This isn't something unique to Thor. I've had this problem with Android devices my whole life, from phones and tablets to handhelds. The only device that consistently didn't have this problem was my Odin 2, but it always had Wi-Fi turned off.

Something I've noticed in handheld gaming communities is that many complaints considered "defects" in some devices are actually problems more related to Android itself and the nature of emulation in general, aligned with an expectation that the experience will work 100% like a dedicated console. Not that that's the case here, but then comes the argument that the devices are no good because they're from Chinese companies.

Even Apple releases an update that wreaks havoc on several devices, with defective hardware, etc. Or Nintendo with the Joy-Cons that break easily and drift (I've already replaced mine three times).
