Redmi 2 supports OTG function, and the following settings can be used:
1. Since the OTG function in MIUI is disabled by default, the user needs to enter it in the system folder of the phone. Create a etc folder by yourself, and then search online to download a file VOLD.FSTAB that enables the OTG function in the Android system.
2. OTG can be used, but for now, it supports recognition of 64G FAT32 format U disk by default. Larger users can try it.
3. Due to Google’s patent purchase issue, the Android OTG function cannot recognize NTFS formatted USB flash drives by default. If you want to recognize it, you need to root and change the system files, and then it can be solved.
