Q: Does it work with Android?
A: No, this model is for iPhone and iPad only. For Android phones, choose the Accsoon SeeMo 4K for Android.
-
Q: Does it work with older iPhones with a Lightning port?
A: Yes. A USB-C to Lightning cable is included for monitoring, recording, streaming and charging as usual, but the SD card reader only works with USB-C iPhone / iPad models.
-
Q: Can it record video to an SD card?
A: No. The SD card slot is only for transferring files to and from an iPhone / iPad. Video recorded via SeeMo is saved to the iPhone / iPad Camera Roll.
-
Q: Will it drain my iPhone battery quickly?
