My boyfriend and I are US citizens traveling abroad to Spain- unfortunately the sams thing happened to his phone last night- squares would appear over icon box and passcode box, cancel box, etc. Siri even seemed to glitch and repeat the same words over and over activiating SOS. My boyfriend has been so sad the past 16+ hours- not for the phone, but the pictures and memories. After doing more research today, and stumbling upon your response- Bruno, I can’t thank you enough! It indeed was the Voice over feature that had accidentally been activated. After pressing home 3 times-sure enough voice over was checked. We unchecked it and his phone works again!
Thank you So So much!!! You are a memory saver!!
