Common Problems and its Solutions

1. Slow and sluggish performance

Solution 1: Do the forced restart

The reason why your phone is so slow might be caused by a minor firmware issue or glitch and they can easily be fixed with a forced restart.

What’s more?

It is pretty easy and very effective.  You just need to simultaneously press and hold the power and the volume down button and you’ll get it from there.

If it’s still slow and sluggish, let’s get to the next step.

Solution 2: Run the device on safe mode

No! Not “this” safe mode!

If the problem is not caused by the firmware, it might be caused by some third-party apps you might have installed. Booting in safe mode will disable all extra apps you might have installed.

This means that if your phone is working properly in the aftermath, then you know where the problem lies.

Couldn’t get any easier than that right?

If your device works properly at this point in time, you should uninstall all the apps you added when your phone started to get slow.

Solution 3: Reset Settings

If the problem still persists even though you’ve done the first two solutions, then you might need to reset your phone’s settings.

Trust me, it doesn’t sound bad as you think it is.

It will only set your phone’s setting as when it first came out of the box.

Solution 4: Wipe Cache Partition

Keep your cache clear!

If the previous solutions don’t work, then your cache files might have been corrupted. The cache partition actually helps in making your phone run smoothly, but it gets corrupted, performance issues will begin to pester you.

Sounds nasty, right?

All they need is a little bit of cleaning by clearing the cache partition through the Recover Mode.

We hope that it fixes the problem!

2. Heating Problem

Is your phone too hot to handle?

To solve heating issues, you must first need to understand what’s causing them in the first place.

And you know what?

It is the hardware component of your device.

They are the processor, ram, battery, and screen. You need to understand that using your device means using these components and will result in heat.

Now that you have an idea, let’s get down to business.

Solution 5: Uninstall unnecessary apps and games

Stop gaming every chance you get!

Installing many unnecessary apps and games will make your phone heat up like a freshly shot cannonball. This is because some of these apps will continue running even though you have terminated the app.

This is because some of these apps use your WiFi or data in the background.

Besides, gaming for an extended period will exhaust your hardware components and will cause your device to break early due to all the heat it creates. To address this, uninstall games that you rarely use anymore and instead of playing for long hours, better break it down into segments so your phone has time to cool down.

Solution 6: Observe proper charging

Don’t use your phone while charging.

Are you using a replacement charger?

If so, you might want to check the specifications of your new charger and see if it fits the specifications and power rating intended for the Galaxy A10.

You don’t also want to use your phone when charging as this will make excessive heat that might cause damages to your phone’s precious components.

3. Poor battery life

Your phone should last a day without charing

Your battery might be the single most important part of your device while others might argue that it’s the processor or the RAM.

But guess what?

What would the processor and the RAM do when they don’t have the power that the battery provides?

Get it?

That’s why you need to protect the battery at all costs and here’s what you can do if you’re struggling with your quick depleting battery.

Solution 7: Avoid Using Live Wallpapers

Live wallpapers refer to those fancy wallpapers that move or those you can interact with. This means that they will move accordingly with certain gestures you perform on the screen.

This type of wallpapers consumes a lot of battery resulting in more frequent charging.

And what’s more?

Frequent charging means more heat; and more heat means poorer battery health.

Solution 8: Manage your apps wisely

Uninstall all those bloatware.

Ever wondered what those apps that you hardly use are?

Fact: almost ever phones or devices have them.

They are called bloatware. These are applications that you don’t really use but manufacturers put them in your device anyway. Aside from eating a lot of precious storage spaces, some also perform functions in the background on certain conditions; like being connected to the internet, for example—and they consume lots of battery juices!

To combat these, make sure to identify, disable, or even uninstall these apps if you can. If you can’t remove them, just make sure that you don’t ever allow them to run on the background.

Check this out on your phone’s Settings under the Applications category.

4. Malfunctioning Touch Screen

Perhaps you need a softer touch?

A malfunctioning touch screen is like a needle in your toilet seat: it’s a pain in the butt!

So we understand if your screen suddenly malfunctions. Trust us; been there, done that.

Try these solutions below to quickly get back on track.

Solution 9: Clean your Screen

This is the most obvious troubleshooting step ever and it is so simple—just clean your screen!


