Tear off the white adhesive tape behind the signal sticker and stick vertically on the back of the mobile phone, with English letters and arrow end facing up (if there is a film on the back of the mobile phone, it needs to be torn, otherwise there is no effect); 3. Restart the mobile phone after pasting, most of the mobile phones will have direct effect, and a small number of mobile phones will have the situation of weakening the mobile phone signal for a period of time, which is a normal phenomenon. This is the identification and matching stage of some mobile phone antennas for the signal stickers. You need to wait for 24 hours to see the effect. If the effect is not good, try to restart it several times or adjust the position of the whole paste. 4. Be careful in the process of installation and use. Do not rub or damage by external force.
