I recently got a Galaxy S6 from a friend who owns a phone store so i have no real clue as to how old it could be. Ever since i got the phone and set it up i have been having problems with the phone lagging, for lack of better word, and most notably when I’m watching videos. but it happens a lot no matter what i do. i can be scrolling the screen, reading something or what. it doesn’t matter, it always lags. It’s to the point where it’s almost unbearable. Especially when i’m trying to watch YouTube or trying to watch TV because the video will freeze but the audio will keep going fine and wont lag at all, just the screen.
I’ve done a little bit of research and found out that a lot of people with the S6 and S6 edge have been having problems with the new android 6.0.1 update and have been having a lot of lagging and other issues. I was just wondering if that could be the issue or if it could just be the phone. i tried resetting the phone and that did absolutely nothing. Should i return the phone to him and see if i can get another S6 or maybe a different phone? or should i try rolling back the operating system on the phone and wait for a new update. — Kyle
Solution: Hi Kyle. If basic software troubleshooting did not work and you still have the option to get a replacement unit, we say you go for it. The software troubleshooting we have in mind for you includes:
- wiping the cache partition
- booting in safe mode
- Installing updates for the operating system and apps
- uninstalling apps
- factory reset
If you’ve already tried all of them before you contacted us, chances are hardware is to blame. Slow performance or lagging issue can be caused by hardware as much as software. Thus, if nothing changes after a factory reset, the ultimate software solution that an average user can do, you can assume the issue lies in the hardware department.
We advise against downgrading to the previous Android version if there’s a much better choice — phone replacement. Try demanding for a different phone or Galaxy S6 instead.
I wanted to unroot my phone because some apps will not work with a rooted device. so i downloaded the odin and followed every step but it failed. So i tried to turn my phone off to go back to my normal phone and the message popped up that “an error has occurred while updating the device software. Use the Emergency Recovery in the smart switch PC software.” So i installed the Smart Switch but it was not in support of my device and also i dont know the serial number and there is no other way to get since i can’t get into my phone. I’m also not so sure if i used the right stock firmware and if i used the wrong one. I don’t know to get the right one since i can’t get into my phone. I really need help so Please help me fix my Phone. I need it to be fixed!! — Roxanne
Solution: Hi Roxanne. First of all, we always assume that people who root their devices know what they’re doing and are aware of the risks involved in doing it. We say the same for those who root and install custom ROMs and other unofficial software. Both of these groups must be aware that modifying official software can sometimes lead to complications and that they should be able to handle whatever situation that may arise. This is the main reason why we don’t discuss solutions for modified systems in our blog and we always refer questions such as yours to other third party forums. Most of the time, solutions to root- or flashing-related are very specific and requires special knowledge of the developers, thus they may be difficult to come by in mainstream Android forum sites. As much as we would like to help you, we may not be equipped to provide solutions. That’s why you must go back to the source of the software so they can provide you with first hand solutions for their products.
Secondly, we can only discuss rooting (or unrooting) in very general sense here. Telling us that you want to unroot is not very helpful and does not give us any good point where to start. Unrooting, like rooting, can vary and there can be a specific set of steps that you must follow to do it successfully. The said steps also depend on what changes you did to your phone after rooting it. If you did more than root your phone by installing other custom firmware or recovery, the issue may be more complicated than you think. We won’t discuss any particular unrooting method here but you can search for specific answers via Google. Better still, try looking for specific forums or websites that can guide you to the source of the root or custom software.
Finally, keep in mind that unrooting an Android device can be done almost always by flashing/installing a stock firmware via Odin. If you’ve already tried that but the issue remains, that can be an indicator that you may have permanently bricked your device (but then again, we think you already know that). In that case, you may be looking at an expensive paperweight right now. But then again, don’t give up just yet. Try to find visit other forums that specializes in rooting or modifying Android firmware (like XDA-Developers Forum) and see if you can get the solution you need.
Hi, I have a Samsung S6 and it recently got water damaged. I was told that the IC chip was damaged so I bought a new motherboard for the phone. After replacing the mother board the phone is charging for a couple of minutes then going black and showing a red light beside the front camera. It does not respond to anything at this stage apart from when I hold in the power, volume up, and volume down buttons together. When I do this it goes back to the charging screen but won’t react to anything. Thanks. — Eamon
Solution: Hi Eamon. Your situation is one of the reasons why we don’t recommend do-it-yourself hardware replacements. Even Samsung service centers seldom perform motherboard replacement in a damaged unit because it’s a highly unreliable solution. To tell you frankly, we can’t be certain what’s wrong with the device. Even a good technician will have to spend hours checking the hardware before the possibility of an effective repair can be achieved. Telling us that the phone is unresponsive and showing a red light is vague and doesn’t point to anything specific. We imagine the phone doesn’t turn on but as we’ve said, a thorough examination is needed to get to the root of the problem. If you can’t handle the repair yourself, consider letting a professional do it for you.
