[Q] Unknown App Flashing When Toggling Wifi

Last night I was at home and noticed my wifi wasn't on, so I used the quick settings in the shade to toggle it. After a few seconds, wifi connected, and some unknown app took focus and closed repeatedly. After a few moments, it stopped and all was well.
I thought it was strange, so I turned wifi back off and the same thing happened. I rebooted, tried again, and got the same result. I was trying to think of a way to see what was happening, so I tried using the Screen Record function in Gravity Box, which didn't help much, because it happens so fast, and no info is displayed, just a black window that goes away quickly.
I then turned on the CPU usage in Developer Options to see if anything consistently came to the top when toggling. I saw a few apps each time Plume (Twitter), and Maildroid (email) were two of them. Both of these apps behave differently on wifi and 3G/4G (push vs. pull), so thought -maybe- it could be something with that. I uninstalled both of those, rebooted and tried again, getting the same result.
I recorded the screen when this was happening with the CPU usage displayed, and was wondering if anyone has any ideas? I don't really want to uninstall and reinstall EVERY app on my phone, so I was hoping someone may have seen this before or see something I'm missing when watching it happen.

Thanks for any input anyone can offer!

Do you check virus from your phone ?

I am also having this, seems to be due to 4.4.2 OTA, which I continue to delay as I am rooted.
Mine doens't only happen with wifi change, but also just randomly when using hangouts, keyboard stays out but hangouts min -> maxes quickly. I have tried freezing the update apps but it apparently didn't do anything as I was still asked to update earlier.

Only hangouts? I have that app disabled.in the app settings.

I can't say for sure that being on 4.4.2 fixed it, but I am on 4.4.2 now and it is not happening anymore.
I unlocked my bootloader and did the 4.4.2 SBF, unlocked and rooted. I installed probably 99% of the same apps (only ditched 1-2 that I never used anymore) and I am not having the flashing issue anymore.
Hard to tell for certain if the pending OTA was the cause, but it may have been.

WiFi problem, making phone virtually unusable

Morning all.
My Z1 is massively playing up. I keep getting a message about the WiFi not working. It pops up literally every few seconds no matter what. I don't use WiFi ever anymore and it's never turned on.
Anyone got any guesses as to what is causing it?
Hopefully I'll be shot of this crap phone today as it has so many bugs it's not even funny anymore. But should my network not let me upgrade early I'll be stuck with it another year.

wifi problem
This is an issue most likely caused by a 3rd party app.
Do you have an app called inTouch installed? If so, uninstall it. inTouch is know to cause this error message to occur.
Also, viber, Skype and other similar apps can display messages like this. Uninstall viber/skype any other 3rd party communications apps.
If this doesn't help, try to clear the cache and data for google play services. You can do this by going to settings>apps>all and finding google play services. Then press the button to clear the cache and data.
If this still doesn't work, factory reset your phone.
Hope I helped!

DarkHaxe I do believe I owe you a beer chap. It was Three In Touch that seemed to be causing the notifications. I've prevented it from posting notifications and they have stopped. Unfortunately I can't delete it as I need it at home where I have WiFi but no signal coverage.
Top man. Cheers.

Not receiving texts

Hi all,
my 4X, Miui 9.5.4.0 ROM, will not receive text messages most of the time. I can send texts OK but for the most part I cannot receive a text. I say for the most part because every now and then one seems to sneak through for some reason.
The only messaging app installed is the stock MIUI one that came with the phone. I did try a couple of other messaging apps with the same result. They have since been removed.
Any thoughts or ideas appreciated.
TIA
Greg

I can't imagine it's something wrong with MIUI? it never actually happened to me, I'd contact your carrier first, perhaps they have blocked numbers from texting you
I recommend also checking in Settings; System apps > Call settings > Blocklist to see if the phone has blocked incoming test messages from any numbers

I've just placed the SIM into another phone and it works fine, so it's not the carrier. Checked blocklist and nothing there, plus I can miss and intermittently get texts from the same person.
It's got to be a MIUI thing!

