Modify/improve an Android system app

I have developed an Android app that needs to run on the device at all times and automatically start on boot. The app communicates with an API and performs some actions on the device that require root permissions.

The app works but there are stability issues (it crashes sometimes) and it doesn't start on boot.

The following things need to be achieved:

1. Reduce display brightness to a minimum to save battery

2. The app should be automatically on boot

3. The app should run stable at all times and not crash

4. The API access and workflow needs to be slightly changed

I am looking for an experienced Android developer as this app will be installed on 100+ devices and it is important to have a reliable app for this.

If you apply, please tell me about your previous experiences with Android apps and roughly what your approach would be to implement the required features.
