Google’s newly launched Android 5.0 operating system (OS) is under fire, with several users experiencing problems and issues.

Some users are reporting issues in connecting to their workplace Wi-Fi network, mainly through routers from Cisco.

Two new issues have been raised with one involving a wrecked manual account sync button in settings, and the other concerning frequent restarts of apps in the background, Android Police reports.

Users claim that background apps suddenly close, while the launcher keeps redrawing every time users return to it. Apps are displayed as ‘restarting’ in the running apps section within the Settings menu.

Upon updating to the latest Android version, some users observed a ‘Cancel sync’ option instead of ‘Sync now’ within the Accounts tab in Settings.

Users have also reported that the OS eliminated ‘silent mode’ from their devices.

A bug was also reported by some Nexus 5 and Nexus 4 users, who had an issue with the new Flashlight toggle within Quick settings tag.
