[Samsung Galaxy A21s Questions & Answers] Nazo:
Honestly, between context and etc I'd say it's pretty clear which it means with zero ambiguity. As for separate threads, they basically do already exist. Removing the Samsung "factory reset protection" (FRP) is fairly generic across multiple devices and, excluding perhaps device-specific exploits, really has already been pretty fully covered countless times all over the Internet (just google it.) Carrier unlocking is tricky (it's only legal after a certain minimum time) and typically you're supposed to go through the carrier themselves to get them to unlock it is my understanding. Getting a carrier unlock is tricky and, depending on the circumstances, isn't even always legal (has to be past a certain time period I believe? Doing it manually may be illegal if before that time period even if it doesn't get the SIM dirty flagged.) This too isn't really device specific except in regards to how one specific device could maybe be exploited to break it. Of note, anything specifically illegal wouldn't be allowed here anyway. I don't even think anyone would create device-specific threads for the other supposedly common uses -- those are generally more of a use case scenario (eg how do I fix MY phone, not how do I fix device model so-and-so. Such uses need their own individual threads typically.) What's more, while I don't think anyone ever calls rooting a device "unlocking" it (we all call it rooting and that has been the accepted term for probably about as long as Android has existed,) the two basically go hand-in-hand since a bootloader unlocked phone can just use Magisk or similar these days (assuming you can't just directly adb a su binary or something -- yes I've seen some with writable system partitions. A bootloader unlock basically guarantees easy rooting.) All in all I'd say that's all pretty well covered about as well as it can be elsewhere and really is just a matter of googling or creating individual threads as needed and just does not apply here. The fact is, they were arguing semantics to a level that even I, the person who drives everyone around him mad with semantics, would never go so far as to push. Context is a thing that even I respect.

Right now I'm a bit more concerned about the recent major exploit in Samsung modems though. I never could get a clear answer on if this truly even affects the A21. All the security warnings on various sites say A21 in their list, but that may only mean the A21s as the SoC itself in the A21 (as we know all too well) is a generic MediaTek, not an Exynos. However, it's not impossible that Samsung could have provided the modem itself -- at least in theory. I'm not sure of any way to find out. This is honestly an even bigger reason I'd like to see full unlocking, rooting, and etc, as it would give us more control over these devices. I am, honestly, afraid even to use my A21 because VoLTE can't be turned off or controlled directly on it so, if it is vulnerable to the exploit it could be easily attacked at any time (no need for a hacker to do so directly even -- they could utilize a bot to automatically run down lists of numbers or even just pick numbers at random.) Presuming this means driver-level access, it's presumably basically almost root for purposes of what such a hacker could actually do with it (bit of irony they'd basically have at or at least close to root access to our devices and yet we still don't.) My own phone denies me access to things like manual control of the VoLTE flag. Ironically I'd like to see this rooted all the more, if nothing else, because I'd have more control over such things. However, I'm hoping to replace mine soon with a Qualcomm-based Pixel device anyway, so I hope to leave all this behind. (Well, my A21 could possibly be dedicated to some other purpose or just become an emergency device, but I can presumably put aside worries about an exploit coming through phone services if it has no SIM anyway.) IF these issues do apply to the actual A21 and not only the A21s though, this thread perhaps becomes all the more important as I see carriers like mine so far behind it's actually scary. (I just got a December security patch about two days ago. DECEMBER...)

I guess A21 users should keep an eye out one way or the other.
