I had the same issue and solved it by setting on the info.plist file the following values, on iOS 10*:
Status bar style = UIStatusBarStyleLightContent
View controller-based status bar appearance = NO
If you prefer directly in your Info.plist:
<key>UIStatusBarStyle</key>
<string>UIStatusBarStyleLightContent</string>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
