Get [Samsung] Respring old version APK for Android
Restart SystemUI.apk on Samsung devices using a Secure Settings exploit.
Using the Secure Setting "qs_tile_column", Respring can crash SystemUI by setting it to 0. This will crash SystemUI and right after, it will set it back to its original value. This method is safe, and it will abort if the device is not supported, therefore preventing any device incompatibility errors.
This is useful for applying SystemUI overlays, or just refreshing the UI cache.
