one ui 3 update, has deleted apps

[griffo83]

As soon as my device did system update it deleted apps off my device and I can not install them from playstore it just comes up as app not installed and I can't uninstall the update. How can this be fixed

My device is s20+

I have spoken to Samsung and they was unable to fix the issue they suggested sending my phone for repair which I do not want to do as nothing is wrong with my phone just this stupid update they have sent out

I fixed the important one for me which was life360, for somer eason apparently the apk remains "installed" but no traces of it are found, so I uninstalled it through ADB and was able to install it again.

**Step by Step**

1. Install USB drivers for your Device
2. Download and Install ADB tools
3. Enable[ Developer Options](http://wccftech.com/enable-developer-options-android-nougat/) and [USB Debugging](https://technosamigos.com/enable-usb-debugging-on-android-nougat-phones/)
4. Find a good USB cable, plug it into your computer and then to your device. When the pop-up appears asking you to authorize the device, allow it.
5. Open a command prompt (cmd in windows) and type:

adb devices

6. This should return the ID of your device. If not, please go back and retrace your steps.
7. Now type:

adb shell

8. Use the following commands to find the apps you want to disable (replace 'amazon' with the manufacturer, i.e. 'samsung')

adb shell cmd package list packages | grep 'amazon

9. This should give you a new prompt, something to the effect of (device-model):/ - here type the following:

pm uninstall -k --user 0 <name of package>

This should return 'Success' at which point the package has been removed!

I created a thread on reddit and someone posted a reply for the Spotify app at least:

Can't install Spotify on Android 11 / One UI 3 : galaxys10 (reddit.com) 

It does include installing a cracked app. Uninstalling it again, makes it possible to also download the regular version from the Google Play Store again.

I have the same problem with photomath, but this method does not work because the package of the app is somehow not installed (I searched for it with app inspector), and yet when I try to install the app again from the store or as an apk it gives me an error as if it is already installed.

That was exactly my problem, for some reason android 11 update with one ui 3 removed everything about the app but "something" remained which made it seem to the package installer that the app was still installed when in fact it was not, no trace of it anywhere.

The command should've worked. It works for system apps without Root.
