Galaxy A8 2018 Common Problems and Fixes: Battery, Performance, WiFi, Bluetooth, Camera & More

Performance Issues

The most annoying problem a smartphone user faces is the sluggish performance. If a phone, that you just bought after paying the hard-earned money, starts lacking, it definitely makes you cringe. Fortunately, the Performance Problems are not such a big deal as you can always fix them (as long as it’s about the software of the phone). There are various solutions that can solve the performance problems of your new A8 2018.

1.  Clear the cache of your phone

Clearing the cache of your phone is like one medicine for 100 different diseases. Once you clear the cache of the phone, it refreshes everything and gives your phone a new start. It’s very easy to clear the cache, just follow the steps below.

1. Turn off your phone completely.
2. Now turn on the phone by pressing and holding Volume Up + Volume Down + Power button.
3. As soon as your phone shows a screen with some options, follow the on-screen instructions to get into the recovery mode.
4. In the recovery mode, use Volume Up and Volume Down keys to navigate to “Clear cache data” and then press the Power key to make a selection.
5. Clear the cache now and reboot your phone. Check the performance after rebooting the phone.

2. Boot your phone in Safe Mode

Booting up your phone in Safe Mode disables all the applications on the phone. This is a method to check if a particular application that you recently installed is behind the slow performance of your phone. If the phone performs better after booting up in Safe Mode, it will mean that there is an application slowing down your phone. In such a case, you can start deleting your recent installations one by one to identify what makes the performance better. Here’s how to do this.

1. Turn off your phone completely.
2. Now turn on your phone. As soon as the Samsung logo appears on screen, press the Volume Down key and keep it pressed until the phone takes you to the home screen.
3. You will now see a “Safe mode” watermark on the lower left corner of the screen. All apps will be disabled now.
4. Check the performance of your phone now and fix it.

3. Uninstall unnecessary applications

Having too many unnecessary applications can pull down the performance of the phone. If you have a pile of applications that you absolutely do not touch, it’s time to uninstall them. This will potentially improve the performance of your new Galaxy A8.

4. Check for Software Updates

Go to Settings > Software update > Download updates manually > check if there’s an update available. If there is one, update your phone right away. Running your phone on an older version of Android can cause the issue.

Heating Up Issues

The solutions given above to fix the performance issues of the phone will work for fixing the heating up problems as well. There are many reasons for a phone to heat up. The games that consume most of the CPU, clock the GPU at its max and also give a bull-run to the RAM can heat up the phone. You have to identify an application that’s causing trouble, or you just have to give your phone a refresh to cool it down. Here is what you can do to fix it up.

1. Clear the cache of your phone to restart all the process on your phone. A stuck process can heat up your phone. Clearing the cache will refresh everything by starting it from scratch.
2. Reboot your phone in the Safe Mode to check if an application is adding to the temperature of the device. You can follow the method given above for booting into the Safe Mode.
3. If the phone heats up the most while playing a resource-intensive game, you need to uninstall that game right away before it kills your phone.
4. Sometimes, an old software can start heating up your phone as well. You can check for updates and install a new update if there is one available.
5. If the above issues fail to work for you, it’s time for you to factory reset your phone. You can do so by booting into the recovery mode.
6. If the factory reset also fails, you can choose to flash new software manually on your phone using Odin. Here’s a guide to install stock ROM on your Galaxy A8 2018.

Charging Problems

Your phone is not charging at a speed it is supposed to charge? or it is just refusing to charge? Here’s what you can do in this case.

3. Check the phone’s charging port. Clear out any smut or dirt using a Qtip from the charging port.
   

4. Charging your phone in a car or using a power bank will not give you the same results as that of an electric switch. While charging in a car or using a portable charger, keep in mind that the charging time will only increase.
   

5. Charging you phone using the laptop will also take a lot of time.

Camera Problems

Somethings gone wrong with the camera on the Galaxy A8 2018? Is the Camera taking poor-quality pictures? or the Camera is just refusing to take pictures? Here are the solutions to fix all such problems.

Bluetooth Connectivity Problems

Bluetooth connectivity, visibility and pairing issues? Here are the solutions.

1. First of all, make sure that the Bluetooth isn’t turned off. If you recently enabled flight mode, it can also turn off Bluetooth. Although Bluetooth can be easily enabled while the flight mode is on, the flight mode just turns it off when you enable it for the first time.
2. Always make sure that your device is discover-able by other devices. Go to Settings > Connections > Phone visibility > Turn it on.
3. If your phone is unable to pair a specific device, you need to check the visibility and connectivity of the 2nd device.
4. If the phone still refused to pair, you can try restarting your phone.
5. Having difficulty connecting to an already paired device? You can remove that device from paired devices and connect it again.

SIM Card & Related Problems

In case your phone is not detecting the SIM card, you need to check if your SIM card is properly inserted or not. Apart from verifying the SIM card placement in the phone, you also need to check if it’s in the working form. Always make sure that the flight mode is disabled as it can stop your SIM card from working.

Mic Problems

There are two mics on the phone. One at the top and one at the bottom. The bottom one works when you are talking on a call while the top one works either for noise cancellation or when you are using the phone on the speaker mode. The top mic also works for recording videos and recording audio. You can try cleaning both these mics using a brush or a small pin. There can be a spot of dirt covering up the mic hindering the outgoing voice.

Speaker Problems

Use a pin to clean the speakers of the phone if the voice coming out is not clear. Also, make sure that the audio you are trying to listen is of high quality. If the speaker is having issues during a call, it may be possible that the other person has issues in his/her mic.

Galaxy A8 2018 Not Detected By PC / USB Not Recognized Error & Other Related Problems

When you connect your phone to your computer for the first time, it doesn’t show any contents. In order to show the contents of the phone in your computer, you have to allow the phone to connect to PC first. After connecting your phone to the computer, unlock the phone and tap the Allow button appearing on the screen to connect it as a USB Storage.

At times, the PC fails to recognize the phone as a result of a faulty driver. Always update the drivers on your phone. Make sure that you have installed Samsung USB drivers prior to connecting your phone to the PC. You also need to use the OEM data cable to establish the connection.
