Any device’s full potential may often be unlocked by having a keen eye for the hidden gems beneath the surface; the iPhone’s hidden functions are no different.
Your iPhone has many hidden treasures that are just waiting to be discovered, from iMessage features to brighten every conversation to generation-specific features that maximize the technology in any particular iPhone.
A set of volume buttons is a characteristic that is common to all iPhone models. Unlike many Android phones, which only have one volume button, the iPhone has featured two different volume buttons since its original release.
The two buttons on the left side of the iPhone are used for functions other than volume control.
Like so many other locations, the phone’s buttons can be utilized for non-volume operations in addition to a few useful chores that can be accessed with their assistance.
Whether you’re a photography enthusiast seeking tactile finesse, a safety-conscious person needing quick access to emergency services, or someone who longs to have a physical snooze button again, the iPhone’s volume buttons offer a range of interactions that go far beyond their seemingly straightforward purpose.
When you make an SOS call, your phone notifies your approved emergency contacts of your location and the circumstances using the information you provide in the Medical ID section of the Health app.
With regard to Medical ID, users can store their emergency contacts, allergies, critical medical information, and other details in this function.
In an emergency, anyone can access this information. Even if your phone is locked, the Medical ID is still accessible for first responders’ use.
Switching off the power and more
Beyond emergency services, another important feature of the iPhone could be accessed by briefly depressing the side and volume down keys.
The menu that offers access to Medical ID and the emergency call slider is where you’ll find the power-off slider. Turning off the iPhone is done by using the designated slider.
Users may also use this screen to disable the Find My function on their phone when it is in sleep mode. Just below the power-off slider, there’s a popup to turn off Find My.
Find My Device will no longer work if the device’s setting is disabled through the power off menu; you will need to restart it and enter the passcode again to locate it.
This control layer significantly improves device security by granting users control over their location data even when their phone is off.
However, this feature is more intricate than it seems. Using the volume buttons to access the power-off menu has a security risk. The power off slider displays, briefly deactivating the Face ID and Touch ID functions.
This ensures the gadget can’t be turned off and prevents someone else from being able to forcibly access it when locked.
controls for the camera
Contemporary smartphones are renowned for their capacity to swiftly and effortlessly capture moments, with the iPhone outperforming rival flagship devices in terms of camera capability.
One of the more widely known features of smartphone camera apps is the ability to use volume controls.
While some Android devices allow users to zoom in, the primary purpose of the volume keys on the iPhone is to capture images.
Instead of fumbling with the on-screen shutter button, users may snap instant images by simply pushing the volume up or down button.
This small function mimics the feel of a traditional camera, offering a cozy, tactile experience that some users might find more acceptable.
Moreover, this feature is not limited to shooting photos. To start recording a video, you can also utilize the camera app’s volume buttons.
Because it provides users with control and stability during the process, allowing them to grasp onto the device steadily and capture dynamic footage, this function is very handy for recording video material.
A video recorder’s volume buttons are helpful for purposes other than merely starting a recording. If the iPhone’s camera app is still set up to capture images, you can use either volume button to begin a quick shot movie.
Users merely need to release the button to stop recording. You may also press and hold the volume up button to switch it to “Photo Burst” in the Settings app.
The Notes app’s document scanning feature and the Camera app both utilize the volume buttons for taking photos.
When scanning a document into the iPhone, users do not have to wait for the device to properly frame the document. As an alternative, you can snap a picture of anything that’s visible in the scanner’s viewfinder by pressing either volume button.
With enough time and work, such scans can be edited to appear as precise as what the iPhone can accomplish automatically.
Alarm mechanisms
It can be a surprising habit to turn off the alarm in the morning. Apple has given its users the chance to go back in time to a simpler time when they are trying to snooze their alarm in the morning.
You can immediately stop the alarm when it goes off by using the volume up or down button. This will spare you the trouble of looking for the on-screen button and give you some alone time while you get ready for the day. This method of using the volume controls also applies to vibrating, quiet alarms.
Using the volume buttons to snooze occasionally proves to be more convenient than reaching for the snooze or smaller dismiss button first thing in the morning.
Similar to the snooze button, the volume buttons are likewise simpler to reach in the early morning mist.
Slapping the enormous snooze button on an equally gigantic alarm clock radio combo doesn’t exactly feel the same.
Remember that you must first ensure that snoozing is enabled before using the volume buttons to snooze an alarm.
If the snooze setting is not enabled for an alarm, the volume buttons will simply refuse it. The alarm is programmed to sound again at the next specified time.
Turning off phone calls and locating my
Picture this: a quiet moment or a crucial meeting cut short by a ringing phone. It doesn’t happen very infrequently. It’s simple to periodically forget to switch off your phone or even to switch it back on by accident.
