Lenovo K4 Note: Specs, Price And Review

The Chinese handset maker, Lenovo has already carved a niche for itself in Indian handset market with A series smartphones like A7000 and A6000. After having settled down nicely in the market, Lenovo is now innovating and coming up with cutting edge smartphones. The handset maker is now launching new devices with new-edge technologies and re-defined design. Lenovo has now launched a successor to its much revered K3 note in India and the new device is nothing like the existing one. Here is our review and breakup of all things Lenovo K4 Note for you as the handset is on its way to repeat the massive success of its predecessor.

Lenovo K4 Note: Specs, Price And Review

Design and build quality

In terms of design, Lenovo K4 Note is an entirely different device from its successor and comes with a new design form. The new handset does feel slightly light and less premium than Lenovo K3 Note, however, it does feel premium owing to the metallic sides and matte back. Another detour from the standard design of Lenovo is the metallic strip on the rear panel housing the fast fingerprint scanner and camera module. The fingerprint scanner is quite fast and also allows the user to set tasks on gestures like tap the scanner of touch and hole. Coming back to the design of the handset, the smartphone seems to have been built for multimedia lovers

The front panel of Lenovo K4 Note is dominated by a large 5.5-inch display, which seems to be a little bit on a dimmer side as compared to the K3 Note. Prior to the launch of the new handset, Lenovo has been promoting the device as the one with a Killer Display. However, the end product on offer tends to disappoint as it comes with the exact same display that features on its predecessor. The display panel on the smartphone is a full HD IPS unit with a resolution of 1920 x 1080 pixels and pixel density of 401 ppi. The display of the smartphone is also protected by a layer of Corning Gorilla Glass 3 layer for durability.

Hardware and specifications

The Lenovo K4 Note has been equipped with a Mediatek MT6753 64-bit Octa-core processor that flaunts a clock speed of 1.3 GHz. The processing prowess of the handset was visible in the system animations and juggling around apps during our brief stint with the handset. We also played the Asphalt 8 on the handset and the game was able to run in the high visual mode.

The presence of 3 GB of RAM further eliminates any kind of lag or stutter that might result from multitasking. In our experience, we found scrolling in menu, app switching transitions and animations to be on the smoother side. Moreover, the Theatermax technology and Dolby Atmos audio enhancements totally enhanced the multimedia experience on the handset. It comes with 16GB of internal space where only 9 GB is available. You can expand memory storage up to 128GB using MicroSD card.


Speaking hardware, the rear panel of Lenovo K4 Note flaunts a 13 megapixels camera with dual tone LED flash and Phase Detection Auto Focus. The brand has changed the user interface of the camera slightly from its earlier devices and it now comes with a minimalistic layout. Popular controls on the interface have been well placed by the brand for an easy access and it is also easy now to switch between camera and video mode, with just a swipe.

Equipped with the Phase Detection Auto Focus, the camera on K4 Note is able to lock focus pretty fast and that is a huge plus. The camera on the rear panel captures decent images in low light conditions and good in normal lighting. However, it is a drawback that the camera takes few seconds to process the image after capturing and user needs to keep their hands steady. The front 5 Megapixels snapper also performs decently with clear selfies without any over contrasting or overexposure issue. All in all, the camera performance of Lenovo Vibe K4 Note is a delight and will appeal to photography lovers.

Operating System

Lenovo K4 Note comes with the Android 5.1 Lollipop operating system pre-installed, which boasts of goodies like Material design and enhanced performance features. In our brief stint with the smartphone, we noticed that the device comes with a revamped Vibe UI featuring an app drawer. The Vibe UI comes with lots of additional features over and above the stock Android UI like pulling a C from edge to trigger micro screen mode, double tap to wake and our personal favourite, scheduled turn on and off. The phone may receive android 6.0 Marshmallow update soon but till then enjoy android 5.1 Lollipop.


