Hi sorry I am a n00b in all this lol

I checked and took pics. This is a V5 like you said ... It is the one that has the problem

I live in Venezuela and unfortunately here you can't take your phone to just any technician because they change the parts and make up stories to charge you way more of what it really costs to fix a problem or hey simply keep the good parts

And tell you the phone has no fix

I attached two pics. One has what I think is the shield and the other shows the V5 number. I wanted to ask you ifnthemshield is the small one that shows there. Because the pics some people have show seem to be the same. I got still to find someone that I can ask to remove the shield

Thanks for all the help!
[POCO M3 Questions & Answers] MrHottabych:
remove in any available way
[POCO M3 Questions & Answers] Sus_i:
It's the small shield at the corner, like @MrHottabych showed in the picture...

The best is if you find someone arround you with a hotair soldering station, but if you cover all parts near the shield, a heat-gun will work too. Important is that you remove the shield carefully, without a damage of the inner parts.

[POCO M3 Questions & Answers] newcalf:
i have the same problem but since i found a youtube video of reheating the charging IC though it fix the issue but second time restart my phone i came back again (dead) and i had to do the same process, dismantling the cp then reheat, then it fixed, now im afraid to restart my phone again.

Question 1: why the cp met this issue?

2: is there any connection about the latest update?

3: is it a bug or stgh?

pls. help me explain why it came to this issue its quite annoying for the cp?

ur reply is higly appreciated... thanks
[POCO M3 Questions & Answers] Sus_i:
Heating or cooling or battery draining isn't a fix at all, but it may help to boot the phone.

It's just a hardware issue, nothing to do with updates or OS versions.

This is the real fix:

@sarabbafrani Hello I contacted you on whatsapp I think mine is in Edl
[POCO M3 Questions & Answers] Pasarireng:
(Sorry to be a little bit out of topic here)

Two things are certain;

*that this seems to be happened to so many, if not all M3 phones around the world. Terrifying. How could Poco/Xiaomi sell something this bad?

**that I will cancel to buy this phone. (I was just going to buy this for one of my family member. I think, I'd better not). It's sad, because, on paper it supposed to be a good spec phone for the (low) price.. sad.. Again,.. how could Xiaomi/Poco let bad product like this out and sell it?.. Sad
[POCO M3 Questions & Answers] Sus_i:
Thats why I think that the awesome fix from @sarabbafrani is a story for the xda frontpage :)

Who knows, they have maybe already fixed this fault in production ;)

and if not, the fix is public known and easy to do :p
[POCO M3 Questions & Answers] Pasarireng:
The fix is not easy for me or for many people I know, I'm sure.

(of course you're entitled to your opinion, it may be easy for you, but not for me/many people I know,.. beside, I and many people don't buy a new phone to be fixed or to have any very probability to fix it soon, like the case with M3 as we can read here or on many other place in internet).
[POCO M3 Questions & Answers] Sus_i:
Yes, you are right... but you got me a bit wrong.

What I mean is that some phones need a special repair, like reballing chips, replaceing parts or something challenging like that... and the fix for the M3 isn't something special, it's very easy compared to other phones faults.

Of course you are right, dissasambly an almost new phone and rip shields of the board is awfull, therfore I would also buy an other phone if I were you :)
[POCO M3 Questions & Answers] sarabbafrani:
I use poco m3 as my 2nd phone

I am mobile repair technician for 2nd job

I think poco m3 has good quality in all parts and no other problems (as i worked on it in 6 month and fix above 500 poco m3)

in comparison of other phones in this price range this phone problem solved

Who knows if you buy other phones, it will be ok?

For example: I saw boot loop on redmi note series and samsung A series because of camera fail or lcd fail... that we will change this parts to boot up phone

Finally that was my advice about this phone.

Do your best
[POCO M3 Questions & Answers] sarabbafrani:
why i cant delete my post :)
[POCO M3 Questions & Answers] Pasarireng:
All of the new phones I ever bought since many many years ago, there are not one failed misearbly like the M3's problem I read here and everywhere...

And, I'm not a researcher with accurate data etc nor I feel it is necessary for me to do, but I think, mostly, most of the time, new phone should be NOT having this problem like this M3 problem.

Come on, I respect your opinion and I understand your point about no matter what phone we buy, there will always be probability of error etc, but.. well..its useless for you to defense the fact that Xiaomi/Poco did mistake in this product. Admit it, many if not most if not all, M3 and Redmi 9T too, has very bad problem as we can read clearly in this very thread and also in many other websites forums etc on the internet.

And it made me sad because I have to cancel to buy it because of that, although actually this phone is very good in spec on the paper for the price, which is low enough.

[POCO M3 Questions & Answers] yeisson406:
@tatitar

If I did it yesterday and it works, I was also afraid like you or as many of leaving the cell phone useless (I preferred never to turn it off or restart it so that it would not stay dead), simply disarm it and follow the video tutorial in this forum, I confirm if it works !

