A few moments ago Apple has released an iOS 12.3 update for some improvements in almost all aspects. Why is the iOS 12.3.1 update so fast launched? Apparently, there are some bugs generated by iOS 12.3 which is a major update from the previous iOS 12.2. The bug that arises is about calling and receiving calls using VoLTE.
Some of the improvements Apple made to update 12.3.1 according to the changelog released by Apple.

We can updates made by using 2 methods, the first way is by direct method or OTA and the second method using iTunes. For the first way, we can directly from the iPhone or iPad that we have, how?
Steps to update OTA
As I have already done to update the OTA, friends immediately hold the iPhone or iPad and we start using the application settings. The steps are as follows:
Settings> General> Software Update
After it will load for a while to check the latest iOS updates and friends can click "download and install" to the next stage. To update this OTA the internet network must be stable, required to connect to a wifi network. Why is WiFi? Because the automatic wifi network does not use the usual mobile network and is usually a more stable home internet network.
What about manual updates?
We use iTunes media to make manual and updated to use the latest iTunes. Is there anything other than iTunes that must be prepared? There is. Friends must download the iOS 12.3.1 firmware file separately.
In accordance with the way the update that I have explained can be done manually and in OTA for iPhone and iPad iOS. Now for iOS 12.3.1, you can treat it with that.
