Budget: 15-20K Usage: In preferential order Music Texting/Calls Gaming Photography Brand Preference: Samsung and rest reputed ones. No Micromax, Lava or Xolo please. Prior experiences bad with them. Only special criteria is that phone should be able to handle bit extreme operation environment coupled with rough usage.My last to last phone was a Samsung model of Galaxy series, almost 3 years old, pretty rough usage and still has no major structural integrity issues even after suffering numerous falls from varied height over the years. Please suggest accordingly.
