Android question: what have I done now???
 

Android on an Xperia z3.

Text messages I send no longer show as a continuing conversation, with replies also being missing. The only part of any text I can see is the first line, when I try to open it, it's not opening and I can't see the rest.

Have I inadvertently done something, or do I need a reset?

TIA.

If you google search you will see various answers, one of them is that the contact has '+' at the start of the telephone number. If you change that to 0 it might help. There are too many options to quote

Thanks, never thought of Googling it.
