The unit makes a solid impression, well finished. Good voice quality when making calls. The operation is simple and comfortable. Looking for something you can find on the net an English Manual, unfortunately no German; That, to me, however, no problem. Surfing the Internet and mail fold fine. With an appropriate app (Android Terminal Emulator) as a Linux system. Very good radio reception (with supplied headphones) about App Audials. Leistungsfaehiger battery holds in standby longer than a week. Camera is useful, as you should but do not expect any miracles. At the price a recommended purchase.
