Hello

On last build I've seen blue led and black screen twice, on previous build once , few before the same. I noticed this when I was browsing webpages via firefox. Screen was freezed, no response when touched and... black screen. Now I trying on chrome, but is too short to say something. Leaked memory/script with too high cpu usage/touchscreen??? I would like to help more to resolve this problem. How to publish logs or something what could help to track this problem? I Use phone a loot for GPS/Music via BT , internet browsing and 1h talk everyday. I noticed another strange behaviour . Two times , two different compilations 14.1 my screen was trembling (mostly visible on edges on left and right of the screen, like problems with backlight or adopting screen brightness by sensor. After system restart everything was OK.

Hoping to help @Electry and all users i uploaded the last build here: http://cmserver.malaga.cloud/builds/delta/cm-14.1-20161113-NIGHTLY-kingdom_row.zip

If it's a problem, i'll remove the link.

Anyway i installed cm14.1 on both K920 and s4 mini to see differences.

4 bugs or issues.

I have started getting cell broadcasts suddenly. :D

I think power saver mode is ineffective. For me, it only dims the screen but otherwise rest of the background activities and data use stay active.

Headphones with calls are useless because the opposite party can't hear what I'm saying without shouting. Maybe mic volume needs to be raised or something.

When the battery is at 2%, it stays there for a really long time. I have had once kept the device running on 2% battery for 15 minutes watching youtube only. I couldn't dare to leave the device unplugged beyond 15 minutes. I thought it might pose a threat to battery whose voltage could fall below the recovery.

Samsung note 4 to S6 edge also suffered from the same bug. We do share a lot of hardware with note 4. On some forum I read the issue arises from a setting inside accessibility menu. However that particular option inside from accessibility which was causing the issue has been removed by google in Android 7. From the looks of it, the issue isn't very serious. It seems the condition where the OS is confused whether the display is running or not. It uses a lot of battery on black screen so it means it's in some deadlock condition. I think below the black screen the device is running okay. If you guys face this issue next time, can you check if you can use Ok google commands or not. Tell it to turn on the flash light.

I know it's a long stretch, but if gurus and pundits look into source code of the accessibility menu, try to find if any code actually calls for LED, we might find the root of this issue.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] malaga82:
note4 should have snap805, as i know we share "a lot" with OPO/X...and since official cm14.1 appeared for OPO here , maybe we can have some issue solved
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
BTW, do you think our custom ROMs would open up support for LTE 2300MHz band? Asking because snapdragon 801 supports that band but Lenovo doesn't officially mention it in the spec sheet.

Electry, what about the security updates - or the so called "patch level" ?

I usually update around the middle of each month to get the 5th of {put here the current month} of Android security update ( BTW, I know there are 1st of month and 5th of month Android security updates each month released by Google, I don't fully understand the distinction).
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Electry:
You are right. What I should have said was that you don't need to update every week, or perhaps that you shouldn't expect a lot of changes between each build (other than security patches).

I have two SIMs from Vodafone and Idea networks. Both are 4G capable with active 4G plan. But, I'm unable to connect to speedy 4G with either one.

Vodafone: This doesn't want to get into LTE mode no matter what. But if it gets into LTE, it's reliable and speedy. However, 99% of time, it just keep switching between H and H+ every few seconds. It's unable to maintain active voice and data connection if it's not in LTE.

Idea: This easily connects to LTE and stays connected. However, 99% of times, speed isn't more than 0.5 MBPS. Only rarely it'll give decent speeds.

To establish reliable and speedy 4G, I have to keep switching between APNs, *#*#4636#*#* network types, airplane mode on/off for like half an hour everyday (no exaggeration). Sometimes, I get much better speeds on 3G only mode than LTE.

I have contacted both networks, got both SIM replaced, sweeped the SIM slots, but the issues are consistent from Last November. Doesn't matter if I use 7.1 or 8.1.

What can I do? Do you have different drivers for modem? Can I try that?

Thanks.

I think 15.1 official is imminent, because I have seen very few updates at 14.1.

