Buttons constantly and randomly pushed down, help!

Hey,
So after having browbeating my phone for 1½ years (and recently started bragging about it) something major has finally happened. Shouldn't have jinxed it.
Basically, it pushes buttons in random order. The things that happen (and can start to happen all the time, even before I enter my PIN):
Volume going up
Volume going down
Connection manager opens
Camera turns on
Switches between modes while in camera (panorama, burst etc)
I'm unable to try out if I can access connection manager and camera through volume up/down, but if that's possible then I'd say it's a problem with the volume up and down buttons on the side.
Also: I've lost all connection what so ever with my operator.
I recently flashed to Energy Phoenix 2.0 feb 26th build - Sense 2.1 21892 and it worked as normal for 1½ week. Then today I received a text, and then I lost signal and all the button mashing started happening.
It drains 50% of the battery in about 2hrs, leaving me think that it's doing something even with screen off laying on my desk.
Just now I flashed to Energy Leo feb 26th build, 21892 Sense 2.5 version and it's still all weird.
Anyone know what's going on?
UPDATE: argh, clicked the wrong button and lots of text disappeared
anyway. shortly: the buttons stopped working altogether for a short while, and it stopped ****ing around. Then they started working again and the ****ing around resumed. At one point I couldn't navigate away from the volume screen because of horrendously fast changes in volume. I've tried hard-resetting, but it wants to start up the camera the moment i'm done calibrating my pen resulting in canceled "first-time-installations-scheduled-after-hard-resets", with angry red letters.
stoopid phone

I Had the same problema, but worse, i have the same problem with the keys but also now the led of the flash of camera still on
So the ligh is always on, also when the device is off, i dont know what to do because im in mexico and no many people know abaut repair this phone.
I hope anyone can help thankss

[Q] Starting Problems

I encountered my first problems with my Nexus 5, which i am very happy with, about 1-2 weeks ago. After about 11 months of happy, problem free use, without dropping it or anything else, it started misbehaving (about a month with Android L so far). It crashed and wouldn't start up farther than the 'android' screen most of the times. Rarely it would fully boot, but the seemed to go into the lock screen and crash after a max. time of about 1 Minute of normal use. After going through this a few times I checked some forums and found a solution suggesting to repeatitly press the lock screen button while it boots. This solution worked quite good, even though i had go through the process multiple time the following days.
Last thursday evening (today is saturday) though my phone crashed fully once more (just after checking and having an 80% charged battery) , but now the quick hits on the Power button did not work at all. Instead my phone wouldn't react at all. Neither pressing the volume rockers alone or together with the power button would work either. Having plugged in the Nexus though acheived it to at least reach a state which seems to be a more common problem. It has been discussed and solved for many (seemingly everyone) in another thread called '[Q] Nexus 5 constantly rebooting at 'Google' ' (Link to this at bottom). Long explanations and videos of the situation have been given here, depicting my exact situation along with two solutions:
1. Using magnets near the power button (to apparently loosen two magnets used when pressing the power button)
2. Two flick and quickly press the button (for some this had to be done many minutes)
After seeing many (surprisingly) positive reactions to both methods, I tried them myself. I began with the magnet method and without having it connected to a charger it would boot to the google screen twice (note: As said, without a charger nothing happened). First once about as long as when connected to power and once very briefly. This method didn't prevail more than once and i couldn't start it up any diffrently than before.
So next I tried the flicking method and (maybe because of the magnets) it booted al the way to the 4 colored dots flying around. I let go and it crashed once more. I fooled around with the magnets again and tried the flicking method again, without stopping, as other users mentioned a long time needed (15-30 Min.) and after about 20 Minutes I stopped. My Nexus did not crash, but it is now 'stuck' at the colored Dots. I have tried connecting it to a power outlet, my PC and again started pressing the power button and volume rockers, without effect. It has been so for about an hour if not more. I will try to drain the battery and then continue, but if any other solutions are known Please help, thank you!

Update
After having drained the battery completely and then charging it again, the normal 'charging battery' icon popped up. Trying to start the phone, however resulted in getting into the flying dots loop again... I am able to go into fastboot mode, but neither start or Power Off help the situation. Should I go into recovery mode? I would strongly dislike losing all my data....
(Update)
I tried going into recovery mode, but the only thing that happened was that a little android figure, lying down with a red exclamation mark showed up (which should be normal as I recall going into recovery mode before my problems), and a text saying 'no command' above it. What now? I'm all out of ideas and back up plans, except calling google as it should still be under my warranty. But I don't want to give up my data as I haven't saved anything and I don't want to give up my phone either.

Black screen and dead for few minutes

The first day allready 2 times black screen out of no where and afther that no reaction on any buttons.
The first time i waited 10 min or more then the S7 reacted normal again.
The second time i pushed the buttons....
The only reaction is when i press the same time: powerbutton, homebutton & volume button down.
Has anyone the same problem?