For connectivity, the handset maker has opted for the dual SIM structure for K4 Note as usual that will appeal to most Indian buyers. This handset has been designed to offer super-fast Internet connectivity since it has both 4G LTE and 3G bandwidth integrated in it. The highlight of the handset happens to be the presence of NFC, which happens to be the future of smartphone connectivity and will also bode well with Google Pay. Besides these, K4 Note comes with standard set of connectivity options like Wi-Fi, Wi-Fi Direct, Bluetooth, microUSB and GPS.


Coming to the battery powering the handset, Lenovo has improved upon the battery over Lenovo K3 Note in the new smartphone. The new smartphone comes with a powerful 3300 mAh battery that is an upgrade over the one in K3 Note. A 3300 mAh battery pack is enough to power your phone more than a day under normal usage. The phone supports the fast charging feature.


Taking its configuration under consideration, Lenovo K4 Note impresses in some departments and disappoints in other. However, with integrated VR feature, bundled VR headset and fingerprint scanner, the brand has managed to raise the bar for all other devices in this price range. Considering, Lenovo K4 Note price, one thing is for sure that this smartphone is definitely the one to reckon with a set of specifications that belong to high end. You can either buy the smartphone alone for only 11,999 INR and may opt for the phone with VR bundle at just 12,499 INR.

WhatsApp Is Now Free For Lifetime But You Can Still Pay For A Friend

It official WhatsApp is now completely free for lifetime and will not charge the annual $1 fee. WhatsApp service is free for the first year after that you have to pay a minimum fee of $1 per year to stay connected. In India WhatsApp is always free. Users who installed it the first time are getting their service time period automatically renewed to another year. In India WhatsApp never charged any fee. It is also free in most under-developing countries. Now it will be free in the USA also. Today WhatsApp is free because almost 1 billion people rely on it for their day to day communication and everybody doesn't have credit or debit cards, so it may make someone sad that after one year their service will be stopped. So, making it completely free solved the problem and now nobody has to worry about the service expiration.

whatsapp free for lifetime

This is not it, WhatsApp founder Mr. Jan Koum has new plans to connect the businesses. You can even call your bank to get the details of the transaction. Or you can order goods from local businesses by just using WhatsApp. This may be the new business model through WhatsApp will generate revenue.

It is even faster than normal mobile messaging service. Also, the communication between android smartphones will be completely encrypted making the app the largest communication app to chat privately.

However, the app is completely free now you can still pay for a friend. You can either pay for a friend for 1 year, 3 years or 5 years. The fee is the same. This feature will soon be removed too in the next app update.

USB 3.0 Drive Working As USB 2.0 In Windows 7/8/10: How To Fix

USB 2.0 storage devices are around us since the year 2000. 8 years later USB 2.0 was superseded by USB 3.0 which is said to be 10 times faster than it. USB 3.0 storage devices are now even available for smartphones. The read-write speed in the v2.0 is very slow as compared to the v3.0. So if your desktop computer or laptop has a USB 3.0 port then you can transfer data to and fro at very high speeds. This will save your time.

But most people face a common problem when they do not get the desired transfer speed even after using a super speed USB 3.0 storage device and a compatible port (it is mainly blue in color) in Windows 7/8/10. This problem arises due to the missing drivers and incorrect BIOS settings. If you are experiencing this problem then you should follow this tutorial to fix it.

Downloads Required

USB 3.0 Drive Working As USB 2.0 In Windows 7/8/10: How To Fix

  • Download and install the driver given above. After installation reboot your PC.
  • When you reboot to desktop a pop up will appear. Click 'Run'.
  • This is the driver popup it will appear everytime you start your computer.
  • If you don't want to see this popup on every startup then uncheck 'Always ask before opening this file' when the popup appears.
  • The popup will not appear again but the driver will work.
  • Now connect the USB 3.0 drive and format it to 'FAT32' partition with 64 KB 'Allocation units size'.
  • Now reboot your computer and go to BIOS settings. 
  • Refer to your laptop manufacturer's website for information on getting into the BIOS.

Now you can test your USB 3.0 flash drive (pen drive). The reading speed will be close to 100 MBps and writing speed will be around maximum 16 MBps. With reference to USB 3.0, reading speed means when we copy data from flash drive to hard disk and writing means when we copy data from hard disk to flash drive. Only 3.7 GB data can be transferred from the flash drive to HDD in just 40 seconds.

The v2.0 flash drives can only reach a maximum reading speed of 20 MBps and writing speeds up to 10 MBps.

How To Install Remix OS On Your MAC Or Windows Computer

Remix OS is the modified version of android which is based on the android-x86 OS. The remix OS is designed to run on Intel and AMD processors. This is a Linux based operating system and is currently not that powerful to fully use the computer's hardware resources. JIDE technology has developed this operating system so that you can run android on your Windows PC or MAC computer without even wiping your C:\ drive because the OS runs on a bootable USB device and you can anytime go back to your original operating system.

Currently, the Remix OS is in alpha testing, so most apps are not working on it. You should wait for the stable version. Till then if you want to experience android on your computer (PC) then we are here to teach you.


  • A USB drive at least 8 GB in size.
  • A laptop or desktop computer having a USB 3.0 port.
  • Remix OS for PC ISO - Download

How To Install Remix OS On Your MAC Or Windows Computer

  • Download the ISO and extract it on your desktop.
  • Plug in your USB drive and format it to 'FAT32' partition.
  • Now open the Remix OS USB Tool. Click browse to grab the ISO file.

  • Now click OK to create the bootable USB. It will take some time.
  • After it is finished it will ask you to reboot your PC.
  • After rebooting, get into the BIOS settings and change the boot option from hard drive to USB.
  • Then save the BIOS settings and exit.
  • The Remix OS will start running from the USB drive.

Note: Please note that changing the boot option in BIOS is different in different computers. So, you should have to check yourself the boot options. Basically, the first boot option is the HDD, then the optical drive. You have to change this order and choose the 'USB' as the primary boot option.

How To Install Apps In Remix OS

Currently adding a Google account is not working in Remix OS. But you can manually download android apps and install on it. There is an inbuilt browser in it. Tap the start button in below left corner to access the browser. Make sure to setup Wi-Fi in 'Settings'.

Remix OS Lets You Run Android On Almost Every PC And MAC

We have seen many ways to run android OS on our desktop computers and MacBooks. The most popular way of running android on X86 computers is the android SDK. Then came BlueStacks app player and finally I have seen android-windows. But all of these methods are not enough to completely experience android on desktop computers because they run very slowly. JIDE technology has devised a way to run android on PC/MAC in a desktop-style operating system. JIDE has developed Remix OS which is a modified version of android that runs via a USB 3.0 drive on your PC or MAC. With Remix OS, you are actually running android in a desktop-style OS. It also has a start menu and recycle bin. So, everything looks like a Windows OS.

JIDE has also developed Remix Mini, a device having an HDMI output which is capable of running android OS on any screen having an HDMI input. You can use this device with your TV or monitor having an HDMI input. This mini android PC fits into your pocket and only costs $70 in the USA.

If you are using the Remix OS on your PC/MAC then you can install the ISO in a USB 3.0 drive. USB 3.0 drive is required because it is 10x faster than version 2.0. To run this OS fast and smoothly your laptop or desktop computers should have a USB 3.0 port.

How To Install Remix OS On A PC/MAC

Actually, we are not installing it on our computers. We are installing the ISO file on a USB drive and will boot the OS from it. It will not delete your existing Windows OS/MAC computers. Follow the steps below to install.

  • Download Remix OS for PC/MAC - Download Link.
  • Please note that Remix OS is currently in alpha version so you may find bugs in it.
  • Download and unzip the file on the desktop.
  • Use the 'Remix OS USB Tool' to burn the ISO to USB 3.0 drive.
  • After burning the ISO turn off your PC and go to BIOS settings.
  • In BIOS settings change the boot option and select the USB drive.
  • Wait for few seconds for the operating system to load.
  • You can either select 'Guest Mode' or 'Resident Mode' before using the software.

That's it for now. We will do the brief of Remix OS later and will tell you everything about it. If you liked the article then please share it.
