phone stays black, button not responding? help - Galaxy S5 Mini Q&A, Help & Troubleshooting

hi, i have a g800f. Sometimes (3 times in the last month) my phone doesn't wake up when i press power button. The last time i received a whatsapp message and then touch didn't worked, the phone didn't respond and then it became black. I had to remove battery and it started up again. An other time i found it like it were off because pushing power button i received no answers, so i did the same thing, removed battery and worked again.
I read it is a common problem of S5 and S5 mini. any way to fix it? maybe i should do a factory reset? anyone has the same problem? sorry for my bad english

It's happening to me too. There is no way at the moment to fix this issue. The only way that i found is to not remove the battery every time just press and hold three buttons together (Volume Down + Home + Power) it will boot you to Download Mode. Just press volume down to restart it.

Yeah this happens to me occasionally, I cant find a better solution to this but removing battery or waiting for 2-5 min.
Android 5 is coming in 2 weeks hope this issue would be fixed and overall performance for S5 mini would be improved.

[Q] Power On: Power Button needs to be pressed a very long time and still increasing

Hello,
for several months now i am experiencing a strange behaviour of my Diamond when Powering on.
After powering off the Diamond in the evening when i try to start the phone next morning i have to press the Power button for a long time (up to about 30 seconds) until the phone sarts booting the OS. Sometimes it needs several attempts until i get it working.
In the last weeks the time i have to press the button is increasing.
I am afraid that my Diamond will be only a brick in near future.
Hard resetting the phone and flashing different ROM's (AZTOR, RTT) did not solve the Problem.
Has anyone in this Forum experienced the same Problem and is there possibly a solution?

[Q] Samsung Galaxy Exhibit II 4G (SGH-T679) Can't Boot

My Galaxy Exhibit II 4G is about a year old, rooted and i have CM11 installed. Everything was fine, I had it plugged in (charging) and i was downloading an app (Camscanner) from the Mobogenie store when suddenly the phone shut off and the battery icon appeared with the loading circle in the middle.
This did not stay on for long as the screen would go off and this would again appear. After pulling the battery and removing the charger, then reinserting the battery, the phone would just flash the SAMSUNG logo in this very same manner.
I am unable to get into either recovery or download modes and when i try this combination (VOL UP + VOL DWN) i get:
RAMDUMP MODE
Cause: Force Upload
I have been reading forums for hours and i have found nothing. Is my device bricked? What can I do to recover it? Please, any help would be greatly appreciated :crying:
What happens if you try vol. up + power, or vol. down + power?

Thanks for replying. Nothing happens. It just continues to reboot like I'm not doing anything. The only way I'll get a reaction out of it is with vol up + vol down
It can be tricky. This post may be clear http://forum.xda-developers.com/showpost.php?p=32437850&postcount=6
The link you sent me to sounds similar to my problem, except I wasn't trying to update the firmware. The crash was spontaneous.
However, neither of those methods work. As soon as I put in the battery the SAMSUNG logo appears, then disappears and reappears and it continues like that... Pressing the power button does nothing, whether by itself or with the volume up/down button
I am beginning to panic
What happens when it's connected to power?

Anyway, after many hours of investigation I discovered it was a hardware problem. The power button was stuck and so it forced it to reboot repeatedly. It also explains why it (the power button) was unresponsive. Disassembling the phone and freeing up the power button solved the problem.
P.s. Your build of CM11 is boss
I have same problem with power button. Had to tweak it hard cause it was so sensitive.
It's the first time it's happened to me. Probably because I dropped it so many times
Strange, ...

I also get ram dump mode error when trying to manually boot recovery.

