The letv leEco le 1s is a very very good and impressive mobile of this price segment. It has 5.5 inch IPS LCD Capacitive touch display. It has got 32GB internal storage and 3GB RAM. But it has no external SD card slot for external storage. It also has a good quality 13 megapixel back camera and 5 megapixel front camera. This mobile has a Li-on 3000 mAh non removable battery and it runs on android v6.0 ( marshmallow) . It has octacore 2.2 GHz mediatek processor. This mobile has best features and processor according to its price range. Overall this mobile is very good, I recommend this mobile to those who want a powerfull 3GB RAM mobile in budget.
