During this guide, we’ll use the recovery mode and some inbuilt features to perform troubleshooting actions. Basically, recovery mode runs independently and it is like more maintenance mode. To access this mode, there’s is a certain pattern in which users need to press the hardware keys. Or there are more methods to get into this mode.

Troubleshoot common problems on Samsung Galaxy M20

1. What to do when WiFi won’t connect on Samsung Galaxy M20

No matter whether you have an iPhone or Samsung’s flagship smartphone, this problem can happen. You might be trying to connect your phone to a particular WiFi source, but that couldn’t happen so. There can be different reasons for this problem. Thus, you would need to apply different solutions to fix this problem.

Since WiFi offers extensive Internet speed and data transfer facilities, we can’t ignore this problem. Try the following solutions to fix this WiFi won’t connect issue on your Galaxy M20:

  1. If you were previously able to connect to this WiFi source successfully, you better reboot your phone first. Just a reboot fixes many problems including networks, performance, and stability.
  2. You must confirm whether other devices are able to connect with that WiFi source or not. The problem may be associated with the WiFi router. If other devices are connecting to that WiFi router, just follow the recommendations.
  3. If that’s your home WiFi or one that you can access, you can try to perform reboot that router. After that router turns ON, connect your phone.
  4. If that doesn’t work, probably, the problem is somewhat on your phone. There’s nothing to worry, just open the Settings -> WiFi & Internet-> WiFi->Saved Network and tap on the Network that you’re connecting. Then, tap on ‘Forget’ button. Form a completely new connection.

One of these should have fixed the WiFi-related problem on your phone. If you still find these solutions aren’t helpful, do let us know. We would try our best to help you further.

2. Mobile Bluetooth doesn’t pair with other devices

Almost similar to the WiFi problem, this usually happens when a user tries to pair Bluetooth headset or similar devices. For me, it happens when I try to connect to my speakers and headphones. To solve that, I usually reboot my phone and these Bluetooth devices and that work for me. Here are some recommendations that should help you fix this problem on your phone:

  1. A reboot worth your try. Most of the time, just rebooting fixes these problems. Try to restart both devices, your phone, and that Bluetooth device. Most probably, this should fix the problem.
  2. Next, you could try to forget the connection if you’ve previously paired that device successfully. Just open Bluetooth settings and tap on saved networks. Now, tap on that Bluetooth device and tap on ‘Forget’. Now, again pair that device.
  3. If you’re connecting the device for the first time, there are chances that your phone might have reached its limit to form connections. Again, open the Bluetooth settings and tap on save networks. Now, remove some connections. After that, try to pair that Bluetooth device.
  4. Additionally, ensure that your phone is discoverable. Otherwise, no matter how many time we try. Open the Bluetooth settings and ensure that it is set to visible.

These are enough solutions to fix Bluetooth device won’t pair issue on Samsung Galaxy M20. If none of them work, you can try to reset Network settings your phone as well. That helps to fix network and connectivity related problems on the Android phone.

  2. If you observe that your phone becomes heated while playing games, then you shouldn’t worry that much. While playing games or using heavy apps, CPU and GPU units are continuously used and that heats up the device.
  3. If your phone becomes heated abnormally, there are chances that some apps running in the background and using power resources without a limit. Go to Settings > Battery > Battery Usage > More > Optimise battery usage, and tap ‘All Apps’. That will restrict the apps from using the battery unknowingly.
  4. Next, you can clear clutter data from your phone. Over time, our phone tends to gather a lot of clutter and garbage data that affect many aspects negatively. To clean your phone, open the Settings menu and tap on Storage. Under this menu, you’ll find ‘Clean Storage’. Tap on this button to perform this action.
  5. Moreover, you can wipe the entire cache partition on your phone using the recovery mode. That will thoroughly clean your phone. Just follow this tutorial for that purpose.
  6. If nothing seemed to work on your phone, you must perform a factory reset on your phone. This action will remove all third-party apps, configuration, and files. That leaves stock performance and stability.

In addition to that, there’s one more thing that you could do. There are chances that one or more recent apps that you’ve installed causing your phone to overheat. You can use the Developer Options->Running Services to observe abnormal behavior of those apps. And once your figure those apps, either you can disable them or uninstall.

That doesn’t only fix the overheating problems, it also improves the overall battery life. You can learn how to enable Developer Options on this phone and how to use it here.

