Android is getting a new ‘Instant hotspot’ feature that should make it more seamless to connect an Android tablet or Chromebook to your phone’s data connection. However, Samsung devices won’t get the feature.

Instant hotspot will roll out as part of the recent Android feature drop and will allow people to easily and quickly share their Android phone’s hotspot with tablets or Chromebooks. The feature will save people time by skipping steps like turning on the hotspot on your phone or entering a password on your Wi-Fi-only device.

However, Android Authority spotted fine print on an image of the feature saying it’s “not available on Samsung devices.” It’s not immediately clear why, but the publication speculates Samsung might have opted out of Instant hotspot since it already offers its own version of the feature, but exclusively for Samsung phones and tablets.

Samsung’s hotspot feature, coupled with the fact that Chromebooks already have an ‘Instant Tether’ feature for easily connecting to a phone’s hotspot, means not getting Instant hotspot won’t be a huge loss for Samsung users.

Still, it’s a bit odd that the feature isn’t coming to Samsung devices since it’s part of Google Play Services, which is available on all Android devices certified by Google.

Pixel owners know about feature drops, because they are Google’s way of continuously adding value to devices. With each big quarterly update, Google tosses out new software ideas onto Pixel phones and tablets to keep things fun and fresh. For those who don’t follow closely, Google does this for the Android platform too. We get regular Android feature drops for Samsung, OnePlus and other Android devices, just like we’re about to talk about below.

In this latest Android Feature Drop, Google is adding improvements to Google Messages (editing!), Google Home, and Wear OS, while bringing new features like digital car keys, more Emoji Kitchen combos, and the ability to instant hotspot to Chromebooks.

GOOGLE MESSAGES EDITING: That’s right, you can now edit a message you’ve sent in Google Messages. Google is rolling this feature out and will give users a 15-minute window to edit group or one-on-one messages once they have been sent. To do so, you’ll long-press on a message and then tap the little pencil/edit button up top to adjust your words. This only works with RCS messages.

GOOGLE HOME FAVORITES WIDGET: The Google Home app is getting a fun new Favorites Widget that can be added to home screens. This widget lets you do everything from changing temperatures to viewing doorbells and adjusting lighting. The widget is also advanced enough that it can be resized to various shapes to show additional favorites if you have more than a couple.

To get access to this new Favorites widget, Google says that you need to be signed-up for the Public Preview of the Google Home app. You can sign-up here.

INSTANT HOTSPOTS, CALL SWITCHING: Coming soon, you’ll be able to connect to an instant hotspot from your phone to your Android tablet or Chromebook. That’s cool and all, but Google is also going to let you seamlessly transfer Google Meet calls between phones and tablets by pressing the Cast button.

Google appears to be setting this feature up through a Devices & Sharing area in your phone’s settings that will have an option called “Cross-device services.” Within this area, you’ll be able to choose the devices you want to group together and can then decide if they should share call casting and internet sharing.

GOOGLE HOME ON WEAR OS: Beyond the new Favorites widget for your phone’s home screen, Google is also rolling out a Favorites Tile for Wear OS that allows you to easily adjust your smart home devices from the wrist. Like the widget, you can customize the shortcuts on this tile.

WEAR OS GETS PAYPAL: Speaking of wrists, Google Wallet on Wear OS can now make payments with PayPal in the US and Germany.

EMOJI KITCHEN EXPANDS: Emoji Kitchen, which is Google’s silly emoji mash-up tool, has added new combos that involve the disco ball and headphones.

MORE DIGITAL CAR KEYS: Finally, Google is rolling out digital car key support to more vehicles, starting with select MINI models. They plan to further expand “soon” to select Mercedes and Polestar vehicles too. We’ll try to get a list of the cars for you.

Some decent stuff in there, right?

Samsung is continuing its trend to move away from the overly round hardware design aesthetic. We saw it with the Galaxy S23 Ultra into the Galaxy S24 Ultra and now it appears that we’re going to see it on the Galaxy Z Fold 5 into the Galaxy Z Fold 6.

The image above is the first supposed real look we’ve had of the device. Before this, we have seen only 3rd-party renders. Thankfully, the Z Fold 6 photo is alongside a separate photo of the Z Fold 5, allowing us to see the major difference in design from the frontside.

We can see that the Z Fold 6 is much more squared off, especially at the hinge compared to last year’s model. The bezels, while still noticeable, are certainly a bit smaller. The overall size of the hinge has also seemed to go down considerably, making the device appear much more compact. In fact, I’d argue that the hinge becomes hardly noticeable with this improved design. For those who carry this device in a front pocket instead of a purse, satchel or crossbody bag, this is welcomed news.

We’re expecting this device to be detailed in full in Paris this July ahead of the Olympics, alongside the Z Flip 6, Galaxy Ring, and lineup of new Galaxy Watch 7 models. It’s going to be a most excellent 2H for Samsung fans.

Thoughts on this device and Samsung’s new squared design?

This guide intends to teach you to Create a Sudo User on Ubuntu 24.04 From Terminal. In Ubuntu 24.04, a sudo user is a regular user who has access to administrative privileges for running commands with root privileges. This can be done by running commands with sudo, “superuser do.” You can use sudo for many tasks, such as installing software, modifying system configurations, and managing users, without logging in as the root user.

