The phone is packed into a plasticky, rather than glass or aluminium shell. This is perhaps the factor that contributes most to the U12 life not feeling or looking like a flagship level or top end phone, one that every device in the INR 30000 range should feel like.
If you do not want a notch, and want something different than all the Samsungs and Apples out there, then the U12 life can be a reasonable option. We would be hard pressed to think of any other reasons why you would want to purchase this phone, though.
Important features of the device include a dual rear camera setup with 16 MP and 5 MP shooters, 6 inch screen, 64 GB of storage, and the Snapdragon 636 chipset. The phone, as stated before, does not lend any high end feel to the user, and one can instantly tell the difference between the U12 life, and for instance, the OnePlus 5.
The design at the back does a decent job of salvaging the look and feel of the phone, but we just cannot ignore the fact that the glass feels like plastic.
So, should you buy this phone? Only if you want a brand which has been long lost in the depths of the smartphone market, and you want no notch. Even if the latter is true, you could be looking at better options in a similar price range or lower.
