Emergency Only while Charging - Xiaomi Poco F1 Questions & Answers

Hello everyone... i just bought a second hand poco f1 one week ago and i have problem whenever I'm charging my poco f1, suddenly the signal is going to no service/emergency only even i have a wifi in my home it's still cannot connect to internet and then with 3/5 minutes the phone going to restart it's self when i'm browsing or just leave the phone charging with the network on... but when i'm playing pubg mobile with the phone charging and the network on it's work normal, but when i'm going to browsing again the phone error again, i have change the rom from miui 10.2.3 global stable to 9.3.21 beta but the problem still same...
and today I have go to xiaomi service center in my town they just flashing the rom back to miui 10.2.3 global stable again and I tought the problem is solved when I'm checking again about 10 minutes with no problem, but they use a Xiaomi Mi Smart Power and I assume the output is low ampere, then in my house i use the original power adapter and cable poco f1 but the problem going back again....
did anyone have the same problem? or it just a software problem... should I change my rom into custom rom? or it was a hardware problem?
I hope someone could help me with my problem...
*sorry if my english is bad*

Might be hardware.

Don't ever use the phone like heavy tasking (gaming and stuff) while charging. It can cause thermal throttling on the CPU and the Battery (decreases its life) and it can cause a lot of issues.
Also you mentioned that you bought it second hand.
Did you have the official receipt or official invoice from the seller? If yes, go to a nearest Xiaomi Service Center, explain the problem that it is not software rather than hardware and let them check if there are damages. Might the seller wanted to sell the Pocophone F1 because he/she has issues with that.

Redmi note 2 Microphone bug

Hello. I bought this phone some days ago.. But when i make calls is very frequently that i can't ear anything and the person on the other side can't ear me. Im on last stable from Xiaomi.eu. Any ideas?
Defective microphone. You should apply for a refund. I also had this problem before with another phone, the seller give me full refund when I sent it back.
In my case it was working with recorder but phone calls or Google voice recognition weren't working.

Hey, I'm bringin this topic back to life. I'm also experiencing issues with phone call feature - people on the other side say they can't hear me well and that I sound like I'm standing far away from the phone. Can anyone tell me for sure wether this is a software or hardware issue?

Sometimes I have microphone issues too into calls , but only when I use speaker... Doesn't matter what ROM I use. I guess that's just the cheap quality parts into our device.. ( like soft keys stop working after 1 year )

This is funny! I had exactly same problem.
I was on global beta when it happened. Then I switched to global stable miui and the problem was GONE. Now I'm on Angel and Demons v9 and so far no such problems.
I'm using latest global stable. :/ 8.1.2.0.

Redmi Note 3 Pro call quality issues with one mobile network operator. Wierd signs...

