S5 Not Charging When On Issue

Problem: When I try to charge my Galaxy S5 it does not charge when its on. When it is turned off and i plug in a charger, the battery with a lightning bolt symbol appears and disappears continuously, vibrating each time it reappears. I’ve tried 4 different chargers, each with different adapters, 4 different outlets and i have cleaned the charge port thoroughly. I did the power button solution when one takes the battery out and hold the button for 1 minute, 3 times and still nothing.

Solution: It looks like you performed most of the troubleshooting steps that needs to be done for this particular problem. What you will need to do next is to isolate the battery as this might be causing the problem. Try getting a new battery and see if this does the trick. If the issue still occurs then the next step is to check if the phone software is causing the problem. Backup your phone data then do a factory reset. Once the reset is complete try to charge your phone. Should your phone fail to charge then this might already be a hardware issue. I recommend that you backup your phone data and do a factory reset.

S5 Yellow Exclamation Mark When Charging

Problem: So I started to try and charge my phone and got the dreaded yellow exclamation mark. Sometime it would charge, sometimes it wouldn’t. I then tried a friends charger, it didn’t work, tried a new battery, same problem. I left it on the ‘yellow exclamation’ mark screen for an hour. When I turned it on, it read 1%. But it stayed on 1% all day. I then plugged it in again later in the day and no light to show it was charging or the charging sign on the home screen either. I then cleared my cache following your guide (power, home and volume up button etc) and when it started back up the battery showed 88%. Great! You would think….I plugged it in again just to see if it was fixed and yet again, no charging light or symbol on the home screen. It’s also not being recognised when I plug it to my laptop if I want to transfer files. Help!

Solution: This appears to be a hardware related problem already possibly caused by a faulty charging port or charging port board. Since you already tried a new battery and a different charger you should try cleaning the charging port of the phone next. Use a can of compressed air to clean the port and make sure that any dirt or debris stuck inside is removed. If this doesn’t fix the problem then I recommend that you have your phone checked at a service center.

S5 Restarts Randomly

Problem: Hi, My mobile started to restart few weeks ago. Before it was working absolutely fine. Now it restarts randomly and keeps on booting main android logo again and again. Mobile does not boots up. Then I take out the battery for 10, 15 minutes and then it fix its start up. Please help me in this problem.

Solution: What you will need to do first in this particular issue is to check if the phone software is causing the problem. Try to follow the troubleshooting steps listed below. Move to the next step if the issue still occurs after performing one step.

  • Start the phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are prevented from running. If the phone does not reboot while in this mode then the problem could be caused by an app you installed. Find out what app this is and uninstall it.
  • Wipe the cache partition of your phone from the recovery mode.
  • Backup your phone data then do a factory reset.

S5 Boot Loop After Software Update

Problem: hey. I downloaded a software update and it was successfully downloaded but when I installed it fails. it reaches 20% but then it stops and says error. not just that after it says error it restarts and goes on the logo loop. wtf should I do? lol it’s already the second time that it looped. please help

Solution: Try taking out the phone battery and microSD card ( if you have one installed in your phone). Press and hold the power button for at least a minute. This will discharge the phone circuit and clear out its RAM. Reinsert just the battery then turn on your phone. If your phone still has the boot loop issue then you should start the phone in recovery mode then do a factory reset. Take note that the reset will erase your phone data.

If doing a factory reset fails to fix the problem then you should consider manually flashing the phone with its updated firmware file. Instructions on how to do this procedure can be found at several of the popular Android forums online.

S5 Keeps Restarting Unless Plugged To Charger

Problem:  can’t use my phone unless its on the charger. If I take it off the charger it keeps restarting itself to the samsung screen then it will keep doing that until i put it back on the charger then it reboots up and i can use it.

Solution: You should check first if the battery is causing the problem by replacing it with a new one. If the issue still occurs even with a new battery installed then you should try checking if your phone software is causing this problem by backing up your phone data and doing a factory reset.

Should the above steps fail to fix the problem then you should bring your phone to a service center and have it checked.

S5 Screen Does Not Turn On

Problem: Phone worked fine. A day ago, it started flickering as I turned it on. Then the flicker got a bit “stronger” being a full yellow flash, and it required pushing the home key after the power button. Now the screen does not turn on. Powering the phone on, I can, for a moment, see the screen, my alarm & remote options. The phone was VERY recently given to me, so a master reset was done. Previous owner stated there was a short lag between power button and screen showing. When the screen turns “on” (black to me, but home & back buttons are lit) if I touch the screen, it responds with sound. It’s not set to auto bright, nor is it very dim. I have no accessibility options on, and have tried removing the battery multiple times. ANY help you could be would be amazing. Thank you. *I am guessing on the android version below. I am not sure. It’s whatever came stock*

Related Problem: The backlight on my phones going out. I’ve tried removing the battery and putting it back in, restarting my phone ect…my phone works fine, but when the timer goes out on the light and the screen goes black, I have to fight with it; clicking it on and off, just to get the damn light to come back on to unlock my phone. I can’t asnwer some calls because of this. I have never dropped it, but I have noticed the problems getting worse and its taking longer to turn back on.

Solution: It looks like this issue could be caused by a faulty display assembly. You should however check if the phone software is causing this issue by doing the following troubleshooting steps listed below. Move to the next step if the issue still occurs.

  • Start the phone in Safe Mode. If the issue doesn’t occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Start the phone in recovery mode. Try to check if the issue occurs in this mode. If it doesn’t then the phone software could be the causing the problem. Backup your phone data then do a factory reset.

Should the above steps fail to fix the problem then you should bring your phone to a service center and have it checked as this could be caused by a faulty display assembly.
