6. Fix Slow performance and unstable Android interface

No matter whether you’re using a low budget mobile phone or something killer like Galaxy S10, you can’t say that its performance remains rock solid all the time. There are many factors that bring negative impacts on our phone throughout the time we use it. The possible issue that you would face over time with any phone is somewhat related to performance and stability.

And to sustain performance, there are some cleaning actions that we should perform oftentimes. Even we can implement some tips and tricks to enhance the overall performance and stability. Here are some recommendations that you can follow to improve performance on your Samsung Galaxy S10:

  1. We should start with cleaning action. The Samsung smartphones have been blessed with inbuilt cleaning option that is available within the ‘Storage’ menu. Performing this action will remove clutter and expire data. That will instantly bump up performance and stability on your phone. Just open the Setting -> Storage and then tap on ‘Clear Now’.
  2. To deep clean your phone, we suggest you use the recovery mode and perform ‘Wipe cache partition’ action. This will clean every bit of cached data, associated with both system and third-party apps. We have already mentioned steps above many times.
  3. Furthermore, if you’ve been using your phone for a long, your phone deserves a factory reset. That removes everything, whether it is app, download, or cache. To factory reset your phone, just follow the below steps:
    1. Open the Settings’ menu on your phone.

    3. Now, tap on ‘Reset‘.
    4. Then, tap on ‘Factory data reset
    5. Then, scroll down to the bottom and tap on RESET->DELETE ALL.
  4. Remove unwanted apps from your phone. Samsung bloats their smartphones with plenty of apps; of course, many of them are useful, however a plethora of apps that remain unused throughout the time. And many of these unused apps, utilize processing power, and Internet in the background. Thus, removing or disabling unwanted apps should bring positive results. While working for Note 9, we found 120+ bloatware apps were there and after we disabled then, we find 1.5 GB (approx.) was released. Considering this amount, we should take care of the extra or ordinary apps present on our phone.
  5. Switching from Samsung’s native launcher to Nova Launcher or Google Launcher can help you achieve better performance. These third-party launchers have been specifically built for better performance and faster actions. We have a list of theme launchers that you can choose from. This way you can customize your phone beautifully while speeding up actions.
  6. Further, we suggest reducing the extent and duration of the animations on your phone. Yes, you heard it right and you can set then accordingly on your phone. Just follow this tutorial to learn about the Developer options and how to use it to customize animations for better performance.

For more useful tips and tricks to speed your phone, must follow this tutorial here. These tips should be enough to squeeze out some extra performance on this phone.

7. Poor battery life on Samsung Galaxy S10 and S10 Plus

Being a high-end smartphone, it should last all day long when used normally. If you suspect that battery discharges quickly, there can be different reasons for that. There might an application (or more apps) sucking battery on your phone or the recent update has brought this instability on this phone. Whatever be the reason, you don’t have to worry much.

It won’t take your much time to troubleshoot quick battery drain problem on your Samsung Galaxy S10 smartphone. Just follow the below recommendations for that purpose.

  1. First of all, we recommend you to disable or uninstall all unused and unwanted apps from your phone. That will free a good amount of RAM and storage space while impacting the battery life positively.
  2. You should observe your phone to figure out what consuming the battery power most. You can do so using the Developer Options. Within this menu, tap on the ‘Running services’ entity and get detailed information about running services. There you can easily locate the culprit ones. Simply, just disable them or remove them completely from your phone.
  3. If you’ve recently updated your phone and it resulted in this problem, then you should perform some cleaning actions. You can clear the entire cache files on your phone. Just get into the recovery mode on your phone (resource give above) and perform ‘Wipe cache partition’. This action improves both; performance and stability.
  4. For a dramatic drop in battery life, a factory reset is highly recommended. Over time or due to certain apps or after an update, the Android firmware might have been affected and that’s causing quick battery drain problem on this phone. In such cases, a factory reset is fruitful.
  5. Further, you should optime your phone for better battery life. Go to Settings > Battery > Battery Usage > More > Optimise battery usage, and tap ‘All Apps’. That will restrict the apps from using the battery carelessly.
  6. Further, we recommend using lite versions of the Facebook app and its messenger. These two apps consume a lot of battery life while the user is indulged with them or not, they work in the background as well.

