There are so many bugs in iOS that are years old and still unfixed.<p>One example is the cellular-data draining bug[1]. The only "solution" for this is to wipe your device, and set it up again, <i>without</i> restoring any backups, at all. Which makes the whole point of backups of the device totally pointless.<p>For a company that spent $6B+ on a (now mostly empty) campus, you'd think they could spare a few $million into proper QA/Testing.<p>[1] <a href="https://mjtsai.com/blog/2019/07/26/broken-ios-cellular-data-switch/" rel="nofollow">https://mjtsai.com/blog/2019/07/26/broken-ios-cellular-data-...</a>
Uh.<p>I wonder if this can still be triggered when the Home application has been removed from the device? I expect so as IIRC builtin-in application removal is really just hiding them and all the functions are part of priviledged bundles shipped with the OS.
