Problem #1: Galaxy S6 stuck in bootloop after it crashed playing Pokemon Go

Hi, I read your page at: http://thedroidguy.com/2015/10/what-to-do-if-your-galaxy-s6-is-stuck-in-samsung-logo-screen-other-boot-issues-1050280. My S6 recently crashed while playing Pokemon Go and is now stuck in a bootloop where the “Samsung Galaxy S6, Powered by Andriod” screen continually refreshes and flashes. I have tried all of the key combinations listed on your page to no effect. When I try to hold the Home, Power and Volume Up button, I never get the vibration and cannot proceed with the process. There is no change in the pattern on the phone or any indication that the key combinations have had an effect at all. My phone model is: SM-G920F and it is a recent purchase. I am not aware of what updates have arrived on the phone or when they arrived and cannot power up the phone at all presently. Android version unknown. Thank you in advance for your response. — Steve

Solution: Hi Steve. There’s only so much that you can do in fixing this problem. If the phone fails to boot in other modes (by doing different hardware button combinations), the only resolution you can hope for is to either get the phone repaired or replaced. Contact Samsung or your carrier to do any of them.

For reference, below are the specific steps on how to boot in different modes:

Boot in Recovery mode

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S6 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S6 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • 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.
  • Use Google to look for a guide on how to do it.

 

Boot in safe mode

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S6’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • 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 #2: A comment on Galaxy S6 RAM

I have seen many people/posts/blogs make the comment “Unused RAM is wasted RAM.” This is blatantly false. If your RAM is near 100% utilization all the time, your entire experience is diminished because of the OS overhead needed to manage the RAM. If you want to open an app that needs 100MB of RAM, and more than 100MB is free, it opens quickly and loads into RAM immediately. You can then switch back to your previous app very quickly because it also is still in RAM. If you have less than 100MB of RAM available, you have to wait for it to become available, slowing down the initial load of the app. Then when you want to switch back to one of your previously used apps, it takes much longer as well because it got unloaded to make room for the new app. Since about 75% of the RAM usage on the GS6 is by the OS and Samsung bloat apps, there is VERY LITTLE space available and the phone is constantly trying to manage this space (and does a very poor job, in my opinion). For example, Samsung boasts that the camera app can load in under 1 second even when the phone is off, through the use of double clicking the home button. WRONG! This NEVER happens during normal use because the RAM is ALWAYS full and loading the camera app in the real world takes minimum 5 seconds, and I have seen it take as long as 20 seconds to actually be useful. More RAM is almost always better, and more FREE RAM is also almost always better. There is no benefit to utilizing all of your RAM all the time unless you have so much RAM that you can load every app and keep it in RAM all the time. I understand that there needs to be a balance, but with large OS files, lots of bloat, and very large apps that are common today, much more RAM is needed and (just as importantly) more FREE RAM is needed. — Ryan

Solution: Hi Ryan. We don’t want to argue but Android operating system manages RAM quite efficiently. While it’s true that a perceptible “lag” may be present

if there’s not enough RAM remaining when trying to open a large app, said lag is often negligible for most Android users as it only takes a few seconds at most. Delay in opening an app can become more pronounced though as an Android device is used time and time again. Keep in mind that RAM management is only one of the aspects in a complex process. The state of the system cache, condition hardware components involved (like the processor), as well as interactions of other codes due to other apps can also contribute to the overall speed in loading a particular app. A freshly unboxed Android device is significantly faster than when the same device has already been operating for several months. That said, you will expectedly notice a difference in terms of performance as your Galaxy S6 matures. It doesn’t mean though that RAM management of Android OS deteriorates or becomes ineffective over time. It only means that other factors now contribute negatively to how the system pulls up an app.

Now, we don’t work for Samsung so if you think that they should listen to your idea about how RAM in a smartphone should work, we strongly suggest that you contact them. We can publish what you think here but we say, you’re barking at the wrong tree.

Problem #3: Galaxy S6 Edge+ keeps getting the charging sound after installing Android update

Hi. I’m having trouble with my charging my Samsung Galaxy S6 Edge+. I still have the same charging box that came with the phone itself. BUT I’m using a different charger cord with the same voltage as the original charging cord. When I go to charge my device, the port, starts to act like I am plugging it in and out when the charger is clearly fully in the device. And when I happen to get it to charge, when it gets off the charger the phone still thinks the charger is in the device and will make the hap tickets noise as if I was charging my device.

