Does your Samsung Galaxy A70 give you some headaches? Although it is a powerful mobile device with an interesting combination of features, it has presented some problems, as reported by users in different forums.
They are not generalized problems, but if you encounter some of these problems, don't worry, we will help you by suggesting some possible solutions.
Doesn't recognize fingerprint
If it happens to you like some users that the Samsung Galaxy A70 does not easily recognize your fingerprint, it may be your problem when configuring this option.
Do not forget that it is important that you put your finger in different positions when registering the fingerprint so that the sensor can recognize it easily. And if you have time, register the same finger twice to improve performance.
So if you want to test if this option works on your device, delete all the records you have created and start from scratch by following these tips. And if this option does not work, you can go to the plan by lowering the sensitivity of the screen in case you use a protector that prevents the correct touch operation.
To do this, go to Settings >> Display and choose Touch sensitivity.
Proximity sensor problems
Some users have reported problems with the proximity sensor causing their calls to become a mess as it does not turn off the mobile screen. And others, by interacting with different applications.
There is no definitive solution for this, but you can try a few options. For example, Samsung forums advise removing the screen protector as it may cause conflict with the operation of the sensors.
And if it still persists, try “Reset Accessibility Settings”. Or you can use applications like Proximity Sensor Reset that allows you to calibrate the proximity sensor for its correct operation.
The process only requires a few steps so you won't get complicated with settings or advanced options.
It won't connect to my home WiFi
If your Samsung Galaxy A70 connects perfectly to any WiFi, but you arrive at home and it is as if the connection does not exist, you may have to adjust the router settings.
An option that has worked for some users only requires one change. You enter your router's settings, go to the Network Settings section and look for advanced settings to change an option in “802.11 Mode”.
Once you find this section, choose "bgn-mode Mixed", or a similar option depending on your router model. For example, the DIR ‑ 880L router presents the option like this, as illustrated in its Help Center:
On the other hand, if the problem is that your Samsung is intermittent then check if you have configured the option to keep the WiFi always active.
To do this, go to Device Settings >> Connections and select WiFI. Choose Advanced Options and make sure you have this option enabled correctly.
The mobile gets too hot
This is not a widespread problem with the Samsung A70, but some users have reported this. Maybe it just has to do with usage habits.
If you notice that your mobile is warmer than normal at certain times, for example, when playing a heavy game, loading it or having too many apps open, try to change this dynamic. If nothing changes and you notice overheating on your device, then check if there is a problem with battery consumption.
To do this, go to Device care and choose Optimize, as you see in the image:
And then, go to the Advanced Battery Settings and customize some options to improve its performance, for example, screen brightness, open apps, etc.
If none of this works, a last step to know if there is a conflict in the device software that causes this overheating is to reset the values of the mobile.
Problems playing PUBG
Some users noticed that the touch screen was not responding properly when playing PUBG. In some cases it froze or delayed movements. But this is an issue that was fixed with one of the software updates, so it shouldn't happen anymore.
On the other hand, keep in mind that if you play for hours that also affects the performance and the screen. And not to mention if you play while charging your mobile. But if you have doubts about the operation of the touch, try an app like Touch Screen Test
Bluetooth constantly connects and disconnects
There is nothing more irritating than plugging in your Bluetooth headphones and spending time nagging because the connection doesn't last more than a few seconds. If that happens to you frequently on your Samsung Galaxy A70, try some of these options.
In the first attempt, disconnect all the devices that you have paired and start the process again. Perhaps a conflict has been created at some stage or between the devices. For this you must go to Settings >> Connections >> Bluetooth.
If this does not work, the second option will be to delete the Bluetooth cache from Settings. You go to Applications >> Show system applications >> Bluetooth >> Clear cache. And if the problem still persists, use an external help such as the Bluetooth Auto Connect application that automatically starts the process detecting if there are problems in some of the devices.
Whenever your mobile device has these types of problems, make sure that the conflict is not caused by a software update. Since if that's the case, you will have no choice but to wait until Samsung sends out an emergency patch or update.
And if problems persist despite trying some of the solutions we mentioned then check with Samsung support to verify that it is not a hardware problem.
