I was faced with the same question and when I bought the Poco X6 Pro, I actually wanted the yellow one because of the vegan leather back cover. But that cost 409, while the black one was 349. So I bought the cheapest one with 512 GB memory.
Today the yellow phone is 321.
It's always the same phones, but the retailers behind the Digitec offers change or adjust the prices dynamically. Digitec couldn't explain to me why the 512 GB versions are cheaper than the 256 GB versions, I got different retailers as an answer. It apparently doesn't matter that one with 512 GB is much cheaper, so it's perfectly clear that I would never buy less memory for more money.
The yellow Poco X6 Pro is generally the most expensive model of the three colour variants, but when it's available for just 321, go for it. The case supplied is dark grey and if you don't always want to show off your yellow Poco X6 Pro, you can easily take this version, if you want to use it without a case, the vegan leather is not a fingerprint magnet. Another advantage.
The memory is not expandable. Thank you for letting us know. We will be happy to pass this on internally to the responsible department and hope that this will be adjusted promptly.
Do not think so. "memory suport card: no". Should be nm card instead of no/microsd and only "select Huawei" phones. Improve graphics? I'm curious how this should work (usb4 protocol via SIM contacts and a GPU in a SIM format card? 🤭)
Yes, I know, I asked myself the same question and ordered the cheaper one after a short search. Everything is tiptop, updates made, super satisfied, also works great abroad, I'm currently in Africa, taking pictures until I drop thanks to the large integrated memory...
