I have a samsung Ace 3 dual sim. Android 4.2.2.
I have a number of foreign contacts that I call using tesco international calling card. I store these with the calling card landline first, a pause and then the contact number ending with a hash (020811111111,0027123123123#)
This has worked fine for years now, but I recently noticed that a certain contact number had had the last 6 or 7 digits erased. When I tried to edit the number and add the missing digits, the phone would not allow any further additions to that line/number.
I have checked other numbers stored in the same way (020811111111,0027123123123#)and they have the full number stored correctly.
Any advice on how I can add back the missing numbers on any contacts affected like this?
