1) navigation bar accidental taps is common, many people suggest to use gestures, but some people don't like it. For this I have a solution. Download the navstar from Goodlock or finelock. Give it required permissions and the turn on show and hide button. Then you'll see a small dot which is in navigation bar. Double tap on it and navigation bar will disappear. Now swipe from down and double tap that button again then navigation bar will be visible. It's very helpful.
2) if you're giving phone to small kids then activate kids mode on your phone and set lock. You can add apps like YouTube kids etc.
3) Some people eyes are sensitive by animations then turn off animations in accessibility settings in vision enhancement part.
4) to protect your phone from overheating use thermal guardian and set the temp to desired limit. You can adjust additional setting like when phone will heat refresh rate will set to 60hz etc.
If you're facing any issues like these then comment below. I will try to help.
