Who did recommend to do a factory reset every 2-3 updates? If you have some official Samsung documentation stating that, could you post it please?
Old files and corrupt files should be deleted by clearing cache and data. If anything else is left on the disk then surely it is bad coding from the people writing the update.
Your phone might be a very good one or your usage does not bring the issues that other users are facing. In my experience, problems with calls, camera recording issues have not disappeared with any amount of factory resets, clearing system cache or optimising apps.
You seem to be very sure about lazy, inexperienced users without even having access to the user's device or the user's technical knowledge .
I think a more respectful language will improve the debate. So, your phone has zero issues. Is that a sufficient argument to imply that every phone has zero issues as well?
I did ask you if you have any official information from Samsung stating that a factory reset is recommended every 2-3 updates? Was that a personal opinion?
I don't know when or where you got this phone but in the UK this phone is already 6 months old.
Bugs are normal occurrences but usually in less used features. These phones have had problems even with phone calls.
Again, nobody is saying that you must have the same problems that someone else is having. I have two S22 Ultra in my household, I have seen the same issue in both of them but I cannot claim that every phone has it.
Most people here talk from personal experience. Some people received their S22 a week or so before the release date. Yet, many of us had the delivery delayed at least three times.
The fact that you cannot replicate any of the issues it does not mean that they are not happening for other users. Both of our S22 ultra have an issue whilst recording on slow motion mode, at least one other user here has the same problem, yet I cannot state that every phone in the S22 series has the same issue.
So, your argument is that all phones are identical. Hardware and firmware are the same so there are no other variables in the manufacturing process. What do you explain the differences on the same model for pretty much every manufactured device?
