@All,

I have two OP7T devices: an HD1903 and an HD1907 (variant, converted).

Both are running the latest version of LOS 20/MindTheGapps, without any issues ... (since LOS18)

However, since updating fw to 12, HD1907 now takes considerably longer to start up than HD1903 ... 90 s vs 20 s !

Have any of you experienced this behavior? If so, do you know the reason behind it?

Edit: Revert to firmware version 11.0.9.1, then upgrade to LOS 20 (with embedded firmware) via LOS 18 recovery does not fix the HD1907's startup time.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] littlenoodles:
I think the bootup delay is built into the Android 12 firmware (as is the nasty fingerprint/brightness bug). In any case it happens on a stock device with the bootloader unlocked. For what it's worth, I unlocked the bootloader in anticipation of installing this LOS 20 ROM, but I'm not getting very warm feelings about it working any better (or even as well as) the stock OOS 12 - which, aside from the two abovementioned hassles, works pretty well.

Hello @LuK1337

Would it be possible to have this Open Webview Magisk module working in LOS? The install error says that the ROM may need a patch to make it work. With Bromite not being updated (and its webview too) I'd like to install Mulch but need Open Webview to be able to install it (see below)

Do I even need to install it? What webview implementation do recent versions of LOS incorporate?

Double-Tap to wake (Dt2w) no longer seems to work since the last version (0827).
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] PiranhaPhish:
I can report that it is working on mine.

However I can also say that the last version I upgraded to, prior to this, had the effect of disabling dt2w, but re-enabling the setting was all that was needed to restore it.

If cycling the setting doesn't work for you, then maybe there's some issue in the chain of upgrades. Perhaps install the prior version, check it there, then upgrade to this latest version.

Finally, I found the time and peace to move from stock to LineageOS 20 - and it's great. Thank you to everyone making it possible and so smooth! A few points that I was wondering and had asked about before just to encourage other doubting users.

All three cameras work out of the box using the default app (Aperture) and quality seems quite OK.

In case someone is doubting (and this being the first A/B device with a custom ROM & additional packages): Yes, it is a device with A/B partition but the updater & recovery and used additional packages (NikGApps core & ih8sn) have

zero issues

with it also when installing a new build (I started on purpose with the one of 20230813 and moved already to 20230820 for testing).

SafetyNet: Thanks to the work of Eric-Lev (ih8sn) explained in this post, I had no issue to get SafetyNet to pass (basic & CTS "Pass", evaluation "BASIC").

Potentially related to this, also no issues so far with two German banking TAN generators (usual suspects to complain ...).

Some observations:

The device is a HD1903 (also stated by OOS12) but since installing the custom ROM stating HD1901. Not sure whether this can cause any issues - none that I see so far.

After the very first boot having flashed the custom ROM, I had issues swiping from the top or bottom (basically no effect, no access to quick access menu or moving to home screen) except on the lock screen where it worked and made me think it must be a software flaw. After a reboot (and also persistent upon another factory reset), the issue was gone.

I am happy! :)
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] borisSweden:
I have a question about this phones WiFi capability. I use 2 apps to check if AX supports exists. One is DeviceInfo HW(root) and any WiFi analyser from F-droid. The apps say WiFi 6 is not enabled but us there and 5Ghz AX is used with 80Mhz.

I don't get it, is there a difference between Wifi-AC 5Ghz and Wifi-AX that supports 5Ghz? Is there a hidden Wifi-6 hardware that can't used because of binary code or a hardware lock?

I did do research before and found out that the WiFi/,BT chip on the 855 is the WCN3990, a ancient modem from the 835 era. 865 uses the wcn3991.

What is going on? I'm not gonna ask 1+forum because it's bad.

IMHO, first time I come across such a topic. I don't know the logistics of mobile, but I'd presume manufacturers don't put more expensive (production, licensing, etc.) chips in the device, just to lock them down to be less capable, only to profit less.

(Supposedly, Wi-Fi chips, cards, routers, towers in general are more capable than they really are, but are at the core level are restricted by various regulatory bodies e.g., FCC.)
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] borisSweden:
Maybe Qualcomm uses the same chip but different software. Between the 855 and 865 is wcn3990 and wcn3991. I remember Qualcomm was raving about exiting hardware supporting Wifi6 and BT5.1. The Maclaren does have BT5.1 support but I suspect its the 5G modem. Another 855 with 6 support is the Samsung Flip but that was a Broadcomm chip, not 3990.