The volume buttons on your iPhone soon create a barrier between you and anyone close and the ringtone you’ve selected when you receive one of these unpleasant robocalls. In far harsher situations, you can use the power button to reject or end a call.
The ringing phone can be muffled with a single press of either volume button. Using the volume button to end an unwanted call makes sense.
Controlling Find My notifications on the iPhone also heavily relies on the volume buttons.
The iPhone uses new buttons to secure your relationships and belongings in a world where those things are vital.
The position of your second Apple device can be found by pressing either volume button quickly to quickly muffle the otherwise loud warning when something close sends out a Find My notification.
As a result, receiving notifications is more manageable.
App features
Despite Apple’s best efforts to stop it, iPhone volume buttons can be utilized as tools for other app interactions.
the inventive usage of volume buttons in non-Apple apps—a feature that is usually free from Apple’s stringent constraints despite its usability.
By using this repurposing, a number of software developers have provided users with instantaneous shortcuts or actions, providing a haptic and seamless alternative to traditional on-screen taps.
One particularly straightforward approach is to utilize a counter app that allows users to tick up or down dependent on whether they use the volume up or down button.
However, employing volume buttons in non-Apple apps is a technique that should be utilized cautiously due to Apple’s app development constraints.
Maintaining a consistent user interface and preventing hardware control abuse—which can possibly mislead users or obstruct normal interactions—are given top attention in these standards.
Apple usually forbids developers from altering the functionality of hardware buttons in their apps as a result.
While some programs are able to effectively integrate volume button functionality while adhering to Apple’s standards, these instances are still quite uncommon due to the challenges these constraints pose.
Not only can developers not modify the behavior of the volume buttons, but users are also not allowed to use the volume buttons to run commands that were developed within the Shortcuts app.
But not everyone has been deterred by that. The volume buttons on your phone can theoretically be used to create shortcuts, but doing so involves using a complicated workaround function that connects an action to the volume.
Restart with force
At some time, everyone has either attempted or heard the sage advise to simply turn their device on and off again. Using the volume buttons to force an iPhone reset is a quick and simple solution in many cases.
When the device becomes unresponsive, sluggish, or has software problems, this can function as a reset to help restore it to a better state.
Users can force a restart by simultaneously pushing and holding the side button, the volume up and down buttons, and the volume down button.
The volume buttons here can be used to reach the shut-down menu, but the iPhone can also be turned off without the need for a slider by holding down the side button.
After turning off their phone, users still need to push and hold the side button down until they see the Apple logo on the screen.
What are roundabouts? A transportation engineer explains the safety benefits of these circular intersections
If you’ve been driving through U.S. cities and towns, you’ve likely noticed an increase in roundabouts replacing traditional four-way intersections. Some drivers embrace them as an efficient traffic solution, while others find them confusing or even intimidating.
But what exactly is a roundabout, and why is it becoming a preferred alternative to stop signs and traffic signals? Roundabouts are not just about traffic flow—they are a safer, more efficient, and environmentally friendly way to design roads.
Let’s break down what roundabouts are, how they work, and why they are considered one of the most effective traffic management solutions today.
What is a Roundabout? Understanding the Basics
A roundabout—also known as a rotary or traffic circle—is a circular intersection where vehicles move counterclockwise around a central island. Unlike traditional intersections controlled by stop signs or traffic lights, roundabouts operate using a yield-at-entry system, meaning:
✔ Drivers entering the roundabout must yield to vehicles already circulating.
✔ Traffic flows continuously, reducing congestion and unnecessary stops.
✔ Speeds are naturally reduced, leading to safer driving conditions.
Most roundabouts also include:
🔹 Splitter islands – Raised medians that help slow down traffic before entering.
🔹 Pedestrian crosswalks – Positioned away from the central island to increase safety.
🔹 Lane markings – Clear indicators help guide drivers into the correct exit lane.
The result? A smoother, safer, and more efficient intersection that reduces both traffic delays and accidents.
A Brief History of Roundabouts
Many people assume roundabouts are a modern innovation, but their history dates back hundreds of years.
Video : Roundabout Safety Benefits
- 1700s – Early versions of circular intersections appeared in Europe, particularly in England and France.
- 1800s-1900s – Washington, D.C. was designed with multiple traffic circles, inspired by European models.
- 1950s – The United Kingdom introduced the yield-at-entry rule, transforming roundabouts into the efficient system we use today.
- 1990s – The first modern roundabout in the U.S. was built in Summerlin, Nevada in 1990.
- Today – Over 10,000 roundabouts exist in the United States, with more being installed every year.
