I didn’t say I consider either trustworthy/untrustworthy.
It’s just that I don’t trust the devices enough to keep working (or even do so well) to basically waive my warranty (by purchasing it from wherever they sell it).

Otherwise, it seems Unihertz has a better record (I didn’t find mentions of embedded malware) than Ulefone.

If I can buy it here, I have 14 days to return it. When I was choosing a phone, and employee of the store just told me to buy all of which I am interested in, test them, keep 1, return the rest. So I bought 3 phones and returned 2.
Not something I could do if importing a device.
