As of my last knowledge update in January 2022, there was no information available about a Samsung Galaxy A14 5G model with 8GB RAM and 128GB storage. It's possible that this model has been released or updated since then. For the most accurate and up-to-date information, I recommend checking Samsung's official website or contacting an authorized Samsung retailer. They will provide the latest specifications, features, and any other relevant details about the Samsung Galaxy A14 5G (8/128GB) smartphone.
