I discovered (to my slight surprise) that until November 2018, the FCC of the US of A didn't allow smartphones to use the European "Galileo" alternative to GPS: "American phones couldn’t use Galileo because the FCC has regulations against having ground stations being in contact with foreign satellites".
So picking up a signal, which is there, no matter what you do, is "being in contact with foreign satellites". Not a very intimate form of contact, I'd say!
You US of A guys: How is it nowadays? Do you have Galileo enabled smartphones? What about the Russian Glonass or the Chinese BeiDou? Or is US of A more or less ignoring anything but GPS?
(Bonus question: How many of you answer: "I never was aware of anything but GPS, but now that I check it, I see that I have Galileo as well!")

Apps like GPS Status display what birds they can see, often colour coded by constellation, or different map symbols. Right now, in my study, my phone can see 56 satellites with 5 different symbols. Labels include
### straight number, probably GPS
j### Japan?
e## Euro? (Galileo)
c## China?
r## Glonass?

For Android install this: GPSTest[^] - the "Status" page shows you which GNSS satellites you are using.
You may be able to find similar for Apple, but I don't know.

Note that the download page states support for "GPS (USA Navstar)" only, with not a word's mention of Galileo, Glonass or BeiDou. The page is updated in May, so I guess it is not because the information is outdated.
If it didn't say anything at all about GNSS system support, I'd think that it would show all those that the smartphone supports, but when GPS is mentioned explicitly (as the only one), I'd think that others are not supported.

For me it shows I'm using US NAVSTAR, Russian GLANASS, and Chinese BeiDou.
It also lists EU Galileo, Japanese QZSS, and Indian IRNSS, but doesn't seem to use them
That may be the Chinese chipset (it's a Huawei P30) doesn't support the Galileo L5 frequency, just the older L1.

Some years ago, there was a serious concern about putting all eggs into the GPS basket. Several countries (/groups) argued in favor of keeping alive some alternative navigation system, such as Loran-C in its modern enhanced form, eLoran, with a precision of 3-8 m (depending on who you ask).
Lots of people argue that there is no need for Loran: If GPS fails, we can use GLONASS. If that fails, too, there is Galileo. And BeiDou. And QZSS. And IRNSS. So all plans for eLoran deployment were canceled.
But all these systems have roughly the same failure modes, at least partially. A high-intensity magnetic storm could knock them all out. Then can all be deafened by noise transmitters in roughly the same frequency range. If a terrorist group have the means to e.g. shoot down the satellites of one of the systems, chances are that it may do the same to them all; they are quite similar.
I would relax a lot if we (re)established a backup navigation system based on a significantly different technology, with different failure modes. eLoran is probably the best candidate. It appears that funding fathers of today think one basket of eggs is enough. I do not like to think of the effects of a real geomagnetic blast. If we one day experience it, there will be a worldwide hunt for scapegoats who haven't provided any sort of alternate system. (If the storm is bad enough, it may knock out Loran as well, but the GNSS satellites are magnitudes more vulnerable!)

Always the way.
Way back in the 90's, Perrier was the top bottled water provider - if you drank mineral water anywhere in the world, 95% of it was Perrier.
Then they had a contamination problem (Benzene) and realised that they had no idea where the contaminated water was - they didn't code the bottles, case, or pallets at all so they couldn't identify the good ones from the bad ones. So they sat on it. Until a whistleblower dropped them in it, and they had to do a recall.
Of every single bottle of Perrier, world wide.
It took weeks to get clean supplies back into shops, and in the meantime people tried their local variants and wondered why they were paying so much for Perrier.
After the recall, they only got back up to 20% of the water market.
And nobody else coded either because it was deemed not vital to the business - but suddenly the board of directors wanted to know why they didn't, and what it was going to cost. They wrote some very big (and inflated) cheques, very quickly and started a massive boom in coding and marking (of everything!) which is still a huge business today.
Then in 2002 a Large British Biscuit manufacturer found that a flour filter had disintegrated on an hourly check. The line was stopped, the current batch was scrapped and because they coded and tracked every packet they turned round every lorry with a single biscuit that might have been contaminated on it. Not one reached a shop, let alone a customer.
That's the power of hindsight - money doesn't get spent until something goes wrong! Stupid, I know ...

