Rewind back to 2013 - 2014, a fingerprint enabled smartphone was really a huge luxury to acquire. yea i'm talking of the Samsung Galaxy S5 and the Apple iPhone 5s which were one of the first phones to have a fingerpront unlock.

But we all know that fingerprint scanners have always been vulnerable to hackers who are willing to go the extra mile to bypass them. Over the years, we’ve seen everything from people using Gummy Bears, Play-Doh and more.

Today we will show you how to unlock a fingerprint phone with nothing but a mere sellotape.

Here are the things needed for this trick.

Sellotape
Your Fingerprint enabled smartphone
The first step is to roll out a small piece of tape from the roll of sellotape, and paste it on the finger which is already registered on your smartphone

Then you use a second finger to press the sellotape tight on your finger.
Remove it gently and paste it on the fingerprint reader on your smartphone.

iola! device is unlocked!
Please you should know that this doesn't mean you should be walking up and down with sellotape in your pocket looking for who to duplicate their fingerprints.
