It maybe that text notifications are waking up the screen at night. In that case you may need to completely disable notifications at night.
Some resolutions include:
- Turn off message notification completely
You can stop the screen from turning on when you receive a message by disabling the message notification completely but you lose all the notifications, including audio and LED flashing alerts.
Depending on your device, navigate to Menu > Settings > Notifications and turn off.
- Turn on Do not disturb feature (Android 6+ )
Do not disturb is a feature that lets you silent all notifications for a specific time period. You can choose to allow messages and calls from select contacts to still alert you when Do not disturb is enabled.
Open the Settings >> Sounds >> Do Not Disturb setting. On the Do not disturb settings screen, tap Block visual disturbances.
You additionally need to turn on the Block when screen is off option.
- Using third party apps
Some users claim that apps such as I'm sleeping have the ability to prevent screen wake-ups at night. This app will automatically set your phone to silent mode during the night and optionally disables the LED during the
night
