In principle, the device is not bad.
The display brightness can be revving up very far, so you can see even in daylight outdoors what. After switching on and a short operating time, the speed is also acceptable. There are no significant delays (in this phase) detected.
Since this is a "naked" Android, it is completely free, fixed by some "garbage". Thus one has a base, which you can assemble his desired environment.
It feels (thanks to the metal plate on the back) even quite wertig on. On my device workmanship, as with the other recessions are mentioned to recognize. The volume rocker and the on / off button function without noticeable play / "wobbling".
But now the "dark" side, where have brought me to the devaluation on 3 points ...
The display is as I said very bright, but they are very clearly to be recognized (in darker screens) halos - "light bleed" - to recognize. Had I not so clearly perceived on any device.
Furthermore, the system is somehow slower after a few hours of use. You can tell it to significantly delayed switching pages and surf the slower with the Web browser. There is then a little thick - but still operable. After restarting, it is really going again.
For me, the "baddest" Brocken but the fact is that one has with various file managers (also explicitly Android 5 support), no write access to the SD card. You can not read data (PDF or so) go there to move, as long as one does not describe directly the card in the PC. Time out quickly solve just from an e-mail a document and move on the map, is not.
Have had in this regard schoh contact with the support from Trekstor. Since the problem was confirmed as comprehensible bug and promised me by e-mail that he should be fixed with the next update.
Today on 06/01/2015 is an update to Android 5 released - was about 22 MB in size. Unfortunately, the error is still present.
With a storage capacity of 8 GB (which the Android still something branches), the write access to the SD card, a mandatory requirement.
That this tablet is obviously has no protective coating not as nice. You have to really just "look" and you are on it fingerprints. Here is frequent brushing announced.
My Conclusion:
The hardware basis is acceptable at the sale price. The atriums I can still live, because you usually light backgrounds (websites).
But are the Android 5 listed a few violent fault. Especially the lack of write access to the SD card is really bad.
Will once again to contact the support of Trekstor and then possibly return the tablet for incorrect software.
