We previously featured a mod for the Samsung Galaxy S3 teaching folks how to unlock the device with NFC. This is quite a useful function if you’ve teamed your device up with an NFC-enabled case or with a Tasker setup. However, it was unfortunate that only one device could take advantage of this. Now thanks to XDA Senior Member peurocs4, a few more devices will be able to enjoy this function.
Peurocs4 has created a guide enabling users of devices with the ‘NFC on lockscreen’ mod such as the HTC One, Sony Xperia Z, and Samsung Galaxy S4 to unlock their devices with NFC. Additional requirements include a rooted device, the apps Secure Settings, Tasker and NFC Task Manager, and of course, an NFC tag that can be written over. Instructions are written with clear and easily understandable steps, and are aided with accompanying screenshots of the various settings and steps so you won’t miss a thing.
In addition to the already established end result, once the process is done, you’ll also be able to bypass the lock screen straight to your home screen with NFC, and lock the device again. If you’d like to see it done yourself, peurocs4 has attached a video demonstrating just exactly how it works.
