Speed Up Your iPhone by Manually Clearing the RAM



Have you ever found yourself messing around with your iPhone, only to have it start to feel a little sluggish? It feels like everything you want to do takes longer than it should. Launching Twitter should happen in an instant, but it doesn’t!

Maybe you need to flush your iPhone’s RAM. I’m not talking about manually quitting all of the apps running. Rather, I’m talking about a lesser-known technique that will get everything out of RAM and let you feel like the phone just turned on.

The first thing you need to do is hold the power button until “Slide to Power Off”appears on the screen. Don’t slide it though! Instead, press and hold the Home button for a few seconds, and you will be placed back on the Home screen with a fresh slate as far as your RAM is concerned.


Don’t believe me? Double-tap the Home button. You’ll see that the apps you were running are still there, but if you click one, it will need to relaunch as if you were launching it from its icon.

Also, it should be noted that iOS generally does a good job of managing memory, and you shouldn’t need to do this often. But if something goes wrong, it’s a nice trick to have in your back pocket!

How to Use iPhone 6s as a Scale to Weigh Items



The 3D Touch display on iPhone 6s and iPhone 6s Plus is able to detect pressure applied to the screen in order to serve the 3D Touch pop and peek functions, but with the help of a little third party web app you can transform the iPhone and 3D Touch display into a fairly precise scale.

Turning the 3D Touch equipped iPhone into a scale measurable down to hundredths of a gram is simple and you don’t even need to download anything:
  • Go to the scale webpage from the iPhone with 3D Touch display
  • Lay the iPhone down on a flat and steady surface, then place a metal spoon or something similar* onto the screen – the items rough weight should appear on screen but you’ll be using this to hold other items to weigh, thus hit the “Tare” button to zero out the scale to “0” with the spoon on the screen
  • Now place your item(s) to weigh in the spoons cup to see that items weight

In this example, a USB thumb drive is being weighed:



You’ll find the results are quite accurate as long as you’re delicate, and the weight measurement is offered down to hundredths of a gram all the way up to 385 grams, the maximum amount of weight it can detect.

In this example, a piece of black anthracite is being weighed:


* For best results, find a spoon that is somewhat flat on the bottom so that it doesn’t roll around or move much. Also, be as delicate as possible when placing items into the spoon to weigh, if the spoon moves at all or rolls around, you’ll quickly discover the weight of the spoon becomes included in the weight of the item and the measurement is way off. You need to use a metal item so that it is conductive, things like plastic, wood, cloth, and paper won’t register on the touch screen.

If you have adjusted your 3D Touch screen sensitivity settings you may find the screen is a little more or less sensitive to this app, so consider changing it to the middle setting if it’s all over the place.


This is a fun proof of concept but it can be a little finicky, so you probably shouldn’t plan on using this for anything serious, whether in the kitchen as it could likely botch a recipe (it said 2 grams of jalapeno powder, I swear!), and especially so if you’re trying to be a Walter White or Pablo Escobar.

Anyway, since there are no downloads required and it’s as easy as loading a web page onto the iPhone, it’s fun to play around with.

How to Enable Wi-Fi Calling on an Android Phone


Wi-Fi calling allows your smartphone to place and receive phone calls, as well as send and receive SMS messages over Wi-Fi instead of the cellular network. Your phone will seamlessly hand off to the cellular network when you move out of Wi-FI range.

Android phones have supported this for longer than the iPhone has, but often just with customized Android devices purchased from the cellular carrier itself. There are also other Wi-Fi calling solutions you can use, including Google Hangouts, Google Voice, and Skype.

Enable Android’s Wi-Fi Calling Support


This feature is now integrated into the latest versions of Android in a more standard way. One day, you’ll hopefully be able to get any Android phone and enable Wi-Fi calling on any cellular carrier’s network if that carrier supports it, just as you can with iPhones.

If Wi-Fi calling is an option, you should find it in a standard place. Open the Settings app on your Android phone and tap the “More” or “More Settings” button under Wireless & network.


