[Q] After booting in to android my phone just vibrats and shuts off?

I dont understand i have tried everything! I must be missing something
I have booted before with no problems aside from the robo voice
I come home in hopes to fix it and now no matter what build i use no matter what zimage i use the phone boots like normal in to Android and then just shuts down.... What am i missing here?

Spent all Morning Flashing rom and radio combos and still the same thing, Reformatted my sd card Nothing.
NO HELP?

this happened to me when i started using my extanded battery, no matter what i did it boots vibrates then shuts, im back to my normal battery all the builds work now, i figured out that the extended battery might need a driver or something.

here the same! with original battery is working
With extanded battery is shutting down! in one line by booting with haret
Chragin off (temp overheat)
battery working with
desirebuild_v5
battery dosent work with
mattcfroyorc1.4
mattcfroyorc1.3a

Wow never even thought about changing back to a stock battery. Or even mentioning that i again

This happened to me when I had a multi-boot program installed on the winmo side. Uninstalled it- booted just fine.

there have been a couple of threads with the same issue.. the devs have been asked about it.. nothing heard back as yet.. but it definitely it is an extended battery that is causing it

Yes the extended battery is it. I read it somewhere in the forums that it is not supported yet as there are no drivers and due to which while booting haret reads the battery temp to be 90 while it actually being ~30 and hence cant boot.
Replace it with stock and you are good to go

Mine is still the stock battery and still does the same thing for all versions of ROM and android too..

Are you using the stock HTC battery cuz im sure if the exteneded one dont work neither will cheap replacment batteries
Works great with my stock battery;
Never thought in a million years to try without extended battery lol
Only thing now i have to do is get over the robo voice.

Any one help me on this issue?

thinks its charging....

so i've noticed multiple times today (just got it yesterday, rooted) that the charging indicator flashes on and off. this keeps bringing it out of standby. although sometimes the screen turns on without it saying charging but that seems to be a known issue.
but whats up with the charging flashing

full reset and its still doing it
actually i think it has to do something with rooting
i used this http://androidflip.com/how-to-root-acer-iconia-a500-with-stock-honeycomb-3-1/
but i unrooted and uninstalled and its not doing it now....
any other root method for 3.1?

Strange
Never had this issue on my a500 - but have the exact same issue on my Samsung Intercept with a slightly damaged charging port - after unplugging the system will still show as charging and offer to mount as an external storage device - even though it's not plugged into anything.
Had the random screen on when I was still on a 3.0 based rom - have you registered your tablet with Acer and upgraded ota to 3.1? Can also manually flash 3.1 update.
best of luck!

i just updated my last post,
but yeah im on the latest ota 3.1 in the US and registered

(Edit: the method you linked to looks like the same method described here at XDA. May not solve your problem)

well cancel my happiness. did a reboot and now it fully thinks its charging. no flickering.
even plugged it in and unplugged and still says charging.
this time i plugged it in and rebooted. at least the notification went away
edit: and its back.

really strange....
May want to just return it and snag a new one if that is easy/possible.
After your full reset did you do any Modding/install any apps? May be possible something you are running is causing the issue, but I am really stumped on this one.
Could always get cwm running and reset the battery cache, but I am pretty doubtful that is gonna do anything.

same problem for me here.though I did not root my device yet.it shows charging with no charger plugged in.also recognized that my battery indicator sometimes remains on a certain percentage and hangs.after a restart it shows the actual battery level.I am on stock rom 3.0.1...maybe I send it back tomorrow.because this is really enoying...

