my Nubia z17 (nx563j) does like follows:
a) on standby mode and lockscreen
When receiving an eMail with the K9 app, the phone LED blinks one time and the vibration occurs.
Following the phone does a reboot (software reboot) so that you have to authorize again.
After the reboot there is no sign in the notification bar, but when opening K9 app, the message is available.
b) on active mode
When receiving an eMail with the K9 app, the phone LED does not blink and no vibration occurs.
The letter symbol occurs in notification bar, sometimes a reboot follows.
I’m using MK71.2-nx563j-201711201446-NIGHTLY.zip, further versions I’ve tested have same behavior.
Anyone have same problems ore solutions?
Thanks a lot,
