[Vivo Nex Guides, News, & Discussion] blackinfinity:
As many people have know already, apps is still shutting down in aggressive manner even if they have been white listed. This is because there is a war between Vivos Imanager that try to shutdown everything to save power and androids own power management.

I will tell you how to stop the conflict between Imanager and Powermanagement, the solution is very easy but most people that complain have not noticed this detail.

This deserves its own thread cause this really solve all strange problems I have had with vivo nex (chromecast problems also solved now)

This is mainly important for push notification apps, video apps, and apps with chromecast ability.

We need to understand that Vivo have put their enchantments ONTOP of android, but android still is higher in hiracy but vivos apps trying to shut down stuff.

You must white list stuff both with the vivo settings and also android settings.

short repetition how to get push notifications work , you can either do it one by one in app info of each app or thru I manager and and permission manger)

Use whatever method you most comfortable with permission manger gives a good overview of app permissions.

Permission Push notification apps need is in app info screen

app Info/ Permission/single permissions: enable all in the device management section, autostart is the most important toggle. other options can depend on the app and its functionality but add permission to all in the top in the device management category.

App info/ notifications: enable the toggle as you desire decide if you want to see it on lockscreen, I can recomend to not enable "display notifcation details on locked screen" this is bad for privacy since people can read your messages if you dont guard your phone.

How to end the conflict between Imanager and Android Power mangement

As I said the solution is very easy but VERY important, since Vivos own software have lower hiracy in the system they Imanager and Android in conflict, this is why even though you have white listed everything in settings apps is still shutting down.

What you need to to is to go to control panel or task switcher and you will see a lock, if you doing it from the control panel which I recommend swipe down on the app you want to let stay in memory and not shut down out a lock on it. Now apps will not shut down, this is required for push notifications to work as intended also this must be enabled for all apps you want to chromecast from otherwise you will have to reload the app you casting from, this was a big problem with youtube before I was going back to the app and it was reloaded. This detail is very important and this is simply very bad design by vivo, since you basically have TWO power mangement systems in one system that dont work with each other. Now when I have added lock on all push notification and chromecast apps all seem to work just as good as any other phone. Keep Google app with lock on and home app on too if you want to make sure chromecast work, if you cast from browser then put lock on it too. Its easy to put a temporary lock on apps in control panel so you dont have to have it memory permanently keep in mind, also, you can shut down apps in task switcher...lock is only active as long as the app exist in task switcher.

Do you have problem with google sync services you can add apps in Imanager/autostart/startup( at the top)

Startup permission means (allow startup by other applications) When looking in the start up records screen it seem it is mostly the google sync services that want to start/awake other apps, if you have any specific problem that you think is related to google sync service enable, personally I have not enabled it cause I think the battery will take a big hit cause I see the android sync serivces want to wake up apps a lot. If Android sync service is for some how very important for you then enable it, but personally I think that the syncing is restricted is one of the reason why Vivo Nex have better battery then most.
