My A8 (2018) is not turning on or charging - Samsung Galaxy A8 (2018) Questions & Answers

Last night, I charge my phone because I notice that it was in 8% so plug it in to charge. An hour later, I check the phone if it was fully charge. I use my fingerprint to unlock but it is not recognizing it so I press the button to wake it but it is not waking up. I tried pressing for much longer to see if it wake or turn on but it is not. I tried pressing the Volume Down + Power to see if I can soft reset but that does not work as well. Plug it in the PC to see if it recognize it but it is not. I left it charging the whole night come morning when I woke and tried everything again but still won't turn on.
What could be causing this?

Try, press Power + Volume Up + Volume Down. You should enter in the Download mode. Press the Volum UP button. Now release the button. Now press Power + Volume Down and wait until the logo appears. The system should be boot.

I even tried pressing it for 30 minutes. Fingers went numb. Still not working. I think it might have been drained to 0% and the phone stops receiving power upon charging.

I just went to Samsung Authorized Service Center since it is still in warranty and they said that it is the mainboard that was faulty. They just replaced it right away.

unplug from any cables, hold power+volume down for ~15 seconds. phone should reboot.
if this does not work, try power + volume up, to see if you can get in fastboot
Got it working. I literally tried every button combo I could think holding them for as long as a minute. Went to vzw and the guy got it into to fastboot on the first try... power button and volume up is what he said he did... don't know why it didn't work for me

Xperia Z3 wont turn on

Hello,
Last time i saw something on my screen was my battery that was almost empty. Now when i want to charge my battery i can't see annything on my screen.
I only see a red charging led light left top of my phone.
I tried several tricks like power button and the sound buttons up and down combinations. even the yellow little button near my simcard.
I could get the 3 vibrations but i still see nothing and it won't turn on?
I Even try with the sony pc companion but it won't recognise my phone even with the volume down button,
How can i Solve this problem ?
3 vibration mean you're turning off you phone. When you do that, just plug in and let the phone charging. It'll take a while, when your phone show battery percentage just press and hold the power button again. It might work

No removeable battery and ROM flashing

Coming from the S5, what are the implications of not being able to remove battery to reboot when phone gets stuck while flashing ROMs etc. What is the solution now with s6/s7?
I'm wondering about this, too. I suppose flashing with the battery almost empty & plugged into a low powered charger while flashing would allow for the battery to fully drain after unplugging it? Every phone I've owned had removable battery, so I don't know what to expect.
Holding the power+volume down simulates a battery pull
Holding down the power button for 10 seconds should shut it off too.

I do NOT suggest this at ALL! A dead battery while firmware up/downgrading can be quite problematic, to say the least.

This generally doesn't work with the newer Samsung devices, like S6/Note 5. But volume down and power button does every time as someone already mentioned.
Volume down+power like others have mentioned. Works every time. I found that at times I had to hold the home button as well.

Not if the phone is already powered up it won't. That's as if it's off when you hit that combination.

Remove charger and let the phone battery die, might take a long time depending on how much it was charged
Try connecting the white MicroUSB > USB adapter that came with the phone to something power hungry to drain it quicker
Power off you device and then wait 10 seconds. After waiting press and hold the Volume Up, Home, and Power buttons at the same time
After the phone vibrates, let go of the Power button, while still holding the other two buttons until Android System Recovery screen appears.
Using the "Volume Down" button, highlight "wipe cache partition" and press the Power button to select it.
After the cache partition is cleared, the Galaxy S7 will reboot automatically. This worked for me ans I hope this will help

Run the battery out, once the phone is off it might get out of whatever loop it is stuck in
Then connect charger and power on
Any background info? ROMs flashed? Shady apps newly installed? Rooted?

Red LED should not show when charger is not connected though
Press power button plus volume up and down hold for 5 to 10 sec it will restart ur phone same thing happen with on s6 but not on s7.
I once had to press vol up and down, power and home (that's all buttons) at the same time for ten seconds for the S7 to reboot as it was stuck and seemingly dead. No led on at the time though. But I have disabled the leds in the settings anyway.
UPDATE!
The battery discharged completely(red led was off),first i tried to put it in download mode and IT WORKED!!! But the phone wouldn't turn on because the battery was 0%.I charged it and now it works fine :| I hope this was something software related and not hardware and i hope this will never happen again.Thx for the help guys!

Great
Sounded like it just got stuck, and because you can't take the battery out you have to wait for discharge :good:

Yup ?
Same problem
I have the same issue... Tried to charge my phone with 15% battery and after a few hours it was 8%. Tried to reboot, charge with the phone turned off but nothing was happening ( not charging, not booting up. tried buttons combinations as well ). The led is not showing up on mine because i disabled it from the settings so i'm not sure if it's charging or not. Took the phone to an authorized service on friday so next week i'll be getting a response from them. By the way, the phone is only one week old :crying:

Google Pixe 2 - brick! Can`t charge and turn on

Google Pixe 2 - brick!
Hi. Can you help to solve the problem please.
I have Pixel 2, bought in Canada, used in Belarus. Android 8.0, stock. After almost a month of use, there were no problems.
Yesterday put phone on the charge for the night, cable the cube out of the box. In the morning he noticed that he had not been charged all this time. After a few drones, the cable was also not charged. 10% of the battery is left. I decided to turn pixel off and on. After the shutdown was no longer included - turned into a brick. The pressed power button + volume does not work. Others charges do not work. When you connect to the computer - does not respond.
What could have affected, but I don`t think so:
- on the same day for the first time I connected a flash drive on OTG (not factory, but third-party)
- to charge used the adapter from the Chinese charging (it seems to fit and the earlier oneplusone worked properly)
Help me pliz!
Did you press and HOLD the power button for more than 40 seconds?

yes, of course
nothing happens
We switched many of the employees where I work over to a Pixel 2 or iPhone8 last week, and one of my users came int this morning with this exact issue. The Recover Mode won't allow you to do anything other than view the barcodes, everything else just brings you back to the menu, won't even attempt to boot.
Talked with Google, and their steps to troubleshoot this was not helpful as you can't get to the menu to wipe the cache or factory reset. Have an RMA with VZW as it was bought from them for it. To me, this looks like a hardware issue.
Did you try to charge the phone with another power supply?
Yes
What does it mean after a few drones ?
I have the same problem. I charged it the whole night, but I got only 4%. Now, the battery is getting less and less whether the is charging or not.
I won't even charge when it's off.
Any ideas?
