This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.
Quick take
The Lamicall Shower Phone Holder is a waterproof shell for your phone that hangs on a wall hook in the bathroom. iPhones are water resistant, so why bother? Because my iPhone lives in a leather case I don’t want soaked every night, and I would rather not expose the phone to steam every day either. For watching videos or playing music in the shower or bath, it works well.

What I tested
- Lamicall Shower Phone Holder (comes with three adhesive wall hooks)
- iPhone 17 Pro Max inside the holder
- For comparison: the Teresa waterproof iPad case I have used almost daily for a year
What I found
- Face ID works through the cover, and touch input is fine for browsing and play/pause, though your finger doesn’t glide as smoothly.
- Position the phone slightly high. If the bottom of the screen sits right at the frame edge, the home swipe and app switcher become unreliable. A Pro Max fits, but only just.
- You can’t press the volume buttons, so pair it with a waterproof speaker.
- Glare is noticeable at an angle but not when viewing head-on.
- Three ways to use it: hang it on the wall hook, stand it on a surface with the extendable back, or rotate it to portrait on the hook. It can also tilt forward and upward.
- The hooks match my Teresa iPad case. Different brand, identical hook shape, so the phone holder hangs on the double hook I already had on the wall for the iPad.

iPhone holder vs. iPad case
| Lamicall (iPhone) | Teresa (iPad) | |
|---|---|---|
| Hooks included | Three single hooks | Two suction-type double hooks + one magnetic |
| Angle adjustment | Rotate, pull forward and tilt up | Ball joint, much freer |
| Tabletop use | Extendable back | Fold-out legs |
Who it’s for
People who use a leather or fabric case, mostly watch videos or listen to music in the bath, or already have an iPad shower case on the wall. If you type lots of messages in the bath, you will probably find it easier to take the phone out.
Watch the review
The video is in Japanese. Useful parts: around 3:00 fitting the iPhone and touch response, 5:30 the shared hook with the iPad case, 10:10 mounted in my bathroom.
Limitations
I would not treat it as fully waterproof: shower spray is fine, but don’t submerge it. The price was ¥1,699 on Amazon Japan at the time of recording. The Teresa iPad case may be hard to find outside Japan.
