charging problems on xiaomi a2 - Xiaomi Mi A2 / 6X Questions & Answers

Hi, my name is Pablo, I am new and this is my first post.
(I don't have much English, so I'm using the google translator)
I have a problem with charging the xiaomi a2. I bought the cell phone with Android 8.1, what caught my attention is that in the notification bar, the option always came out as if the USB cable was connected and when I connected the charger, I had to lower the bar, open the USB options and select to load (did not start loading without choosing the option)
The biggest problem started when I updated the android and this option in the notification bar did not appear anymore, I connected the charger and did not take it. The only way I would take it was by restarting the cell phone and I knew it was charging (and sometimes it was very slow).
- It is not a problem with the charger because I have already tried several
- It is not a problem with the usb cable because I have also changed it
- It is not a problem with the cell phone connector because in Android 8.1 it always works or (if I restart it in another rom it always takes it)
I have tried changing rom (stock, google experience, havoc, miui) and none was solved (I had to restart the cell phone to start loading)
Please help me to fix it, in android 8.1 the proximity sensor malfunctions and I can't take it anymore
Thank you in advance, I hope I have published in the right place

USB port problem doesn't let the phone sleep

Hey guys.
I have the famous USB port problem, in which, even after disconnecting the charger, the phone shows charging, and dis-charging in an infinite loop. So due to this, the screen doesn't switch off because, due to this problem, the phone thinks that the charger is being connected and removed, connected removed .. so on. and hence, the phone sometimes acts like a heater, and also oozes battery. Just like is in the starting of this video here: http://www.youtube.com/watch?v=duzTDyt_bN4
As a solution to this problem, I switched to MIUI (the Venegence MIUI 5), which recognized the small intervals of charging and disconnecting as just charging, and hence didn't keep the screen on. But there was a problem. the MIUI got bloated, (and also i got pretty bored using it). so i had to swith to official JB again. And again the same problem continued.
If MIUI doesn't recognize the small connect and disconnect, why does the TW JB? and is there any tweak that can be applied on the stock JB rom, to not light up the screen when charger is connected? i think that the phone keeps the screen on because it thinks that it has been connected -> 'turn screen' on and disconnected -> 'turn screen on' and connected -> 'turn screen on' again. If it is said to the phone, don't turn on the screen when connected or disconnected, then i think the problem is solved. then there is no other problem on the phone like the others have. - pc not recognizing, connect disconnect sound or anything. everything else concerning the USB port is working fantastic. just this screen on thing.

It's Note's weak spot. I had the same problem and it's obviously not rom related. I fixed it by replacing the usb port. It's a couple of bucks on ebay and there are YouTube guides on how to do it.

there is xposed module which includes the option for wake up on plug. Gravity box has it, there should be another module too with that feature. Also in Omnirom it is already included in settings>display>wakeup on plug if you uncheck it, it wont wake up on plug and unplug.

Can you guide me how to do this? any links or stuff? i found this on xda, but i doubt it works for note with stock JB. http://forum.xda-developers.com/showthread.php?t=2316070
I am thinking of installing the omnirom. the install instruction says:
- Make sure you're running a proper working ClockworkMod-Recovery - WITH SELINUX SUPPORT!

Does the HelloWorld kernel's CWM support Selinux? if not, where can i find and flash one?

You dont need nothing of these things, you only need your phone rooted and ICS or + (even kitkat supports Xposed modules).

But the http://forum.xda-developers.com/showthread.php?t=2316070 says (and that too in red) that it is not for the TW roms. Can you confirm? Can you provide with some instructions or link which i should follow for installing Xposed module on the stock TW JB roms? I currently have TW JB + HelloWorld kernel.

I first installed the gravity box, set the don't wake on plug, rebooted, but the screen still turns on. removed gravity box, installed the xposed additions, set the don't wake on plug, rebooted. the screen still turns on, but it vibrates when the display shows charging and not charging. I suppose the Samsung Framework doesn't support don't wake on plug unplug.
can anyone tell me which kernel is required as prerequisite for the omnirom? I am currently on the helloworld kernel. does this kernels CWM has the selinux support?

I have found 2 revisions for the same part. how to know which revision fits inside mine? the date on version 1.0 is 08/2011. i bought my phone in 06/2011. so i think this must not be the rev i need. maybe the 0.0. but does it matter? is it important to know which rev is inside mine? or is the 1.0 backwards compatible, in case i have the 0.0?

I didn't find any difference while searching for mine. Just look for n7000 usb charging port replacement.
http://m.ebay.co.uk/sch/i.html?kw=G...d=&sqp=&_trksid=p2056088.m2428.l1312.TR1.TRC0
The second one comes with screwdrivers.
EDIT
Just checked my old usb charging port that I still keep after it has been replaced and it has the following stamp with golden letters:
N7000/I9220_SUB_REV1.0 2011.08.30
I bought my phone May 2012. Not sure if it matters though...
Hope this could be of some help.

