Suddenly some sort of "control panel" has appeared on my S7 Edge. It works the same way as the drop down panel from Samsung, but this time it is from the bottom. I have searched all over internet to find a solution and cannot find any. The "control panel" app cannot be found in the application manager and it also shows in the lock screen if it is not hidden before the phone goes into stand-by.
The control panel looks like this, and if I press the rocket ship it launches and says "Cleaned up Memory XXXMB!":

Please, can anyone help me to remove this? I believe that this is also the root to the problem I have with "Screen overlay detected". The issues with "screen overlay" is not solved even if I disable all programs (that can appear on top), not even if I also disable the system apps. This means that I cannot set any permissions for any applications (such as allow Telegram to access photos etc.).
