The only possible criticism: the permanently installed battery. The can probably not change so easily, if it is time at the end, but my running even after half a year in full use yet almost like on the 1st day.
As an accessory I can, the silicone shell of Mumbi (<4!) And also recommend their screen protectors as well as the magnetic charging cable of Victsing. Precisely this is highly recommended to protect the USB flap and remains watertight.
I can only say that there is still liquid, as in the young age runs after half a year and with ~ 150 installed apps, more than enough computing power (led quite a while after release nor the 3DMark leaderboard on!) And I ( can except the Z3 Compact) imagine a better phone.