I have tried to purchase a new charger and even a new charger box,with the fast charging capabilities. There is NO damage to the charging port nor any debris in the charging port. This started to happen the day after the new update 6.0.1 kernel version 3.10.61. Today is currently September 24 2016. I’d really appreciate if you could help me troubleshoot this problem. Thanks. — Jordan

Solution: Hi Jordan. If the issue happens to coincide after you installed an Android update, the first thing that you want to do is wipe the cache partition. This will help ensure that the device uses a clean and updated system cache. Here’s how to do it:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

After wiping the cache partition, charge the phone again to see if it helps. If the issue stays, the next step is to boot the device in safe mode. This will help you determine if one of the third party apps is the culprit. If the issue won’t occur while safe mode is enabled, you have an incompatible or badly coded app. To boot in safe mode, follow these steps:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • 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.

If the problem will still be there even when safe mode in on, don’t hesitate to perform a factory reset. This is the last software solution that you can try before concluding that you have a bad hardware. If the issue remains after a factory reset and no apps installed, you can bet hardware is to blame. Contact Samsung or your carrier for repair or replacement.

Problem #4: T-Mobile Galaxy S6 Edge won’t connect to Wi-Fi

I recently got my Samsung Galaxy S6 Edge from my uncle. He said it was from T-Mobile and he factory reset it and unblocked it. He told me that it had some issues with it but I don’t remember what and someone “fixed it”. Since the day I got it, it’s been turning off and on on its own and it won’t let me connect to the wi-fi. I pull down the notification settings and press the wi-fi circle to turn it on but the color is a dull blue and not the dark blue it usually is when it’s turning on. When I go to the wi-fi settings, the switch is a dull grey and it won’t let me switch it on or off. If the switch is a light grey and says I can turn it on, and I do, it just turns a dull grey again, it says its turning on but never shows any wi-fi connections. What I found that fixed it was me turning off the phone but if have to do that about 5 to 8 times. And now that doesn’t work anymore. I can’t factory reset it because I needs to be connected to the Internet for that. What can I do? — Reyna2112

Solution: Hi Reyna2112. Well, to be frank, there’s not much else that you can do in this case. That factory reset did not fix the problems you mention here is a clear indicator that either there’s a hardware malfunction on it, or the current firmware is restricted. Your only option now is to see if manually flashing the device will make a difference. Use Google to find a good guide on how to install a firmware yourself. Just be sure to use the correct one. Also, keep in mind that manually flashing a third party or custom firmware may lead to more problems so do it at your own risk. Given the unworkable situation you currently have though, we think you should go for it.

Problem #5: Galaxy S6 Edge won’t turn on

Hello there. My Galaxy S6 Edge will not turn on at all. I was talking on it one day & it just shutdown on me. I thought maybe the battery died so i plugged it in to charge & it didn’t seem like it was charging. The battery picture with the lightning bolt showed up but didn’t show any percentage like usual. I left charging for 2 hours but nothing just the blue light on the top stayed on but i couldn’t get the phone to turn on. I tried holding down the volume down home & power buttons & then tried to restart the phone but all that came up was the Samsung Android logo flashing. I have all my pictures on this phone & don’t want to wipe it out so if you can help me out that would be awesome. Thanks. — Brad

Solution: Hi Brad. We’re afraid you’re going to lose your unsaved files in this case. As we mentioned earlier, a user has very limited options when it comes to an issue like this. If you can’t turn on the phone via the three hardware button combinations we provide above, you can bet the hardware is toast. Because there’s no way to access files of an unbootable Galaxy S6, those photos are definitely lost forever. Refer to the steps above on how to boot your phone in different modes.

Problem #6: How to access a locked out Sprint Galaxy S6 Edge+

I have a Sprint Galaxy S6 Edge+ (G928p). My phone suddenly rebooted and upon startup it told me that fingerprint could not be used and I had to enter a password. My regular password did not work. I have since used almost every password I have ever used on every known device. I have tried to use the Android Device Manager to reset my password, but it only tells me that my device already has a screen password and will not change it. I have tried Samsung’s utility and it says it cannot find my device. I have contacted Samsung and they say Sprint does not allow their device to work with the Samsung tool. I am trying to find a way, any way to get into the phone without losing all of my precious photos. Are there any real options to obtain my photos? — Monica

Solution: Hi Monica. The only way to use a locked out Galaxy S6 Edge is by doing a factory reset, which means you’ll lose all your files. Samsung is of no help in this case either as their only solution is factory reset as well.

To prevent losing important files in the future, always make it a habit to copy them to a second device or save them to a cloud service.
