However, if you’re still having problems we have one more solution. This one is a last resort, as there’s a small chance you’ll lose text messages, group conversations, or picture messages while taking this route. You shouldn’t, but it’s a possibility. We’re going to clear the app data for Android Messages.
Go to Settings – Pull down the notification bar and tap the gear-shaped settings button
Select Apps & notifications, then All Apps
Find and tap on Android Messages from the list
Tap on Storage, then select Clear Storage
Select Yes on the Delete App Data popup
This will delete any and all settings, files, app data, and customization. Basically erasing everything and giving Android Messages a fresh start. Your phone should save all of your text messages.
When you open your text app again following this step it may take a while to load. That’s because Android Messages is importing all of your text messages. So while you shouldn’t lose anything, don’t be surprised if you do, or pictures are missing/out of order. That’s why we recommend backing them up first.