Am I wrong ?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
I think that active development of 14.1 is done. It's just patched with security updates as of late. Electry told us that new 15.1 build will come out soon. When it does I'll be switching to it, no matter how stable it is, it has to be tested by us, the users.

Try Mobile repairing shop. He might be able to fix the issue without replacing. Try aliexpress in case it needs replacing. Lenovo in our country doesn't even recognise this mobile. It's hard to get the genuine battery forget sim trays.

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
Does it show for both sim? Have you tried different network sim?

Try,

1. Switch network to manual and select Vodafone from the list

2. Dial *#*#4636#*#* phone information -options - select radio - automatic.

3. Under phone information try set preferred network type to LTE/ UMTS auto (prl)

Doesn't sound like there's problem with the sim trays. Are you sure the problem is with the phone? Do you get good coverage on different mobile?

Also try Vodafone on 3G mode instead LTE.

I tried the 15.1 line, I can say with confidence that the 14.1-less cumbersome and energy-efficient oc-right developers do that bring 14.1 to the ideal and do not go to 15.1 ...

Many thanks to the developers of the team CyanogenMod for the work done! Personally, I miss CyanogenMod and their policy of releasing custom, it's not that now the team was bought in fact and Google dictates its policies ..

The trend went to the side of the maximum pure custom without mods UI-as I think it's bad! .. Custom builds have become stable, but boring .... (

Remember how many chips were in CyanogenMod-now there is no such thing and it's bad for open source

Even vendors do not understand that many people bought specific models of smartphones-only because they were issued custom-made roms with the maximum possible customization-this is a mistake of marketing and exclusives-policy stuff! ...

As I understand from the descriptions and reviews of respected sources - android 8.1 is a beta android that something like that ...

I would like to add the ability to format in TWRP f2fs data and system

sRGB color mode-switch in developer mode does not work
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
My experience,

I'm on 15.1 and not coming back to 14.1. I'm liking Oreo. It's very stable and smooth. Smoother than 14.1 for me. It's able to hold more apps in the Ram than 14.1. My 14.1 had gotten too much bloated over the last year.

Camera works better on 15.1. I had problem on 14.1 for video shooting, audio was too boosted and videos were bland, too much exposed. 15.1 videos are really good. HDR partially works. Otherwise no problem. FreeDCam provide manual exposure control which are awesome.

There're just few bugs in 15.1 as of now. But nothing big.

YouTube picture in picture mode has made the experience much better. Battery is good.

There're only handful things that aren't ported to 15.1 yet like pocket mode unlock. Nothing significant.

Yes, stock Android is boring and I've myself said it a few times. But that's why I have been using Nova launcher and 500 firepaper. I'm thinking of booting stock Google dialler for better dialler (if that's possible). Earlier custom ROMs did provide a lot of mods unlike CM or LOS but they were unstable and didn't provide 100% phone functionality. Like camera or NFC wouldn't work. Lineage tries to cover 100% phone without compromising stability. They left modding to us.

Don't know what to say really. Not even sure how expensive replacement parts are (is it even worth it???).

Me too. It still deserves to be kept, so I would also go for a working display, however I would first try to find 2-nd hand. That's how I found a replacement camera for mine - spares suppliers on AliX are not reliable in general (not to say "at all")...

I will certainly keep my device even if there is no further LOS development towards a fully working O release for it. I am happy with N and as long as the device works and future P, Q, R etc. app versions run on it, I'm fine. :) Heck technology and the needless waste it leads to. ;)

A few posts after that you see:

I didn't check if the link is still alive - PM Electry if not…

Keep in mind that Snap behaves bad. Among the few nice colored photos that it will certainly take, most of the time it records pure white (occasionally pure black) rectangles…
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
So this is still not reliable?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] user700512:
Snap is not part of LOS.

As about THIS release (14.1) I consider it more reliable than stock 288.

The only thing that I experience for the past months is a GPS problem (see in the 15.1 thread here and a few posts back).

But, since only me and cyprien T have such a problem I believe it is limited to our 2 devices, not the whole model.
