I just wanted to add a few things... 1. Despite the name and author's description, this app does NOT require a firestick, it will work on any android device that meets its prerequisites...obviously needs adb debugging so would be extra work before android 11 and wireless debugging, but I've tried it on 12 and 14 and i worked great. 2. Here is an example of what I'm using it for RIGHT NOW, but I have much more planned for it in the future. Here is my current command string: cd /sdcard ; /system/bin/nohup /data/app/~~8oxXZxJ4kEGCeEJWqreGrg==/moe.shizuku.privileged.api-fYJFHd8-ecqDItmvycyLOw==/lib/arm/libshizuku.so & logcat -d --buffer="main,radio,events,system,crash,stats,security,kernel" --format="long,descriptive" --dividers > /sdcard/logcat_all_at_boot_bandw.txt This saves the logcat output to a file as soon as possible after boot, trying to capture the very beginning of the logcat (to gather info for eventual rooting attempt) and also ensures that Shizuku's server is up and running immediately after BOOT_COMPLETED. Good luck and let us know what YOU have used it for, please so we can all learn new things! Peace.
