Nokia lumia 520 is a very dificult to use and understaning like other phones. Its sound are normal. Nokia lumia phones desing are not good. Camera have low quality and not flash light. Frant camera is too bad. I think this phone is expensive price with the feature are inculed in this phone. Its have an over weight.
The phone is hard to use and problem during using. Not good app are avialble on windows app store. Less of collection. Problem on buletooth during used and hard to used. Improve the features and to make easy for use you spend a more time. So its time waste phone. I don't recomment any one. Thanks.