4. Fix App crashes on Galaxy M20

Right after my phone got updated to Android Pie firmware, I realized that many apps have become unstable. That happened due to old cache files. So, right after that, I wiped the entire cache partition and that worked for me. Here are some useful recommendations that should help you fix app crashes on your Samsung Galaxy M20 smartphone.

  1. If you figure that a certain app is behaving abnormally, then you should clear its associated cache files.

6. Fix Slow performance and unstable Android interface

This is the most common problem that Android users suffer. Over time, our smartphone tends to become slower and there can be different reasons for that. Most of the time, through basic cleaning actions, these problems are resolved. Such problems happen due to cache and clutter files that have been gathered throughout time.

Basically, the cache files are induced by the applications installed on the phone. Over time, these cache files become so huge that it impacts the overall performance and stability. Apart from that, there might be some apps or programs that affecting performance on this phone.

Here are some quick recommendations to overcome performance and stability problems on Samsung Galaxy M20 smartphone:

  1. If you’ve been using your phone for a long time, then probably there have been a lot of clutter data that been gathered on your phone.

  4. The above recommendations would help you restore the original performance. To make your phone faster, the following recommendations are helpful:
    1. Disable Unused apps. There would many apps that you must have not used so far and not intended to use in the future. So, remove these unwanted apps from your phone. This will boost overall performance on your phone.
    2. Switch to third-party launcher application. Although, Samsung has implanted many changes to their UI, still compare to third-party launcher apps, it is a little bit slow. We recommend you to use Nova Launcher or you can find alternatives.

Though these solutions are plenty enough, if you still don’t find helpful, you can try re-installing the entire firmware on your phone.

9. Low Speaker Volume on Galaxy M20

When it comes to low speaker volume, most probably there could two things; either phone’s speaker doesn’t output enough sound or the media file isn’t good enough. Further, there can be a problem linked to the hardware part as well. We have some useful troubleshooting solutions to cure such problems on Android phones. Here the fixes that you can apply on your phone:

  1. First of all, thoroughly observe the phone’s speaker. There might some dust over that resisting the full volume. You must clear those holes, there might be small particles stock over them.

10. Network issues on calls on Samsung Galaxy M20

Most of the time, the network issues happen based on geographical location and network strengths. If you’re residing in an area where network problems are more often, then there’s nothing you could on your phone. That’s what something your SIM operator service or higher authorities could do.

Otherwise, the following recommendation should work in resolving most the networking related problems on your Samsung Galaxy M20 smartphone. Just follow the below ones:

  1. Firstly, you should try to remove the SIM card tray, clean it thoroughly and re-insert your phone. That should fix problems caused by the disposition of the SIM card. That should bring some improvements to the network signals.
  2. Further, we would recommend you to reset the network settings on your phone. That will remove old settings and connections causing network issues on your phone. For that purpose, you can follow this guide.

    1. Hi Vinay, This is something done by the software. There’s nothing to worry since the same thing happens on different phones like OnePlus 5 and some other devices. You shouldn’t worry about it.

    1. If you’re facing sound eco problem during calls, then you must figure whether this problem occurs on certain numbers. Most of the time, this problem happens with certain numbers. Otherwise, you better report a defect on the mic to the service center.

  12. Hi
    I have bought the Samsung M 20 at the first release that is on 5th feb, i have been using since than without any problem. But recently i have shifted my company where i wont have proper signals, from that day when ever i am using my phone in the company it getting heated up very quickly with even small apps like watsapp and the battery is getting drained very quickly. Can you please suggest some solution for this problem?

    1. Hi there,

      There’s nothing to worry. Since you’re in the area where signals are low, the phone keeps trying to find and connect to the available network. And that makes it hot and it actually consumes a lot of battery.

      Here’s a solution that you could try. If you’re using 4G services in that area, we recommend you to downgrade it to 3G or 2G. 4G technology consumes a lot of battery power. Just open the Settings’ on your phone and tap on Networks. Then, choose 3G or 2G Network.

      This should definitely work for you.

      I hope it helps you. You’re most welcome to share you thoughts further!

  13. I have bought m20 Samsung mobile but I face problem on call its automatically goes to aeroplanes mode , it’s frequent

    1. Hi Manish,

      There’s nothing to worry much. You just need to reset phone’s settings. Just open Settings->Reset -> Reset Phone’s settings.

      Thereafter, you probably shouldn’t face this problem.

      I hope it helps you!

      This should help you fix unnresponsiness problem on your phone!

