Here I am typing this review with my LENOVO K6 NOTE 64gb internal.
This phon comes with two variants 32GB with 3GB RAM & 4GB RAM, 64GB with 4GB RAM.
Sound quality in phone is loud and nice but only one speaker given at base right side. 3.5mm JACK with DOLBY is awesome combination after setting up the sound settings.
FRONT CAMERA is average and good at low lightning but FOCUS is little bit slow, so when you take a selfie, you have to hold your phone tightly in hand for a perfect selfie,
BACK CAMERA is of 16 megapixel, having good efects on photos, low lighting capture is as average.not up to mark but best then other lenovo series.
Display is 5.5 with IPS LCD thats reflects good contrast but not like AMOLED. 1080 HD display is there.
Processor is good with combination of ram cortex A 47 WITH 4 GB , you can easily rUN heavy apps.
BATTERY BACKUP is too good full day BACKUP after hard use having 4000 maH. Charging is SLOW.
OVERALL good but your choice.
