Lenovo a7000 which i have was upgraded to marsmallow with no cost. It was having 8 mp rear and 5 mp front camera. Which records smooth and shine pictures.
A healthy battery of 2900 mah gives it full power to run.
A bright flash light helps to take picture in dark condition. 2 gb ram help to run it smooth and freely. It is a 4g enable handset. The charger of lenovo a7000 is a superfirst one. It helps to charge the phone in 1hr and 24 minuite. So if you want to buy a smart phone between rs. 10000.00 then dont miss the chance to bye a lenovo a7000. It is the priceless smart phone i have ever seen.
