Problem 1: Galaxy S6 screen stays black, won’t turn on
I have a Samsung Galaxy S6. It doesn’t display and doesn’t finish booting up (it boots up forever). I have been to the official Samsung service in my country and they say they will replace screen AND wipe out data if I fix it within warranty. I do NOT want my data wiped out (there are pictures I care about and other important stuff). I asked for an official diagnosis instead. The result was a defective screen, and nothing else. So, officially, nothing is wrong with the phone except screen, meaning I should be able to connect to PC and call myself. The reality is that it will NOT turn on (infinite booting up… or at least I assume it’s booting up: the blue LED at the top is on. Forever).
I got a second opinion and they said yes the display must be broken. The second opinion was only by phone, but I describe the malfunction in greater detail (including the fact that initially it showed weird lines like old tube TVs; it has long since stopped showing even that, now the screen is completely black. I can only guess what is going on based on LEDs) and they said, yes, it must be the screen, specifically the display driver. So…. all indications suggest…. broken diplay driver+software malfunction of some kind resulting in infinite booting up. And these two problems suddenly occurred simultaneously (initially i thought the phone suddenly died; I was reading something on it on the street, turned my head for a second the next second i looked at my phone and it was dead. I tried turning it on and…. black screen with blue LED). Either this is an incredible COINCIDENCE, or the display caused a software problem. I could replace the screen at a high cost (outside the warranty). The questions are:
- What are the CHANCES that it will work normally again?
- If it is booting up indefinitely now, will replacing the screen make it work again? Or is it a guarantee the software is terminated and my data was lost the moment it went black? Thank you.
PS: I don’t remember the OS. It was probably Kitkat or Lolipop, I’m not sure.
2nd PS: I tried using the Volume down+power to simulate battery disconnect. The WEIRDEST thing happens: When the blue LED is on, my computer (windows xp) doesn’t do anything. When I simulate battery disconnect and thus SHUT THE PHONE DOWN… it says found new hardware: MTP device. Sometimes it says things like gadget serial and samsung USb bla bla, i dont remember exactly. When it does “find” the phone, ALL LEDs are CLOSED. IF I turn it on and the blue LED comes on, the computer reacts as if the phone was disconnected. This doesn’t make any sense. — Serban
Solution: Hi Serban. Frankly, we’re in no better position to diagnose the problem. Your descriptions here are very general in nature and do not provide any specific information that can help us identify the real issue. But since the phone appears to power on as LED light is working, we can also say with certainty that the screen may be malfunctioning. We don’t know how you determine the phone is having a boot issue (doesn’t load normally) when the screen stays black all the time but if you’re certain that that’s the case, you should let a professional check the hardware physically.
And no, screen replacement is not a guarantee that your phone will work again. This is the main reason why you have to let a professional examine the device and do the repair or part replacement for you. There are cases wherein a black screen issue is not the issue itself but rather only one of the symptoms of a deeper problem. For example, if the motherboard is broken and the device’s display chip is damaged, one of the symptoms that a user may experience is an unresponsive or black screen. In this case, replacing the screen won’t fix the problem.
If you’re lucky and the issue is isolated to the screen only, replacing this component should bring the phone’s normal functions back. If the problem involves some other components in the motherboard though, there may be a need to replace the entire motherboard, which means that your data will be good as gone. Again, it’s the call of the attending technician on how to fix the issue after a thorough troubleshooting and diagnostics.
Smartphone hardware troubleshooting is way more difficult and trickier than software troubleshooting so there’s not much online literature available. We suggest that you let a someone who does phone repair for a living do the job for you.
Problem 2: Galaxy S6 edge won’t install update
Hello. I got a Samsung S6 Edge SM-G925F, with the 6.0.1 update. I still have not received the new Nougat update. My friend who has a Samsung S6 has received the new Nougat update. I tried everything, resetting, shutting it down then powering back up.