These solutions should be enough to overcome quick drain problem on your Samsung Galaxy S10. Moreover, you can follow our dedicated guide for this purpose.

8. Unexpectedly shut down and reboot problems

Such problems usually happen due to clutter and expired data that gather after a while. The cache files are generated by the applications that we have on our phone. After a certain time, they become unnecessary and until we manually remove them, they keep stored within the phone.

They cause different problems related to performance and stability. Therefore, through some cleaning actions, these should be removed.

  1. You should observe your phone thoroughly. There might be an application stopping your phone to run normally. If you’ve recently installed applications (or more apps), you better try removing them to see if that resolves this problem on your phone.
  2. Check your downloads folder and remove the recent stuff that you’ve downloaded. Though Android OS is quite secure, still malware or similar thing could hurt performance and other aspects on your phone.
  3. If the above solutions don’t make any change, you can perform ‘wipe cache partition’ action to remove clutter and cache data on your phone. Most probably, this action should work to resolve random reboots problem on your Samsung Galaxy S10 and S10 Plus smartphones.
  4. Further, you can perform a factory reset to restore original aspects and settings on your phone. Before you do so, ensure that you create a general backup on your phone.
  5. If there’s something bad with the Android firmware, then you would need to restore the stock firmware on your phone.

9. Low Speaker Volume on Galaxy S10 and S10 Plus

If you’re facing such a problem on your phone, then there can be two reasons: either the issue is with phone’s speaker or the media file that you’re playing has low output volume. Although, sometimes it could happen due to some issues on our phone. We have the following troubleshooting solutions to cure such problems:

  1. If you find that Speaker volume is unusually low, then have a good look around the speaker area. There are chances that some dust over that is resisting the full volume. Use a pointing pin carefully and clean that area. Do this very carefully, or else you might end up messing up things. **This action could physically damage the speaker. So, do it carefully.
  2. Few times, these problems occur right after we update our phone. During an update procedure, the cache and clutter files are corrupted that causes such problems. To resolve it, we recommend you to perform one of these solutions; either clear the entire cache partition or perform a factory reset. Performing a factory reset is more helpful in such issues.
  3. And if you figure that the problem is associated with the media file, then one can use third-party apps to boost the outcome volume. There’s an application named ‘Speaker Boost’, this app works amazingly. You can read out tutorial; how to boost volume on Samsung Galaxy smartphones.

These are the available solutions to fix such problem. If you suspect that this issue is related to hardware, you better reach out to the service center.

10. Network issues on calls on Samsung Galaxy S10 and S10 Plus

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 wrong placement of the SIM card. That should bring some improvements to the network signals.

  3. If that has happened after an update process, you better perform a hard reset on your phone. That should fix all the problems on your phone.
  4. If nothing works, better reach out to the SIM Card operator.

11. Accidental screen touch from side

Being a bezel-less smartphone, it obvious to expect no space insides while holding this smartphone. That surely leads to accidental screen touch that could open app, settings or just wake up the screen. While there’s nothing you could do about if you’re using the edge panel, you would need to disable that to avoid this problem.

Thought edge panel looks good, however, you can get tried with an accidental touch problem on your Samsung Galaxy S10, S10E and S10 Plus. If you wish to solve this problem, either you can disable the Edge panel or at least enable ‘Accidental Touch Protection’ option to avoid accidental touches while the phone is in pocket or bag.

12. Troubleshoot Apps that are not full screen or support split screen

Though Android OS has been developed so much, still there are many applications that do not support a full screen and split screen feature. While there’s nothing you can do directly to those applications, Samsung Galaxy S10 does offer several options to tackle such issues. We have separate options to fix these issues on Samsung Galaxy S10 smartphones.

Basically, some applications/games are not capable of going full screen on smartphones having high screen resolution. Since Galaxy S10 and other variants have impressively dense screen resolution, there are more chances for you to face such problems. Thus, this guide shall help you fix these problems on your phone. Here’s how you can fix apps that are not full screen:

  • Open Settings on your phone.
  • There tap on Display.
  • Now, tap on Full-screen apps.
  • And then, select the full-screen option for apps that are not full screen.
  • Exit these settings.

