1. functions like Youtube or Google Maps can not be accessed via wireless Internet and need a data account to dial.
2. keyboard does have good tactile feedback, but the keys are relatively
difficult to make, especially if you time a game does not play that
can use the upper keys. In addition, the keypad looks a bit cheap .. (irdendwo one must save)
3. The built-in speaker is pretty weak - but the sound that spits out the piece through headphones / plant (with appropriate cable) is Erstklassik!
Otherwise, I must particularly commend the system stability - although I have already done a lot of bells and whistles with the phone, läufts like ne one and has never crashed :-)
