There are many secret skills in the settings of iPhone, iPad, etc. Among them, the often overlooked "auxiliary use" actually contains many practical functions silently, or you already know it, but don't know when to use it? Here we are Just sort out a few needs that can be solved with "auxiliary use", maybe you can draw inferences from one case and know how to use these hidden functions.

"Tap on the back" to send a real-link text message in one second without touch

It seems that the joint system will not be withdrawn for the time being. How did you scan the barcode of the joint system in BR82 this year? The normal process is to turn on the camera, take a barcode, click 1922, and send it again. It takes a lot of time to make several points in the middle. Fortunately, many netizens on the Internet have made a shortcut to send the real link system, which can simplify the whole process. If you cooperate with The "back tap" in the auxiliary use basically can automatically send a text message without touching it after unlocking. The process can be completed in almost one second according to the QRCode. I have used it for a while, which saves a lot of time virtually, and can be completed with one hand.

1.) Download the real-link shortcut first. You can find a lot of them by typing keywords. I use this set myself. I can install the shortcut by clicking the link on the Internet on my iPhone. Thank you for the author's contribution!

2.) On the phone, go to Settings→Accessibility→Body Actions and select Touch→Scroll to the bottom, turn on "Back Tap", specify the action you want to turn on after double-clicking or triple-clicking, and press down Volume, you can see the real-link shortcut that has just been installed, and it is completed after specifying.

Just want to increase the font of an App alone

I often hear elders complaining that the font of the menu of a certain app (such as LINE) is too small, or it is made gray to make it difficult to see.

Intuitively, we will go to the screen display to enlarge the text, but here is to enlarge the font of the entire mobile phone. If you only want to change the text size and clarity of a certain App, you can go to Settings→Auxiliary Use, and pull to the bottom, You can see "Individual App Settings". Here you can add different apps to make individual settings.

In addition to changing the font size, there are also settings in the settings to check less dynamics, turn off auto-play videos, etc., but I have tried common apps such as LINE, Facebook, and Shopee. Not all items can override the settings of the app itself. is more troublesome

The place. In particular, the text size can only be changed for the text that supports "dynamic font level", and many App menus do not have such fonts, so they cannot be made larger or smaller.

Still no way to increase the font size

What should I do if I encounter an app that is not dynamic word-level like the above, but needs to be enlarged? This time had to use zoom.

Click to use the assistant and you can see "Zoom" immediately. After turning it on, first set the "Zoom Area" to see if you want to zoom the window or the full screen. The former is to draw a local area, and the latter is to zoom in on the entire page. You can see personal reading and material selection. Then set the maximum zoom level, which is usually less than 2 to 3 times for most people.

Later, when you need to zoom in, you can double-tap the screen with three fingers, and the page will be zoomed in to the multiple you set, and you can slide the page by dragging with three fingers.

This is not only available for elders to enlarge fonts, but also when viewing PDFs on mobile phones or iPad minis, or when visiting shopping websites on mobile phones, when encountering pictures that cannot be enlarged, it is very convenient to see the details clearly.

Play files with zoom

When you need to change the manuscript on the mobile phone, you can also use the zoom to make the text on the screen larger, so you don’t have to look so hard, and there are two very useful functions for typing, “moving with focus” and “smart input”.

Moving with the focus will keep the zoom center locked on the text input cursor, so you don't have to manually move it to the input field.

Smart input is that when the typing keyboard appears, it will switch to zoom in with the window, and only the part of the text will be enlarged. The keyboard still maintains the width of the phone for easy clicks.

Avoid distraction, prevent accidental touches and interference in games

In the auxiliary use → general column, there is a "guided use mode", I don't know what this function is doing just by looking at the name...

Simply put, it is to force the iPhone and iPad to stay in an app, because at this time, it will restrict the pull-down notification center, slide back to the desktop, switch the touch function of the program, and the side buttons, and cannot use Siri. It means that you cannot start other programs at this time.

Also because it has these characteristics, it can be used to prevent accidental touches when playing games, so as not to accidentally leave the game or press to sleep. Or use the iPad in online classes, you can also use it with a password to force the child to help or concentrate on this app during this time.

After the "Guided Use Mode" is turned on in Assisted Use, open the app/game you want to use, and then press the side button three times to activate this mode.

More important is the setting after enabling.

You can see "circle the area on the screen that you want to disable" on the screen, this suggestion is not. want. hand. itch. go. painting!

Because the unfamiliar will not know which areas are circled, if you do doodles, there may be a horrible problem that you cannot touch everywhere. Don't move it, just follow its original settings.

Instead, the "Options" in the lower left corner can be set.

It allows you to set which functions to keep during the "guided use mode" (switch to green to indicate that it can still work), usually touch and keyboard will be turned on, if you play games, the volume button can also be turned on; if you want to set Set the length of use, you can open the time limit, select a period of time, and a sound reminder will be heard when the time is approaching.

When everything is ready, click Start.

At this time, you will find that the horizontal bar below is gone, you cannot pull down to see the notification control center, and the side buttons do not work (if the option is not turned on).

But what if there is a call at this time?

At this time, the incoming call will be automatically turned into rejected (the other party will hear that you are busy), only a notification will appear on it, and the ringtone will not cover the game sound, which is equivalent to turning both incoming calls and notifications to Do Not Disturb .

You can still press the key combination with the fried chicken in one hand

This is a function that belongs to iPad (maybe Mac has it too, I didn't look for it). When pairing with an iPad external keyboard, you should use key combinations very often, such as Command+space key to call out search, Shift+Command+3 to take a screenshot, etc. To know what shortcut keys are actually available with the keyboard, you can long press Command to display the list.

But we are often very busy. For example, we are talking on the phone with a mobile phone in one hand, or nibbling on fried chicken. When we don’t have time to press the shortcut keys with both hands, we can go to Auxiliary Use→Keyboard→Turn on Key Hold.

This function allows you not to hold down at the same time, as long as you press the desired key, you can also perform the function of the shortcut key, so press the three keys Shift--command--3 in sequence, you can also take a screenshot on the screen. will show you what key you pressed. (In fact, it doesn’t matter if it’s not in order, just the function key and then the letter key)

In Display and Text Size, turn on "Reduce White Point Value" to further reduce screen brightness.

For old mobile phones, you can go to Accessibility→Dynamic Effects and enable the motion reduction effect to save power. (When the battery health of i13 ProMax is not good in the future, you can also turn on "Limit Frame Rate" here)

When it is muted and you are afraid of missing a call, in addition to using the Apple Watch to remind you, you can also turn on the "Blink LED light when you receive a reminder" in the "Audio/Visual" of the auxiliary use, so that when you call, the fill light behind you will turn on. Blinking continuously

When paired with AirPods or Beats headphones, you can also adjust the high and low frequency proportions of the headphones in audio/visual.

If you find a suitable auxiliary project, you can also choose to join the control center to quickly activate it.

Although the original intention of auxiliary use is to help users with inconvenient limbs, eyes and ears, many functions are still very useful for daily situations. You can study and take a look when you have time. It is really a treasure trove.
