no it is not the ringing tone
if you are new to iPhone 8 or any other iphone you might think true tone is a default ringing tone or something like that but no it is not.
this system was first on iPads and now it is on new iPhones like iPhone 8 but they were not on older iPhones like iPhone 5, iPhone 5S, iPhone 6, iPhone 6 Plus or iPhone 7
so what true tone does is it adupts your iPhone 8’s diplay brightness according to the enviroment brightness condition
To turn on or activate the true tone feature in your iPhone 8 you have to
- Go to”Settings”
- Now go to “Display and Brightness”
- and at last swtich on the toggle next to “True Tone”
and now you are done, now you will not have to change the brightness of you iPhone everytime the lighting condition changes. It will automatically adupt to the enviroment you are in.
