I wonder what happened to my mobile phone today. Some networks don't display signals, so short messages can't be sent out. I brushed the xp framework a few days ago, and it was fine before.

1. In order to understand and solve the abnormal problems after swiping the mobile phone, it is suggested that the mobile phone be sent to the nearest service center for testing, and the service center will determine the specific problems of the mobile phone according to the test results and further handle them.

2. Due to the risk of brushing machine, official website did not provide brushing software, so it is recommended not to brush the machine by itself. If there is a problem after brushing the machine, don't operate it yourself to avoid the problem expanding.
