You might want to give the FLYGRIP a try. While the FLYGRIP doesn’t mean it will stick to you like a fly, it is a spring-loaded clip that attaches to a device or case. You can then insert a few fingers and still have a few fingers left to interact with your device.
Oh by the way, the FLYGRIP also works as a stand for your device in portrait and landscape model. You like apples? How do you like those apples?
Well, I am not certain if this device is for everyone, as it does increase the volume of your smartphone or tablet in a way where it could snag on your pocket. If you want it, here it is for $29.95.
