Nokia C2 01 Rm 721 V11 50 Update Issues
When buying my phone, a general firmware version of 10.50 is included. The phone works well even under extreme conditions. When Nokia released the new version 11.00, they announced improved performance, improved usability, and updated application. Nokia strongly recommends updating the versions published on the phone. So I try and everything works fine. But there are two things I noticed about this version of 11.00.
 Strange “temp” folders with the extension .tec and .arc are often automatically created on my memory card. They are unreadable.
 As soon as the total conversations reach more than 100, the “conversation update” remains active, especially when new messages arrive.
How can I get through these issues of nokia c2 01 rm 721 v11 50 ? Please help
