I purchased Lumia 435 in last year, It is good to design, light weight, smart looking, and fully features mobile. In this most affective that has 1GB ram to run smoothly. Camera is average as 2MP rear and front is 1.3MP not so good but effective in less price. It runs on windows phone 8.1 and also upgradeable to windows 10 mobile build. Battery backup is average. Microsoft’s good idea to launched it, It is great to whose want to have mobile in less price in fully features. They give come back come lots of fully features product in less price, and give fully facility also. Thanks to Microsoft Lumia
