How NFC blocking worked
A software update that slips unnoticed in the background can disrupt your most basic digital habit. That's exactly what happened to those carrying smartphones purchased directly from the Asian market, according to data collected by Notebookcheck.
The mechanism was automatically activated when the phone approached a POS terminal, reading the software's characteristics. As developer MarvinFS explained in a post on XDA Developers , the Play Services code in version 26.28 recognized Chinese SKUs and instructed the TapAndPay HCE service to be disabled. Google Wallet appeared to be working perfectly on the screen, but transactions failed miserably at the checkout.
The devices found in the eye of the cyclone
The bug did not discriminate between manufacturers, as long as the device was running the factory Chinese firmware. The list included flagships such as the Vivo X300 Pro, X200 Ultra, the foldable X Fold5, as well as devices from Oppo and OnePlus.
If you had purchased the corresponding Global version in the Greek market, you would be completely exempt from the problem. However, for import enthusiasts who prefer Chinese versions for better prices or early release, the sudden discontinuation of Google Pay created a huge headache.
Temporary solutions and workarounds
Before Google could patch the backend, users were forced to improvise to make payments. The most popular solution suggested by the community, such as user “Just_Soul” on XDA , was to opt out of any Play Store beta programs.
Other users turned to alternative digital wallets like Curve Pay, while the more experienced attempted to downgrade Play Services via ADB. Fortunately, Google put an end to the hassle by restoring the functionality remotely.
Our opinion at TechNoid
We at TechNoid believe that this “bug” was not a coincidence at all, but a test of the device restriction infrastructure. Google now has the tools to selectively block hardware based on the region of origin of the ROM, and this is a serious concern for us. If you are thinking of buying a Chinese version of the phone to save money, remember that digital services may be cut off again completely arbitrarily.
