Help with troubleshooting - bootloop, calls restarting phone, wifi won't turn on - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

I've been having some problems with my Galaxy S5 recently after ~2 years and some change of owning it. I'm stock rooted on the original ANCG KitKat version.
The problem: If I power off my phone, it will cause it to go into a bootloop, not going past the first screen (Samsung Galaxy S5, powered by android). I haven't found a reliable way to fix it from the loop, but I usually just remove the battery, wait, and try again until somehow it just works and boots up. This is extremely problematic because sometimes my battery runs out and after charging I'll have to go through this game of chance again until my phone works.
The next problem also adds to this frustration as well. When I attempt to pick up a call, my phone will sometimes just not work and restart itself. This leads to lots of confusion and I can't call them back for some time because the phone is stuck in a bootloop.
In the few times that I do get my phone to actually boot up, everything works fine except sometimes my Wifi just doesn't work. It gets stuck on "turning on" where the notification drawer quick setting icon is dim green and never gets to the turned on full green state, eventually just turning itself off (no green color).
I haven't done a factory reset or any real troubleshooting yet, as I'm a bit worried I won't even be able to boot up the phone and I don't have the time yet to spend a full day fixing it. Any help would be appreciated, thanks!

The calling problem may be caused by the google dialer app not being set as the the default phone app but as for the other issues i have no idea a factory reset is a good start though

unfortunately I had the same problem but I have marshmallow but the factory reset helped with the not booting up and see a big difference with the battery

Phone crash after battery died!!

my battery was running low, (and coz poor battery issues with JPY), i didnt notice when it switched of. normally i use the power button to turn the screen on to unlock, but instead i realised the phone had been off as it was now booting up...it booted up fine went into the homescreen and then vibrated once and powered down.......now it was powering down for a long time and occasionally there were vibrations and the lights on the home keys were constantly on. the screen was black. i got home and tried to charge it but the progress bar showed no progress on charging, i tried to switch it on but it would go to startup screen vibrate cupla times and power down. so eventually had to do a hard reset in recovery mode. tried every option but in the end had todo it by wiping data.
now the thing is, is this supposed to happen? if ur battery suddenly losses power ur whole fone will screw up?
for future ref if ur battery dies dont try to switch ur fone on until u got some charge in it and use the home key to put screen on..
Sounds like it could have been faulty firmware .
JPY does not have a significant battery drain problem per se .

Black screen, vibrations and no boot after restart
Hello! I had almost the same experience (Black screen after reboot and occasional vibrations) only mine refused to boot even after memory wipe and after flashing new roms.
Was your phone rooted? Because I think rooting a 2.2.1 rom (XWJS3) was the beginning of my nightmare. keep in mind that the phone was working like charm for two months. This was the second time I had a problem. The first time the phone started after performing a factory reset by itself!
In case this happens to you next time and for every non experienced galaxy player (like me) reading this:
Don't panic! Blank screen, vibrations and no boot doesn't necessarily mean a hardware problem. Finally I managed to fix it flashing eclair and repartitioning with pit512. Now I'm a happy XWJS8 user
And a question for the experts: Any clue why this happened? Is it really a rooting issue? Can a cheap Chinese battery from ebay cause this?
everything was stock on mine, no root.......maybe thats why i could recover it??!!
Maybe! and I hope the reason is faulty firmware as JJEgan says. If this is true, your phone will be fixed by the next update.
I was very urge... the same happened again. It's been a month of smooth functioning and now after a simple restart, the device doesn't boot for absolutely no reason (Stuck on black screen constantly vibrating). Since my phone wasn't rooted, and I haven't seen many people talking about a problem like this I suspect:
1. Faulty hardware (for a few devices including yours and mine)
2. A Bad app.
Contacts Vanished
Hey Everyone
Im having similar problems, i updated my sgs to the js7 version of froyo, then rooted it with oneclick method. this was as i got the phone a month ago. Its been smooth sailing since then. But last night the phone powered down and wen it loaded up it had no contacts, my sms where still there but all the apps had a force close issue none worked. so cleared the cache in recovery. Still nothing so i did a factory reset and once loaded up. i formatted the sd and internal within the settings option. So the phone was now clean. I then connected to pc luckily had backups so installed titanium restored all my apps n settings. Using kies restored my contacts n thanks to an app called sms backup i restored those.
So all was well and worked again. I didnt restore the apps i had installed within the last week to make sure it was not a faulty app. I was happy, but now tonight it did it again. No contacts again.
Pls help
Any suggestions
That's exactly how it started for me. One month after rooting froyo 2.2.1 Suddenly everything force closes and the device hard resets by itself. I reinstall all the apps and then after one month and performing a simple restart, it refuses to boot. Stays in a black screen and vibrates every some seconds. I flash a new rom but does the same. Problem solved after repartitiong and flashing original eclair with pit 512. Reflashed a 2.2.1 rom and everything works perfect (the phone now is unrooted and with a nice clear stock rom). But then after one month again (!) I realise that some videos refuse to play. Trying to restart and craaash. black screen, vibrations and no boot. Did the same again (repartitioning and flashing) and now I wait for another month to pass and lose an hour of my life to do the same again. No idea why this is happening. Is it possible that rooting messes with something that stays faulty after restoring the file system? is there an app that we all installed and caused this mess? please this is the most serious problem I've red in this forum and still a mystery. I believe this thread should be sticky and we all share similar experiences because this looks completely random!