Note: the only thing I noticed is that when you press the power button it takes a little longer to vibrate and turn on between 4 and 5 seconds, otherwise everything works: the cameras, the sound, the wifi, the bluetooth, the recovery, the fastboot, reboot and shutdown

Hello.

I have the same problem.

The first time it happened to me, I waited for the battery to run down. Then I put the charger on it, the charging symbol appeared, I charged it for 5 minutes, pressed the power button and it turned on.

Now, it's happened again. But, I can't get it to turn back on. I waited for it to discharge. I put the charger on and the charging symbol appeared. I charged it for a few minutes, but when I tried to turn it on, it wouldn't turn on. I let it discharge again and the same thing happened. That is, the charging symbol appears, I charge it for a while but then it won't turn on.

Before opening the terminal, could you try something else? It's strange that the charging symbol appears and the phone doesn't switch on.

Sorry for my English, I'm using an online translator.

[POCO M3 Questions & Answers] Dr4c0_:
I have a question for @sarabbafrani or anyone who knows the reason. Does anyone know why it works by removing the shield? I ask it because I would like to relocate it if possible.
[POCO M3 Questions & Answers] Sus_i:
From my understanding... there is a big capacitor under the shield, which contacts the shield in some circumstances (Gap to small or no gap in between at all) and this results in a more or less shorting... almost the same like a variable resistor between a power line (capacitor) and ground (shield). I'm sure @sarabbafrani can tell you more details :) His solution is either to remove the shield completely, or to remove the shield / isolate the capacitor / solder the shield back on.

Btw, I removed it completely and his fix worked awesome for me :)
[POCO M3 Questions & Answers] OKatime:
Best regards.

Due to misinformation, I installed the eng ROM and I don't have the bootloader unlocked. There is some method to restore to any stock rom. I am in EDL mode, And it managed to get to the fastboot screen despite being locked by EDL mode. In case a stock rom cannot be installed, it is possible to install the Google apps (YouTube, Gmail)

[POCO M3 Questions & Answers] CLS_phone:
The phone drained out after 2 or 3 days, and it reacted to long-press on power button -- vibrated a little, then an empty battery icon showed up. I plugged it to the charger, then it came back -- showing Redmi, MIUI, home screen.

When it's charged to 7%, I thought, damn, can it restart? Then I tried. It died again, couldn't be waked up.

About an hour later, it drained out. And the whole thing started over again. Now it's charged to 45%. I guess it's supposed to be powered on all time from now on.

My POCO M3 has turned off two times before. First time I did battery disconnect reconnect and phone restarted.

Second time it turned off after 1.5 months again and I have to get it fixed from a technician by soldering method.

Now for the 3rd time it started to behave abnormally

- many apps started to stop working, lag in performance,

- delay in whatsapp message deliveries,

-WhatsApp pictures not opening or opening with blurry pictures,

-incoming calls not showing on screen at all.

Then it hanged with incoming calls, and finally turned off and didn't turn on.

What should I do now?

[POCO M3 Questions & Answers] sarabbafrani:

[POCO M3 Questions & Answers] Sus_i:
Hi @sarabbafrani

I guess I have got a bad wifi antenna connection between the spring connectors on the Poco M3 and the golden metal-foil pads from the backcover. Wlan is really bad, until I do a hard press with the thumb on the cover next to the camera... then the wifi strength gets normal for a few hours... It gets also back to normal if I remove the cover and assemble it back.

A close look to this antenna metal-foil pads in the backcover expose some markings from the spring connector, I guess thats the culprit. Thought about to apply a small amount of solder, but I feel that will mess it up completely.

Do you have an advice on how to fix this?

Best regards :)
[POCO M3 Questions & Answers] Loop-x:
i don't know if the method i tried will work for everyone but if still want to try then you will have to be patient like i did because mine happened to me about 1 day 9 hrs ago as of the time i posted this.

i won,t advice u guys opening ur phone to try to fix the problem if u aren,t a technician.

and if ur sure the problem isnt from hardware issue and it happened like mine when i tried to restart my phone and didnt come on. i wont advice u to quickly give a technician to fix the problem or u trying to open the fixing it immediately. u shld try this becos doing anything else. if it doesnt work u are free to do anything u want.

ok now these are the steps did:

i tried the steps people posted in this forum the 1st and 2nd time it happened to me and it work after trying it over 7hrs and 3 hrs respectively.

the 3rd time it happened to me none of these steps worked. so as for this step u will have to drain ur battery completely, if u arent patient and u have other phones or a laptop to be using for the main time. it will take abt 5-10 days for the battery to drain completely if fully charged according to someone in this forum when doing nothing. using my method it might take u approximately 1day 9hrs to 2 days to drain it completely, if fully charged.

