The fingerprint scanner will never work whithout a patch. Can someone make a patch for this?

I'm searching something, but I can't find anything working on pie. I found a patch for oreo roms.

The comunity on this phone isn't really active. We could ask to xiaomi.eu devs for some help.

That is a big surprise bro! Thanks for your effort! Love you!

I flashed the ROM and everything I need is almost working perfectly. Much smooth than stock MIUI.

BTW, There are some bugs I noticed in this ROM and Android P based MIUI ROM:

1. When I connect Android Studio and debug any applications, the app runs extremely slow, when I disconnect adb debug mode, it's normal.

2. Somehow, Dialog has a weird animation, it jumps to the front with an abnormal way.

I *think All these bugs are ascribed to Xiaomi, because these bugs also show in MIUI(Android p). And there are no problems when using Android O based MIUI.

[OnePlus 6T  Questions & Answers] ChristosAn7:
Hello everyone,

I am really happy with my OnePlus 6t except for the scrolling experience. In some apps like Chrome, Instagram and Amazon it is simply off. It is either too sensitive or it simply lags. In Chrome for example if I scroll quickly my touch is not recognized and it doesn't scroll. Some Webpages work better and some worse.

Is there any way to fix the lag or at least unify the scrolling experience for all apps?

The device itself is brilliant but the scrolling lag drives me crazy.

Thank you in advance :)

Flash a custom kernel like RZ.
[OnePlus 6T  Questions & Answers] darbylonia:
Hey,

I noticed this recently too. When I use Chrome, the only browser I use, it has a weird lag where it only scrolls down only a little bit. I installed Opera to test that out so we will see. I would change to a custom kernel but I have the McLaren edition and I don't want to lose warp charge.

So yes, I have experienced this as well, but only in Chrome so far! Maybe you could try a custom kernel.
[OnePlus 6T  Questions & Answers] F5:ed:
Do you use "Deep optimizing" (Battery>Advanced Optimizing>Deep....)?

I did before and experienced serious lags occasionally - not always, but have no lag-problem at all after I turned this option off.

Will a custom kernel fix the issue?

Thanks for the tip. I have already turned off battery optimization all together.

You can try it. I would try a custom kernel but I have the McLaren and don't want to lose features.

[Honor View 20 Questions & Answers] paulds:
Hi all, so my biggest bug bear with the Honor/Huawei devices is the launcher. In my opinion it looks outdated and a launcher.

I've been having some issues getting any third party launchers on the device but I've now found a modded Pixel launcher that work - link below.

Once you've installed it and before you set as your default launcher, ensure you go into the app permissions within the app and set all of them on. Then set as your see default and bingo, you've got Pixel launcher.

Enjoy, Paul.

On a side note Honor/ Huawei, please update your launcher. It's poor and looks so dated.

Hey guys,

I'm currently researching a way to upgrade my Nokia 6.1 TA-1054.

Right now the phone is on a "global" Nougat firmware which was preinstalled. I cannot receive updates and am hoping to get to an up to date version.

Does anyone know whether it's possible to upgrade to the firmware of this thread, with Nougat as a starting point?

My approach would be to unlock the bootloader, boot into TWRP and install this ROM.

I'd be very thankful for any advice. Hopefully we can establish a process for other people stuck on TA-1054 to update their phones.

Cheers
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] Maherabed1986:
if you want to upgrade your phone to latest firmware you need to look for Chinese version because your phone variant relates to China release not original global so go ahead unlock the bootloader then use official twrp boot it up then take full backup save it on ur sdcard or Computer then try to flash latest Pie firmware for October patch that's it

That post says that TWRP handles everything for me, slot wise.

I tried to follow the instructions in the OP. I did the following:

- Wiping cache, system, data and vendor.

- Switched to partition B

- Wiped the same there

- Flashed the vendor image

- Flashed the custom rom

- Wiped cache

- Switch to partition A

- Flashed the vendor and rom.

- Wiped cache

- Reboot. When I want to reboot from TWRP, it says that there is no OS installed.

I managed to boot once to AEX sucessfully, but flashed the wrong Gapps. Now I can't manage to get it working again.
