Does anyone know if these issues are normal or not for a Desire on o2 (branded). Cant currently send back to them as not mine but friend i bought it off who is currently away on holiday for a week. 
1) Doesn't turn off stuck as power off screen for 30 mins +
2) Often after 3 days cant access SD card and needs reboot
3) Vibrate on text writing works for a few words then stops and then kicks back in
4) Texts wont occasionally send even though full signal then when manually retry to send stuck in loop of failed retry and vibrating/beeping until rebooted
5) You tube comes up "network error" which clear then works fine
6) Randomly reboots itself when on satnav/google maps
7) Doesn't pick up wifi always unless once turned on go into setting then it finds it
Cheers for any advice!
