this app killed the kernel in my phone and basically bricked it. It might have to do with twrp recovery interacting with the app but I don't think so. I would say don't get this app if you have had issues with your recovery before. But I'm still not sure why it completely killed it. Might have something to do with Samsungs software screwing with it.
My phone will not work anymore because of this app 😭
Simple and does what it says
API 27 update
Simulates a reboot and thus frees up memory - your phone will be much snappier!
