Security & authenticity

Security rating: Trusted

Signing certificate

  • Certificate issued to “Tapas Mobile” Not the developer's name (“duapps”). Names in certificates can't be verified, so this alone proves nothing.
  • Same certificate as the 2 other versions checked

Store checks

  • Developer signature verified Apr 3, 2016
  • Antivirus scan passed Jan 16, 2020
  • Uploaded by “neymarjn” 323 followers · uploading since 2016

Scans come from the source store; the certificate comparisons are AAPKs's own, made from the files' published signatures (2 other versions compared). AAPKs doesn't scan files itself.

How to install DU Battery Saver on Android 2.3+

You'll need about 12.6 MB of free space.

  1. Download the APK — tap Download APK above (6.3 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
  2. Open the file — tap the download notification, or open Files › Downloads and tap com-dianxinos-dxbs-5031-18485129-beb35b475a552cf6d6a0ba20c8d3c81c.apk.
  3. Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
  4. Check the file (optional) — the MD5 of the downloaded file should be beb35b475a552cf6d6a0ba20c8d3c81c. If it differs, the file is damaged or was changed: delete it and download again.
  5. Tap Install — Android asks “Do you want to install this app?”. If Google Play Protect shows a warning, read it before you continue: the source store rated this file Trusted, but only install apps from sources you trust. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
  6. Open DU Battery Saver — tap Open on the install screen, or find it in your app drawer.
Common install problems
  • “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
  • “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 2.3+). Download it again, or pick an older version.
  • Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
