@Rontu2,
well not every conceivable test, because I really need convincing this is due to faulty hardware. It's more like coding and memory cache useage, here's why...
I did the test again using yet another email address - this time an iCloud IMAP address.
THE TEST: Inbox and Trash were empty at start, connected to wifi.
Step1: Receive 8 messages in Inbox (numbered 1-8)
Step2: WIFI >turn off (double check no network connection)
Step3: INBOX >move all messages to trash (delete all)
Step4: TRASH >delete 1 message
Step5: TRASH >move remaining messages back to Inbox (move all)
Step6: TRASH >exit Trash and re-enter to double check Trash folder is empty
Step7: INBOX >move all messages to Trash (delete all)
Step8: TRASH >How many messages are there? Its magic huh?
- I’ve repeated it a few times with small incremental variations. Attempt 2:
Step9: TRASH >delete 2 messages
Step10: TRASH >move remaining messages back to Inbox
Step11: Exit and close the Mail APP
Step12: Re-open Mail app
Step13: TRASH >check its empty
Step14: INBOX > move all messages to Trash (delete all)
Step15: TRASH > How many messages are there? Its magic huh?
attempt 3: reboot device (Home and Sleep button together). Restart device.
attempt 4: power off and restart device (Sleep Button).
A couple of observations more to the original title of this thread.
- on initial test a total 8 test messages all identical except differently numbered subject header:
-preview in 6 messages is blank and email displays…“not downloaded from server”
-preview in 2 messages displays…“message has no content” and email is blank. (kinda considered as normal behaviour)
more weird behaviour…after I’d moved these messages around a few dozen times, they actually changed! So I eventually finished with 6 messages with a preview and email that read… “message has no content”. Remember, it was only 2 when I started with correct preview, but the email was blank.
The others…1 message blank preview & message displayed “this message has no content”; the other message had blank preview & message displayed “message not downloaded from server”
Observed:
- iCloud inbox locks up when I deleted 10 mails at same time on a different test. (then need to close the Mail app and re-open.)
- Mailboxes view shows an account with a number of new messages received > but turn off wifi > open the account and Inbox shows as empty > exit Inbox wait a few minutes then Inbox shows messages (OK, but really, really slow considering it was handling 6 blank messages)
Hmm!
