1. There are many apps on the app store which claim to boost performance, free up space, save battery, or optimize the RAM of your device. However, these apps interfere with other apps, like “K-9 Mail”, and prevent them from working correctly.
2. If you have any app like “Clean Master”, “Security Master”, “Task Manager”, “Phone Cleaner”, “Super Cleaner”, “Power Clean”, “DU Cleaner”, “DU Speed Booster”, “CCleaner”, “AVG Cleaner”, “Avast Cleanup” or “Norton Clean”, check that it doesn’t block or terminate “K-9 Mail”.
3. If unsure, consider uninstalling the app claiming to “clean” or “boost” your device.
