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

Samsung Galaxy A8 2018 was released in December 2017. Along with the Galaxy A8 2018, Samsung released the Galaxy A8 Plus 2018 as well. Samsung’s Galaxy A series is known to pull out smartphones with very good spec-sheet under a friendly budget. The Galaxy A8 2018 is just about that. With the new A8, Samsung has upgraded the design language of the A series. The phone now comes with an 18:9 aspect ratio sporting an infinity display which is quite similar to that of the S8’s.

Galaxy A8 2018 is running on the Exynos 7885 CPU. The Exynos 7885 CPU is designed for the mid-rangers. This CPU is backed by a RAM of 4GB. The internal storage is either 32GB or 64GB. Samsung is using a dual-camera setup on the front. There is a 16MP and an 8MP shooter on the front. At the back, Samsung is using a single 16MP shooter. Just below the single 16MP shooter, there is a fingerprint scanner. Samsung has installed the USB Type-C port for charging and connecting this phone to a computer. The headphone jack is there as well. Front and back of the phone are built out of glass and rounded by an Aluminium frame. Galaxy A8 2018 is protected by IP68 certification which means this phone is water and dust resistant.

As far as the display is concerned, the phone comes with a 5.6-inch full HD display. This is not an edge-to-edge display. However, the home button is gone from the phone making more room for the 18:9 aspect ratio. Galaxy A8 2018 is sleeker and it looks absolutely gorgeous. The phone runs on Android 7.1.1 Nougat out of the box. There is no doubt about the Android 8.0 Oreo update for this phone.

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 a 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 a new software manually on your phone using Odin. Here’s a guide to install stock ROM on your Galaxy A8 2018.

After checking the battery consumption having all apps disabled, you can start uninstalling the applications one by one to see which one improves the battery life.
  4. Sometimes, an old software can affect the battery consumption of 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.

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.

  1. Always use the original charger and the original data cable. If you do not have the original charger and cable, get an aftermarket charger and cable that is close to original.

  2. Check the electricity switch for electric current. There’s a great chance that the switch is malfunctioned and it is not providing required current to the charger. The phone can refuse to charge as a result of low voltage as well.
  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.

  1. Make sure that your phone’s battery is charged over 10%. Below 10%, the phones often refuse to take pictures. The battery below 10% will also not let your phone use the Flash.
  2. If the camera is taking poor-quality pictures, you can try using different modes to set the quality.
  3. In case the settings do not improve the picture quality, you can simple try clearing the data and cache of camera application. To do so, go to Settings > APPS > Camera > Storage > Clear Cache & Clear Data.
  4. Check if there is a Software Update available for your phone. A new update often fixes the bugs if there exist any.
  5. Try flashing a new ROM on your phone to bring in a brand new camera application.
  6. If the camera is not working, you can try using a third-party camera application from the Play Store to check if it’s really an application issue or it’s some hardware issue. In case it turns out to be a hardware issue, you will have to take your phone to the service center to claim its warranty to get it fixed.

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.
  6. If all the solutions listed above fail to work or you are facing any other kind of problem with the Bluetooth, you can go to Settings > About Phone > RESET > Reset network settings > RESET Settings. Restart your phone after resetting these settings.

WiFi Connectivity Problems

  2. Make sure that the router you are trying to connect is in the range of your WiFi.
  3. Make sure that the router is turned on and it’s internet connectivity is available.
  4. If you are unable to connect to an already added WiFi, you can go to WiFi settings under Connections and forget that particular network. Add that network from scratch once again.
  5. In case the solutions above do not work, you can reset the entire WiFi settings. To do so, you can go to Settings > About Phone > RESET > Reset network settings > RESET Settings. Restart your phone after resetting these settings.

Mobile Data Connectivity Problems

Mobile Data is not working? No problem. Have a look at these solutions:

  1. Flight mode should be disabled on your phone in order to connect to Mobile Data.
  2. Make sure that you have a working Data Bundle. In case your Data Bundle has come to an end, you will not be able to use Mobile Data.
  3. On your phone, go to Settings > Connections > Mobile networks > Network mode > set it to LTE/3G/2G (auto connect).
  4. The SIM card you are using should be in a working state. If you using a malfunctioned SIM card, you cannot use Mobile Data.
  5. To reset the entire network settings of the phone, go to Settings > About Phone > RESET > Reset network settings > RESET Settings. Restart your phone after resetting these settings.

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 in 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 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 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.

That’s all for now. I hope that you guys find these solutions helpful. In case I have missed something, or you have found another solution for one of the problems listed above, feel free to drop it in the comments section below.
