DAC: The DAC , so this phone has a headphone jack which we won't be able to granted much longer but the DAC behind this is not just a typical digital-to-analog converter so V20 is rocking a 32-bit hifi quad dac for significantly inproved headphone and speaker performance.
BUILD: The overall build quality and fit and finish of the V20 is lot better than the G5 from earlier this year.This is uni-body aluminum from top to bottom, and it actually really feels light. There is a pretty good use of space, fitting a 5.7 inch quad HD display and it is military grade shock resistant phone. It has a fingerprint reader on the back which is really quick. It has a 3200 mah removable battery and expandable storage as well.
SECONDARY DISPLAY: The secondary is sure LG thing that they did in the V10 and its good that they are keeping it in V20. So, it's a secondary display right on the top of the phone above the main display , this secondary screen is like a dock for permanent shortcuts for the things that might do often.
CAMERA: One of the best feature on the LG V20 is the dual camera, it is also very LG thing they have been doing it before .The V20 is rocking one 16 mp field of view camera and one 8 mp 135 degree super wide angle camera.
SOFTWARE: The top and no. 1 best feature of LG v20 is the software, this is the first phone running android 7.0 out of the box. So, this is new Android 7.0 with the LG UI on top of it. There is google's in app search feature which search your entire phone through all the apps installed, you get does which optimizes apps for standby.
It has all the high end thing like snapdragon 820, adreno 530, quick charge 3.0 ,USB type C, 64 Gb internals storage . so, this is a complete high-end package phone by LG