Hi. My name is Jacob Lawrence. I’ve been experiencing a problem with my Galaxy S6 for a couple months now. It is a “like new” refurbished phone. The problem began with the original fast charger and USB cable. Over time the cable began to work less and less with my phone until my phone wouldn’t even recognize it anymore. So I switched to a different regular USB cable and it seemed to solve the problem until the same thing happened again a month or two later. Now, I have gone through about 5 different cables and am starting to experience problems with the battery jumping percentages during the time it is off the charger. I am hoping you might be able help me in some way or have an answer. Thank you for your time and I hope to hear from you. — Jacob
Solution: Hi Jacob. Try to recalibrate battery reading on your phone first to see if you can make the operating system gauge battery levels. This can be done by doing the following steps:
- Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
- Turn the phone on again and let it turn itself off.
- Charge the phone without turning it back on.
- Wait until the battery says it fully charged to 100%
- Unplug the charger and turn the phone on.
- If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
- Unplug the charger the turn the phone on again.
- Use the phone until you drain the battery down to 0.
- Repeat the cycle once.
Once you’ve recalibrated the battery, observe the phone for a few days. This will give you enough time to notice how the device reads the battery levels.
For your main issue regarding the phone not recognizing the charger after using it for some time, we doubt if there’s anything on your end that can be done. Still, we recommend that you do the basic software troubleshooting like wiping the cache partition, booting in safe mode while charging, and factory reset. If the issue persist after doing all these procedures, you can say that hardware may be to blame. It can be a bad charging port, a faulty battery, or other problematic hardware components.
For reference, below are the steps on how to perform these procedures:
Wipe the cache partition of Galaxy S6
- 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.
Boot the Galaxy S6 to safe mode
- 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.
Factory reset a Galaxy S6
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- 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.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
Hi. I have this issue with the Samsung S6 sm-g920f, I was wondering if you can help me with. Previously, when I plugged it in it would get stuck with the battery icon with lightning bolt. when I plug it in to charge the battery, the back gets really warm but the light never turns on on the upper left corner saying it’s charging.
I tried to do a factory reset using the power, volume up, and home buttons. But it would not do it. I ended up flashing the latest Samsung s6 sm-g920f factory firmware using Odin.
Now when I turn on the phone while plugged in it would get stuck on the Android logo screen and when I charge the phone the back still gets very warm but the upper left light still does not come on.
The phone seems to take a little bit of a charge when I plug it in for 20 minutes but I can’t turn it off, it eventually turns off I’m assuming because the battery drains to nothing.
Do you have any idea what’s wrong with the phone and what I need to do to repair it?
Thanks for your time and assistance. — Eddie
Solution: Hi Eddie. You seemed pretty familiar with flashing so we’re wondering if you did try to modify the official software prior to noticing the “first” issue, which is the screen getting stuck when charging. Abnormal software or operating system behavior tends to happen more frequently when users start tweaking something that they’re not supposed to. If you are fond of modifying or using third party software and rooting, the only solution that may help you right now is by flashing a known working firmware, probably the one that came when you unboxed the phone for the first time. That said, try to flash the Android version that worked properly prior to noticing the problem. Avoid installing the latest iteration of Android as they sometimes come in unrefined versions resulting to bugs and glitches from time to time.
For your question, “Do you have any idea what’s wrong with the phone and what I need to do to repair it?” our answer is no. We have no idea what’s wrong with your phone, especially that it’s running an unofficial software. For all we know, the firmware you installed may be buggy or unstable. We’re not also sure if repair is necessary in this case given the fact that your problem description only appears to mention some software tweaks you did and there’s no mention of anything that may cause hardware components to fail.
Hi. I bought a new Samsung Galaxy S6 Edge+ which I’ve had for about 6 months. I haven’t had any issues with it up until a few days ago. First it started out with me not being able to charge it. My friend had the same issue and suggested I used the wireless charging, which works. We thought maybe the charging port was dirty. Then my phone started to glitch. The screen would turn black and had a small “x” in the corner. It would make a weird noise which I did not have set for a notifications sound or anything like that- I’ve not heard it before. Then the Gear VR screen would pop up. In between each glitch I can charge my phone through the port. However, sometimes that spazzes out too and I can’t charge it regardless.
I put my phone on safe mode to see if that would isolate the problem. But, it still glitched. I have read about the hard reboot and I am thinking about doing so to see if the this problem will be resolved.
Do you have any idea about what this problem could be and how to fix it?
Thank you for your time. — Tyler
Solution: Hi Tyler. The two concerns may be related so the first thing that you want to do is to disable any Gear VR and related apps. Doing so will prevent the annoying popups and may also bring back the normal charging function of your phone. To disable an app, follow these steps:
- Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
- Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
- Once in there, click on an application.
- You’ll now see a list of stuff that gives you information about the app, including Disable, Force Stop, Storage, Data Usage, Permissions, Memory Use, and more. These are all clickable items. Tap on Disable.
- Do the same for other Gear VR-related apps you may find on your phone.