yup. mine just started doing the hanging at one percentage til reboot

don´t know if it´s software or even hardware related

the fact that we have identical problems makes me think software

[Q] A very strange issue with my battery

Hi.
I have been having very strange issues with my battery, and I hope that there are some people here who know about the hardware more than I do and might be able to help me.
First of all, the battery indicator is unstable, it can show me 49% of battery and suddenly tell me there is only 10% left. I am attaching a screenshot of my battery stats where those spikes are visible.
Or worse, the battery indicator might suddenly jump to 0% and make the phone turn off, then when I turn it on it shows that it has at least 25% left.
Second problem, I very often can't charge the phone. I connect the charger, and the notification LED doesn't light yellow, instead, the whole battery menu just disappears from the settings so I can't access it... And after a few hours it might begin actually charging, then the menu is visible.
Battery temp always shows -30 degrees celsius, or some similarly impossible temperature.
After trying to switch to a different kernel (from unleashed to hells core) and to a different rom (from purity to android L and liquidsmooth) I decided this is an hardware problem and bought a new (hopefully original) battery on ebay.
I installed the new battery. Now it does work a little bit better, but still, the problems persist.
Is there anything I can do, before buying a new phone?
It doesn't have warranty anymore, it's one and a half years old.
Thanks

Definitely battery failure. Replace the battery or buy a new phone

This is most definitely due to a faulty battery, so time to get a new phone. At least Shamu's release is right around the corner.

Hi
Thanks for your help.
I did replace the battery a few days ago, and the problem still persists. Which makes me think it's something else.

I'd try comletly stock rom, and see if the issue persists.

Yup, stock ROM always first step, then replace battery. If it still persists, than it is most likely some other hardware issue that might not be worth it to replace.

Exactly same situation with my Nexus 4. Battery being replaced and it's not better. Just ordered a Moto X 2014 and waiting for it.

I tried the stock ROM. And it didn't solve the problem. Is there anything else I can check about the hardware before replacing the whole phone?

Have you just flashed a stock rom, or completley restored the phone to factory settings using google factory images?

Hmm unfortunately this leaves me without any ideas. May ask how old is your phone and did you drop it previously?

It's one and a half years old, and well, I did drop it a lot.However, I always used a good case (ringke fusion) and I don't recall any recent drops prior to the time the problems started.

Anyone else experiencing touchscreen issues while charging?

The strangest thing just happened to me. While I was charging my OPT it failed to register my fingerprint. Upon asking me for my pin, the touchscreen acted very erratic, and after 5 seconds stopped working completely. The moment I disconnect the charge cable everything works fine!
If my calc or any other app is open it also registers a lot of touches without touching the screen. It's nothing you can replicate. Kinda spooky actually lol.
I've tried a couple of things already, rebooted, killed most apps, checked the charge cable (original) and port but to no avail.
I have the US version and am on the latest stock ota, but rooted. I'm about to do a restore and after that clean install if necessary. I just wanna check if anyone experienced this before.
I will lost back if I get to the bottom of this. Hopefully it's not the hardware.

Does not happen so often on my OP2 but it happened a lot on my Nexus 4. This is a known issue with many devices but nothing you should worry about.

Thats not great news burnoutslo! It's pretty annoying that you can't use your phone while charging. I've noticed that once it reaches 100% everything's ok again so it definitely seems software related, probably android if other devices have the same problems. I will do a nand restore back to the previous oxygen version over the weekend. Hopefully it solves my problems.

I observed same thing yesterday,
The whole scenario was-
Yesterday when my battery gone below 15% i ran for the charger and plugged in and after that i started using phone and i noticed that my touchscreen becomes less responsive.
Difficulty in swiping between home screen, opening of apps during swiping.
So the solution i found that if i stand on the ground barefooted then only i am having this problem, when i put slippers on then its perfectly fine.
So may be it is some kind of grounding issue.

same here; issues sometimes when charging; I didn't see the differences between sleeper and barefoot but I also think it's a ground problem...

I had once this issue on cm12.1 oneplus 2 . What I did to solve this problem successfully.
1. I removed case from my phone . This causes grounding issues sometimes.
2. Reflashed OxygenOS.
3. Then I flashed cm on top of it. Wiped data, cache, dalvik only. didn't wiped system partition.
4. That's it. I'm. I'm typing right now while charging. Totally perfect.

