An example of such case was recently shared with our team:

“Ugh, my phone died at the worst moment! I was at the park, taking a walk, and saw this crazy sight – a majestic deer chilling with a cheeky squirrel, all bathed in this perfect afternoon sun. I totally pictured it going viral! Phone fame, here I come! But of course, my phone had other plans. It buzzed with this annoying message: ‘Storage Almost Full!’

By the time I frantically deleted a bunch of random stuff, like old memes and cat videos (not that important!), it was too late. The moment was gone, the animals scurried off, and I was left with the sad truth – my phone hoarding, especially all those giant attachments, totally messed things up.”
