One of the worst thing after my phone crashed, was losing thousands of photos. Only around 400 were personal and the ones I really cared. Somehow, although I always use the back up option of Google Photos, they are gone. Never happened before. I'm talking about more than a decade photos. I suspect something went wrong with MIUI, the skin/OS of Xiaomi phones. Lately I would see some photos or files hidden. So, copied everything to the microSD card. When I got the new phone , somehow stumbled upon this article saying that if you insert a microSD card on new Xiaomi models, the phone will format it and delete everything. So, thinking about getting one of those bundles that you can connect to a desktop computer and back up them there first. I used to backup my files on multiple websites but at some point I stopped because it was pointless, they shut down sooner or later. I also lost all of my bookmarks, around 7.000 but at least found some of them on Raindrop app.
