I have been using this product from the last 6 months. I bought this in amazon. Initially I had no problem but later on what I felt is this product is not worthy because of its quality. The battery started draining fast after 4 months. And RAM management is not good. That 2GB RAM is not able to handle HD games. Coming to ROM that is our choice. Cam is horrible dont expect much from it. The touch sensitivity and display is not having any problem up to now. It doesn't support LTE. I even got network problems some times after an update it was resolved. This is my 6 months experience. I am not that much satisfied with this product.