I noticed it more with my cheaper USB C cables.
I bought a half dozen and some are better than others.
the boxed cable that was stock is the best by far.

Yesterday i aux in my phone to a audio player and observed the same problem again with touchscreen. Feeling very annoyed because of this and other bugs.

My phone used to lock up completely for up to 30 seconds after plugging in the charger. After move to cyanogenmod 13 this does not happen anymore, so obviously a bug in OxygenOS.

Hmm, this is generally not a problem with your phone or your software, but relates to the power supply. Noise in the power or grounding issues specifically cause the 'ghost touches' and erratic behaviour you describe. If you are lucky, your charger and cable are also fine and the issue is with the power socket, in which case you need an electrician to come and take a look. If its the charger/cable, then simply get a new one and you are good to go.
To figure out where the issue is, start by using the same charger + cable in a different location (completely different physical location). If the problem persists, then try changing the cable in that same location. If it still persists, try a different charger.
If the problem is NOT there at the alternate location, then chances are its your wiring and you need an electrician to sort this out for you.

Fingerprint (again)

Hi,
I know this has been discussed many times, but I have something more to share regarding this, and maybe it can help anyone find a solution.
My X820 arrived last Friday, bought from Geekbuying. It had Indian 19s ROM, although it might be slightly modified by the shop.
Fingerprint was working well, but I wanted a better and more optimized ROM, so I flashed TWRP and got Small EUI. The worst thing is that I forgot one important step (yes, backup) and flashed the ROM right away.
Fingerprint kept working, but got worse. On Indian 19s, it unlocked the screen or apps very quickly, but on Small EUI it took it 1 or 2 seconds, so on Sunday morning I tried the calibration option under settings. That's the moment the fingerprint scanner stopped working. I spent some time on Sunday, and most of Monday trying different ROMS, but nothing worked. The sensor would not react at all, and would not let me add fingers.
Yesterday, I found a thread, on a OnePlus 2 forum, where people described a similar issue on that phone, and the way they got the sensor to work again: they drained the battery down to 0%, to the point when the phone would shut down by itself. Then they charged the phone again, and the sensor came back to life.
I tried that (I'm now on Cuoco92's 93c ROM), and after turning the phone on again, the sensor seemed to keep failing, but there was a difference. Before that, it wouldn't react at all, but this time, a message instructed me to keep my finger on the sensor for a longer time and to try again. This message was not appearing before.
I left the phone alone for the night, as I use it as an alarm clock, and in the morning I tried again, and it worked. I was able to register fingers and the sensor began working as usual, and unlocked the screen almost instantly.
But now,. two hours later, it is dead again. I've noticed it doesn't unlock the screen. I've just tried to remove the fingers I had registered earlier and see if I can add them again, but it doesn't work. This time, there's no message that instructs me to keep my finger on the sensor for a longer time, or to try again.
Well, I definitely haven't solved the issue, but I may have found something. Maybe others with dead sensors can try this solution and report back.
To drain the battery, I used this app: Your Battery Drainer
P.S.: BTW, I decided to try draining the battery because I remembered that when first I got the phone, the battery was empty. I almost freaked out when I tried to turn it on for the first time, as it wouldn't turn on, but it turned out to be that the battery was empty. After I left the phone charging for a while, it turned on normally.

I also just got my phone today 6gb RAM, 64gb UFS2.0.
Fingerprint very fast with 19s ROM.
I think I will stick with this ROM forever.

You should, that was my mistake (I think) besides the LeEco software, and maybe fp hardware, not being too good. I just flashed the stock Indian 19s ROM again and the sensor is not working. I'm now downloading the Chinese 16s version, which others reported helped them revive their sensors. If the Chinese ROM doesn't work, I'll flash the Indian ROM again and try draining the battery in the evening, as I did yesterday.

