[Q] My power/lock button just stopped working....

Okay, I have a LG Optimus Black and I'v had for a few months now and yesterday afternoon the power/lock button just stopped working. I took the battery out and put it back in, and it wouldn't turn on. I found out a away to turn it on using my charger and the power/lock power. Can anyone explain what is going on with my phone?
Thanks

The power button pad has been internally worn down by repeated use.
Sent from my LG-P999 using XDA

Okay, so my power button is screwed?

Tried another ROM already? Maybe you just got a SW bug, which doesnt interpret the buttons correcly...
But I would say it's screwed...

No, I didn't think of it. I went through heaps of hassle with data and stuff flashing the ROM I have now so I didn't think of it Could you suggest and good ones for my phone? and with good battery because my battery isn't charging properly or fast like it used to or not at all. Oh and the ROM I currently have is CyanogenMod.

I would personally suggest you go with Zeus over Marvel, Both are great ROMs ofcourse ,however i had more available ram with zeus which could give us an edge when trying to play games..and the thing tat i liked abt Marvel is that it is totally custamizable

Dont turn this into a battery/ROM discussion thread. There are several of them. I would suggest you to simply flash stock SW, as you would have to do it anyway, to bring back the phone on warranty...

Okay arun_pms, I'll try Zeus. Do I look it up on this?
Sorry NOOBY0815. Yeah, I'm thinking of taking it back and get a new one or a whole new phone. But yeah, I'll flash it back to stock if what arun_pms said doesn't fix my problem.

Now i see the advantage of Samsungs hardware home button to its galaxy lineup as an alternative to wakeup the phone.

Yeah, I like Samsung's android phones.

[Q]SGS maybe bricked ? i could use a little help.

Hey guys.
I used to have a phone like this now i moved to S3, i'm used with a lot of roms etc.. so i'm very familiar with it but my friend brought to me one what has some very strange errors ? first of all the screen didn't turn on but the phone turns on and the touch buttons on the bottom either. So we decided to use my old sgs and put the motherboard in it. Meanwhile we found out it has already opened and got a new screen ( who replaced didnt even glued the screen to the phone ) and who replaced it he succesfully broke the digitzer cable ( we have some spare parts so we can change). Anyway we gonna connect all the parts correctly and now the question. As i mentioned we put the motherboard in my old sgs it works but it have a strange problem. it can't turn on it always brings up the battery screen ( when you plug it to charger when the phone is turned off it), its like the phone starts to find out the battery percentage the little loading goes on the battery shows up and then imadeietly turns off. I can put in download mod it already got a new stock rom and if it's plugged to usb it turns on. It do this with an other battery too. So i appreciate any help and thanks anyway to reading this

galaxy note completely dead!! help!!

hello everybody!! I have a GT-N7000 with stock rom and 3 days ago it has become completely dead! there was 50% in the battery, so after 10 minutes i came and found it turned off so i tried to turn it on and it turned on but it froze at the samsung logo screen and tried rebooting 3 times but it didn't work. and now its completely dead it acts like its water damaged but it isn't. So after all that I went to Montreal GSM for a fix but they diagnosed the problem to be water damage so I told them okay fix it, and when i came to get my phone back he told me that this wasn't the problem! so now i have my phone with me and dunno what to do with it!could it be the mother board?and if its the mother does anyone know how much does it cost to replace it in samsung service center in montreal? Thank you guys!!!
yeah and two more things I tried another battery but nothing worked
and there was a screen showing up during rebooting and something strange was written on it " some custom roms might fail the system" somthing like that. i'm not sure cuz it only showed up for 2 sec.
thank u again

Motherboard is pretty expensive. No download mode also? Make sure there is a charged battery. Remove the battery and reinsert it. Press volume down + home + power. Anything at all?

[Q] can't boot

Hello xda, I just want to ask what did happen to my G1, I'm just using it ordinarily everyday but a few days ago something happen, it cannot boot but only led lights flashing, I can't even reach the recovery or bootloader, is this a hardbrick or something? I'm using a froyo rom I forgot what rom it was and I also using the right radio and SPL combo required for that but I don't know what happen, It just can't boot. Help please.

Is it just blue led? If so then yes its bricked and you need JTAG, if not you may be OK, but as to what happened that's hard to say
May be a battery issue but with LEDs flashing less likely, try to get a PC to recognize, try charging over night and testing with PC again, try booting without SD or sim, try any button combo you can

no not blue

Can you get a PC to recognize it and are you able to get a new battery?

Hello again dem, since my phone can't boot, my laptop can't recognize it, and I'm confident enough to say that my bat. don't have any problem, I do have a universal charger and my battery are charging using it, one strange thing, I also have a cabled charger for my G1 which has a led light as well, I've tried charging it using that and the led light of my charger are blinking which means it is charging but the led light of my G1 was not blinking, I really don't know what happened to my G1, I hope you could give me some help, any way I tried to search for what JTAG is, but I think I can't do it since I don't have any ideas when regards to the hardware aspect of android, I'm even a noob on software aspect of adroid devices.
P.S.
I forgot to say this, sometimes another strange thing happen on my G1, whenever I try some button combo to reach either recovery or bootloader, my buttons and keyboards have lights but my screen is totally blocked out.

Sorry to say but I'm thinking your motherboard is shot. Send me a pm when you get a min. May be able to help you out

hi again dem, I don't think its on the battery, call me crazy or anything but still remember N70? I have one, though their battery differs in size yet their gold energy conductor or whatever they call it is just the same. Since the battery of the G1 are easily drained I need to have two battery but since I'm from Philippines I have hard time looking for battery of my G1 that's the reason why I used my N70 battery on it as a backup whenever my G1 runs out of its juice. Before I can successfully use my N70 battery ( I just place a paper or anything on its side and lower portion to make the fit right) but since the problem on my G1 occurred even my N70 battery are useless and unusable because it still don't boot. I know my problem is a weird one but I'm looking for a way to recover it without modifying or replacing its hardware. Don't have money for it. Hope you could help me with this. thanks.
P.S.
I never run any problem before using my N70 phone, its maybe because they have the same voltage which 3.7 the thing is their capacity. For you to believe me I attached here the photo of my G1

Sony Xperia SP black screen without any reaction after intense RAM usage

Hello there everyone! The case happened to me today morning and I have no idea what to do. Basically the whole problem happened after I was using the browser, opened 3 windows at the same time , one of them was a video and the other 2 were google images. So the phone couldn't handle all these and the whole screen just froze. I locked up the screen which I still regret because I could have just turned the phone off and thought that locking up the screen would work since this has happened to me numerous times before without having these consequences.
I have tried the Simulated Battery Pull trick but it didn't work no matter which volume button I tried along with the power button. I held both for about 20-30 as written but the phone didn't react. Strange thing is when I charge the phone it's showing that it's charging the battery (yellow light) so the phone isn't completely dead as it seems. I would like your opinion about this and a proper solution cause I don't want to bring it to the service (even though my phone is only 4 months old )
Should I wait till the battery completely drains to zero (which could take 1 or 2 days ) or should I try fixing it myself?
Please help me ! I have no idea what to do :crying:

This all happened because you set LMK to very low value
If you want to reboot your device then press and hold off button located behind back cover

LMK stands for Low memory killer.In order to understand this you need to know how android manages ram.
Basically whenever you close an app with back button the app still runs in background.Android does this so as to not to waste free ram available.Whenever you run heavy app the LMK is waked to kill those app running in the background

Thank you. And is it possible to adjust this without rooting the phone? Don't want to lose my warranty for it.
Of course only answer if this isn't meant to be too much off-topic.
