Thinking of buying a Samsung Galaxy A40? If so, surely you are checking websites in search of reviews or possible problems that you may find on this device.
We have already mentioned the features of this mobile before, and we have even compared the Samsung Galaxy A40 with other Samsung Galaxy A series options. And now we will focus on some problems reported by users in popular forums.
But don't worry, most problems are just a matter of configuration, and can be fixed with just a few clicks. And if you already have your Samsung Galaxy A40, take a look at this information that will help you solve some of the most common problems.
WiFi is constantly disconnecting
This is a problem that is almost common in some Samsung mobiles. But don't worry, you can try several options to solve this problem by adjusting some details of the configuration. Get started by trying these suggestions:
- Turn off "Wifi Search". This is an option the device uses to improve GPS accuracy, but it can sometimes cause conflicts. To disable it go to Settings >> Settings >> Location >> Location method >> Phone only >> Improve accuracy
- "Keep the WiFi active with the screen off." Make sure you have this option enabled so that the WiFi doesn't keep disconnecting. Otherwise, it will stop working when the screen turns off. To do this, go to Settings >> Connections >> WiFi >> Advanced
And if changing these configuration options does not solve the WiFi problem, then apply a more extreme measure. Delete the data from the WiFi network and configure it from scratch. Perhaps some update of the mobile software is causing conflicts with the router configuration.
The screen is not responding
The mobile screen does not respond or reacts with delay ? The number one suspect for this problem is the screen saver. So check that this is not your case.
If the problem persists, then choose to adjust the screen sensitivity. To do this, just go to Settings >> Display >> Screen sensitivity. This option is an extra help to interact with the mobile using a screen saver.
Another option that you can try to detect if there is a problem on the screen is using applications such as Touch Screen. You will run a series of tests to check for problems with the touch response of the screen. This way you will know if it is a configuration problem, if only one area of the screen is affected or if you really have a problem that requires technical assistance.
On the other hand, if you notice that the screen freezes or the tactile response is very slow when playing games, it is possible that your long gaming sessions are the problem. If you spend many hours continuously playing, you can affect the performance of the device. And of course, the screen.
The mobile heats up and the battery lasts little
When does your mobile overheat? Try to establish a pattern to find the cause of the problem.
For example, the mobile of some users increases in temperature when they use a particular application, if they spend many hours playing or playing multimedia content, etc. To solve this quickly, try one of these alternatives:
- Do a mobile check to see if there are any problems. To do this, go to Settings >> Device care >> Optimize. This will tell you if there is any abnormal battery consumption, which may indicate that there are problems in the configuration of the mobile, or apps that are working improperly.
- Adjust details of battery settings to improve performance. Go to Battery >> Advanced settings and you will find a series of options to configure, such as screen brightness, standby time, background applications, etc.
And if you don't want to get complicated with these settings, simply choose "Adaptive battery" which will allow the mobile to use the best settings to optimize the battery according to your activity pattern.
Bluetooth doesn't work
Bluetooth on some mobile devices can be a real headache. If you have this problem on your Samsung Galaxy A40, try these options.
To avoid trial and error, directly clear the Bluetooth cache and pair the devices from scratch. So the first step is to go to Settings >> Applications and select “Clear cache” within the Bluetooth section.
Then remove all paired devices and test Bluetooth operation with just one of them. Perhaps the conflict is created with one of the devices in particular or having too many gadgets connected.
On the other hand, check that the optimization of the battery does not prevent the operation of the Bluetooth when it drops a certain level of charge.
Problems making calls
Users have had different problems on the Samsung Galaxy A40 while receiving or making calls.
- The touch screen is activated when answering a call
Some users report that they have problems with the Samsung A40 in calls since when bringing the face closer the screen is activated. That is, the screen does not turn off, the touch continues to work causing keys and options to be activated inadvertently.
Some think it could be a proximity sensor problem. In that case, there are not many possible solutions, just try if it works with some of these tricks. For example, if you have a screen protector, try removing it to see if this is creating a conflict with the sensor.
Or you can use third-party solutions to calibrate the sensor automatically. For example, Reset Proximity Sensor in an app that automatically fixes any device sensor issues.
And if the Samsung A40 doesn't use this proximity sensor, then focus on the screen. As we saw in the first item on this list, you can calibrate the sensitivity of the screen so that it does not cause problems.
- Audio is low on calls
If this is your problem, start by trying the basic options. Check that the earpiece area of the mobile is clean (you may be able to gently brush a toothbrush to remove any trace of dust) and make sure that the volume of the device is adequate. For this, it is not enough to press the volume buttons but you have to go to Settings >> Sounds and vibration.
On the other hand, if you have applications to record calls make sure that they are not causing conflict with the audio in the calls. You just have to uninstall them and test if the audio improves.
Vibration when playing the keyboard
Some users have complained in the Samsung forums that they do not find the option to activate the touch vibration for the keyboard that comes by default on the device.
Unlike other Samsung, this model does not seem to integrate this option so you will have to use third-party options. For example, you can download GBoard, set it as the default and then from the keyboard settings you choose the intensity of vibration you want.
Constant sound of notifications
I hope you do not have to live the hell of some users who have had to deal with the sound of notifications even when they had them disabled. A real headache.
It is not clear if it is a problem with the software or with some of the installed apps, but if this is the case, try Safe Mode. To do this, turn off or restart the mobile and when you turn it on (when you see the Samsung logo) press and hold the volume down button.
If you have done well when the screen appears you will see in the lower corner "Safe Mode". Try being in that mode for a while to see if you keep having the same problem. Since this mode allows us to simulate as if we had the factory configuration, we can establish if one of the apps is the problem or some bad configuration that we make on the mobile.
The screen unlocks itself
Some users notice that the screen unlocks itself when they put the mobile in their pocket. This leads to inadvertent opening applications or actions.
For this problem there are several solutions:
- Set a type of lock, be it PIN, pattern, or fingerprint. That way, even if the screen is activated accidentally, you will not be able to enter the mobile
- Activate the "Protection against accidental touches" option. You will find this in Settings >> Display. An option designed to carry your mobile in your purse or bag without problems
- Deactivate the option “Double tap to turn on the screen”, which you will find in Settings >> Advanced functions >> Movements and gestures >> Activate screen
- And on the other hand, pay attention with the apps that you allow on the lock screen. If you have any app that could get you in trouble if accidentally activated, then remove it.
Tips to keep in mind
As you will see, these solutions are applied by changing configuration options that will not affect the operation of the mobile. But if these suggestions do not work, then you will have to try a more drastic measure, such as factory resetting the mobile to see if the problem is related to the software update or a conflict with the apps you have installed.
But if you still have your mobile under warranty, do not start to perform experiments, consult directly with the technical service to provide a solution or replace the equipment. And of course, never forget how important it is to have your Samsung software updated, since these types of problems are usually solved with patches and new updates released by the company.
