Nice upgrade

Upgrading from Sony Xperia Z1 compact. Very good jump considering that Sony is phasing out the Z series and implementing the X series, though reviews for the X only show minor performance upgrades. Phone is slightly chunkier than my previous but still usable with one hand. Lovely screen, very crisp despite not being true HD (or 4k). So far very fast and works with all my existing apps - same slight over heating issues (expected) but no detrimental effects. Nice implement of the fingerprint reader but slightly annoyed that all the buttons have shifted down from the previous model. Still early days with the phone but so far everything as I expect from it so may update at a later date.
