Your mobile secrets and tricks that you probably didn’t know | Your technology | Country

A couple of back blows to make Photograph, turn down the ring volume automatically when starting work … It’s easy not to remember that a mobile phone is, above all, a high-end computer capable of doing many things for the user, and performing them automatically. On the other hand, the platforms continue to advance by leaps and bounds by incorporating new features and learning from user behavior. Do we know well all the tricks and secrets of the mobile? We pass, on both iPhone and Android, some of the most interesting.


It is not necessary to unlock the mobile phone to take a picture

Did you know that you can take a picture without having to unlock your phone? In the vast majority of Android mobile phones, double pressing the power button will activate the camera, even if the device is turned off; In the event that it is not activated, this can be done in the system settings (by customizing the function button).

Receive urgent notifications even when wearing headphones

“It’s one of the jobs I use the most,” Christian Collado, Andro4All Blog Coordinator, explains to EL PAÍS. It mainly consists of receiving important audio alerts, even if you are wearing headphones; Let’s think of a crying baby, a doorbell, waiting for a parcel or simply wanting to be aware of what is happening around us. Once activated, it uses your mobile phone’s microphone (or smartwatch, if you’re wearing one) to pick up and identify common sounds, such as a doorbell, a smoke detector alarm, a phone, or a baby’s cry. To activate it, you have to access the accessibility settings of the system, and enable the option called “Audio notifications”.

Unlock the phone automatically when you get home

Android allows the use of trusted places thanks to a function called Smart Lock, which deactivates the screen lock in certain locations or when connected to certain devices (for example, a car). To activate it, just go to (its location and scope depend on the manufacturer) Settings / Security / Advanced / Smart Lock; It can also be located using the settings finder. Once there, select the trusted devices or sites where you want the device to remain unblocked.

See all notifications from the past day

Managing notifications can be a real nightmare and the tendency – recommended – is to deactivate or ignore unnecessary notifications as soon as they are consulted. Now, what if we want to restore one of these deleted notifications? Android since version 11 introduces a valuable function: the notification history, in which notifications received on the last day are kept. To access it, go to settings and type “notification history” in the search engine and select the option you want to check.


Two taps back… and take a selfie

Not many iPhone owners know that they have an additional – invisible – “button” configured on their device. We refer to the back of the device which, thanks to its accessibility features, can be configured to the user’s desire. “When I click twice, the lamp activates,” explains Pedro Aznar, founder of the Applesfera blog. “When there are three touches, the camera is activated.” In fact, everyone can set it as they like in Settings / Accessibility / Touch / Back Touch, and choose the function that suits them best.

“Hey Siri, take a picture (or turn on the flashlight)”

Apple’s virtual assistant has been hated and appreciated in equal parts due to its uneven performance, but the truth is that it is able to perform very useful functions. One, not so well known, is to ask him to take a picture of us out loud (the only limitation is that Siri only opens the camera app, but does not press the shutter). In the same way, and in the dark, we can ask “Hey, Siri, turn on the flashlight,” and the light will turn on. The assistant is able to perform many basic functions and it comes down to trying until you find one that solves everyday tasks.

Shake to undo…almost everything

Another function that is not well known among iPhone owners is “Undo” (equivalent to Control + Z), which is performed on the device by shaking it with your hand. That’s right, if you can undo almost any function performed with a short flick of your wrist: a typed text, or a recently deleted email … By the way, this gesture was almost of narrative origin: Scott Forstell, one of the main characters in iOS at the time , asked his team to come up with a way to add the rollback functionality to the iPhone; One of its engineers humorously suggested it should be shaken up: Forstall bought the idea and the feature is already standard on the machine.

a key? It’s better to write using gestures or even dictation

Experts have made it clear that pressing the keys of virtual keyboards on mobile phones is not the fastest way to type per se, and with a few exceptions, getting used to gestures is faster. Not all iPhone owners know that the device’s keyboard natively supports swipe typing: it involves moving your finger from one letter to another until the system delivers the desired word. Thus, to type ‘house’ you will have to go through each of its letters without lifting your finger from the keyboard and when you see the suggestion at the top, lift your finger. This way, in the end, is faster than the traditional method, but it’s not the only one: iOS has greatly improved its dictation ability in the latest version of the platform and made very few mistakes, making it an alternative to consider (accessed by pressing the microphone at the bottom of the keyboard).
