Good to know. I just checked and the Android 14 update is also available on the Onn TV HD stick as well - I am currently using 2 of those along with a couple of FireTV 4K Max sticks as my encoder devices. I was able to turn off auto-update for Apps but it didn't appear like there was an option to do this for system updates (like the Android 14 update), but it also seems like system updates require manual action.
UPDATE: One of my Onn 4K Pros appears to have updated itself to Android 14 - I am not using this with ADBTuner - I checked for system updates on this one, but did not update it manually, so I am guessing that if you check for updates, the device may become aware of the update and perform it automatically? unless you turn off auto-update for apps? (my Onn TV HDs have not auto updated)
UPDATE2: Looks like some of my other devices have auto-updated to Android 14 including an Onn TV 4K but the two Onn TV HDs that I am using w/ ADBTuner have not yet updated - one had an indication of "update paused" for some reason...