You’ll see a “Wi-Fi Calling” option here — activate it to enable the feature. If you don’t want to use Wi-FI calling, you can disable it from here, too.

This option won’t appear unless you’re using a phone with Wi-Fi calling support and are connected to a cellular network that works with it. But this is a quick way to check if you can currently use Wi-Fi calling. This option should hopefully become more standardized and widely available in the future.

As this is Android, it’s possible that your cellular carrier’s customizations — or the manufacturer’s customizations — have put a “Wi-Fi calling” option in a different place in the interface. You may need to search for the name of your smartphone, “Wi-FI calling”, and possibly the name of your cellular carrier.


Use an App Instead


Don’t see the “Wi-Fi calling” option there? Your cellular carrier may not offer this feature, or it may not work with your specific device. But there are other solutions you can use it you want to call and text from Wi-Fi.

Google’s Hangouts Dialer app will allow you to place phone calls from a Wi-Fi network. Most calls to the US and Canada are free, so this is an easy way to place calls to the US and Canada from a Wi-Fi network. If you don’t have a Google Voice account, the recipient will see one of Google’s seemingly random phone numbers appear on their caller ID.


If you’re in the US, you might want to sign up for Google Voice. This will give you a dedicated phone number, and you can receive and place phone calls and participate in SMS conversations over Wi-Fi using it. Unlike some competitors, this is completely free — as long as you’re communicating with someone in the US or Canada.

Other solutions include Microsoft’s Skype app. It can be used for traditional phone calls and SMS messages all over the world, although that will cost you some money. It’s not free in the USA, as Google Voice is.


Of course, for communication, other apps that let you place audio calls and send text messages without relying on traditional phone numbers can also work. For example, you could have audio and text conversations with Google Hangouts, Skype, WhatsApp, Facebook Messenger, and others. These all natively work over Wi-Fi or a cellular data connection, so you can use them even when you don’t have a cellular signal. The above solutions are only really necessary if you want to send and receive phone calls and text messages from phone numbers.

iOS 9.2 Beta 4 & tvOS 9.1 beta 3 Released for Testing


Apple has released the fourth beta of iOS 9.2 to users participating in the public beta testing and registered developer programs. The new iOS 9.2 beta build arrives as 13C5075 and is compatible with all iPhone, iPad, and iPod touch hardware that can run other version of iOS 9. Additionally, Apple has released the third beta build of tvOS 9.1 for the new Apple TV.

Users currently running an earlier version of the iOS 9.2 beta can find the beta 4 update within the Software Update section of their Settings app. Additionally, users in the developer beta program can download IPSW for the latest build directly from the iOS Developer Center.

Similarly, users of existing betas on the new Apple TV can download the latest update from the Software Update mechanism, or start the download from the developer center and use iTunes and a USB cable to complete the installation.



iOS 9.2 seems primary focused on maintenance and bug fixing, as there are no known new major features or significant additions to the release. 9to5mac notes that the new version does have Arabic language support for Siri and support for an AT&T feature called NumberSync.

Currently, iOS 9.1 remains the most recently available final build of iOS for iPhone, iPad, and iPod touch. On a related note, a new build of iOS 9.1 was released today specifically for iPad Pro users, but given the minor incremental difference in build numbers it’s likely a simple bug fix if anything notable.

Separately, Mac beta testers will find OS X 10.11.2 beta 4 also available to download and install.

How to Change 3D Touch Pressure Sensitivity on iPhone 6S


The new iPhone 3D Touch display detects the level of pressure placed on the screen and, depending on the app, action, or home screen icon, offers different responses and interactions. These “peak” and “pop” features are throughout iOS and offer shortcuts of sorts to perform various functions, and they’re really a great feature of the iPhone 6S lineup. Using 3D Touch takes a little bit of practice, particularly in regard to applying the correct amount of screen pressure to get the intended action, but one way to greatly improve the 3D Touch experience is to manually adjust the touch screen pressure sensitivity required to activate the various features.

iPhone users can easily change the amount of screen pressure required to activate 3D Touch, but because the setting is going to be unique to each person and how they use the feature, you’ll want to test out the various levels of pressure required with the handy adjustment ‘sensitivity test’ area to determine if the settings are appropriate for your needs.

