Samsung 6S randomly loosing contacts and not notifying of text messages

[AC Question]

My Samsung 6s is randomly loosing contacts and occasionally not notifying of text messages... For example, the other day, I got a text message from my fiancee and her name did come up.. the next time I got a text from her, her name was gone and it showed her phone number.

When I did get her contact info back, it came back with old info.

Hello! Welcome to Android Central. You should boot your phone into recovery mode by
Power Down the Galaxy S6
Press and Hold the Power Button, Volume Up Button and the Home Buttons at the Same Time
Continue Holding These Buttons Until You See Some Blue Text at the Top
When You See the ‘Recovery Booting….” Text, Then Let Go of These Buttons
Wait Until the Galaxy S6 Fully Boots into the Recovery Mode

Once you have done this, select wipe cache partition. Hopefully this will fix those bugs. If this doesn't work, you should do a factory data reset.