Verizon i815 random reboots

Had my Verizon 7.7 i815 since 4-30 and love it except for one issue - it reboots at least
once a day usually when its connected to the charger.
I need help figuring out if this is a hardware issue so I can just exchange it or if is
software/other issue that I can resolve myself.
When it reboots it goes to a black screen with a single white dot in the center.
It is playing the reboot jingle when this happens.
Sometimes it will bootloop and I have to press the power button for a few seconds to
reset the tab.
Honeybar is installed and AdwLauncherEx is the launcher.
I have tried booting to stock recovery and clearing the cache and did a factory reset - didnt help.
The tab is rooted.
I also removed the Sandisk 16gb microsdhc card after a reboot at 5 am because I had read about users who were having issues with their tabs until removing or switching out their sd cards. The tab went without rebooting after that for 19 hours until I installed
Hidebar. After installing hidebar the tab rebooted twice within a minute so these two instances may be because of that app. I uninstalled it after that and went back to
Honeybar.
I have only experiened a white dot reboot when trying to swap the phone.apk (it was a never ending reboot). I otherwise haven't had it reboot on me. I don't use any bar hiding apps.

Just to be clear my tab was having the reboot issue long before
I installed hidebar - I only installed hidebar tonight and have
owned the tab for a week.
I am however able to cause the reboot consistently with hidebar.
Well the reboots started again after almost an entire weekend reboot free.
Going to exchange it at Verizon for another 7.7 tonight.
Good luck! hopefully the new one is error free.
I've had the same issue with mine, also a vz 7.7.
It was happening in a loop the other day and I managed to capture a video of the entire sequence.
I don't actually think this is a reboot but instead seems to be more of a screen and radio lockup.
I get the little dot in the middle of the screen. After 20 seconds or so the tab goes back to the lock screen. Once unlocked it has to re-connect to either Verizon or Wifi.
I tried disabling the wifi and 3g/4g networks and this seemed to improve the situation but yesterday I was able to get it to do the same thing with the radio's disabled so probably not chip related.
I'm still within my return window I think. Seriously considering returning the thing mainly due to this problem and the lack of ICS.
Had a GT8.9 previously and even though the screen isn't quite as nice it was a pretty great tab and cost half as much *and* can access the awesome AOKP ICS rom.
--tr
Yep, development for this tab is non-existent at the moment.
I'm stickin' it out tho and hoping for CM9 sooner or later.
Same here. I can't find a pattern to what triggers it. The first time i was installing a bunch of apps from my computer via Google Play (not tethered to PC). I pull my microsd and sim and it continues for several cycles. Did a bunch of the stuff you did also w/ clearing the cache and actually the first time i couldn't get it out of the loop (it would actually get into the desktop where it looks like it would be ok, then suddenly screen w/ the white dot in the middle and looping again). Never got close to depleting the built-in storage, so that's not the factor.
Sometimes I can get it to stop by turning it off by holding power down and turning it back on again. It doesn't happen a lot, but it's freakin annoying when it starts.
I don't have honeybar, but am running ADW.
Wow, good to know others who are going through the same issue...I thought I was the only one! I still have the reboot loop issue even after performing a hard reset. For me, the reboot loop only occurs when I'm on a cellular connection. If I'm on wifi or on airplane mode, it doesn't happen. I'm well past the exchange/return policy so this is extremely irritating.
Personally, the most frustrating thing is that my tab will be fully charged at the start of my day, then in my bag for the morning while I'm at work and then, when I take it out to use it, the battery is completely drained because of the reboot loop!!!
