black screen & blinking blue led - Samsung Galaxy S7 Edge Questions and Answers

Hi,
I was charging my phone earlier and when i returned to it, I found it to be stuck on a black screen with a blinking/flashing blue led. I've tried all common suggestions such as leaving the power button + volume down key pressed for 30secs, then power + vol up for 30secs, then power + vol up +vol down for 30secs, then power + vol up + vol down +home for 30secs, and also many other combinations to no avail. The battery will be near 100%, and I fear it'll take a week to drain. Any suggestions? Has anyone experienced this in the past? If so, how long did it take for the battery to drain?

[Q] Power on/Charging problem

Hi,
I just got a used T-Mobile HD2. Tried to power it on by following methods, but none of them works:
1. Press "power" button; no reaction;
2. Press "vol up + vol dn" and "power" button, no reaction;
3. Reset using the yellow button underneath the battery and re-power, no reaction;
4. Charging it using wall charger, the phone start to vibrate periodically and the screen start to flash with "stick together" page, but the charging led light is still OFF.
Is this a hardware problem? Anything else I could try ? Thanks.
With the charger plugged in and on, try the vol up and down together and press both and power button, hold down till the 4 colour screen comes on then flash a new raido and then a new rom, use a 50 radio
It could be hardware only time will tell

Hello,
Suddenly, my phone turned off and won't turn on back. I didn't tried anything, just happened. Few weeks ago, it was with a problem of don't charge correctly, i connected the cable, but instead increase the battery power, decreased. 2 hours charging, decreased 10 %. Then, i removed the battery and put back, until get back to normal.
I tried Vol Down + Button power, Vol Up + power button, Vol Up + Vol Down + Power Button. Don't respond.

Nexus 4 Red light Problem

Hey, my Nexus 4 died a month ago. i have tried many things from the internet, and none of them worked.
When i'm holding the volume down + power button, and inserting the USB cable, the red light is coming up, and it's Solid Red Light, and after about 10-15 second, it disappear. i sent it to one private lab, and they didn't succeed to fix it.
what can i do??
*Note: i'm going to give the device to another Lab - but i still want to hear you people
Simulate a battery pull by holding volume UP and power button simultaneously for one minute, see if that helps get you back running to the point you can at least charge it up and factory reset.
I've had the Red light of dead yesterday because i had critical battery level and didnt charge
I responsed immediately and pressed volume down + power and it entered

And then connected the charger and pressed power button again to select START
It booted and started charging

Screen blank, blinking blue led, can't force reboot - and never been flashed!

My wife woke up this morning to an unresponsive phone. It's been on the charger all night.
The screen is off, and the led blinks blue about every five seconds.
power+volume keys has no effect - neither power + vol down nor the standard recovery- or download mode combinations, even holding down for half a minute or more.
The phone hasn't even been flashed - it's still on the original ROM.
Never seen this on any Galaxy device before, I'm completely clueless.
Have you seen this before? Any ideas on how to force it to power down?
Thanks!
force restart is power button and volume down for 10 sec if that's not helping you have a broken phone.
Thanks. As I wrote, force reboot didn't work.
But it seems I was wrong - it did work, but I had to hold the vol down and power buttons pressed for over a minute!
So problem solved, for now.
