Lenovo a6000 — Issues after lollipop update

Address:

Pathanamthitta, Kerala, 691530

I updated my A6000 with Lollipop update... But this update has so many issues... I request you to share these issues with your technical team so that they can fix these in next update... (1)In this update there is no settings for Profile(General, Silent, Meeting Mode). How can you forget that. It is very important in day to day life. Plzz fix this. (2) The Themes(UI) are very poor. Themes in KitKat was better and after update they are gone. Plzz give them back. (3) The device is not running smoothly...(4) Old version of File browser. If you can't update then, at least, plzz don't downgrade. (5) No settings for pixel adjustment in camera app. And many more ... But these are very important... So, plzz share it with you tech team... And fix these issue at the earliest. Hoping for a quick resolution of these issues... Thanks.