Hello everyone,
Let me begin with saying that i've already contacted MIUI support as well as i've searched other MIUI forums for the solution of my problem, wich is really strange to be honest.
I own an original Redmi Note 3 Pro (previously i owned a Redmi Note 3G). I use the largest mobile network operator in my country and he gives all his customers the ability to use other mobile network operators range/connection in roaming for free whenever we like. It doesn't support 4G from different vendors, so it's 3G max. This is important factor later in the story.
__________________________________________________________________________________________________________________________________________________
The phone was originally shipped with MIUI China Stable ROM wich run fine but as you know it had a lot of crap in it including adds and a lot of wierd chinese apps. But it DIDNT'T cause my any trouble with phonecalls quality.
I used MIflash & download mode to flash the latest MIUI Global Stable ROM, wich in the beginning didnt cause me any problems with phonecall quality.
HOWEVER. After 1 week of using the phone, one of the updates for Global Stable came out. Phone was updated without any problems and it run fine, but i noticed that whenever im talking with someone the quality of the phonecall was lower then ussually.
Then another update came out and it was EVEN WORSE. I thought it's the issue with the ROM itself so i patiently waited to get my permissions for unlocking the device.
I finally got it so i flashed my phone with MIUI China DEV ROM, installed TWRP and installed the latest MIUI available for my country (wich i previously used for over 2 years or RN 3G) wich also includes fixes and optimizations. HOWEVER the problem still occured.
I then started to blame my SIM Card, so i got a new one yesterday, i also did a factory reset just to be sure, DIDN'T HELP.
So to SUM UP:
Issues: Call quality is low in random calls
How does it show: Caller speaks like with a robotic voice, interference, sometimes i don't hear the caller for 2-3 seconds.
ROM STORY:
1. I purchase RN3 Pro. It comes with original china stable ROM. Phonecalls work fine.
2. I install global stable. Phonecalls are fine.
3. I install two updates to global stable - the quality of phonecalls goes down.
4. I unlock bootloader and install custom ROM along with TWRP, same issues.
5. I reflash whole ROM, clean installation, same issues.
6. Yesterday : I get new SIM card, i factory reset my system and get new updates: SAME ISSUES.
Wierd factors:
- sometimes when the problems occurs while on call, i can resolve the issue with just waking up the screen for a couple of seconds..
- problem seems to happen less when WIFI/Data usage are off
- problem seems to happen less when using headphones (Piston V3)
- problem DOESN'T happen AT ALL when i switch to other mobile operator network in roaming! It's only happening in my main mobile operator network! I would use other networks instead of mine but LTE/4G isn't allowed yet while on roaming :/
- this issue happens on both SIM CARD slots, on different SIM CARDS
I tried to reflash China Stable, however it seems that there were too many updates and one of them is causing the problem now on every ROM. There's a few topics on MIUI Official forums about that, there are bug reports about that but i doubt MIUI Devs will notice this.
Does anyone have any idea what could be causing this?
Link to my MIUI topic: http://en.miui.com/thread-267736-1-1.html
Link to random bug report about this from other user: http://en.miui.com/forum.php?mod=viewthread&tid=266620&page=1#pid4845168
Kind regards,
Beliares
hey what happened to your device?
I think my redmi note 3 pro has the same issue, call quality seems to go down where I would lose what the other person is saying for a second or two like the earphone is malfunctioning.
but the speaker works fine and signal is not an issue either
were you able to fix your issue?
I have the same problem with my phone since I remember. I got my phone around 3 weeks ago and flashed the latest Stable and Developer ROMs but the problem still exists. Like mentioned above by my friend, the quality is fine when I change to other operators in 2G, but in 3G and LTE its totally mess. I wish someone recognize this problem and fix this.

so sorry to hear that you have this issue as well
this is just unbelievable.... how can they just ignore such an issue? It's becoming a nuisance to sometimes impossible to use the phone to make or receive calls as I can barely make out what the other person is saying
Is there anyway we can complain about such issues?
Guys I found a workaround for this problem. Although it doesn't solve it completely. By this solution I succeeded making calls with much less noise and problem.
You have to turn the proximity sensor off for calls. It somehow solves the problem for now and make the calls much more understandable. Hope it helps you and get solved completely.
Me also facing same call quality issues

Same here no issues on China stable. Worse on global stable.. try typing *#*#995995#*#* wait 2sec and type *#*#995995#*#*(the same thing)again.. also go to settings installed apps find qti.supersaver open it and force stop these are like temp solution . If this helped please hit the thnx button
Thx for your sharing information but that didn't work dude. The problem still persists.
Guys I got a solution for myself. The problem actually WAS with the signal as I thought contrary. Yes, the 2G network works well because it has more strength with less range so its obviously works better than 3G. Hence, I started searching for a solution to improve the signal I get in my phone. The best thing I found was an app named "Network Signal Speed Booster" which boosts the signal you receive. Whenever I called a phone number after running this app, the call quality was PERFECT. This app actually connects you to the nearest antenna so the result is a better connection to the network provider. Please do this solution yourself and see if it works and notice the others. thx.
Thanks
Behrouz Your solution may work very well for me
I had the same problem
Thanks
My friend has issues with a Redmi Note 3 PRO speaker. He doesn't hear a conversation clearly. The person who he is talking with hears him perfect. Will "Network Signal Speed Booster" app help in this case? Some people says it's a fake program. Any new solutions?
Confirmed, Network Signal Speed Booster helps but temporary. I`ve noticed that it doesn`t matter of the network type,(4g,3g,2g), it happens only while the wifi is on.

Hi,
I have had the battery drain on stand by due to mobile network, but the latest official update (Oreo for Customized FR) solved it.
But I have another weird issue (Since the beginning) with photo addon... I am not able to add AR effect, the "+" button is not there so I have to live with the ones who came originally (dinosaurs and Fiesta things).
My wife is having the XZ and everything is fine... Grrr... Tried also many factory reset and repair via Sony tool on PC but none of them solved my issue.
I am partiently Waiting the Pie update to check if it corrects it.

