Samsung Galaxy S6 Edge — HELP: stuck in Smart Switch mode

Need serious help. My Samsung Galaxy S6 Edge is soft brick I think.
I was able to go into recovery and download mode (VOL DOWN + POWER + HOME keys).
Now it's currently stuck in Smart Switch mode.
I cannot take out the battery so the phone cannot be switched off that easily.
Does anyone know how to get out of Smart Switch mode?

Solved it.
Apparently need to connect the phone to USB/PC - then can use the VOL DOWN + POWER + HOME and it works, can get into the recovery menu and select Download mode.
