Ok so we all know nokia is good brand in terms of sevice and trust .coming to the mobile this phone is quite below average because it does not have more pr better feature than other phones.
Other phones at same price give better feature.
First of all this phone is not easy to use at all because interface is too bad. the design and body of nokia lumia 520 is attractive and eye-catching but it does not have front camera.it comes only with back camera which is of decent quality.the durability of phone is good .it has very low ram and insufficient storage to store apps.
After using it for 1-2 months this phone become really slow and personally I faced lot of hanging and lagging issue.this phone is great for office workers as it has many features like ms word , excel etc but again any andorid phone can give feature like this also the touch response is not good.this mobile is not worth money or we can say not value for money. So overall this phone is below average and I would not recommend it to anyone!
