  • I am using the A11 star, a phone not listed here but available on flipcart, needed a cheap smartphoen for whatssapp and other uses. the phone is great. real smooth touch and ips screen is great, at 4.3 its just big enough , the phone is shaped like an xperia phone but sadly no covers for it , but it does look great, and at 4500 its great value for money , does hang a bit but all in all if you need a cheap smartphone for a few months , this is the phoen to get . regards .

  • is this possible to Video call on Sim network not any other apps.

  • Hey!guys,im using this phone since a month.touch is very smooth.call quality is good.rear camera is ok in daylight but at night it is worst.the flash is above average. 2.plays 1080p videos smoothly.i have tested it. 3.the build quality is awesome. 4.performance wise the phone doesn't lag at all.even with multitasking mali 400mp gpu works here. 5.if u want multitasking menu double click the home button. 6.gaming:the gaming is also very good.i have tested frontline commando,subway surfers,temple run 2,dr.driving,asphalt 8,dead trigger 2,riptide gp2,asphalt 7 heat,modern combat 4,nova 3,nfs most wanted,gt racing 2,drag racing. All the games works fine note:i have played asphalt 8,nova 3 in medium settings. Over all at a price point of rs.4099 it is a very good deal.if u r budget is 4000 don't go for any other phones believe me it worth every rupee of it.And finally it is available only on flipkart.com.thanx.
