General connectivity issues - Xiaomi Black Shark 3 Questions & Answers

Hey folks!
I just picked up the BS3 after being generally disappointed for most of a year with the Razer Phone 2. I got the EU version (I guess?) and have been having general issues with the wireless.
Periodically, almost the entire suite of wireless connectivity just drops. My WearOS watch (Ticwatch Pro 2020) will disconnect, and the custom watchface I use via Watchfaces disappears. Wifi usually keeps working so I may not notice the drop right away, but if I'm on my phone's cellular connection, nothing goes through even though it shows signal and LTE. In my car on my way home from work this morning I was on the phone with my captain, and the bluetooth connection to my car started cutting in and out, to the point that I had to turn bluetooth off to finish the call. There was no issue up to that point, while driving and listening to Audible.
I am suspecting/hoping it was user error in setting the device up. I backed up my RP2 to Google Drive, because I didn't want to lose my apps/data (I was mostly hoping my Swype settings and game logins would transfer over, since Swype died and I'm being a luddite, and the games require the hassle of 'transfer IDs') and have my text messages transfer over easily. I think it also possibly transferred the core device stuff like cellular and bluetooth settings as well, though am not sure.
Turning airplane mode on and off seems to 'reset' things and it'll reconnect to stuff, for a while again at least. I noticed I am somehow still getting at least some push notifications on my watch even though it shows as disconnected. I am a firefighter, on AT&T's Firstnet, so am also not sure if maybe the Firstnet bands might be being finnicky with the BS3.
Thanks ahead of time for any help and suggestions!
ETA: I also get the "Xiaomi SIM activation failed" alert every time I restart the phone, and sometimes after reboot the keyboard doesn't load. ? I get the feeling ill need to reflash again, but knowing where I went wrong first would help! Also curious if there is a stock Android ROM because this JoyUI seems a hassle, and I just don't want all the Xiaomi stuff.

No way to control Wifi connection after connection attempt !

Hi,
I have been using Wifi on my Qtek 9090 for several months already with no pb (except maybe the poor signal level).
I installed recently a VPN software to connect to my company's intranet. Works just fine. I can now access my work emails at any time from anywhere.
The only thing is that since then, when I start wifi on the unit, the check box does not get "ticked" and it gives the impression that Wifi was not started. BUT when the upper left light is blinking, the battery gets drained a lot faster and when I look at the network cards, I can see the available wifi networks. All signs of being connected.
So far I would not mind too much but I can not STOP Wifi anymore. I did not find anyway to stop it (of course, since all software apps controlling are saying that it is stopped already)...
Anyone has seen this somewhere? Any idea on how to fix this?
Thanks !
Sorry for asking again but I'm really stuck with that. I can start wifi on the unit but when started I can not stop it anymore !!! It seems that the software apps controlling wifi do not see it started and thus do not ofer the possibility to stop it.
This makes it impossible to use wifi since baterries can not afford wifi always on...
Anyone has seen this somewhere already?

Need some help, wifi doesn't work, period. Long.

Not sure how exactly to describe my problem other than my wifi has never worked on my Note 4. I got fed up with it and finally had a replacement device ordered after a 4th trip to the sprint store for service where the last tech finally agreed that the device was defective only to have the same problem with the new phone too. I love the phone and after having the Note 2 for a couple of trouble free years wanted this one to replace it but I'm lost for words right now. We have 3 Galaxy S5's and the Note 4 on the same account, under the same roof, using the same routers, tv's to connect to, etc... all s5's work flawlessly with wifi, and using Allshare on our Samsung Smart tv (which we use a lot) so I know there's no issue with any other equipment and this issue is everywhere I go, not just at home. As far as me knowing what I'm doing, well maybe I'm missing something but I've had Android phones since day one and have been rooting since the Epic 4g (no root on the Note 4) so I'd like to think that I'd catch some kind of setting here plus 4 techs have re-set, updated, double checked, and replaced the phone with no luck. Here's what it does, power the phone up and connect to wifi, no problem, visit website or watch video no problem, super fast like it should be, about a minute later blue circle loading video or load next page and get a could not connect to network or refresh page. At that time I can simply switch wifi off and the page or video will load and be fine. Switch wifi back on same thing, works like a champ for about a minute then nothing. Then there's Allshare, never had a problem with my Note 2, ever, all of our s5's work flawlessly, try to connect my Note 4 and the tv can't detect the phone and the phone can't detect the tv. It will work every so often but only for about 30 seconds and freeze then you can't connect again. One more issue I believe to be having is the gps, I ride a road bike a couple times a week and track my mileage using a bike computer app, sometimes it will track me sometimes it won't at all, and if I use the Navigation I constantly get the "lost gps signal" message. I need some help here, I'm tired of going to the Sprint Store, I just want a phone that works! That bill keeps coming every month and each time I pay it I get pissed off that my 9 year old has a better working phone than me and I have the Next Big Thing. So far its been a big disappointment!
Did you factory reset after lollipop OB7 update?
Check your Wi-Fi and GPS settings. I believe most routers won't allow address conflicts but check your router for connected devices and make sure that isn't happening. Do you restrict wireless to MAC address on your router? Maybe you need to update the trusted MAC table?
May just be a factory reset takes care of the issues. If not, compare settings with the other phones.
Still not working? Try some static IP settings and set DNS to Google. (Long press your router in Wi-Fi networks and select modify, check advanced settings and scroll. You should see the Google DNS servers dimly lit just enter the same numbers) If not, Google it.
I can't compare the s5 to the Note 4 but comparing the Epic to Note 4, Wi-Fi signal strength and speed of connection is much better on the Note 4; I see more Wi-Fi networks, too. I haven't navigated with Note 4 so I can't compare that.

