Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S6 screen flickers and freezes

My phone was working fine then suddenly its screen started to flicker in the morning a bit and by nightfall it was unusable. Screen flickers and hangs and when you turn the screen off and then on again brightness levels are lower than the settings. No auto brightness is on. When i continuously turn on and off the screen it starts working once the screen brightness comes to normal by itself. If i continue using one app for a longer period of time it starts on work smoothly but at one time i can use one app only now. Two apps and the screen becomes crazy. I did a hard reset. No change. Even reinstalled the software still the same. I am thinking about downgrading the software. Help me !!! — Ayesha

Solution: Hi Ayesha. Doing any further software troubleshooting won’t help. If by hard reset you mean factory reset, then downgrading the software version won’t make any difference at all. Factory reset should take care of any issue caused by a a software glitch. Since nothing changed after doing it before, we suggest that you hold off on doing any other software solution. A flickering screen issue is almost always caused by bad hardware so instead of wasting your time in flashing the firmware, just have the phone’s hardware checked by a professional.

Problem 2: Galaxy S6 touchscreen stopped working after it fell in water

Hi. I read your response to the person whose S6 edge fell in water and now the touch screen won’t work. You had suggested a hard reset in which you turn off the phone and then press all 3 buttons simultaneously. The problem with that is that it won’t turn off because the touch screen doesn’t work. If I push all 3 buttons while it is on, it will restart. When I did that, nothing changed–touchscreen still doesn’t work. What do you suggest will be the next step? I’m not sure which version it is. — Gduarte01

Solution: Hi Gduarte01. Exposing a Galaxy S6 to water is like a death sentence. It’s very rare to see a wet S6 survive without a scratch so if you haven’t done the basics like turn off the phone, open up the phone and dismantle parts, remove the battery, and dry the battery and the dismantled parts in a bag of rice for several days, we’re positive that that the reason why your phone’s touchscreen issue is due to a damaged screen assembly. If you’re lucky and water damage is isolated to the screen assembly only, the least that a technician may do is to replace it. That said, your next step is to have the phone checked by a technician so hardware damage can be assessed.

Keep in mind that moisture can stay inside the phone and do damage in the long run (that’s why water-damaged phone must be thoroughly dried). Repair or parts replacement may give your device a short life but eventually, it will still fail. Water, especially salt water, can lead to corrosion and corrosion can take some time to develop. If your phone will suddenly show problems weeks after repair, you’ll know your phone’s end is near.

Problem 3: Galaxy S6 won’t turn back on after it got water damage

Hi there. My daughter dropped my phone into the toilet. It was there for around 30 – 45 seconds. It was a clean toilet so only water there. I currently have it in rice, SIM card has been removed and the SIM tray also. Inside, i cannot see any white/red/pink. just silver/black. The phone was on as it went into the water, it came out not working, no lights/sounds etc. Any idea on what i can do? Thanks in advance. — Taragreeneyes

Solution: Hi Taragreeneyes. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so it’s safe to assume there’s an on-going hardware issue preventing it from turning back on. Putting in inside a bag of rice won’t do much good at this point. You’re supposed to do that only after removing the battery from the system. Leaving the power source connected to a wet motherboard can short components, which can then lead to permanent hardware malfunction or failure. If you can’t open the phone yourself and do this critical “first aid,” we strongly suggest that you send the phone in or let a technician check it right away. It won’t guarantee that your phone will work normally again but at least you’ll get an objective assessment whether or not the device can be saved or not.

Problem 4: Galaxy S6 shuts down randomly, wifi won’t remain connected, weather app not updating after an update

I have a few issues with my phone and the cause could be related. They all started a couple months ago after a software update it seems.

  1. phone turns completely off randomly. sometimes it will stay on most of the day and most of the time it will shut off a number of times in just a few minutes.
  2. wifi….will not stay ON nor will it connect to a hot spot even at home unless I power down the phone and re-start.
  3. the weather app that came with the phone will not update itself. Its preset to update every hour but will not and it takes some fiddling with the screen to get it to update.

You asked for a version of phone I have but I am not sure what it is. I just entered what looked good to finish form….sorry thanks for any help you may offer. — Jim

Solution: Hi Jim. The first possible solution that you want to try is to wipe the cache partition. This will ensure that the system cache is not corrupted. System cache corruption sometimes happen after an update, leading to all sorts of trouble. Refreshing it though usually works. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. 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.

If the problem persists after refreshing the system cache, you can then try factory reset. This will wipe everything on your phone and bring all software to its defaults. If there’s a glitch causing the problems above, factory reset should take care of them. Here’s how to do that:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6 Edge.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. 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.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem 5: Galaxy S6 screen won’t work after it got wet

So I dropped my phone in my pedicure water at the nail salon. I immediately picked it up and dried it off. It didn’t get completely submerged. I think it was the top half that went in, not sure. Anyway, the phone will charge and turn on, but the screen won’t turn on. What I want to know is, is there anyway of getting my pics, contacts, etc off of it without the screen turning on? The buttons at the bottom light up white, it make the t-mobile chime when it powers on. the Light comes on when it’s charging. I just wanna know if there is any chance of getting my stuff off of it before I throw it out. Thanks! — Chris

Solution: Hi Chris. You’ll need a working screen in order to give permission for another device like a computer access to the internal storage device. Plugging it directly to a PC via USB, even if the computer can still detect the phone, won’t necessarily give it permission to browse the contents of your phone. That’s not how Android works. If you think the contents are worth a few hundred dollars, try having the screen replaced to see if it will work again.