I'm hoping an update (ICS?) will fix the issue but I'm not holding my breath for it...
Same issue here. I am rooted, and originally thought the reboot was from Gesture Control app (awesome app!) when hiding navi bar. But after reading this thread, I'm not so sure.
I've only had the reboot loop once, here is my setup when it happened....
-had just unplugged from charger after full charge
-Mobile data was off, Wifi was set to sleep....never when plugged in..
-The device kept rebooting, so I powered off, went into recovery, wiped cache. I also turned off Gesture Control app functions (not sure if this was necessary however). This seemed to stop the reboot loop.
Would be nice if we could keep gathering info on the conditions that cause this, and potentially find a solution. It sucks having a dead tablet because of this issue.
My 7.7 does the same thing. I don't use the tab constantly, but I do notice the reboot on a fairly regular basis. Same symptoms as everyone above, except for me it doesn't go into a loop, it just reboots once with the white dot and then comes back fairly quickly, so not really a full reboot. I don't see the Verizon & Samsung splash screens, just the white dot then the login screen.
Mine is not rooted, has the stock ROM, and does not have any UI enhancing apps or mods. It's pretty much stock other than having applications installed, and nothing that really runs in the background because I have Advanced Task Killer kill auto kill every 30 minutes.
Not that big of an issue for me right now, but would definitely like to see it resolved.
gawd! It doesn't happen a lot, but when it does it's friggin annoying. Yes, it's the white dot and doesn't show the full bootup splash, kinda just goes to the desktop again seems ok for a minute and then boom- black screen w/ dot in the middle and it starts over again.
This last bout was pretty bad and it didn't respond to shutting it completely down by holding the power button and letting it boot again, which has sometimes fixed this in the past when it's looping like this.
Can't tell what is causing it, at first i thought maybe a live wallpaper, the 64GB sandisk microsd card, or a faulty sim (sometimes my tablet says SIM not inserted, even if it is). I tried changing all of those but it still happens. I haven't found a pattern of usage or other type of trigger to make it do this though.
I've only ever experienced this when I tried adding in the mms and dialer app from the GSM 7.7. Otherwise my tab has been rock solid.

[Q] Screen Black / Auto Powered Off Frozen?

I seem to have the most bizarre issue that started happening last night. Ive been running XNote v3 and AEL kernel fine for a long time now.
Whenever my screen turns off (when i hit the power button or the timer runs out to turn screen off) The phone will after x minutes, either auto reboot or turn off (without shutdown animation)
It then remains off black screen and you do not know this unless you try use it again as you cannot power it back on at all, no sound and the phone is off as if you call you get voicemail.
Anyone any ideas what it might be?
I cant work out if it is software/ hardware related as nothing has changed software config wise and i have not done any updates.
I was thinking of maybe going to a stock kernel and see how that lives.
Its very easy to replicate and the only way to bring the phone back to life is to take the battery out.
If i am using the phone its perfectly fine, no reboots, freezes etc. Its only when screen is off.
OK since no one replied back but a lot of people viewed i thought i would provide an update.
Since factory resetting it
changing battery
wireless charging
removing sim
removing SD card
changing rom
changing kernel
changing back to stock
remove root
boot loader etc
all failed! a new replacement motherboard fixed the problem. i am unsure what caused the fault as it was working perfectly for over a month.

