Installation of Apps and set up the unit just went.
On the web there is a Syncsoftware, with which one can do much.
The front is solid - the Gorilla glass is insensitive to minor bump.
The back - even glass should be protected.
The speed is very good.
No stuttering in applications, games or videos.
Also, the RAM memory is designed very well.
All in all, everything was very well coordinated.
The battery is unfortunately only average. Here I wanted more.
Similarly, the volume of the speakers - here should be improved.
Wireless internet is available in 2.4 and 5 GHz mode possible.
Once saved a connection, the Z3 automatically connects with it when you're in range.
The reception in the telephone network is also good. The Z3 switched quickly in the different standards.
The compounds are stable and even conversations can be heard well - as the voice quality to the called party is very good.
The image - yes the picture .... that's something of sharp and brilliant - as my old S5 comes not with. Great colors and excellent contrast.
The 16GB of storage internally enough for me completely.
If that's not enough, you can insert a MicroSD. I also - but only for images and music.
Setting the Z3 to the individual needs to be set sufficiently and easily.
Sony also offers a lot of free apps that let you "play" can.
Waterproof eats well.
That was the first thing I've tested. I have the Z3 simply thrown in the filled bathtub.
When I retrieved it again, I have directly tested the touchscreen.
The works already in the dry state really very good and precise - but also after the bath everything worked.
I could make calls, listen to music and take pictures.
Oh, and photos I was able to shoot underwater!
Photos with the Z3 are excellent.
Through the many options and additional apps from Sony so you can really make all kinds.
Since a camera is no longer necessary.
Also create movies is great.
Especially videos in 4K - awesome. Something of sharp, believe it or not.
Why I write, it gets even better?
Now, since there are some Android 5, what was verschlimmbessert.
But that is not the Z3 but in the software.
The battery makes partly already after 12 hours (without being a power user) limp.
In forums you can read that it is so many.
I wish for a better battery efficiency and better speakers.
Whether that is so good with the built-in battery ... I do not know.
Nevertheless, a strong buy recommendation from me.
