You'll need to get the screen replaced. Check around local independent repair shops and get quotes. You can also fix it yourself if you're really comfortable with it
This sounds like it got liquid inside the machine and if you see any signs of corrosion, I highly recommend you leave it to a professional. Every major component like RAM, CPU, and memory chips are not only soldered onto this machine, they're also programmed. If these components are damaged in some way and cause a short circuit, not only do you kiss your machine goodbye, you can loss your data with it. Check out Rossmann Repair in NYC. They do accept mail in repair and come highly recommended. The owner, Louis, has a youtube channel you can check out and is a big right to repair advocate. I hope you can get your machine fixed yourself though! I wish you luck!
As far as I know, there aren't any parts distributors selling screens without polarizers, which I would assume you're looking to make a "privacy" screen that requires special glasses to view? If that's the case you'll have to disassemble, remove the polarizer, and reassemble it yourself or find someone willing to do so.

You can order the part from Mobile Sentrix. Just be aware that it’s just the part, no tools. https://www.mobilesentrix.com/lcd-assembly-with-frame-for-samsung-galaxy-a02s-a025m-2020-us-version-refurbished-all-colors
I would start by taking a look at the bevel gear. Luckily ifixit has a guide to access it. Looks pretty simple to me. Just follow the steps carefully and keep track of the parts. If you see chipped teeth or metal chunks/shavings, ya might need to replace the gears and refill the grease. I’m not sure what kind of grease they use but I’m sure you can find out online.
The microphone issues may be caused by a hardware issue. The iPhone 7 and 7 + were notorious for two common issues, Baseband PMIC (power management integrated circuit) and Audio IC failure. Although they’re not really failures. When the phone flexes from being dropped or over normal use, these integrated circuit chips would pop off the board resulting in either the microphones and speakers not working or getting a “No Service” message with a warning triangle next to the service bar status. As far as the camera issues go that does sound like it may be caused by iOS. Does that happen with both cameras or just one of them?
Could be a defective display or if you didn’t disconnect the battery you could’ve blown the backlight circuit. If the old screen was still functional, hook that one back up to see if it works. You don’t need to worry about transferring the front camera and home button. Just connect the old display and power it on.
Can the TouchID keyboard be purchased separately if the original seems to fail? I’m looking on Apple’s website and it doesn’t appear to be available, at least for the time being.
I would like to add that you’ll need a special tool to read and copy the serial number to the new Taptic Engine so that it will provide proper feedback.
