The phone is excellent and does not cause any major problem but there are little cons of the phone.
1. During charging the phone heats up and also during long duration of calling.
2. The back camera is not that great but it gives decent pictures.
3. After 2-3 months of usage you will find that phone is lagging a bit during multitasking or while running heavy files.
I think for now the better option would be letv le2. The rest in the phone is fine and is not about to worry at all. I hope this will be help you better.
