What's wrong with iPhone

[Mme4]

I just lost half of my contacts on my iPhone 4. This happens often! Also about 15 emails have the mailer_daemon notice. What's up please??

Regarding the contacts, have you set up a sync service such as icloud or gmail? The mail problem is likely related to your email account.

I did have linked to iCloud.

If you had your contacts synced to iCloud but they somehow get deleted by someone other than yourself... then you might check to see if any nude pictures of yours have been leaked online via thefappening

The mail problem is with your email account (Yahoo?), not your phone.
