1. The principle of mobile phone signal stickers is to increase the signal receiving range by lengthening the wavelength of the signal received by the built-in antenna of the mobile phone
2. Wipe the back of the phone clean and find the position of the earphone jack of the mobile phone (some mobile phone charging holes are the earphone jack), that is the position of the main antenna of most mobile phones, if the effect is not good, please change the position of the diversity antenna (refer to the picture )
3. Tear off the white adhesive paper behind the signal sticker and stick it vertically on the back of the phone, with the English letters and the arrow end facing upwards (if there is a film on the back of the phone that needs to be torn off, otherwise it will not work)
4. Restart the phone after posting, most of the phones have direct effects, and a small number of phones will experience signal weakening for a period of time. This is a normal phenomenon. This is the identification and matching stage of signal stickers for some mobile phone antennas. See the effect after hours, if the effect is not good, please try to restart several times or adjust the paste position.
5. Please be careful during installation and use, do not rub or break it with external force, please keep the signal sticker clean, do not directly touch the front of the chip with your hands, and the surface must not be stained with fingerprints or sweat
6. The material and thickness of some mobile phone cases will affect the chip effect. Please wear a mobile phone case for comparison. It is recommended not to use a mobile phone case when using this product.
