Are your eyes sharp enough to solve this brain teaser driving people crazy on Facebook?
An image of a floral carpet, uploaded by Jeya May Cruz from Pasig, the Philippines, has been shared nearly 16,000 times and reached 120,000 reactions.
Why? Because the photograph contains a camouflaged mobile phone that is devilishly hard to spot.
The image is the latest in a string of viral puzzles confounding the internet. If you are struggling, the phone has a floral pattern which does not quite match the carpet.
Still confused? The device is just beside the right side table leg at the top of the photo.
