Bad WiFi and mobile data signal after display replacement on Mi A1 - Xiaomi Mi A1 Questions & Answers

Hi all,
I recently exchanged the display on my MI A1 and since then, the WiFi and Mobile internet signal quality is horrendous. It still works when I'm close to the router or in an open area, but often it doesn't.
Is it possible that I might have forgot to connect a connector or broke of a part?
Does anybody know where the wifi antenna is in the MI a1?
Thanks in advance

Any hint? I have heard that there is a pin that could have been curved but I had no luck in finding it?
My front cam is also broken :/

Same problem happened with me brother. I have repaired my smartphone in January 2019. And from then my wifi, bluetooth, gps, mobile data nothing is working perfectly. Still didn't get any solution yet.

D5+ smartwatch connectivity issues

I've recently bought a D5+ and even though the first few days it was working fine, suddenly it started loosing Bluetooth connection with my Note 3 smartphone, Wi-Fi connection was limited or missing and also mobile network was dead. I've been in contact with the production company where they suggested upgrading the firmware to the latest version. That is what I did and unfortunately the problems are still there! There seems to be an antenna issue. I've noticed that when I bend the wear strap, the signal improves significantly but the mobile network is still dead. Any suggestion how can I resolve this out would be highly appreciated.
Thanks in advance.

Hii everyone,

Thank you.

Blutooth affects wifi connection speed.

Hi guys have you ever tried using your m3 for streaming connected to a blutooth speaker or headphone? My speed drops to 80% and becomes unstable once i connected my blutooth to a device.. do you have this issue as well? I mean from 80mbps it drops to around 5-20mbps it is ridiculous
This has been a huge issue for me. Most of the info I have gotten about it online says that the 2.4ghz wifi and Bluetooth are known to sometimes interfere with each other. That is my major reason for wanting to root this and enable the 5ghz band. I have already changed the wifi channels on my router and that didn't work. I guess I am gun shy about rooting since it has been a few years since I have done it and I haven't seen a comprehensive root guide for this yet (not looking too hard yet).

So does this mean that this has been an m3 issue? My Note 5 does not have this issue. It is so annoying I cannot properly play spotify and at the same time use my blutooth speaker. what a waste .
Have you tried resetting it?
Even turning it on... affects wifi
Even if it is not connected to anything. If I just turn it on wifi speed becomes very slow....
All I can say is that it is definitely noticeable when Bluetooth is on, I have a 200 megabit bit connection, it will buffer Netflix almost unwatchable. I did some quick Googleing and found lots of references across many devices saying that there was interference. I have not reset the device, after seeing it was a known problem and not necessarily device specific I figure the hell with it. Again, rooting and turning on the 5ghz wifi on the M3 solves it.

Tried hard resetting the unit. Same issue... once connected to my blutooth speaker it degrades my wifi internet speed to almost 90%.
Post #23 on the forum linked below tells you how to enable 5ghz network after root. If you successfully root I would love a tutorial or link to instructions.

but I have the BTV-DL09 model.
The DL09 is the lte international one, correct? Then I believe you have the ability to use 5GHz out of the box. You just need a router that puts out 5ghz
Sent from my BTV-W09 using Tapatalk
That's what I am planning to do. But isn't weird that using the 2.4 ghz wifi and blutooth cannot work together? Im hoping for a fix for this one. I refuse to buy a new router just for this. My god! ??
I bought the BTV-DL09 (international) version and experiencing the same. I am connected to a 5Ghz network and speed drop from > 200Mbps to < 40Mbps (sometimes less than 20 Mbps) as soon as I enable Bluetooth. This sucks as I use Bluetooth headphones and sometime audio stutters too and definitely looks like there is interference between Bluetooth and Wifi

Same issue on BTV-W09. I've been on chat with Huawei for this issue multiple times, and they want you to delete cache and/or reset unit to resolve this issue. This is a bogus solution, as my two recently purchased Mediapad M3s have the same issue after trying this fix. I have a 20mbps download, and can achieve close to that with bluetooth off.
With it on, if often tests lower than 5mbps--quite terrible. Netflix becomes unwatchable with bluetooth headphones.
According to a Huawei agent, the bluetooth and wi-fi antenna are the same, and it is "normal" to see this slowdown. I'm wondering if it is normal to purchase a media device that won't stream properly when using bluetooth headphones? Hmmm, should't promote this as a media device but as a reader if that is the case.
I'm suppose to communicate again with Huawei tech support on 12/05/17 as they further research this issue. They seem unaware of it, so it wouldn't hurt if all users on this thread would contact there tech support and complain--ask for a proper solution.
I spoke to Huawei about this issue and they told me it was a hardware issue that the tablet should not be having. The agent said to send it in to them for replacement or to exchange it where I purchased it. He said a new one shouldn't have the same issue.
I plan on exchanging it, but I'm wondering if anyone has an M3 that doesn't have this issue. It's gonna be a bummer to exchange it only to have the same problem.

Did you ever have any luck with this. I am having the same issue and Huawei is basically saying the same thing, send it in for a hardware fix. Has anyone had this device successfully repaired?

