Slightly off topic .. I will just like to post my process of buying .. it has never let me down since touchscreen app driven phones came out and can work from a budget as low as 5k to as high as 50k (deciding between a Xperia Z5 and
iPhone 6 at budget of 45,000 is as hard as deciding between a
Lenovo K3 and Mi4i)
1 ) Decide what is max price possible (keeping in mind your final choice maybe 20% over max price. Let us say my budget is 6K, I must be prepared to pay about 7.2k)
2 ) Decide what is the use - is it gaming, calling, primary internet device, camera, overall performance.
3 ) Decide OS. Some (like me) are happy with KK 4.4. Some will want L 5.1 out of the box. Some will want best and fastest upgrade to new OS (if this be a criteria then
Redmi will take more than a year, if ever, to upgrade. Just an example -- not meant to upset Redmi fans)
3 ) Based on above, decide specs in detail. If camera is not your primary purpose but calling and good looks, do not waste time trying to think if 10 MP phone will be better buy than 5 MP or reject a phone just because front camera is 1 MP. Focus on the need. If gaming is your main concern focus on benchmarks, gyro and not looks. Your final spec sheet should be very specific of what you want and do not want and while specific your spec sheet should be open to reasonable alteration.
4 ) Decide brand
5 ) Decide model
6 ) Purchase
7 ) Lastly forget about service centers. You only need service centers to buy OEM battery. Unless you can afford to throw it away, do not buy should be the motto for buying cell phones. Your cell phone budget should always be what you can throw away and not blink.
If it seems like "gyaan" awfully sorry folks. But this flow chart has made me the go-to guy for buying cell phones for about 25 people in last 4 years (not to speak of my own eight or nine sub 9k phones from 2009 all of which have been tremendous value for money purchases and sold well on second hand market.)