Do you notice that you lose signal a lot? It could be a faulty antenna band too, it can be replaced under warranty

No I have a strong signal, so I do not think it's that.
Just did a test:
1. Rebooted phone
2. As soon as the lockscreen appears I sent a text from my wife phone.
3. It is received.
4. Wait one minute and send another 3 texts from my wifes phone.
5. None received.
6. Reboot phone.
7. The 3 missed texts arrive as soon as the phone reboots.
8. Wait one minute and send another 3 texts from wife's phone.
9. None received.
10. Reboot phone
11. 3 missed texts arrive as soon as the phone reboots.
It has to be MIUI.

That sounds annoying... If you can, go to developer options, and enable "Show all ANR" and use the phone (especially SMS) for a while to see if the culprit is a system process failing to stay alive, and try to clear all data for that process
You should be able to find the process by going to "Installed apps" and enabling "Show system apps"
Researching more on the problem has no real conclusion at all.. Some people solved the problem by just doing a factory reset, some more gets it fixed after calling their carrier, another gets it fixed (temporarily) by just turning airplane mode on and off

I have found the problem. "Turn on MIUI optimization" in Developer Options was turned OFF. Turning it ON fixed the receiving of texts. Tried several times turning it OFF and then ON and texts stopped everytime it was OFF. Don't know what this setting does but it needs to be ON to receive texts.

That's weird! I have it off all the time, what it does is
1. Closes apps in memory prematurely, this can be bad or good, unused ram is wasted ram anyway
2. Monitor background services and disabled part of it when you're not actually using it, this killed notifications for certain apps for me, at least back in MIUI 8
There's more, but it's really trivial like UI changes it does, happy it's solved though

P20 Pro Vibrates Randomly

So, over the last few weeks I've found that my P20 Pro vibrates for no (known reason), every now and again. Usually multiple times per day.
I've tried turning it off and back on, killing the apps, checking for updates, turning notifications off on most apps.
Has anyone had a similar problem and /or has any way of diagnosing or fixing it?

I have experienced the same thing, so you're not totally alone if that helps. I haven't found the cause yet either. I suspect it might be WiFi+ vibrating when the source switches back and forth so it'll happen in stints for me.

i have the same thing and i think i might found the reason, i have some muted WhatsApp chat groups and it seems like that every now and then when i get messages in these groups my phone vibrates although i muted them . There is no notification but a short vibration.
Another thing that bothers me more is when receiving an whats app message my phone vibrates once short and after that the way i set it up in the settings...

I begin to get it after an update. hope to see a solution soon.

No
I believe I've found the cause and solution to the Huawei mate 20 pro random vibrations.
I installed a notification logger from the play store and found that it was logging notifications of repetitive image downloads completing that lined up with every buzz.
If you go into settings, apps and choose to see system apps in the menu, you can force close the download and download manager apps. If you then clear the data and cache from each, you should find the phantom notifications stop.
I haven't had one in days now, and it was all the time.
I hope this is of help.

This happens to me a lot. Its mainly due to voice recognition thinking I'm am speaking to the phone. It happens randomly when watching TV, at work on even in the train. There's no specific key work that triggers it,. It happens at random. This is my issue with the random vibration but your could be a different reason although

Mine was definitely the download manager continuously redownloading Google photos images. Force stop, clear data, clear cache of the download and download manager system apps and mine has been fine now for a week. Try it!

Had the same issue months ago. Cleaning cache and data of stock download manager app solved it for me.

Mine started doing same yesterday ?

I have the mate 20 pro, and it's just started randomly vibrating with no notification
So my phone is now starting to randomly vibrate like bursts of short vibrations that last a while, but there's no notifications or anything? I don't know how to find the "download manager" to check if it's that. I'm not sure which apps to force stop. It's really annoying though.

Do you use Textra? Happened to my wife's s8 and she just uninstalled then reinstalled Textra to make the problem go away.

I have cleared the download manager and everything else several times, but it only works for few days even hours and starts again. I'm not sure if it activities itself again after I download something, but nevertheless, this just shouldn't happen. How can I disable download manager permanently (or preferably just the vibrations, as I assume DM is there for a reason)

Had the same issue. No problem from textra, for me it was google drive. I uninstalled it, cleared cahe and data and I am now using OneDrive. I haven't experienced any random vibrations since then.

