Hi @adazem009 , I think I might found some bug.

1. The status bar has a black box around it on the upper part when in portrait mode like the screenshot I attached below.

View attachment 5335283

2. Ramdomly, the edit panel in the notification bar will not show up anything. Also, the nav bar probably glitch out with it too.

View attachment 5335287

And I have a bit of a suggestion:

1. Can you like make a setting we can make the speaker a bit louder or such? I feel like the speaker is a bit smaller than on stock rom with Dobly, speacially when use the Volume Leveler in Dobly.

2. The dark mode switch should be in Display setting so it more easier to find, it took me 15 mins yesterday to found that. :D

Thank you so much for reading and please answer me. And thank you for making and maintaining this great ROM.

Edit: I also have the problem with green thumbnail, but only video got that green thumbnail, photo still normal, and it affect all apps.
[Thinkpad Tablet Android Development] ZONTAC:
For louder speaker you should try Viper4android ( ainur narsil makes sounds morere precise with viper4android)

Viper4android also works in fm radio.
[Thinkpad Tablet Android Development] XAedgeS:
My package installer often went crazy and not really work, either crash or stuck (show in notification center with a notification as: uninstalling <app name>, if I restart then it will go black completely and will not go back normally, and also hold down the power button will restart it but really slow so probably it boot to something, EDL for example, not like cold shut down.
[Thinkpad Tablet Android Development] XAedgeS:
Try wipe cache/dalvik partition in TWRP, I tried that one and seem like the problem got solved. But truly, it happened just randomly, even on random app.
[Thinkpad Tablet Android Development] adazem009:
These bugs are ROM-specific, nothing I can change in the device sources. But volume changing should be possible. I think I've seen it somewhere in the device tree before.
[Thinkpad Tablet Android Development] XAedgeS:
So those are specific to RR, or LineageOS 17 also have those thing?

And as this happen pretty randomly, you have any idea for that?

And can this tablet like overclock CPU or GPU? Did the kernel have any of that ability?

Thank you so much for reply. :D
[Thinkpad Tablet Android Development] adazem009:
I think they're specific to RR. RR is full of customization options, which on some devices makes the battery life and performance worse. (probably because of some crashing processes)

I'm not sure if overclocking is supported there. I've never tried it anyway.
[Thinkpad Tablet Android Development] XAedgeS:
Thanks for reply, and again, the dark mode automatic by sunset and sunrise function is kinda not work for me too, I think it also a bug of RR right? Since if I recall correctly, LineageOS don't have that function.
[Thinkpad Tablet Android Development] Aryan@123:
Make This Rom Treble Support So We Can Install GSIs
[Thinkpad Tablet Android Development] ZONTAC:
Whenever i change fm radio channel from notification panel ,it still shows

Previous channel name(frequency name) 😑 but actually channel changed.

Is there any fix because i generally change channels from notification panel.
[Thinkpad Tablet Android Development] XAedgeS:
I hopefully this will be a bug you can fix, whenever I plug in the headphone via 3.5mm jack, the tablet will stuck in headphone mode even when I remove the headphone (speaker would not work) until I restart the device. Can you check that? Thank you.
[Thinkpad Tablet Android Development] adazem009:
Sure, I'll try that. If you find more bugs, please test if it happens in LineageOS 17.1 too. It'll help determine if it's RR specific.
[Thinkpad Tablet Android Development] XAedgeS:
Alright, I can confirm that it also happens in LineageOS 17.1, so not RR specific (probably?).

Edit: Hot damn, I'm not sure, but I also tried on Lineage 16.0, and it also happens.
[Thinkpad Tablet Android Development] adazem009:
I've tried it on my TB-8504X and it doesn't happen for me. Audio starts working when I disconnect the headphones. Which firmware are you on? Try S001031.
[Thinkpad Tablet Android Development] XAedgeS:
TB_8504X_USR_S001031_1912041525_Q12000_ROW

This is the version I'm currently use, but I use Lenovo tool to get back to stock, is that a bad idea? And I don't know why but Qfil refuse to recognize my tablet, so that's why I had to use Lenovo tool, does this tablet need some kinda of specific USB driver?

