Messager's name not displayed even when sender is entered as contact.

Why do some messages not have contacts' names on them, just phone number that they were sent from, even though they are entered as contacts?

quick contact showing two duplicate mobile numbers

Many of my contacts contain just one phone number, their mobile. Then WhatsApp identifies them and adds its own contact. These two contacts are merged and when viewing the contact I see only one number, as expected. However, apparently internally the G3 lists the contact as having 2 duplicate numbers. This confuses apps that try to automatically choose a default number to call (specifically, Conigri contacts widget). I can also see this in the quick contact popup. The contact shows with two entries of the same number. I can't work around this by choosing one of these as the default, because the contact details show just a single number. I tried to remove the number, which initially works as the WhatsApp number becomes the default, but then WhatsApp syncs, sees the contact no longer has a number and deletes its contact entry leaving me with a contact with no number.

Note that I previously had a Galaxy S5 and had no such problem there (so it is not a basic Android problem I guess).

I tried googling for the issue, but couldn't find it. How can I solve this?

requesting contact apk for Honor 4x (CHE2-UL00)

Hi everybody,

In my hnor 4x (CHE2-UL00), i can't put prefix or suffix when i save contact.
and also i can't write contact into "first, middle or last name".
my contact appear only "name" can't choose anything.

Can you put the name like "first, middle & last name" in Che2-L11 or other 4x version?
if that so, can i get the contact apk from it?

Thanks in advance!

P.S. sorry for bad english.
