To day I will tell about my bad experience of samsung Rex 70S3802 . It is a very bad phone. I brought this phone 5 years ago.with 4000 rupee. This phone is powered by Java. Its sound quality is very poor.it have a 3 inches screen.most bad think that you can not download any apps or games or very important app like WhatsApp and Facebook are not supported on this mobile. it’s onli one camera with 2 mega pixel so camera quality is very bad . This phone’s battery is not good after 1 hours charging this phone battery backup is only 30 minutes.it is only 10 mb phone mamori . it’s very hanging. So I suggest that it is not a good phone.it is fully wast of money