OK so I'm no expert or anything but maybe my experience with this Model might be able to help you a little bit. I have the same model and it was doing the exact same thing however I haven't rooted it. And I've since corrected the issue on mind particularly it appeared that it was the charge port and/or USB that either had a bad connection or possibly it was boot looped. However with me not rooting the I didn't understand how it could be booted Looped so I started playing around with holding the power button playin with USB things of this nature and what I found was that if I hold the USB to one side either left or right, this allowed me to help a boot farther into it sequence at first to just show the Samsung logo over and over then I could get it to get to the boot sequence about halfway through the boot animation until I finally got to the exhibit screen where displays its model and 4G status. I accomplish this by holding the USB to one side and pushing and holding the power button intermittently throughout the boot. Once I hit the unlock screen unlock the device and I immediately factory data reset it. I'm under the impression that mine was possibly I think that mine was somehow a corrupted bootloader or software still I don't know what caused it to backed up to this day occasionally it'll shut itself down and reboot on me that's why I'm here today I've got all the parts and pieces I need to flash a new rom and hopefully new software the new work over I'll be good to go I also cleaned the USB port made sure that it was still snug to the board all of the good stuff. I don't know if it'll help you but I had the same situation I thought you'd like to know that it was probably not what you were doing with the phone it may just be the software itself with this particular phone see I done nothing that you didn't had the exact same problems. I hope it was somewhat helpful if you haven't gotten it unlocked or re-booted yet. Then maybe just play around with the power sources and power buttons. And see if you can get the same results I did

No responding M7

Hi all,
This morning i check if my bootloader was unlocked, because i wan't to give it a try to root it.
I found out it was unlocked (holding down volume and press the power button)
After that, i rebooted my phone and everything worked normal.
Until a couple of hours later, my screen didn't wake up when i pushed the power button.
The homebutton and the backbutton where flickering (going on and off)
So, i waited for a couple of minutes, but nothing changed.
After (i think) 10 minutes, i hold the power button for a couple of seconds and the flickering buttons stopped.
Since then my phone doesn't repsond anymore. I tried the powerbutton for a while, and with the combination of holding the vol. up and down.
So far nothing helped.
Does anyone know what's wrong, and what i can do to wake my phone from its coma?
Thanks in advance!
Enjoy your weekend. Ben
Did you press the power button for a few second before the soft keys started going on and off? Does your phone show a green battery animation when you connect it to a charger?
If the soft keys started flashing on their own, and if your phone doesn't show any signs of life even when you attempt to charge it, I'm afraid this is a hardware problem which no one can fix online.
let's wait and see what more experienced members have to say.

X Performance Dual DEAD!! Help Please!!

So I have an X Performance Dual, today as I woke up in the morning I used my phone a while, I then went for a run I leave the phone unplugged and when I came back the phone wasn't turning on I managed to turn it off using the power button + Volume up key, after that it booted to the Xperia screen after that it turned off by itself and now is now charging, not being recognized by the pc on flash mode nor fastboot mode. what can I do?
HI
I have the same. Bootloader unlocked. Upgrading XZ rom and now not woring hopefully I can reset somewhere but no led/usb signals at the moment... Hopefully power will trigger a reset deep in the hardware....
press power button and hold volume up button same time for several seconds. You will feel it vibrate 3 consecutive times. This is a sort of reset with does not delete anything. It just seems to fix boot issues. Try it and see if this helps..

Volume down button and power button don't work

Hi All,
I'm having some issues with my OnePlus 3T. Earlier this week ago I noticed that my volume was randomly reducing {it always would reduce to a low setting but not mute} and at the same time I could not use the power button to turn the phone off or to put the phone to sleep. But if I double clicked the power button the camera app would load up like normal and nothing I did seem to effect the volume. Every time I increased it again a few seconds later it reduced.
So today I had gotten tired of the buttons not working and kept trying to restart the phone... after multiple tries I somehow managed to power off the phone. However instead of fixing the problem once it powered up it went straight into the boot menu and does not load up the OS at all. It keeps going into a bootloop.
I tried clearing the cash and booting in recovery mode... both did nothing and just continued the loop.
I'm not sure if I've damaged the volume down button only somehow {in the boot menu, the volume up button works fine and so does the power button but nothing happens when I click the volume down} or if it an issue with the most recent update.
Any assistance in this would be greatly appreciated.
