Samsung’s Auto Hot-Spot Feature

I own a Samsung Galaxy S9 smart-phone, and have discovered that, in its tethering settings, there is a new setting, which is named “Auto Hotspot”. What this setting aims to do if activated is, on other Samsung devices, which normally only have WiFi, when the user is roaming along with his phone, there should appear an additional access point for them to connect to. The following screen-shots show, where this can be enabled on the phone

I believe that this explains a fact which I’ve already commented on elsewhere, which is, that when I try to set up Google Instant Tethering, the negotiation between my ‘Asus Flip C213 Chromebook’ and this phone, no longer adds Instant Tethering to the list of features which are enabled. My Samsung S9 phone will now only unlock the Chromebook. What I am guessing is that, because the feature I’m showing in this posting is a Samsung feature, with which Samsung wants to compete with the other companies, Samsung probably removed to offer Instant Tethering from their phone.

Obviously, this is only a feature which I will now be able to use, between my S9 phone, and my Samsung Galaxy TAB S6 tablet.


 

 

The reader may ask what the advantages of this feature might be, over ‘regular WiFi tethering’, or ‘a WiFi hotspot’. The advantage could be, that even though it remains an option compatible with all clients, to have the phone constantly offer a WiFi hot-spot could drain the battery more. Supposedly, if Samsung’s Auto Hotspot is being used, it can be kept enabled on the phone, yet not drain the battery overly, as long as client devices do not connect. The decision could then be made directly from the client device, whether to connect or not… This is similar, to what Google’s system offers.

Also, the Samsung phones with Android 10 have as feature, that their ‘regular hotspots’ will time out, say after 20 minutes of inactivity, again, to save battery drain. Yet, if the user is carrying a tablet with him that has been configured to connect to the mobile hotspot Automatically, the phone which is serving out this hotspot will never detect inactivity.


 

Further, I’ve been able to confirm that, as long as I have Auto Hotspot turned on on my phone, indeed it does not show up as an available WiFi connection, on devices that are not joined to my Samsung account. This is as expected. But it also adds hope that, as long as I don’t connect to the phone’s Auto Hotspot from another device, the battery drain due to my leaving this feature enabled on my phone constantly, may not be very high. I will comment by the end of this day, after having left my phone with its own WiFi Off, which means that my phone will be using its Mobile Data, but, not connecting my Samsung TAB S6, whether doing this seems to incur any unusually high amount of battery drain, on the phone…

USB C Cables / Connectors

The subject may already be familiar to many other people, that there now exists ‘a type of USB connector / plug / jack, with which they do not need to worry, in which direction it’s facing, when they plug it in to a compatible port’. The type of connector I’m referring to is a USB-C connector, which brings with it, USB-C cables, that connect from a Type-A to a Type-C jack.

One fact which I should point out is that even though we live in a relatively modern time, in which we might think that companies can do anything, If it’s also a requirement that they’re supposed to mass-produce equipment cheaply, they can no longer just do anything. The tolerances for a Type-C USB jack are quite small, and manufacturing machines themselves have limits to their precision.

One experience I seem to have made not once but twice, is that when I purchased USB-C cables that were visibly meant for Apple products, they did not seem to snap in to my ‘Google Pixel C’ tablet snugly, the latter of which could also be seen as a kind of Samsung-like, Android product, in direct competition with Apple. I needed to repurchase each time, and then for made-for-Samsung jacks, before those would seem to have a satisfactory fit into my Pixel C.

If we’re forearmed with this observation, we can make sure either to buy USB-C cables made for Apple, or, cables made for Samsung, since there are many suppliers of cables.

I suppose that a more-nefarious question which some people might have could be: “Did Apple deliberately change their USB-C ports, to make those incompatible with the Android-related ports?’ But my guess at an answer to that question would be ‘No.’

Why AirDroid holds promise for me, after all.

There exists a higher-quality solution to this need, known as ‘Samsung Side-Sync’. But a big problem in my own desire to use this Android app, is the fact that its client-program is only available for Mac or Windows – while I mainly tend to have Linux installed on my PCs and laptops.

The capability which the app delivers, is to turn the Android device into a type of remote, VNC Host, or Server, on which a client seeks to establish a session, in which the properties and resources of the host, are displayed on the client-computer, remotely, as if the user of the client was in fact sitting in front of the host.

This is not so strange an idea, as various types of VNC / RDP already exist, by which a remote session is created on a Windows or a Linux PC as host, such that the client – even if that client exists as an Android client – can seem to have a remote session.

Because I was intrigued by making the Android device the host for a change, and by the possibility of using a Web-interface as client, I decided to give an app a try, which is called AirDroid. After all, even Linux computers have Web-browsers which would be powerful enough to run as clients.

I installed the app on my up-to-date Google Pixel C Tablet, But was initially disappointed, in the apparent observation, that AirDroid just did not seem stable enough to trust with such an objective.
