I have tried the lostmode function on my Galaxy S Advance and it seems it unlocks the device which is absolutely not desired in this situation. Scenario:
- My phone initially locked by a pattern. It is important, if it is locked by PIN unlocking does not happened.
- While lostmode function activates choose 'call' on the device.
- Interrupt the call before it established, and start to save the contact.
- Now the phone is completely unlocked, however pressing home button will activate the PIN unlock screen.
I managed to reproduce it twice.
