This can not be overstated, I hardly use system apps on my phone as well, the truth is once in a while I go around checking my phone for apps I don't use regularly and delete them, for me the only mobile game I have is Chess, no more.
For social media, I have X (which I'm considering to delete as I don't use it often), whatsapp and discord for hive purposes as well as Ecency. That's all for me with my system apps, netflix and Mx player.
