How can I clean the dust and oil stains on my mobile phone?
The accumulation of dust will also affect the current conduction between the circuit board contacts. Grease: If the mobile phone panel is used for long-term veneering, the grease on the face may penetrate into the body, contaminate the internal circuit, and cause damage! Countermeasures: Clean the fuselage frequently. Or add a phone case and use a dust plug.
