Sorry. I was drunk yesterday
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] PedroMedeiros:
Hi!

Be healthy, and do not have drinks while writing code.

Just one question: in the previous release I was able to change a kernel setting in order to set the minimum number of big CPUs always online. Now this setting was gone and the 4 big CPUs are always online consuming battery. Did you update the kernel sources on this release? Maybe something changed and the kernel interface to change this parameter was removed.

Anyway, keep up with the excellent work and dedication.

Cheers

Just drunk when post here

Yes. Did you feel better before the previous version? (that is 18/6?)

And helium or hydrogen ?

waiting for latest release EvoX...:D
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] PedroMedeiros:
Hi,

Sorry for the delay. My battery got swollen and I had to replace it, as the phone still works great! Maybe this time I will disable the fast charge, it lasted 2.5 years.

By the way, my phone is helium! In the overall I preferred the previous kernel (18/6) as it is more CPU configuration friendly! I noticed that on this current release, there is no option to configure the minimum big cpu's online and they are all online most of the time, thus increasing the power consumption and decreasing battery life. Is the new kernel related with the wifi hotspot fix??

Cheers!

Where did you buy the replace battery ?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] PedroMedeiros:
Yeah! It happened to me when I moved from miui android 7 to pixel experience Android 9. I searched a lot to fix it and it's recovery related. If you use the orange fox recovery it's ok, full working, everything back to normal: https://xdaforums.com/mi-max/development/twrp-orangefox-recovery-project-t3924950

---------- Post added at 10:06 PM ---------- Previous post was at 10:01 PM ----------

I bought it in a store (Lisbon, PT), as I wanted to fix this issue asap (my phone died this weekend, so I just had it offline yesterday and today). If you are not in a hurry, you can buy original battery in Amazon, eBay, and so on... And it's easy to do it at home.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] PedroMedeiros:
I used the one for helium, as my phone is mi Max pro, use the correct one 4 you: https://androidfilehost.com/?w=files&flid=293374

It worked for me, previously with twrp after the Android 9 update I got everything encrypted under recovery. Ps: I updated my phone with the last official firmware before the update to Android 9, don't know if it makes a difference.

[MENTION=2772810]dungphp[/MENTION] I am using foe.kernel (https://xdaforums.com/mi-max/development/kernel-foe-kernel-t3946025) with the last version of your rom and everything goes smoothly, working great. I got the cpu hotplug tweaks to work again with this kernel. It's great. And the new battery seems like a miracle, battery consumption is much better now. The previous battery was completely destroyed :D ahahah With an optimized kernel, a new battery, google camera and your fresh Pie ROM who needs a new phone? Helium with 4 GB of RAM still rocks! Thanks for that!

What are the differences between CAF and AOSP version? What is most stable? Thx in advance :fingers-crossed:
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] dungphp:
The name says the difference. One side of the source code directly from Google, one side has source code from Qualcomm.

In CAF version have some more fix in sources like as camera, wifi hotspot

I think AOSP will better then CAF

Are you using a Hydrogen or Helium?

If Hydrogen, are you able to encrypt the device? I'm having issues with my Hydrogen(coming from latest stock and tried latest TWRP and OrangeFox as well.

Dow anyone know of a zip file to enable the encryption back?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] PedroMedeiros:
Helium... I just came from miui stock (most up-to-date) to this rom, and formatted system partition and data (not including storage), and twrp recovery was unable to do backups or system restores, or even navigate in those partitions. The alternative was to format the system completely or get an updated recovery. OrangeFox worked out-of-box pretty well for me, with system encryption. Cheers!

If I can share my experience with the latest build 26-07-2019 pixel:

When incoming calls and press off button it comes back to the screen the screen don't go in off modus every time I press screen go off and on again while someone is calling me very annoying.

Battery go faster but I give it more chance few days to settle this is my third day in usage.

I miss customization the ROM like clock middle network left in top examples like this do you have plans for it dear dev.

Battery drain very fast using gcam.

Several times Google play services is hanging can't access and download anything Google use apps

For the rest it seems great

PS hope to see updates and more stuff and dev thank you very much for all your efforts

Not call recording... Eg: when you record a video via WhatsApp or Instagram story, or just basic video recording with Google cam.

The sound is like **** quality.. I think it's because of noice cancelation.. I can provide a demo audio file recorded from my phone for reference

This is a video (song) recorded with Instagram... The audio is not so good.. it sometime get high and sometimes low... It's not study

---------- Post added at 02:26 AM ---------- Previous post was at 02:19 AM ----------

When you install any rom at initial setup google asks for installing your previous data(backup) if you choose yes this notification will come to recover your backup via wifi, choose no if you don't want to install that, notification disappears.

Now in this situation you have to give wifi to google to recover your data backup and it will disappear.

Auto screen brightness needs optimisation, its too bright and eats up battery really fast.

Have found an issue with Pixel Plus Latest release.

Am using Helium 128/4gb.

When i have a Bluetooth headset connected, the notificatins only play in the headset, whereas, in MIUI and other phones i use, notifications play both in the headst and the phone speaker.

If for example i have a Bluetooth headst connected, but I'm not wearing it, then i would not know if i receive any messages or notifications.

So basically this needs to be fixed. Notificatins should play both, the phones speaker and Bluetooth headset.

I've found this to be a problem with all custom Pie Roms.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] lakshyajeet:
I think that's not a bug,MIUI always use to give extra features in their phones, where as asop or los based roms are more inclined towards to give google based simple and practical features.

So if you plugged bluetooth headset notification sound will be played in headset rather than in phone speaker.Also we don't get call recording feature in roms which is a basic feature offered by miui(google dont provide it due to privacy).
