To save an image in an email or in the browser, long press on the image and a menu will appear allowing you to save it.

For images inside text messages, you might have to press and hold on the message itself, rather than the image.

If you like to use vibration mode but you don’t want to disrupt a whole room due to the Lg K40 vibration intensity, you can adjust or reduce that accordingly. Just follow the steps below on your phone:

  1. From your home screen, swipe down to open the notifications menu.
  2. Tap on the Settings icon (usually a gear-shaped one at the top-right portion).
  3. Scroll to Device then tap “Sound” or “Sounds and notifications” or “Sound & Vibration.”
  4. Under Sound, tap “Vibrations” or “Vibration Intensity.”
  5. A bar will appear where you can slide left or right to adjust the intensity of your phone’s vibration. On some phones, users can select from either Light, Medium, or Strong.
  6. Tap “OK.” This will automatically save your preference.

This generally works for the Lg K40 and most Android phones.

For Huawei users, you may need to follow a slightly different method. If you use a Huawei unit, follow the instructions below instead:

  1. From the home screen, tap up to locate Settings.
  2. Then tap Settings → Strength
  3. Swipe up or down to adjust the vibration intensity. That’s from Strong, Soft, or None.
  4. Tap “OK.”
  5. You will be automatically reverted to the home screen. Don’t worry, your preferred vibration intensity is saved at this point.

To access the scientific calculator, simply open the calculator App and rotate the phone to landscape mode.

The calculator will automatically change to a scientific one.

To change keyboards (if you have additional keyboards installed), you can switch between them by pressing the small keyboard symbol in the top left of your screen. You will need to be in keyboard input mode (i.e. typing something) for this to work.

Alternately you can add and remove key board from settings also.

For that go to Settings – Languages and Input and then tap on Virtual Keyboard.

Now you can add and remove keyboards from this menu.

Note: you need to have more than one keyboard installed for this to work.

Depending on how your phone is set up, sometimes you will see lag when swiping between homescreens. There are a number of things you can try to fix this, as follows:

First, try restarting your phone. This will fix many problems.

If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc.

If you have Live wallpapers turned on, then try turning them off by going to Settings – Wallpaper, then changing to a different Wallpaper.

Go to Settings – System – Developer options – Window Animation Scale and Transition Animation Scale. Try changing these to 0.5x (or even 0). ? (you will need to unlock Developer options if you can’t find this. Use the search form on this site).

Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your homescreen shortcuts, but they are both great launchers.

Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key can leave it running in the background.?

If you want to clear your website browser history, cache or cookies on the Lg K40 because you don’t want other people to snoop around (or you just want to clean up your list), then that is actually very easy to do. Just follow these steps:

  1. First, open the browser you use and look for the Menu or “More” button/icon.
  2. Then go to History → Clear Browsing Data.
  3. At the top, you will see that you can choose to delete data from a week or several months ago. You may also choose to delete everything by tapping “All Time.”
  4. You will see a list of data that you can tap to clear. You can clear cache, cookies, passwords, browser history and more.
  5. Be aware that if you delete cookies you will have to login to your online accounts again.
  6. Then, select browser history, then tap “Clear Data.”

This method generally works if you use Chrome on your phone. If you have multiple devices that use your Google Chrome account, you might notice that your browser history, cache and cookies are also reflected on other devices. These may get deleted too if you delete them from your phone.

If you don’t want this to happen, you can turn off sync on your device. This means that the browser history, cache, cookies, and other private data will just be removed from your phone alone.

To turn off sync on your Chrome, just follow these steps:

  1. Make sure you have already logged in your Google Account on Chrome.
  2. On Chrome, click on your Profile / Account icon (located at the top right portion).
  3. Look for Sync is On → Turn Off
  4. After this, you can delete your browser history, cache, and cookies on your phone without removing it on your other devices.

For Samsung phone users who are using the default Samsung Internet browser, you can clear your browser history, cache and cookies in a similar way to that of Chrome users. Just follow these steps:

  1. Open the Samsung Internet browser.
  2. Tap on the Menu icon.
  3. Go to Settings → Privacy and Security
  4. Scroll down to Personal Data then tap “Delete Browsing Data.”
  5. A list will open up and you can tap to delete other data such as cache, cookies, passwords, location data, among others.
  6. Select “Browsing History” then tap “Delete.”

If you are using a different browser, the steps are almost the same. The key is to look for your browser’s settings and look for the “Privacy” or “Data” section.

How to clear the cache on your Lg K40

To clear your phone’s cache, the steps are similar with that of clearing your browser history. All you have to do is click on your browser and open its Menu. For Google Chrome users, just follow these steps:

  3. At the top, you will see that you can choose to delete data from a week or months ago. You may also choose to delete everything by tapping “All Time.”

If you don’t want to have to unlock your screen every time you take your device out of standby then go to Settings – Security & location.

Then select Screen lock type and select None.

If you want to remove an entire text message thread, go into Messages and look for the thread. Then long press on it and select Delete thread

When browsing on your phone you may notice images are quite blurry. This is because your telecom provider is compressing the images before they are downloaded on to your phone.

There is no way to prevent this, but if you have a WiFi connection nearby, then you can turn that on. This will mean that all browser downloads come through the WiFi connection, rather than the carrier, and your images will appear normally.?

This also depends on your service provider and data package.

With the recent versions of Android you can now take photos while recording video by simply pressing the screen.

This will save that particular frame to the gallery while continuing to record video.