Cellular data loss (radio reboot?)

Hello all,
I am currently attempting to troubleshoot/corroborate apparent issues with the mobile radio. My first device took six or seven attempts to activate, and then intermittently threw a no SIM error with what looks like a radio restart (no signal on any bands, cycle between No Service/Searching 4-5 times before reconnect.)
WiFi appears to be good, I'm only experiencing these drops while connected to LTE with no graceful fallback to 3g or even 1x. Drops are happening while stationary and in motion, frequently in areas where my signal is at least decent. The threads linked above both have users who appear to be having the same problem. Particularly strange is that there dose seem to be a location component, there are two spots in particular that seem to be more likely to cause the problem (though not every time.)
I've replaced the device once already in an attempt to resolve this, and while I initially thought that the issue was resolved, I did manage to catch another drop yesterday after running tests forcing the device in to 3g-only operation (the device performed just fine before, during, and for a few minutes directly after these tests.) Of note, I haven't managed to catch a 'No SIM' message on this replacement phone. I have been running an app to notify me of signal loss today, and of course it seems to be behaving now.
If you've experienced any similar issues, please reply and let me know if you've had luck resolving.
Yep this is what is happening allright.
I have two htc one M7s. My main phones.
Last evening, in a very strange shift from her norm, my woman asked to use MY phone to cruise the net.
Ok so she goes on and fifteen minutes later I get the phone back.
Suddenly, in the middle of refreshing a twitter or facebook, THE WI FI CONNECTION GOES DOWN.
I cant get the thing to reset after shutting it off. I have to go to the ROUTER , turn it off then on.
Five minutes later after ROUTER reboot, it is working again.
It is just the beginning of our story. I have a second phone also same make and model. It is midnight now, some four hours later, and as usual I turn off router before sleep.
I wake up, unplug other phone (not the one from last night) and, swap out the sim card to it (was in phone durring Wi Fi problem).
Now, I switch on the phone, and it comes up with LTE cuz Im on mobile. Then I get the normal "ok" from phone message (system communicating with mobile).
Heres where it gets strange. I get the 3G on top bar. Ok this NEVER happens.
One minute later it says LTE again.
Wtf is happening.
Not mentioning in this story little invisible forces kicked my left leg open as I was waking up. Angry *****es over Hillary.
Same LTE issue here. Just contacted Google Support and rebooted to safe mode. Let see if I have the same problem again tomorrow

I've got a Black 32GB XL on Verizon (Verizon Model) and never have this problem. Any tips on reproducing it? I'd love to help test and see what I can come up with. Only time my phone says no-sim is for like 5ish seconds after boot. And I've only once seen the phone fall to 3g in an area with known strong LTE. My previous note 7 fell off LTE pretty often. Specially when jumping between towers. But my PXL rarely (Once) does.
This has been happening to me on my pixel xl 128gb since the day I got it. I reported it to Verizon and to google. Google said bad sim. Verizon replaced my sim and it didn't change a thing. I can usually get it to reconnect if I toggle cellular data on and off. Please let me know if anyone finds a solution.
This is known as hollow bar. And it happens to certain Nougat phones in certain areas.

