Extra stats not working on Samsung Galaxy S23 Ultra. Not sure why, after granting the appropriate permissions the app completely breaks itself and refuses to launch, for what I can identify as no reason, since it worked the first time. I restarted my phone, and the entire app came crashing down on itself. Until a fix is issued, I can't recommend this app.

I love all that this app does in its monitoring. Battery temperature, signal strength, other things such as the display using the battery, etc. It's cool to be able to open the app and see how all these affect the battery drain. One thing I've noticed recently is that there's an option to show a notification, but there is no notification showing at the bottom of my notifications like I'm used to.

GSAM is great with ADB-enabled permissions, but it constantly shows different apps — keyboards, Gcam, etc — draining battery when idle with "video on" stat. I've no idea what it is for most of them, but this "video on" thing keeps on sucking charge out even after I reboot, kill and clear data/cache for those apps or even restart my phone. The only thing that works is to delete and reinstall the app. Could you add more information on 'video on' stat, how to deal with it, please? (SG Note9 Exynos)
