Karbonn A21 is a hell of a smartphone powered by a mighty Dual-core snapdragon processor which clocks at 1.2 GHz. The phone is priced at INR 10,499 and is available for around INR 500-1000 less than the MRP. The snapdragon processor ensures lagless performance of the device and is able to handle the 480x800 resolution of the device. The only drawback is the 400 MB ram that's available to the end user. The tagline for the device says: "Style meets Technolgy" and the device indeed looks stylish and gives a premium feeling. Just if this device had packed 1 GB ram, it would have been a killer combo of specs and price.



Other specs of this device include:
5 MP back camera
1.3 MP front camera
4.5 Inch capacitive screen
External Memory: Upto 32 GB
Internal Memory: 4 GB
Sales Package: Handset, Charger, Battery, warranty card, headset
RAM is being reported to be 1 GB by many websites, I would want anyone having the device to confirm that.
1800 mAH battery
5 HRs. talktime, 200 HRs. standby
Dual SIM, Dual standby

Rooting Guide (thanks jgsolo27):
Available here.

The RAM and camera is the only let down of this device. Check iGyaan's youtube channel for hands-on video review.

Other than that the pros are, its resolution is qHD 540x960 (First budget phone to get this, rest other phones are WVGA 480x800), dual-core CPU, greater build quality.

Exclamation
Guys I'm really seeking answer to this question. Is anyone able to play HD videos on this mobile? I've tried the MX player with arm v7 codecs and the mobo player but all HD videos above and including 1080x540 resolution are lagging heavily.

I'll be grateful for an answer since the max resolution which its playing without any lag is 960x540 which is screen resolution.

Is there any way to play HD videos on this?
