I have this same problem and more..Hi. In my phone (Redmi 4 Prime), when I go to the SMS, in the first time it shows the name of the contact but after I go down or up in the page of the SMS and the name dissapears and only shows the number of the contact. Is there anyone with the same problem?
Perhaps it is from your locked apps. I experience the same with keep. If you remove Gmail from locked apps, it will work.Redmi5 plus - after this update Gmail app does not work anymore. When I run it, it gets stuck without being opened, blocking the whole Android (gestures do not work). I could only head to settings and uninstal that app from there. Please fix it, it is important!
