Many #GalaxyS5 devices around the world are now starting to receive the new Marshmallow update. As expected, not all users have a good time with said Galaxy S5 Marshmallow update. Some of them contacted us to air their frustrations so we publish two of these issues here.
- Screen not working properly after Galaxy S5 Marshmallow update
- Galaxy S5 stuck in bootloop
- Galaxy S5 won’t connect to mobile data
- Wi-Fi issue after Galaxy S5 Marshmallow update

Hi. I bought my Samsung Galaxy S5 about a year ago in Malaysia, and it was working pretty great until 2 weeks ago where it just started malfunctioning (See the videos in this DropBox Link: https://goo.gl/SVLkhj).
This actually started happening after I received and accepted the update to the new Android 6.0.1 update (currently in Europe). After that, all hell broke loose on my phone and I am not sure why it would happen, unless the update was broken.
I have been reading your website and trying to find ways to fix my phone (Samsung Galaxy S5 – SM G900F).
And I have tried the following: Enabled Developer mode, allowed USB debugging, Cleared all the cache, resetting into factory mode, I even tried re-installing an older firmware from the Samware website (the correct one for my phones region and model).
I even went to a Samsung certified technician, and they told me there was nothing they could do because my Samsung was a model from Asia, and they did not have the tools to fix it. When asked what tools they needed, they kindly told me it was the firmware (the same firmware I had obtained from Samsung themselves).
But as you can see from the videos, nothing seems to work and I am running out of ideas on what exactly the issue can be and if it is even possible to fix it.
Thank you for any help/advice you could give me.
Kind regards. — Marc
Solution: Hi Marc. First of all, we would like to appreciate your effort in coming up with videos to give us a clearer picture on what’s going on.
Now, the issue appears a malfunctioning screen at first glance but we don’t think that’s the case due to two things. The first reason, based on what you said, is the fact that everything was working fine until you installed a system update. The second reason is the fact that the first screen that says “Samsung Galaxy S5 Powered by Android” does not show the same symptom. If it’s a screen problem, the Samsung splash screen should also show the same.
We can’t come up with an explanation why the issue is happening other than the fact that the update may have messed up some graphics or screen drivers during the update installation process. All we can do at this point is speculate about the cause but honestly, there’s really nothing that we can think of in terms of resolution. We don’t know as well if this issue is temporary and if a software update can eventually bring everything back to normal, or if the damage is permanent or not.
If a Samsung service center declined to touch your phone, that’s most probably because they see doing it as pointless. If you’ve already tried to manually flash older firmware without positive result, we doubt if there’s anything else that they can try on their end. There’s no other “advanced” software troubleshooting that we can do to fix it ourselves. After exhausting all software troubleshooting on your end, the only resolution for your problem is to have that device replaced.
Hi. I have a Galaxy S5 (SM-900F), which today started rebooting a couple of times. At the same time the battery seemed hotter than normal.
Later in the day it started rebooting but remained in a loop where you see the Galaxy S5 logo and then the (kind of blinking) Samsung screen. After a while it reboots and repeats the same thing.
I did a factory reset through the recovery mode but that didn’t help.
I wiped the cache partition and that didn’t help.
I downloaded a stock firmware (G900FXXU1CPD2_G900FPHN1CPC4_PHN) from sammobile.com and flashed the phone by using Odin.
No change in behavior.
I then tried to boot the phone into safe mode a couple of times but it wouldn’t go in safe mode.
Then after having tried to boot it into safe mode unsuccessfully, I put the phone down and unintentionally left it on for a while searching for answers online. When I looked at the phone again all of a sudden it was in the “optimizing applications” (or something like that) screen. Then it went into the first boot up menu where you enter language, google account etc. All that went fine and then I had the option to restore from back up, which I did.
Having been at it for a couple of hours I was not very confident that the problem was completely solved. Something was telling me there is more to it.
Unfortunately I was right and at that point (so during restore) the phone got stuck and I am back where I started.
I am fresh out of ideas…
Hope you can help… — Anthony
Solution: Hi Anthony. Have you tried observing how the phone behaves after a factory reset, without installing anything at first? We don’t know what you did exactly after a factory reset but if you immediately tried to restore everything, without letting the phone run for at least a day minus third party apps, we highly recommend that you do so. We think that the problem is being caused by something that you install previously and the best way to confirm that is by letting the phone run without apps after a factory reset.
If you modified your phone’s official software in any way, rooted it, or if you’re using a custom ROM, we recommend that you revert everything back to stock. If the problem continues to occur after a factory reset and everything back to stock, then that’s a sign that the cause of the problem is hardware. In that case, your only way out is phone replacement.
