The Android update delivery system is not exactly a strong suit, as the availability of the updates also depend on the goodwill of hardware manufacturers. Especially when it comes to middle or entry level Android smartphones where post sale support is very limited or it simply doesn’t exist. It rarely happens for Android updates to be available but they don’t always get installed because they are not properly promoted.
Right now Android automatically sends a notification message when an OTA update is available. The second method is to manually check to see if there are Android updates using the Settings menu. But the precise location of the update page differs from device to device and not many users understand why it’s a good idea to update the Android version.
Google is very much aware of this problem and the father of the Android operating system is updating the Play Store app in order to be able to also deliver Android updates along with the regular apps updates. At the moment the information is not officially confirmed by Google and it was discovered based on evidence hidden in the 14.5.52 version of the Play Store Android app.
The main purpose of this change is to make it more conformable for users to update the Android OS but it may also create some confusion as most Android devices already have their own OTA updates sytem.
Basically, once an Android update is available all we have to do is go to the Play Store and tap the Update button so it can be installed but receiving two Android updates notifications might create some confusion for inexperienced users.
On the long term, maybe Google will integrate the Android update feature in the Google Play Store altogether so that Android OS updates can only be available through the Play Store.
