Problem 1: Galaxy S6 heats up during wireless charging, keyboard app lags randomly

I have a Galaxy S6 model SM-G920T. I charge it on a Samsung model EP-PG9201 wireless charger. The charging has worked fine since I’ve had this setup, maybe 2 years?

In the last couple of days, the phone has been hot after taking it off the charger. After a short time, it cools down to normal.

Also, and I don’t know if it’s related, there was a software update back in July and a couple more following that. Since then, I’ve noticed that sometimes the texting keyboard gets so slow, I have to restart the phone. And I’ve never needed to do that.

Also, there’s a kids Bible story app that now randomly speeds up the narrator’s audio. I appreciate any help. I’m afraid if I go to T-Mobile, they’ll point a new phone. Thank you. — Randy Krauss

Solution: Hi Randy. While charging whether via USB cable or wireless charger, it’s normal to observe the phone getting warm, like when you take a fresh toast from a toaster. However, if your phone becomes uncomfortably hot, that can be an indication that there’s something wrong with the hardware. The usual culprit for this unnatural charging behavior can be a bad battery but it can also be another component in the motherboard. To see if you can limit the heat generated while charging via software, kindly do the following steps:

  1. Open Settings app.
  2. Tap Device management.
  3. Tap Battery.
  4. Tap More settings at the upper right-hand side (the three-dot icon).
  5. Tap Advanced settings.
  6. Move the slider to the left for Fast cable charging and/or Fast wireless charging.

If the phone continues to heat up beyond normal, that should suggest a hardware issue. You must have it checked by Samsung or by your carrier.

For the rest of your issues about random keyboard app lag and abnormal behavior of an audio app, we suggest that you try to delete an app cache and data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more.
  5. These are all clickable items. You’ll want to click on Storage.
  6. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Sometimes, many Android users forget that installing Android updates does not automatically update apps as well. Make sure that ALL your apps are compatible and that all of them are up-to-date. This is especially important if you turned off automatic updates in Play Store app.

If nothing appears to work after installing app updates, or if you’ve already updated everything before contacting us, we suggest that you try a factory reset to fix the app issues.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

Problem 2: Galaxy S6 won’t turn on after updating

Last night I set the automatic update for 10pm, set the phone on the charger and woke up this morning (1.5 hours later because my phone apparently shutoff). Now it will not show as if it is charging (typically on a wireless charger (have even tried a friends wireless charger to see if that was the problem, to no avail). I have tried all the steps in safe start, etc, but the screen is still black. What should I do? — Paul

Solution: Hi Paul. If this problem occurred while trying to charge your phone wirelessly, consider using a cable charger instead. We can’t say for sure what happened since we don’t know the full history of your device but there’s a chance that wireless charging in your device may not be working as expected. Make sure that you let your phone charge by USB cable first for at least an hour. Sometimes, it can take some time to re-energize a fully drained battery. Once you’ve charged the phone for at least an hour, try to restart the phone to the following modes:

Boot in Recovery mode:

  1. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  2. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  3. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  4. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  2. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  3. Wait until the Download screen appears.
  4. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  5. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Press and hold the Power button.
  2. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  3. Continue holding the button until the phone finishes rebooting.
  4. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  5. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Keep in mind that these are the only steps that you can try in this case. If your phone remains dead or unresponsive, you must have it repaired or replaced.

Problem 3: Water damaged Galaxy S6 won’t charge

My Samsung Galaxy S6 was dropped in a sink but only the bottom half got wet. I went to see if it would charge still but it doesn’t. If I put the charger in the right place it will sometimes charge for a bit but then when I unplug it, it won’t charge again. Should I try to fix it or just sell it? — Owen Langer

Solution: Hi Owen. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so it’s safe to say that there may be some hardware damage in it now. To know the extent of the damage, you must let a trained professional check it. Only then will you be able to determine if you can still save the phone or not.

Problem 4: Galaxy S6 edge won’t charge

Hi. My Samsung Galaxy S6 Edge has stopped charging. This has happened once before so I took it to the shop I bought it from (Carphone Warehouse) and they gave me an adaptive fast charger, which solved the problem. However, this has now happened again, so I asked the Carphone Warehouse again and they gave me another USB lead to charge it. Unfortunately this time it did not charge up and I am left with a phone at 0% charge, unable to do anything myself. I fear it may be a problem that I created by not updating the phone’s software in time, but now I cannot do this as the phone has to be at least 20% charge to update itself. Can you help? Thanks. —  Ciaran Boyek

Solution: Hi Ciaran. Not installing an update won’t prevent charging so we are positive that your issue is not that. This is either caused by a software glitch or a bad hardware.

If you can manage to power on the phone, we suggest that you try a factory reset b following the steps below:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

If your phone won’t turn on at all, use another known working charger and try to wiggle the cable near the charging port. There’s a chance that the issue is charging port related and if you’re lucky, you may be able to charge the phone for at least one more time. If that won’t work though, bring the phone back to the store and have it repaired or replaced.
