Any ideas?

You may have to force it off and back on again. Warning this is not something you want to do too often; press and hold the power button until the device shuts down. Upon restart you may find that it takes longer than normal. This power down is similar to pressing and holding the power button on a pc and may cause your device to need to scan it's memory like a pc would after such a shutdown. Just relax and wait. Once restarted restart it again, normally this time just to ensure all data gets back in line.

This happened to me to this morning! I went in to ATT store expecting to get a new phone.

THE FIX::: Press and hold BOTH the volume key and power button for 8-20 seconds and your phone should restart. The help guy said this is the equivalent of removing the battery in older android devices with a removable battery.

Hope this helps!

Worked perfect!

Just a clarification.... I had to hold down BOTH volume buttons and the power button to accomplish the reset.
Thanks for the information. My Galaxy S7 is only 4 days old and it blanked out. Grrrrr!..

i'm stuck here with black screen, blue flashing led... and no buttons responding. inserting charging cable does nada, nor when into the pc. i'd been having random reboots... that wouldn't complete in the rebooting. i had to soft reboot quite a few times today, but i couldn't even get the thing to stay on long enough to call tech support at optus - i thought that perhaps an app needed updating and that was a likely cause of the crashes, so went to update all in the play store... and here we are. sorry, new here so hopefully i've followed protocol, but any ideas, other than hard resetting, would be graciously appreciated.


(ps it's been a fantastic day in my samsung world- the reason for not researching what best to do in the first place was that my galaxy slate was updating / restarting for like two hours for no apparent necessary reason at the same time!!!. finally home and on the not-samsung-made pc which works, so far. definitely not normally anti S either, just pi$$ed off at the moment, i've had s3 and an s5 before and only had one hard reset in 5? yrs - potato)

Do you have an SD card installed in either device? Try booting up without one.

Re: galaxy s7 blank screen blue light flashing?

at the moment it won't do anything at all though - is it safe to just yank the card / sim out while it's on?

Re: galaxy s7 blank screen blue light flashing?

and thank you

Re: galaxy s7 blank screen blue light flashing?

Taking the SD out while it's processing may cause corrupted data but at this point that would probably be a minor inconvenience compared to a device that isn't working. As for your SIM I would think it would only be affected if it was being written to which it most likely isn't so probably not a problem. Once you've removed them you may have to hold the home button like you would on a pc to get it to reboot.

 

[Hayden Charles]

awesome, thanks, will try that now (took the sim and card out already but only tried power button... no effect0

 

[Hayden Charles]

tried every button combination, for 7s, 20s, 1m, with sim in and completely out.... nada :-(

You might need to send it in for repairs if nothing works.

 

[Hayden Charles]

power ran out - any advice before plugging in and turning back on ? (ha, now... i say that)

Try gettiny into recovery on bootup. Press home+volume down+power button. Do not let go until you see the recovery menu. Then wipe cache. Be careful you don't select wipe phone.

This is what worked for me. It opened a boot menu with 5 options and I selected "normal boot." Be careful NOT to select "factory reset" if you don't want to wipe your data!

Try volume down, power AND the front button all at once until it reboots.

Mine's been doing the lock up too, but started after I changed the settings to have photos automatically go to my SD card rather than the device. Does that make sense that this would happen?

I'm new to Samsung, having had BlackBerry devices before.

TIA.

I can vouch for this method. S7 screen just went white after using YouTube, then it went black. Held down the volume down, power and fingerprint button for about 10 seconds. A blue screen appears, press volume down to restart phone. Restarted no problem