Got the idea after watching the LTT video on expansion pack Intel chips. FYI this Qualcomm license stuff happened before, like Galileo GNSS support after everyone adopting the SD821 and QC saying its the OEM job to enable it for a fee. Your paying for a pig inside a sack.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
What I would like to add on the positive observations (while maybe not specific to OnePlus 7T but general to LineageOS): The Bluetooth media player interaction with my car (Skoda) is way better than with the stock OS - allowing e. g. selection of different apps and different items within the app via the car media player (not Android Auto!). The stock OS showed all those points but was not able to use them (either doing nothing or stating this function is not there). Same good integration, I had observed also with OnePlus 5 on a Toyota.

This is the one downside I found so far: The automatic brightness control - not being stuck as mentioned in the quoted post - is not great. Most of the time, it is way too bright and I have to tune down manually (also to save battery). I switched off also the automatic display mode control (was on as default) as mentioned there but no difference in my case. Curious whether anyone has different observation or a solution.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] nkhater:
All Oneplus devices have the same brightness issues, just turn off automatic and use manual and move on, It's the sensor source code that's used in OOS
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
OK, good to know (while I can't recall such issues with OP5). I moved already to full manual control in the mean time and this is fully sufficient indeed.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] borisSweden:
But xda_johndoe, if I wanted to test Wireless blobs from a 865 device in a 855 phone, what kind of tutorials for building LOS ROMs would I follow?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] xda_johndoe:
Another "workaround" suggested by others in the past: Settings > Display > Adaptive brightness > One shot auto-brightness [enabled].

Not perfect but for my usage (light environment), still better than going full manual.

Guides > Build for yourself might be a start, or general search for it on xda or web.

I've never built/compiled anything myself. Lack of advanced knowledge and skill.

I just assumed, those with a possession of such advanced libraries installed and running in their mind, would backport anything useful that can be done so.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] PiranhaPhish:
Oh wow! The Aug 20 update appears to have fixed the green tint and (mostly) the brightness issues on HD1907 (T-Mobile converted)!

The brightness is still left at full after using the fingerprint sensor, but the brightness still scales properly afterward and no longer gets the green tint.

Finally, this is great. This was the last nagging issue for me on this ROM. For me, nearly everything else works perfectly (no WiFi or GPS issues). I think the *only* remaining issue for me is with AoD where, when enabled, the screen doesn't respond to fingerprint unlock or double-tap-to-wake after the screen has been locked for 3 seconds.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
The double-tap-to-wake issue has been resolved latest with the September 3rd update.

Hello, I have a question, what is the super_empty.img file for?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] PiranhaPhish:
To be clear, I'm talking about the inability to use double-tap-to-wake with Always-On-Display (Ambient Display, Always On). Even with the Sep 3 update, it still doesn't work.

With this AoD setting on, 3 seconds after my phone goes to sleep, a subtle flash is visible on the ambient display after which the phone no longer responds to *any* touch events. Before the 3 seconds, d2tw still works along with the finger print unlock. But after the 3 seconds it is required to press the power button to wake it.

For some strange reason, my dt2w never broke with the recent update as others have concluded. Not sure why.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
OK, I missed the AoD point indeed. I checked and I have the AoD setting activated (but neither always nor the sensor). But d2tw works all right here.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
I noticed one minor bug: Using the zoom camera with built-in Aperture camera app, the orientation is not considered/stored when taking an image in landscape mode. I checked both with built-in Gallery app and another app. Doing the same with OpenCamera is working as expected - storing orientation.

Taking more pictures, this seems to be not limited to the zoom camera. While the GUI clearly recognizes being in landscape mode (90° turn etc.), this is not stored for some images with both normal and zoom camera. I haven't tested the wide angle camera.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] PiranhaPhish:
*edit: Disregard. This was apparently an issue with Google Play Services that happened around the same time I upgraded: [Fixed] Smart Lock Trusted devices missing from Google Pixel, Samsung

It seems the Sep 17 update has removed "Trusted Devices" from the Smart Lock settings for me. Is anybody else having that issue?

