I bought samsung galaxy note 2 in 2012 for 37000 rupees when it was a flagship phone and it was my first flagship phone. I am using since then and never had a complaint about it till now. About a year ago, the phone seemed to me as an outdated one due to heavy competition and the updates stopped. I was stuck on kitkat. Then I entered into the world of custom roms and everything changed.
I learnt everything from xda developers , rooted my phone, downloaded recovery and installed custom lollipop rom. Currently I am on marshmallow. U won’t beleive me but currently note 2 is one of the best developer phones in the world. It means it is very much liked by developers due to its reliability and so it has the highest number of roms and mods available. Its not a phone to buy today because of its features but due to its reliability.
