I have a samsung s3 ( i9305) and i have bought a few nfc tags and what i want to write on most of them is the function to unlock/lock the screen that also has a security pattern.
I used nfc task launcher to write them and everything went ok but sometimes the phone won't unlock. For example, i have one next to my door at home that when i "scan" the nfc it will unlock the phone and remove that protection and also turn on wifi. The problem is that sometimes it will only turn on wifi and it doesn't unlock but other times it does unlock but after a while it just returns to the lock pattern.
Anyone know how to make the phone really unlock when i scan the nfc tag? Im using the right app(nfc task launcher) or should i use something else also?
