display turns on and off - Optimus 7 General

Hi all,
5 days ago I've updated my phone. Now I'm experiencing a strange problem. My phone turns the display on without any reason! This happens when the phone is attacched to my pc, when it's beeing charged or when it's in stand-by, in other words EVERYTIME! Some time this problem doesn't occur, the phone stays in stand-by, but I can't identify what is the relation...
I tried to downgrade by reflash the firmware to the old version... NO LUCK!
I tought it could be a problem (bug) with notification... but right now my phone is clean, no app, no contacts, no accounts, no calendar, NOTHING!
What can I do?

I've got the same problem. When I plug into laptop I cannot turn off phone. After push the power button more than 15sec, on display shows "Goodbay" and after few seconds phone turns on a starts up.
I think that it must be it. This is not problem ora nay damage of phone but maybe little bugs in system software. Don't worry

Well, when the phone is plugged in to a pc or during the charge, you CAN'T turns it off! That's because the software must manage the charging process.
The strange part is that I did NOTHING to my phone (except the update but now I just rolled back), so I don't understand what is the difference from before!
I think I'll send my phone to the repair center... at least it's still under warranty...
cheers

Wizard not turning on. Doesn't boot.

Hello, a while back I posted a charging problem, which turned out to be the Mini-USB and Wall Charger was bent, and before that, the Mini USB outlet in the phone broke entirely. Well, another problem has arisen, as finally got a new charger yesterday, and worked perfectly. So, I shut it off, and left it to charge overnight. Now, the problem? All of a sudden, it refuses to boot. Held down the power button for 5 seconds, 20 seconds, and a full minute. Nothing. Any suggestions?
~Infinity
nothing AT ALL? or the screen turns on and gets stuck?
if nothing at all happens, try the battery jump start method
Well, after constant trying at starting the phone, I managed to have it boot after hours. What happened? During the boot,where it displays Windows Mobile 6, a line appeared, and the phone darkened, and then crashed.
What the hell.

....................And how can I hard reset when it doesn't boot, and whenever it does, crashes during it?
Anyone that's here help?
I'm currently having the same problem with mine. Hard resetting didn't work for me but you may as well try it.
If you can get it to start booting for just a few seconds you can hard reset it without loading the operating system. As soon as you get it to turn on, hold down the Wifi and Voice command buttons (one's on the left, one on the right). After holding those down, press the soft reset button (the little button on the right that you can press with your stylus) very quickly and release it. If you hold the soft reset button too long, it will perform a regular soft reset and you'll have to start over, so do that quickly.
A black screen should come up and tell you to press your send button to hard reset your phone.
I have similar problem,It's turn on to the logo that's always shown when boot and then it show the logo till it discharged.I tried hard reset,but it's still the same,i post 2 topic's in this website and no one help me
i too am facing the same problem, i was able to start it a few times but it crashed after a few seconds each time. i m gonna charge it all night and see if it starts. right now all i m getting is the red led. i really hope someone finds a solution soon.
With me it was my battery that caused the problem. Try it with the battery of another wizard. Succes, Rietje
ok so i charged it for more than 12 hours and my wizadr still didnt start.
I then got a NEW BATTERY and my wizard turned on within the very moment i pressed the power button.
So any one who is facing a similar problem should try a new battery.
Yea,this is a second time when i have this problem.I both A new battery,BUT IT STILL THE SAME!!!
First time when i both a new battery it was working fine,but now the battery won't help

try a battery frm a friends phone. u ll be sure that the battery u r using works fine. if ur phone still doesnt work then u need to have it checked.
i have same problem,,and i use T-Mobile MDA Vario
is it just battery problem or not?and if the PDA inactive it can still charge or not?
and i usually use blackberry charger to charge my PDA,is it ok?and is there any possibility my PDA can't work again?i hope not
pls help me..
Well for starters, charging your phone overnight will probably damage the battery over time. It's only the newer phones and batteries that are able to withstand extended overcharging times without serious damage to the battery. With older phones including the K-JAM/MDA Vario, the battery is meant to be charged till its full, and no more. If you overcharge it, you run the risk of damaging your battery and possibly the phone too.
If a new battery hasn't fixed your problem, the problem lies in your phone's mainboard.
Try charging your phone from a USB port on a computer to see if anything happens.

Anoying bug or Falty phone

Hey Ive got two really annoying problems I was wondering if anyone had a fix or can tell me my phone is falty. And if they have tried the "leaked" froyo has it been fixed so I dont have to send of my phone.
1. Sometimes when I turn off my phone, when I try turning it back on it appears with the loading circle for a few seconds and then turns off again, I cant get my phone to turn on again until I charge it or connect it via usb then when the battery symbol is on press the power button.
2. USB connected on the notification bar when it isnt connected
1) the phone went into full shutdown, if you see that battery charging screen
2) definitely a defective phone, take it back to the store for an exchange, it should not be doing that at all

Thanks I will get it sorted but #1 happens when i have quite a lot of battery , When I shut down to say restart it wont turn back on.
that's is another reason why it's not good, it should not be doing that (defective)
when it goes to sleep mode, it should not turn off completely
on a normal phone, when it goes into sleep m ode, you can still charge the phone, without the battery bar thing showing up
Ok thanks yer if you havnt heard of it I better get it sorted quickly I should be still in the 28 day period so should eb a straight swap thanks.

I've had these issues also, its not because its a defective phone. Just bugs somewhere. I only had them on a certain firmware, no idea which one now but flashing to a new firmware and resetting the phone and they have both gone.
I use to get the usb connected continuosly cycling as if i was connecting it and then unplugging it etc etc even though of course it wasn't even plugged in.
I'd simply just reflash the phone or reset it, bet it will fix it.
There are so many little bugs in these firmware versions.

