Problem #1: Galaxy S6 lockscreen swipe pattern not working after Marshmallow update

I need help. Marshmallow updated onto my phone and now the swipe pattern doesn’t work and I’m locked out. I have Sprint, Samsung S6 it is saying wrong pattern 1 hour wait time between. it is the correct pattern prior to going from Lollipop to Marshmallow Android 6.0.1. It gives you option to enter backup PIN which I am entering correct back up pin & not working either.

Lollipop used to let you use Google back up password but Marshmallow doesn’t. I will not factory reset as I know one day (hopefully today) there will be a work around.

I tried find my device through Samsung but it isn’t compatible with Sprint. Tried Google Android Device Manager, to reset password, it says phone is already locked. So no simple way to crack through but I am hoping someone out there can give me the fix. — Joe

Solution: Hi Joe. The primary reason of a lockscreen is to prevent unauthorized parties from snooping on your device or stealing sensitive personal data without your consent. Needless to say, it’s a simple yet effective layer of protection for any smartphone today. We don’t see the logic of a system update like Marshmallow locking up the screen though. There must be a firmware glitch that caused it to lock up the device on its own.

We are not aware of any other ways to unlock a Galaxy S6 other than through a factory reset (and the rest of the options like entering a backup password, unlocking via Android Device Manager or Samsung’s Find My Mobile tool). If you want to continue using your phone as soon as possible, we say you have no other choice but to do a factory reset.

Problem #2: Soft reset good solution for Galaxy S6 power issue

I don’t know how else to contact or suggest anything so I am doing it here, whether you ignore it or not. So, first of all my Samsung Galaxy S6 edge randomly shut off, even though I was just using it. I take good care of it. its only fallen off the sofa a few times but it’s in a protective case. That aside, it wasn’t booting up, wasn’t doing anything no matter what I did. I Googled and this site came up. I looked at all your guides on not turning on, not booting, etc and none of your guides were helpful. For reasons of. If the phone won’t even turn on, how do you expect someone to turn it off and enter safe mode???

So I’m going to give you a helpful tip. I called AT&T and asked them. The lady told me to do as follows: Hold both the POWER button and the VOLUME Down button for 30+ seconds. if that doesn’t work, bring it in. So i sat there and did it and it worked. The lady then told me that it’s a soft reset that happens. So, try saying this little suggestion on your guides before people start tearing apart their phones. And sorry if I sound rude. I don’t mean to be honest. — Tristen

Solution: Hi Tristen. We’ve written a lot of guides for all sorts of Galaxy S6 power issues and the troubleshooting tips and solutions we usually suggest are catered to answer a particular problem description we’re given. These solutions are not meant to address the entire spectrum of power-related issues on a particular device as they are specific to the case at hand. We are positive though that we also suggest doing a soft reset (holding the Power and Volume Down buttons) in some other cases, though not in all. Soft reset is the equivalent of pulling the battery out (for phones with removable batteries) so it’s a worthwhile step to do. You must have stumbled upon a certain guide that did not mention a soft reset because maybe the user has already mentioned doing it in the first place, or if the device keeps rebooting on its own. If you have the time, kindly provide the link of the guide you’ve tried so we can update it and add soft reset to existing solutions.

Problem #3: Galaxy S6 stuck in bootloop and won’t go to recovery menu

Sir, Please help. I believe I have a virus in my Galaxy S6 edge. I am stuck in a boot loop with a single blue light on the front. My phone will reset but go right back in the loop it goes. I cannot do a factory reset. When the little Android guy pops up, the ball he’s holding soon freezes until the battery dies or i reset it back into the boot loop. I can however get to the custom OS screen and it functions correctly. HOWEVER when I plug It up to my computer, the computer does not acknowledge that the device is there, even though my computer makes the “ping” that a new device is connected.

Would Odin be able to pick up my device if the computer doesn’t recognize it?  Any suggestions would really help me out. Kinda in a bind right now,  thanks for the time!

just to recap.

1) Says Galaxy and black screens with solid blue light

2) freezes on the way to Factory default menu

3) Not registering on pc. — Erin

Solution: Hi Erin. We don’t know the full history of your device so there’s nothing much that we can recommend. Telling us the symptoms only doesn’t help much in coming up with solutions. We need to know more information and not just the ones you mention like that the phone may be infected with a virus, or that it’s doing a bootloop.

However, if you customized the software by rooting or installing a custom ROM or recovery, we suggest that you revert everything back to stock to see the difference.

If you did not try any software customization prior to experiencing the problem (though we doubt that you didn’t), manually installing a stock firmware should help. We don’t a specific guide on how to flash a firmware to a Galaxy S6, especially for your specific model so you have to do extra online research for a good guide. Try to use Google to look for a guide on how to flash a stock firmware for your device. Keep in mind that there are many firmware versions for Samsung Galaxy S6 so make sure that you pick the right one. Flashing an incorrect firmware can brick your device so be sure that you follow instructions carefully.

Problem #4: Solutions to a Galaxy S6 lag issue after updating to Marshmallow

So as mentioned, I have a Samsung Galaxy s6 edge on Verizon running marshmallow. This is a top-of-the-line phone from just last year, running the latest version of Android, and I’m pretty sure this thing has an octa-core processor and a ton of RAM, like 2.5-4 GB? And yet, with all this top-of-the-line stuff, it’s still laggy!!!

