December 2020 security update is now available - Xiaomi Mi A2 Lite Guides, News, & Discussion

Hi,
Just received it, but only 3,6 MB. So I guess none of the bugs have been fixed.
Cheers

Updated today, did usual reset through recovery, my daisy works fine. Atm zero annoying tips in settings.

Will the December update fix the multitasking bug on Mia2 lite ???

So I just updated to V11.0.16.0 via fastboot.
I am still having the same problem (since my first upgrade to Android 10 about a few months ago) with my Wi-Fi. Every 20-30 seconds, Wi-Fi connection is lost. Then after a few seconds of waiting, it is established again. Then after 20-30 seconds, Wi-Fi is again lost. It goes on like that, endlessly until I just deactivate Wi-Fi and use mobile data... but this cannot be the solution, don't the Dev's have to notice something is wrong with Wi-Fi??
Is anybody else having the same problem with Wi-Fi?

Before upgrading to Q, on P, zero wifi' s issues ?
Maybe something' s changed in your area, new wifi signals could interfere with your device.
Have you checked other devices, like a pc or other mobiles ?
If your router is dual band you might try 5ghz, daisy works fine in my experience on 5ghz regardless of android version.
Did you try a reset from settings or recovery in these months in search of improvements ?
Personal curiosity, why did you use fastboot for updating your device ?

I only have a 2.4GHz router, but the problem is happening no matter which channel I choose on the router setup (i.e. the frequency within the 2.4GHz band).
We have several Wi-Fi devices in this household, including Wi-Fi repeaters to strengthen the Wi-Fi signal around the house... end user devices include multiple notebooks that use Wi-Fi access, a Smart TV and I also use another smartphone as a backup (Nexus 4) and neither of these devices does have any problems with the Wi-Fi.
Also, my brother is using the same phone the same way (with fastboot flash every time there is an update available) and he is having the exact same problems with Wi-Fi on his Mi A2 Lite.
Also, the Wi-Fi issues are the same when I am at the library and connected to a different Wi-Fi. So in my opinion it is unlikely that there is a problem with the Wi-Fi at home.
Around the time the Android 10 update became available, I started activating Bluetooth on my device 24/7. However de-activating Bluetooth has no effect and my Mi A2 Lite still loses Wi-Fi connection just as often.

Reset from settings only, but it should not matter because I am flashing all partitions every month, whenever an update is available and the problem is happening as soon as I completed the flash and started the device for the first time.

I am using Magisk to gain root access to this device. There is a guide on XDA that I follow for doing the update via fastboot, so that I can continue using Magisk. As far as I know, OTA update still fails when any of the partitions has been tampered with, for example by installing Magisk and patching boot.img.

If the wifi' s issue began for both devices, yours and your brother' s one, after you decided to use magisk on stock rom it could maybe be the monthly flash procedure the reason of such problem.
Have you tried to flash a custom rom and check if issue continues to occur ?
Personally, as reported, i' m using 5ghz wifi without any issues, zero disconnections on last stock december build.

I think I was not as clear in the post above. We have both been using the Mi A2 Lite with Magisk and Android 9 since December 2018. So we used Magisk to root the phones right when we got the phones. We had no issues with Wi-Fi on Android 9 with Magisk. Only when we updated to Android 10 in spring/early summer 2020, we encountered the connection issues.

I did not do that because most Custom ROMs that I found for this device have problems on their own with some features, and I like having a nearly stock Android experience. However, I get your point that this might be a good opportunity to check whether or not this is a problem with the official Xiaomi ROM or the Mi A2 Lite's Wi-Fi modem, i.e. a hardware problem maybe.

Could you check if your Mi A2 Lite works on 2.4GHz Wi-Fi without disconnection issues? From my experience, 5 minutes of testing would be enough. Usually I see the first disconnections within 30 seconds after I activated Wi-Fi (2.4GHz) and disabled mobile network.

Checked rn, 10 mins on 2,4 ghz, wifi works fine, zero disconnections.
About custom rom, you could try los17.1 from Reujea0 or crdroid from Opal. Imo los and crdroid roms are very close to stock experience. Moreover, i recently read on los17.1 thread that dev would like to switch to next release, los18, anytime soon.
And yeah, you should avoid it isn' t an hardware failure.

