Fix BlueMail push notifications on Oppo and realme
Published
Menu names differ between software versions. If a path here does not match your phone, search your Settings app for the setting named in bold — it is the same setting under a different label.
ColorOS — and realme UI, which is built from it — keeps several separate switches for background work, and mail stops arriving if any one of them is off.
Allow auto start-up
Settings → Apps → App management → BlueMail → Allow Auto Start-up.
Some builds keep this in the Phone Manager or Security app under Startup manager or Auto-start management instead.
Allow background running
Settings → Apps → App management → BlueMail → Battery usage → Allow background running, and set power saving to Don’t restrict background activity (wording varies by version).
Turn off sleep standby optimisation
Settings → Battery → More → Sleep standby optimisation, where present. Like OnePlus, this is the setting that delays mail overnight rather than during the day.
If mail still arrives late
- Lock BlueMail in Recents so clearing the task list does not close it.
- Check Settings → Notifications and status bar → Manage notifications → BlueMail.
- If you use a battery saving mode, exempt BlueMail or turn the mode off; ColorOS power modes tighten background limits well beyond the per-app setting.
Push Settings for other devices
ASUS
ZenUI keeps an auto-start manager in Mobile Manager alongside Android's battery optimisation. BlueMail needs clearing in both.
Google Pixel
Pixels run stock Android, so two settings cover it: set BlueMail's battery usage to unrestricted, and stop Adaptive Battery from demoting it.
Huawei, Honor
Set BlueMail's App launch to manage manually and enable all three switches — auto-launch, secondary launch and run in background.
Motorola
Motorola runs close to stock Android: set BlueMail's battery usage to unrestricted and turn off Adaptive battery.
OnePlus
OxygenOS adds sleep standby optimisation and deep optimisation on top of battery optimisation. Turn off all three for BlueMail.
Samsung Galaxy
Samsung stacks three power savers on top of Android's own. Set BlueMail to unrestricted, keep it out of Sleeping apps, and turn off Adaptive battery.
