[Q] Problems with power button and no way to fix it, workarounds?

It seems that my power button has died on my Galaxy Nexus, which is a huge pain in the strategical locations. While I know how to turn the phone off should it shut down, I have no idea how to handle anything else. I have my friends CALL ME to be able to unlock the phone and use it.
There are some apps on Android Market that specifically state that they fix power buttons, but none of them work with the latest versions of Android according to the reviews (if there's any I've missed, let me know).
I know that the phone can be turned off using a charger, since plugging it in or out makes the screen turn on. But are there other ways to turn on the screen, since it's a phone and I'm mobile most of the time?
Is there another way to remap the keys on Android? Note that I cannot root my phone, so options like that are not good either.
Is there a way to remotely turn on Android phone with a tablet through some app? Since I'm carrying my Nexus 7 with me and it uses my phones internet connection to stay online. I tried to find an app that does this, but could not find any.
Any help is much appreciated! I do not wish to buy Nexus 4 at the moment because it isn't much of an improvement and sending it back to UK for warranty seems like a huge mess that I would rather avoid for now.
Thanks!

First, try pgm (slide 2 wake).
Secondly, why can't you root the device? Once you have your screen on, you can turn on USB debugging, and use to it reboot to recovery or fastboot.
Third, there's some experience from users that fixed their own device's power button.

Buy a new power button and put it in.

I had a similar problem with my Samsung Captivate a long time ago. I used WidgetLocker and enabled volume wake function. It uses volume buttons to wake the screen. I'm not sure if this feature is still available, but it's worth a try. If it is not, you can ask for a refund. There are also several apps/widgets to put the phone to sleep. I used this combo for a few months before I got a new phone. Hope this helps :fingers-crossed:

I still haven't found a solution and these apps that say they are a solution, do not work on latest versions of Android. Any other options?

download intellicover app from play store. does not require root

i think pgm is the solution, but you have to root the phone

I've managed to fix my power button recently, its a hardware problem. Do this only if you dont have warranty and are comfortable with opening up your Nexus.
Go to iFixit website and follow instructions to dissassemble the Nexus, its quite easy, a few screws and flat cable disconnects. Next, you need to remove your power button flex cable from the motherboard, do this by lifting the cable connector on the motherboard up and pulling it gently out.
Next thing is a bit tricky and you need to have pretty good sight and precision.
On the flex cable the button consists of 2 pieces, the flex cable and the button itself, which is like a black sticker sticked on the flex cable.
I've removed the sticker and the button that is glued to it with a scalpel (careful!!) and I've found actually rust and dirt on contacts (dunno how rust got there, i have expected dirt only), and then with my scalpel I've carefully scratched the dirt and rust of both parts of the button and its contacts on the flex cable. After that I've put the black sticker back on the flex as it was before (if it wont glue tape it with a small piece of tape) and return everything where it was and assemble Nexus back togeather. And voila! It works!
Keep in mind that I didn't have warranty so it was either open up and try to repair or toss a $200 device. Also, I'm not responsible for any damage that you do to your phone, this is just a brief description of my power button fix. Hope there will be more successful repairs :fingers-crossed:

I had to use volume_wake, while waiting for replacement power button. But this feature does not present on stock roms.

I believe i've read about remapping the hardware buttons; if you're interested, search google. I personally prefer and use smart screen on. I just wave over the proximity sensor and the screen turns on.

Try procedure described here: http://androidforums.com/samsung-galaxy-nexus/700265-power-button-not-working.html#post5797688.
I was very skeptical, but it indeed worked on my phone. Power button started to act normally again! I was amazed!

This would be the easiest thing to do if you're already rooted

Glad to be of help :good:

Solved the same problem with dj_chapz suggestion posted here http://forum.xda-developers.com/showpost.php?p=41282390&postcount=8
After I split in half the button I found oxidized contacts with green and black scurf. Cleaned it with little amount of ethyl - works perfectly!

I just did this repair and I have large clumbsy fingers. thank you! I just had to remove corrosion between the button contacts and around. i dabbed nail polish remover (i'm not sure if that is a bad idea or not, but it got my phone working!) and did a little bit of scraping. on my sch-i515 there was a some clear plastic folded over the back sticker part that i had to get up, then i was able to get the black part up without having to fully remove it.

How to access internal storage when power button is ripped ?

Hello,
I have a Samsung Galaxy Nexus. Yesterday, power button has stopped to work. Nothing was happened when I pushed it.
I tried to open the device (my mistake ) and I tried to see if there was a problem. By opening device, I have accidentally ripped the power button component. So, now it's not connected to the nappe.
Logically, it's impossible to start device now without that connection between power button and nappe.
My problem is that the internal storage of my device contains a lot of photos that I would like to save.
Do you know if there is a way to get these photos ?
Thanks by advance for your help.

boot
i had that problem with another phone....which had a work around
but you may not like it.
1. you may be able mess with the pins in micro usb to get it to "trick" itsleslf on (idk if itll work for this phone, dont really wanna risk frying the phone too)
2. buy a new ribbon online. i took mine apart to paint it . and luckily this phone has a ribbon that slides and locks onto the board instead of soldered on
3.idk what bootloader you have but yours may have an option to take the battery out. *button press comb.* then you can get into download mode(which wont help) but could bring you into the bootloader....unlocked of course.
otherwise....
~*option 2*~ is the best course to take...and they are cheap

Hello,
Thanks for your answer.
I took option 2 for the moment and I bought power button nappe on internet.
I wait to receive it and i will try the operation of last chance lol.

assembly
When I put mine back together. The sticky back to the buttons wouldn't hold to put it back together.
I used a razor....clean it up and scrapped the sticky back to some Velcro I had.
I would hope they send it with the ?double sided tape? Needed to hold it on.

