If you have a lock code or pattern set, you will be prompted to enter it before 

proceeding with the formatting. 



Once completely formatted, the card is automatically re-mounted (reconnected for 

use by the device).

The formatting procedure erases all the data on the microSD card, after which the 

files CANNOT be retrieved. To prevent the loss of important data, please check the 

contents before you format the card. 

Control your device’s data delivery and battery usage through this settings menu. 

Active applications, light levels, Bluetooth usage, and GPS functionality all act to drain your 

battery. The following is a list of helpful tips that can help conserve your battery power: 

●  Reduce your backlight on time. 

●   Turn Bluetooth off when not in use. 

●   Turn Wi-Fi off when not in use. 

●   Turn 4G off when not in use. 

●   Turn off Sprint Hotspot (Wi-Fi hotspot) services when not in use. This is one of the 

largest drains on your battery as it is not only transmitting a Wi-Fi connection to your 

device but is also doing it while using a 4G connection.
