I am using this Nokia Asha 500 and it is best for calling & listening songs but the apps which are in this device is useless because when you open some of the app it start hanging and the operating system become slow which really feels bad for any nokia users. The battery backup of this phone is really good its having 1200mAh battery and it gives the backup of 2 to 3 days, sound is loud and clear, camera is in average if you click some picture in day time its gives clean and nice shoot. Nokia has added many apps to this device but whatsapp very useful for day-today life. Whatsapp is of no use for this device because whenever I click on whatsapp it says that "Do you want to download this app" and when I click on yes its says error, whatsapp doesn’t work on this phone. Nokia asha 500 is having small screen and the device is fine but again I’ll say that this phone is the master of hanging and my openion is not to buy this phone becz the price is little high, and if you add some more money you can buy easily a good smartphone