Zenfone 2 power button sticking

I circled the switch in this picture (I posted this on reddit with the source, i can't post outside links here. Sorry for broken link, i don't have enough posts for proper links) imgur . com/JWUOnVc
Anyway, the switch gets stuck down and if I accidentally press it then the phone will just turn itself off and I can't use it until i get a pen/something small and put it in the little slot to pull it out, press it again, then pull it back out. It gets stuck all the way down, and my warranty is void due to it being over a year old, disassembling it, and unlocking the bootloader. I really like this phone, however this stuck power button is driving me crazy. Is there anything I can do to fix it? I really don't want to disassemble it to the point of removing the battery, but if I have to i will. Any way I can fix this?

That picture is useless , cannot make anything out.
Can you describe where you press ?
Is it the white rectangular piece at the top?
If it is and this sticks in when pressed ?
Then it's a collapsed switch internally.
You would just be bodging it for a short period if it is ,send it in for repair
Can you send better pictures, so can get a better picture of its legs which take pressure on the pcb..and its actual circuit?
If you know someone good with electronics, you could get them to put a minute tiny reed switch to its circuit and place it somewhere with a bit of space..then you could use a magnet to switch on outside the device.
Depends how much your phone matters to you

Same problem here, my power button is stuck, I have to use the phone without the back cover. I use the double-tap for screen off/on but I can not switch off the phone.
It seems the button is a small SMD and not easy to replace on the motherboard, button looks like this: https://fr.aliexpress.com/item/For-...wer-on-off-button-flex-cable/32804672233.html

Open front or back to resolder batt connector?

I read conflicting info on how to open the tabpro. My daughter's TabPro 8.4 is bootlooping. I want to resolder battery connector and possibly replace battery if it turns out to be in need of replacement. Any authoritative answer whether to open from front, separating glass from bezel, or remove the back? Thanks!

To me, the back was the easiest to open. Just use a (plastic) prying tool and start from the MicroSD card slot. By turning the prying tool slightly while inserted, you'll pop out the plastic tabs that hold the backcover attached. Just mind that the tabs are stiffer around the 3.5mm jack and the usb port.
The battery connector is at the back anyway, so once you pop off the back, you have access to any parts you need.

1. I did not compare, but opening the front of 8.4 was quite easy and there was minimal risk to break the latches.
2. There's no need to resolder battery just for to get rid of bootlooping. Use power and volume keys to enter recovery or download mode and do a wipe or reflash it.
3. There's usually no need to open device to decide if the battery needs replacement. What do you expect to find there to make the decision?

I just did this today for my tab pro 8.4 (was not charging and got random bootloops). I followed the vid the link below (I got it from another thread on here but I am afraid I can't find it right now)
https://youtu.be/lEVFYQksmxM
Was very easy to do if a little nerve wracking taking it apart ... I just took out the battery and put it back in and it seems to have sorted the charging issue ... Yet to see if it solved the random bootloops, only time will tell ...

[GUIDE] Poco m3 Deadboot TEMPORARY Fix

1. Open phone (watch disassembly vids online)
2. Unscrew top panel screws (except mi warranty sticker one, if you want to keep warranty)
3. Disconnect battery connector
4. Wait 20 secs
5. Keep power button pressed for 1 minute
6. Wait for 1 minute
7. Keep power button pressed and connect battery connector, then release power button after like 2-3 secs
8. Phone should be starting up (connect charger as battery may be low)
DO NOT EVER REBOOT OR SHUTDOWN THE PHONE OR YOU WILL GET THIS ISSUE!!
Note: There is a more permanent fix where you desolder some metal lids which cover the charging/logic ICs, but this guide is for those of us who can't/ can't afford to get that done.

(i made this account just for this)
thank you soo much , this worked multiple times for me , however would you mind telling me the steps for the "more permanent fix" , i have a friend at a repair center and if u tell me the steps i may be able to fix it

i never reeboted the phone again (but when i go out on a hot day with my phone in my pocket , when i reach home it will be off , so i have to do this temporary fix again and again )

HI @zeon_ , the more permanent fix was something I saw in some yt vids online, you could probably find it easily there, I'll also link some at the end of this reply.
I wanted to mention that the fix I mentioned in my post worked for me about 3-4 times before my phone shut off and wouldnt turn on even with this fix, I ended up having to get it repaired, but it wasn't very expensive and it works perfectly fine now.
Just wanted to give you a heads up because this fix didn't work forever for me as I'd hoped it would.
I'm sure that if you have a friend at a repair centre he would be able to figure out what to do, but here are some videos anyways. Most of them target a small metal lid on the bottom left of the motherboard, some say to remove it completely while others say to only remove the two larger caps under it, then reinstall it. They all claim that the metal lid is somehow shorting with the power circuitry underneath, resulting in the deadboot issue. Some also recommened replacing the power ic which I believe is in the larger shielding with the hole in the top to its right (seen in 3rd video). You might also be able to find longer length videos online.
Again, I don't know how reliable these are, proceed at your own risk. I would recommend just handing your phone over to a recommended repairer in your area after backing up and removing your data from your phone.
