You can use the app Rotation Control. A combination of the settings in that you can force it to go to portrait (a little counter-intuitive but use the Guard Mode with Auto Rotation mode in the app and it'll work).

I use the Macally tablet holder. There is also a shorter necked version.
Vent clips will rip off your vents.
The RAM suction cup phone mount, which is a perfectly designed phone mount, just isn't strong enough to hold the big girl in rough roads.
Macally tablet holder is large enough to hold it securely. Never dropped it once even in very very rough off road trails.

You can customise the duration of the vibration or pattern it makes using apps like Light Flow, I've set it up on mine because I find I miss notifications, so I can set the key apps I use to send reminder notifications to me. You can set up your own patterns you want to use so if you want more vibration set it to be on for longer, less set the duration for a shorter burst.
I've set up using Keyboard Designer from my Key2. The app has plenty of flexibility to setting it up. It has a useful word selection option that you can enable and customise as to how many options it displays.
I've cheated and set up to use a mini on screen keyboard which I've set up on mine to offer punctuation, emoji and numbers with a mix of press, press and hold, and swipe up. Got most special characters covered using this method. I got rid of the suggestions as I felt it just took up to much space on the already limited screen.
If you just want raw texting, I've been using Textra for a few years now and find it to be really good at doing just that and it's been the way forward to me since I had a Nexus 4 replacing the default SMS app with each new phone.

Like you I don't have a real interest in all these 'better' features, I just want a simple send a message and it gets where it needs to be. I dont want read receipts or other junk.
I used a vent holder and a windshield mount. Hated the latter due to it falling off all the time. I eventually bought a Syncwire Magnetic mount. I love it. Only downside to it is not being able to wirelessly charge my phone now because of the metal plate on the back of the phone. Maybe when I get my silicone case from Unihertz I can put it on that so I can drop my phone on a charging pad every couple of nights.

Button Mapper may be able to help - https://play.google.com/store/apps/details?id=flar2.homebutton&hl=en_GB
It's worked for remapping buttons on every phone I've had with Android so far so I can't see why this would be any different.

The problem is that the key combination gives the same key code as the app switch button (APP_SWITCH 187 is what the w,d,k and the recent key both show up as). So, you can turn it off, but then your app switch button also does not work.
There is a slight workaround where you can reconfigure it from being a single tap to a double tap. It won't prevent w, d, k from still performing the same action if double tapped. It also takes some time to get used to having to double tap the button.
But if the w, d, k keys keep getting hit together (although I have no clue why this combination would ever come up during usage) then the double tap workaround may be about the best option.
Well yes, you can reset it.
BUT the red screen is the smallest issue in your situation. I assume that NVRAM got corrupted somehow and now the unique configuration like IMEI numbers, Wi-Fi MAC address and modem calibration data all gone. The phone would still work, may even register into the network, and it's possible to restore IMEI/MAC numbers, but the phone won't work as good as it should/used to. This is a pretty serious issue. I can make an NVRAM dump from my device for you to program as a last resort, but you'd better try to solve it with the manufacturer first.
There's several GBA emulators on the Play Store. Here's a couple:

As for malware, just stay away from anything that appears to be too good to be true and stick to the Play store.
It's mostly if you're typing in another language than English that you need another keyboard. As an example I use Keyboard Designer for Swedish characters. You find some phone specific settings under Setting -> Intelligen assistance, like mini mode for apps that don't work well in the square screen layout, or Scroll assistance (scroll by swiping on the keyboard).
​
Double tap alt to use the numerical keyboard, and then tap alt once again to get back to the normal keyboard.
​
If some app don't work as it should, try removing it from from the app blocker under Intelligent assistance.
That is 100% correct.
Look at the photo of the packaging - it isn't shaped properly :
