Can I remove the phone cover with isclack or suction cup without removing the screen protector glass first?
short answer , yep just did it
if you are carefull enough then it is possible, when you have lift the front put some thin knife in the gape between front and housing at the bottom.
My preferred method would be to use the iSclack to get in-between the frame and the screen just enough to get a pick under the screen. Then use the pick to loosen the clips. Works every time even with screen protectors.
