      Hi BostonS,
      Thanks for sharing your experience, and we're sorry the charging performance didn’t meet your expectations. While MagSafe-style alignment can work with some Android models like your 25 Ultra, it’s important to note that Samsung devices don’t officially support MagSafe, which can lead to slower or inconsistent charging.
      Also, if you're using a thick phone case, it may prevent proper contact between the charger and your device, causing slow charging or even failure to detect the phone. For best results, we recommend using a thin or MagSafe-compatible case to ensure stable wireless charging.
