Spot on with the recovery mode instructions. I've noticed that while the wipe itself is quick, that initial splash screen on reboot is where people usually panic because it hangs there for a while. It's totally normal though, basically just the OS setting itself back up from scratch. From a technical standpoint, the S10 uses UFS storage so it's usually pretty efficient, but if your storage was nearly 100 percent full, the file system might take an extra minute to sort itself out during the wipe phase. Quick question tho, are you doing this to solve a specific performance issue or are you getting ready to pass the phone on to someone else? Also, did you already make sure to remove your Google account in settings first? If you dont, you might trigger the Factory Reset Protection lock which is a whole other headache.

• Honestly, I think relying purely on a recovery wipe is a bit risky if you haven't backed up everything first. I had a bad experience years ago when my phone hung during a wipe, so now I prefer using Samsung Smart Switch on a PC to do a full image backup before I touch the recovery menu. It gives me peace of mind. Also, if you're worried about data longevity, keep in mind that the flash storage in these older phones can start to degrade. I always suggest grabbing a Samsung EVO Select 512GB microSDXC UHS-I to keep your media off the internal memory if you're planning on keeping the phone for a while. It works well and I've had no complaints with mine for the price, usually around $35-40. Just make sure you do a clean sync before you start the process, and you'll be golden. Don't stress too much about the boot time, just let it sit there and finish the initial setup without interruption.

A factory reset on an S10 usually takes a few minutes, but larger data amounts can increase this. If it takes excessively long, force restart your phone. Yes, holding power and volume up simultaneously enters recovery, where you can select "Wipe data/factory reset". Remember this erases everything! If the boot loop persists after the reset, check recent forum discussions as Odin may not be a solution.
