Why can’t I receive push notification from Line application on Xiaomi Redmi 2? Normally, push notification is available when the chatting apps like WhatsApp, WeChat, Viber are in use or running in the back-end as background process. However, if you sign out or clear RAM of these apps, it might result of this unavailability of push notification. Seem like this is part of MIUI OS system behavior. Therefore, this issue might not be limited Redmi 2 only but all Xiaomi devices (Mi 3, Mi 4, Mi 4i, Redmi Note (3G/4G), Mi Note, Mi Note Pro) powered by MIUI 5 & 6. Anyway, there is a way to solve this problem.
MIUI added communication apps like WhatsApp and WeChat to have autostart permission in Security app automatically. However, Line app is not. Therefore, you have to add it manually. Just open Security app. Select Permissions, then Autostart. Check Line (or the app that you want). That’s it.
By the way, you might need to enable Show floating notifications (on lock screen or just everywhere else) too. To do so, go to Settings. Then Notifications – Manage notifications. Choose particular app. Check Show floating notifications then.
Well, you should be able to receive push notification from all your chatting apps from now on. Keep chatting…
