I was planning to buy an Android smartphone to replace my old Smartfren Andromax U which does not support 3G connection. I think I am going to choose a smartphone made by Lenovo, Lenovo S850 series. Lenovo S850 is an Android phone with some interesting features and hardware on board. For example it has MediaTek MT6582 Quad-core 1,3GHz Cortex-A7 GPU Mali 400MP2 as the main processing unit. Also it comes with 13 MP rear camera and 5 MP front camera which are sufficient for me to take hi res pictures.

Lenovo S850 is equipped with 13 MP, 4128 x 3096 pixels, autofocus, LED flashFeatures Geo-tagging, touch focus, face detection, HDR as the main rear camera. You can easily take stunning pictures with this camera. 1 GB RAM, non upgradable is good enough when combined with a quad core processor. Switching from one app to another will be smoother.
