The touchscreen issue is resolved at last since the latest firmware (17.1.1.A.0.402, WiFi).

Looking for a tablet I was successful. Important:

- Light and thin
- Battery life
- Speed
- At least 3GB of RAM.
- At least 32GB Internal Memory..
- From 10 inches and full HD resolution
- Maximum total memory: ext. microSD card up to 128GB! - Is appointed - (int. + Ext = 153GB.)
- Recent hardware
- Ext. Keyboard for example. emails, Office, etc.
- No Knox and as little as possible Bloatware
- Integrated Backup System
-

After my intensive research and my wishes, I quickly realized that this would not be so easy I first tested several Samsung tablets and then came to the Xperia Z2 (WiFi).
I use the tablet for 3 weeks now and have to say that all of my conditions have been met.
It seems to me at a review of it to learn information before buying, which is unrivaled, or are unclear.
Ask if you are missing important information, I try to respond promptly.

The low weight and the broad framework, we can grow the tablet without problems for some time in hand. With a thin frame to get accidentally while keeping on the screen, replacing unwanted inputs from.

For speed, I can only refer to several benchmarks that I've uploaded here as images. These speak for themselves.

It always amazes me how quickly loaded a larger app, install and open
Here you can tell in reality been the superiority of the tablets. Who does not believe this, I can not help, you have to have even seen once.

Micro stuttering in vain (homescreens, Videos, Apps).

Other Tablets me a greater heat generation is playing, benchmark and negative attention the Flash Player. Last but not least, even the battery is charging. Were questionable hot these devices, if you did both. Where then is because the mind when I play when logically the tablet has to load it, but just that promotes heat generation in addition.
As an electronics I know suffer the microchips and especially the battery including the warmer these components are in the long run the. I just remind you that you must expose these devices to any heat source, such as. Car in summer.
Therefore, I count on the development of heat, especially with such a thin tablet and the fact that the battery is installed firmly.
The Xperia Z2 Tablet you have already quite demanding before it is even slightly warm at one point.
This shows me thus a perfect thermal management and how much Leistungsresserven this still has.

It's strange, in a car or drill one would be at a constant overheating fingers ...

From the free internal memory (25,54GB) are still 25,11GB available.
On the external storage. SD card you can via the Settings / Memory / Miscellaneous
only photos, videos and music automatically outsource.

Since Android Apps KitKat no one can unfortunately more on the ext. SD card outsource. I hope that either Google or Sony finally responds even here. For this, only an additional entry (see my pictures) required. Sony lets go

Bloatware: One must distinguish between 3 categories:

Google:
Must by the manufacturer of the overall package of Google be taken. This can, however, disable predominantly in the settings.

Manufacturer:
Sony has predominantly software on the Z2 which you also can uninstall it. The small remainder can be deactivated predominantly in the settings.

Third party:
Can all be uninstalled or disabled.

Thus, the tablet can be configured according to your wishes.

Native backup system:
System and Application Apps with data (incl. Scores) and settings, and media files on the external storage. SD card and / or USB flash drive are stored.
In addition, all settings of Android settings can be saved.
After a system reset and restore it now has all of the programs, Scores and settings back and the original from of system. What more do you want

The tablet has a great and very loud sound ... If some of you are wondering now irritated:
How does it work?
Quite simply in Settings / Sounds / sound effects: successful click selection.
Clear Audio + and dynamic normalization

And already the soft and delicate tablet turns into a great sound Monster ...
Must we have heard for ourselves again, otherwise you do not believe it.
This is with the loudest groooßem distance tablet without equal to oversteer.
As you just heard ... Well done Sony Sony out ... :)

Optional Hardware:
ext. Bluetooth keyboard works perfectly for example. emails, Office surf,

Installation in 2 steps:

1. Bluetooth link:
Bluetooth in Tablet on (Settings / Bluetooth).
Press and hold for about 2 sec. On the Tatstaturrückseite the Connect button, flashing up on the keyboard top right blue LED anfängt.Jetzt you go to

Tip:
Between the running apps can be either with the Alt key (hold) + min. 2xTab button or
Win button (hold) + min. 2xTab button switch.

The program Sony own:, SmartConnect 'you can define automatic processes, such as .:
If the keyboard is turned on, WLAN switch, open my email and / or browser, Office ...
Equally you can for example. set off after that ends the browser and the wireless is turned off.

This program recognizes the way also a USB flash drive. eg. Auto. sync, backup, file manager, etc.

A Bluetooth mouse can also be connected:
I use a Logitech V470 Laser Mouse. Simply step 1
Settings / Bluetooth / Search for devices (top right)
repeat this but then without numeric input).
This works perfectly for's Office and Web sites, etc.

In addition, I bought here on Amazon me a folding stand, magnetic USB charging cable and a data cable OTG for the USB flash drive.

Update:
I have now ordered a SanDisk Ultra 128GB microSDXC Class 10 memory card (UHS-I, 30MB / s, SD adapter, Android Edition) at Amazon and these are my experiences:
- Configuration:
Load and you will be recognized ... 121GB are available.
- Benchmark values ​​with A1 SD Bench (A1: dev team):
Read 42MB / s and Write 15MB / s

- Note: my old 64GB SanDisk Extreme Plus microSDXC Class 10 memory card (UHS-I, 80MB / Sec) + adapter Mobile came to success values.
- Benchmark values ​​with A1 SD Bench (A1: dev team):
Read 42MB / s and Write 38MB / s

One must decide between write performance and memory size now.
Well, but are 121GB 121GB ;-)

I could write much more about the Z2 because it is simply a pleasure to work with every day, read, play ... Have now the review with the keyboard and mouse about 2hours written and he still has 89% ...: )

A request to Amazon:
