LG K40 is announced to be launched in Feb 2019 & will run on Android 8.1 Оreo. The Smartphone will be available only in one color black i.e. default & will also have a built-in fingerprint sensor as the primary security feature, along with the host of connectivity options in terms of 3G, 4G, Wifi Bluetooth capabilities. The phone will come with 32 GB of internal storage.

The Smartphone is coming a 2 GHz Octa-core processor. A 3GB of RAM will ensure the phone runs smoothly even the most memory intensive applications & show no signs of lag. 32 GB of internal storage will be open for expansion via a microSD card.

The K40 sports a 3000mAh battery, and given that it is not the highest running phone, the phone should be charged for at least a day. We don’t know for sure yet, and we’ll make sure of its speed during our upcoming full review.

Here you will not get any special battery facilities, such as fast charging or wireless charging, sadly. The back of the handset has a 16MP single shooter. It is not ready to blow you away with your photography skills, but it should be able to get you if you want to take weird shots to upload on social media.

We briefly tested the rear camera on the show floor at MWC 2019, which struggled to take a quick photo, but the device we were using was probably running early software. We will save our entire decision for our full review. It also has a front-facing 8MP camera, but we have not yet had a chance to try it out.

    you stated that Internal Memory was bad, what do you mean by that please?

    • Tom says:

      The Android system cannot work properly if the internal device storage is below 150 MB
      The phone needs more memory. If you move between tabs on chrome they will refresh thus losing anything that you were in the middle of on another tab. I have determined this to be a memory issue.