Thanks for checking this out and getting back at me. I did some further research, as I found out that another user on mi.com (the official Xiaomi forums) reported that when updating to Android 10, he had problems with switching between WiFi's (switch took a long time, download/uploade rate on WiFi very slow, https://c.mi.com/thread-2854872-1-0.html).
I then disconnected the repeaters on my network and found out that WiFi on my Mi A2 Lite is working without any problems, as soon as the WiFi router is the only WiFi host and no repeater is used to extend the range of the WiFi network. Maybe there is a problem when the device is handed over between repeater(s) and router within the same WiFi.
The Mi A2 Lite is my daily driver. As soon as LOS reaches official status, I will flash it on my device and try it out. For now, I will just continue using Mobile Data.

I think after update phone has less lag. Still have to reboot, but it is a little better

Nexus 5 WiFi 802.1X EAP (PEAP+MSCHAPv2) Not connecting

I've been trying to connect to my college's wifi for the past 30 minutes and I still can't seem to get it to connect. I copied the settings straight from my Nexus 7 that is running 4.2.2. I might install a custom kernel right now and see if it alleviates this problem.
Does ist?
Nexus 5 android L factory image same issue, i tryed with every version of the preview and official image and doesn't work.
With kitkat work perfectly and custom kernel don't solve the issue
I flashed yesterday the official build and it doesn't connect to a network like the one you described. I guess they need to fix some things, this is not acceptable.
I have the same problem on Android 5 on my Nexus 9. But my Nexus 5 (upgraded from KitKat, not freshly installed) connects fine to our work WiFi (PEAP).
Really? Wow, but i cant believe that nobody had the same issue while preview.
Do you have the MASCHAPv2 Authentifiaction?

Hello guys,
I can confirm this has been happening since the "preview version" on the Nexus5, we've the same configuration (PEAP+MSCHAPv2) and we've the same issue with our wireless network with these devices.
But why doesnt google know it?

I posted that logcat with my friend
I've tried to configure our Wireless LAN Controller with WPA2 EAP-TLS+CCMP support and this configuration it's working well for our Nexus 5 devices. I don't know if you could configure your wireless network with this encryption support but you should consider it.
I know nothing of these wifi protocols but what I noticed is I cannot connect to networks with secondary login on a Web page.
I am freaking out... All networks at work are like that and cannot connect to any.
This started happening yesterday after flashing the 5.0 image.

Hello Steve,
That's the same issue that was affected to me until that I tried to use WPA2 Enterprise with EAP-TLS+CCMP encryption for our Nexus 5 devices with Android 5.0. Would you be so kind as tell me about your wireless access point model and manufacturer? I could try to explain how you can configure your network in order to resolve this issue or at least say if this configuration is possible with your wireless access points.
Regards

Will get all the info I can but I am working night shift so it will be hard to get info. Access points are all like 30 feet high so I cannot just take a look. What I know it's a Bell Canada network if this is any help.
One thing is sure is that the network will not be reconfigured for me to access it. I will need to adapt to the network. All was fine on 4.4.4.

I understand your situation but the PEAP-MSCHAPv2 is broken now with Android 5.0. I think that your unique option if you don't want to change nothing in your wireless access point infrastructure, is perform a downgrade to 4.4.4. This is obvious, I know.
Anyway you should consider to study change your wireless security to EAP-TLS+CCMP in order to avoid some issues inherent of MSCHAPv2 protocol related to some protocol vulnerabilities that could permit to attack your wireless network with a brute force attack.
I'm not familiar with Bell canada Network but it's possible that you have a wireless lan controller in order to centralize your wireless lan management, probably that wireless lan controller have information about your access points.
That seems to be the problem.

Yeah... I can confirm that these issues are only with FLASHING factory images. I tried that and it didn't connect to my work wifi (CISCO routers). But my friend did OTA update. Its working fine for him.
I think there is some problem with factory images. Going back to 4.4.4 for now, and will do OTA.
I tried following:
Flash 4.4.4 Factory Image.
Wipe Data and Cache.
Sideload OTA 5.0.
Wipe Data and Cache.
But I cant connect to eduroam WiFi. MASCHAPV2/PEAP.