Problem 6: Galaxy S6 in-vehicle Bluetooth speaker not working properly after Nougat update

Hi! So Nougat >:( (said in Jerry Seinfeld’s “Newman” voice). Ever since this update, my Bluetooth connects, but all callers hear their voice echoing back at themselves when I’m connected so it’s basically useless. I have to switch everyone off bluetooth and on to speaker phone so they don’t hear the echo. I’ve unpaired and removed the phone from the bluetooth in my car. I’ve done every reboot imaginable. I’ve reset the phone. Still, the problem continues. It’s SO frustrating! I can’t hear anyone through the speaker while I’m driving, and I can’t put them on bluetooth because they can’t hear themselves think when their voices echo back at themselves while they’re talking. Help!! — Bari

Solution: Hi Bari. An issue like this is common after an update. The surprising thing is, yes, it was the update on your phone that caused it, but it’s really not your phone’s, or Samsung’s, or Google’s fault at all. Smartphones receives more software updates than in-vehicle Bluetooth devices, which means that their Bluetooth system are more up-to-date. Now, when was the last time you ever updated your in-vehicle Bluetooth system? That’s where the problem usually lies. In almost all cases like yours, incompatibility issue occurs simply because of an older in-vehicle Bluetooth. At times, the profiles used by a Bluetooth device becomes incompatible with another device due to updates as well. If you’ve already tried doing a factory reset on your phone (to make sure that this is not an Android software issue), we suggest that you contact the maker of your car or the bluetooth device in it to see if there’s something that they can do.

Problem 7: Galaxy S6 stays black after battery replacement

I have a Galaxy S6. The screen went black and I had just paid to have the battery replaced. Well, 2 days after, the screen went black. I keep trying to hard reset and it will flash blue at the top bit isn’t showing anything on the screen. I am not sure if it’s the battery or if it’s the screen? I don’t know how the screen would be damaged because I haven’t dropped it. Maybe the screen connection is loose? Could you clarify if it’s likely the screen or the battery? — Cayla

Solution: Hi Cayla. It’s clearly not a battery issue. If it’s a battery failure, there wouldn’t be any LED light showing at all. To get to the bottom of the issue, you want to let a professional take a look at the hardware again.

Problem 8: Galaxy S6 edge plus keeps crashing, stuck in boot loop

Hi, I have a Samsung edge S6 plus and it keeps crashing, a blue light comes on and it gets stuck in a loop of the first Samsung black screen with model logo and then black Samsung loading page. and then it crashes again and it’s in this loop continually. eventually I don’t know how but it starts working again. This time however it wouldn’t restart. so I followed your page advice of holding down volume up, home key and power button but I can’t clear cache as my phone now has a blue screen with a robot with a refresh button in its tummy and white words at the bottom which say installing system update. I’ve plugged it back into the charger but I don’t know what to do now. Thank you and I guessed the android version, I’m not sure. Thanks again. — Amy

Solution: Hi Amy. If you’re trying to boot to Recovery mode and you’re doing it right, you should be in a different page than the one you’re seeing right now. We think you may be at Odin or Download mode, which is accessed with a slightly different button combination. Please refer to the steps below on how to boot your phone to each of these modes:

Boot in Recovery mode:

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

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. 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.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. 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.

Remember, if your phone continues to reboot on its own, or won’t even restart normally, there must be a hardware issue causing it. You must have it repaired or replaced.

Problem 9: Galaxy S6 edge won’t charge via USB cable after an update

Hi. I have a Samsung S6 edge and over the last week or so I’ve had major charging issues. I updated the software after a notification. This is, I think, has been the start of my problems. I can charge the battery wirelessly, however 90% of the time when I charge via the cable it doesn’t recognize it, flashes up usb connected, gives the power sharing message or constantly flashes on or off charge. I’m guessing a software issue but I have done all the necessary shutdowns resets etc including factory reset. Does this mean my charger port/battery needs replacing? — Chris

Solution: Hi Chris. If your phone charges wirelessly without a problem, the problem is most likely found in the charging port. It may no longer be working properly and the system mistakenly detects the charger as another device. If a factory reset did not change anything, you should seriously consider sending the phone to be repaired or replaced.

Problem 10: Accidentally dropped Galaxy S6 Duos won’t read second SIM card, SIM card slot not working

I have a Samsung Galaxy S6 Duos that has work well for over 9 months. However, I recently dropped it (it has a protective cover) and the second SIM has not worked since. The SIM is OK since I can switch locations and it works fine in slot 1. I am presuming that either the contacts for sim slot 2, or the antenna (if they are separate), has been jogged or damaged somehow. In your opinion is this worth trying to get fixed (and how many shops have any experience of dual sim phones in the US) or should I simply get a new phone? — Paul

Solution: Hi Paul. The best person that can give you a more authoritative answer is the technician who has physical access to your phone. The hardware must be thoroughly tested first in order to know where the problem lies.

If you badly need the second SIM slot for your lifestyle though, we recommend that you simply get a phone replacement.  Unless an attending technician is 100% sure that he or she can fix the problem, there’s really no point in spending your money for an unguaranteed repair.
