Push Notification Issue HTC One GPE 4.4
Hi all, since two days i have a big problem with my notifications. When i get a WhatsApp my Phone rings/vibrates. LED indicator ist also working. When i unlock my phone then i can see the notification for the new message. But only for about an half second. Then the notification disappears.
BUT: When i close the WhatsApp App by pressing the back-button until the App closes it works propely and notification is in the notificationbar till i open the app and read the message. Itīs only when i leave the app with the home button.
Same problem with e.g. Google Hangouts and K9.
What i tried:
- Reboot phone
- Reinstalling the apps (Whatsapp)
- Viped cache (TWRP)
My phone is a HTC One (originally TMO) running KitKat (4.4), rooted, S-Off, CID changed (for installing GPE 4.4)
Anyone an idea?
