Google's second son (Nexus S) has been used for children's shoes, and Android 2.3.4 has been released (although the official documents have not been updated yet, it may be less than 24 hours ), for Android 2.3.1, you must upgrade Android 2.3.3 to 2.3.4. By the way, this is an incremental upgrade, and the upgrade will not delete the original system and data (including contacts, text messages, and other content), so you can rest assured that the upgrade is complete.
Upgrade Method,
1. Put the file in the root directory of the internal bucket of your mobile phone.
2. Shut down, restart and continue to press the volume up and power buttons to enter the bootloader.
3. Use the volume button to select "recovery" and press the power button to confirm
4. when you see a triangle on the screen, press the power button and then press the volume up button. Then you can see an Option List and select Update file.
The upgrade process is about 1 to 2 minutes. Come and try it.