Good investigative work. I wish you good luck and will be reading this thread until you get it working.
I am quite happy to get this for USD186 for current x820 version even though without headphone.

Will wait for your result . 19s is actually badly optimized. I got 99k in Antutu.

I try every method with roms with apps but fingerprint newer works.
today i read this thread, i try now to drain battery with this app and i cant believe fingerprint start work.
But how long fingerprint will work.

Is there a possibility quick charge 3.0 heat kill the fingerprint sensor? Did you enable quick charge in the menu? Mine one still disabled and I am now worry to turn it on.

That might be it. Today my sensor is not working, after draining the battery, but last night, when I charged the phone again, I did it with the fast charger. When I have the time, I'll try again with a pc or just disabling fast charging. Maybe you have a point there. Nice one.

You mean the modem files, don't you? That was also one of my next steps, but first I'll try draining the battery again and not using quick charge afterwards. When I first got the phone with an empty battery, fast charging was not enabled, so it took the phone ages to charge, but the fp sensor worked. I think we may be close to a solution for everyone, and something LeEco should know. Maybe they can implement an slower fast charge which doesn't interfere with the fp sensor.
Anyway, fp sensor was not my main reason for purchasing this phone, so it's not that high on my priority list.

As another user suggested, disable fast charging, if you have it enabled, and see if fp sensor keeps working afterwards. It's good to know this method worked for you, too

Well, after flashing the Indian 19s ROM and draining the battery, nothing changed, but it could still have something to do with fast charging. Although I had it disabled, when I plugged the phone in, using LeEco's original charger, it charged the phone fast, rather than slow, so I think that maybe it didn't work because of that. I'll repeat the process again, this time using an old regular slow charger.
Did anyone else tried? Did you succeed?

I scared that quick charge heat already kill the finger print. I mean hardware is dead.
But I still support support experiment to fix the fingerprint.

I think the FP problem has to do with HEAT. The FP failed to work when I was on holiday in Florida a few weeks ago. When I returned to the cool Toronto ,Canada, it is back to normal - works most of the time.

Fast charge generates a lot of heat, that's why it's our main suspect right now

Did you flash 23s modem? not the rom, only the modem and after the update of modem clean install of the rom ?

I have tried.. draining all battery from 25% to 0% and smartphone Switch off and after i charged almost 50% without fast charge and tourn on but unfortunatly fp still dont work

Listen guys, I hate to burst your bubble, but I have to... For starters, there are MANY people in the forums flashing all sorts of ROMs and different things, and their fingerprint readers still work. I can say the same thing for Quick Charge 3.0, everybody uses it, so I highly doubt that either of these things are causing the hardware failure.
Also, remember that OnePlus uses Dash charge and all heat is relegated to the charger and not smartphone.
I own two X829's that I bought from Banggood for $196 each a few months ago, and the fingerprint readers still work after countless flashing and charging, and believe me the phone has gotten incredibly hot at times too.
Early on though, I thought that my fingerprint reader had died because it stopped working on when I moved to the Nougat ROMs and later I found out that I needed a more recent modem for the fingerprint reader to work (23S or 419D), but what I have done in a panic was contact Banggood and I told them that my fingerprint reader had died on both my phones. I told them that I had already troubleshooted and consulted the forums. I told them that it was a common defect. I made a YouTube video for them showing the problem. They told me that I could return it to them to China and that they would refund me, but I told them that it cost too much to ship to China and that the last time I returned something to them it got lost in the mail. They then said that I could take the phones to a local repair shop and that they would refund me the cost of the repair, they said that the most they could refund me was $116, so I made a fake invoice for $116 and send it to them because I had bought two fingerprint readers from AliExpress for $7 each and wanted to repair them myself.
In the end I never needed the fingerprint readers because I was wrong and sold them on eBay, and Banggood refunded me the $116 for the so called repair, so in the end I only paid $82 for my Le Max 2. Hope this helps!
