### 5/5 — The best

### 5/5 — Thanks guys

*2026-08-20, version 1.5.8*

omg my phone had so much water at the bottom and I remembered this app and it worked well so here’s a 5 star rating and review

### 5/5 — Amazing the best thing I ever downloaded

*2026-08-19, version 1.5.8*

I got water in my phone and it was making weird noises,and the moment I download this app I used and it, instantly it fixed my phone.

### 3/5 — Mad

*2026-08-18, version 1.5.8*

### 5/5 — Sr

*2026-08-11, version 1.5.8*

### 1/5 — App might be malicious

*2026-08-10*

Might be a coincidence but since I used the app the following things have happened: my speaker has kept randomly crackling, my phone screen went green and glitched a lot, my phone has been really slow (kicking me out of apps and screen staying black for ages before loading), and my phone went down over ten percent in less than a minute. Additionally, the ads are misleading as it showed dust coming out of the speakers even though that’s not what the app is intended for which lead to me downloading it when I didn’t need it in the first place (for clearing dust from my speakers). Just in case my experience is a result of the app, I’d recommend using an alternative.
