My Honor 9 lite just updated to Android 9, after the phone restarted it asked for SD card password, which I never set. I tried to put the card into PC, but it won't get recognized at all. I have seen found post from other people in other forums having the exact same issue with Honor phone as well, but all the replies are people reporting that they have the same issue as well :/
I have a document I really need to recover in that card, I could swear that I backed it up, but being the dumbass that I am I must have forgot to do that.
