[BV Crown] Audio profile settings reset randomly - Android Q&A, Help & Troubleshooting

Hi guys,
I own a Blackview Crown with the latest SW released (20141015).
I noticed that randomly during the day the audio profiles and the data settings for the dual SIM management are reset to the default values.
For example: I set "screen lock sound" and "vibrate on touch" to OFF and they are set to ON automatically by the system.
In contemporary the bug affects also the data connection settings on the DUAL SIM management menu... it is switched from one SIM card to the other one (and this is the most annoying problem...).
Do you know whether this can be a known problem? Or maybe this is an Android bug?
I already tried to write to Blackview.hk but received no answers so far...
Thanks a lot for your help!!
PS you know whether there is a LOG that can be activated to understand what is happening? this issue does not happen during system reboot... it happens really randomly, every 1-2 days

I found that the settings reset is caused by the Android "POWER SAVING MANAGEMENT" function.
When the "POWER SAVING MANAGEMENT" function is enabled many services are stopped to save power (like data connection or ringtone volume for example). When the "POWER SAVING MANAGEMENT" function is disabled, the settings are set at the default values (such as "high precision" GPS or "vibrate on touch"). The customized settings are lost.
I do not know whether this is a Crown-related issue or it's common to all the Android 4.4.2 users.

Wi-Fi performance, sleep mode, VOIP, notifications

I've seen a few reports that people do not receive new mail notifications when the screen is off. The wifi implementation by HTC is horribly broken. You'd think that enabling the option "Always keep wifi ON during sleep" would do just that, but it doesn't. Disabling Power Save mode doesn't help either.
What I found to help is enabling the option "Best Wi-Fi Performance" under the Wi-Fi Advanced settings. Not sure what the battery impact is though.
I started looking into it because I was having VOIP problems when using CSipSimple. I noticed that every time I put my phone to my ear the screen would turn off (the proximity sensor) and the call would become really choppy - it would not get disconnected, just very choppy. Then I enabled the advanced CSipSimple option to keep the screen on during a call and that fixed the problem. Then I started looking if there was another setting that I could use while keeping the screen off. It seems "Best Wi-Fi Performance" does it, even if Power Save mode is ON.
So, if you want notifications to come in while the screen is off, try this option.
For VOIP calls, it's probably easier to just configure the VOIP client (if it supports it) to keep the screen on during the call, unless you are on the phone for hours and it doesn't make sense to drain the battery because of the screen. Then again, turning on the option above is a better choice. Now it would be nice for these VOIP/SIP clients to have an option to toggle the HTC setting on during a call and flip it back to its previous state at the end of the call.

Tasker profile becomes inactive after phone is idle for 10 minutes

Hi all,
I have an AT&T Samsung Note 3 SM-N900A running Android 4.3 (baseband version N900AUCUBMJ5, kernel v3.4.0-1625098). I rooted it using Kingo, installed Tasker (with Secure Settings plugin), and created 2 profiles: one with a 'Home' location context, and one with a 'Work' location context. In the 'Location Edit' map screen for each, I set a pinned location w/ a radius of 200m. I also de-select 'GPS' (leaving only 'NET'), since I don't want GPS enabled all the time (to extend battery life). I confirm that these work when I'm actively using the phone.. the profile becomes active when I'm at the specified location (as expected). I know it's active because it's displayed in the Notification Panel (and it's also shown in green in the Tasker profiles list).
The issue I'm having is that after ~10 minutes of idle time (i.e. when the display is off and I'm not using the phone), I find that the profile is no longer active when I turn the display back on and start using the phone again. I confirmed that this *doesn't* happen after 1 minute, 2 minutes, nor 5 minutes… only > 10. I also confirmed that it happens for both profiles consistently. However, as soon as I start Tasker again from the Apps Drawer (or from Recent Apps screen), the profile is immediately activated again, and my Enter task is re-run.
I enabled the run log in Tasker prefs, but it basically shows a clean activation of the profile (with no warnings or anything that looks weird to me).
I know there's a 10-minute timeout in the Display Off Monitoring prefs, but that doesn't seem to be related to my issue. I tried reducing the All Checks Seconds from 600 to 90, rebooted the phone, and it still took ~10 minutes before the profile would become inactive after the phone being idle.
Any thoughts as to what the culprit might be? Are there any system logs I can look at that might shed some light here? I'm new to Android, and this seemed like the place to ask..
Thanks.
Ok, not solved..
Alright, bumping this, as the problem is back again after some time.
Has anyone ever seen Tasker exhibit the behavior I described? Again, I start the phone and Tasker profile is active, let the phone go idle for >10 minutes, the profile is no longer active and I need to restart Tasker manually to make it active again.
Still trying to figure out what logs are best to look at..

[Q] Android 4.4.2, the security option "verify apps" keeps toggling itself on

[Q] Android 4.4.2, the security option "verify apps" keeps toggling itself on
I don't like a scan periodically scanning my apps in the background, so I wanted to turn it off, but even after toggling it off (in the main security page in the tablet's menu), it ends up toggling itself back on a few hours later without my consent. Is that a common issue?
I went on the google settings page as well and unticked the two options to verify apps and send analysis info, and the funny thing is that merely accessing that page without changing the settings (and when they are already unticked) will automatically toggle the "verify apps" setting in the main security menu on the tablet. Although even if I dont visit that page, leave them unticked there and have it unticked in the main security menu, it will still toggle itself back on a few hours later in the main security menu.
What's going on here? Is google pushing that option to be on at all time to scan your apps regardless of users choice?
Has no one heard or experienced this issue?
To the people reading this who are using Kitkat, does your "verify apps" in the general menu remains unticked for extended periods of time without ticking itself back on? If so, do you have the latest versions of google playstore and google services? (can you even use old versions of those anyway? mine seem to auto update despite me having auto update disabled in the play store)
Anyone has any idea what is causing my issue and how I could solve it?
I just noticed this happening to me. It seems that if I uncheck it, then run the play store app, "verify apps" is checked on again. I don't know how to keep it off.

Automatic wake up upon message reception

Hello, is it possible automatically wake up the stratos upon reception of a message? I want directly read it instead of going into menu and select it...
Not, yet... But a (poor) workaround it to active the "turn on on wrist movement", that can be enabled only at certain times, in Settings.

Activate accessibility option and secure start at the same time

Hi all,
apparently this seems to be a known bug (feature) of the S9, at least I found several reports on different forums, however without any solution so far.
The problem: It is not possible to activate both, the accessibility option for an app (e.g. for Nova Launcher, Tasker or BixBye) and the secure start / secure boot option (official name might be different - I'm talking about the option that requires you to enter your PIN / passphrase before your phone boots).
Whenever I try to enable one of the accessibility options, secure start is switched off.
Is there any workaround for that?
Thanks and cheers!

/edit: I forgot to mention that I never experienced this problem on my S7.
On my AT&T S7 Edge, and my AT&T S9+, I just go into the Security Settings and turn Secure Startup back on. It warns that the accessibility services won't be available until the phone fully boots.
