Though Lenovo K3 Note is an nice phone spec. wise but its an killer phone by SAR values.
K3 note supports an 720p hd display. The display is very bright but the auto brightness sensor is not too good. Then video playback is supported upto 1080p smmothly.
The rear camera is of 13 megapixles and the front camera is of 5 megapixles. Camera is average in Lights but in low light the camera quality gets worst. Video recording is supported upto 1080p. And the video quality is not too great.
The phone is very fast because of Octa Core mediatek processor. Ram management is also fine. It has 16gb Of internal storage and the available user memory is about 10 gb.
Battery backup is not to great but alright at the price range. Very bad feature of this phone is the SAR rating and the SAR rating is too high and I will suggest you not to buy this phone because of the SAR rating.
