Root Checker 6.5.11 for Android

Root Checker 6.5.11 for Android is a free app by JoeyKrim that answers one question: does your phone have working root access? This version is dated 16 September 2026.

It is the tool people install right after trying to root a phone, and also before buying a used device that should not be rooted at all.

Quick facts

What the app checks

Rooting tools often report success even when something went wrong, and a phone can also be rooted without the current owner knowing, for example when it was bought second-hand. Root Checker settles the matter. It looks for the files and permissions that root access leaves behind and then tries to use them, so the result reflects what really works, not just what is installed. The answer is a clear yes or no on a single screen, along with basic details about the device and its Android version. That is useful after using a rooting utility, before installing apps that require root, and when support for a banking app insists your phone looks modified. It does not change anything on the phone and does not try to root it; it only reports what it finds.

How to use Root Checker

1. Download the app from the developer's site, joeykrim.com, or from an official store listing.
2. Open it and accept the short introduction.
3. Tap the button to verify root.
4. If a root manager asks whether to grant access, allow it for the test.
5. Read the result: green means root works, red means it does not.

Is it safe?

Yes, as long as you get the genuine app. Root Checker only reads information and asks for root permission solely to test it. After the check you can revoke that permission in your root manager.

Is it free?

The app is freeware; the basic check costs nothing.

When the result is unexpected

A red result right after a rooting attempt usually means the exploit did not work on your model or that a system update closed the gap. A green result on a phone you never rooted is a reason to reset it or contact the seller, because a rooted device has weaker protection. In both cases, running the check a second time after a restart helps rule out a one-off glitch.

Requirements

Any Android phone with a little free storage. The check is compatible with rooted and non-rooted devices alike, which is the point.

Pros and cons

• Clear yes-or-no answer in seconds.
• Read-only: it changes nothing on the phone.
• Does one thing only.
• Cannot fix root problems it finds.

If you are rooting a phone, run it last, after the rooting step is finished.