Note 4 freezes while charging after lollipop

I tried posting this in the Sprint thread but haven't gotten any answers yet so perhaps I'll have better luck here. I pasted both posts to show the initial problem and what I did (essentially I factory reset). I'm still having the same problem where my phone will freeze while I'm charging it (about 2-3 times/week) requiring a battery pull. Anybody else seeing this problem or have suggestions on what I should try? Thanks.
-----------------------------------------------------------------
Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
--------------------------------------------------------------------
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.

Hi there. I have a Canadian Note 4 (W8) with Bell, and I am having identical issues.
While charging over night, I find my phone stuck on "Samsung" logo, with the bubble animal still running. Holding down the power button does nothing and the only work around is the battery pull. I noticed that it also gets warm (assuming from the screen on time?)
First tried cache wipe - no fix
Factory reset - no fix
Cache wipe again - no fix
Aaaand today I came into work late

Did your issues first start after you upgraded to lollipop?

Definitely after the upgrade.
While on KitKat, it never happened (1 month ownership). But after upgrading to lollipop, it has happened 4 times (6 nights since lollipop).
Have you figured anything out with your situation? Woke up this morning to my backup alarm and the Yellow Sprint screen on my phone.
I guess I'll have to try another factory reset and if it still happens try and get a replacement. It just doesn't seem widespread enough of an issue to be a software bug with 5.0.1.
Very frustrated. I did another factory reset but the issue still plagues my device. It still only occurs once or twice a week but when I hear my old clock radio alarm in the morning I know when I look over I'll see the yellow frozen Sprint Spark screen. I am completely out of ideas and guess I will need to have it replaced under warranty. I'm hoping Sprint won't give me a hard time as this will be very hard to demonstrate.
It definitely appears to be a software issue as it never happened before I upgraded to Lollipop but there must be more to it or others would be complaining.
If anybody has ideas please let me know. Thanks.
Response to Note 4 Freeezing while charging
I have found that after turning the quick charge feature off the problem is not happening. Hopefully this is fixed in 5.1
I'm having the same issue even after turning quick charge off..def a lollipop bug, never experienced this on kk.
I know its not the BEST option, but after taking the update to lollipop, sometimes left over kitkat files can make the system poop out. Sometimes a factory reset will take care of the leftovers. But of course, then you have to set your phone up again
If you've tried this or plan to to, let us know the results.
(When i first took the update, my heartrate monitor sensor was always on, so i did a factory reset and it fixed my problem).
Solved with workaround!!!
I faced this "sleep of death" too after updating to Lollipop. I had to pull out the battery almost every time after charging. Very annoying! I noticed though that my phone never froze in my car while charging. Thinking about the difference I realised that I keep my phone awake in the car while charging using Macrodroid (which I love anyway to automise all kinds of things). I made a simple macro which keeps my phone awake while charging and another one that returns the phone to normal while on battery.
While charging: Trigger: Power Connected; Actions: Keep Device Awake enabled & Screen Off, Constraints: None
On Battery: Trigger: Power Disconnected; Actions: Keep Device Awake disabled & Screen Off, Constraints: None
Off course there are alternatives available to Macrodroid that should be able to do the same.
My problems are solved, with and without fast charging. I hope this will help some of you as well.
same problem here
Ive tried turning off fast charging option on the powersaving mode
And also tried the option on developer mode, the "keep device awake while charging"
And even flashing dofferent firmwares from sammobile through ODIN and installed custom roms. These options doesnt resolve the issues on freezing while charging..
I think turnong off your device while charging is the only option..
Im using note4 N910C..

Thanks a lot, Mate. I'm trying your workaround now. Will report later if it works on my phone. BTW, so, are you sure it is a just a system issue? Definitely, isn't a hardware problem? Did you fix it, after your post -a month ago-, installing, for example, lollipop 5.1.1 or Cyanogenmod 12.1? I'm on 5.0.1, SimpleRom V4. Of course, mi device, N910C, is rooted.
Thanks again.
With lollipop 5.1.1 the problem is solved for me, even without this workaround.

I'm having similar issues as you guys. I found out that my phone will only perform normally when I charge it with my laptop USB port which I think is around 0.5amps. Anything above that, even a 1amp charger would cause the phone to freeze, reboot and turn off and not turn back on. The phone has been in repair 4 times and the problem is still there. Now every night I'm forced to charge my phone with my laptop which takes an age instead of the fast charger that came out of the box.
Currently my phone is still freezing and rebooting when I'm out and about and the only way I can get it to perform normally is when I plug it into my laptop. This normal functioning would only last whilst the phone is plugged in.

