The situation when a user puts a smartphone on charge, but it does not receive energy, happens quite often.
In some cases, the gadget also stops responding to touch. In this article we will try to figure out what may be the cause of the problem.
Charging connector is dirty
One of the main and most common reasons why a phone stops charging is a dirty charging port. Many people like to carry devices in the pockets of jeans and bags, which is why over time the connector becomes dirty and dusty.
The first step is to carefully examine the USB port, blow it out (this can be done using a can of compressed air) and carefully clean it with a toothbrush. Please note that this procedure must be performed with extreme caution, as the contacts may be damaged, which will lead to more serious damage.
Oxidized contacts
In some cases, the smartphone does not respond to charging due to oxidized connector contacts. Such a breakdown can occur if the device has not been used for a long time, water has entered the connector, or the device has been used in conditions with high humidity.
You can clean the contacts - you need to take the same toothbrush, moisten it in alcohol and carefully clean the port. This operation can also be performed using a thin needle. Before carrying out the procedure, you must turn off the device and, if possible, remove the battery from it.
Worn out battery
Even though the batteries modern smartphones They are quite tenacious, they cannot serve forever. Each battery has a limited supply, and sooner or later the time comes to replace the battery.
Protective film
Many people strive to protect their smartphones as much as possible and use all kinds of protective films and glass for this. They may be the reason why the display stops responding to touches. The problem may be caused by poor-quality gluing, when air bubbles and dirt remain between the film and the screen, which prevent the device from being controlled. Remove the protective element and check the phone.
Screen calibration
Do you press on one part of the screen and the display responds on the other side? Does the screen just not respond to your touch, no matter how hard you press it? Connect a mouse to the gadget and try.
Problems with the touchscreen control chip
Similar problems can arise if the phone has been dropped or moisture has gotten inside the case. To understand what exactly the problem is, you need to take your smartphone to service center, since only specialists can deal with such problems.
A modern smartphone, which makes human life easier in many ways, often causes stress. This happens if the phone is buggy. The era of immortal gadgets has passed - now devices have become more complex in their design and software content, due to which they break more often.
To avoid unpleasant emotions, you should treat it with care and monitor its condition. But if enjoying the functionality is already hampered by the fact that your smartphone is buggy, it will tell you what to do. In most cases, even if the phone is frozen and does not respond, you can fix everything yourself. It is enough to determine the cause of the breakdown and find a way to eliminate it.
Where to begin?
First, it’s worth determining exactly why the phone is buggy. Basically, faults are classified into two types:
- Mechanical damage
- Violation in the functioning of the software
Many believe that if the screen of their smartphone is intact, and the cover is not held on by tape, then the gadget is in perfect order, and the problem of malfunction is caused by a software failure, not understanding what to do if the device freezes and does not respond to actions.
However, this is not always the case - even one loose contact inside the device can affect the operation of the device, and the aluminum case and protective glass can hide the malfunction, due to which it freezes and does not respond to anything, from the user’s eyes.
Software failure
Freezes when turned on
One of the most common reasons why a phone glitches and users wonder what to do is when it freezes when turning on. You can solve this problem as follows:
What should I do if my phone freezes for a long time and does not respond when turned on? First of all, you need to hold down the volume key along with the power key. Using the volume keys, in the menu that opens, select the Settings item. The select (click) button is the power button. There you should select formatting the system (this will erase all files except system files).
Once formatting is complete, click on Reset android, which will reboot the device, after which the device should return to normal operation. One of the reasons why a fairly reliable Android phone is buggy was considered without the participation of a service center! Now the device should not freeze when turned on. The solution can also be used when you don't know what to do if your phone is frozen and not responding to anything.
Stuck on shutdown
It happens that the phone does not turn off, freezes, refusing to respond to any buttons or presses on the screen. This happens extremely rarely, but you need to know what to do in this situation. To restore functionality, just remove the battery and after 10-15 seconds insert it back. In 90% of cases, this method helps to cure an unpleasant operating system glitch.
If, after the completed procedures, the phone freezes, then you should contact the specialists, most likely the problem is not android platform, but in the hardware of the gadget. It is difficult to predict anything here; each case is individual.
Other types and causes of freezing
As a rule, the reasons why the device does not work correctly, freezes and does not respond (for example, applications installed in the gadget do not respond) are factors such as a lack of hardware resources or memory. Let's figure it out sequentially.
Resource-intensive applications - running in background, they often ruin the life of users by absorbing the device’s resource and slowing down its operation. They may be the following programs:
- Widgets on the desktop
- Background sync
- Push notifications
It is quite difficult to figure out which program consumes the most resources. What to do if your phone is frozen and not responding?
Solution
What to do if your Samsung phone freezes and won’t turn off? If a Samsung phone malfunctions in this way, solving the problem is quite simple - just hold down the power key for 20 seconds, after which the device will vibrate and reboot.
For devices from other companies, you can use the same method, but it does not always work. What to do if the solution did not help and the gadget is still buggy? In this case, you need to hold down not only the power key, but also one of the volume keys - the same thing will happen.
Wakelock Detector
One solution is to install the Wakelock Detector app. The program will help identify the most power-hungry applications. After the application is installed, the device should be charged to 90% and disconnected from charging, leaving the application on for 1-2 hours (during this time statistics will be collected).
After this time, launch the application - you will see the analyzed statistics in it. The topmost programs consume the most resources. Disabling them optimizes the operation of the device. This is the bottom of the main thing that needs to be done so that the phone does not freeze.
What to do if your Samsung phone still freezes? Perhaps the fact is that there is little free space left on the memory card or memory of the device itself.
When the memory is 80% full, some devices begin to perform much worse. From time to time it is worth doing a thorough cleaning of your device. First, you should get rid of obviously unused programs and irrelevant files. You can do this manually or use a special application - clean master. After installing it, you can get rid of garbage in a few clicks. It's also worth clearing your cache.
Minor problems
The device can frustrate the user with smaller, but still unpleasant glitches. Let's look at their solutions:
- The lost network signal is restored by switching the device to airplane mode and then turning off this mode.
- If it is difficult to detect the SIM card, you should remove it and return it to the slot.
Conclusion
As you can see, there is nothing difficult in getting rid of errors and glitches in the Android system. Any user can solve problems in no time; just read this article. Be careful and careful, and everything will work out, see you on the pages of the site!
