Not bad but not great either - update ?!

1) The Custom interface is really crap and immediately flew out a) Runs slowly b) jerky very strong and lead c) apparent in many crashes> Since an update is needed!

2) build quality is not so great (back very thin and cheap plastic - hopefully hälts ...) - rest ok, nothing creaks, but you can do much better.
3) Sim cards with different sizes (still have old and new is accordingly ok ...)
4) Camera only average, enough for snapshots, but makes them "light" images

Good:

1) Display beautiful light and good color / HD 5.5 inch just about acceptable - 5.7 inches was me definitely too big and impractical in everyday life.
2) processor fast enough for games (Angry Birds Transformers jerky a little, but running)> Antutu Benchmark delivers 17708 points / that I tested 1.5 Quad Core Phone from Avus yielded larger processor only 300 points higher (approximately 18000 points)
3) Good wifi module with antenna - better reception even in difficult corners - fast download speeds!
4) Dual Sim for 2 different card + SD Slot (thank goodness no Combined Slot - otherwise the 2nd Sim is not)
5) Little preinstalled software
Holds 6) Good battery contains at least 1/1/2 days
7) exchange battery in the accessory (costs here at Amazon 50?!)
8) German company from BW
9) Accessories available (no good Flip Case - for 15 am become find it here ...)

All in all, so far satisfied - if everything continues to run well, I'm happy with the large screen and powerful battery satisfied.