The related settings pages are there: Trusted Places and On-Body Detection.

I tried downgrading the LOS from settings but I guess that's not supported and requires a normal flash. I think it should be safe but don't want to chance it and am hoping the next update restores the functionality.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Tensha:
Hi, Thanks for the Rom.

Im tryiing this rom for daily use.

At first boot, the phone felt very hot and remained very hot until it was restarted.

Now it seems better, even though I can still feel a slight warmth during use that was not there with the stock rom.

Gallery issue: Why does the gallery save selfie images without the mirror effect even though the "Mirror front camera" option is specified in the camera settings. If I open the same photo from Google Photos, I see it correctly, but the LineageOS gallery saves it without a mirror, why?

It seems to me that the battery consumption is higher than with the stock rom. I recently tried to disable the dynamic screen refresh rate to see if it improves.

The speaker volume seems significantly lower than on the stock rom.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
Maybe consider also to deactivate the automatic brightness control (tends to be too bright = more battery consumption). A. o. addressed here and in the replies:

[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] marks7389:
Hi All,

I've had Lineage OS 20 running perfectly on my 7T since around April. However, a couple of weeks ago I updated to the 17th September nightly using the standard Updater tool, since when my battery consumption has roughly doubled - as confirmed by the daily charge percentage within AccuBattery.

Since updated to 1st October nightly but that hasn't helped.

Installed BetterBatteryStats which seems to be showing substantial wakelock activity whilst the phone is idle with the screen off. It shows a significant amount of time with the PowerManagerService wakelock active, which I understand should be the sum total of every partial wakelock, however the partial wakelocks add up to a much smaller amount.

Not really sure where to go next, other than to downgrade to the 21st May nightly which is what I had previously.

Any suggestions?

Seriously? :ROFLMAO: Thank you for explaining. I was wondering more about an emergency fix while missing extensive discussions typical for such issues.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
Not sure whether or how much of this observation is related to this ROM but I might be lucky:

Since moving from last available OxygenOS (meaning, I assume being on latest firmware) for OP7T to LineageOS (NikGApps, no other packages) according to the manual, I am observing in some locations funny "flickering" between 4G and 4G+ network. Most of the time, it will be on 4G but 4G+ popping up briefly. This occurs when trying actively to use mobile data and there seem to be only data available while being on 4G+. This is based on observation that nothing loads with 4G visible and then a burst of "new data" is noticeable while 4G+ is shown e. g. loading a website.

The above behavior occurs only since the move to LOS but I had in the same area/location before troubles with simple calls (had to even deactivate 4G sometimes).

I am using a German O2 SIM.

One of the troublesome locations is in Utrecht area (Netherlands) but it is not 100 % reproducible while seen both for NL KPN and Odido (former T-Mobile NL).

I can't recall having seen this issue in Germany. So, it might be specific to roaming (while also working in the Netherlands in other locations) but can't say for sure.

To be honest, my assumption is more an incompatibility of O2 DE and some Dutch networks / network locations since it occured before with VoLTE. But who knows ... maybe someone has an idea.

I can also say something is wrong with IMS. On Android 11, Wifi-calling always worked on flight mode. Now it doesn't work, it all depends on signal strength for GSM/UMTS/LTE.

Hi, the phones WiFi/BT combo_chip is the FastConnect6200. I wonder what the firmwares source is? Is it CodeAurora blobs or not? Becauce the chip is used by other mid and low tier Qualcomm SoC. Is the firmware for the WiFi/BT chip the same for all SoC using the FastConnect 6200?

Also would a OTA update revert the overideconfig file in efsprofiles I just modded?

One more thing, does Airplane mode keep Wifi ON? I just noticed its not ON when I switch mode but BT is enabled all the time.

Question... I've been wondering why the splash screen on boot does not display the annoying 'warning, your bootloader is unlocked" that I've always seen and expect to see with an unlocked bootloader, on this ROM LOS20.

Upon boot, the only thing that shows is the OnePluse icon in the center, and then after at least 45 seconds, proceeds directly to the LineageOS boot animation. What gives? Is this normal? Bootloader mode shows unlocked.
