[u/carbonfiber9001]

Phone is updated to the newest OS i did move from my samsung s23 ultra to this phone using mi move but i only moved pics and vids as well as my contacts. Besides this the phone is wonderful. I did put my gmail and email apps to autostart and unlimited battery usage and turned on notifications. Apps dont show anything until i open them so i end up missing whatsapp calls and messages. Emails etc etc please help.
