Tianyu A909 mobile phone has been shut down recently, sometimes it can t be turned on 50

Tianyu mobile phone has this hobby. The same goes for my Tianyu A696. It didn't take long to buy it, and that's it.

It's been three years now, and it's still the same. There is nothing else wrong with it. It's pretty easy to use.

Try a different battery.

Hello, according to the situation you described.

1.It is recommended that you try to switch it on and off again.

2.It is recommended to try to replace the battery with a reseat attempt.

3.If your phone can operate normally, it is recommended that you back up the personal information in your phone in advance to avoid data loss, and try restoring it to factory settings.

4.If there is still a problem after trying the above methods, it is recommended to go to the repair station to test the mobile phone, and it is recommended to contact the Tianyu after-sales service center, the address of the Tianyu national after-sales service center.

Tianyu's machines are like this,Mine is Tianyu B880,After using it for a while,It's always automatically turned off and on.,The battery is full and it crashes.。

If you have enough money, you might as well buy another one!

I spent dozens of dollars to change a smart version, but it still didn't solve the problem.

Your battery is a non-standard battery, and the machine doesn't recognize it, so it's equivalent to running out of power, and of course it's turned off. Processing: Buy an original battery and it's OK

The copycat machine is like that, okay, let's change it to a new one, haha.

There are several cases when the phone automatically shuts down:

1.The connection between the mobile phone battery and the mobile phone contacts is loose or poorly connected, if it is loose, you can take the method of adding something to fix the battery and let the battery and the contacts fully contact; If the contact is bad, you can use a home toothbrush with a little alcohol and wash it back and forth between the contacts of the battery and the contacts of the phone.

2.The battery is aging, if the battery is used for too long, there is also this possibility, the detection method is to try to change a battery, if the problem is solved, OK, you can only change the battery, the problem is still there, then it may be a mobile phone problem.

3。If it is a mobile phone problem, then there are only two possibilities, one is the motherboard, the other is the software, the motherboard problem can only be repaired, the software problem can be solved by flashing, no need to disassemble and repair.

I used to have a mobile phone like this, but then I accidentally changed the SIM card and it got better. (Later, I came to the mobile company and asked that the batch of 134 cards we had here had problems, but they behaved differently on different mobile phones), and then one of my colleague's mobile phones suddenly had such a failure (but his card was used for more than a year) and it became better after changing the card. It doesn't necessarily help you, but you can give it a try.

Ha ha. Good luck. There are also a few people upstairs who said that the battery problem should not be, because if the battery is in poor contact or something, he will not turn on again after turning off (just like we take out the battery and put it on immediately, will it turn on if we don't press the power button?). ）。

Poor battery contact! Grab some small pieces of paper and try it out!

1. If the hardware is damaged, it may also lead to frequent crashes. Mobile phones are sophisticated electronic products, in which the circuit must be in a more stable environment to work normally, if the mobile phone often works in a humid environment or is subjected to strong vibrations from the outside world, it may crash. For example, sometimes we accidentally drop our phone on the ground, and the phone may freeze.

Therefore, we must treat mobile phones kindly and try to handle them gently; Don't let your phone get into water and try not to use it in a humid environment.

Usually, if we operate the phone improperly, it will also cause the phone to crash. Especially when we are texting, if the speed of key operation is too fast or the short message bombardment is continuously in a short period of time, the mobile phone CPU load is too large, and the heat generated by the CPU cannot be dissipated in a short time, so it will cause the mobile phone to crash. Therefore, when we use mobile phones, we must pay attention to the operation; And try not to disclose your mobile phone number to avoid being bombarded with text messages.

In addition, there are other factors that cause the freeze due to hardware issues. For example, the aging of hardware, the use environment of mobile phones is too harsh, etc.

2. Software issues.

The main reason is that there is a fatal bug in the software design of the mobile phone, which causes the crash. For example, when the mobile phone runs a program, if there is a logical error between the subroutine and the main program, every time the mobile phone runs to the program, an instruction error will occur, a bit like an illegal operation in the computer, and there may be a crash. Crashes caused by software bugs generally have the following characteristics:

Crashes occur every time a command is run, i.e. every time the same operation is performed. If your phone keeps crashing like this, you can preliminarily conclude that it is due to software problems. Solve such a crash can be solved by software upgrade, now the major mobile phone manufacturers have customer service centers, all provide free software upgrade business, however, such an upgrade can only upgrade the software version, the function of the mobile phone will not change after the upgrade, but some software bugs are solved in the upgrade, reducing the probability of crash.

Nowadays, there are many mobile phone diyers who like to upgrade the software of the mobile phone, which has caused instability to the mobile phone, so it is best to go to the customer service center to upgrade the software of the mobile phone, if you do the upgrade yourself, please make a backup in advance, so as not to restore the software after the mobile phone upgrade fails.

In fact, it is normal for a mobile phone to crash like a computer crash, as long as we treat it correctly, there will not be so many people complaining that their mobile phone is dead again. But if your phone often crashes, you have to pay attention, it is best to send your phone to the customer service center for maintenance, that is the best solution

Hello, through your description, it can be basically judged that it is caused by CPU virtual soldering.

It is recommended to go to Tianyu after-sales service center for hardware maintenance.

The address of Tianyu National After-sales Service Center.

If the program is malfunctioning or there is a virus, it is recommended to take it to the mobile phone store for a comprehensive examination.

1. The power contact of the mobile phone is loose or damaged, resulting in poor contact with the battery.

2. There is a conflict problem in the mobile phone system, resulting in automatic shutdown.

There may be leakage, resulting in a high standby current, the battery runs out quickly, and how long has the battery been used? Is it aging?

Wipe the battery in touch and see if it will get better.

Has your phone been dropped... That's what mine is... Frequent automatic shutdown.

2) Whether there are too many background programs running, close or stop background programs.

4) Try to kill viruses or restore important data of the phone to factory settings.

If it still doesn't work, it is recommended to take the mobile phone to Tianyu's repair station for testing and maintenance, and the address of Tianyu's national after-sales service center.
