Installation and precautions:
1. Wipe the back of the mobile phone and find the location of the earphone hole (some mobile phone charging hole is the earphone hole), which is the location of the main antenna of most mobile phones; if the effect is not good, paste the location of diversity antenna;
2. Tear off the white adhesive tape behind the signal sticker and stick it 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 can be solved by consulting customer service;
4. Be careful in the process of installation and use. Do not rub or damage by external force. Keep the signal paster clean. Do not touch the front of the chip directly by hand. The surface should not be stained with fingerprint dirt and sweat
5. The material and thickness of some mobile phone cases will have a little influence on the chip. Please wear the case for comparison. If there is no difference, install the case. It is recommended not to use the case.
