roms.Even Samsung keeps updating s3/note2 which are older,faster than our device,and I can bet that after Sony drops the support for ours,Samsung will keep providing for theirs.Don't get me wrong,Samsung roms are beyond terrible with that touchwiz,but generally speaking their support is much better.On the other hand I feel tempted to buy HTC M7/M8 right now,because the stock units can be converted to their GPE editions which enables you to receive direct GPE OTA updates plus I can bet the duration of the support will be atleast 1-2 more years.Not quite the same with Z Ultra on which you need ported GPE rom instead.Nexus 4 even got the 4.4.3 update,it is older phone than ours aswell,why can't Sony continue to do updates?Exept the build quality,the rest is just meh.