My Galaxy S5 won't start up... (black screen)

Hi everybody
I have a problem with my Galaxy S5 (no custom rom, official)
I normally used my phone, I locked it. But, after about 10 mins I tried to unlock my phone, but nothing happens
I tried to reboot, nothing happens. I tried take out and put the battery - nothing happens. So I searched on Google and tried some keys combinations, but nothing happens. My phone has about 80% battery. I tried to charge it in the charger, but nothing is happening (black screen, no notiffication light). Also I tried to put off my SIM and SD Card, but nothing happens
Do you have some skills in it? Can you help me?
Few days ago, I faced the same problem..
http://forum.xda-developers.com/showthread.php?t=2853472
Then I'd to take it to the Samsumg store.. And they return it back in 2 days and said me it was a software problem..
I wanted to do a recovery reset, but i can't boot my phone anymore, also the Kies doesn't see anything, so. Did you really think that is a software problem? Because my phone won't vibrate at boot. So maybe it can be a hardware prob :/
EDIT: Phone started blinking red light... (nottiffication), I tried to charge it, but nothing...
Mate as mentioned early, same problem I faced..
It'll be better, if you return it to Samsung customer care..
You seem to be saying that the problem occurred unexpectedly. So presumably this isn't subsequent to a flash error, newly installed app or a trauma (dropping the phone, etc).
First ensure that your battery is charged, plug in the phone to a charger as well and try turning it on. If at all possible, borrow a battery from a friend's S5 or go to a store and borrow a battery for 30 seconds to confirm that the battery isn't the issue.
If the problem persists, then remove the cable and battery. Then put the battery back into the phone and press and continue to hold in this order, the volume down key, then menu key, then power key. Hold all three until the screen powers up (about 5 seconds). If this doesn't work.. the most likely problem is a damaged power key - try pressing hard or "wiggling" it to see if that makes a difference.
If you still can't start the phone, then see if a local cellular repair shop has a "jtag jig" that you can borrow. Or you can buy one on Ebay for a few dollars. When this jig is plugged into the USB socket, the phone should automatically restart.
If all of the above fails (which is unlikely), you would seem to have a hardware problem or unknown origin. Which would be very unusual. If your phone is under warranty, make a claim. Otherwise get an estimate to repair it.
.
If I hold all 4 buttons at the same time and connect the phone to PC, PC recognises the phone for a few seconds. Well, maybe not recognises, I cant see it, but it plays the same sound as if connected flash drive to pc. However, everytime it disconnects within a few seconds...
I´m in the same case, but I was flashing the Galaxy S5 with the four files ROM and the pit file using Odin3.09. All the process ended well, but after rebooting there apeared one Screen sayin something like "Some files at this phone are encripted and there can´t be modified......." so I did a manual reboot and take off USB cable and from this moment the phone don´t do anything but giving a sound when I plug USB to computer cable and I can see new COM --> Qualcomm HS-USB QDLoader 9008, and there repeat a loop.
I´m still looking for a solution, but it gives me that there is time to change phone.
Possible Fix
This thread is old but idk if this was ever solved, so in case anyone else ever has an issue like this. My Gf is still rocking this phone so i've had a little experience with it. The phone wont turn on or charge. I got it to work by sticking a flat head screw driver and prying it fairly hard against the bottom of the battery (the side closest to the charge port) and forcing the battery harder against the metal contacts. While pushing the battery I turn on the phone and it starts right up and continues to run even after letting the pressure off. I've noticed this happens every few times i take the battery out, but this method has never failed for me turning the phone back on. Hope someone finds this helpful.

weird, youd think that bending the tabs out to force contact with the battery better would do the same trick fwif

Can't turn on the brand new YD206

Hello,
I received the YotaPhone 2 (YD206) today.
The box was sealed.
When I tried to turn on the phone, it didn't start. I thought it was empty so I put in on charger for 2 hrs.
After that I tried again , but still nothing happened -- i was holding power button multiple times, as long as 5 minutes at the time, but there was simply no response -- no vibration, no sound, screen remains black (not turned on), anything at all.
I tried different chargers as well (Xiaomi and Samsung one) -- they weren't working with this phone either.
When I connect phone to a PC, I just hear sound that something is connected (I saw installing drivers notice first time I connected it), but nothing happens at all. I don't see the phone in my computer or anywhere else.
Is there way I can fix this somehow? What else can I try?
Thanks!
You can try unlocking the bands like described here.
Not sure it will help but you can at least try.

Sounds like the phone is defect. The only thing I can think of is that it somehow freezed up and you will need to let the battery drain so all power is off the phone and then try to recharge it. Draining the phone completly without screen use can take up to 7 days.
I finally managed to turn it on,by keeping it on charger for whole day and night and after a couple of attempts it was on.
I thought battery voltage was pretty low which prevented it from turning on.
I used a phone for a day, completely discharged it and then recharged it to 100% again. I thought everything is gonna be good now.
Then I wanted to upgrade to Lollipop, I decided to use YotaFlasher to flash EU KitKat first, and that worked fine. After that, I used OTA update to download Lolipop.
Download finished, and I was offered to "restart device and apply update", but as soon as I confirmed, the device went off and I can't turn it on anymore. What the heck is happening with this yotaphone? (battery was at 97%)
I can't turn it on, restart, put in download or recovery mode, get it to charge or get the screen on. Also PC don't recognize it *AT ALL* -- not even sound that something is connected. It looks completely dead (again).
Any ideas what I can do to fix my new problem?

Samsung Galaxy S7 Edge Not Turning On

Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.
Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?
This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.
sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?
I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon
Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?
As mentioned in the description, I have unfortunately
