My wife and I have the Doro 8030 and are experiencing the same problem. The pictures we attach to our contacts are being deleted and there is no apparent reason why.
I have reset both phones to factory settings and then reloaded contacts and the photos. For about 24 hours everything was fine. Then last night (29th – 30th Sept) the pictures were deleted from the contacts book. The pictures are still on the phones.
Our contacts are synced from Outlook to the contacts books. Would that be the problem?
I hope you can provide the solution. Thank you.