How to Adjust 3D Touch Screen Pressure Sensitivity


This obviously requires an iPhone with a 3D Touch display, whether that’s an iPhone 6s or iPhone 6s Plus, other models will not have this setting available:
  1. Open the Settings app in iOS and go to “General” then to “Accessibility”
  2. Go to “3D Touch” and locate the “3D Touch Sensitivity” portion of the settings, the slider below this is what you’ll want to change to fit your preferences, pick one of the following:
  • Light – a soft amount of screen pressure activates 3D Touch peak, and a slightly more firm amount of pressure activates 3D Touch pop
  • Medium – the default level of pressure sensitivity for 3D Touch displays
  • Firm – a notably harder amount of screen pressure is required to activate 3D Touch peak and pop

    3. Next scroll down to the “3D Touch Sensitivity Test” area and press at varying degrees on the      
        image, the initial 3D Touch press will ‘peak’ on the image, and a harder press will ‘pop’ the        
        image

    4. When satisfied, leave Settings as usual and try the effect elsewhere in iOS


If you find yourself activating 3D Touch when you don’t always want to, you’ll probably want to use the “Firm” option, whereas if you find the required pressure is too great, using the “Light” feature is ideal.

This is really largely a matter of personal preference, but it also depends on what you’re using to activate the touch screen, if you use a case on the iPhone, and your general usage patterns, and whether or not you use a finger, toe, stylus, or other pointing device.

My personal preference is for the “Light” setting but when demonstrating the feature to a friend they found it way too easy to activate, so they strongly preferred the Firm setting. Try it out yourself and see what works for you, you can always make another change again by returning to 3D Touch settings.

How to Check Stores for Apple Pay Support from iPhone & Mac


Apple Pay is undeniably convenient, allowing you to make quick and secure purchases right from your iOS devices. So, you setup Apple Pay on your iPhone and on the Apple Watch and now you want to put it to use, right?

While many popular stores are known to support Apple Pay, there is no reason to be stuck wondering if a particular location, store, or shop supports Apple Pay purchases, because you can actually check for Apple Pay compatibility at most retail locations by using the Maps application.

How to Check Retail Store Locations for Apple Pay Support from iOS


This is a really easy trick, it’s just a matter of looking in the right place of a maps listing. In this example here, let’s pretend we want to spend an entire paycheck at Whole Foods buying a few organic vegetables:
  1. Open the iOS Maps application on the iPhone (or iPad or iPod touch, but iPhone is most useful since you’ll likely be on the go when using this)
  2. Search for the store or shop you wish to check Apple Pay support for
  3. Tap on the listing when it appears in the Maps app, then scroll down to find the “Category” and “Price” section, alongside that information you will see an “ Pay” Apple Pay indicator if that specific store or retail location supports Apple Pay for payments


Simple and easy. These listings are updated often in Maps so if a store doesn’t currently support Apple Pay but later adds the ability, it should make an appearance rather quickly.

Check Store Locations for Apple Pay Support from Mac OS X


Equally as simple is to check for Apple Pay support for any store location from the Maps app in Mac OS X:
  1. Open Maps and search for the store you wish to check Apple Pay support for, then click on the listing info button (i)
  2. Look for the  Pay indicator, if it exists, it means the store supports Apple Pay

Many popular stores support the Apple Pay payment service, but it’s still nice to be able to check beforehand. Now you can determine ahead of time if a store supports Apple Pay so that you can make payments with your iPhone or Apple Watch, or if you’ll have to bring along a credit card or that funny paper stuff known as cash to make a purchase.
