Apk not installing on 3.0

[Nes]

I have S10 lite and after updating to 3.0 unable to install apk. Is there a solution? 

[Anikroyale]

I am sorry, but I cannot think of any other reason as to why APK installation is blocked by secure FRP.

[Anikroyale]

Well, I consulted with my team and I found out that F-Droid is not yet compatible with Android 11 and is under development.

Not only fdroid, I am not able to install any of the apk's

Also if you are working on 3.0 and s10 lite or any galaxy please confirm that if you are able to install apks

[Anikroyale]

I am currently not on Android 11, but it should not be the case. Are you getting the same error while installing other APKs?

[Nes]

Yes

Fdroid doesn't support Android 11 properly according to your logs. So it will not install properly w8 for Fdroid team to update their repos according to android 11 and one ui 3.0

Not only fdroid, I am not able to install any of the apk's. Also if you are working on 3.0 and s10 lite or any galaxy please confirm that if you are able to install apks

I don't have any devices with 3.0 right now that's why can't confirm

Yes I am on ONE UI 3.0 on my note 10+ and I can install apps.

Meanwhile you can try one thing.

Goto Settings 》 Apps 》 touch 3 dots on upper right corner and reset app preference.

After it when you try to install any apk you will get two options one will be package Installer and one another.
Try to select the other option and update me if that works or not.

One more thing I would ask you to try is try installing any other apk and chk.
