Performance is WAY TOO SLOW on my Samsung On5 Phone

The Prey application is running WAY TOO SLOW on my Samsung Galaxy On5. It’s not a flagship phone. I realize that but for Gods sake, should it be this horrible? I literally have to wait about 1 or 2 seconds after typing each letter of my password for my phone to catch up before I can enter the next character in my password.

If the developers are reading this, please give an option to turn off that animation on the log-in screen. It’s killing the performance. Unless, my phone is doing something I don’t know about behind the scenes.
