What do you mean? I don’t think any other operating system even comes close to Windows in regards to backwards compatibility. Most software designed for Windows 98 will still run fine on Windows 11.

There are thousands lines of code in the NT kernel with patches for specific programs. There is even a line patching an incompatibility with Lego Island, lol.

The hardware is good, the software sucks. It’s not even Samsung’s fault but unless you only use a few selected apps, tablet support is usually pretty bad.

Realme belongs to Oppo which belongs to the same parent company as OnePlus (BBK). They share a lot of technology and often OnePlus phones are really just rebranded Oppo phones.
