Android as an operating system is constantly evolving. Google surprised many of its users when it rolled out the Android 5.0.1 Lollipop. But the update came with a memory leak. This hampered the performance of the devices in the longer run and Google started working on it right away. It released Android 5.1 Lollipop post that to take care of the issue but the update couldn't take care of the issue either.
Google's developers kept on working to address this issue and they have now been able to fix it. The solution should start seeding out to the users through the Android 5.1.1 Lollipop update but there is no word regarding the timeline of the update as of now. We believe the rollout shouldn't take long and you can expect the update in the coming few weeks.
What was the memory leak issue in Android 5.0.1?
The issue of memory leak struck the users of Nexus devices (primarily Nexus 5) after they upgraded to Android 5.0.1 Lollipop. What happened as a result of the issue was that many of Google's own apps like Google Plus used to crash or restart on their own. Many active apps started disappearing while being used. The amount of free RAM used to go down from 1.1-1.2GB to 700-800MB within hours of usage of the devices.
The RAM available used to decrease when new apps were opened but it never increased even after the apps were closed. This resulted in a poor overall experience and even the launcher acted up at times. With the issue getting fixed, the users of early builds of Android Lollipop are set to get back on track with the user experience they signed up for.
