Best android phone in India.

Hi there, I am using an old Galaxy 3 today, planning to buy a latest Android mobile phone.

Which one do you suggest?

If you want best than don't go for Samsung Galaxy Series Devices.
Samsung stops giving software updates after 1 - 1.5 years to their phones.
Their 2 Years support period is an invalid claim. All other phones are just Android Based phones not Android Phones.
Just wait till Android Nation Store launches and buy a Nexus Smartphone from Google. Nexus lineup are actual Android Phones and when an Android OS update is released, It first supports Nexus lineup. Believe me you will be more than happy for buying almost any latest Nexus phone.

Hello Raj, Welcome to Collegelib!
about Samsung support, this is a bad news! My phone is of more than 2 years and started shoeing some problems like restarting automatically some times, say once is a week. I will have a look at Nexus series, thanks for the suggestions. If I can visit an Android Nation, I would have a variety of phones to select from.

If you are getting automatic restart problem than do this:
Go to settings > Privacy > Factory Data Reset.
Done.

I think factory reset will clear all the data stored in the phone, isn't it? How to take a back up now?
