smartphone projector

Listings commonly show native resolutions of 1920×1080 (Full HD) and 1280×720 (HD). Several descriptions also note support for 4K content in addition to the projector's native resolution.

Many listings mention electric or automatic focus and describe keystone correction (for example ±15°). Several also include automatic keystone correction, auto-leveling, or auto-focus to help align the image.

Most listings include built-in speakers. Several also list Bluetooth streaming or two-way Bluetooth (so the unit can act as a speaker or pair with external Bluetooth audio). A few descriptions mention a 3.5mm audio jack for wired output.

Listed lamp or bulb-life values include 10,000 hours, 20,000 hours, and 30,000 hours; one listing states a bulb life as "2 Years," and some listings do not indicate bulb life.

Several listings state that copyrighted or protected streaming content often cannot be mirrored directly from a phone. They note that playing that content typically requires an external streaming device or a connected computer or TV stick via HDMI.
