It freezes and stops working
Conclusions: Received it the 5th of September, the second day it froze and restarted two times, today it froze and restarted itself 5 consecutive times and finally turned off. After that I couldn't turn it on, the button didn't respond. Hoping the issue is only with my device, if it is not the case, not worth it.
Moreover i'm in Spain and the plug of the charger was not an european one, i had to buy an adapter, it was not written in the specifications.
