Will this work on the A12 samsung phone

Works with the S21 Ultra. If the A12 has a USB-C connection there is a good chance it will work.

Will this work for my switch lite to connect to my tv using the hdmi?

No, the USB C to HDMI Adapter does not work with the Switch lite.

will this adapter work to hook up my phone to my roku tv. where we camp there is no wifi. i have a galaxy s9 thru verzion

I can not speak specificilly for the S9 but I have a S21 Ultra and it works like a charm - Highly Recommend. Also works great on my MacBook Pro. I often work at my place in WV and there isn't any viable wireless options, so I use my S21 (previously my S8) to stream content and as a hotspot. You could do the same thing with your Roku tv and stream through your phone or use the Roku functionality on the TV. That said, this adapter works extremely well for streaming from an app on your phone directly to your tv via HDMI. NOTE: (I had to do this) In order to get your S21 (and very likely the S9) to display on the tv in Full screen, there is a Display setting that needs to be updated on the phone. Under the Display option in Settings you need to enable the app in question under the 'Full Screen Apps' option. Enable the App in question to display the full screen on your tv and you are good to go (at least this is how the feature works on the S21).

Will it work with moto g stylus 5G (2022)

The key elements to this working are that the phone or tablet in question have a USB-C port (the moto g probably does) AND that is supports "DP Alt Mode". This last one is tricky because not all phones support this and not all phone specifications say whether they do or not. You're probably best off going to the Motorola support page and asking the question there.

works

Works with my android phone (with symmetrical shaped plug) but disappointed that I can't turn the display / screen off while using it on my tv like I can with Spotify and with anything on my laptop... but that's not the product's fault. My old computer couldn't update to use Netflix on it anymore. Works with my new mac computer. I like that it doesn't light up or flash at all! (But disappointed there's a red dot on corner of tv screen when using hdmi cord to hook up to computer -- but I'm pretty sure that's the computer's fault.) I really wanted to try an adapter that wasn't a cord at all with multiple types of outlets but felt iffy from reviews, stuff like 'it always has a light and is draining power even when computer isn't awake' -- so I went for this for now. I like that it's just a little cord to adapt it, without a box thing hanging off, seemed like that could cause problems or be more annoying.

Not compatible with fire tablet :(

Works great with my galaxy phone, but when i try to use it with my Fire tablet I get an error message that the tablet is sensing moisture. So I'm guessing it is not compatible with the tablet.