Can't charge my battery without rebooting

Hi there, i have no idea what is going on with the cellphone, since i used it for the first time i tried to charge the battery without any success, i reboot it while the usb-c was connected and it did charged, so now every time i want to charge it i have to connect it and reboot it. Also if i disconnect it after rebooting and connect it again it wont charge until i reboot it again, seems like it doesn't recognized the usb unless i reboot it. Could someone help me? Thanks
Have:
- Android 9 PKQ1.180729.001

Install a custom Rom or MIUI10 latest beta build. If problem persists then problem is hardware related.
Been facing the same issue, @drchau did you find a fix for it ?
It is a hardware problem.. seems like it is somewhat common. I had the same issue last week. Tried several stock and custom os. Then realised it should be a hardware issue. Mine had same behaviour ( reboot to charge ) and then problem with otg not detecting. And usb c cable is recognised in only one way.
So booked a slot for service . Went to service today. Found three customers with same issues , and then the service center replaced my usb sub board and others too. Took one hour total. And everything is fine now.
Total cost is INR 700 for board + INR 350 for service + 19% GST. = 1250 INR.
They won't replace the port. It's a whole sub board . They replace it. You will get it for free if under warranty.
I have this problem with my Mi Max 3. I have to reboot OR for some reason it will charge via an OTG dock without rebooting (odd ... If I plug the same usb c cable in directly it doesn't recognize it.
A couple of times when I unrooted and reverted to stock unrooted, the charging issue went away.
I realize that many here are convinced this is a hardware issue but I also routinely disable/delete a lot of crapware and system apps via ADB .... Can't help thinking there might be a coded dependency issue.
I am in the USA so getting it serviced isn't an option ... I have 3 Xiaomi phones and would love to add a Poco F3 when I can afford to, but these charging issues are being reported with great frequency and I am hopeless at soldering.
If anyone knows of a repair shop in the USA they trust with their Xiaomi products I'd be grateful to know the name.
Thanks!

There's probably a couple mosfets and what not on that PCB. Maybe bad design or a manufacturing defect caused a solder crack or trace failure. Maybe a component.
These boards are usually inexpensive.
A relatively easy fix if so.

It could be (most likely is) a dependency especially if it happened right after the edits.
I prefer to package block rather than edit them out. Mistakes are easily corrected... most times.
Don't attempt soldering anything in these devices unless you know how to, not the place to learn.
Many though aren't soldered in, they're connected with ribbon cables more commonly. See a device tear down to find out.
A good phone repair shop should be able to handle it.

Thanks for your reply.
I'm pretty sure from video teardowns that the parts involved in the MM3 require soldering (there's some kind of board involved with replacing the port)
I still love the Mi Max 3 but it isn't worth a spendy repair because the carriers here are shutting down 3G and HSPA+ soon which only leaves me with FDD LTE 4 (not great where I live).
Repair shops aren't as expert in the states sadly ... most people here buy their devices from carriers.
I needed a camera replaced on my old Max but they didn't want to order parts so I ordered it and did the replacement myself (but only because I didn't have to solder).
If Asurion insurance from Amazon covers global phones I'll get my next Xiaomi insured. Too bad Xiaomi won't just let us ship at our own expense to their service centers in China or Europe.

Many times you replace the whole port PCB. If it's soldered on it could be a pain even with the right tools/experience.
You could try a factory reset to undo the disabled apks to see if that was it.
Thanks, I've tried factory reset and it helps for a little while. For now its still usable ... Rebooting to charge isn't a big deal. I do find it odd though that I can still charge via OTG dock without rebooting.
The bigger issue is what to buy to replace it. I don't trust Miui not to be buggy anymore and I have grown to hate constantly having to disable optimizations that inhibit sms, email and even calls (if I try to use TMO towers... AT&T MVNOs seem unaffected ).
I wouldn't mind doing all those steps once but my permissions don't stick for very long.
The TCL 20 might be worth a look...or maybe Realme if I see one with a bigger screen... I'm wedded to large screen models, mid price at best, with NA LTE band support ...
TCL also has a couple of LTE tablets with decent specs coming out ... but LTE tablets for USA export almost always ship with the dialers disabled so you can't make calls.
I'm trying to out till the end of June. By that time, hopefully the Poco F3 bugs will be resolved. Retailers aren't even shipping it here yet.