I actually flashed the factory image. But without wiping everything aka. dirty flash. Connecting to the WiFi at work still works great.

that may be the problem. i completely wiped the system. and its not working for me. dirty flash is more like OTA right? but manual, may be that previous settings are making it to work. when completely wiped.. its not able to connect.
Remove "pmf=1" from /data/misc/wifi/wpa_supplicant.conf and reboot, wifi works. Root required.

[Q] wifi and mobile network keeps disconnecting

Hi
i'm having some issues with the radio on my Nexus 5, it startet after i upgraded to 5.0.
I did this by first deleting all user data (i use stock fw, no root), then by flashing the factory images with fastboot.
What happens is that wifi keeps disconnecting very often, like every 2-3mins.
if i turn wifi off, the same dropout happens with the mobile network..
I thought this was just a bug that would be fixed in later releases, so i waited.
5.0.1 OTA popped in and did not fix my issue, so i did a factory reset (read that in 5.0.1 android resets more thoroughly).
Still it keeps disconnecting.
now when 5.1 was released i flashed that image (didn't edit the flash-all.bat file so there was another wipe), it still disconnects.
Can anyone help me diagnose this problem (i can try to do a logcat?) can i flash the old radio from 4.4 safely?
is there anyone having the same problem like me?
I don't have quite those symptoms, but I do have a Wi-Fi problem, ever since 5.0. My Wi-Fi connection drops at random times. You can see the drop outs on the battery page, and it just stops whatever network activity was happening at the time. If I'm using Chrome, I know it's going to fail when the progress bar goes to about a cm then stops. If I toggle Wi-Fi off and back on, or sometimes if I simply wait for about 30 seconds, it works again. With 5.0.1, I was using the 4.4.2 radio, which was a lot better, dropping the connection a lot less often. I hoped 5.1 would fix it, and it's better, but it still happens sometimes.

My problem has, though it is worse on some networks. It's worse on my own home router, for example, which is an Asus RT-N66U running Merlin firmware. It happens less often here at work, but it has happened here. Both of these networks are 2.4GHz only. It happens just infrequently enough that I can live with it, but it's annoying.

My N5 WiFi is always rock solid on baseband M8974A-2.0.50.2.22 on 5.02 Euphoria.
I connect regularly to an Asus RT-AC66U router @ 2.4GHz running Merlin . So I doubt its' router related.

Well, i only use wifi at home so i'm not sure.
I've been testing with wifi off at home to rule out wifi, but it keeps disconnecting on mobile network as well.
It doesnt happen during calls, just while browsing etc, using mobile data.
It also keep switching between LTE (with low signal -117dB) and Hsdpa (better signal, -117) so i tried locking it to use only GSM/CDMA, that didn't help either.
Now i tried setting up my old router to try anoteher wifi network, no luck..
Guess i must try kitkat radio, see if that works any better
edit: that didnt work either

I've been trying to isolate this problem forever, and I'm starting to think it is something about my router, after all. Could you possibly post the settings from your Wireless General and Professional tabs in the Merlin firmware?
I now have a perfectly stable phone. Nexus 5 with 5.1.1, rooted, TWRP recovery, Xposed alpha, otherwise stock. I found the source of my Wi-Fi disconnect problems: it was my Belkin WeMo switches! I unplugged them, and I haven't had a disconnect in over a week. I haven't experienced a single other problem with this setup. (knock wood)

Wifi connection troubles after update to 6.0

I'm not sure if this is a Nexus 5 problem or a 6.0 Marshmallow problem but the problem occurred after the update to 6.0 on both Nexus 5s for me and my wife.
There seems to be some bug with my phone while it is asleep (screen is off but phone is on). When it is in this mode, it will not stay connected to wifi. For example, when I enter an area that has wifi, my phone will not connect. It will only connect when I wake the phone. And this isn't just a matter of the phone taking a while to connect. It NEVER connects. Before the update, my phone used to make a connection with my home router before I even walked inside. Now, I can be inside for hours and the phone never connects, until I wake it up. As soon as I wake the phone, the phone makes the connection with no problem. After a few minutes of the phone being asleep, I will wake the phone and the wifi connection will be gone. Now that it is awake again, it connects again with no problem.
I have tried forgetting the network and creating a new one, I have tried different routers, I have tried wiping the cache partition. I haven't tried a full factory reset, and I'd prefer not to, but I guess I will if I have to.
Just thought I would check here first and see if anyone had other thoughts.

