Well,
My brother had this phone few months back and that was a very irritating period for him as the mobile had nothing to do with it.
It was not open source as it was windows so very limited features.
The cameras were ordinary.
The battery backup had nothing It used to drain faster than waterfalls
It used to hang a lot, the internal memory was very limited.
The phone would heat up while using.
Finally one fine day it stopped working, the motherboard got damaged I don' t know how.
My brother used it for hardlay 9 months.