After the factory reset you need to find the akp that triggers this. Reviewing the most recent running and/or cache processes can narrow down the list.
Use Package Blocker PD MDM to clear the data in suspect apks. Unlike clearing the data in settings PD MDM leaves no nulls behind. Those silly nulls can mean big trouble.
Since it keeps returning the offending apk may be amenable to being package blocked depending on its function/dependencies.
This is how you find it.
Android Setup is a prime suspect. I cured a similar C-port error message like this by deleting the null marks in its data which showed as zero.
Happy hunting

My short story with Redmi Note 9S - Don't buy it by now.

I need to tell you my short story with the Redmi Note 9S.
I bought the phone at the beginning of may, my first Xiaomi with MIUI (my former phone is also a Xiaomi, but a Mi A1 with Android One) The first two weeks was working OK. I even red some reports about wifi and screen shadows bugs, but my phone didn't show these issues. I was very satisfied with the camera, the speed, and the amazing battery life.
However, around 20th of May it started with wifi disconnections with the screen off, almost every time that screen went off, the connection stopped. I assumed this bug was normal in a recently released device, and that it was going to be solved on the next software update.
Also, one of my smartphone main use is listening to music, through Bluetooth because I have the excellent Sony 1000XM3 headphones. Sadly, I discovered that my headphones, that sounded so good paired with my former Mi A1, sounded very very low with my brand new Redmi Note 9S. At full volume at the phone it sounded low with lack of punch and liveliness. Also, I was surprised that my dad's Redmi Note 8 showed the same behavior when I connected my headphones. So, I suspect from MIUI implementation.
The end of May came and so the first software update to my RN9S. I upgraded quickly thinking that the wifi bug was fixed, and the first days that was my impression. However, around the 8th of June it started again with the random disconnections -less than before, I need to say-.
Also, the Bluetooth bug wasn't fixed, even having informed Xiaomi about it, on official forums and through the feedback app. They requested me to send a logcat, with no further response.
Last weekend I installed the latest update, 11.0.9.0 QJWMIXM, hoping that, after two updates, the bugs was finally fixed. But no, there is no fix at all. Also, on official forums team members are saying that this update will be the last until MIUI 12, probably out in July.
Due to COVID pandemic, I'm working from home, using Whatsapp Desktop to communicate with my workmates. As you may know, WD need to have the phone permanently connected. But with this annoying bug, WD doesn't work, and I received the messages late.
So, frustrated with bad Xiaomi support, and problems with brand new device, I ended selling it, and now I'm going to buy a new, non Xiaomi phone. Luckily I still have my old Mi A1 as a backup, no MIUI of course.
I DON'T RECOMMEND TO BUY THIS DEVICE NOW, UNTIL ALL BUGS WILL BE FIXED.
Hope my short story serves as a warning to buyers, and a wake up call to Xiaomi. Care about your phones and your customers.
my experience, dont touch a Xiaomi phone unless its been out in the market for atleast 6 months.

A very good point. I also feel that I bought this phone too early, and we are all sat here wondering if the major bugs on our phones are going to be fixed. I won't be too hasty next time, I'll probably purchase something else too.
I am very happy with my purchase.
Consider installing a custom rom. I have not noticed any bugs + much more useful than MIUI: https://forum.xda-developers.com/redmi-note-9-pro/development/rom-evolution-x-ganja-curtana-t4094495

That's what my plan is, I love the phone but very disappointed with stock support. What amazes me is that the custom Rom devs can produce a custom build without the bugs, yet Xaiomi don't see these major bugs as a priority.
I really want to flash Evo X, but I want to make sure I do it right. At the moment I am reading about bootloops with some people that have tried it.
Sorry if this is off topic here but what were your exact steps flashing the Evo x ROM. Just bullet points will be fine.
I'm rooted with Magisk. I just need to be rid of these bugs once and for all.
First of all a disclaimer, the source code for TWRP for Note 9S has not been published. It may contain some malware or anything else. I am not responsible for any damage. I just tell what I did and it worked for me. Might not work for you.
PC is required to do the following:
" unlock bootloader
* update to MIUI v11.0.7, I got a fixable bootloop on other version (search MI forums or similar for the files. Update from system menu did not work for me)
* turn off phone
* enter fastboot with volume down + power
* install TWRP (search MI forums)
* copy Evolution X install file to SD card
* follow the instructions in Evolution X thread
The problem is that Miui Global is a terrible operating system, really horrible. Don't expect improvements with Miui_12.
Or wait for roms based on Pure Android (AOSP / LOS) or if you want to keep Miui raisins for rom Xiaomi.eu

I have had my Redmi Note 9S since mid-May. No issues like that all for me thus far.
No problem like the one you describe.
The sound is great. If it was low for you (as it was for me when i first connected my earphones) you must use both the phone and earphones volume slider to increase the sound.