And when I back to stock, it work as normal as I want, plug in headphone -> headphone have sound, pull the jack out -> speaker have sound, on both RR and Lineage then speaker wouldn't have sound.
[Thinkpad Tablet Android Development] adazem009:
I'm not sure what could be causing it. It works fine on my device (in RR). Maybe a `logcat` will tell more...
[Thinkpad Tablet Android Development] XAedgeS:
Here is the log, I did exactly like this:

1. Turn on music on speaker -> Sound from speaker works normally.

2. Plug in the headphone to 3.5mm jack -> Sound stop from speaker, sound start in headphone (normally).

3. Pull out the headphone -> Sound does not return to speaker, stuck in headphone mode (even when I turn the volume up, it appear the high volume thingy which supposed for headphone), plug in headphone again don't make headphone have sound too.

And I'm back on RR right now, tested on RR.
[Thinkpad Tablet Android Development] adazem009:
Thank you, I'll try to compare it with my device.
[Thinkpad Tablet Android Development] XAedgeS:
@adazem009 , may I ask the exact specs of your tablet just in case?

Mine is TB-8504X, have sim slot LTE.

Snapdragon 425, 2GB RAM and 16GB of internal storage, 5MP back camera (I think there is a 8MP variant).
[Thinkpad Tablet Android Development] adazem009:
Same (5 MP back camera)
[Thinkpad Tablet Android Development] XAedgeS:
So that's good, as I worry about the 8MP variant might be the different.

And somehow, recently mine often reboot into TWRP in middle of the night while I sleep, randomly, and yesterday was the worst, it just snap black screen while I was using, then throw me to TWRP, then bootloop. :D
[Thinkpad Tablet Android Development] Hausemaster:
I have the 8 MP camera variant....
[Thinkpad Tablet Android Development] XAedgeS:
Are you running RR rom? IF yes can you please try some of the bug I encountered please.

Thank you in advance.
[Thinkpad Tablet Android Development] Hausemaster:
Sadly, no, I really needed calls so, I had to downgrade to los 16, tell us what the bug is, I will try to remember it from memory (I used this rom for about 2 months, so, yeah...)

Edit: I corrected a few autocorrect mistakes, sorry about that...
[Thinkpad Tablet Android Development] ZONTAC:
I have 8 mp varaiant , everything is working perfectly in RR rom, for me RR better than Los 16 and 17 due to smoothness and face unlock in RR.😊

Edit : Even RR fixed my null imei problem, actually in los 16,17 sim works but system shows imei no. Null.
[Thinkpad Tablet Android Development] ZONTAC:
Hey dev we all are eagerly waiting for los18.1 (android 11)😀 .

Is there any upcoming updates for RR rom.

Again thanking you for such a efforts for us.😊😊.
[Thinkpad Tablet Android Development] adazem009:
Outgoing calls are working fine for me. Try to call someone in LOS 16.0 and check if your data connection during calls is H+ or LTE (4G). If it's LTE (or 4G), you're using VoLTE.
[Thinkpad Tablet Android Development] Hausemaster:
I did some testing and found these results... From Lineage OS 16, my current ROM

If the 'Enhanced 4G LTE Mode' is off, the calls don't work at all, even with and without internet/data, as soon as I turned on the 'Enhanced 4G LTE mode' the calls started to work normally, also my carrier only supports 4G (Jio), so, I think you are right about VoLTE, also, even in other devices, this is the same for all devices, for example on my secondary phone, the same thing happens...

Also, I don't remember seeing the 'Enhanced 4G LTE Mode' in any Lineage 17.x based roms for this device...

Edit: The connection during calls is always LTE, since my carrier Jio only supports 4G....
[Thinkpad Tablet Android Development] XAedgeS:
Alright, here go the list:

1. Plug in headphone -> Listen normally from headphone, speaker no sound (this is normal) -> Unplug headphone, still no sound from the speaker, replug headphone also make both don't have sound, only can fix after a restart.

2. Package installer sometimes bug out, cannot uninstall or install anything -> TWRP wipe davik/cache fix this.

I think that's it, the two most frequent bugs I met.
[Thinkpad Tablet Android Development] Hausemaster:
As far as I remember, I didn't encounter the first bug, but, I have encountered the second one a few times, my workaround was to clear the data and cache of the package installer, then disable it, force stop it, and then enable it again, this workaround fixed my issue
[Thinkpad Tablet Android Development] XAedgeS:
Alright, thank you, I think mine 3.5 jack probably went bad with the year, at least wireless earbuds work fine. :D

Please Build Havoc OS Rom Please
[Thinkpad Tablet Android Development] Hausemaster:
Firstly, the Dev is working on Los 18.1 for this device the current status is that the ROM gets stuck at the boot animation, what we can expect from this info is that, as soon as the Dev boots the Los 18 ROM, then he will be able to use similar device tree and overlays from it and build other more feature rich Roms, etc... Till then, we'll have to wait... Or, if the Dev decides to implement treble by repartitioning and building a specific custom recovery with the updated partitioning support and fully fledged treble overlay implementation, then, we can just use any other treble based ROM, and even treble images directly from Google if a/b partitioning is implemented, but, since this device has only 16 GB of internal storage, implementing a-only is a necessity to store any userdata...

Edit: the Dev already tried to build Havoc, but, it ended up not recognizing any Sim cards, so, he had to scrap that idea, and also since Havoc ended android 10 support, the Dev chose to build RR since RR still gets updates for android 10...

[Thinkpad Tablet Android Development] Hausemaster:
You might have to extract the zip file and there a file needs to be edited to fix this
[Thinkpad Tablet Android Development] Hausemaster:
These instructions should help you

for ERROR: 7 you can unzip the OS and then go to meta inf and try to find update script in any of the folder ,,, open it in notepad and edit the codes and replace tb-8504X with tb_8504X and then save it as it is ,, without having any extension ,, compress it again amd then try

for "Failed to mount '/data' " ,, In the menu of twrp recovery --> wipe -> Advance wipe-> select data -> click on repair and change partition -> click on repair partition and swipe -> come back and click on change partition and change to partition to FAT OR exFat by swiping -> and again change your partition to EXT4 -> come back to main menu ,, -> Reboot ->Recovery

[Thinkpad Tablet Android Development] OvenCrate:
There's a typo in the META-INF/com/google/android/updater-script file. The 5th line is the following:

getprop("ro.product.device") == "tb_8504" || getprop("ro.build.product") == "tb_8504" || abort("E3004: This package is for device: TB-8504X,TB-8504F,tb-8504x,tb-8504f,tb_8504; this device is " + getprop("ro.product.device") + "."););

Notice that "tb_8504" is listed twice. One of those should be "tb_8504x." I edited mine locally and it installed successfully. @adazem009 you should fix the upload.
[Thinkpad Tablet Android Development] Hausemaster:
This issue isn't present in the latest firmware for this device, download it from here https://firmwarefile.com/lenovo-tab-4-8-tb-8504x

Download the S001031 version, then start up qfil and put the device in edl mode, hold both volume up and down buttons before connecting to PC or just reboot to edl from twrp, then it'll install the for!ware and you'll be ready to go from that point

[Thinkpad Tablet Android Development] Hausemaster:
How long did you let it run? And also make sure that your recovery is up to date... And also make sure that the installation zip file isn't corrupted, it it's corrupted, it'll get stuck in the same fashion just re-download the rom and try again, and if still it remains the same, start from scratch (flash the stock firmware, then unlock bootloader and try installing this rom...

Edit: Are you using a keyboard and mouse in the recovery or is the cursor persistent at all times...

[Thinkpad Tablet Android Development] Hausemaster:
Yes, I do use discord, my username is Hausemaster#7906
[Thinkpad Tablet Android Development] adazem009:
I think it's correct, the first command checks if ro.product.device is tb_8504. If that fails, it goes to the second command, which compares ro.build.product. If even that fails, it calls the abort command.

@zahosss Try to flash the ROM again and don't forget to format data after that.

@zahosss When a ROM reboots to recovery, it usually means that it cannot decrypt data. Formatting data should fix it in most cases, but I have no idea about your case. It just works for all people here and the only thing that could help is to reflash the Android oreo firmware.

I've found that since last weekend, my Lenovo Tab4 8 with this ROM on it shows connected to whatever network I try but says that there is no actual connection to the Internet. Here's the really weird part though......the tablet is still getting notifications (Facebook, SmartNews, Google Play, email, etc). They are coming in at the same time as my Pixel 6a and my 10" Lenovo tablet so there must be some connection, right? I've opened the Play Store to update apps but it says "no connection". Anyone got a clue what is going on with this thing and how to fix it, preferably without a reset since I can't backup the few games on it (one in particular I don't wanna lose the MANY hours I've spent on it and there's no way to back up it's data). Thanks!

Hello everybody,

starting about half a year ago, all the google services (gmail, calendar, playstore, maps, etc.) did not open anymore.

Today I tried to fix it by resetting the phone factory settings - unfortunately it did not work.

Second try was the googlefier app - but this one only works for emui 10+ - so its not an option for honor 8 lite.

Does anybody know a solution how I can make the phone run again?

Thanks a lot for your help!

[Xiaomi Poco X3 NFC Questions & Answers] Alrich:
Please replace your SIM card.

I had this issue before too and it drove me nuts. I did all the steps you too undertook including getting a replacement phone. The solutions eventually was to get a new SIM (Of the same number.)

Even if your current SIM works fine in other phones, there is this weird pairing issue that occurs with Poco X3. There is already another user on the forum threads with this same issue who got it fixed by getting a new SIM by my suggestion.
[Xiaomi Poco X3 NFC Questions & Answers] Ronan_the_Librarian:
Hi Alrich,

Thanks for your response. The thing is, with the first Poco X3 NFC we had, we tried a replacement SIM in it already, and we still got network disconnects and the X in the Network Reception icon. Admittedly, back then I wasn't checking whether the APN settings were going missing, but I suspect that would have been the case if I'd checked. Also, the replacement SIM that's having this problem in the current Poco X3 NFC works fine in Dad's old phone.

Is it likely that the SIM would work fine in a different phone, but still have problems in the Poco X3 NFC? I thought a faulty SIM would cause problems with any phone it was put in.
[Xiaomi Poco X3 NFC Questions & Answers] pl1992aw:
Though I don't have x3 NFC but the x3 pro, there's still some way to try.

You see the "Add APN" on your first screen shot?

Did you try manually adding the APN settings on your own?

Note down the APN setting from your dad's phone and manually type in your X3 NFC.

If you don't know the APN settings for your telecom service, you can ask your number carrier.

I guess you're in Ireland, so you can try this APN setting

Tesco Mobile Ireland APN Settings for iPhone 2024 - 4G 5G APN Settings

Tesco Mobile Ireland 4G LTE 3G APN Settings for iPhone Tesco Mobile APN Settings for iPhone In your Apple iPhone go to Settings -> Cellular -> Cellular Data Network -> APN and enter the following details Cellular Data: APN: tescomobile.liffeytelecom.com Username: blank Password: blank LTE...

www.apnsettings.org

Also remember some telecom service uses specific 4G bands that some phones don't support. So in this case, your phone can't find any signal, and it has to broadcast and try other bands to check if it works.
