Apps recently changed, without an update from the store
You can check that using ADB

List the first install time:

for package in $(dumpsys package | grep -Po &quot;Package \[\K[^\]]+&quot;); do
    echo $package $(dumpsys package $package | grep firstInstallTime)
done;


last update time:
replace firstInstallTime with lastUpdateTime

If theses Apps changed they will not receive the updates from the Play Store as the signing certificate will also change. To ensure that it's the same app from the store:

dump the APK from your device
Download the same App from the Play Store in another phone or from APKPure
use aapt2 to compare these Apps:

$ aapt2 diff apk1 apk2

or you can also compare certificate of both Apps.