Thanks for the reply. Yes, that is what I thought at first also. I meant to say in my original post that my wifi settings are set to "Always On" during sleep. I've tried toggling that between the settings but still have the trouble.
Sorry, my Nex 5 has not this issue on Android 6 build MRA58K.
Alessandro
Yup, have the same issue. When the phone goes to sleep, it seems to disconnects from the wifi and never connects after I wake the phone. When I go into the wifi settings, I see "WIFI Connection Failure". I have to reconnect manually. Like the OP, have it set to always on as well. I also know it's not a router issue because I've tried this on four different routers (two linksys, one Dlink, one TPLink) All same results.
Wonder if this is a phone issue?

Google upped this to a high priority Friday morning (Nov 6). The bad news is I think there a couple different WiFi symptoms being discussed here. Most of what is being discussed is the issue being discussed here (not reconnecting when the screen is off).
No idea when this will be fixed, so I build a Tasker profile to toggle WiFi every 15 minutes when not already connected to force a reconnect. I’ve observed it getting disconnected on its own overnight. This should avoid unnecessarily using cellular data.
I’m perpetually waiting for the next release of Android to fix annoying bugs.

Thanks for the update Gary. The comment #6 describes my situation exactly. In doing some troubleshooting of my own, I find the disconnection trouble to happen less while on a 5Ghz network vs 2.5. I still have the trouble of it not connecting initially when I come into range, but I find that it is able to hold the connection while asleep.
I am also experiencing this on my Nexus 5 and also found and starred the thread above.
I just listened to 20min of streaming with Spotify to then realize that it had gone into Doze and used the mobile data!
This is more than annoying...
Maybe by disabling Doze for some specific connectivity-related system app? Anyone tried that?
Yes, I moved virtually all of the services type of apps (the ones with the green generic Android icon) to the battery not optimized list. It didn't make any difference for me.
In some ways it seems like it might be a Doze problem, and in other ways it doesn't. Doze shouldn't be affecting anything when the phone is in my pocket and I walk in the house to my WiFi. It also shouldn't be affecting anything when the phone is being charged, which is when I see frequent WiFi disconnects.
It will be real disappointing if this isn't fixed with 6.0.1.
This is still an issue with 6.0.1. Nexus 5 (2013) 6.0.1 MMB29K updated through OTA ZIP pushed with ADB.
Things work properly for a while right after a reboot and then WiFi never connects until the screen is turned on.
Google Connectivity Services C.1.6.7 (2466695) update didn’t make a difference either.
Same problem as the thread starter. HTC A9 anroid 6.0. (newest available OS)
Same problem here with a Nexus 5 .
Please star the problem if you have it.

Has anyone tested with a non-stock kernel ?
I'm asking because the problem seems +/- resolved on CM13 (non caf).
No counting CM13, do you know of a more stable rom with the problem resolved?
Does anyone here have Wemo devices? I am reading that wemos, and possibly other devices that emit their own wireless network, may cause problems. I have several of these devices around the house, and wonder if that might be contributing. However, that only would solve the dropped connection bug I have, not the failing to connect while asleep but I have.
Hi mates, my Nexus 5 (android 6.0.1,M8974A-2.0.50.2.29) gets the same troubles with wifi connection but today I tried to put some apps in non optimized list of Doze and seems workig fine.
Thats my non optimized Doze list:
-Google Play Services
-System UI
Try it and let me know if it works properly.

I had Google Play Services already set to not optimize, but hadn't tried System UI. I will try that out and see what happens.

Welp, that didn't work. Still have the error after not optimizing System UI in addition to Google Play Services.
I don't know if the issue is resolved, but at least for me, it never worked fine so many days after testing some new workaround.
So, this was what I did in my Nexus 5 (latest build, MOB30H).
Uninstall or deactivate Google Connectivity Services, reset your network settings (you will lose your Wifi networks and BT pairings), reboot.
My Nexus 5 has been connecting to the wifi networks even with the screen off for the last 6 days.

Miguun, has the error returned, or still fixed? I just got the May update, so fingers crossed that fixes it. Otherwise, I guess I'll try your fix. I don't look forward to entering the wifi network information again.
Yup, it is still working !!