Xiaomi redmi 4 not connect to pc

Hello,
First of all send a greeting to everyone since I am new to the forum.
I explain the problem to see if someone can help me.
I have a xiaomi redmi 4 ( sorry if my phone is not the 4a, but I cant find that model in the menu) with "fake" rom from the Chinese store. I know because the version ends in 0.0.
The problem is that when you connect the phone to the PC it does not do anything, it just charge (previously it worked well and the pc recognized it, also going out in the curtain the options to select load, mtp, etc.
I have tried several things and nothing works.
Probe activating usb debuging, with the app usb settings (which seems to open those options but quickly closes and the screen goes blank) and more different things but nothing worked, still only charging.
In the device manager it does not appear, neither as a connected device or as a connected device but without the drivers (I have the drivers well because before it worked correctly).
It all started when the battery stopped charging correctly, the battery charged very slowly. With the ampere app you can see that the charhe was very weak, no more than 100mah. Clean the usb port, probe with other cables and chargers, other pc but nothing to charge faster as usual.
Then I decided to restore the phone to factory but continued the same, charging very slow.
Later I decided to put a global rom using miflash with mode edl ( the bootloader is closed), but the phone never entered in that mode. Use the technique of power + vol + and vol- and I got it right. In the device manager I recognized it correctly (with the correct name that usually say in the guides for this type of operations), but miflash told me it was not connected.
Also use the adb commands (also recognized the mobile without problems, leaving the id of the device, but when using the abd reboot command, but the phone do not entering in edl mode, the phone restarted normarlly, even with some .bat that does the same thing also restarts in normal mode instead of edl.
For all of this operations the pc always detect the phone correctly, only the charge was extremely slow.
My surprise came when a few days ago I tried to remove the fake rom of the Chinese store and put the global, but the pc (mine and others more than probe) did not detect the phone, just charged me.
I think the problem is not physical, because if I plug in a mouse by otg, it works correctly, which makes me think that the data pins are going correctly.
I hope I have given all the detail that is needed in case someone can help me. If not, please tell me what else I can contribute.
Many thanks in advance to those who can help and greetings.
PD: sorry for my english
If in other computers donĀ“t work, probably its the port that is damaged and you should replace it. You can find some in aliexpress..

Usb connected disconnected notifications fix

All
I have the dreaded usb connected usb disconnected notifications on off on off fault on my phone.
I tried to clean the usb = no luck no water or fluff in there
I tried to clear cache on usb settings and rest start - no luck
I tried rice in a bowl - no luck
I tried to factory reset no joy
But what works and saves battery drain is the following
Install the pixel experience custom ROM or and pixel custom ROM, lineage worked for a bit but then I got the notifications again.
The issue is still on the phone when you look at usb setting but your phones battery won't drain and you can turn your phone screen off and it won't turn on again all the time with the notification.
Also if it says usb connected just restart your phone and it goes away.
I thought I would share this if anyone else has had this error and didn't want to upgrade just yet use the above temp fix to buy you some time.
Please see posts on here to install a custom pixel experience ROM for your phone.
Please let me know if this works for you and comments below.
I'm now on android 13 but it worked with 12 as well.
Hope this helps
Hello majordj, you are talking about the pixelblaster rom under android13, it must come from the rom.
As according to some discussions that I saw the S10 will not be updated android 13, if you have installed the romp pixel blaster under android 13 ask whoever develops it if it is compatible with S10 exynos or not.
No I'm taking about I had a issues with my S10+ where it kept says in the notification usb connected then disconnect and the screen wouldn't go off plus a cable wasn't pluged in. I was on the original stock ROM, as a last try to fix it I flashed the pixel experience ROM and it works and you can carry on as before

Moto G4 Play doesn't turn on disconnected from USB, can't boot into recovery bootloop

Today I was remembered of an issue I had already faced with my harpia, it's an weird state of bootloop in which even a full firmware flash won't solve anything.
If your harpia has the following simptoms:
1. Doesn't turn on, but you notice you can access the bootloader when it's connected to a USB cable(charging, with the other end either on a computer or on a socket)(If you only connect and don't press Power + Vol - it goes into bootloop again);
2. Bootloop (when connected) - doesn't even vibrate, only shows the Motorola boot logo for some seconds (sometimes a little bit longer for some reason) but then reloads it and keeps bootlooping;
3. You can access the bootloader (when connected via USB) and flash but it keeps bootlooping;
Then you might have the same issue I had!
One could think the problem is a faulty or old battery, but it's not - SOLUTION: Change the daughterboard.
Yes. Weird, right? I don't really know what it is but some problem with the daughterboard (the little second board that has the USB port, also called 'charging board' I guess(?)) causes harpia to bootloop.
I also noticed that harpia doesn't boot at all without one of those, at least my model (XT1603.)
I'm posting this here because I saw some old posts on lenovo's forums which had the same symptoms as I found in my harpia but didn't get any help from Lenovo, aside from the good old "send it to a repair shop".
Hope it helped!

A few times I made the experience that also the USB cable could be "faulty". You can charge the phone with this cable. But you can't establish a working data connection with this cable. Sometimes it looks like it works, but it doesn't really ... you have weird behaviour. With other phones this same cable works. Or vice-versa.
Therefore it is always a good idea to have many USB cables to switch ;-)
