About Phone Cleaner-Master of Clean
I have an older Android phone that’s always running out of storage, so I’m constantly on the lookout for a good cleaner app. I saw Phone Cleaner-Master of Clean with high ratings and decided to give the free version a try. My hope was to clear out some cache and junk files without too much hassle. Unfortunately, my experience was frustrating from the start, and I ended up uninstalling it after a couple of days of testing.
Features & Highlights
The app promises a suite of tools: a junk cleaner, phone booster, battery saver, and even a CPU cooler. On paper, it looks like a one-stop shop. I tapped the big “Scan” button on the main screen, and it quickly claimed to have found over 2 GB of “junk files.” That got my attention. The battery saver feature shows a graph of your usage, and the CPU cooler has a little animation of a thermometer going down. However, I noticed the “deep clean” and “security scan” features immediately tried to push me toward watching a full-screen video ad before they would run. The app manager is basic, just listing installed apps, and the file manager felt like a stripped-down version of what’s already on my phone.
User Experience
My first red flag was the immediate pop-up ad right after the initial scan. I couldn’t even see the results before being prompted to download a different game. Navigating the app feels cluttered, with flashy buttons and exaggerated warnings about my phone’s “critical” state. When I tried the “Phone Booster,” my phone actually stuttered for a second while it closed background apps—the opposite of a smooth boost. The worst part was the notifications. Even after I cleaned what it suggested, I got multiple alerts a day saying things like “Your phone is 85% damaged! Tap to fix.” It felt predatory and designed to scare me into interacting with the app constantly.
Pricing
The app is free to download and use, but the “free” experience is buried in ads. You get a video ad after almost every action, plus banner ads on every screen. There’s a premium version advertised to remove ads and unlock “advanced” features, but given my poor experience with the core functionality, I wouldn’t consider paying for it. The constant upselling makes the free version almost unusable, so it’s not really free in any practical sense.
Updates & Support
Looking at its update history on the Play Store, the developer pushes updates fairly regularly, about once a month. Most of the notes are vague, like “performance improvements and bug fixes.” I didn’t find any obvious contact method for support within the app itself. The help section just links to a generic FAQ. For an app that performs “security scans,” the lack of clear developer contact or detailed update logs doesn’t inspire confidence.
Security & Privacy
I downloaded this from the official Google Play Store. Its privacy policy, which I had to search for online, states it may collect device ID, advertising ID, and usage data. During setup, it asked for permission to access photos, media, and files, which is expected for a cleaner, but it also requested “accessibility services.” I denied that one, as it seemed unnecessary and invasive. The security scan feature felt like a gimmick; it scanned for a second and declared my device safe without explaining what it checked. With the amount of ads and potential data collection, I’m not comfortable with its privacy stance.
