How to replace the physical buttons

You should take your phone to a local repair shop or consult teardown guides on communities like iFixit before attempting a complex internal repair.

Why DIY is Hard on the LG Stylo 6

• Glued Back Cover: The LG Stylo 6 requires heat (from a heat gun or hairdryer) to soften the adhesive holding the rear glass panel before you can even open the phone.
• Internal Placement: The physical exterior buttons on modern smartphones are usually held in place from the inside by the midframe or require removing internal components (like the battery or motherboard) to install correctly.
• Risk of Damage: Slipping with a pry tool can crack the back glass or sever fragile internal flex cables.

Your Options

• Professional Help: Bring your phone and the replacement buttons to a local repair technician or check an upfront service like Stylo 6 Volume Keys / Power Button Replacement Repair to have a professional install them safely.
• Watch a Teardown: If you still want to try it yourself, look up specific video teardowns for the LG Stylo 6 to see if the buttons can be slotted in from the outside or if full disassembly is required.
