Problem 1: Galaxy S6 losing battery power faster after installing an update

I was suspicious of the battery drain (I thought it might just be me), so I charged phone to 100% at 10pm at night. Made sure all apps were updated, closed all open apps, wi-fi on, all notifications turned to silent, then unplugged the charger. By 8am the next day the battery was down to 16%. During the day when I’m actually using my phone, the battery now drains even faster. Figured out this started happening right after the recent update (that also made the text too small to read without my glasses on). Any help you can suggest? — Goodjujucami

Solution: Hi Goodjujucami. Battery drain issue is almost always caused by poor usage habits more than anything else but if you’re 100% that it suddenly occurred after installing an update (this is often a common scapegoat), then it can only one of the following:

  • an app/s (pre-installed or third party) may have suddenly become erratic
  • power management of the device is poorly implemented or not working
  • there’s an unknown operating system glitch behind the trouble

Refresh the cache partition

Because your battery drain issue occurred right after an update, you can eliminate other possible causes and focus on the three items listed above. It is therefore important that you first try to wipe the phone’s cache partition to ensure that the system cache is good. Below are the steps on how to do that:

  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.
  9. Observe the phone for 24 hours to see if there’s any difference.

Check what apps or services are on top of battery consumption list

You don’t need to install another app to do this simple step. Simply head to Settings>Device maintenance>Battery>Battery Usage. In an Android environment, the main power consumers should be system services and apps like Screen, Android System Cell Standby, Device idle, etc. If there seems to be a lot of pre-installed and/or third party apps in the top part of the list, make sure that you deal with them by either putting them to sleep during most times, or by uninstalling them.

Install app updates and remove potentially problematic ones

If there’s no change after a cache partition reset, your next move is to deal with a possible app problem. Bear in mind that not every app is built with the same expertise and resources. Inexperienced and resources-strapped developers often end  up with substandard products, which in turn can lead to problems.

If you’ve already installed all updates for all apps but the issue remains, make sure to restart the phone to safe mode to see if any of the third party apps is behind the trouble. While in safe mode, all third party apps (those that you install after you first setup the phone and not built by Samsung and Google) will be blocked, allowing only pre-installed apps. If the battery will not lose power as fast when the device is in normal mode, it’s very likely that one or a few of your third party apps are to blame.

Now, safe mode by itself is not a solution so if you think that there’s a significant difference in power consumption between normal mode and safe mode, you must invest some time and effort in identifying the culprit/s. You can do that by uninstalling apps one by one, then observing how battery consumption works each day. This will take some time to accomplish but it’s the only effective way if you suspect that an app is to blame.

To restart your phone to safe mode, here’s the steps:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Do a factory reset

One of the effective solutions for issues that surface after installing an update is factory reset. If all our suggestions above won’t work, be sure to wipe the phone with factory reset.

  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 Volume 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.
  9. Observe the phone for 24 hours without installing any app.

Contact your carrier and ask for support

Some post-update issues can never be fixed by an end user simply because they’re caused by poor or inefficient coding. This means that the operating system version itself is problematic because it was not coded properly, or there’s an unknown bug during its release. If the issue remains after a factory reset, contact your carrier for assistance (we are assuming of course that you updated your phone by downloading the files by air, also known as OTA update).

By the way, if you’re wondering how to change the font, font style, and font size on your device, simply head to Settings>Display and around with the options in that section.

Problem 2: Screen of water damaged Galaxy S6+ stays black

Hi. I have a 1-year old Samsung Galaxy S6 Plus. Yesterday, I went running with my phone, played music, it worked great. I had noticed earlier in the week that the color of my screen would change slightly. Not enough to make me concerned. After my run, I took a shower, had the phone in the bathroom at the same time, and afterwards, I had a vertical purple stripe on my phone that wouldn’t go away, even after restarting it several times. Then it suddenly turned black. It still vibrates, some voice on it would randomly speak, and none of the combinations of pushing the buttons down would work (e.g. Volume Down + Power Button for 10-15 seconds).

Today, I hooked it up with a USB to my computer and did the Volume Down+ Power, and got the purple stripe to flash, but still couldn’t get my screen to show up.