Because your phone has a capacitive touch screen. Meaning, they need to sense electrostatic conductions to work. Needless to say, dirt and grime will disrupt the flow of electric current between your fingers and screen rendering it unable to work properly.

What’s more?

Choose your cleaning substance carefully.

You also need to make sure that the screen of your Galaxy A20 is kept as dry as possible. This includes body sweat, oil, and grease. This is also especially true when droplets of water made contact with your screen: you’ll notice that there would be ghost touch everywhere!

So always keep your phone clean and dry!

Tip: While you’re at it, check your glass screen protector if you have one and see if it’s installed correctly. This might be one of the causes of the malfunction.

If it doesn’t work, then proceed to the next solution.

Solution 10: Clean your cache partition

Keep trash out of your phone.

That malfunctioning screen is really pesky, isn’t it?

It might be caused by an overload of corrupt system files!

Sounds nasty, right?

To fix this, you need to clear the cache partition of your phone.

Just enter recovery mode, navigate to the “clear cache partition” option and you’ll get it from there!

Easy, peasy!

Solution 11: Perform a diagnostic test

Still not satisfied?

Thankfully, Samsung allows you to figure out which part of your Galaxy A20’s screen that is not working.

To do this, you need to launch the diagnostic tool.

Just dial *#7353# and select TSP Dot Mode/TSP Grid Mode.

It’s not like searching for the cure for cancer!

The TSP Dot Mode will display a pattern of dots on the screen. On the other hand, TSP Grid Mode enables you to test individual sectors of your screen overlay.

This will help you see if there is something wrong with your touchscreen or not.

And it’s not that even hard!

5. WiFi Issues

One of the most common problems when it comes to using a smartphone is WiFi problems.

But worry not.

All you have to do is restart your router. Turn it off and keep it off for a minute or two. Hopefully, when you turn it back on again, your problems are now solved.

This is because even devices need to be refreshed to work properly. Additionally, you could try this with your device as well: Just deactivate and activate the Galaxy A20’s WiFi function and then ‘refresh’ and try searching again.

Just make sure that you have the “Mobile Hotspot” feature on, then you’ll have no trouble or anything.

But what will you do if there is indeed trouble?

Here are some solutions.

Solution 14: Connect to the internet

Try testing your connection with an SNS App.

Other phones can’t surf the internet while they are connected to you?

Did YOU try browsing the internet yourself? When other devices couldn’t connect to the internet, chances are the hotspot itself couldn’t connect to the internet.

You might have missed it but you might have weak reception or you might have totally consumed all your data!

If you’re a postpaid user/plan holder, you may have problems on your accounts and if you’re a prepaid consumer, make sure that you have enough credits to connect to the internet.

Either way, just make sure to check your account as your problem is probably in that area.

If it’s not the problem, proceed to the next solution.

Solution 15: Do a soft restart

You don’t have to throw your phone away!

Sometimes, the issue stems from a software glitch in your Galaxy A20 and soft restart will solve this problem.

To do this, just press and hold the power button and the volume down button altogether and wait for the device to restart.

After doing this, you make another attempt on connecting to the internet and hopefully, there should no longer be any signs of the problem!

If the problem still persists, then on to the next solution!

Solution 16: Reset Network Setting

If the previous remedies still didn’t the problem, then you might just need to reset your Galaxy A20’s Network Settings.

Don’t worry, it’s not that hard.

  • Just go to General Management on your Settings and tap ‘Reset.’
  • Then you need to touch ‘Reset Network Settings’
  • Enter your PIN, Password, or Pattern if prompted and confirm to reset.
  • If everything is done, test if your phone can now connect to the internet.

Hopefully, this fixes all your problems!

Solution 17: Boot in Safe Mode

Better safe than sorry!

When it comes to firmware issues, one of the first steps of troubleshooting is to boot your device in safe mode. This is because Safe Mode will temporarily disable all third-party apps and will only run with the bare minimum.

If your device seems fine in this mode, then you can conclude that some apps that you might have installed are the culprit of all your problems.

Solution 18: Update your phone

That constant turning on and off might have been caused by a bad firmware.

Check if there’s an OTA update that you might have missed for your Samsung Galaxy A20.

When it comes to this, if there’s plenty of users experiencing the same problem, chances are the manufacturer (Samsung) will deploy an update that will fix this.

If not, then it all boils down to the next step.