While roundabouts have been common in Europe and Australia for decades, the U.S. is now rapidly adopting them due to their proven safety and efficiency benefits.
Why Roundabouts Are Safer Than Traditional Intersections
One of the biggest reasons cities are replacing traditional intersections with roundabouts is safety.
1. Fewer Conflict Points = Fewer Accidents
A typical four-way intersection has 32 conflict points—areas where vehicle paths cross, increasing the risk of collisions. In contrast, a roundabout reduces conflict points to just 8.
This means:
✔ No head-on collisions
✔ No dangerous T-bone crashes
✔ Fewer high-speed impacts
According to the Federal Highway Administration (FHWA), roundabouts can reduce serious and fatal crashes by up to 90% when replacing a stop-controlled intersection. Even when replacing a traffic signal intersection, they reduce serious crashes by nearly 80%.
2. Lower Speeds = Less Severe Collisions
In a roundabout, vehicles enter and exit at lower speeds (15-25 mph), compared to the higher speeds (40-50 mph) seen at traditional intersections.
Lower speeds lead to:
✔ Less severe crashes
✔ Fewer pedestrian injuries
✔ Easier decision-making for drivers
3. Safer for Pedestrians and Cyclists
Roundabouts offer better protection for pedestrians because:
✔ Crosswalks are set back from the circular flow, allowing drivers to see pedestrians clearly.
✔ Pedestrians only cross one direction of traffic at a time, making crossings safer.
✔ Cyclists can either merge into traffic or use a designated bike path, depending on the design.
With these safety features, roundabouts significantly reduce pedestrian-related accidents compared to traditional intersections.
Efficiency: Why Roundabouts Improve Traffic Flow
Beyond safety, roundabouts are also more efficient than stop signs or traffic lights.
1. Less Waiting, More Moving
At a traditional intersection, cars must stop at red lights, even when there’s no cross traffic. In a roundabout:
✔ Traffic keeps moving – No unnecessary stops.
✔ Fewer backups – No long wait times during rush hour.
✔ Reduced driver frustration – No more waiting for a green light when there’s no oncoming traffic.
2. Eliminating Left Turns = Smoother Flow
One of the most dangerous and disruptive movements at an intersection is the left turn. Roundabouts eliminate left turns, forcing all vehicles to move in the same direction, improving:
✔ Traffic efficiency – No waiting for gaps in oncoming traffic.
✔ Driver decision-making – No confusion about when to turn.
3. Roundabouts Handle High Traffic Volumes Better
Unlike stop signs and traffic lights, which cause congestion during peak hours, roundabouts allow continuous movement, making them ideal for high-traffic areas.
Environmental Benefits: How Roundabouts Help the Planet
Roundabouts aren’t just safer and more efficient—they also have environmental advantages.
1. Reduced Fuel Consumption
✔ Less idling at red lights = less wasted fuel
✔ Lower speeds = better fuel efficiency
According to studies, roundabouts can reduce fuel consumption by up to 30%, making them a cost-effective solution for drivers.
2. Lower Carbon Emissions
Fewer stops and starts mean lower emissions, helping reduce air pollution in urban areas. Cities that replace signalized intersections with roundabouts see:
✔ Less smog and pollution
✔ Improved air quality
3. Less Road Maintenance Required
✔ No traffic signals = lower maintenance costs
✔ Roundabouts last longer than traffic lights
With less infrastructure to maintain, roundabouts save cities money in the long run.
Challenges: Why Some Drivers Struggle with Roundabouts
Despite their many benefits, some drivers remain hesitant about roundabouts. Common challenges include:
🚦 Confusion about yielding – Some drivers don’t understand that they must yield to circulating traffic before entering.
🚦 Merging issues – Drivers unfamiliar with roundabouts sometimes hesitate, causing unnecessary slowdowns.
🚦 Exit mistakes – Some drivers find it difficult to choose the correct exit and miss their turn.
However, studies show that once drivers become familiar with roundabouts, their confidence improves significantly.

Final Thoughts: Are Roundabouts the Future of Road Design?
Roundabouts are more than just a traffic trend—they are a safer, smarter, and greener solution for modern transportation. With their ability to reduce crashes, improve traffic flow, and lower emissions, they are quickly becoming a preferred alternative to traditional intersections.
🚗 Safer roads, fewer accidents
🚗 Smoother traffic, less congestion
🚗 Lower fuel costs, reduced pollution
As more states adopt roundabouts in urban and suburban planning, they will likely become a permanent feature of America’s roadways.
So next time you approach a roundabout, embrace the change—it’s making our roads safer and more efficient for everyone!
