Hi Dolph,
since the 3.5.388 update some of us have an annoying bug where all the apps are killed at night time even if they are in all the "white lists" and power optimization is OFF. So at night no more messages from Whatsapp, reminders, alerts (like MyPillbox). It doesn't happen with the system apps.
In my opinion it is due to the "nighttime extreme power saving" ZUK introduced that is not well managed and overcome any other setup.
I'm not rooted and looked.
Do you have feedbacks on this issue with the latest firmware?
Thanks, ciao
I have DND mode enabled at night. But apps are still alive in the morning. I also get push messages from WhatsaApp. Experiencing some issues with push messages from Gmail and Threema but apps are not killed at night. Battery drains about 6-10 % at night with Spotify enabled for podcasts

trying now. takes some time to set up google contacts sync.

feels more fluid and slightly more mature as a ZUI. however lots of cosmetic refinement missed (hence DEV)

no problem with widgets except if you install 3rd party launcher, stock apps widget not available.

it is possible KEEP widget is not available on ZUI, as it wasnt avail on MIUI as well.

can see some similarities in features on ZUI to MIUI

not much heat, things run pretty smooth. not sure about lag / hang will monitor along with battery drain.

is there any way to disable the navigation bar?
