I’ve managed to get a fairly standard TPU case from Amazon, which will do the job for now. Usually I design my own custom (Prince themed) ones from Casestation, but last I looked they didn’t have P6Pro ones available yet.
The slipperiness wasn’t an issue in-hand. But when placing the phone down on a variety of surfaces (even relatively flat ones) it just wouldn’t stay put. Even on the couch it seemed to have a life of it’s own and migrate itself down the sides of the cushions The case has solved that though for sure.
The camera is mindblowingly good!
