I have used this mobile for around 2 years now and I have not faced any big issues. Its easy operable and no software or hardware problems. But one thing to be mentioned that sometimes I found heat in the back of the mobile, not often but rarely. I have suggested this mobile to one of my friend and he too have no big issues. worth to be bought so far and still going on well and good. There is no issues in installing some latest softwares like we are facing in some other mobiles.
