How do I restore Apps icon?

Zoom on any page with apps, then click "+" to add hidden apps. Now scroll down and check the missing apps and click ok. Then click again on "+" and uncheck the apps. Now the missing apps will appear in your menu. This is a bug that came with the new system update.

"Go to: settings > home screen style.

Set simple style, wait a few seconds and then come back to standard.

Hope I been helpful."

"Home screen>pull down finger to open ""search"">try to search it.

If not than go to play store for that apk and reinstall it."
