Lollipop still need fixing of bugs

Lollipop is the best android that is release till now.But it still needs the fixation of some serious bugs.
In on of my posts,I told you on the bugs in Nexus phones.Now,some users are facing a bug that is causing the connectivity issues on wifi.The bug so far doesn't seem to be affecting non-Nexus devices.Not to forget that some users are also having the issue on the battery.
I also came across a person who had a problem in accessing gmail.He also pointed at the bugs that he faced in hangout,Google Play Music including the Google Newsstand.
Unless the bugs are cleared,you guys have to try your best to overcome the bugs.
