About this app

This app is for advanced users to set the roaming threshold. You can force your device to only connect to 2.4G or 5G. Or set the roaming parameter such that it always attempt to connect to a good network or only roam to another network when signal is weak.

In order for this app to function please run the following ADB command:
adb shell pm grant com.catech.wifiroamconfig android.permission.WRITE_SECURE_SETTINGS

***UPDATE***
For Android 13 or above

You might get "grantRuntimePermission Security Exception"

To solve this security exception problem, go to Developer Options and scroll down until you find "USB debugging (Security settings)". Enable it and the issue should be resolved. Please check the above screenshot. I hope this helps and if you found this solution useful, please consider leaving a positive rating. Thank you!