Here are some tasks you can do with a sudo user on Ubuntu 24.04:

Get Admin Points: A sudo user can temporarily get root privileges to run commands that need higher permissions.Security: Using sudo reduces the security risks instead of using root users.Accountability: Sudo logs all commands executed with high-score privileges. It provides an audit trail for administrative actions.

Then, you can add your user to the sudoers for getting admin privileges. For this purpose, you can use the usermod command. This will help you to add your users to the sudoers group. The syntax command looks like this:

usermod -aG sudo username

For example, for adding the noble user to the sudoers, we can use the command below:

sudo usermod -aG sudo noble

Note: All users’ details are stored in a file named the /etc/passwd file. To verify that the user was created, you can view this file using the cat command or view more details with the id command:

# cat /etc/passwd | grep noble
# id noble

In your output, you will see:

Next, you can switch to your new user account from the terminal by using the following command:

su – noble

You must enter the user password and try to run the commands by using the sudo. For example, run the system update:

Note: It is recommended to consider the following practices for sudo user:

Only use sudo when necessary to reduce potential security risks.After completing admin tasks, log out of the sudo session to reduce the risk of accidental system changes.Regularly check the sudo logs in /var/log/auth.log to monitor the usage of sudo privileges.

Also, if you plan to remove the users, you can proceed to the next step.

Delete Users on Ubuntu 24.04

At this point, if you would like to delete and remove your user, you can use the following syntax:

deluser username

For example, to delete the noble user, we can execute the following command:

In this guide, you will learn a complete setup tutorial to Secure Ubuntu 24.04 with AppArmor. AppArmor which stands for Application Armor is a Linux Kernel security module. It is used to increase the security of the operating system by limiting the access that applications have to the system’s resources. Also, it uses profiles to define the restrictions for each application.

AppArmor acts in two modes which are:

Enforcement Mode: Actively enforces the restrictions defined in the profiles.Complain Mode: Logs policy violations without enforcing them. It is useful for testing and refining profiles.

Now follow the steps below to Secure Ubuntu 24.04 with AppArmor.

Easily Learn to Secure Ubuntu 24.04 with AppArmor

By default, AppArmor comes pre-installed on Ubuntu 24.04 and can be easily enabled and configured. You must log in to your Ubuntu 24.04 as a root or a non-root user with sudo privileges. To create a sudo user, you can check this guide on Create a Sudo User on Ubuntu 24.04 From Terminal.

Step 1 – Enabling and Checking AppArmor Status on Ubuntu 24.04

As we said, AppArmor is installed by default on Ubuntu 24.04 and must be enabled. To verify AppArmor is enabled, you can run the following command:

cat /sys/module/apparmor/parameters/enabled

In your output, you should get Y which means your AppArmor is enabled. But, if you don’t get the Y output, you can easily enable AppArmor using the Linux kernel command line in the bootloader. To do this, run the following commands:

# sudo mkdir -p /etc/default/grub.d

# echo ‘GRUB_CMDLINE_LINUX_DEFAULT=”$GRUB_CMDLINE_LINUX_DEFAULT apparmor=1 security=apparmor”‘
| sudo tee /etc/default/grub.d/apparmor.cfg

# sudo update-grub
# sudo reboot

At this point, you can check your current AppArmor profile status for each app on Ubuntu 24.04. To do this, run the following command:

sudo aa-status

In your output, you will see something similar to this:

As you can see from the output, 134 profiles are loaded and 45 profiles are in enforce mode.

Step 2 – Change AppArmor Profile Modes on Ubuntu 24.04

In this step of Secure Ubuntu 24.04 with AppArmor, if you plan to change your profile modes, you can easily follow the steps below.

To set your profile to complain mode, you can use the following command:

sudo aa-complain your-profile

For example, to set the /usr/bin/man profile to the complain mode, you can run the command below:

sudo aa-complain /usr/bin/man

To set your profile to enforce mode, you can easily use the following command:

sudo aa-enforce your-profile

For example, to set the /usr/bin/man profile to the enforce mode, you can run the command below:

sudo aa-enforce /usr/bin/man

Also, you can modify changes to all profiles. You can set all profiles to enforce or complain mode. To do this, you can use the following commands:

sudo aa-complain /etc/apparmor.d/* #complain-mode

sudo aa-enforce /etc/apparmor.d/* #enforce-mode

Note: If you get any command not found error with AppArmor commands, you must install the AppArmor Utils to fix it. To do this, run the following command:

sudo apt install apparmor-utilsStep 3 – How To Create a New Profile with AppArmor on Ubuntu 24.04?

In this step of setup to secure Ubuntu 24.04 with AppArmor, you will learn to create a new profile. First, you must find the applications that need security they haven’t any profile in AppArmor. For this purpose, you can run the following command:

sudo aa-unconfined

In your output, you will see something similar to this:

Once you find the applications that are not confined, you can use the following command to create a profile for them:

sudo aa-genprof unconfined-app

It will start to create your profile. During the process, press F to finish your setup. By default, it will created as the enforce mode. You can easily change the profile mode like the previous step.

Next, you must reload your AppArmor service to apply the changes:

sudo systemctl reload apparmor.service

At this point, you have learned to Secure Ubuntu 24.04 with AppArmor, let’s see how you can delete a profile and disable AppArmor.

Step 4 – Delete a Profile and Disable AppArmor on Ubuntu 24.04
