I bought this device because of the design of the smartphone and because of the best supportability of jio sim.
As talking about features,
Lyf Water 7 smartphone was launched in June 2016. The phone comes with a 5.50-inch touchscreen display with a resolution of 1080 pixels by 1920 pixels at a PPI of 400 pixels per inch.
The Lyf Water 7 is powered by 1.5GHz octa-core Qualcomm Snapdragon 615 processor and it comes with 2GB of RAM. The phone packs 16GB of internal storage that can be expanded up to 128GB via a microSD card. As far as the cameras are concerned, the Lyf Water 7 packs a 13-megapixel primary camera on the rear and a 5-megapixel front shooter for selfies.
The Lyf Water 7 runs Android 5.1 and is powered by a 3000mAh removable battery. It measures 155.30 x 77.20 x 8.50(height x width x thickness) and weighs 160.00 grams.
The Lyf Water 7 is a dual SIM(GSM and GSM) smartphone that accepts two Nano-SIM. Connectivity options include Wi-Fi, GPS, Bluetooth, FM, 3G, 4G(with support for Band 40 used by some LTE networks in India). Sensors on the phone include Proximity sensor, Ambient light sensor, Accelerometer, and Gyroscope.
But after using it for a month I have found that its battery backup is not that much good than other smartphones in this range but the camera quality is awesome and is very impressing.
All over its a nice phone!
