No, just a custom android device doing a development on.

"kiosk mode" is only something I've read about with Android, and that is either to do with prison issue tablets, like the Jpays, or a device that is used for a dedicated purpose, like for a sales counter or a tour guide device.

I'm not a dev of course, but I think if want someone to help you debug your project, maybe you need to post your code, and/or what the exact hardware is you're working on?

Yes

I created a channel for your app. Good luck!!

That's running 4.4.2 Kitkat which means it's old and slow now. Even if you installed a new ROM (if you can even find one) it probably couldn't handle some of today's apps.

Ocnbrze is spot on. Get a new tablet. You're wasting time with an outdated tablet.

When I first heard about the "onTaskRemoved" event, I thought it was some kind of party event.

keep us posted if you do gain root......though i do not know why you want to root. there is no dev community for the phone. no devs=no custom recovery, no custom roms=no fun

Oh U KNW Why I/We wanna root!

I use an LG V50 ThinQ (Android 10), and I'm also having the same issue with calendar notification sounds not working while the screen is locked.

If it is a "device specific problem" then I suggest that there's more than one device affected.

Calendar reminders should work regardless of wifi connection state.

No idea, because I don't know what a "true MT" is.

I guess it also may be related to the LTE/4G and 3G data frequency bands the phone is capable of receiving, and those of your carrier or network.
It's not a bad phone, despite your Freudian slip if you are in the UK (It's a Doogee N20) but there were better phones even for that money or less. You were possibly suckered by Amazon or other site in a quick search.

Depending on the world region you bought it, you can compare the 4G bands on the phone with those your carrier uses.A quick browse yesterday seemed to show a limited number of bands on that phone, but I may be wrong.

I only use my phone, and a Mifi dongle with a sim card, to have home wifi. You say it's been OK previously for you, and where I am in the UK most unlimited data plans allow unlimited tethering as well.

My activity is getting restarted, to avoid this I have added the possible configuration changes in my Android manifest still activity getting restarted. The android manifest as below
<activity android:configChanges="density|touchscreen|mcc|mnc|orientation|uiMode|screenLayout|screenSize|smallestScreenSize|layoutDirection|locale|fontScale|keyboard|keyboardHidden|navigation" android:name="org.app.Activity" android:label="MyApp" android:screenOrientation="landscape" android:launchMode="singleTop" android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen">

I have get the configuration at runtime and logged in Log file, The older configuration as follows

{1.0 ?mcc?mnc [en_IN] ldltr sw800dp w1280dp h728dp 160dpi xlrg land finger qwerty/v/v -nav/h winConfig={ mBounds=Rect(0, 0 - 1280, 800) mAppBounds=Rect(0, 0 - 1280, 752) mWindowingMode=fullscreen mDisplayWindowingMode=fullscreen mActivityType=standard mAlwaysOnTop=undefined mRotation=ROTATION_90} s.5}

And the changed configuration as below

{1.0 ?mcc?mnc [en_IN] ldltr sw800dp w1280dp h728dp 160dpi xlrg land finger qwerty/v/v dpad/v winConfig={ mBounds=Rect(0, 0 - 1280, 800) mAppBounds=Rect(0, 0 - 1280, 752) mWindowingMode=fullscreen mDisplayWindowingMode=fullscreen mActivityType=standard mAlwaysOnTop=undefined mRotation=ROTATION_90} s.7}

Please could you tell me what is this s.5 to s.7 change stands for?

Thanks for the reply - but the main problem is that we don't know the pattern to get in. I've managed to get around the broken screen issue by using a HDMI/USB adapterto plug it into an exrternal monitor and mouse, but without the pattern, I just can't access the data...

Thanks for the idea though.

This is a big issue with your phone. You can complain about your phone in an authorized service center and change it.

Well, I may have found it. I don't mind weather alerts coming in; it's that horribly screechy alert sound I object to. I found the text of the weather alert in my text messages which indicates to me it was a text. I didn't know text messages would do that horrible sound that would wake the dead.

I had TMobile disable text messaging on my line for ten years or more and recently changed my rate plan and I guess they turned texting back on when they did it. I also found about fifty other BS messages in there, too.

Just another reason to again to disable texting. I think I'll call TMobile and tell them again to disable texting on my line.

Regarding the audio interface issue, your Galaxy J7 (2016) apparently has a microUSB port and supports OTG so that port does allow for charging and data transfer, but it might not necessarily also support audio in/audio out too. If it was a USB Type-C port than yes, that has additional pins and with more functionality than microUSB.

As for data transfers, try connecting your phone directly to the other device, bypassing that USB hub.

French is no good for me. I want an English to Mongolian(not Cyrillic) translator app.

Back up anything important and try a factory reset.

If you have the option in recovery mode, try wiping the system cache (just the cache, not cache+data, not factory reset). That was removed from most phones a while ago, but I'm hoping that a phone I've never heard of might still have a useful legacy feature like that. There's a small chance that that might fix it, in which case you are spared a reset. But otherwise my best guess is that you've got some corrupt data somewhere that's messing up the display drivers, and I doubt I'd be able to track down precisely what (and if it's system data I might not be able to remove it anyway without root), in which case a reset will be needed.

The worst case is that the actual system software has been corrupted, in which case a reset won't help either (in that case either a reflash would be needed or, if the storage itself is damaged, there would be nothing you could do). But I think there's a good chance of a reset fixing it. From what you describe it's clearly a problem with the android system rather than the hardware, since the splash screen and boot animation work (which all come up before the Android system takes over).

Be sure to get onto the PlayStore, and turn off auto-update.

Otherwise Google will update everything again, forcing you to start all over.

(Ask me how I know...)
