If you are an Android fan and want a secure smartphone then BlackBerry DTEK50 is the phone you should go for. Priced at Rs 21, 999 the smartphone come with all the high end security features designed to keep you data safe and secure. The smartphone has a 5.2-inch display and is also designed very nicely. It has a textured back panel for firm grip. The handset is powered by a Qualcomm Snapdragon 617 processor paired with 3GB of RAM and 16GB internal storage which can be expanded up to 256GB via microSD card. There is a 13MP rear camera with dual LED flash and an 8MP front camera for selfies. I have used the smartphone myself and is definitely a good buy within the price range of Rs 22, 000.
