The version of Android that comes with the device is useful for emergencies. The list of apps you can install is very limited, and the video quality when using these apps is low. It also staggers a little bit (or maybe has like a 20 framerate). So, I recommend using the HDMI port. I tested it with a Chromecast TV 4k and another with HD. Videos play much smoother with them. But it staggers with scenes with high movement. That staggering is usually imperceptible. I managed to highlight it with a clip of a panoramic capture taken by a drone. I managed to reduce the staggering by switching to 1080p at 50Hz instead of 60Hz. The brightness is fine. You can even use it during the day. It supports only SDR, of course. The speaker works ok. Enough to listen to the news, but not for enjoying movies. You can connect a Bluetooth speaker, and the problem is solved. I couldn't find any section to configure the audio, so I imagine it supports only Stereo. The photo with Youtube was taken using Chromecast with GoogleTV (the HD version). It doesn't support HDMI-CEC, so you will have to use the projector's remote control to turn it on, off, and change the volume. The USB ports available are powerful enough to power a Chromecast v3 (those that do not have a remote control). These ports are powered only when the projector is on.

For anyone who doesn't want to read all this, the projector is good, would recommend, but it has areas for improvement. Image quality: In dark places, it's a 10, in slightly light places an 8, and in very light places a 5. Sound Quality: The sound is good, but if you increase the volume too much, it starts to distort. System: Android 9.0 is "ok" as you can feel it's old, but it handles YouTube and Netflix quietly. Bluetooth: Not sure if it's just the one I bought, but the Bluetooth is bad, I have an LG Home Theater, and it connects but seems like the connection is weak, lowers the sound, and even cuts out. Focus: If you place the projector at the corner of a wall to project to the middle, the focus is either in the middle of the screen or one of the corners. You have to keep the projector aligned with the middle of the wall or screen for good focus. Video Game: I have an Xbox Series S, and I had no problem playing games, runs 1080p - 60fps.

Great image transmission in the dark, large screen, the image is clearly visible on beige textured wallpapers. Works great directly through HDMI with a laptop or YouTube from a phone via Wi-Fi. Possibly flash drive too, but I don't need that feature. In the video, the distance is about 10 feet, positioned almost exactly (off by about an inch). If you raise it higher, the left edge starts to blur. Dust gathers quickly on the lens; if you watch movies with many dark scenes, they are visible ?. The built-in speakers are quite ok for a room of about 215 square feet; planned on a speaker, but it was unnecessary for me. Easy to set up, needs AAA batteries for the remote (not included). Overall, I think it's an excellent purchase and recommend it. It was delivered on time and in perfect condition.

The projector connects to Wi-Fi (2.4) right away but doesn't seem to see the 5G network for some reason. The picture is quite nice, colors are good (red is actually red, green is actually green). The picture is clear if you place it exactly parallel to the projection surface. There are no spots, the image is clear across the entire screen area, no lights or blackout. The built-in speaker surprised me; the sound quality is good and quite loud without wheezing or slurping. For a 193 sq ft room, it's more than enough. The fan noise is not loud, you stop noticing it after 2 minutes.

Everything is as described, clearly visible on the walls in light is weak or off. When adjusting the angle, if the projector is below or above the projection area, the clarity of the top or bottom is lost. There is no horizontal adjustment. I took the version without Android, opened the flash drive, shows pictures, didn't start movies. The sound of the built-in speaker is good, loud enough, the noise of the fans is not significant.
