Text Messaging Lag

[AC Question]

I have an issue on my Galaxy S6 Edge when texting but only to one specific contact. All other contacts have no issues. The messaging app lags a lot. It lags when opening the keyboard, typing and sending. I have tried wiping the cache partition, clearing the messaging apps cache, and have tried using a couple different keyboards. Nothing seems to fix the issue. The Google Keyboard i tried using helped with the lag when typing on the keyboard but didn't fix the rest of the lag.

Any suggestions?

Thanks

Check that particular contact and make sure there's no emojis, special characters or similar included in his info.