I mean, it’s not like it takes long to turn on or load apps or anything, but no matter what I do, it’s ALWAYS stuttery and laggy! I honestly wish I was someone who wasn’t bothered by that lol, but every little stutter and jerk on the screen drives me crazy. It’s mainly in doing things like pulling down the notification bar, opening settings from the shortcuts on there and sometimes apps, and scrolling. The scrolling really gets me. Especially in chrome. When I’m trying to read something and it stutters several times with each swipe, I lose a bit of sanity every time. To be fair, I am running a lot of apps at once. But I’m a power user, and closing all my apps or restarting it every time it slows up isn’t really an option, since I’d have to do that every couple hours, and that would really impede on my productivity. Because when I do close everything, or restart the phone, or clear the cache, or do most of the things websites tend to say to do in this situation, the smoothness only lasts a few hours.

So I kinda want a permanent fix that doesn’t require a lot of maintenance. I mean, with all the horsepower this phone has, I should be able to run just about as much stuff as I want, right? I thought uninstalling some apps and disabling bloatware would help too, but I uninstalled everything I really don’t need and disabled everything Verizon would allow, and I actually don’t think it’s even made a difference.

As a techie, I’m almost ashamed I haven’t been able to fix it. XD the solution could just be a factory reset since I haven’t done that since it was on lollipop, or rooting, but I really don’t feel like rooting and I don’t feel like factory resetting it again (I did that two or three times when it was on lollipop and had the memory leak bug) and setting everything up again.

But if those are my only options, I’d happily do that. Anything to fix this maddening lag. What do you think? Is there a fix? Should I just suck it up and root/factory reset? Should I suck it up and close my apps/restart when it bogs down? Or is there no solution because no matter how beastly of an Android phone you have, is lag and stuttering never ever going to go away unless you aren’t a power user?

Thanks for baring with my novel of a question. I do really like your website and I think you may be able to help me! — Zachary

Solution: Hi Zachary. That Android OS is “laggy” is not new. This has been an issue that Google has been trying to address for years now. The issue may be happening on high end phones like Samsung’s Galaxy S series, but it is more apparent in underpowered, more affordable Android devices. Needless to say, lag, or the perception of it, is real but it shouldn’t be that much of a hassle for most Galaxy S phone users.

Unlike iOS devices which, by design, has to stop other processes in order to devote all resources once a user touches the screen, Android permits running of other apps and services. This means that the moment you touch the screen, Android treats it as just another task to be completed. If your device is already running low on RAM the moment you touch the screen, you may perceive a “lag” of some sort. This situation, as you may have already known, is what we call memory leak. Memory leak issue became more pronounced in more Android devices after Lollipop was introduced but we’re receiving more and more reports from our community of indications that it’s also happening with Marshmallow update. If this problem is indeed occurring in devices running Marshmallow, the best thing that we can do as end users is to report whatever bug or symptom we encounter and hope that Google can roll a fix as soon as possible.

As far as troubleshooting on user’s end is concerned, nothing changed much. Really, if the true reason for the lag problem is memory leak, there’s only so much that you can do about it on your end. But since you’re wondering if there’s something that you can do, here are the basic tips that you can try.

Isolate the cause

Whether the real reason for the stutter is memory leak, firmware, or app, knowing which is which is a priority. The thing is, this is easier said than done. An average user may not have the technical savvy or tools to do the job properly. In your case, you want to check first if one of your apps is the reason by restarting the device in safe mode.

Alternatively, you can also run third party diagnostic apps like Trepn Profiler, App Tune-up Kit, etc to get a quick overview of potential issues in your mobile data/Wi-Fi network, GPU loads, RAM usage, among others.

If you can’t establish the reason for the lag, proceed to the next step.

Delete or disable apps and services you’re not using

If you haven’t used an app in the last 2 weeks, chances are you don’t need it. If you have a lot of similar apps, removing them from your device may remedy the situation. They don’t only clutter the storage device, but they may also be running services in the background that consumes RAM faster than designed.

Wipe the cache partition

Forcing the phone to create a new system cache sometimes help. Boot the phone in recovery mode and hit the wipe cache partition option to do so. Wiping the cache partition can be done regularly or as often as you want so it won’t hurt if you do it right now. Here’s how it’s done:

  • 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.

Free up device storage space

After some time, your phone’s memory can get cluttered. Creating breathing space for your device by freeing some space may also help, especially if the phone’s primary storage device is running low on space. If the main storage device, where the OS is stored, is almost full, the flow rate of data can slow down.

Turn off unnecessary animations

Because Android is designed to run as many apps and services as possible, lowering down events or tasks being processed at one time may also work. If you are fond of allowing special effects or animations, now is the right time to turn them off. Try to check your launcher settings to see if there’s a way to tweak some animations or extras you can live without.

Do a factory reset

If nothing appears to change after doing the stuff above, performing a factory reset may not hurt. Sure, this step is a hassle, but doing it may be the only solution left for you.

Factory reset can get rid of firmware bugs that may have developed after installing an app or an update over time. Turning the device into a clean slate will tell you if the issue is within your end to fix or not.
