LG Tips: How to select multiple images in Gallery app

Many users who just got a new LG smartphone are having a problem where they can't select multiple images in LG's Gallery app. Many will wonder how such a simple feature is missing in a high-end smartphone, but actually there is a different step to select multiple photos in Gallery on LG devices so that you can do multiple deletion at once instead of one by one. Before you go installing a third party app like Quickpic, here is how you can select multiple images in the Gallery app of LG G3, G4, G5:

Open (default) Gallery
Open the folder whose images you want to delete/copy/move
Tap on the delete icon on the top right screen
Now you can make select multiple pictures one by one or tap "select all" to delete everything

Similarly, if you want to copy or cut/move images to different folder in Gallery app, after step 2 above. Tap on the menu icon (three dots lined vertically) on the top right corner of the screen. Then tap "move" or "copy" and select the photos you want to move or copy.
