Google I/O: Android Q aims to bring app permissions firmly under control

Google is capitalizing on Google I/O 2019 to detail how it intends to make Android app permissions and security better in Android Q, which will, in turn, make your smartphone a safer, more secure place for your data.

The biggest change to Android Q’s permissions is the addition of a more targeted system. At the moment, granting a permission in Android is an analog process — you either grant an app storage permission or you don’t. While that makes everything nice and simple, it means that there are no limits on the app where timing is concerned.

In Android Q, you’ll be able to specify that you only want to grant an app permission to access your location data while you’re using that specific app. This means a chat app will no longer be able to access your location data while it’s not being used, but you’ll still be able to send your location to your friend when you need to.

Adding new options to permissions is only the beginning. Google is also asking app developers to find ways around permissions if they don’t need to be used — for instance, by using “Retreiver APIs” to pull relevant data, instead of granting blanket permissions that make users suspicious. Google highlighted how SMS Retrieval APIs can be used to confirm text message confirmation codes without the need to ask for SMS permissions.

There are times when permissions are absolutely required, and Google is also asking developers to make the reasons behind permissions more apparent. Only 18% of Android users allow apps all the permissions they request, and the top reason for denial is that the “app shouldn’t need the permission.” In those cases, it’s on the app developer to explain why it is their app needs these permissions.

Android Q will also be locking down some of your device’s individual indentifiers, including the IMEI, ESN, Build, SIM, and USB numbers. These hardware identifiers used to be available through certain permissions. An Android Q device’s MAC address is also completely randomized when connecting to a different network. Changing the way these elements of Android work significantly boosts user security.

These are my 8 favorite charity apps for iPhone and Android

Best charity giving apps.

Donating to charity is a great way to make a positive impact, and it doesn't have to be limited to just the holiday season. You can donate throughout the year, but finding the right organization can be challenging. Fortunately, there are many apps available to help you with this.

No matter what type of smartphone you have, whether it's an iPhone 15 Pro, Samsung Galaxy S23, Google Pixel 8 Pro, or any other mobile device, various apps can assist you in selecting the right charity to support those in need. Better still, some of the apps don't even want to collect your money. Instead, they want you to exercise or walk your dog for charity, give blood, and more.

Sunbird — the sketchy iMessage for Android app — just shut down

Sunbird messages app for Android

What was supposed to be an iMessage redeemer for Android smartphone users has quickly been consumed in a chaos of security and utter negligence. Merely days after the Nothing Chats app was removed from the Play Store, the tech at its foundation provided by Sunbird is also taking an unspecified leave, intensifying suspicions of something being seriously wrong.

Sunbird appeared on our radar late last year, promising blue bubbles for Android-to-iPhone messages. It also promised to bundle all messaging apps into a single cluster, somewhat like Beeper. Nothing adopted the Sunbird tech, bundled it into its own app for the Nothing Phone 2, and launched it with an ambitious video. “Sorry, Tim.” That’s the message Nothing CEO Carl Pei sent.

One of our favorite Android phones just got its own iMessage app

Nothing Chats app on a. phone.

Nothing is trying to bridge the great blue/green bubble divide for Android users of iMessage. This is not a personal crusade to shatter walls and open windows, as much as Nothing CEO Carl Pei would want you to believe that. Instead, Nothing is piggybacking on tech created by New York-based startup Sunbird.
Technically, the Sunbird app can be installed on any Android phone and it features a blue bubble for all iMessage text exchanges involving an Android phone. No more green bubble shame that could get you kicked out of groups for disrupting the harmony or even slim your dating chances. That’s how bad it is!
Nothing is adopting the Sunbird tech and bundling it as its very own app under the name Nothing Chats. But here’s the fun part. The app only works on the Nothing Phone 2 and not the Nothing Phone 1. And this life-altering boon will only be bestowed upon users in the U.S., Canada, the U.K., or the EU bloc.

The app is currently in the beta phase, which means some iMessage features will be broken or absent. Once the app is downloaded on your Nothing Phone 2, you can create a new account or sign up with your Apple ID to get going with blue bubble texts.
Just in case you’re concerned, all messages will be end-to-end encrypted, and the app doesn’t collect any personal information, such as the users’ geographic location or the texts exchanged. Right now, Sunbird and Nothing have not detailed the iMessage features and those that are broken.
We made iMessage for Android...
The Washington Post tried an early version of the Nothing Chats app and notes that the blue bubble system works just fine. Texts between an Android device and an iPhone are neatly arranged in a thread, and multimedia exchange is also allowed at full quality.
However, message editing is apparently not available, and a double-tap gesture for responding with a quick emoji doesn’t work either. We don’t know when these features will be added. Nothing's Sunbird-based app will expand to other territories soon.
Sunbird, however, offers a handful of other tricks aside from serving the iMessage blue bubble on Android. It also brings all your other messaging apps, such as WhatsApp and Instagram, in one place. This isn’t an original formula, as Beeper offers the same convenience.