S5 SM-G900F : Black screen/Boot loop; Help?

tl;dr at the bottom
Alright so I'm out of ideas on how to fix this phone, couple of days ago my mom came to me complaining that her S5 was giving her trouble. When she handed me the phone, it was in a bootloop of showing the Samsung Galaxy S5 screen, playing the theme and vibrating afterwards then rebooting. I took out the battery and tried to power it on, it ended up successfully booting into android. So from here, I figured there must have been some malware on the device, I downloaded Malwarebytes from the Google Play Store and ran a scan on the device. However in the middle of scanning, the device turned off it's screen and rebooted. (Malwarebytes found 2 malware on the device at that point) So now I'm convinced it's most likely malware and eventually removed all the detected malware on the device. I gave it back to my mom thinking it was fixed.
Moments later she came back saying that it's still giving issues, my first thought "wdf, it was working wasn't it?". I looked at the phone again, and tried to wake up the device using the power button. The 2 soft keys at the bottom lit up however the screen was still black. At this point, the phone was still working fine, the only issue was the screen wouldn't wake up. So I decided to do a battery pull once again to reboot it and it results in the bootloop once again. I did some googling and found various solutions to this, one of them involved wiping the cache from recovery, so it tried it. Booted into recovery and wiped the partition cache (i think that was it), after it wiped and was about to reboot, I noticed a brief "error icon" just before it rebooted. After this point I could not boot into recovery at all (it would just show a black screen and I would assume that the phone turned off) and it was still in a bootloop. It was only after trying to turn on the phone after trying to boot into recovery that the idea of the phone wasn't off and the screen was just black entered my mind. (Because usually if the phone is off, you can turn it on by holding the power button, the phone would not turn on until after a battery pull)
So at this point, it was late at night and I was tired. I left the battery out and just went to bed. The next day I tried to turn it on again and to my surprise it booted up fine but I was skeptical. I had a theory that the device would work fine as long as the screen remained on, so I set the screen timeout to 10 minutes and kept it on for probably 30 minutes while I continued to google. Since it stayed working during that period of time, I thought perhaps locking the device triggers the issue. I turned of "Power Button instantly locks device" and proceeded to turn off the screen using the power button. When I tried to turn it on, it was back to the same problem (black screen, device is working fine, soft keys lit up). I did a battery pull once again in an attempt to reboot and now it was back to problem #2 (boot loop, can't enter recovery). At this point in time, I considered doing a factory reset but since I couldn't enter recovery, I'd most likely have to re-flash the stock firmware.
Since I didn't have much experience flashing android devices (I personally only flashed 2 or 3 devices ever, all of them were successful but I still didn't really trust myself), I had it sent to a local cellphone company and had them try to fix it. Eventually I got the device back, but they were unable to fix the problem (they tried to flash a stock and custom rom). Now I'm back to square 1, the phone is still in a bootloop, no sound, no vibration this time, I don't have much experience with phones since I've only owned 2 in my life. The phone seems to be soft bricked pretty good, I've still got 1 more trick to try (full stock firmware flash) before I call it quits, any ideas?
tl;dr
- device is stuck in a bootloop (issue 1)
- i was able to enter recovery mode once, now it's not accessible
- download mode is accessible
- the device has been able to boot successfully a couple times, but then it has another issue.
- device's screen would not wake up after turning off, softkeys still worked, everything else still worked. (issue 2)
- the device was sent to a local phone repair company to fix (unsuccessful)
- currently device is stuck on issue 1
additional notes
- device has not been dropped or wet
- device has been owned for more than a year without problems
- this problem was recent (3 days)
- no sd card
- dark screen was turned off
theories
- screen could be malfunctioning or defective somehow, but then if it can show the bootscreen and download mode screen fine it seems unlikely also since it's been working fine for over a year
- it's a software issue of some sort, but has already been flashed by local phone repair to no success, then again I'm assuming they just did a basic recovery flash and called it quits
