Question about OPPO A94

Yes, Oppo was not affected by the US sanctions. Only the newer Huawei devices, which came onto the market after the US sanctions came into force, do not have a Google Play Store.

A good alternative to an Oppo might be the Xiaomi Mi 11 Lite, maybe that's a good choice too? It also has 8GB of RAM and 5G. It has a massively better processor than the Oppo A94 (the Mi 11 Lite is almost twice as fast and the CPU is made with more power efficient 5nm, the Oppo is 7nm).

Xiaomi Mi 11 Lite 5G (8GB) (128 GB, Truffle Black, 6.55 ", Dual SIM, 64 Mpx, 5G)
