iphone 12 touch screen slow or unresponsive in mail app
This problem occurs only in the mail app all other programs/apps seem to be perfectly ok.
I open the mail app onto all inboxes (I have 3) and they all show no mail. After a few seconds they populate but touching a mail item produces no immediate response. After around 3-4 seconds the mail item appears. On return to the inbox there are gaps in the mail lists which again populate after a few seconds or sometimes (not always) when I scroll up or down.
I often delete mail directly from the inbox list but left to right swiping is again very slow to respond, up to 5 seconds. It initially appears not to have worked at all but after a few seconds the item disappears.
I’ve tried resetting my phone using both a normal power off and also using the up/down volume buttons then holding the power button but the problem remains.
The problem started yesterday. My iOS is up to date and has not been updated recently. Any suggestions or comments would be gratefully received.
