I have been using PA for a couple of weeks. The ROM is really great. Many thanks for the efforts devs put into it!

However, there are two issues I would like to report:

1. There is a problem with the drivers when plugging the phone into a Windows 10 PC. I have several PCs running Windows 10 and none could recognise the phone. However, when I plugged it into a Windows 7 PC at my work, the phone was immediately recognised. Luckily, no such issue with Windows 10 appears when the phone is in fastboot or fastbootd mode. Likewise, no such issue arises when the phone is plugged into Mac or Linux PC. I tried installing OnePlus Windows drivers, changing cables, ports, etc. Nothing worked. The problem arises also in Pixel Experience ROM but not in the Stock ROM.

2. The bigger issue is that after a while the phone behaves as if it is loosing connection with the SIM cards or as if the connection is jittery. The mobile data icon stats appearing and disappearing. That makes the phone rather hot. I didn't encounter this issue on Stock ROM or on Pixel Experience. This problem makes the phone rather unusable.

Once again, many thanks for this, otherwise, great ROM. I hope you will be able to sort out these issues. Keep up with the good work!

I use minimal adb & fastboot always
I mean when you are doing the fastboot commands, are you doing them from a recovery like lineage 18.1 recovery in fastbootd, or from the regular fastboot you get to from typing 'adb reboot bootloader' ? I used fastbootd that you can get to from typing 'abd reboot fastboot' ('fastboot reboot fastboot' if you are in the regular fastboot already)

    We are very excited to announce the release of Paranoid Android Quartz, based on Android 10.

    On the first launch, you’ll notice a clean setup with a beautiful wallpaper from Hampus Olsson, who teamed up with us again to create several beautiful pieces of artwork. Hampus is a multi-disciplinary artist whose design stands for itself and we’re glad to have him onboard. We also added further UI touches that we believe enhance the overall user experience. You can find all of the Paranoid Android wallpapers and many more in the Abstruct app, included in our builds.

    Our builds are based on the Code Aurora Forum Android base, which is optimized for Qualcomm platforms and has a higher degree of performance, battery life, and functionality compared to the Android Open Source Project platform. The Paranoid Android team and contributors are focusing on squashing existing bugs, and implementing and improving features, performance, and stability. We are dedicated to providing a user experience with the stability that you can expect from stock ROMs with best-in-class performance and features to help you get the most out of your device.

    Device-specific issues

    Will it have a bad side effect on the device? Like the display, battery, etc.. looks like the phone would go on high brightness for a sec then puffffff...

    If it did , im sure we would have felt something by now .
    Imagine this, as a user you see the flicker 400-500 times a day depending upon the time to unlock.
    A developer testing these cases of flicker might be seeing more than ten times that amount for testing the cause (speaking from experience) . I have not felt any signs of wear and tear to the display even in terms of colors or quality .
    So it's perfectly fine .

    And as you say , the device goes on high Brightness. That depends on the way the rom works .some use the dim layer to read the fingerprint . Some use HBM( high Brightness mode)
    Both have their pros and cons
    The dim layer advantage is that it doesn't make the screen bright during authentication but it causes an ugly smudge of colors to the screen on low brightness
    The HBM mode on the other hand does not apply any layer onto the screen but brightens it up instead and shows a steady flow of light increase . This looks better but is very bad UX because of the change in brightness
    Can anyone confirm if the fingerprint screen flicker is present in this rom? or is it fixed?

    You have to understand that screen flickering is the way in display Fingerprint works on custom roms. When a fingerprint is detected , the screen lights up to read the print and dim layer is applied on the screen causing it to flicker for a second . This can be avoided by lighting up only a part of the screen which is the fingerprint part ( which custom rom developers may not be able to do) . Hence, the whole screen lights up while authentication. Unless somebody finds a way of lighting up only parts of the screen which need to be illuminated , the flicker will always exists .
    The only solution roms use now is to reduce the amount of time the dim layer is applied so as to get a minimum response time for the fingerprint to be read and the device to be unlocked.
    hope that makes sense .
