One UI 2 and Android 10

Samsung like thia

nahi milega samsung os policy mien sirf two major updates hi milne wala hai no more os update
even court can force Samsung to provide the third major updates

samsung says that there might the possibility of facing major bugs , and by the way we dont need that much os level in any smartphone around the world two major update is enough for the mobile os level platform or else if Samsung provides the update a major bug can exploit the mobile think of that

phir baad mien mat bolna ki Samsung ne yeh kharab kardiya woh kardiya phir pura platform mien bas os ko leke complain par complain karo ge

android fragmentation is also another thing that also need to be solved if google ditches the android in favor of fushcia os then it could be possible for the google to give 4 to 5 years of os level support try to understand the android fragmentation and the policy of Samsung even flagship aren't getting the 3 major updates

until and unless you own a google or oneplus devices which is ultimately impossible to own due to its pricing