I took it to the cell phone repair place. He just cleaned the screen, told me that it was slightly water damaged, and that it would cost $300 to get a new screen, since my probably warranty wouldn’t cover a water-damaged phone and it’s not insured. The only thing I can think of, since I didn’t drop it or anything, is that the mist from my shower must have gotten inside and damaged my phone. Is there anything else I can do or am I screwed? — Kelsie

Solution: Hi Kelsie. Water and electronics don’t mix. Even a tiny amount of moisture can damage a device not designed to resist water so, yes, the phone’s screen may be damaged at this time. There’s no software tricks that you can do to fix that so you have no other choice but to send it in for repair or screen replacement.

Problem 3: Galaxy S6 cannot create back up to a computer, DCIM folder is missing after an update

Since the update, I cannot download photos and videos off my phone to a computer. The DCIM (?) file is no longer visible. I get the massage to allow the phone to be used a s storage device and click on the message, but nothing changes. I can’t use the pro feature in the camera either – the app crashes. The camera was the primary reason I loved the phone. I was considering updating to S7 or S8 to improve the battery, but now I’m considering other non-iPhone because this last update has ruined so many things I enjoyed about Samsung phones. For now, I just want my photos with having to upload to cloud or send via email. — Mitsuko

Solution: Hi Mitsuko. Try to install Smart Switch in your computer and use it to back your files up. If creating a backup via Smart Switch won’t work either, upload as many valuable files to a cloud service as you can before doing a factory reset on your phone.

Problem 4: Wet Galaxy S6 edge won’t charge and turn back on

Hi team! My S6 edge got wet the other day and I tried everything to dry it out. After 3 days i plugged in the charger and it charged and even turned on to the point where i had to put in my pin but then it just crashed and since then, it doesn’t do anything. Doesn’t charge or respond to any input. I checked the water indicator and it is red. My question now is, how do I find the broken part to replace! Cheers. — Max

Solution: Hi Max. First of all, exposing an electronic device to water almost always lead to permanent damage. At this time, there’s very little chance that repair will save your phone.

Secondly, knowing what part is not working can be tricky and requires both expertise and the right tools. A trained technician also has to run a number of tests to determine where the possible point of failure may lie (if that’s possible at this point at all). These tests depend on how a technician approaches the problem, which also largely depends on the physical condition of the motherboard. If you don’t have a solid electronics background and training with Samsung devices, we suggest that you let a professional do the checking for you.

Problem 5: Galaxy S6 won’t read SD card

I own a Galaxy S6. I bought a San Disk 32GB Micro SD Card. This is my first time putting an SD Card to card to my phone since the day of this Samsung Galaxy S6 came out in the market.

So I turned it off then put it in its slot but when I turned it on, the device can’t read it. When I go to settings to see the storage, in the Mount SD Card it says “Insert SD card”, so it means the phone doesn’t recognize my SD card. I turned it off, then on again, restart it, and even factory reset my phone, none. Nothing happened. Please help me. I don’t know what to do. Thank you in advance. I really need your help. — MJ

Solution: Hi MJ. Knowing what’s causing your problem is actually easy. Simply insert the SD card to another known, working phone! If the second phone won’t recognize the SD card either, then it’s an SD card problem. Replace it.

Otherwise, it can only be your S6. since you’ve already tried to factory reset it, the cause of the problem must be hardware in nature. It can be a bad SD card slot so you’ll want to either have the phone repaired or replaced.

Problem 6: Galaxy S6 apps keep crashing

Hi droid guy. Please help me out with the following issue:

  • My S6 Android apps keep crashing one after the other. Model # SM-G920T – Usually starts with weather daemon; then Touchwiz home, media storage and so on
  • Got the phone used. Had been working fine for a month or so.
  • Tried factory data reset multiple times. Phone works fine for a while. But problem reoccurs approx 24 hours after factory data reset.
  • Tried wiping cache partition. Doesn’t work.
  • Tried malware protection & security apps. Didn’t help.
  • Do not have any games or other non-basic apps downloaded.
  • Found out that the OS is custom. Cannot be updated. Currently running on 5.1.1. — Bilalazam40

Solution: Hi Bilalazam40. If your device works fine initially after a factory reset, the cause can only be one of two things:

  • you’re installing a bad app after a factory reset, or
  • the firmware itself is problematic

To check if it’s an app issue, do another round of factory reset and observe how your device works for a longer period without any third party apps installed at all. Let it run for at least 48 hours and see how it works. If everything works normally, install apps individually and observe phone performance again for a day. Do the same cycle for each of your app until you identify the culprit.