Have not been able to connect to mobile data for a week. I have tried uninstalling a battery doctor that I thought was the cause. Other recent changes were a software update to Marshmallow. I think it hasn’t worked since then.
I also dropped the device but it was on the end and not heavy. I have reset the APN. I have turned Airplane mode on and off. I have cleared the cache in recovery mode. I have removed the sim, rebooted, then turned off and re-inserted the SIM. I received several text messages from previous days, but still no data.
On the mobile suppliers website they have a service to send a configuration SMS to set up the data. I have tried several times but the SMS do not arrive.
I have also tried changing the Network mode to all the options. I have tried data roaming on and off.
Any other ideas?
Thanks. — Darren
Solution: Hi Darren. The first thing that you want to do is ensure that there is no account- or billing-related issue preventing your device from using your network’s mobile data connection. That said, you should have called your wireless carrier first rather than contact us about this problem. The troubleshooting that we offer regarding mobile connectivity issues are similar to what carriers tell their customers asking for help. They are in a better position to help you with this case than us since they can double check their network as well as account details that we don’t have access to. There may be a network outage in the area, or that something may have been changed in your account resulting to loss of mobile data connection. A good thing to try to know if this cause of the problem is account related, is by inserting your SIM card in a different phone. Obviously, if you are in a CDMA network, this is not possible but if you are in a GSM network it’s a logical step.
You’ve done almost all of the possible solutions to fix an issue like this so the only step that remains is to make sure that you update the firmware. If you’ve done this already, the only hope left is to call your carrier and hopefully get a replacement from them.
Android version 6.0.1 Since my last update my wifi does not work like it used to. When I would move from one place to another I could check my Status bar and it would tell me what wifi network I was logged into. It would auto connect to wifi networks I had previously used. This was a very convenient feature.
I am very unhappy about the change. Now some networks will not even connect. I read a couple of problems others are having which are similar to mine. When I tap the wifi now app I get this message: “Sorry but Wi-Fi cannot run on your device. Your software version is not compatible, or your phone cannot be verified as a us cellular phone.”
I am a U.S. Cellular customer and the Wi Fi worked find as described above until the upgrade. I am getting very discouraged with Samsung phones because my last phone completely crashed after the upgrade and I had to purchase a new one and it was only about one year old. That cost me dearly. I let it go without a fuss but now after an upgrade on this phone, that is not even a year old, I am starting to have problems. Maybe my choice in phones is not very good. My husband is still using my old Samsung which is about five years old and it works better than the new ones.
Please find a solution for me, but I will tell you I do not want to go through the process of reformatting my phone. Also can you choose not to download an upgrade if you are happy with what you have. — Judy
Solution: Hi Judy. Although updates are meant to improve user experience and fix known bugs, at times, they can also be a source of frustration as they seem to break things rather than improve them. This does not necessarily mean that Samsung phones are to blame. In the first place, it’s not accurate to blame Samsung at all. If the phone or its apps were working properly prior to installing an update provided by U.S. Cellular, it means that your carrier’s firmware is poorly coded, or that there an app may be creating a conflict with the operating system. Samsung has nothing to do with it.
Since you are having an issue with Wi-Fi Now, a U.S. Cellular app, make sure that you wipe the phone’s cache partition first.
This troubleshooting step is usually recommended if you have updated a device to another operating system version or if the phone is having some weird glitches. Despite not having installed the full set of new operating system files, we suggest the you do the following steps to erase possibly corrupted cache on your device:
- Turn the phone off.
- Press and hold the following buttons together: Power, Volume Up and Home.
- Release the buttons once the Android system recovery menu appears.
- Use the Volume buttons to navigate to Wipe Cache Partition option.
- Press the Power button to confirm selection.
- Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.
If wiping the cache won’t fix the problem, the next logical step is to delete the cache and data of your Wi-Fi Now app.
This troubleshooting step goes hand in hand with wiping the cache partition, albeit for targeted apps only. If the issue appears to be limited to a specific app only, deleting its cache and data may easily fix the problem for you. Here’s how it’s done:
- Go to Settings.
- Proceed to Applications.
- Select Manage Applications.
- Tap the All tab.
- Choose the name of the app that has been going rogue.
- Tap Storage.
- From there, you will see the Clear Cache and Clear Data buttons.
Finally, if these two procedures won’t fix the Wi-Fi problem, don’t hesitate to do a factory reset. If you don’t want to do it, that’s on you but there’s really nothing much that you can do for issues affecting a smartphone after an update.
For your last question, the answer lies on the specific configuration of your phone. Carriers modify software of phones so they can add their own features, services, and some functions including a way to decline a system update or not. Most of the time, these types of updates appear as a notification and they can not be rejected. Call your carrier and ask them if there’s an option in your particular device to reject over-the-air update.
