Knock Code improves on LG's existing 'tap to unlock' KnockOn feature, making security more sophisticated by offering users up to over 80,0000 possible combinations - and making for fewer finger smudges on the screen.
The new security feature, which will also hit the F series and L series handsets, will start rolling out to older LG phones this April, with exact dates to be announced locally.
Worst. Joke. Ever.
