oppo u705t’s phone is very stuck recently, and when someone sends me 5 or 6 text messages, what’s going on? what to do?

Hello,

According to your situation, there may be a problem with the phone's firmware. You can try to double-clear your phone and see! The specific steps for double clearing are as follows: After shutting down, press and hold the power button and the volume down button at the same time. After 5 seconds, enter the recovery mode - the recovery interface appears, use the volume up and down buttons to select "Clear Data/Restore Factory Settings", use the power button to confirm and wait for the end - use Use the volume up and down keys to select "Clear System Cache" and the power key to confirm and wait for the end, and finally select restart. Note that Double Clear will clear all data, so be sure to back up important data in advance! ! !
