Hello i have bought from banggood power 6 with Android 9. I have some problems. First i set up a live wallpaper which is an automate wallpaper changer. After reboot lost this wallpaper and put the factory one. Same with widgets after reboot none of them works and have to set up them again. Third many apps need accessibility on but when i activate them after all are deactivated by themselvesself. And last in notification bar some apps need to be run such as weather but after some time close. I know there is something about battery optimization is about and duraspeed but how can i deactivated? Please help me cause device is totally useless
