App not installed error

[AbishekNaagendra]

I'm getting the "App not installed" error when I try to install APK files in my Samsung Galaxy M51. The same apps are getting installed in other Samsung devices sporting the same Android 11 version. Is it due to app signature? Is there a way to resolve this issue from the device itself without signing the app?

Samsung apps will not install unless they are made compatible with OneUI core,
Even you can't update samsung apps manually in 💩core

Not just with Samsung apps. I just took it as an example. I'm facing this error across many other APK files.

[IcyJay30]

Any other example?

Many apps that aren't in the Play store - Some of my company's apps(until it's signed), some Government apps, some streaming apps that aren't for Indian users(like Hulu/Paramount+), some ported/mod apps(like GCam)

Maybe sai (split apk installer) will help.

Samsung internet beta isn't compatible with One UI core or basically M series devices.

I know. But, it's the stupidest thing I've ever seen/heard. I can understand that M series phones don't support CA or Samsung Pay. But, the fact that M series phones support Samsung Internet but not Samsung Internet beta is beyond my comprehension. 😕

Apparently to justify the price difference between A series & M series devices, Samsung pretty much disables/lock features. What can I say? Btw if you're hellbent on trying to install the beta, you can try using lucky patcher. Check one of my friends Rufus's post:

How can an application in beta version be considered a feature? Chrome, Edge, Firefox, Opera, UC etc. offer beta, Dev and Canary versions with more advanced features without any constraints. Besides, Samsung Internet Beta isn't the app I'm "hell bent" on installing. I'll this lucky patcher with my company apps though. Hope it'll work. Thank you.
