Sorry for the trouble this has caused you. The POCO X7 Pro has passed rigorous reliability tests, including drop, roller, and micro-drop tests, and the side button pull-out force meets the test standards. Therefore, the side button design meets normal usage requirements under typical conditions. However, if you're using a protective case made of very hard material, it will cause added pressure on the buttons, potentially loosening them over time. In such cases, it is recommended to assemble the side button position first, and then assemble the other side.
