Personally, I recommend options that are as close to OEM or brand manufacturer as possible where available. iFixit sells an aftermarket adhesive kit for the rear cover [product|IF355-006|here|new_window=true] as well as options for the [product|IF355-008|battery|new_window=true] -and screen if you want it. These are aftermarket, but they may serve the purpose with similar efficacy if they leverage the same method of adhesion. The downside is that you may not manage to get the equivalent of restoring the IP68 rating for an S8, which implies a complete protection dust contamination and waterproofing up to 1.5 meters under fresh water for 30 minutes. Assuming that you're not looking to let your phone take a dip, these kinds of specialized films and strips are a perfect fit. You may be able to find cheaper options as well as guarantees/return options through other online retailers, so do your research.
