Blackberry z3 is a haf hearted attempt from blackberry to make its presesnce felt in the market again, the phone was launched in may,2014 by the company and the sales figure are not enough to save blackberry from accumulating losses and its falling to negligible market share.
the phone has a 540 x 960 pixels capacitive touchscreen with 220ppi and the screen does not comes with any kind of protection like corning gorilla glass. why would someone give 15000 for a such low resolution when you can get full HD phones for this price.
It has internal memory of 8gb and ram of 1.5 gb and it supports micro sd card upto 32gb.
it has a 5mp autofocus back camera with led flash and a 1.2mp front camera with 720p video recording capability.
it has BlackBerry 10.2.1 OS installed on the phone. the processor is Qualcomm MSM8230 Snapdragon 400 which is a dual core processor clocked at 1.2 Ghz, it also has a adreno 305 Gpu.
Seeing the overall specification sheet one can easily say that the phone is not worthy to buy at all, it has a low resolution screen, average camera, and lack of apps in the blackberry market.
Dont buy this phone at all infact go for Xiaomi mi3 which is far more superior at this price bracket.
