TECNO has officially unveiled the latest Spark 40 series, introducing four standout models: Spark 40, Spark 40 Pro, Spark 40 Pro+, and Spark 40C. The lineup showcases a trendy, ultra-slim design and is equipped with advanced features like AMOLED displays, fast charging capabilities, and AI-powered enhancements running on Android 15. Meanwhile, we at PassionateGeekz have exclusively discovered the existence of a fifth device in the series—Spark 40 Plus—which TECNO has yet to officially announce. Interestingly, the device briefly appeared on the FCC certification platform but has since been removed from the same. However, it remains accessible through TECNO’s partner sites, suggesting the possibility that the device has either been temporarily put on hold or potentially canceled.

We have spotted the TECNO Spark 40 Plus carrying the model number KM5s on the IMEI Database. While the listing does not disclose any specifications, it does confirm the device’s existence.
