I bought Samsung Galaxy M21 for my brother from Kozhikode district in kerala.I bought the reven black varient. It has 6GB ram and 128 GB intenal storage.The back of the phone is a plastic body. But it display is well designed. It also comes with a 15V fast charger. I thing the highlight of this model is its 6000 mAh battery.It has 188g weight and 8.9mm thickness. The back of the phone has a 48MP primary camera, an 8MP wide angle camera 5MP depth sense camera. It also has a 20MP selfie camera. So you can take good photos and vedios with good clarity. I think the 3.5mm audio jack sets this model apart from others. The rate of this model is 15, 999.But I bought it for Rs15, 000.The Samsung Galaxy M21 is mid range model for samsung lovers.