    2. Data/internet is not working while you are on the call over volte 4G.
      This is biggest problem of the device and need to fixed immediately else purpose of the phone will be defeated.

        Please correct this problem too.

    1. Hi there,

      There can be two things; either this issue is caused by hardware malfunction of the Senor or it is just due to the firmware. Therefore, I would suggest you try performing hard reset. This should probably solve the problem on your phone.

      Or else, you should visit the service enter.

    2. While call my screen remains active and on.

    1. Hi Abishek,

      This problem seems to be related with third-party application (that might be a virus or malware). You just need to try removing third-party apps that you’ve downloaded on your phone. Most probably, this could be caused by VPN or similar app.

      Try this and let me know if that works!

  18. Call volume is very low I can’t listen from opposite site but ring volume is full .now what I do

    1. That problem could be related to network, SIM or software. First I would recommend you to check with the SIM operator. After that, you can perform a factory reset on your phone.

    I am facing touch problem on my m20 often it responds self .
    After pressing lock button it will become normal

    1. It is firmware related problem. Either you could wait for new updates or factory reset this phone.

  22. Touch is working automatically ,maybe it is known as Ghost touch.
    Is there any solution for the same?

    1. Hi Jatin,

      This problem is somewhat linked to the firmware. I would recommend you to perform a factory reset and update it to the latest firmware!

  23. Touch screen working automatically. I already done the factory reset. Problem is as it was. What to do ??

    1. Hi Harish,

      This seems to be more problematic thing. Here are some suggestions:

      1. Remove the tempered or screen guard if you’re using.

      2. Try downgrading this device official firmware. You can follow this guide:

      3. Use sharp-thin blade and use it clean dirt or interaction between screen and the metal body. You must do this very carefully and on your risk only.

      4. If nothing works, take it to the service center.

      I hope one of these suggestions should help you!

  24. My m20 phone’s touch auto working and I am not able to work on this device. If you have any suggestion or solution please tell me.

    1. Please remove the animation and you will get rid of this problem. I did it and am fine now. Animation allows down the processor probably

  25. I bought m20 this month and just now i have started to notice there is a small dash like area on the top to the left of the front camera which shows a blue light like a flat dash is it default or it’s a problem in my phone.

  26. Hi,

    My mobile starts act weird at most of the times, for ex : while i am operating whatsapp it stuck in the middle and starts operating automatically opens wrong message window starts typing and being sent, also most of the times it will take me to the call log and calls random contacts fed up of this issue, its been only one month i have been using this mobile, also nit have installed any unsafe apps, constantly clearing the ram and cache too. Please let me know what is the permanent fix for the same.

    1. Hi there,

      This is somewhat similar to what I had faced on my OnePlus 5 after an Android Pie update. In my case, factory reset did resolve the problem. So, I suggest you the same.

    2. Please remove the animation and you will get rid of this problem. I did it and am fine now. Animation allows down the processor probably

    1. Hi Mathew, that seems to be hardware fault. So, you better reach out for the replacement from the manufacture. Before you do so, I would suggest you perform a factory reset and put it on charging again. Moreover, you can read our battery calibrate guide here:

      Let me know if that works for you!

  27. Hi,

Help out with this if anyone can.

    1. Hey, am also facing same issue. Getting irritate. I spoke with Samsung customer care, they suggested some actions, like factory reset, updating software, but not solved .. Still problem has not resolved.. pls suggest

      1. Hi Saran,

        This seems to more linked with the firmware. So, most probably, it should be wiped off in the next firmware update or you could ask service center to downgrade your device its very first native firmware.

  32. I just bought galaxy m20 about 20 days ago. The screen sometimes start working automatically and then it hangs. Oftenly i require to off the screen and then it become usable.

    1. Hi Girish, I see people are facing this problem a lot on this phone. There’s one that you could try, just enable the Developer Options on your phone and turn off the animations. This should probably solve the problem. For that you can follow this tutorial:

      I hope it helps you!

  33. I am using m20 for last one month … My problem is about charging … Usually the full charging requires 2.15 hour…But nowadays the fast changing didn’t working…It needs 4 hours to full charge …. What should I do ….

    1. Try calibrating the battery on your phone.

      Let your phone fully discharge. Once that happened, charge your to its full without turning it on. This should help.

