I bought a leg holder for my phone, but it keeps slipping down, so I never use it. Bought one of these vests, since it had the pocket, but the pocket is too small for my G4 phone. It will fit one of those flat LED lights and/or keys, though. So not a total loss.

I’m thinking I might have to drag out the sewing machine, since my next phone will be even bigger.
