I just want to know why the pic get blurred when this device having 48mp camera... U can see... Please give me solution
Even if you pick 48mp, you can't expect DSLR quality when zooming in a lot. It also looks like it's not super bright and in these cases you will have a longer shutter time with 48mp than 12mp giving less focus/sharpness.
I always recommend to take a 12mp shot first and then another 48mp shot if you have the time. Sometimes in good conditions 48mp can give a really impressive result but for most cases, 12mp is the best option.
