Sir, everyone can get through a single day even without a phone at all! This is a list for bugs, problems, and what users are asking for, some of them is what I saw many people demanding over the feedback app, for example, I don't find a need for a landscape start screen.
BTW, tracking your data usage is not working correctly on W10M, try for yourself to delete the old limit, and add in a new one and see what happens. Even the data readings if you change the day of the month will differ massivly. So it is another thing that is not functioning correctly in Windows Mobile.
