Use NFC with Screen Off or in Lock Screen on Galaxy Nexus
While it hasn’t hit the mainstream yet, Near Field Communication is on the rise. With a number of flagship Android devices shipping with a NFC chip installed, users have been finding more and more uses for NFC. Is the experience perfect? Far from it, but improvements are being made all the time to make NFC a bigger part of the Android experience. There are many tools out there to help NFC users make full use of NFC, and now there’s at least one more way to make the experience even better.
One fault with the current implementation is that it usually requires the screen to be on and an application to be running for NFC to work properly. While some may not mind this, there are users out there who would rather be able to use their NFC more quickly and would prefer to be able to use it with the screen off. This is a problem that XDA Recognized Developer Geniusdog254 is looking to solve on the Samsung Galaxy Nexus.
The mod, which is flashed in recovery, allows users to use NFC with the screen off and on the device’s lock screen. As Geniusdog254 explains:
This is a modified Nfc.apk, which is the system NFC service that runs at boot. It allows you to scan NFC tags either with the screen totally off, or with the screen on but still at the lockscreen. You get to choose which one you want to flash. Just download one of the zips below, and flash it via recovery (tested with ClockworkMod). To restore to stock, just pick the stock version.
This makes the NFC experience easier and more efficient for frequent NFC users and it’s pretty easy to implement. That’s a win-win situation.