Problem - connections fail intermittently with Android 10

Hello everyone,
Ever since I upgraded to Android 10, my connections (mobile, wifi, Bluetooth) go off constantly, always when I'm doing something for a minute or two and then go back on, like someone is turning on airport mode. The upgrade was official (through system updater) and even when OnePlus support flashed some official "rock stable" according to them version, it still happens. Sometimes rarely, sometimes very often, no rule as to when.
Has anyone had this problem, does anyone know what causes it and eventual solution?
Tnx
Go back to pie. Android 10 stinks.
How? According to the support guy, it can't be downgraded, do I have to root the phone?

I have similar issue, I have discovered that it is related to mobile data connection, when I turned off mobile data there is no problem with network connections - it is no matter that I have WiFi and mobile data active - problem with losing the signal came from time to time, when I have mobile data off and WiFi signal is stable.
The problems also affect calls - when mobile data is active phone from time to time losing the network signal and disconnecting the call.
Did someone find a solution for that ? I have tried to change someting with APN settings but it is not helping. I have read about this issue on oneplus community but no answers with solution for that

Try downgrade to pie.If the issue still persist may be there is a chance of hardware related.
For me the problem only started happening after Android 10, 9 was all good. Although, the latest 10.3.0 I found on oxygen updater seems to help - doesn't eliminate problem completely but it happens much more rare. I've also discovered it happens more often in specific apps (db navigator is one example, an app for German trains).
Is there anywhere a description on how to restore exactly the factory Android 9? I always get the error "downgrade not allowed..." Even though I have advanced in oxygen updater turned on, thought that was going to solve it.

Question (SOLVED) WiFi5 866mbps only reached in airplane mode after reboot

Hi everyone, yesterday I decided to upgrade from the Redmi Note 8 Pro to the POCO X3 PRO, and everything is ok except for the wifi link speed, in my old Redmi Note 8 pro it was around 433mbps but in the POCO is 192mbps less than half the link speed.
The reason why I care about this is because I use Wifi File Transfer Pro to send and receive files between the PC and the phone because it's way faster than the USB transfer protocol even at 192mbps.
Update: I can reach 866mbps after a reboot in airplane mode no matter if I change the network to 2.4ghz I can always go back to 866mbps, but as soon as I disable airplane mode and my connection falls below 200mbps (whether it's by distance or by switching to 2.4ghz) I'm unable to go above 192mbps in WIFI5.
Temporary fix is to reboot with airplane mode.
Roms where this happens in my phone:
Official rom (International, Europe, India)
ArrowOS
EliteOS
Xiaomi.eu (current rom)
Any Ideas?
Final solution
So after a long time trying to fix this problem, I found the solution, it worked in MIUI 13.0.7.0 global.
You have to root your device with magisk
GitHub - Magisk-Modules-Repo/wifi-bonding: Double your bandwith on your Qualcomm devices.
Double your bandwith on your Qualcomm devices. Contribute to Magisk-Modules-Repo/wifi-bonding development by creating an account on GitHub.
github.com
Install the above addon for magisk
Reboot and now the phone will reach 300mbps on 2.4ghz
and 866mbps on wifi 5ghz, I haven't tried wifi6 yet
(Why would you want to do this?)
Well most xiaomi devices are USB2.0 and when you backup before restoring the device, the backup at least in my case took 80gb, and when I moved it to my PC it took me forever at 27mbps in a usb3.0 port, same when I use 2.0.
But when you use wifi file transfer pro, you can get transfers around 70mb/s in 5ghz almost 3 times faster.
So you will save a lot of time in large file backups and transfers.
Maybe try different app? The app seems old.
First check when you connect WIFI 5G and test the speed of internet.
Is PC wire-connected to router or through WIFI 5G?

1-The app is old and simple, but it does its work, the problem is the link speed that limits the connection.
2-This is not an Internet speed problem, it's about the link connection between my phone and the router (max theorical speed).
3-PC is wired connected 1gbps ethernet cable, I can sed files beween the local network at around 120MB/s (1gpbs)
My old Redmi Note 8 Pro link speed is 433mbps and it sends an receives at around 40mb/s, the new POCO Sends and receives at around 12-20mb/s

1. Compatibility issues between Android versions?
2. To check if your WIFI 5G is fully functional on POCO X3 Pro at full speed through internet.
3. So rule out PC and it's link to router issue. Cause still to be found.

