What should I do if R11 falls and then the cross is displayed on the left side of the signal grid?

Hello, the R11 mobile phone signal grid displays a cross sign, that is, your mobile phone is in the process of falling, the signal module is broken, and the line inside is damaged, so this cross will be displayed.

This one of yours should have fallen very badly, so it caused this plug number, in this case, it may be that the signal is not good for a while, and then turn on and try again after a while.

It should be that the mobile phone card has been misplaced, and you can take out the card slot and reinsert the mobile phone card.

That's a card reading failure, you can take the card out and reinstall it!

That's because the phone didn't read the SIM card, take out the SIM card tonight and reinstall it to see if it can be read successfully, if it can't be read normally, it may be a problem with the card slot.

If your phone is dropped, there may be a problem with your internal card slot. You only need to take out the SIM card and check it again, and the general problem can be solved.

You can try to turn it off and restart it, or reinsert the phone card, if it's still like this, it may be that something inside is broken.

This may be a loose mobile phone card, and the mobile phone card should be not detected.

The phone fell a little, maybe the phone card fell misplaced. In this way, there may be no cell phone signal.

You can turn off the phone and reinstall the mobile phone card to see, if it still doesn't work, you have to send the flower mobile phone store to check and repair it.

21 fell, and then the signal left and right showed a cross if what to do, I suggest that it be taken directly to the repair shop to repair it, because this kind of thing, I think it should be more difficult to do if it is broken.

If there is a fork in the location of the mobile phone signal, it is generally a network signal problem, and the mobile phone has no signal because the signal will be affected by various factors such as terrain, landform, and high-rise buildings during the propagation process, if your location is relatively closed.

This means that the card has no signal, or the mobile phone card or memory card is not detected, you take out the card slot, turn off the phone, and reinstall it.

21 fell, and then a cross was displayed on the left side of the signal grid, indicating that the receiving signal above had appeared, and the acceptance was seriously bad.

Hello, that should be the reason why you didn't insert the card, you can try to plug in the mobile phone card first.

This may have caused your phone card to fall off, and it is recommended that you take out the phone card and reinstall it.

This situation is a failure that only happens after you fall.

There is a problem with the components in the phone, and this is due to the hardware.

It's not software, so the only way is to take it to a phone repair shop for replacement parts and repairs.

I don't know what the hardware is, but the mobile phone must have an operating system, so it must be a smartphone, so the CPU or something is indispensable.

· S60's mobile phone definitely doesn't support this,No hardware requirements,The main thing is that the mobile phone browser supports flash,At present, most mobile phones can only be on the happy network,But you can't receive food··

All mobile phone systems in the world are stored in the flash module of the mobile phone. Can the software install the system? I don't think there's such a statement...

The friend operating system is integrated with all the hardware running, and the operating system is not added casually.

Hardware refers to components that can be seen and touched.

Software refers to components that cannot be seen, touched, but can be used, so the operating system is software.

So the question you are asking is problematic.

Of course, all software is installed on hardware.

On a computer, the vast majority of software is installed on a hard drive.

In layman's terms, both flash memory and hard disk storage media.

There is no hard disk on the phone, but it can be installed on flash memory, which is often referred to as flash ROM

Go to Saipan Smart Network to find out.

The main ones are iOS, Android, Symbian, Windows Phone, Blackberry, Meego, Bada, and some are based on the open source modified version of Android.

Xiaomi phones also have their own operating system, and they are updated quickly.

I don't know the difference, but I can only introduce the advantages and disadvantages of the main four operating systems, Symbian and Windows CE, Palm, and Linux, as well as representative models. Symbian: Symbian is very much like a combination of Windows and Linux, with a good interface, using kernel and interface separation technology, low hardware requirements, support C++, VB and J2ME.

Poor compatibility. Representative models: Nokia 6600 Sony Ai P908 Siemens SX1; windows ce：

Due to Microsoft's strong strength, Windows CE has many inherent advantages, and it is difficult for similar software on other systems to be so perfect and unified. Due to the extremely high hardware requirements, the power consumption is still very large, and the system stability is poor. Representative models:

Dopod smartphone series. Palm: This kind of system has very low hardware requirements, so it can be well controlled on **, and the power consumption is also very small.

Due to the relatively early appearance of the Palm, there are still many imperfections in the application on the mobile phone, and the same as the other two major systems, the Palm appears to be relatively weak. Representative model: Samsung SGH-i500TREO:

Linux has the advantages of open source, low software licensing cost, and abundant application development talent resources, which is convenient for the development of personal and industrial applications. Started too late and didn't have a solid foundation. Representative models:

Motorola A760, Samsung i519 .

The mobile phone operating system is actually the management system of the mobile phone application, and the functions of the general mobile phone are not the same, the operating system is not the same, and the operating system of each brand is different. There is generally no problem, and the various operating systems have been rigorously tested.
