The Android SDK Manager has a welcome new visitor in Android 5.1.1. This could quite possibly be one of the most eagerly awaited Android builds of some time. Unfortunately, the underlying demand for this update has nothing to do with aesthetics or performance. It has to do with a memory leak that has afflicted some Android users since the Android 5.0.1 update.
Google has acknowledged that the leak existed, but also posted that the necessary repairs had been made. Google did not have everything ready to go for Android 5.1, which is why the Android 5.1.1 update is so important to many Android users. After all, who wants to see the amount of available RAM on their handset drop sharply for no apparent reason? We might also see the addition of a VPN (Virtual Private Network) which would allow users to tap into a Wi-Fi network to communicate over a Google owned VPN. This would give more privacy to some Android users.
Just recently the stock Android Nexus devices received Factory Images for Android 5.1. The first-generation Motorola Moto G Google Play edition just became the first Google Play edition handset to receive Android 5.1.
Putting this all together, it means we could see the Android 5.1.1 Factory Images released soon for Nexus models as the cycle repeats itself.