I bought my current smartphone half a year before Galileo services was officially released to public use (and it was probably manufactured half a year before that). It has GPS support only, and not even a very precise one (accuracy typical 8-12 m). The raw phone doesn't have anything but an on-off switch for GPS, no other status info.
I am not familiar with newer models, so I can't tell how you check yours.

Edit - I misread your post and thought the question is about GPS receivers in general instead of smartphones specifically.
Not sure what is the source of your info, but considering that all professional grade GPS receivers (Trimble, Leica, Hemisphere, etc.) can receive all the navigation satellites out there, I very much doubt that there is such regulation or that it is enforced.

My quote was from TechCrunch[^], reference [187] in English Wikipedia: Galileo (satellite navigation)[^]. The Wikipedia article discusses the issue to some extent.
Apparently, there was such a regulation until November 2018. As the TechCrunch article discusses, enforcement was almost impossible. E.g. although most smartphone manufacturers for the US of A market disabled software support in phones that had hardware support, an app might unlock it. I have seen no indication of any such regulation being in effect as of today.
There are numerous examples of hardware support for some technology, not made available to the user. This may be due to national regulations (such as for Galileo pre 2018), or pure marketing: The manufacturer wants to reserve some functions for premium products, or to force the customer to buy a new product at a later time.
One example: When DAB digital radio was introduced in Europe, there were only a small handful of DAB chip makers. All of them made chips supporting DRM, the digital radio standard for "the AM bands", now a major broadcasting technology in India. Lots of DAB radios used those DRM capable chips - but provided no button or menu option to select this band! If all (/most) DAB receivers had given access to DRM, DRM might have been a reality in Europe as well, after a series of successful trial transmissions. Radio manufacturers hoped for a DRM success, so that they a few years later could sell new receivers to the the market (maybe they would use the same chips, but omit a selector for DAB!). With no consumer receivers on the market, no broadcaster went for DRM.
I wouldn't at all be surprised if Galileo was used for market manipulation in a similar way, in principle being available, but only to a selected group willing to pay a premium price for it.
What I really is concerned about is not smartphones in particular, but how vulnerable the US society is to a hypothetical complete GPS failure, e.g. as a result of a sabotage/terror action. One part is the civil society. Another question: Has USAF fallen down to the level of including a foreign GNSS system as a backup, in case their own GPS becomes unusable? This is all speculation, so to try to find some more tangible information, I asked about smartphones.
Here Norway/Europe, we are close to a state where we would hardly notice if every single GPS satellite was shot down tonight. (My late winter/spring 2016 smartphone is like a museum artifact that doesn't count for this purpose.) I sort of suspect that the US of A society might be harder hit. I ask because I am not sure about that.

This is all speculation, so to try to find some more tangible information, I asked about smartphones. Let me tell you a story from the early '90es, also the early GPS years:
The initial GPS system was designed with a feature called "selective availability" (SA) that could degrade the civilian signal to about 100m, if I recall correctly. When the first Gulf War started in '91 we were all expecting the SA to be turned on and wondering how we will cope with the reduced accuracy. It turned out that not only Air Force didn't turn SA on, they even did the utmost to have the ephemerides as accurate as possible. It turned out the US forces didn't have enough military grade GPS receivers that could be used to decode the military P-code and had to use commercial grade GPS receivers. It took however another 10 years or so until Clinton administration finally finally killed the SA "feature".
Obviously I don't know anything about the plans and the readiness state of US military, but past examples don't show them as being infallible planners.
What I can tell you that the vast majority of professional GPS units used in Canada for land and marine surveying are 2 (GPS and GLONASS) or more systems. Newer receivers that I've seen are 4-system units (GPS, GLONASS, Galileo, Baidu) with 30 or more channels. Some units go up to hundreds of receiver channels. Here, in Canada, having GLONASS is seen as a desirable feature as it operates better in high latitudes.
Given that no one makes products specifically for Canadian market, the same applies for US market.
