The little things verbesserwürdigen include that something quiet voice quality when making calls, even if you have set at the highest level of volume. Bluetooth connection with my car was not possible. Have it but eventually with the help of an app (for music in the car by BT play) but brought about. The extremely thin, lightweight design, I always had the feeling that the device would slide me from your fingers ...... There is a custom-fit silicone sleeve:) ............ a true NOGO is the constant drain of laboriously compiled folder. With a launcher from PlayStore I said but also counteracted ......... The cover on the back can be removed, but the battery is "glued" So a change of the battery does not seem to be possible or advisable , Battery life is ok if you "maintain" it.
Highly recommended !!!! Super sub !!!!!
