Also note China modernized faster than any country. China went from farming-based to post-industrial in about 30 years and population behaviours and beliefs didn't follow it at same speed. So they have more hicks with ability to damage stuff than most of Africa and Central Asia
I do wholeheartedly agree that Samsung writes shit software tho, but their customizations for the last seven years stopped frying my phone. (S2 was okay, S3 was such a dumpster fire of a phone caused by Samsung's deplorable coding)
I have the impression that OS restrictions imposed by Google on latest versions of Android and - perhaps - the move to Kotlin improved it. I have been using a S10+ and had no issues with software. Crappy software can be removed without root using ADB and, in my region, Samsung does not bundle carrier crap (except stupid Facebook stuff that is still present in S10 and even S24 series)
