Nokia asha 503 is the worst model I have ever used in my life .Soon the touch pad system became unresponsive.The quality of the photos are not good.Use of internet and other apps will make it further worst.It will hang so many times and become slow.It is one of the most unreliable and untrustworthy model.i recommend everyone not to go for it.It is very costly also as compared to other mobile phones.I purchased in 7399 which is too high.nowadays mobile phones have become very cheap and pocket friendly.please go for other models.
