There are some photos which are very personal you want to keep them only to yourself. If someone see them by chance, it becomes very awkward and embarrassing. To avoid that, you can simply install the Vaulty app and feel safe while handing over your phone to anyone:
I will recommend you Redmi Note 5 Pro. Sporting a 5.99-inch IPS LCD display, it comes with a metal case body and has a thin-bezel design. Under the hood, there is a Qualcomm Snapdragon 636 SoC (8 x 1.8GHz) and it is coupled with a 4GB RAM. With 12 MP + 5 MP Dual Primary Cameras you can capture images of 4,000 x 3,000 pixels. Along with the front camera, an LED flash makes sure that you can make video calls at night. It consists of a 4,000mAh Li-Polymer battery which supports quick charging. It is equipped with a wide range of strong features.
