Why did the Apple 12 phone signal suddenly get weaker

1. The mobile phone case affects the WiFi signal.

Most iPhone users will wear a case for their iPhone, but some third-party cases, especially metal cases or metal bezel cases, can affect the WiFi signal. If the WiFi signal on your iPhone is not good, you may wish to remove the case and try it to see if it improves.

2. Reset network settings.

It is also possible that there are some problems with the system of your iPhone if the WiFi signal is not good, and some problems can be solved by restoring the network settings of iOS. Go to Settings - General - Reset - Reset Network Settings to restore the network of your iPhone, this restore will not reset other data of your iPhone, but some wireless passwords stored on your phone need to be filled in again. After waiting for the system to restore and restart, try connecting to a wireless network to see if the signal strength improves.

3. Upgrade the latest system.

Firmware updates for iOS often include fixes for various bugs and errors, and sometimes optimizations and enhancements to this part of the network. If the WiFi signal is not good and you are stuck in the older version, you may wish to upgrade to the latest iOS8 system to give it a try.

4. A router.

If you rule out the cause of the iPhone itself, you might as well see if there is something wrong with the router. You can try restarting the router or resetting it to factory settings. If there is no problem with the router, you need to consider whether it is a hardware problem with the network operator or the iPhone.

One is that the mobile phone has been used for a long time and has aged, and the other is that the mobile phone has too much garbage.

Summary. In response to the problem of poor signal of iPhone 12, you contacted Apple's official customer service, and Apple's official customer service responded that it is recommended to reinsert the SIM card, update the carrier settings, and update the system.

Apple's customer service said that it has not been notified that it is a hardware problem for the time being, and it may be a software conflict and intermittent problem. If it is indeed caused by the hardware, the corresponding solution will definitely be given.

Theoretically, after using the Qualcomm baseband chip, the signal performance of the iPhone 12 will be significantly improved, after all, the stability of the Snapdragon X55 baseband has been tested by many Snapdragon 865 flagship phones. Therefore, this problem is likely to be Apple's software, after all, this is the first time for Apple to make a 5G mobile phone, and it is not surprising that there is a problem.

Why is the Apple 12 signal so bad.

What is the reason for this blue.

This basket has always been there??

Because this one was opened.

It would be nice to close this again.

Close, there is no basket.

1. If the iPhone12 mobile phone signal is not good, then you can try to upgrade the system to the latest version, and the new system will generally be more friendly to new models like iPhone12.

2. How to upgrade the iPhone system: Open [Settings] - [General] - [Software Update], as long as there is a new version, it will prompt.

3. In addition, it is recommended to reinsert the SIM card and update the operator settings, which may also reset the mobile phone signal.

4. iPhone12 mobile phone uses Qualcomm X55 baseband, this baseband in addition to iPhone12 in use, many domestic mobile phone manufacturers are also using this model of baseband.

Check that it's the phone itself.

Or a network issue.

Or it's a matter of where you're in.

After it is detected, it will be resolved on a case-by-case basis.

If there is a problem with the phone itself.

You can choose to go for maintenance or after-sales service.

Network problems Just try another network.

The location problem is OK to change places.

The first step is to enter [**] The second step is to enter *3001* on the dialpad, and then press the [Call] button, the iOS built-in app Field Test will be launched, and the exact value of the signal strength will also appear in the upper left corner. Step 3, press and hold the iPhone Switch button (i.e. the top power button) until the "Slide to Power Off" slider appearsStep 4, and finally press and hold the Home button until the power off slider disappears, the phone will return to the home screen interface Step 5, at this time, the signal strength value will always be displayed in the upper left corner of the iPhone screen, you can also click it to switch between numbers and signal bars. There is actually a hidden app in the iPhone usage tips, which can be used to detect the iPhone signal, the iPhone cellular network value, and it can accurately display the strength of the mobile phone signal with numbers.

And it allows you to switch between the grid and the value by doing the following: the lower the number, the worse the signal. In general, between -40 and -50 is near the base station; The signal between -50 and -60 is very good; The signal between -60 and -70 is considered good; -70 -80 is a slightly weaker signal; Between -80 and -90 is a weak signal; -90 or less is the basic communication state.

100, it is recommended to sleep at night or turn on the airplane mode, otherwise it will consume power and radiate a lot! Manually selecting a carrier, your iPhone will automatically connect to the appropriate network based on your card. However, the iPhone sometimes has convulsions, if you have a poor signal, you can manually select the network to try.

Go to [Settings] - [Carrier] - [Turn off auto] and so on, search out the network, and then select the corresponding carrier according to your card. For example, mine is a mobile card and chooses China Mobile. Switch on and off the flight mode, sometimes we are in the position of the cross-base station, and the signal diving is unstable.

You can try toggling the airplane mode, first turn on the airplane mode for 5 seconds and then turn it off, and then see if your signal is full of health. Reset the networkIf you try the above two methods, the signal is still very poor, it may be a problem with your network settings, you can try to reset the network to see if the signal improves!

Apple's iPhone 12 series has officially gone on sale, although the machine has a small battery, low fast charging power, and does not come with charging heads and headphones, but for many users, supporting 5G network is enough, which is the biggest upgrade point of the iPhone 12 series. Indeed, the most basic thing about a mobile phone is the network, and other functions can be used, so what is the network signal of the Apple iPhone 12 series?

Due to the weak signal of the previous generation of iPhone 11 series, Apple has been complained by users, and as for the reason for the weak signal of iPhone 11, it is generally believed that it is caused by Intel's baseband. Compared with the iPhone 11 series, the iPhone 12 series should not have the problem of weak signal, because it is confirmed that the iPhone 12 series uses the Snapdragon X55 baseband, which is the same 5G baseband as most Snapdragon 865 Android flagships.

According to the signal of many Snapdragon 865 flagships, the iPhone 12 series should not have a weak signal, but this is not the case, and the signal of the iPhone 12 series is still weak compared to Android flagships. It's not just that the signal is weak, the iPhone 12 series also has a more serious problem, according to the feedback of netizens, the iPhone 12 will occasionally have no signal, ** can't get in, and it needs to be restarted to solve it.

Finally: the same Snapdragon X55 baseband, the iPhone 12 series signal is still weak, so it should have little to do with the baseband, and considering that the iPhone 12 series has just been launched, the system optimization is not ideal enough, so it is recommended to wait for the new system update to take a look.