If the problem returns right after a factory reset (and even when there are no apps installed yet), replace the custom ROM with a stock firmware.

Problem 7: Dual SIM Galaxy S6 can’t make calls or use mobile data

Hello. I have a Samsung S6 dual-SIM phone, bought in Russia 2 years ago. As of now, I leave in Switzerland and use the phone with 2 SIM cards – from Swiss provider and from Russian one. Several months ago – not sure if with Android 7.0 update or before – the device has started to lose cell connectivity – data is not coming in and I can’t make or get a call from / on any of the 2 numbers I’m using. What is interesting – the phone shows it’s in a network, so I do not know if i’m offline up until I try to call somebody or to use any app outside wifi zone.

Shutting-off LTE, changing the places of the cards, running the phone in a safe mode, wiping out cache didn’t help. S6 dual-sim models were not offered on Swiss market, so services (Samsung and other) refuse to deal with it. Samsung call center’s guys in Switzerland can’t help since the phone was bought abroad, and the guys in Russia know nothing about Swiss network. I haven’t tried to restore the settings to factory ones – do you think this may help? Are there any other actions which may bring the phone back to work? Thank you in advance. — Mikhail

Solution: Hi Mikhail. There’s really nothing much that you can do at this point except to factory reset your device so yes, you want to try that. If the problem won’t go away after that, the problem must be hardware related.

Problem 8: Galaxy S7 stuck in Samsung logo screen, won’t boot past Samsung screen

I don’t remember what version of Android it has and I can’t get it to boot. I see articles such as yours that mention an Android boot animation but I am not sure what that is. When I try to power up my phone it says “Samsung Galaxy S6” but then it says just “Samsung”. After showing just “Samsung” it plays a jingle and then it does not go past there. The two lights at the bottom flash and I feel a slight vibration. The splash continues and the lights occasionally flash and occasionally I feel the slight vibration but nothing else happens. I am not sure what the lights are called but they are the lights/buttons for list of applications and for returning from something. The phone has been acting up. What I did just prior to this problem is that I powered the phone down then removed the SD card, added stuff to the SD card then put it back in. Then I had the problem. I removed the SD card and still have the problem. Since there is a possibility that the SIM card was inserted improperly I removed it temporarily but that made no difference. — Sam

Solution: Hi Sam. Try to boot your phone to any of the three alternate modes to see if you do follow up troubleshooting. We list the corresponding follow up procedures that you can do if you can manage to start the phone to any of them (though you still need to some research for flashing). If the phone remains stuck in its current state and won’t respond to any of the hardware button combinations, it’s time that you send it in.

Below are the steps on how to boot to alternate 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.

Problem 9: Galaxy S6 stuck in boot loop after unrooting

Hey DroidGuy. I need your help. i had rooted my Galaxy S6 edge because i had a problem with S Health and i forced to edit build.prop to fix it. i make it and later i thought that i should unroot my device. i opened supersu and i pressed full unroot and after that bootloop happend. Now my phone only boot up the screen “samsung galaxy s6 edge” then the the screen gets black and again again the same happens. i tried hard reseting my device by twrp which i had downloaded before so i could root but it didnt help me!!! What i should do?? plzzzz i need ur help!!!  — Timosmagkaki

Solution: Hi Timosmagkaki. Many users usually fix boot loop issues by flashing the bootloader. If you haven’t tried that, make sure that you do. If flashing the bootloader won’t fix the problem, proceed with firmware flashing.

Below are the sample steps on how to boot a bootloader. Exact steps may be different for your phone model so make sure to do some research on how to do it properly.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 10: Galaxy S6 won’t recognize apps stored in SD card

I have an unlocked Verizon phone running on Straight Talk. it’s a Samsung Galaxy S6. I could not get YouTube on my data to run and I did not have Wi-Fi. So I factory reset the phone trying to fix the problem. Before I did that, I took the apps I wanted to save and put them on the SD card. I took the SD card out and then factory reset the phone and then put the SD card back. I’m unable to find the apps I stored on the SD card. Can you help? It’s a kernel version 60.1. The email I put on here is not correct it would not take my correct email which is d*** the other email really does not exist anymore. — Dawn

Solution: Hi Dawn. Moving apps to the SD card, then doing a factory reset on the phone might have deleted critical system files used by Android to recognize the apps again. If the apps stored in the SD card were downloaded from Google Play Store, simply redownload them.
