Pretty much the same as Nokia 5.3, but a few tweaks. Processor knocked down a rung, but more or less the same SoC. 4GB ram. Android One, so should get regular updates - 2 years of software, 3 years of monthly security. 24 months warranty. Midnight Sun (Orange) color only. Overall, not great, not terrible.
Edit: At its normal price of around $329, the Nokia 5.4 is easy to look past, but the value at $169 is hard to ignore. Versus similar tier phones such as the Vivo Y20 and Oppo A53 (both around $250 at JB), it does have the most powerful SoC (WiFi is not as good, however ) and software update guarantees.