Verizon Lumia 735 on T-Mobile - bad signal / no LTE after 10.0.14393.1593 update

So tantalizingly close to full functionality of Verizon Lumia 735 on T-Mobile network, but after a blissful full day of trouble-free operation, back to phone not connecting to LTE, with connection to lower-speed signal cycling on and off.
Timeline:
On July 23rd, had phone working well after upgrade from WP8.1 to 10.0.14393.1480. While travelling in Canada (home service is in US) phone continued to work well. Until I connected to hotel WiFi on 8/8, and - thank you automatic updates, and why can't I find a way to make hotel WiFi be seen as a metered connection?? - received an update to 1593. But that update didn't successfully complete due to me not being connected to WiFi when system restarted later in the day. Phone stopped working reliably at this point.
At home: fresh install of 8.1 via Windows Device Recovery Tool - phone functioned well, picking up LTE wherever present. Ran that for a few days without problems.
Upgrade (via regular channel - upgrade advisor app, phone update settings panel). After all updates successfully completed, phone was again running 10.0.14393.1593. Bad behavior immediately after 1593 update, but one more power off/on restored normal operation. I had a full day of excellent operation with this setup - in fact, stronger / more consistent LTE than I had been getting with 8.1.
...and then... nothing. Phone just stopped picking up LTE, is mostly without signal, and no amount of power cycling or soft resets kicks things back in line.
I've tried:
Added MMS APN as I had done in the past here. Didn't expect that to have an effect, and it didn't. But I had that change in place last time my phone was working, so what the heck.
Showed and then selected "4G only" as highest connection speed in SIM settings. (To make option available, used Interop Tools to add registry key HKLM\Software\Microsoft\Cellular\MVSettings\IMSISpecific\Default\CellUX\HideHighestSpeed4GOnly = dword:0). With this setting in place, network search shows multiple LTE networks available. But selecting mine (T-Mobile LTE) still resulted in SIM settings showing "no network found" for active network.
Tried to get more detailed information via Field Test (enabled ##3282# as per here, for instance. Sadly, this appears to not be a functional option for my phone. Field test launches and gives me the "do not change any values..." warning, but after I click accept, it shows nothing other than the "field test" text at the top of the screen.)
I have only guesses as to why my phone went back to crap functionality after things went swimmingly for a day: background restore of earlier backup? Silent update of one or more Windows components a day after 1593 update was completed? Attempted silent update failed? When bad behavior set in yesterday, it was a few hours after I connected to WiFi - possibly relevant. Running Pasquale Pignataro's Device Diagnostics Hub always shows "Backup Assistant Plus" as one of the processes currently running. I'm guessing this is the non-functional Verizon thing I can't delete nor configure nor run from the control panel; but since it's a Verizon thing, it could possibly be messing with my off-network bliss? Or there is a Microsoft app/agent with the same name and it had a hand in my day-after-fix problems?
Wish my question could be more focused, but that's all I've got. Hoping some of you might have an idea of where I can start digging.
After hard reset, and turning off automatic app updates, phone did pick up LTE perfectly with 10.0.14393.1593 installed, and again worked for about a day before tanking. On the bright side, the loss of functionality isn't permanent, (though it's unpredictable and finicky). Basically: Once LTE is connected properly in one location, I have a very good chance of continuing to get LTE wherever I go. However, at any point, if/when I lose LTE signal, the phone can fail to see it for reconnection - it gets stuck cycling through none/2G/3G/none... for phone signal. I've had some luck getting it back into a good state with a soft reset followed by cycling the power on/off one or more times. Sometimes that puts things right for a full day or more, but sometimes (like just now), I get back into the bad state after a short time of having LTE. Might be tied to making a phone call.
This screams software issue to me, and my gut feeling is that it's Verizon-specific software that's likely to blame. I've so far seen and ignored updates for Verizon's backup assistant, and one other that's simply "name not available". Is there a known way to uninstall the Verizon apps like backup assistant? I haven't been able to find one with my searches. Happy to muck around in the registry, etc. as needed.
Wow, you know my pain. I recently (2 days ago) jumped from Verizon to T-Mobile (job related) and have the exact same problem. Go figure... Anyway, hoping someone may have had some luck looking into this, but I am guessing not. fingers crossed. I also have the Alcatel Idol 4S Windows 10 shipping, but hoped I could keep this one kicking.
Thanks for any help.

Xiaomi Mi 10 LTE - Hotspot issues

Hey guys,
I am having issues with my Xiaomi Mi 10 LTE, where i have been using my hotspot due to the company wifi being down for a whole week and having a lot of issues. Currently i am only able to use my hotspot if i use no security, as with the WPA-2 security it fails to connect to internet or just outright fails to initialise the connection. If i do connect with no security, it fails if i disconnect or if i lock my tablet for a short time and refuses to connect again. I have found a workaround where i can add security and a password, then leave it to initialize the connection... i can't connect to it even with the correct password, but if i change the hotspot to have no security again it will connect fine. I have tried resetting my connection settings and this fixes it for an hour or so and then stops working. I have tried changing from 2.4g to 5g and back, this doesn't work. If i change the sim card slot it works for an hour and then breaks again. I can use the fix of adding a password and removing it but it is generally a massive pain in the a**.
Does anyone have anything they have tried that works as a perminent fix?
Thanks in advance!
Just to add, i am connecting to the hotspot with my Samsung Tab S7+ which has had no isses with other wifi connections and worked on my S7 Phone so i am sure it is the new phone. I have had it a few months but never used the hotspot until now.
I've been having quite a similar issue, and this is the second time I get it on the same model! I guess this is a bug or an hardware problem related to the model. The only thing I noticed working, and it's not a security issue in my opinion, is the position where you keep it! try to holding it in your hand at different inclination , until you find the right position. the one I'm using right now works better when lying on a table, the previous one worked better in a standing, lightly tilted position, as you can see in th eimage
That is insane! I'll have to try a few things and I'll get back with results. Normally my phone is lying down on a table but I'll check a few positions. I have found that screen mirroring seems to have the same effect... as in it doesn't really work. I don't know if it is just data out when the issue arises as I don't have any problems downloading or streaming etc.
