Phone locked out - valid gmail password recovery not working
I have a Samsung Galaxy Ace. (Older phone with small internal memory)
My daughter locked out my phone and now I can't unlock it.
I have my gmail password which works with my online account but it doesn't work on my phone.
1) Does the email locked screen ever go back to the unlock code swipe? (after 24 hours?) I know my code.
2) When I logged into gmail it asked me to confirm my phone number which I did - resulting in a text message to my phone. Could this have caused an authentication problem?
3) Can I send an unlock instruction from my gmail account?
4) If I have to hard reset my phone what will I lose? I have no idea what I have backed up on gmail. maybe nothing. Is there a way to check from gmail?