Also, I currently live in the Middle East, U.A.E and my phone carrier is Etisalat. I would like to know how to get the new Nougat update. Thanks in advance. — Ismail
Solution: Hi Ismail. We are assuming that you’re wondering why you haven’t received any system update notifications at this time yet. Well, there are some things that your device must meet first before it can download an over-the-air update (OTA). Below are the items that must be true in your phone:
It must be in your home network. Before a carrier sends a notification to a device connecting to its network about an Android update, it checks first if said device is compatible or not. If your S6 was built for another network (not Etisalat), it’s current firmware version must not be compatible with the available firmware of Etisalat. This means that Etisalat will never prompt you for an update to avoid causing problems.
Phone must not be rooted or running custom ROM. In most cases, carriers will allow users to download official firmware version even if the device is rooted or running non-official ROMs. However, some may not do that at all to avoid damaging a device’s firmware. There are also other custom ROMs that actively prevents a device from downloading official software so if your phone is not using official software, we suggest that you revert its stock firmware first before attempting to download an update from your carrier. If your phone was never rooted or running non-official ROMs, simply ignore this.
There must be enough available storage space. Make sure that your phone can download the entire update file (APK) by having more than enough storage space.
If all three items are already met but your phone still fails to get an update notification, consider using Samsung Smart Switch. You’ll need a PC to do this though so if you have one ready, simply install the Smart Switch app to it, then connect your phone via USB cable. Then, open the Smart Switch app in your PC and see if there’s a prompt that tells you there’s an available update for your phone.
If Smart Switch will not prompt you of an available update, you have no choice but to manually update your phone. This process is called flashing and it requires some advanced steps. Make sure that you do some research before doing it to avoid committing mistakes. Flashing is inherently risky and can potentially damage your phone’s software for good if not done right. Be sure to look for a good guide online.
Problem 3: Galaxy S6 can’t download files bigger than 16 MB
Greetings. I have a huge problem with my Samsung S6. It shows that my available internal memory is 27 GB, but when I try to download or receive files it says ”insufficient memory.” I even tried to reset and erase everything in my phone but I can’t download something more than 16 MB when it is empty, and I wonder why because free memory is 27 GB. It’s not even 10% of the internal memory that has been used. So how can I solve this problem? Thank you in advance. — Tembejm
Solution: Hi Tembejm. Sometimes, a problem like this can easily be fixed by a simple restart. If you haven’t tried that yet, be sure to turn off the phone and wait for 10 seconds before turning it back on.
If restart won’t fix the problem, try wiping the phone’s cache partition. There may be a bug in the system cache that causes the phone to act erratically. To wipe the cache partition, follow these steps:
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
If wiping the cache partition will not fix the problem, consider wiping the entire phone with factory reset
Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
- From the Home screen, tap the Apps icon.
- Find and tap the Settings icon.
- Under the ‘Personal’ section, find and tap Backup and reset.
- Tap Factory data reset.
- Touch Reset device to proceed with the reset.
- Depending on the security lock you used, enter the PIN or password.
- Tap Continue.
- Touch Delete all to confirm your action.
Problem 4: Galaxy S6 showing pop ups when charging
I recently downloaded the latest update to my Galaxy S6 (7.0 G920AUCU6EQCF) and I haven’t downloaded any apps at all for a while. But since the update last week I am now getting pop up ads when I charge my phone in the morning. They just start playing. I have researched this issue and none of the solutions I found worked. I really don’t want to do a factory reset. Hopefully you can help with this. — Mike
Solution: Hi Mike. We’re afraid you’ll eventually need to do a factory reset for this one but if you want to delay doing that, you can try checking your apps for the moment.
Start by booting to safe mode. Safe mode blocks third party apps and services so if a malware attaches to one of the installed apps, the pop ups should not show while charging in this mode. Here’s how to do that:
- 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 pop ups continue even when you’ve switched to safe mode, your next move would be to empty your phone of all third party apps. This is easily done in one stroke with factory reset but since you don’t want to do that, you’ll have to ensure that there’s absolutely no third party apps left running. This way you can compare the phone’s performance when it has third party apps running and when it’s only pre-installed ones.
