Yes. The phone clamp has a range of 58mm to 103mm (2.28" to 4.06"). Both of these phones, even in a standard case, fall well within this range. The only limitation is with very bulky folio-style or battery cases, which may need to be removed.

A standard 1.25" eyepiece has an outer diameter that fits perfectly within the NexGO's 25.4mm to 44.45mm clamp range. Simply place the clamp over the top of the eyepiece and tighten the orange knob until it's secure. Then use the X-Y knobs to align your phone's camera with the eyepiece lens.

No, it's one of the easiest adapters to use in the dark. The large orange clamp knob is easy to find by feel, and the X-Y adjustment knobs allow you to center the bright image of the Moon or a planet on your screen in seconds without needing perfect initial placement.

The NexGO includes a smartphone booster specifically for this situation. Place the booster on the phone platform before clamping your phone in. This raises the phone, providing the extra height needed for smaller devices (typically 5" tall or less) to align properly with the eyepiece.

Swapping phones is extremely fast. The phone clamp is spring-loaded, so you can remove one phone and insert another in just a few seconds. You will likely only need minor adjustments with the X-Y knobs to re-center the new phone's camera, making it ideal for sharing views in a group setting.

Yes. You can switch your image orientation by simply loosening the eyepiece clamp, rotating your phone to the desired orientation, and re-tightening. A quick readjustment of the X-Y knobs will re-center the image for your shot.
