Problem 1: How to fix Galaxy S8 Plus black screen issue

I have a S8+ and the screen is completely black. The light at the stop left still works, I can hear the notification sounds, I can charge it, and I can swipe to answer calls. But I can’t see a thing. I have tried to do multiple resets, nothing worked. If I get the screen replaced, would that fix the issue? Help! Thank you. — Brossback09

Solution: Hi Brossback09. Since you’ve already tried resets, which we assume includes soft reset and factory reset, a black screen issue like this is can only be caused by a hardware malfunction or failure. Samsung displays are usually built with good quality but even top of the line displays can fail if the device is dropped or exposed to elements (heat or cold). If your phone has been physically impacted or sustained any form of hardware damage, forget about fixing the issue at your level. Unless you have the expertise and tools to do a screen replacement, you should let a professional repair the phone for you.

If, on the other hand, the phone was well taken care of and the monitor (the digitizer must still be working since you can swipe calls) just stops responding all of a sudden, there’s a chance that you may be able to fix the issue by doing some software troubleshooting. These are the quick tips that you can do to try and troubleshoot a possible screen issue:

  1. Make sure that your screen isn’t cracked, chipped, or damaged.
  2. If you have a case or screen protector, take it off.
  3. If you’re wearing gloves, take them off.
  4. If you’ve put any stickers over the screen or sensors, peel them off.
  5. Make sure that your screen is clean.

Check for possible third party app problem

Sometimes, bad third party apps can affect some Android functions and cause other features to work erratically. To see if a bad app is the cause, consider restarting the device to safe mode. While in this mode, all third party and services will not be allowed to load. If the screen will work fine in this mode, that’s a hint that an app is the reason for the trouble.

To restart the phone to safe mode, follow these steps:

  1. Turn the device off. If you can’t turn the phone off normally, wait until the battery has drained so the device will shut down on its own.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

Send the phone in

Should the monitor still stay black after doing the suggested steps above, contact Samsung and let them diagnose the issue. The least that could happen is a replacement of the monitor (the screen that shows images) so you want a trained professional do the job.

Problem 2: Samsung wireless charger won’t work with iPhone

Hi. I recently purchased a Samsung fast wireless charging dock to use with my iPhone 6s+, and it has been working brilliantly (along with the charging coil patch I attached) up until I placed an actual samsung phone on the dock. I’m sure the problem is related to this incidence because I removed my phone (which was charging as I removed it) and placed my friends samsung on the dock to show it off (it worked with the Samsung). I then replaced my phone on the dock and for the first time I saw the indicator light, which normally turns on and is blue, blink green once, and then turn off. The indicator light no longer turns on when my iPhone is placed on the dock, it won’t even recognize that my phone is there. It continues to work well with the Samsung. Is there a way to fix this problem, or should I return the dock and repurchase? (Not the ideal solution) thanks for your help. — Mzfarhangkha

Solution: Hi Mzfarhangkha. Just as not all cable chargers work with other devices, wireless chargers are also not built universally. Samsung wireless chargers are built to cater to particular specifications of a Samsung device only. It’s not advisable to use your Samsung wireless charger to charge a non-Samsung device as the specifications for that device may be different. This means that a Samsung wireless charger is only validated to work with particular Samsung models (not even all Samsung phones) and using it with a non-Samsung device may lead to problems. Chargers vary by a few important aspects but most importantly by the amount of voltage and current that they provide to a device being charged. If you use a charger with a different specification with your iPhone, you’ll most likely damage the battery or power IC of your device. If you want to wirelessly charge your iPhone, do it with devices that Apple has certified to work with your particular model. This article is a good starting point if you want to research more about this topic.

Problem 3: Galaxy S8 fast cable charge not working

I bought a S8 from my friend. It appears to be from UAE/Egypt. I had no problems from the last 6 months except that I had to forcefully push the charging pin to get the Fast charging to enable. The other day, the phone refused to charge from the original cable and adapter. I used the B to C type charger adapter which comes in the box. Now the phone is on slow charging when I use this adapter. I wonder if the charging port is bent. And if I take this to a service center, how much would they charge me? And what would’ve caused this problem? Please advise. Thanks. — Biju

Solution: Hi Biju. Fast cable charging is supposed to work without applying pressure in the charging port. If you need to do this before, then your phone must have a bad charging port. To fix the issue, the charging port must be replaced. We don’t know exactly what’s the real deal but yes, a bent or shorted metallic contact in the port can cause this problem.

As to the cost of the repair, exact fees vary depending on the issue and the service center you bring it to. Samsung devices have a standard 1-year manufacturer warranty so we believe the device is still covered by it. Unless you or the previous owner did something that may have voided the manufacturer’s warranty which includes the following (although not limited to) such as tamper with the software, scratched the phone, or physically damaged the phone, or attempt to take the phone apart, we suggest that you let Samsung fix it. If the phone is deemed out of warranty by Samsung, they may still repair it for a fee. For a device like this, an ordinary repair may cost about $200, more if there’s an expensive component that needs replacement like a broken motherboard. A third party repair should cost more or less that of Samsung service center charge.

If you don’t want to go through a repair, you can try the phone’s fast wireless charging with the use of a fast charger. This charger is usually part of the accessories that came with the box so ask your friend for it if he still has it.

Problem 4: Galaxy S8 update issues, Facebook issue after installing Android update

Hello there. I’ve got the Samsung Galaxy S8 which I only purchased a few months ago. All was well until I updated the system and since then have had problems across the board. Firstly, when videos are playing on Facebook they go between extremely blurry to focused constantly. I’ve reported problems to App but nothing has changed.

Secondly, I now cannot open attachments from the internet on my phone. I can do this via email apps but when on Internet or even using Chrome when I am on my banking or energy accounts, I try to download Word or PDF attachment, it opens a new tab which immediately closes. I’m very frustrated! Any help would be appreciated. Thanks. — Claire

Solution: Hi Claire. Post update issues are usually addressed by two software solutions — cache partition wipe and factory reset. If you haven’t tried them yet, below are the steps on how to do each of them.

Galaxy S8 cache partition wipe

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key to highlight wipe cache partition.
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Galaxy S8 factory reset

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until Yes — delete all user data is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Install app updates

If any of these two solutions won’t fix the problems you mention, make sure that ALL your apps are up-to-date. Keep in mind that installing an Android update does not mean apps are automatically updated too. If you have a poorly coded app installed, or if an incompatible one exists in the system (may happen after the operating system is updated), problems can occur. If you’ve already updated all your apps after installing the latest Android version, you can also check if the issues will occur when the phone is in safe mode. Refer to our suggestion for Brossback09 above on how to do it.
