Having a password, PIN, or combination lock on your device can be quite an inconvenience every time you want to unlock your phone, especially when you have one for the sake of guarding against snooping eyes. If this is the actual case for any of you Samsung Galaxy S3 users out there, you may be pleased to know that you can bypass this problem while maintaining the security with the help of NFC tags.
XDA Forum Member Monteillard has come up with a sneaky way of making this possible on your GS3 for rooted users with Tasker, WidgetLocker, and NFC Re-tag, all of which can be found on the Play store. Users must flash a specific mod that’s available for download, setup WidgetLocker with the ‘unlock’ function, create four profiles with specific settings laid by Monteillard, and then add your NFC tag with NFC Re-tag with a couple of required settings to get things started.
The advantage of this mod is that you’ll now be able to unlock your phone with NFC tags and bypass the security screen, while maintaining the security that you have with your password, PIN, or combination lock when others get their hands on your GS3. There’s no restrictions on which NFC tag will work, as generally anything with NFC, be it textiles, NFC stickers, cards, or tags, will be compatible. Owners of other devices may be able to get this working, as one such user with a Sony Xperia S has done so successfully. However, the fact that you must flash a GS3-specific mod through recovery may mean otherwise for most.
