why are two icons on phone working

[Android Central Question]

the call and video chat icons on messenger are not highlighted or outlined it's as though they are dead I have tapped on them several times and nothing happens I've uninstalled and re installed messenger and facebook.

It's mainly due to some software issues. Try the following steps to get it sorted out:

1. Visit Settings ➡ Apps ➡ All

2. Select each of the Photos apps one by one and compare their version numbers

3. On the Photos app with the lower version number, touch the Disable button
