As yureka is a cynogen based cellphone, it can be rooted as warrenty dont void. There are lots of bugs in it. Has features in it, but have to face forced stop problems. Apps get closed so easily , after getting started. The most facing problem is heating issue. It heats up so much, that you cant even hold it, and makes us so uncomfortable to hold.
After sometime of use it also gets hanged up and boot up automatically. I seriously used the phone as my primary phone, so had to faced huge complications. If you are a heavy user, you can get satisfied for sometime, but after it can hang up after sometime or even can get switch off automatically. But a budget phone, and a good phone for a normal user.