Last weekend I installed the latest update, 11.0.9.0 QJWMIXM, hoping that, after two updates, the bugs was finally fixed. But no, there is no fix at all. Also, on official forums team members are saying that this update will be the last until MIUI 12, probably out in July.
Due to COVID pandemic, I'm working from home, using Whatsapp Desktop to communicate with my workmates. As you may know, WD need to have the phone permanently connected. But with this annoying bug, WD doesn't work, and I received the messages late.
So, frustrated with bad Xiaomi support, and problems with brand new device, I ended selling it, and now I'm going to buy a new, non Xiaomi phone. Luckily I still have my old Mi A1 as a backup, no MIUI of course.
I DON'T RECOMMEND TO BUY THIS DEVICE NOW, UNTIL ALL BUGS WILL BE FIXED.
Hope my short story serves as a warning to buyers, and a wake up call to Xiaomi. Care about your phones and your customers.

I could not finished up the epistle you wrote describing the issues you have experienced, but i'll say in my opinion that you are still new to MIUI, being an old miui user, there a settings that make the phone disconnects network connectivity either WiFi or Mobile data in other to save battery, Check settings- battery performance - and play around the options there. Cheers
Well yeah, but the wifi bug definitely EXISTS.
Read through the different boards and you will see how many users noticed the same behavior on their devices.
That's NOT a wrong setting that you simply can switch in the energy save settings of the phone.
And Xiaomi knows about this bug and they tried to give a fix in the latest firmware update, but for many it's more a "dirty workaround", cause wifi is still disconnecting after few minutes in idle, but reconnects after a few seconds in most cases. Its a dirty workaround, cause the constantly reconnecting all few minutes is draining battery unnecessarily and doesn't always work.
(Would be nice not to quote such a long post...its a bit annoying to scroll all the time to come to the new post itself ?)

Source your quotes. Where are you seeing that this is a common thing. This is the first I've read of it on 2 forums. I was also going to suggest the wifi to mobile handover setting as that has plagued me in the past because of my bad wifi.
Lol...are you kidding me?!?
You don't have to go far...a closer look HERE on XDA and you'll find the first thread with over 200 posts so far...!

And by the way, even Xiaomi themselves have posted that the update to MIUI 12 will "Adress the wifi issue"...
My short story with the 9S:
I did order the 9S 4/64GB with Gshopper on aliexpress, shipped from the Czech Rep.
It was really shipped from Germany (JKGC in Buchholz).
Now the trouble started:
- MIUI 11.0.7 Inserted SIM - data works, outgoing calls all go to "Emergency Number"
- unlocked BL and installed TWRP and crDroid - still data works, but all calls go directly to 112/911...
- flashed with MIUI the fastboot MIUI 11.0.9 - still the same...
- unlocked BL again and flashed TWRP and MIUI 1.0.3 EEC - still no call other than "Emergency Number"...
- Flashed Evo X - still no call other than "Emergency Number".
In Settings/Apps and../Phone the check box is ticked, so unfortunately this was not the problem.
Gshopper denies Warranty, only agrees to refund if I pay for return shipping and says I can buy a "new" 9S. Even that they sold a faulty product shipped from the EU(CZ) to EU(IRL)...
EDIT: found a partial fix, see here: https://forum.xda-developers.com/showpost.php?p=83114093&postcount=2
I just got this phone and am pleased with the hardware and performance coming from a Zenfone Max Pro M1 but it does seem a bit buggy (random app freezes a couple times, and some games like Sonic the Hedgehog 1 and 2 refuse to start). Hopefully these get patched quickly but I will probably use a custom ROM once updates cease.
Is the WiFi bug a problem in every phone or just some of them?
If it's just say 10% of phones then I don't mind taking my chances.
If it's every phone then it's not worth it.

Well, I guess you can have the problem with every device of this model.
It more depends on the combination of the device and the router you are using.
Most of the users facing problems are using a fritzbox router as far as I know.
I'm using a router from vodafone for example, and have no bigger problems with wifi on my phone.

I use a "Vodafone" router too, a Huawei HG556a and openWRT. No problems to use the hotspot and "relay" the Inet to my home network.
In my case I had to downgrade to 11.0.7 first and then install crDroid. After that WiFi and hotspot worked, which it didn't with 11.0.9 as base. I tried LOS from telegram and that worked well from 11.0.9 as base.
