Why is my NUISK MZXJ-4K 4K Thumb Action Camera not powering on past the logo, even after being fully charged?

Based on the provided manual for the NUISK MZXJ-4K 4K Thumb Action Camera, the troubleshooting section primarily addresses issues where the camera does not power on at all due to a low battery. However, your situation describes the camera getting stuck on the logo after being fully charged, which suggests a different kind of issue. Since the manual does not specifically cover a scenario where the camera is stuck on the logo screen, here are some general troubleshooting steps you can try: Perform a Hard Reset: If there's a reset button (often a small pinhole), try pressing it with a paperclip. If not, try holding down the power button for an extended period (e.g., 10-15 seconds) to see if it forces a full power cycle. Remove and Reinsert SD Card: A corrupted or faulty SD card can sometimes prevent devices from booting correctly. Try removing the 128GB Micro SD card and then attempt to power on the camera. If it boots without the card, the SD card might be the problem. Try a Different Charger/Cable: Although you mentioned it's fully charged, sometimes a faulty charger or cable can lead to unstable power delivery, even if it indicates a full charge. Try using a different USB Type-C cable and a different compatible USB power adapter. Contact NUISK Support: Since the camera is new and you've already charged it, this could indicate a manufacturing defect or a more complex internal issue. The manual states, "For warranty information and technical support, please refer to the contact details provided on the product packaging or visit the official NUISK website. Our 24/7 support team is available to assist with any inquiries." This would be the most direct way to resolve the problem.
