Night clock issue

[xxxegoxxx]

So after updating the s6 edge plus to marshmallow, the night clock doesn't operate like it's supposed to. It keeps displaying the wrong time. Like this morning it was actually two hours slow and I would have to unlock the screen to fix the time issue.

My sister has the same issue on her S7, this is really because of the recent OS update. Android is really full of bugs esp. at early releases of their new software. I'm sure Samsung will release a hotfix or an update to fix it. On the mean time you can try to use a different clock app to replace your current one (while you are still waiting)
