be careful what you download and install though.
I wouldn't trust just any QR-app on a phone, but if that's your last resort:
1. Install the app
2. Take the phone offline (Wifi and data)
3. Scan the QR-code
4. Recover your Bitcoins (and
Forkcoins)
5. Never use the same wallet again (but keep the backup anyway)
6. After moving your funds to safety, you can connect your phone to the world again.
