Unknown Icon on iPad Lock Screen I don’t know what that white glob like thing right over left upper corner, I think it’s kinda bug , it just doesn’t look good can any body tell me what is that and how can I take it out
I believe it's because you have no SIM card in your iPad. It seems to appear in place of the cellular icon. It looks to possibly be a bug. You could try restoring it, that could fix the issue.