After that, those applications should use the full screen to work. This option works most of the time. Rarely, you might find such problems.

Now, if you find that certain app or game isn’t working in the Split mode, there’s a cure for that. The Developer Options, a hidden menu on Android phones, offers an option to fix this problem. Here’s how you can fix apps that do not work in split mode:

  1. Enable Developer Options on your phone.
  2. Open Settings and tap on Developer Options menu.
  3. Under this menu, locate ‘Force activities to be re-sizable.
  4. Enable this option and exit this menu.

Now, going forward, all apps should support split mode on your phone. And there’s should be any further problem. If you don’t find above method working, make sure to reboot your phone.

13. How to Fix Ultrasonic fingerprint is not working on Samsung Galaxy S10

Do you find yourself struggled with an ultrasonic fingerprint on your phone? Many users have reported different issues related to this fingerprint feature on Reddit and many other boards. You might problems like fingerprint wouldn’t respond to your requests or it might get freezes and does nothing.

The most common problem reported is that, while fingerprint scanner works smoothly in a row, suddenly it doesn’t respond to 3-4 attempts and thereafter it becomes normal. It misses some attempts. If you’re facing such issues, here are some recommendations that you can follow:

  1. First, we suggest you reboot your phone. Just a reboot fixes many problems, if fingerprint scanner isn’t working due to minor bugs, this should probably fix it.
  2. Ensure that your phone has updated to the latest version. If there’s any pending update, you must install that. Updates, minor or major, bring fixes and improvements to many known bugs and problems.
  3. Next, we suggest you remove the existing Fingerprints on your phone. Just open Settings on your phone, and open Fingerprint settings. Remove the existing ones and reform it. That probably should fix fingerprint doesn’t work problem.
  4. While adding a new fingerprint, ensure that you put the finger properly on the scanner. That’s the correct way of storing fingerprints.

Lastly, if you don’t find any solution work, perhaps this problem is linked to firmware itself. Thus, you would need to wait till Samsung brings further updates.

14. Troubleshoot Proximity sensor doesn’t work during call on Samsung Galaxy S10

This problem is among most annoying ones. No matter if you’re having an iPhone or this flagship phone, Samsung Galaxy S10, this problem can happen due unknown reasons. This problem can be related to the hardware part or there’s something isn’t correct with the firmware. What so ever be the reason, we gotta troubleshoot this problem somehow.

If this problem caused because of hardware aspects, you must visit the service center, either ask for the repair or replacement as per your convenience. Before you do that, here are some recommendations that you could apply:

  1. Ensure that there’s no transparent film over the proximity sensor on your phone. This could happen if you’ve recently purchased this mobile phone. So, check properly that there’s no film over this sensor.
  2. Next, you must keep this sensor clean. Sometimes it happens that moisture and dust gather over it. That can restrict it from being functioning correctly. You can use a soft cloth to clean it thoroughly.
  3. If you’re using a case cover or something like that, make sure that you’re using a fully compatible one. It must have dedicated holes for buttons and sensors.
  4. Sometimes, such issues happen due to firmware bugs. So, you must update your phone to its latest firmware. You shouldn’t miss those updates. You can check for the latest updates here; Settings->About Phone-> Update. If there’s any pending update, you must install it.
  5. Further, if you don’t find any sign of improvement, you can perform wipe its cache memory. This action helps to fix most of the bugs and problems that usually happen on Android smartphones. Use the recovery mode to wipe its cache partition.

These are the troubleshooting actions that you can take to fix Proximity sensor on your phone that doesn’t work.

15. What to when Screen is black but phone is powered on Samsung Galaxy S10

Again, it is among the most annoying situations. If that happens to you, you won’t be able to use your phone until the screen wakes up. This could happen due to faulty applications, settings or the Android firmware itself might get crashed. This can happen randomly and that’s hard to figure out the exact reason caused this problem.

