I have purchased Nokia Lumia 535 three months back for my brother. As it is windows phone with attractive features. It has 1gb ram, 8gb internal memory.It has a lightening performance as well as all the features in a budget phone.
Camera Quality and pictures are good as well as battery prolong for a day. So far it is running great, people were talking about hanging problems in this phone. Till date I have not noticed any such issue.
A very big thank you to Nokia for launching a budget phone with awesome features. I strongly recommend it.
