I just went to restart my pphone and this weird warning in korean came up. I cant do anything with the phone now.  the store is closed… due to staff shortages.  it gives 3 options… but my volum button is sticking and I was just about to make a claim against my insurance… its only a few months old.


what can i do to try and unstick it. Its the only phone number the school has for emergencies for my kids. 


any suggestions would be greatly appreciated … can do anything..
