Why is there black glue overflowing from the gap of the Xiaomi Smart Band 10?

The Xiaomi Smart Band 10 has been strictly inspected before leaving the factory. In particular scenarios or angles, you can see a slight overflow of glue in the gap of the band. This is because a small amount of waterproof glue is injected to ensure waterproof performance. It does not affect the normal use and waterproof performance of the band. Please feel free to use it.
For your reference, here are more details about the black glue overflowing from the gap of the device:
1. It is not recommended to use blades, nails, coins, etc. to scrape glue, as it can easily scratch the screen or glass cover;
2. Do not heat to soften or dissolve the glue by yourself (such as hair dryers, solvents), which can damage internal components or waterproof structures.
