Using NFC On Galaxy S III With Phone Screen Locked


The Samsung Galaxy S3 GT-I9300 has an embedded NFC chip that allows you to share files to another NFC-capable device. Aside from sharing files, you can also pay your bills and launch certain phone functions and apps instantly through NFC tags. But, for you to use this feature, you will need to unlock your phone’s screen first to activate NFC. This can be an inconvenience if you’re in a hurry and you don’t have the time to unlock your phone.
XDA Developers member mayhemer offers a convenient solution by creating a hack/mod that allows you activate NFC without unlocking your phone’s screen. The hack/mod has two flavors: one that allows you to enable NFC even if the screen is locked (provided that the screen is on), and the other that activates NFC even if the phone is asleep or on standby (even if the screen is off).
The mod/hack can be useful when you have NFC tags in your car, on office desks, and in the bedroom and you don’t want to have to unlock our phone to activate NFC. You can also instantly share files even if the phone’s screen is off or locked.
But, you will need to be careful, though. Flashing this mod could potentially open the gates of unrestricted data transfer, including malicious hacks and viruses reaching your phone. Make sure not to leave your phone unattended; or, put it somewhere where no one can easily access your phone. NFC chips need to be close in order to communicate.
This guide shows you how to use NFC on the Galaxy S3 I9300 even if phone screen is locked.