I had that issue once with the home button. I had to schedule a reboot through the craptastical built in scheduler that is says it is supposed to optimize the device. Search for restart in the settings.

I have the same sort of problems. All in all the s7e seems very buggy to me. Random crashes (especially in oculus app), sd card is sometimes not recognised and after most reboots I get two error messages (one about touchwiz and one about system proc). I'm not sure what is going on.

My wife's is a black too. I had a similar issues with my s6 last year it was the brightness had been swiped to low in my pocket, I was able to barely see the screen in a dark room and turn it up. No such luck with her s7. Hope someone can offer an idea, I'm headed to Verizon later if I can't fix it myself.

S7 black screen
Verizon did a reset for my wife's S7 to fix it hold down volume down, right side button, and the button on the face of the phone together for 15 seconds. The phone came right back on with all apps and stuff intact. Hope this helps, they said this wasn't the first S7 to come back like this they think it's a software glitch.

Im having the same problem....

Try turning off the App Power saving mode!! This fixed the black screen problem on my phone.

I've got the same issue (sometimes 4 times in an hour, sometimes it doesn't happen for 2 days..!!).
I've tried fixing by doing a factory reset and turning app power saving mode off.
Unfortunately this did not fix the problem. Yesterday I got an unresponsive blackscreen again :crying:
Any ideas how to fix this problem?

This happened two days ago with my wife's S7 Edge. She was using it to text me about dinner plans after work, her screen shut off, and it wouldn't work for several hours. The thing was getting very hot. When she was home and charging the phone the screen started working again for a little while, but with several green stripes down the right edge snd aa flashing horizontal band of grey near the top overlaying the screen image. Then when I tried plugging it into my computer to use Samsung's Smart Switch to roll back from the update she had accepted while at work the screen died again. It has not come on since, not even the stripes, and blue or red LED lights once in a wwhile at random. I managed to use Smart Switch to wipe the phone's memory. Then the program took several hours to download something very slowly and install that - a whole new OS update? That completed, and now the charging LED works correctly and the green stripes and grey band are back, flashing rapidly when powering on. Otherwise no screen function. She is shopping for a new non-Samsung phone now. Ridiculous.

Locked

Hi - i am a newbie to Android and have purchased a Galaxy S7 edge that is running a Samsung authorised Nougat Beta. Forgive me if this is wrong thread but help would be appreciated.
The phone still has 16 months warranty.
I spent a day configuring apps and understanding how to adjust settings etc and was really pleased with how well i had done and with phone and OS. i deliberately left it overnight with a low charge after my days work to see if any charge would be left overnight. Unsurprisingly there was not so had to recharge and boot up from fully powered down. When it came back to life i discovered that under these circumstances the fingerprint reader does not work and the password was required. There in was first problem as password was not recognised. i know 99.99% its the correct one as i use it on another secure site and am pretty sure when setting up Android Pay i needed to enter it to verify fingerprint reading option.
after a lot of head scratching and trying all amnner of variables and alternatives gave up and opted for factory reset. Pressing the combination of 3 buttons did nothing although my understanding was that it should be from a powered off state which was impossible to achieve as power button would only put phone into standby with date and time displayed on black screen. i eventually found 3 button press using volume down gave me a screen which seems to be downloading new software which i am guessing is new version of OS. its been doing it for over an hour now with no clue as to what progress.
can anyone give me ideas how to get phone back to life.
many thanks

*1 Force restart: “If your device is unresponsive, press and hold the Power key and the Volume down key simultaneously for more than 7 seconds to restart it.”
Factory reset:
Switch off your Samsung Galaxy S7 or S7 edge completely.
Boot into Galaxy S7 recovery mode by pressing and holding Volume Up, Home and Power keys at the same time. (Works alswo in the moment the phone force restarts by the method *1 described before)
Release all three buttons when Samsung Galaxy S7 screen flickers and you see a warning sign.
Press Volume Up to continue to the main screen of Recovery mode.

Xtrons PB7639BP touch screen stops working

As the title says, every day or two the screen stops responding to touch, I have to hold the power button for 30 seconds to force a hard restart or put a pin in the reset hole on the front, then it's fine again for a day or two.
I have updated MCU from MTCE_GS_V2.78 to MTCE_GS_V3.40, and Android from HCT_PX5_6.0(20171023) to HCT_PX5_6.0(20171227), also removed front panel and DVD player and re-seated all 3 ribbon cables connecting the front to the main unit (2 small & 1 wide) to no avail, An ideas? or is it just giving up after 3 years?
Thanks all

I'm having the same problem, only thing is now its become permanent. I've tried everything from MCU updates to stripping down the unit to barebones and checking connections. Its not just the screen touch, its the touch panel controls as well. Did you get thsi resolved?

Unfortunately not, sometimes it comes back to life, I quickly play an album, the screen jumps and flashes then goes black, no touch working but music keeps playing, sometimes my whole journey to work is in silence, I'm learning to live with it :laugh:
