Lenovo has made tremendous starting by launching its Lenovo Vibe K4 note.
Head of Product and Marketing at Lenovo Smartphones in India, Anuj Sharma, clarified that the new K4 Note has been integrated with the Vibe series of smartphones.
Lenovo at the Delhi launch event on Tuesday also showed some statistics to show how popular the Lenovo K3 Note really is in the country. The handset was the third most searched phone in 2015, based on Google's release data for India , and the company had sold around 1.2 million units.

The first big difference between Lenovo Vibe K4 Note and its predecessor is in the design department: Where the K3 Note sported an uninspiring, blocky design and all-plastic build, the new handset features a curved back panel and metal on the sides. This is a design cue that Lenovo has picked recently with the integration of Motorola.

The phone is comfortable to hold with just one hand despite the large 5.5-inch screen size. The company has added a soft touch back which gives a good grip to the rear panel during regular usage. The front panel is mainly dominated by the display but the dual front speakers do add boldness to the handset. We tried the speakers on the Vibe K4 Note at the launch event and they did sound exciting and definitely different from regular speakers seen on mid-range handsets. The phone ships with metal frames on the sides that give the device a durable feel.

Lenovo Vibe K4 Note packs the Mediatek MT6753 chipset with 3GB RAM under the hood and comes with 16GB of built-in storage. You can expand the storage by up to 128GB via microSD cards as well as US OTG. The cameras of the smartphone have 13MP and 5MP resolution. Keeping the smartphone running is a 3,300mAh battery that supports quick charge.

The front houses three capacitive buttons for recent apps, home, and back options. The company at the launch said that the Vibe K4 Note will ship with a light version of the Vibe UI based on Android 5.1 Lollipop. The unit we used for limited period came with nearly stock Android UI with some tweaks made by Lenovo. The handset's home screen came with a Theme centre app that included various options to customise the theme on the handset.

In our limited time spent with the Lenovo Vibe K4 Note, we noticed that it handled all the multitasking and switching from one app to another pretty easily without any lag. The 13-megapixel rear camera on the Vibe K4 Note clicked images in normal indoor lighting to be vibrant with proper colours showing up. Low light shots also seemed above average. The front 5-megapixel camera also looked fine.

From the little time we spent with Lenovo Vibe K4 Note, it seemed like a good upgrade to the K3 Note smartphone. There was no lag while using the device, but with so few apps on it, there was not much to stress it.
