Adding to the long list, two new bugs have been reported - one about the broken manual account sync button in settings, and another about frequent restart of apps in the background.
After updating to Android 5.0 Lollipop, some users are claiming that the Accounts tab in Settings is just offering a 'Cancel sync' option instead of a 'Sync now' option, which is usually the case. In a regular use scenario, Android users are required to manually select some accounts to sync on an Android-powered device if un-synced. The bug is listed on the Android Issue Tracker as "Manual sync is broken on Android Lollipop (final version)".
Android Police speculates that this is a bug after further investigating, and writes, "The reason we strongly suspect this is a bug is because if you uncheck and check an item in your sync list and then quickly go to the 3-dot menu, you'll see 'Sync now' is back - briefly."
Interestingly, hitting the 'Sync now' button doesn't do the said process and rather shows the 'Cancel sync' option.
Another bug reported by some users is one that is causing apps to restart in the background leading to performance issues. One of the notable issues caused by the bug is that it closes the app with 'persistent notifications' sometimes. Android Police believes that it might be a case of "memory management issues or memory leaks."
"It could even just be a bug that's closing apps too aggressively, even when there's plenty of RAM," it speculates.
Several users say the only way to fix the issue, which has been reported in Android Issue Tracker as "Memory Leak on Lollipop crashing Apps", is by restarting the device. One user writes, "I have to keep rebooting my nexus 5, I like android lollipop but, it uses RAM too much."
Another user claims that he noticed the bug on the Nexus 9 tablet while the Nexus 4 is not showing signs of any such bug. He writes, "I'm seeing this on my Nexus 9, but not on Nexus 4: apps are killed and restart after switching to another app for a short time."
The broken manual account sync button has been reported to Google twice by users; though there has been no reply from the company, as pointed out by Android Police.
Likewise, Google has not replied to the background apps crashing bug either.
Some of the other Android 5.0 Lollipop bugs recently reported by users include Wi-Fi bug; app switcher bug; another bug caused the very useful 'silent mode' from phones, and a flashlight bug was also reported to be affecting some Nexus 5 and Nexus 4 users.
