Hello @expressluke ,

I am having trouble watching DRM protected content after installing this rom.

The app works well on stock rom but after installing this rom, when I tried watching with the app, I get this error:

After some digging around I found some solution to the problem.
"Inside the /system/lib/ or the /system/vendor/lib/ partition there is a file stored by the name of liboemcrypto.so. The aforementioned apps make use of this file to play the DRM protected contents"

To solve the problem one can use rename/delete the file. This solution is not recommended.
Recommended solution is to use Magisk to install a module named liboemcrypto disabler .

Hello, first of all I congratulate you on your rom.

I have been in use for a while and if it is true that it was necessary to add, such as:



1. When you put the unlock pin or password when unlocking the equipment, do not accept (I solved this with Xposed + GravityBox)

2. The sound with the AudioFX application is disastrous, if I recommend putting Viper4AndrodFx from Magisk

3. When taking screenshots, the system sometimes gets stuck and does not save the edited screenshot.

(If or if I recommend it, to other users install the gapps, to replace the Aosp applications for a better experience, phone, messages, gallery, etc.)

And another thing that does not seem logical to me is that the Android System application is always consuming a couple of kB / s always (I have commented on this by the official group of telegrams and now there are also many people with the same problem), I attach a screenshot, to which it is due; What is download, what is upload? (I also removed all background apps, account syncs, etc. and the Android system continues to consume data.) This can be inconvenient for those who are on a reduced data plan and this app is consuming their plan.

I update

For those who have high Internet consumption on Android system, I have found the culprit for that consumption. I don't know why, the Google services framework constantly requests

ota-cache1.googlezip.net and another ota.googlezip.com

As you can see, I have used the app (PCAPdroid) to capture the traffic and in less than 30 seconds, it detects 361 requests making a consumption of 3.1MB (if it is obvious you can reach 500mb per day) from Google's Services Framework. At the moment I have added the aforementioned hots to the AdAway app (Since I use it to block advertising, then cancel those requests to those two hots)

    OP: Why release a phone rom where in call audio is not working!!! if its no longer functioning as a basic phone then please don't put the rom out until that at least is working, thanks :)
    This is now working in the new build and is now deemed stable, Actually if you read the OP page at the time, it was not intended as a build for daily use and for testing only, clearly written in red text. Thank you in advance for understanding.

    Just a little friendly reminder about forum etiquette, politeness and respect for each other as per XDA Rule 2.3:

    2.3 Flaming / Lack of respect: XDA is about sharing and this does not involve virtual yelling (flaming) or rudeness. Flaming or posting with a lack of respect is unacceptable. Treat new members in the manner in which you would like to have been treated when you were a new member. When dealing with any member, provide them with guidance, advice and instructions when you can, showing them respect and courtesy. Never post in a demanding, argumentative, disrespectful or self-righteous manner.

    Also, while asking for updates and ETA's is not "formally" against XDA rules, it is indeed not welcome as you will see by my explanation here.

    Now please let us return to "polite" on topic discussion, and keep the disagreements relegated to PM's so as the "Old Badger" doesn't have to return. Thank you.

    -Cheers: Badger50
