This will only work on Android 8 and above.
DJI drones operate under two major sets of regulations:
- FCC (for US, Canada and a few other places)
- CE (for Europe and most other places).
Because CE regulations are much stricter, the drone needs to turn its radios way down, from an FCC allowed noise of 26dB on 5.8Ghz all the way down to 14dB for CE, which is a very big difference given the logarithmic nature of the dB scale.
For Ocusync 2.0 drones (Air 2, Mini 2, Mavic 2) for example, this drops the maximum range from 10km to 6km and offers much less stability at close distances when going behind obstacles like trees or houses or when flying in area with high interference. The 5.8Ghz band (mostly used in urban environments) is even more limited than the difference in maximum range (obtained in 2.4Ghz) would suggest.
The FCC mod allows the drone to bypass these restrictions and turn its radios to full power.
Furthermore, the FCC mode enables frequencies that are disabled in certain countries (e.g. 5.8Ghz is re-enabled in Russia and Israel).
If you are already flying in an FCC country (e.g. U.S. / Canada), this mod won't do anything for you as your drone is already transmitting at full power. The only reason to get it would be if you're planning to travel abroad.
Please be aware that turning up transmission power without specific permission from the competent authorities as well as flying outside of VLOS is illegal in most places. We encourage you to always follow your local laws and regulations.

FCC mod for DJI GO4 for Android
HOW DOES THIS WORK?
The FCC mod will install as a separate app on your Android device and there is no need for your device to be rooted. You will however need to uninstall the official app before installing the FCC mod.
The app will be delivered to you via a link. That link will allow you to download an APK file, which you can then install on your device following the normal procedure for installing an app on Android devices.
Please note this app is not compatible with the DJI Smart Controller or with the DJI RC Pro. It only works on normal Android phones and tablets.
The app can be used with an unlimited number of drones.
UPDATES & SUPPORT
The license is valid for one device, with free updates included, for 12 months. Updates will be released a few days after DJI release their update, provided they don’t make some drastic changes that completely break this mod.
It is guaranteed that the current version of the Fly app will switch the drone into FCC mode on the current firmware of all supported drones. We cannot be sure what will happen in future firmware updates, so you will be performing these updates on your own risk (although unlikely, the FCC mod could be lost on such a firmware update).
The app is guaranteed to work on all public Android versions that the official DJI app is working on. If you are using it on beta Android versions, you are doing it on your own risk.