Here are some useful fixes that you apply if your Samsung Galaxy S10 isn’t working as expected:

  1. Force reboot, probably this action is going to help you a lot. Since the only display isn’t working, the rest of the features seem to work, there might be a real-time bug causing this problem. Just press and hold the Power Off button till it vibrates and reboots.
  2. Next, you should observe whether this problem persists in Safe Mode or not. Basically, when Safe Mode booted, all third-party apps and settings become invalid and they won’t work. Thus, if there’s any third-party app or service causing this problem, your phone should work normally within the Safe Mode. Here’s how you can boot into the Safe Mode:
    1. Turn OFF your phone using the Power key.
    2. Press and hold the Power button.
    3. Once, the Samsung logo appears, release the Power key and now quickly press and hold the Volume Down Key.
    4. Continue holding the Volume down Key until the phone finishes rebooting.
    5. After seeing the “Safe mode” at the bottom left corner of the screen you need to release the Volume Down Key.
  3. If that doesn’t solve the problem, you can go ahead and wipe its cache partition. This will remove all cache files on your phone. Again make use of the Recovery Mode.

    My Samsung S 10 plus is doing problem in last 2 days whenever m using video call, my video calling screen itself minimizes after few seconds, and I have to maximize it manually again and again it’s very annoying for me to do so.. The error occurring in whatsapp video call, messenger video call, insta video call and google duo.. I have tried reset settings and also restarted my phone but my problems remains the same

    1. Hi Manjeet,

      Since this problem happens on different video calling apps, most probably, this problem is caused by a third-party applications. Try removing third-party apps on your phone. This should help you resolve this problem.

  8. Hello sir..
    My Samsung s10 plus gives me a problem wheal i turn on the Internet,
    It get hanged and m not able to do with my phone anything sir…so i need to turn it off back..

    1. The problem is somehow related to firmware. I would suggest you clear its cache files or perform a factory reset if that doesn’t work.

  9. When using mic to “talk to text” in messaging, I have to touch the mic 5 or 6 times before I can use it. It says “unexpected error, retry later”

    1. Hi Mo,

      Just open the Apps manager and locate this Talk to Text app, then tap on storage section. There, clear its cache memory. That should fix this problem on your phone.

  10. I’m having trouble getting my screen to open when tapping it. I can’t get to where I need to put in my pass-code. I do have a screen saver on but, even after removing it, it still doesn’t open. This is a new problem, only about 2 weeks now, as prior to this time it was fine. I’m concerned that I may not be able to call the emergency services should I have a problem when I am out walking in the early morning. It’s extremely frustrating! Do you have any suggestions/solutions?

    1. Hi Jane,

      I would suggest you boot this phone into the Safe Mode to see if this problem exists. There might a third-party app (or preinstalled app) causing this problem.

      If you find that everything works fine in the Safe Mode, you would need to figure out the culprite app on your own. That must from the recent ones that you’ve installed.

      To boot into the Safe Mode, just press and hold the Power button, that should bring Power Menu. Now press and hold Power Off option. This will bring a Safe Mode option in front. Just tap it to reboot your phone into this mode.

      There, observe your phone. Let us know if you further face any problem.

  11. I am having issues with “can’t screenshot due to security reasons.”

    How do I correct this? Never had this problem using galaxy s7edge.

  12. I have SAMSUNG S10+ smart phone. I have screen lock using a password. Last few days I have screen unlocking issue. Screen remains unstable and will not allow me to type my password to unlock.

    1. Hi Shasikant,

      This problem is related to OS itself. To resolve it, you would need to enter into the recovery mode and wipe the cache partition. This should help you get over this problem.

  13. SOLUTION TO SIGNAL PROBLEM (I have T-mobile 4g LTE): dial *#2263# and select CLEAR ALL BANDS .. then go to LTE Band Preference and [NEXT PAGE] then select LTE B71 .. go back and APPLY BAND CONFIGURATION … that is what personally worked for me and took me forever to figure out .. if that doesn’t work for you then clear all bands and only select 1 band at a time and literally go thru all of them to see which has the best signal .. if you want to go back to original settings then just select all bands and apply configuration .. good luck to you all <3
