v2.4.4[SDK36]: Apps section is CRASHY on A16/OUI8. f-print sensor unlock problems. very useful inspection tool, not limited to devs. there are so many andro settings & they routinely get flipped w/o user knowledge &/or consent. this isn't a change monitor, but knowing what to inspect tells me what to fix.

Hi Roy! Is it OK to say that I love you? Here is the deal: Samsung A5 2015(2016) mobile non-upgradable to the 7.1 version of android. Lots of space in the SD card but no "Developer Tools" possibility in my Settings. Internal memory constantly hitting the 96%-97% because I was crazy enough to set WhatsApp to back up 5 days rolling. Other "move to SD" apps installed before, but they would not touch Apps built as "non-movable" - such as WA. And there you come with this jewel. It will still not touch the useless core apps (for me) such as Samsung Health, Samsung Pay and Word, but it does a hack of a job on all the others we have downloaded ourselves and which developers had not been so kind to set as movable to SD. So all that "beginners" as myself need to know, is that they should tap Developer Options once the Developer Tools App is open, scroll all way down to "Force allow apps on external" and then they go to their Apps management windows in Settings, pick app, storage and see which has the change button available. And move them to SD. WA tested and works perfectly. So now just going down my list. Thank you. <3 this has been a hard one to crack for a while.

DO NOT install ANYTHING that this HACKER develops. I installed this app less than a week ago, and uninstalled it the next day. Then I noticed it was back among my apps! From that point on he's been hacking my phone, my wifi EVERYTHING. Google needs to do something. This guy is a predator.
