When you try to install modern YouTube APKs, you are greeted with a "Parse Error" or a message stating, "This app is incompatible with your device." This is because Google ended support for Android 4.4.2 back in August 2023.
If you're looking for a more lightweight version of YouTube, you can try YouTube Go APK, which is optimized for older devices and slower networks.
Download the .apk file on your computer first, scan it with VirusTotal, then transfer it via USB to your Android 4.4.2 device.
