You have heard that the latest version of Android OS is available. It has been weeks, maybe even months now, since it has been available. Despite the fact that you have enabled auto notification of updates on your device, you are stuck using it without the latest features because it is yet to receive the update. Why?
The fault isn’t that of Alphabet (formerly known as Google), the developers of Android. No; they aren’t to blame.
The fault is that of your phone manufacturer. If your phone hasn’t received an Android update that’s been made officially available, blame your phone’s manufacturer.
Picking A Smartphone
If Android software updates are important to you, pick a phone brand that has a reputation for making updates available in a timely manner. Your best bets are Nexus and Android One smartphones. Those get updates the earliest. Beyond those brands, good luck to you with whatever update schedule the various manufacturers put up. Depending on your choice, your smartphone may or may never get certain updates.
Ask around though. Some manufacturers have a better reputation than others when it comes to Android OS updates. All the best!
