Mobile phone Repairs Overview
Mobile phones are a little more difficult to get parts in order to replace or upgrade them. This is because the parts are smaller and a bit different due to manufacturers keeping the phones light, portable, and maintaining speeds equal to laptops. Mobile cell phone repairs require more attention to detail because there are so many screws, much smaller screws, and so little space in which to work. Be patient.
The following is a good list of items to remember when disassembling and reconnecting everything in a Mobile phone.
Use proper anti-static procedures. In mobile phone there are not always good places to attach an anti-static wrist strap. Consider using anti-static gloves. Maintain skin contact when touching parts if no other anti-static tools are used. This is known as self-grounding.
Organize your parts. Use a container or an egg carton and label individual sections with screws of like length and type and where the screws came from. Otherwise, use tape sticky side up to place like screws on and make notes to go with them.
Use appropriate tools. Scribes are very handy when removing plastic pieces A #1 Phillips screwdriver is a must.
Always refer to the manufacturer’s directions when removing and installing parts. Having a tablet or phone where you can pull this document up while you work is fine.
Note: Use your resources. No person can know all models of all machines they work on.