    Thank you,

    I don’t think so fast charger take 3 long hours to fully charge. Plz help me regarding this issue
    Thank you

    1. Try performing a factory reset, if you that it doesn’t work. You can ask technical help from you Service center.

  38. Sir my Samsung M20 not charged fast even after 1 hour it’s increase 10 to 15%battery so please help me.

    Also I want to know that for how much time required for full battery charged in Samsung m20

    1. That seems be a problematic thing. Try to calibrate batter of your phone; drain the battery until your phone turns off. Thereafter, charge your phone’s battery to it highest level. Then again drain it. Thereafter, it should charge and work normally. If calibration doesn’t work, I would recommend you to seek technical help from from the service center.

  39. Why the typing probem apper while typing msg for a long time the all letter start click by itself plz samsung fix this plz

    1. Solution is pretty simple, just don’t any sort of third-party keyboard app. Even you can remove Samsung Keyboard app. The native Gboard is the best solution. Just download Gboard app from Google Play and make it default typing app on your phone.

  40. Dear Sir,

    i have purchased a M20 phone recently and both Volte calls and internet is not working

    when checked with Jio Sim in 1 slot and netvelocity it shows only 0.05mb download and 0.02 mb
    upload and calls are not maturing even after several times.

    how to solve this issue.

    1. Hi Samuel,

      Use the recovery mode to perform a factory reset. That should help you in fixing bootloops.

      1. How to do this.. I m facing same reboot issue repeating since 11th april to till now without any break.

  41. My M20 which i bought about two months ago has developed serious fast-charging issues after a recent update. When i bought for the first few times it was taking less than three hours to fully charge. but now after the update of about 80 mb recently, it is taking a full 10 hours to charge, wven as it is showing fast-charging connected.TEN HOURS !!!!!! this is ridiculous and absolutely unacceptable. I chatted with customer care, and they told me to trty charging it in “saef mode”…i tried that also , but even that has not helped. Otherwise there is no problem with the phone — the battery backup is solid, no heating issues or any other problems. but taking 10 hours to fully charge makes me feel i made a bad purchase. Is there a solution to it? am i the only one facing this problem or others also are facing it?

  42. Sir, My Samsung Galaxy M20 is not giving me fast charging, I’m charging it for the first time. Please help me. Is it my phone’s problem??

    1. Hi Suresh,

      This auto-touch issue seems to be common among these smartphones and this is somewhat related to firmware itself. Either you can installing this stock firmware again or switch to custom firmware.

  57. I have bought M20 three days back and had an issue in charging.After charging till 100% its draining to 25% within few hours without using atleast for 10 minutes. Plz say the solution to get out from it.

      The problem seems to be linked with usual work and stability. If you’ve been using this smartphone since 2-4 months, I would suggest you perform a factory reset and update to latest firmware (if any available).

      This will resolve your slow apps download from Google Play.

      2. Open Settings on your phone and tap on backup and reset menu. There you’ll find reset Network settings. Perform this action.

      This should solve the slow hotspot internet speed on your phone.

      I hope these solution help you. You’re free to share your thoughts and views on it.

  63. My mobile is not charging is showing that use proper charger for fast charging but iam using m20 charger and cable only.I went to service center they replaced usb cable but still its not working properly.Even the charger is removed still charging happens or cable got diconnected all the time.How to resolve this issue

    1. Hi Ashritha,

      The problem isn’t related to its charger or cable, problem is with the charging port. Seems that it has been damaged somehow. Again visit service center and report the same.

    1. Hi Ruchika,

      You better provide the exact error that you’re facing. If you’re unable to locate ringtone settings, then you can just open the Settings menu and use the search bar for that purpose.

  64. Bought Samsung m20 7 days back.
    Slow charge after charging to 70% and Charging sign won’t go even after switching of the switch unless unplugging the cable.

    1. That’s a hardware fault. The USB jack must’ve been damaged somehow. Visit the service center for better solution.

  65. Hi,

    I am using Samsung M20. During the calls there is an audio issue with sound being eaten up every 10 secs or so. So half the time, the conversations are not complete and have to be repeated. It is highly annoying since all the calls same problem. Updating software, restarting etc have been tried but didnt help. Otherwise there is no audio problem with videos, other audio clips or any other media.

    Can you help sort this out please

    1. Hi RJ,

      I remember I had encountered the somewhat same problem on Honor 8 and after I struggled a lot, the service center team reported that there’s a hardware fault. Phone’s (call) speaking isn’t working fine. So, I would recommend you to take advice from the service center.

    1. Hi there,

      This issue might be caused by the corrupt cache files. We recommend you to clear the cache on your phone.
