Since I am in Jewellery business need a good mobile which can last for a long term. After sales service also should be good. Internal Storage is good/big enough as there may be always 3-5 lakhs jewellery pics on my phone stored always, processor is fast and camera quality is good. Not too costly and too cheap. Any ideas or suggestions let me know experts please. My budget would not exceed more then 15-25k. I want to keep it to 20k but should not exceed more then 25k. But you can suggest me like 3 different models good, better and best and then i can choose on any 1 of them.
