Update or reinstall the MMY APK

Updating MMY depends on the version code, not the version name. The file measured on 10 November 2026 carries version name 2.2.5 and version code 225.

Installing over the same app

Android accepts the new file when three things hold: the package name matches com.mmyuionn.opp02, the signing key matches, and the version code is higher than the one installed. Your data stays. If any of the three fails, the installer says "app not installed" and changes nothing.

When the version name looks newer but it will not install

A file labelled 2.3 or 3.0 can still carry version code 225 or lower. Android compares the integer, ignores the label, and refuses. Ask the page you downloaded from for the version code, or dump the file yourself. A higher label with an equal code is not an update.

When a different MMY is already installed

The other file measured the same day, mmy.apk at 21,049,457 bytes, uses package com.Mymuqiueb.ineb. Same version name, different app as far as Android is concerned. Installing the channel file beside it gives you two icons named MMY and two separate sets of data. If that is not what you want, uninstall the one you no longer use first. Uninstalling deletes that app's local data, so move anything you need out before you do it.

A clean reinstall

1. Open Settings, Apps, MMY. Note the version shown.
2. Uninstall. This removes the app's stored data on the device.
3. Download the file again and confirm it is 20,954,528 bytes.
4. Install, then open it on Wi-Fi so the first launch can fetch its assets.

Reinstalling does not move an account from one package name to the other. If you used the app under com.Mymuqiueb.ineb, the login lives with that package, and only the app's own account recovery can carry it across.

Storage after several updates

Each install replaces the previous code but cached assets accumulate. If the app grows far past the download size, clear its cache from Settings, Apps, MMY, Storage. Clear cache keeps the login. Clear data does not.
