S6 / edge missing icon fix
For anybody having problems with lost quick icons there has been a fix released
Go to galaxy apps - search Quick panel restore. - Install and run.
Hope this helps everyone.
A sticky would be helpfull
Go into Samsung app store search for quick panel restore. Install and run this is Samsung's fix for the problem. Did this myself and quick toggles are back but remember you will need to edit them to put the correct toggles back at top
Looking around this seems to be a problem with Samsung text to speech. They released an update which caused a software glitch the development team are aware of the problem. In the meantime the workaround is settings - data usage - turns on / mobile data
