If you're looking for a way to keep your phone within easy reach while you're in the shower, a suction cup mount is a great option. Here's how to use one:
First, make sure that the surface you want to attach the mount to is clean and dry. Then peel off the backing on the suction cup and press it onto your skin. Once it's secure, press your phone into the mount. If necessary, adjust the position of the mount until your phone is at a comfortable viewing angle.
To remove the mount, simply peel it away from your skin. If there's any residue left behind, you can clean it up with soap and water.
