I've found out a bug in cherry mobile R007 model. I don't know if this is applicable in some other models with dual sim feature. Follow lang sa steps to see it for yourself.
Steps to reproduce the BUG:
1.) Insert two(2) SIM Card
2.) Turn on the Phone
3.) Go to "Menu --> Call Center --> Call Settings --> SIM2 call settings --> Caller ID"
4.) Set the Caller ID to "Hide ID"
5.) Set the Caller ID again back to "Set by Network" or "Send ID"
6.) Notice the Display of the LCD.
Actual Results:
- Unwanted numbers are displayed in the upper left portion of the LCD. This unwanted numbers are blocking the intended display.
- Setting the Caller ID to "Hide ID" will eliminate the "unwanted numbers", but by doing this, making outgoing calls is impossible.
- Restarting or Resetting the phone to defaults does not fix the problem.