Problem 5: Galaxy S6 can’t copy pictures to PC after an update
“Forced” Samsung OS upgrade a couple of days ago. Now, when I connect my phone to my PC to copy pictures, new pictures do not show up in file manager. I can search for the pictures and can find them, but then I can only copy one at a time from the search screen. I have been successfully connecting my S6 to my PC to copy pics for ages! Now, all I can see are the pics prior to the update date! — Jenni
Solution: Hi Jenni. System updates change core operating system files and sometimes, file directories can change by design or due to a bug. We might never know what caused the bug you’re experiencing right now but if you want to eliminate it, you must do some troubleshooting. The first one is cache partition wipe. If that won’t fix it, do a backup of your files by using Samsung Smart Switch. Once you’ve done that, you can then proceed with factory reset.
Problem 6: Galaxy S6 won’t charge, won’t turn on
Hi. Thank you for taking the time to read this. My device is approximately 4 months old. I tried powering it yesterday using a power bank. It worked fine all day then I noticed when I tried to use it again it wouldn’t power up. I have tried several different cables and plugs, including the one that it came with. Now it will not charge or show any signs of charging. Is there any way I can power it in order to reboot the firmware? Any help would be appreciated. Kind regards. — Carla
Solution: Hi Carla. An issue like this can be due to a few factors such as a bad charging port, malfunctioning battery, or some unknown motherboard problem. Unlike older Galaxy S models like the S5, you can’t simply remove the battery and replace it with a new one to test if it’s a battery issue. Obviously, you can’t also know whether the charging port or motherboard are working or not so there’s not much that you can do.
To see if it’s a charging port problem, you can try to use a wireless charger. If the phone charges fine wirelessly, you need to send the phone in so the charging port can be replaced. You need to also send the phone for repair if it’s a battery or motherboard problem.
Problem 7: How to change Galaxy S6 screen sensitivity
Have a Samsung Galaxy S6 phone and I’ve been trying to figure out how to change the sensitivity touch on this phone. I’ve went into settings and the display and it don’t show anything. I’ve also looked up online how to do it and the steps they said wasn’t on my phone. I’ve changed the pointer speed and seems ok but I would like to know if there’s even a way to change the sensitivity. THANKS . — Lori
Solution: Hi Lori. There’s no option under Settings app that you can use to change touchscreen sensitivity. Samsung locked the default sensitivity and all you can do about it is to refresh touchscreen sensitivity firmware. If you’re not having any problems with the touchscreen, we suggest that you refrain from updating whatever sensitivity setting your phone currently uses. However, if you want to give it a try, you can follow these steps:
- Open dialer app (Phone app).
- Dial “*#2663#” (without the quotes).
- Tap on the box that says TSP FW update (General).
- Wait for the system to finish updating the firmware.
We don’t know your reason why you want to change your screen’s sensitivity but if it’s no longer working as expected, you’re better off having the phone repaired or replaced.
Problem 8: Galaxy S6 wifi and cellular connection not working after rooting
i recently purchased a Samsung Galaxy S6 with the intent to root it. After an initial attempt to flash a file to the phone, i have lost wifi and no longer have the ability to check for software updates. The wifi tab is grayed out and the phone no longer detects nearby wifi. The phone boots properly. Subsequent attempts to flash back to stock ROM have been unsuccessful. Even though Odin completes the flashing process without errors, the phone still is missing wifi and the software updates selection within settings. Intermittently when I attempt to make a call “No Network” pops up on the screen. Please help…I do not know what else to do. — Richard
Solution: Hi Richard. As we’ve always preached in almost all our posts, rooting and flashing, when not done properly, can lead to software problems. Before you rooted your device, you should have known that you are potentially changing core Android files and there’s a chance that you may cause irreversible software damage. That’s why almost every rooting and flashing guide comes with a disclaimer that you understand the risks. Only advanced users try rooting and flashing on their phones so if flashing stock firmware won’t work in bringing the normal functions of your device, we think you’ll have to live with it.
Rooting and custom ROMs/firmware are usually developed by brilliant Android users with help from Android community. Try to contact the developer of rooting or flashing software you used to see if they can give you any advice. Rooting or flashing problems usually have their own specific solutions so you have to do some research to find your answers. We don’t even know what software you used so we don’t have the slightest idea which direction you can go to first.
