It is not uncommon for iPhones to encounter this problem as storage is one of the most important features for any modern device. Some users posted that their iPhone has 114 gb in the system storage.
Unfortunately the tips the Twitter account wanted to ‘share’ was agreed that it would happen only if he had 1000 retweets. Generally ‘other’ storage is uncategorized data on iPhones. According to a YouTuber, you can remove them by clearing the Safari cache or cache from other apps.
Sometimes Apple TV+ or Netflix downloads could be factored in there. Another easier but complicated solution is to just back up all of your contents and restore it back to the previous back up. That way all of the uncategorized data will be gone, however it will take a few hours to complete.
