LG Optimus L3 Quick Memo

It has all features of a typical Android smartphone. But, what makes it unique is its inbuilt hidden feature called QuickMemo. It allows you to take memos or notes quickly when you are in a hurry or when you need to jot down some information while you are on phone with someone. Not just that, you can also take screenshots, edit them and write on them.


Quick Memo

To open the QuickMemo menu, L3 users should hold up and down volume keys simultaneously. Then, they are presented with a blank screen where they can write anything they wish.

As you can see, this feature can be quite handy to the users of LG Optimus L3. But, if you possess a different Android phone, don’t worry, there are plenty of apps in Play Store which do the same job as that of QuickMemo, and provide you with even better features.

Alternatives : Evernote, GNotes.

    Thank you for this information regarding the Quick Memo. I would like to know if it is possible to control the sim switch key?

    This button keeps changing over the sims when attempting to press the return button.

    Thanks You

      Omar, it is possible to change the button function. It takes modification of system files and is complex. But, if u change the function of SIM switch button, how would u switch SIMs? There is no other screen option for that.
