First I want to share my own personal experience with HTC Desire 830.I love this phone because its sound quality is very good.i can use this phone very easily.it is very fast & smooth.
I like that slimmest body.its color & design is very beautiful.
3 gb ram is enough for everything.camera quality is very good, rear camera comes with 13 MP and front camera comes with 4 MP.i love its 2800 mah battery, battery backup is very good. it has 5.5 inch HD display and 4 GB internal storage which is expandable up to 2 TB.
Price of these cell phone is 17999 rs.so its in our budget phone.i love it.This is the best phone for me.
