Launcher preference not persistent between reboots

Question

I recently purchased the BLU Vivo One Plus 2019, which runs Android Oreo (8.1). After installing kiss launcher and setting as my default launcher, I rebooted my device and the launcher reset back to the pre-installed Launcher3. Note that my other default applications remain, for example I also changed the default messaging app to Signal.

Are there any workarounds for this? How can I retain my preference for the default launcher?

Answer 1

Based on this answer,

adb shell cmd package set-home-activity "fr.neamar.kiss/.MainActivity"

However, this only works from an external device.
