  • Good Entry level phone. Value for money
    Magin George (May 1, 2015) on Flipkart
    Good entry level phone. UI is pretty simple with no noticeable lag. Battery llfe seems to be reasonable with a day backup with moderate use. What it lacks is the notification led.Sound is reasonably loud and camera quality is good in good to moderate lighting conditions. Overall a good ENTRY LEVEL phone and for 4499 (Including 10% credit/debit card offer) its a steal.

  • Exellent and Tremendous Phone
    Harsha Simha Raj (May 1, 2015) on Flipkart
    The phone was simply Awesome. If you want a android at cheap and best, go for it. You can close your eyes and buy this. But the missing one is the ear phones. The ear phone not usual as to the other phones, it's port is different. The normal nokia or samsung ear phones not working good,there was some distubance in it. So it is better to buy the new sony or jbl head phones to this phone. Over all phone's working is very good exept the audio jack. This is the good phone from Huawei. Thanks to Flipkart For Fast Delivery. But the Flipkart is cunning becuase, at the relese time of the phone it cost's 5000, But after one week the product is offered with 10-20% Discount. I have bought 2 phones, one of price 5000 and another of 4750(5% offer). After i puschased this both it is now offered with 10% with credit cards and 10% with luanch offer. I have disappointed with this. So don't Buy phones at the time luanching. Wait for week and then buy.
