Operating an iPhone can be very easy and at times somehow complex and complicated. Though easy to use and go through as you are competent enough to learn, it’s working in any means possible.
It comes with a manual which you can use while operating it and here you can learn all you want from the phone.
At times it may have so much to hold that the storage is demanding and you need to delete some apps.
It is so easy to do this, simply long press on the app that you need to delete then you will see the uninstall option.
Click uninstall, and all is done.