Yeah, me too, waiting for an update. I have toggled Bluetooth on/off, location on/off it only really becomes a problem when Bluetooth and wifi are on at the same time. Wifi crawls. If I found an easy way to root it, I would then allow 5ghz and be done with this.

Not JUST WIFI, EVEN SIM INTERNET SLOWSDOWN
i have done many many tests with bluetooth on n off, when bluetooth is on i am 100% sure it affected BOTH wifi and internet from my sim card BIG TIME. Lesson learned, will stay away from this brand

Hi!
I use 5ghz and still face WIFI crawling with my BT headphones.
Pretty ridiculous problem from Huawei IMHO. Like we are back in 90s.
Oh, that's unfortunate, I was hoping the 5ghz would solve the issue. Well, the bright spot in this is that I only really use my Bluetooth QC35II headphones when I'm on an airplane and in airplane mode so not too much of an issue there.

Apparently the new M5 has this problem too.

Can't connect to GPS satellites

From few days ago my phone started to lose GPS signal, now with every GPS test apps I can see the satellites but it didn't connect to any. I tried different ROMs, came back to MIUI but nothing changed. Is there a way to restore connectivity as I think it's a software problem because I can see satellites, so the antennas work but don't connect?
Have a similar issue, started losing connection to GPS satellites, while using in the car.
Please search first
https://forum.xda-developers.com/redmi-note-7-pro/help/redmi-note-7-pro-gps-problem-t3960702
Same thing here .
Tried everything
Going to replace the phone
Update:
After one day GPS started working again without doing anything. Maybe it could be related to Android auto as I'm not using it for 2 days and my problems started when I was using it
I am currently on Atom OS and have that issue of not working GPS every time I reoot. Have to disable location service (in quick settings) and reenable them for it to work, This is probably already solved in an updated version of my ROM, but hey, it's a quick try.
I have a similar problem, but I already have several months with my redmi note 7 and after moving to miui 11, the GPS works irregularly. I have seen many comments about problems with the GPS, but I have not seen any explanation from xiaomi
Enviado desde mi P008 mediante Tapatalk
the GPS stopped working properly as if there was not enough signal,
how did you solve it? I see the satellites but a small signal and disappearing.
hardware repair - how?
or software? (goes downgrade miui?)
After update to Miui 11 i hve similar problem with my gps. I'm using app from Play stone - GPS FIX/OPTIMIZER and work fine. If i have problem with gps, run the app and restart.

thank you, the signal is better but still not good. In the woods I used to run when I had my cell phone in my pocket and the signal was OK, now the signal is lost

I'm looking for, but I can't find anywhere, even google didn't help me much
I do not have smart lock in setup / password and security
where it should be in RN7, miui 11
I'm on Cdroid and i find smart lock under security. I had MIUI before and i Remember i had Smart lock too. When you connect a new bluetooth device system should ask you about Smart lock. Try ti search in options
Hi guys
I was having the same problem with the gps connection. after changing my region settings from Brazil to Argentina, the gps returned to work correctly. test by changing the region and always restarting with each change.
My rom: V11.0.5.0.PFGMIXM (MIUI11)
I tried everything
also unlocked the bootloader and tried other rom
fix is not a problem, but the signal is still weak (large inaccuracy), with most satellites up to 20snr
a month ago there was no problem, I suspect the gps antenna, but I do not recall any phone crash, etc.
unfortunately I find nowhere manual, video, where the antenna and how to fix it

try to change the region, restart your smartphone and check for any improvement in the gps signal.
I tried everything, fix is no problem, I catch 12 sometimes more satellites (in open area), but all with low signal. Just go under the edge of the tree, and the signal is very weak and very inaccurate.

Honor band 5 - reconnection issue

Hello.
I've got a problem with my Honor band 5.
After leaving range of my mobile bluetooth, band lost connection.
But the connection won't be reestablihed after return to the range. I have to turn at least locksreen on, to reestablish it.
I think this is uncorrect behavior.
My previous Xiomi band 2 doesn't have problem with this. Even in a car - when enter, I don't have to do nothing and connection to handsfree is established.
My phone is samsung s9.
Where can be a problem?
I have the same problem. The band will only reconnect if you turn on the GPS signal.
Thanks for answer but this doesn't help.
No matter, if GPS is on or off.
I'll try it on another phone, I've got an old ZTE Axon mini here...
EDIT: It ends as same behavior. So issue is not caused by phone, but by band. Or by Huawei health App.
I think it is caused by health app. So I can't do nohing, unless Huawei fix it. Until this - my band is useless.

Do you update it?
Yes, there was an update at the end of the february.
Unfortunattely, it doesnt help.
Now it seems it is samsung issue...
I've tried band with two other phones (ZTE Z17 mini and some old Xiaomi) and band reconnect right after returning to phone range.
On both phones...
And I tried on another Samsung S9 and same problem.
I'm bit confused now.
I use a Samsung S8 and my Huawei band 4 PRO reconnects automatically as soon as I get back to Bluetooth range.

Hi, I create similar case on new subject:

I invite you to discussion
The huawei health app notification must be enabled on the phone.
