Release build config

I am deploying release build with AOT true using visual studio to my android phone is loading very fast(4 Sec).
But same configuration of release build with AOT true I am uploading to playstore and downloading to my same phone is loading slow(11 sec).

Why apk deploy using visual studio is loading fast?

Thank you for the report!

I believe that you might be running into the following issue:


In which we had recently found the cause of this:


As for the loading differences, there shouldn't be a difference between the APK you upload to the play store and the apk you install on your device given they were both built using the same configurations. Some items that you might want to consider is using a fresh device (One that has never been used to debug) and install both APKs to time the differences. It's hard to know what the exact case is here as we do not have the APK in question to compare against your Release APK. I would also do a comparison of these two APKs to ensure no settings were changed between the Release -> Store APK. If you have these APKs that we can investigate further with, that would help aid our investigation.

Thank you!

Tomorrow it was slow. Today I reinstall the apk from store and its loading fast. 6 Seconds compare to 11 seconds without AOT. I will check on more device.
