insta360 x3 lens replacement repair

I scratched the back lens of my Insta360 X3 after dropping it. Insta Care was costing me about £150 and I had to send Insta 360 to Hong Kong as there isn&any repair centre in the Eu/UK. after digging and doing some research I decided to take the risk by myself. So I bought the len from AliExpress and a set of phone opening toolkits.. & fixed it by myself Watch till the end for the result... and quite happy with the result there is 5% difference which is hardly noticeable
