The Lenovo gallery is as simple as they come. It has three view modes - Album (that is folders), Location and Time. You can change the size of the thumbs in the Settings menu. Additionally, you get basic editing tools - crop, rotate, plus some color effects and borders.
Thanks to the Cast screen option in the notification area you can easily throw your photos up on a large (Cast-compatible) screen. The slideshow option is also a tap away.
The other option is SHAREit, but that mostly works between devices that have the same app preinstalled (so, other Lenovos).
The video app is capable of three ways of ordering your videos - Intelligent, Date or Name. We found no explanation of just how the Intelligent mode works, but you can always fall back on the search feature if all else fails.
The player employs gestures - swipe sideways to scrub through the video, vertically to change the brightness. You can snap screenshots from videos and switch to a pop-up window.
The Lenovo Vibe K4 makes big promises about sound quality (thanks to the Wolfson audio codec), so we were a little disappointed to find only Google Play Music. It's a fine app, but somehow we expected something special.
Anyway, you will want to get into the settings menu where the Dolby Atmos screen holds the equalizer and other settings. You can change different modes (Movie, Music, Game, Voice, Custom), each getting its own 5-band equalizer setting. Additionally, you have automatic equalizers (Open, Rich, Focused) and things like surround virtualizer, dialogue enhancer and volume leveler.
The FM radio is a nice touch. Sure, you can stream with Play Music, but FM is free. The Radio app can record radio broadcasts, but lacks RDS (the feature that displays the station name and other info).
The Lenovo Vibe K4 Note showed perfect clarity in the first part of our audio quality test. When attached to an active external amplifier, the smartphone produced great scores top to bottom, but unfortunately its loudness was rather disappointing.
Damage from plugging in our standard headphones was rather modest - a moderate stereo crosstalk increase was all we saw. Once again however the volume fell seriously short of the average mark so we can’t award full points here. Still a pretty solid showing for the price range.
Here go the results so you can do your comparisons.
