I have critical apps that I need to run in the background; the BV9900 Pro (Android 9,US) force closes all my background apps when the screen is off.
I've whitelisted app the apps and disabled battery optimization on the apps I need plus one turned off Standby Intelligent Power Saving and still my apps get killed.
Apps like WeChat, Notify and Fitness (for Amazfit smartwatch), etc get closed and I miss my messages.
Please help! Thank you!
