Such incidents have not happened in my neighborhood or in my friend circle and in my case either. But I’ve heard a lot through this forum. When a person buy Bitcoin from a medium where he will store it is very important to remember the password there is in his wallet because if the password is not there, you will lose money completely. He should have been careful here. And since he lost the phone, if his wallet’s backup doesn’t have it, he’ll lose money. It's normal. I sometimes forget such passwords, so I use notepad and also use geography notepad so that such situations don’t have to be faced.
