I may buy one of the following.
Xperia L ------ Everything good but display is 4.3" I wanted minimum 4.5"
Xperia M ------ (Waiting to be released in India, hope it gets released soon otherwise dropped from my shortlist. Though display is 4" I will still consider if released soon if price is lower)
Lenovo S890 ------ Good specifications but looks not very attractive.
Lenovo P770 ------ Good specifications, good battery but does not have white color, looks not very attractive.
Lenovo A706 ------ Good specfications but looks not very attractive.
I do not want to take risk of Indian brand and regret later. Indian brand may not be wise choice around 15K.
Thank you all for your suggestions.
