Extra Hz APK: questions and answers
Is there a version of Extra Hz for older Android phones?
The current version needs Android 8.0 or later. Version 2.2 is the newest listed build that installs on Android 4.2 and later. It is an old build: apps that rely on online services may no longer connect when they are this old. Get version 2.2 · All versions
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Extra Hz APK safe?