Mate 20 X had similar issue after EMUI 9.1 upgrade and turned out to be contacts sync system app constantly trying to sync contacts. Force stop and cleared data and all good now.

I have the same issue on regular mate 20 since the last software update to EMUI 9.1.0. All the suggested solutions here did not resolve the issue. If someone has more suggestions please share

I fixed it. It's a system application called "Contacts Sync" disabling it solved the issue for me.
Settings > apps > show system processes > search for Contacts Sync > disable and force close it

This didnt work for me, but i found another solution. I stopped almost all apps from autostart. except email and messangers. that immediately solved the issue and the phone boots much faster as well, nice sideeffect
You need to go into battery usage and then click on the individual app, then app launch.
I hope that helps

I just noticed this on my mate 20x on 9.1 on vibrate mode. Did your solution permanently resolve this issue or do you have to do it multiple times or after restarts?

Yes it did. I force close it and disabled it from app settings. Never came back

Notifications Issue

Is anyone having issues with their notifications not coming through, or coming in super late, or having the same notifications coming up over and over? I'm expecting all three problems, it seems to be happening with every app for me except for calls and text. I factory reset the phone but that didn't fix the issue. If I restart the phone, then all my notifications that haven't physically gone into the app to check start pouring in. No idea what could be causing the issue and it's really starting to piss me off. I have already sent my phone in for repair cause my LTE data stopped working for no reason. I don't think both issues are related as I do have LTE data after they replaced some part.
Would appreciate if anyone has any ideas.
Thanks.

I had notification delays with gmail app, fixed it by turning off battery optimization for this specific app.

Some people may have battery saver on and this may cause late notifications. Also check in settings "auto sync", under accounts. I did have some late notifications issue with Gmail app and do know battery optimization usually is the cause, but it went away in couple of days after I bought the phone.

Thank you for the suggestions. I ended up turning on high performance mode. Let's see if that helps.

How'd this work out for you? This phone is horrible for notifications for me. It constantly doesn't send them until I actually pick up my phone, then suddenly I'll get 5-10 notifications at once. I've turned off EVERY bit of power saving that I can find. I only run in high performance mode 24/7 with all adaptive battery, power optimization, auto app sleep, etc turned completely off. I've also tried disabling all power saving and sleep in the specific app pages as well. I need to be more observant, but I think this is mostly with push notifications (ex, my 2FA app for work) rather than apps with timers to check for updates occasionally. I also have an issue with my wifi disconnecting while the screen is off sometimes which is highly annoying since my home presence detection is based on my phone being on the wifi, though last time it started doing that a reboot fixed it.
Unfortunately, a search proves that this is a widespread issue. At this point I've pretty much given up on this phone and am looking to replace it as soon as I find a suitable alternative. I'm just curious if it's a Samsung issue or a Pie issue that will occur on other phones as well.

Seems to be a general issue with android. Mine have gotten better recently. In addition to turning off battery optimization for any apps I want notifications for, i have done the following:
1. Wiped cache (under settings/app/storage), then rebooted into recovery mode and wiped the cache partition.
2. Gone into the setting and made sure apps I want notifications for are allowed to run in the background (settings/apps/select app for notifications/battery).
3. Allowed to run in background when on mobile networks (settings/apps/select app/mobile data/Allow Background Data Usage.
4. Gone into messages/settings/more settings/push message/changed toggle from "Prompt" to "Always".
Hope that helps.

Thanks, I'll give some of those a try. I also got a VZW update with the May security patch among other things right after I posted that, so we'll see if that helps at all also.

It's gotten better for me. I enabled high performance mode but I had to keep going in and checking it a couple days after still even though it was enabled. Been a couple weeks now and the notifications I was missing before all seems to be coming in fine now. Time will tell though I guess lol
Are you also having trouble with apps updating? That was another problem I was having where I'd see apps needing to update, I'd start "update all" one app would download and then get stuck at 99% and it would just stay like that for about 40mins and prevent the other apps from updating. Then finally when it would finish the next one would do the same. It would literally take hours upon hours for 12 apps to update when it should only take a couple mins. That issue seems to be fixed for me now too.
