please suggest me the phone with following description.
Touchscree-3.2-3.5 inch
Android- v4.0
Camera-5 MP
Processor- 1 GHz
HTC Desire C or if you are not Brand Biased, then take a look at the Karbonn A18 and Micromax A90 or A100. You may also consider the SE Live With Walkman but I heard the Android 4.0 update was buggy.
There may be more options if you are fine with GingerBread.
Desire C is a good phone but has got a poor processor.
Have a look at Sony Live With Walkman.
Why don’t you extend your budget upto 14K?
Sony Xperia U (with dual core & excellent benchmark scores) is available at 13.5 K (with dealer warranty).
Sony Xperia Neo L & Sony Exricsson Ray are also available with few online dealers for 13.5 range.
I am not familiar how these dealer warranty works, but some are offering warranty through a third party network called ServePro.
If your budget is already upto 13K, then please extend it few more & go for Xperia U. With the dual core processor & ICS, you will not regret for the next 2 or 3 years. With manufacturer warranty, it might be close to 15K, please check with your local stores.
