Recent Samsung Galaxy S8 update breaks fast charging for some owners

Unsurprisingly, affected users have voiced their concerns over the internet. There are multiple appeals for help on Twitter as well as a number of threads on the Samsung community forums:

Normal charging appears to be working, but we can understand if people are frustrated with their phone taking up to 6 hours to recharge. Fortunately, this may not be a widespread issue, but we certainly hope that Sammie will address the problem quickly. The Korean tech giant hasn't acknowledged the bug yet, but we'll make sure to keep you updated on any developments.
