Nokia N8 1 mobile phone (Xinji) can't open SMS to view the content.

My N8 1 also had this problem. My solution is grid machine, which is the most useful way to deal with small problems in N series smartphones. In standby mode (i.e. main interface), enter *#7370# and then enter the password 12345 to format the phone. Before formatting, you should back up useful things, for example, the phone book should be copied to the Sim card, and you don't need to move it after the grid. Don't be afraid when you hear the format, it has become a necessary step in S60, so … execute it!
