Bv9900 some Bugs? - Blackview S8 Questions & Answers

Hello there,
I've bought few dass ago a Blackview BV9900.
Now I had a few questions:
- I cannot find an Option to activate the fingerprint unlock settings
- I installed some Tools with Accessibility Services. (tasker)
- All widgets are not started after reboot.
After a reboot all setting are deactivated.
Is this a Bug? How can I solve this Problems?
Kind regards
Chris

Do you have root?
If yes, I think you can fix the problem with non-starting widgets.
I have a BV9900 Pro and I could fix that with root: https://github.com/do1fmd/BV9900Pro-optimization/blob/main/bugfixes.md

[MK16i]SE Xperia Pro Ultima v1.1; Google Play crashes

Hello, I have a problem with running Google Play after flashing the phone with Xperia Pro Ultima v1.1 kernel and rom. The application turns on, I have logged in fine, I can see the main menu and browse, but when I try to open a game menu it crashes and it shows a message that I have to force kill (com.android.vending process).
I have Sony Ericsson Xperia Pro MK16i
Does anybody know how might I solve this? Thank you in advance
This is a known issue due to a wrong NFC file included (mk16i doesn't use NFC) in android
you need to remove a file by adb or with a root explorer.
the file is:
/system/etc/permissions/android.hardware.nfc.xml
reboot, and everything should be just find !

Thanks fixed my problem
another problem
Thank you very much for your help, it worked for me too.
But now I have another problem - when I want to send an MMS (press the add picture, go to gallery, tap the pic I want to add - application Messages crashed).
Can your wizardry help with that problem?

[Q]

Hi,
I new to the whole rooting scene so please bear with me.
I unlocked the bootloader and rooted my phone (using twrp and SuperSU) and installed LMT Launcher v2.0 RC5.
Setting it up was easy, however when I use it to launch an app nothing happens.
Well, only the wifi and bluetooth toggle actions actually work.
But setting a Pie Item to trigger an arbitrary app - this does not work (by work, I mean nothing happens when you select that pie item)
any help appreciated.
thanks,
KS

[Q] Lollipop (LRX210) - Cannot Install .apk from Storage. Any ideas?

***SOLVED***
I was using Lux Auto Brightness (https://play.google.com/store/apps/details?id=com.vito.lux&hl=en). This thread pointed me in the right direction (http://forums.androidcentral.com/sa...nt-click-install-when-installing-sd-card.html) and I uninstalled the app and I could install apps from storage again.
***SOLVED***
I have encountered a problem with Lollipop - I cannot install backed up apps from storage. The install button is simply inactive.
So, I reinstalled 5.0 factory image and it seemed to fix the problem. BUT, now it doesn't work again.
Anybody got any ideas about what is going on here?
Thanks in advance:good:
Edit: could it have something to do with a locked bootloader? Didn't have that problem with kitkat
Wow, must just be me then...
Back to the drawing board...
Wow, same thing is happening to me too. Can't believe it's due to a brightness app, doesn't seem to be much of a link between the two.

Works with alternative screen filter enabled from advanced settings
Developer of Lux here. This is fixed in the update rolling out today.
Thank you
That trick worked - I emailed the Lux developer and there should be an update coming out today!
* update
If you simply force Lux to close, then you can install apps and then just open the app again.

Android 11 - "default" Share Files does no longer work :(

Hi there,
since i've updated my Poco X3 to Android 11 the "Share" Feature does no longer work for ALL Apps that don't have it's "own" Share Feature...
Tested and does not work with:
Nova Launcher's Settings Backup
Adobe Acrobat Reader
Simple Gallery
and any other apps that does not have it's own "Share-Feature" and use the Mi Share instead...
Apps that work (because of it's own share feature):
Solid Explorer
Mi Gallery
Anyone else also got this Bug and maybe got a Solution?
Btw...
I've already done a Factory Reset and just installed Nova Launcher and Whatsapp to test it -> Share failed...
It is VERY annoying -.-
Thanks in advance!
How can it be no one else got this problem and i stuck at this Problem also after a full wipe and factory reset?! Oo
(deleted)
Hmm...
It seems this error occurs if the dumb MIUI Optimization is Disabled on Android 11 -.-
Also Whatsapp PDF's no longer openable if MIUI Optimization is disabled...
Time for Custom Rom it seems ^^

Question Notification problem on Xiaoxin Pad Pro 2021 [TB-J716F]

Hi everyone, I am a long-time user of the forum who recently purchased this tablet. It was delivered to me with fake global rom and I managed following the guides on the forum to flash the CN rom and block the bootloader. In doing so I managed to enable ota updates and certified L1, but now I have two problems, and specifically in this thread I will submit one that in my opinion is the worst: notifications problems. I tried to turn off battery optimization for the apps I was interested in receiving notifications, but despite this the notifications still do not arrive in any way, have you also had this problem? Is there anyone who by chance has solved it and in case knows how to help me? Thank you in advance for your support
You need to look for an app called security or security center. Within there you'll find an option to whitelist the apps you use regularly.
Sadly my tab suffers from the same bug described here
ZUI 13 Lenovo Security Center Problem Crashes?
Hi all, EDIT - I am reading reports this is also occurring on any Lenovo XiaoXin Pad Pro with the ZUI 13 update (perhaps it's the secondary update that does it?) not just the 12.6 inch version. I've just upgraded my tablet from a 2021 XiaoXin...
forum.xda-developers.com
So idk how to fix the issue
There is no fix yet as far as I am aware. They need to release an OTA. Its been an issue for a while though! What a joke the chinese software is!

Yeah sadly i think i have a newer version of the app and i can't install it , i tried also to uninstall with ADB command but it says failed not installed for user 0 , idk how to solve it
Also you can't disable it as the app controls permissions.
Do you know how to extract an app? When my XiaoXin Pad Pro 12.6 arrives late next week (hopefully) I could try and extract the latest version as I belive they've fixed it via an OTA.
i created a backup of the faulty app with es file explorer, but even trying to reinstall the one that is the same version gives me an error, i tried downloading app ops as someone suggested on the forum, but i have no idea how to set the apps i need.
The software on this tablet is a piece of crap, I'm regretting having locked the bootloader, at that point I should have flashed the twrp and the GSI.
if anyone else has any idea how to fix it i'm open to any suggestion and @mardon85 thank you for your help, i hope with your apk the problem can be solved.
I finally managed to uninstall the application using the ADB command " adb shell pm uninstall --user 0 com.zui.safecenter " but even in this case I can't install the working version of the apk (probably because the uninstall only affects my user and not the whole tablet, which would require the root).
also trying to install the older and working apk from the ADB terminal gives me error [INSTALL_FAILED_INVALID_APK: Package com.zui.safecenter is a persistent app. Persistent apps are not updateable.] even trying to ignore the version of the app
I'd say that at the moment I'm keeping it uninstalled while waiting for some good soul to give me some advice on how to proceed to solve the problem
I update you for those who may have the same problem. With the latest update the security app works smoothly, however the problem of notifications persists. Even disabling battery optimization for selected apps, whitelisting them for auto-start, and enabling all notifications within the app whenever I close the application from the task manager, notifications stop coming. This happens even when I simply closed the application and I continue to use the tablet for other operations (it is therefore not a problem related to the disconnection of the wifi or the standby of the device). I have no idea how to fix it, I tried everything (including some settings in the developer mode). So if anyone has any other suggestions I'm happy to try it
I have found that disabling the night mode in power settings, keeps my apps from getting closed even though I had the apps set for no battery optimization, and whitelist.
Do all Users on 13.1.555 suffer fromm the notification Bug like me?
Does a factory reset help?
