Do MagSafe chargers work with Samsung and Google phones?

Technically yes, but with major caveats. Discussion in r/GalaxyS25 flagged that many Qi2-marketed pads only deliver 5–7.5W to Samsung phones because Samsung uses its own proprietary fast-charging profile. Pixel users in r/pixel_phones also reported alignment problems unless the phone has a magnetic case. For full speed on Android, look for chargers explicitly listing Samsung or Pixel fast-charge support.
