Microsoft lumia 430 is not a user friendly phone to use. The data sharing applications are less in the store.in the app store the number of available applications are less. Data sharing applications like wifi sharing is not working properly.
The only possibility is transfer through bluetooth and it takes too much time. I think the microsoft should add more applications to the store like playstore for android.this phone has 8 GB internal memory but most part of the memory is assigned as system memory.
