OTG (ON THE GO) functionality was originally supported by the bottom of Android mobile phones (Android 4.2 or above), but for various reasons, some manufacturers shielded the OTG functionality. So how can mobile phones without OTG function turn on OTG function? There are two ways for reference.

Android phones connecting to USB peripherals 

OTG makes it possible for Android phones to connect to USB peripherals such as U-disk, card reader, keyboard, mouse and so on. At the same time, it also makes it as convenient for us to operate mobile phones as computers. After connecting the mobile phone with the U disk through OTG data line, open the file manager of the mobile phone, then the mobile phone and the U disk can carry out data transmission.

1. Turning on OTG by adding code to the bottom of Android system

Most mobile phone manufacturers disable the OTG function by deleting the OTG code, which can be turned on by adding the support code to the system.

Step 1: To get root privileges for the Android phone;

Step 2: Install root explorer file management software;

Step 3: Open Root Explorer Manager, open system / etc / vold.fstab system file with text editor, write the following code to the file, save and quit and restart the phone to open the OTG function.