1-The APP works fine, the app it's not the issue, the problem is the link speed that limits the app.
2-The 5ghz wifi it's fine, I attached the screen captures where the Redmi is at 433mbps and the POCO is at 192mbps.
Router is set on channel 36, bandwidth 20/40/80mhz, MIMMO enabled, and the distance from the router is less than 1m, same problem with the repeater (which allows around 1gbps speed over 5ghz wifi).
So far seems like a hardware limitation, it could help if you share your 5ghz network info to check your theorical speed.

It's not an in app MIUI restriction, please if you can connect to a 5ghz network and share the same screen capture as above, that would be useful for me.

When you unlock bootloader, your phone will be like a factory reset. If after that is still not fixed, I don't think flashing different Rom would fix it. Hardware issue or compatibility issue may be possible.
Try reboot both router and the phone. (power off, then manually power on with pressing power button.) Sometimes it will magically fixed.
Reset phone connection setting (should be in factory reset menu), then add WIFI setting again.
Find another router with 5GHz and connect to it to see if it's actually your phone's problem or router problem.

So after researching, reading trying everything, up to this day I've been unable to fix this problem.
At this very moment I'm in safe mode (Xiaomi.eu 12.5.3) and the connection is 866mbps.
I'm able to switch between 2.4ghz (192mbps) and 5ghz (866mbps).
Now there is one thing that I just discovered, if I boot with airplane mode, as long as I have it enabled I can switch between 2.4ghz and 5ghz without any issue, but the minute I disable it and try to switch, I'm unable to recover the link speed.
Video showing the issue

According to your update, you said ArrowOS and any MIUI ROMs had the issue.
Tried other ROMs?
If all the ROMs you tried had this problem, it may be firmware/kernel sourced and maybe Android 11 issue.
I think I've seen some people on this phones or other phones had WIFI issues, and had reported improved or somewhat compatible when without using mobile data and changing WIFI router to 802.11 a/b/g/n which is old and better stable, but may have slower speed.
If MIUI has this issue, you can report to Xiaomi with your video.

Yes I tested all the roms for the same purpose just to check the 5ghz link speed and all of them resulted in the same 192mbps what kernel do you recommend me to start testing?
I don't know, following my logic I've come to think that my phone has a hardware problem, maybe interference or a bad contact in the antena and the link gets throttled down to prevent data loss, but that's just a theory however I want to fix it.
One more thing, my brother has a Redmi note 10 and my mother has a Redmi Note 8, and they both experience an identical issue, but they are limited to 96mbps (half my throttled speed 192mbps), and if the reboot with airplane mode and wifi enabled, they both reach 433mbps (half my full speed).
So I'm almost 100% sure that there is a problem with the kernel or the modem firmware that's causing this, I just want to find out how to fix it once and for all.

Some Custom Kernels are listed in the Index thread, you can try to see if any would help, some custom kernels may only be accessible in Telegram group.
I'm not a developer, and not into coding, so can't help on solving. You can try and ask in Telegram group to see if some developer knows how to fix it, and the response there should be faster than in XDA.

Just tried Etherious kernel 3.0 (3.1 was incompatible) but no use, 192mbps persists, perhaps it's just a firmware/modem problem, probably I will be selling this poco and purchasing POCO F3 instead, hopefully that phone works better :/

I would say try a non-Xiaomi phone to test.
All your phones you listed are Xiaomi-related brands, and all had similar issues.
If you buy, lets say Samsung, and the problem still exists: it's more likely your WIFI router's problem.
If Samsung phone or other brand Android phone does not have this issue, it's more likely Xiaomi's problem.
You can still buy Poco F3, but it's not easy to find where there problem is from if test only with Xiaomi-related brand.
You can try iPhone as well, but since iPhone are completely different design, it's not easy to find out where the culprit is.
Everything depends on the antenna and the modem used in the device. It should have been optimized to work at 2.4 Ghz (which is actually good as 2.4Ghz is used more then 5Ghz in most cases). The airplane mode is not an issue. When it is turned an and turned off later, the modem is triggered immediately in which gives you a spike in speed. Just like, if you take rest for a while and run, you run faster then when you keep running straight!
