There is a chance that the baseband is damaged, but the odds are small. Baseband damage is hardware damage and needs after-sales repair.

It may be the cause of the system, and you can solve it by resetting the system to factory settings.

Generally, baseband damage is divided into the following three situations:

1. Fall: Most of the basebands are not damaged, generally only in the lower right corner of the mobile phone directly touching the ground in the impact is easy to damage the baseband, it is recommended to install a protective film for the mobile phone.

2. Flashing: Flashing jailbreak and unlocking these are all to make the CPU baseband work with high load, the damage to the baseband is relatively large if the number of times is more, and the flashing is risky, and jailbreak needs to be cautious, and minimize the number of flashes without affecting the use.

3. Water ingress: Bad base band is an accident, and the probability is small, but it is still necessary to pay attention to staying away from water sources.

4. If the baseband is damaged and affects the use, it is not recommended for non-professionals to replace the baseband by themselves, please go to the local after-sales point to replace the baseband.

Causes of this situation and how to fix it:

1. Most of it is caused by the small iron piece on the wifi signal cover, disassemble the back cover of iphone4, there is a baffle for covering the LCD screen cable, there is a protrusion point on the baffle, and a semi-circular small iron block. If your wifi signal is not good, you have lost this thing, users can buy it online and install it themselves, or you can go to a repair shop to repair it;

2. The function of the signal cover is to connect to the small contacts on the motherboard through the bump on the small iron sheet in the above picture to enhance the wifi signal, if you rule out the first reason, you can try this method, the mobile phone that has been used for a long time, due to the motherboard exposed to the air, the small contacts on the motherboard are caused by oxidation, take a knife or something like that and gently scrape it, scrape off the oxidized part, and then install it back and you will find that the user's wifi signal is full again.

3. If the above methods cannot solve the user's problem, it is best to ask in the Apple store and ask a professional.

Probably not. It's a 4G to 2G drop.

iPhone6 signal is not good solution:

1: Toggle the airplane mode on/off.

When we use the iPhone in our daily life, we will occasionally find that the mobile phone signal is unstable, sometimes there is no signal, sometimes it is full and sometimes there is only one grid. Turn on the airplane mode first, wait for about five seconds, and then turn off the airplane mode, and you will find that the signal of your iPhone has "flew" back!

2: Manually select the carrier.

Generally speaking, the iPhone will automatically match after inserting the mobile phone SIM card and access the corresponding operator network, but many netizens find that there is a bad mobile phone signal or no service, and they can manually select the operator network. Enter the carrier option in the settings, turn off the "automatic" function, wait for a while and the network operator will be optional, users only need to select the corresponding operator according to their mobile phone card.

3: Reset network settings.

After trying the above two methods, the mobile phone signal is still very poor, and users can also try the method of resetting the network settings. How-to: Settings - General - Restore - Restore Network Settings.

4: Re-flash.

If you can't try all the methods, it is recommended that you take your iPhone to Apple for after-sales testing!

The antenna of the bai in the mobile phone is responsible for the reception.

DU signals, smartphone antennas are generally designed in the bezel DAO. I'm not mistaken,The antennas of these generations of iPhone are all in the bezel,So you will see a lot of different materials at the bezel,That's a design made for the antenna.。。。

When you fall, did you fall from the side? It is estimated that the antenna hidden inside was affected in the process.

The back cover antenna is in poor contact.

Go to the store and see the best places to identify.
