I do remember a product recall which happened for specific Roav Dashcam C1, identified based on specific set of product serial numbers
It is normal for a battery to expand in higher temperatures and designs usually are made to accommodate what the industry refers to as “swelling.” In earlier Roav Dashcam C1 products, there wasn’t enough room in the design to accommodate for extreme heat expansion causing the screen to bulge out. Newer versions were trying to have fixed this issue. Not sure if this recall extended to C1 Pro as well.
These Dashcams come with 24 month warranty, so the right thing to do is to contact Roav Support and they would replace it as long as warranty covers it.
