+ Long battery life + Low Price + MP3 Player - The supplied earphones are comfortable to wear hard and probably not for all ears. The bass is very weak, even if you have sensitive ears. The change for better is unreasonably expensive due to the special connector. - There is no key lock code! When the contract tariff and theft enormous follow-up costs may incur as a lock on the SIM card takes place only when naming the 15-digit IMEI and who has been in an emergency at hand? - The ID3 tags for MP3 cause from time to noise. Even the processor crashes with subsequent restart are staying me. - Even if the MP3 files are stored sorted in directories, it is nevertheless only appear a long alphabetical list, which is troublesome for several hundred MP3 files. If you want to sort by, for example, albums, then you have to take that into account already in the naming of MP3 files. - The internal camera is just ridiculous - Support is overwhelmed with detailed questions and ignored the request.
By the way: The annoying tune when you unlock the key lock can be so disabling: Profiles -> ..-> Edit> Volume> Change-> signal to minimum. If neither the manual nor knew of support.
Since I am developing software, I get the impression that was not cleanly implemented and tested in the apparatus of the MP3 player. Sad that the manufacturer such errors in their products easily accepted.
