YouTuber says Samsung may have a problem with swelling phone batteries
 

Samsung may not have left its battery troubles completely in the past. YouTuber Mrwhosetheboss (aka Arun Rupesh Maini) and others have noticed that batteries in Samsung phones are swelling up at a disproportionately high rate. While this most often affects older devices where ballooning batteries are more likely, some of them are only a couple of years old — the 2020-era Galaxy Z Fold 2, for instance. It's usually obvious (the phone back pops loose), but it can be subtle enough that you may not realize your battery is in a dangerous state.
