hi so recently I got a new phone a Redmi note 13 to be exact and I'm encountering an error installing apps as it shows apk not installed always I can't also transfer files to data folder as it's missing more or less there are apps I wanna installed but its keeps on showing " app not installed no matter what I do"
how should I know if it's rooted? also another question i checked the version it's hyper os and I gained access to developer options they say miua optimization is the cause but I can't find it in my phone lol
If you are asking if your device is rooted, I am 99.99% sure it is not, optimization miui this is a hidden function, you need to go to the developers menu, scroll to the very bottom and find the item "Reset to default values" click on it a couple of times, and a little below the system optimization item will appear

I had a similar issue while installing Brawl Star's APK, and after some troubleshooting, I found a method that worked perfectly. First, ensure the APK file is not corrupted by downloading it from a reliable source and checking if it's compatible with your device (32-bit or 64-bit). Next, go to Settings > Apps > Special app access > Install unknown apps and allow installation from your file manager or browser. If your phone still shows "App Not Installed," try freeing up storage space, restarting your phone, and disabling Google Play Protect from the Play Store > Play Protect > Settings to prevent installation blocks. Since you also mentioned the Android/data folder is missing, you might need a third-party file manager like X-plore or ZArchiver to access it, as newer Android versions restrict modifications in that directory. If all else fails, installing the APK using ADB (Android Debug Bridge) on a PC could bypass system restrictions. Let me know if you need help with that!
