S5 Refuses To Start Up

Problem: Good day I have tried all of your techniques but my Samsung Galaxy S5 refuses to start up. The ‘Samsung Galaxy S5 powered by android’ logo appears, the screen flashes grey then it goes black, it then vibrates as if it’s starting up then the whole process begins again. I left it while it was doing this for 10 minutes and it turned off completely and won’t show any signs of life until you plug in a charger, it is also extremely warm. I have had this phone for approximately 4 years now. It had a cracked screen a year ago that has been repaired. Do you have any suggestions that I could try?

Solution: Try checking first if the phone will compete the startup process while it is connected to its charger. If the phone starts this way then you might want to try replacing the battery first. If the problem persists then remove the battery and microSD card (if one is installed). Press and hold the power button for at least a minute. This will discharge the phone circuit and clear its RAM. Reinsert just the battery then go ahead and see if the phone will turn on.

If the problem still occurs then follow the steps listed below. Move to the next step should the problem still occur after performing a step.

  • Start the phone in Safe Mode. If you are able to access this mode then the issue could be caused by an app you recently downloaded. Find out what app this is and uninstall it.
  • Start the phone in recovery mode. Wipe the cache partition of your device.
  • Start the phone in recovery mode. Do a factory reset. Take note this will erase your phone data.

If the above steps fail to fix the problem then this might already be a hardware related issue. I recommend that you bring your phone to a service center and have it checked if this is the case.

S5 Working But Screen Not Turning On

Problem: I have dropped my phone a bit in the past and it was working until now. I’ve had it for a year and ab it. When i turn my brightness down the screen flickers multi colors and when i leave it to turn off it flickers as well and when i turn it off and on it does it. When i turn my phone on i can hear it vibrate and the lights come on but just not the screen. The screen is blank. I hear notifications come as well. All the lights work but the screen. I’ve done a factory restart in hope that it will work but it is still occurring. Please can you tell me how to solve this and what the problem is. Thank you

Solution: This problem could be caused by a defective phone display or a loose connection between the display and the motherboard of your phone. For this issue I recommend that you bring your phone to a service center and have it checked. There’s a possibility that the display assembly will have to be replaced if it is found out to be defective already.

S5 Will Not Charge

Problem: Hi, my Samsung Galaxy S5 will not charge. I have tried a different charger, tried aligning the charging port on the phone, I have tried to see if it was an app with Safe Mode, I have also tried manually clearing my cache by pressing the power, volume, and home button all at the same time. I am at a loss and now my phone is completely dead. Please help!

Solution: Try cleaning the charging port of your phone using a can of compressed air. Make sure to remove any dirt or debris that’s stuck in this port as this can usually cause issues with charging. Once you have made sure that the charging port is clean you should also try charging the phone using a different charging port.

Should the issue remain unresolved I suspect that the charging IC of your phone might  be damaged. I recommend that you have your phone checked at a service center that does board level repairs.

S5 Randomly Restarting

Problem: Hi, I am having issue with my Samsung Galaxy S5 randomly restarting. I have done troubleshooting by starting up in Safe Mode, and the problem still persist. I restore by doing factory reset and the problem still occurring. I am confuse as far as what causes this restarting dilemma. Please help I really need his phone to be working as this is my only way of communication and a gift from my brother. Thank you!

Solution: Since you already checked the software side it’s time to troubleshoot the hardware side. What you can do next is to try to replace the battery with a new one. This allows you to check if your old battery is already faulty and causing the problem. If the issue still occurs even after using a new battery then we might be looking at a hardware component inside the phone that is failing to work. If this is the case then I suggest that you bring your phone to a service center and have it checked.

S5 Not Booting Up Solution

Problem: Hello Guys, Kudos for the great work so far. i am not here to ask a question but to add how i solved mine after the help here did not apply to my issue. Samsung Galaxy s5 had boot up issues. No response at all. however, when a charger was connected, the battery icon would flash briefly then be gone for a while, pop up again like that on and on. I could boot to recovery and download mode initially. later, only download mode. This led me to believe it was a firmware problem as discharging, wiping cache and switching between 2 batteries being used  were to no avail. Almost flashed a stock ROM unto it but the loss of user data was a problem. I finally noticed that one of the batteries had a black scorch mark on the terminal. scrubbed it clean with a metal and did same for the the phone terminals too. That solved the problem!!!…. The same worked for the other battery. though it had no scorch mark, scrubbing the terminals made it power up the phone. So that’s a solution  i didnt see here. Hope it helps someone. All the best and thanks for your help.

Solution: Thanks for sharing this tip which can serve as a useful guide to our readers.

S5 Keeps Switching Off And On Repeatedly

Problem: HI My s5 keeps switching off and on repeated. I have left the battery out the phone overnight tried to wipe cache. It switches on shows me the Samsung screen shows me the service provider screen and again the Samsung screen black with little blue dots or strings. After this screen it switches off. Tried rebooting without my sd card and SIM card but still nothing.

Solution: Try starting the phone in Safe Mode. If you are able to access this mode then the problem could be caused by an app you installed. Find out what app this is and uninstall it.

If the phone still switches off and on even in Safe Mode then follow the steps listed below. Check if the issue occurs after performing each step then move to the next if it does.

  • Wipe the cache partition of your phone from the recovery mode.
  • Start the phone in recovery mode then do a factory reset. Take note that this will erase your phone data so make sure to have a backup copy before proceeding.

S5 Randomly Turns Off

Problem: Good morning, My Android will randomly turn off on me, by having the screen go black. It will sometimes turn back on when I press the power button, if that doesn’t work, I have to pull that battery out and put it back in to get it to power up. When it does finally power up, the battery will say it’s critically low even though the battery life was much higher before the phone went dead. And when I plug it in to charge, the battery life will go up fairly quickly at first, then slow down to usual charging speed. This issue never happens when I am plugged into a charger the whole time. Just when I use it without being plugged in, and with multiple apps being used.

Solution: Try starting your phone in Safe Mode first then check if the issue still occurs. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it. If the problem occurs even in Safe Mode then proceed with doing a factory reset. Make sure to backup your phone data before doing the reset. Once the reset is complete don’t install anything in your phone yet. Try to check first if the problem still occurs.

If the above steps fail to fix the issue then you can do the following steps listed below.

  • If your phone has a microSD card try removing this as this could be causing the problem.
  • Try using a new battery.

S5 Copy Data From Water Damaged Phone

Problem: Hello. I stupidly took my Galaxy S5 into the pool with me and so caused some water damage (okay, destroyed the phone). I’m getting the phone replaced and all, but I’m sad to say that I had weeks of game progress saved on the phone with no cloud backup! Is there a way I or a proper technician would be able to remove the flash drive and copy the data?

Solution: The contents stored in the internal storage of your phone are protected which means that the phone has to be turned on first before you can retrieve the data. Removing the on board storage of the phone is a risky process and you won’t be able to copy the data stored in it. You might have luck having your phone checked at a service center capable of doing board level repairs.
