Am upgraded to lolipop.but I feel now its a bad decision .because now my phone is getting slow.and phone consumes more power.in ideal condition all the core is working.before I upgrading in ideal condition only one core is working.available ram is 200 mb of 899 at this moment.temperature is much higher than the previous one.
I bought this mobile 2 weeks ago.after upgrading this version it perfomanse is very poor compared to previous version.in the previous android version am very happy with the battery power.it will consume only 5-6 percent in ideal condition for nearly 7 hrs.now I think I need to carry my charger along with me. it take some times to load icons after closing some application by showing loading launcher.and icon view is better in the prrevious one.third party application icon view is not good in this version
