hey guys
my phone (Samsung A40) has a problem. sometimes when my is turned off and i plug it in it shows no reaction. when i press volume down to start (because the power button is broken) it begins to vibrate in intervals. only when the battery is empty the vibrations stop. there are also some times, when i plug my phone it, the display indicates that it's charging and it is possible to boot up the phone.
maybe i should also mention that i opened up the phone the replace the battery and the volume flex cable because the whole unit didnt work. now when phone works, everything works normally except for the power button.
why does it sometimes start to vibrate and sometimes just works fine? how can i fix this problem?

Hi guys, I hope I can type this coherently.
I have a g3 wizard that I have flashed many times over the last year or so. Lately the power button has stopped working. I can get the phone to turn on by plugging it in, and then holding in the camera/voice buttons and THEN hitting the power button. It goes into the rainbow screen, and I just soft reset via the hole on the side. At that point it is on and running fine, but the power button does nothing.
The power button does nothing at all unless I plug the phone in, and then only if I go to bootloader. It seems to work just fine to do that-which is what is stumping me. I thought the button was just broken. The charge/battery lights do come on.
For now I have it set to never turn off, so I try to make sure it doesn't run too low. The battery life seems ok. Any tips? I want to be able to put the phone to sleep again...
thanks
Hi , i have problem with my u8800. Sometimes it won't turn on after power off.
It turns on after some time, but sometimes it dont responds when im trying to turn it on.
Sometimes helps plugging to charger without battery but not always. And it's rebooting sometimes.

How long u press power button ? Just make it a litte bit longer like 6 sec
About 10 sec, but sometines it's not responding. It's little better since i flashed aurora.
Your button is like mine which is getting old. I need to press 3 times sometimes more to turn on phone or turn screen. My advice use volume waker mod.
I was just surfing through the net, I left my phone on bed & went to the bathroom, came back and found that the display won't turn on. Pressing the power button caused the back,recent apps buttons to light up but that's it. Even the LED notification lights work whenever a notification came.
Note : I think the phone turns on properly when I hold down the power button bcz I hear sounds, the led blinks, the phone even vibrates. But the display stays pitch black all the time.
What I tried :
Take out the battery, leave it for a few minutes then put it back on and try to turn on the phone.
Take out the battery and hold down the power button for a minute then put the battery back in and try to turn on. This time the phone turned on but when I pressed the power button once normally to turn off the display, it won't turn back on.
Try to go to recovery mode (Power+Home+V. UP). This worked once too but when I cleared cache and rebooted the device, it didn't turn back on.
Try to go to download mode (Power+Home+V. Down)
Plug the phone to my PC through USB cable, PC detected it but nothing happened.
Sometimes the phone turns back on normally but after a while it dies again. I checked the battery, it's fine.
hey!
I own a Samsung Galaxy S4. Since today I cant boot the phone up anymore!!!
while watching youtube videos it sudddenly was dead, I didn`t even drop it. turning on again with the power button doesnt work, advanced boot with power button + other button doesnt work as well. only if I reinsert the battery the phone vibrates and it turns on for about 2-3 seconds, the samsun bootloader logo appears and its dead again. I have already replaced the battery with a working one, doesnt work. I removed the sd and simcard but that did not help.
Sounds a lot like a power button problem.
The exact problem is that the button is stuck or shorted, which causes the circuit to be constantly closed. In other words, it's always "pressed".
Please help I was using my phone when the screen suddenly goes off but the phone is on, the screen is blinking (lights up and off) continuously but it stays blank. I can open and close the screen by clicking the power button as you would normally do if you're checking the time on your phone. I tried pressing the power button for more than 15 seconds; tried the volume down + power button for more than 15 seconds, and tried the volume up + power button combinations. I tried it while it was connected to the charger and I also tried it without connecting to the charger. All it does is restart/boot my phone I know because it vibrates, but no logo, no display of the battery charging, but the notification light turns red when connected meaning it is charging. I can connect it to the computer also and it displays my device's model. But all in all the screen just stays blank and just keeps blinking (like lighting up and down). The phone wasn't dropped and it did not get wet by any liquid substance, when it happened the battery is up to 87% and I left the screen off for 4 hours before using it then it happened. I am out of solutions as I can't also reset it as there is no display even the logo and battery charging display are gone. But I know it is alive because I can turn it on and off and connect to the charger and pc. If anyone knows or can diagnose the root of the problem it can lessen my worries and maybe just resort to bringing this to a cellphone repair shop. Thank you. TT____TT