so how do to drain it faster is by holding the power button as long as u can. u can take breaks but continue doing it, what is happenig is that the phone will be keep up on turning off and on with and u wont be seeing it happening but if u connect it to a laptop u will notice it and if u put ur face on the screen after a long time pressing the power button u will notice that the screen is hot , eventually when the battery is completely drained then u will notice that the phone will then vibrate and show the charge icon, meaning that the battery is completely drained. then what u shld do next is to charge it, then switch on ur phone and that is it.

lastly me advice to u all, if u want to restart ur poco m3 next time instead of using restart just use the force reboot method by holding ur power button, do not leave the button, till the phone switches off and turn on.

i hope this method works for u all. if it didnt work then u are free to take it to the technician for repair.
[POCO M3 Questions & Answers] AlphaBravo:
This method has already been tested, advised and being followed.

One fellow here advised to put an earbud over the power button and a tight rubber band around phone over that earbud to continously press the power button to drain the battery faster. I have done this thing successfully.
[POCO M3 Questions & Answers] rotoko:
If I can advise you,

hardware error is unlikely, mostly software

we need to get to EDL software so we can revive the smartphone, but we need Poco M3 Citrus Eng Firmware (you can't fix it without it), which we install via Miflash, we install recovery via fastboot and flash rom.

Like is that.
[POCO M3 Questions & Answers] digimoni:
- CONFIRMED! -

I was little suspicious about @sarabbafrani advice, but it actually worked!

My Poco M3 went nuts after shutting down the alarm clock, only few symbols visible on the screen but otherwise totally unusable. I was able to power up the screen or shut it down but couldn't access the phone software. Only option was to reboot or shutdown with power button.

After reboot, the phone went totally dead. Couldn't boot up, not with long press power or power + volume up (or down). Plugging in the charger didn't do anything, no vibrations, nothing.

I did that phone disassembly, remove battery connector, push power button and plug battery again = normal boot. After this happened about 3 times within a month, I decided to try sarabbafrani solution.

Tear down the phone, remove plastic main board cover, took all 3 cameras away, disconnected antenna and took the main board away.

I had only hot air gun and decided to cover other parts with aluminium foil. First, I tried speed 1, but no success. Then full power, 5-10 sec blowing 10cm distance, firm grip with pliers and heat shield was out. It almost fell down. Do not use excessive force!

After cooling down I put motherboard back in and tried that same procedure with power button + battery cable in = nothing :( I thought I fried the whole thing. But when I plugged in the charger it showed the Poco logo and battery level - that's new. Decided to put everything back together.

It required a long press for power button and the phone started normally! I even did a software restart and it started normally. Charging works also normally.

I've been using it now only for few hours but hopefully the fix is permanent.
[POCO M3 Questions & Answers] Sus_i:
Fix is permanent, did the same months ago and it works fine :)

Only the M3 wifi strength is still very annoying, I guess it's because the pads in the backcover are to soft, I see some deep marks on it from the spring antenna connectors, which (maybe?) leads in a bad contact. I saw a post from someone, who was adding a small amount of solder and claiming that will fix it, but Idk, haven't tried it for now.
[Android Auto General] landous:
Take a look at the picture. It's almost impossible to read the clock on the top right corner. It would make sense to dedicate a larger corner of the screen just to display the time and maybe the weather in an easier-to-read font. It should be optional so you can turn it off if your car's head unit displays the time elsewhere and you don't need two clocks.View attachment 5328067
[Connected Car] ForeverRogue:
Apologies in advance - I could not find my specific issue in the forums using any related keywords. Sorry if it exists somewhere.

Phone is a Samsung S21 Ultra running Android 11. Pretty sure it's not a phone issue as I've had this issue wth other phones but can't remember how I fixed it. I am not running Google Android Auto app. My phone connects to my car through bluetooth and phone functions work perfectly - I can make and receive calls through voice command and my contact list is available. Two issues I'm having concern sound from the phone speakers. Sometimes I have to use Google maps through my phone because the navigation system in my car isn't updated. Google maps works except there is no voice guidance from the phone speaker as normal (voice guidance works when not connected to the car). There is also no voice guidance from the app through my car speakers. UPDATE: I just discovered a setting in Google maps to "Play voice over Bluetooth" so maybe I'll try turning that on and see if that works. My second issue is a sound issue as well, but through YouTube. Sometimes I'm a passenger in the car with my phone connected through BlueTooth to make and receive calls, but if i try to play a YouTube video there is no sound through my phone (or my car) speakers. If I could get it to play through my car that would be optimal, however I'd be fine with just having YouTube through my phone like it used to. I'm pretty sure last time this happened it was an app, like Android Auto, or Google Auto and when disabled things went back to normal (sound playing through the phone) and that's why I haven't connected Google Auto so far. It could be a BlueTooth setting but I just don't know. Any ideas or suggestions appreciated!!
