I just bought a note3 dual-card dual-standby mobile phone, and sometimes I just use it.

According to your description, your note3 series mobile phone is stuck, and its response is slow. I suggest you:

1. Restart the machine to free memory.

2. In standby mode, press and hold the physical key in the middle of the phone for more than 2 seconds-select the lower left button in the pop-up interface-if there is an application running, select the right side to complete it all.

3. If an external SD card is inserted into the mobile phone, take it out and test it.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the problem still exists, it is recommended that you take the purchase invoice and maintenance card and send your mobile phone to the nearest Samsung service center for inspection and maintenance. Please visit:
