By now, we are all familiar with just how good the Galaxy S20 series of smartphones is; the phones are amazing and loaded with brilliant specs that make them a wonder to use. However, much like newly released phones, these do have some issues that the company is currently working on.

At launch, the users reported that the Galaxy S20 Ultra's main camera has issues with autofocusing. Thankfully, that was just a software issue and Samsung did work on resolving that right away through an update. We also heard the news about the 45W fast charging that is found on the S20 Ultra not being as fast and stopping after reaching 30% of battery, after which it shifted to 25W, presumably to stop the phone from heating up. These issues were isolated at first but then more and more users started reporting it around the world. While they appear to be software issues rather than hardware ones, Samsung has not issued a comment on those.
