The Elevating Front Camera of V15 Pro has been rigorously tested before released to the public:

1. It moves continuously for 300000 times without faults(If you take selfies 100 times a day, it can work without fault for 8 years - 6 times more than NEX).

2. It is able to withstand 15KG of external force, which is tested by thousands of tests and experiments. It won`t break even if you try to press it with hard force(Note: We don`t recommend).

It has the most reliable elevation/retraction structure that other phones cannot achieve. You can use it with confidence.
