Page last built: 2026-09-14

Models in this series may share some parts, but compatibility must be verified for each part individually — this page groups them for browsing only. Where an exact per-part verification exists, the model below links to it.

S8, S8+, S8 Pro Ultra, S8 MaxV Ultra, S8 Max Ultra

Do not assume these fit: despite similar names, S4, S4 Max, S5, S5 Max, S6, S6 Pure, S6 MaxV, S7, S7+, S7 MaxV, S7 MaxV Plus use different parts and are NOT covered by this page.
