Ever since I've tot good looks my system UI shows an error. The error is shown because I've turned the feature on from developer options which states show background app crashes. I don't know if this is sasmungs matter but the app good lock I think is causing issues to the main structure of UI. If this is common please tell me way to fix it. Every time I restart my phone all apps which have main setting (E.G System UI,Google play services, Google carrier services) all have an error.
