So yeah... like the title says, I'm having trouble charging. Basically I plug the phone in (powered off), and it will turn back on. I turn it off with it still plugged in, and it powers back up. Also, if I turn the phone upside down (screen facing down), the orange/red charging light goes off, but turns back on when it's right-side up again. I'm VERY confused with this... Would this constitute an exchange at the Sprint store?
its haunted. Boo~~~!!!!!!
my hero does the same thing and i dont think there is anything wrong with it

Are you sure you are powering off, or are you putting your phone to sleep? There's a difference.
On mine, if I physically power off the phone (hold the red button down for about a couple of seconds and select Power Off), then the phone will not turn on when I plug in a charger (or sync cable).
However, if I simply push the red button without holding it for two seconds, the screen simply turns off (I put the phone to sleep). When I plug in my charger (or sync cable), the screen will turn on (the phone wakes up).
Just in case you really are powering it off. There is a built in awake interrupt set to monitor power connect. To manually activate it connect , disconnect, connect, ( fast ) the power cord to the phone. It should boot. So if it's doing it then your power application to the charger, is noisy. Get a zero crossing switched power strip and use it's switch to power on the charger.
Mine has always booted back after I plug it in if the battery dies or I power off intentionally for some unknown reason. I didn't realize people intentionally turn their phones off any more.
Guys, I can't turn on the device since 2 weeks ago. IIRC, the battery was empty and hence the device turn off. I charged it overnight but couldn't bring it up. I have tried the below(which is not working):
-Hold power button for 30 seconds(or more)
-Hold power button + volume down with charger plugged or unplugged
- Hold power + volume up+down butoon
- Left 2 days of charging
- There were blinking in LED for 5 times in random day when i plug in charger but still couldn't boot or boot to bootloader
- Remove and put back the battery
- Tried different charger (ori and non ori)
- Tried USB charger through PC and can hear the "usb plugged in" sound from my laptop but can't see the storage from My Computer. Tried holding down power button and there was a sound that alerts usb plugged in/out
ANy idea what's wrong?
Hello to all,
can someone help please.
my battery discharge completely and my phone turned off, after that I can't to power on. When I use power button I only hear vibe and nothing happens, also same problem is when use combination with volume buttons. When charging phone via adapter and USB cabal via laptop nothing happens - no led charging red light or picture on the screen that battery charging.
I managed with combination power + volume button to go in bootloader mode (on device manager on PC it shows "Android boot loader interface")) but on the the screen of phone nothing.
Also sometimes when use combination of buttons I managed to power up red led for signal that battery charging sometimes but when I plug off cable it still flash, it is on.
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?
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
