One can easily access your content with just a flip and everything is there for them to view.We most times wish we can hide that sensitive content from the public just to have a little privacy. if that is your wish, then here is the method you can employ in achieving that.
On Android, hiding the sensitive notification content option was introduced with Android Lollipop and was much required after Android adopted iPhone-like feature to pop these notifications directly on the lock screen. The phone asks you the question if you would like to hide content in notification when you set up your device initially. But if you missed out the settings there, it can be found under Sounds & notification settings. Here, scroll down to the Notification section and you will find an option that When device is locked. Just tap on it and select the option to Hide sensitive notification content. That’s all. Next time, you will get notification from the apps, but the content will be hidden on the lock screen. If you tap on the options App Notification, you will see a list of all the apps installed on the device. Here you can block any of the apps from notifying you or even make it a priority that brings it top of other notifications and makes sure you don’t miss out on them.
On iPhone, there are two ways in which you can control the content of the notification on an iPhone and the first one is to go through the settings of each individual app. For example, apps like WhatsApp and Facebook Messenger give you the option to hide sensitive content from the lock screen. There are many apps that support this feature and you just need to look for the option. For messaging, you can just turn on the Do Not Disturb option for the particular thread. You can also mute the notifications from iPhone settings. Just look for the app you wish to disable the notification and turn off the Show on Lock screen option. The only downside is that the option if disabled from here you will not get any heads up on the lock screen. You will just get the notification sound and everything, along with the name of the app, will be hidden from the lock screen.
Therefore, always look for the first option to mute notification content before choosing the built-in settings.
