Nice Android P

Plz canal YouTube solve the noise when on call?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Cologneblood:
Ivan, thanks for a great rom! But no roses without thorns. I found / have some problems:

- Connecting my S7 to my car is no problem. But after disconecting and connecting again bluetooth closes automatically after a few seconds, Only a reboot or powering down helps for the next time.

- Same happens with hotspot and tethering.

- Sometimes when entering the SIM pin the system the system reboots (caused by entering a wrong pin number?)

Nevertheless I'm still excited and with rebooting I have the possibility to use the rom without bigger problems!

My fast charging was working great in 7.1

After updating this ROM, it seems like the feature is disabled. The screen displayed "Charging" only and the amount per minute getting in was much smaller. Is that the known issue we are dealing with?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] saoudien07:
For me the fast charging is working very well, in around 2h my fone is full charged, knowing that I use to connect it when it is around 10-15%, sometime even less!

I would also like to clarify about the mic and the speaker during calls, it is working greatly!

Thanx to [MENTION=4610599]Ivan_Meler[/MENTION] for the great rom, and also for teasing us with the future realise with features of android P.

Please can you put the floating button to close all app down centraly instead of under the clock/battery icon,when we push to "Recent app".

Thx.

VoLTE not available

Hey [MENTION=8807860]navneet_1998[/MENTION]

Congratulations on your second Post here on XDA. Welcome :D

"Unfortunately" VoLTE doesnt work on all AOSP/LOS Roms for S7. And it will never be working. Also Ivan cant do something about this. Also (i know you didnt) you can't compare S7 with other devices because Samsung Phones are different than other phones.

We all know Indians cant life withouit it, but "sadly" you must use UMTS calls like on the good old days. Or Telephone booths :cool:

If you need it so bad, i recommend to stick with all the TouchJizz Roms out there. There are some Roms here you can use WITH VoLTE, but never AOSP/LOS based Roms.

And another hint: you're not the first one who asking/"kindly" demanding this. Next time, you can use the search button in the upper right corner. Just Type "VoLTE" and you will see all the good and lovely answeres we are spreading here.

With this in mind

Happy Flashing :o :good:

My S7's coma state

Since I flashed the latest version, my phone started rebooting randomly, showing the lockscreen, freezing and rebooting again and again, then it stops showing any screen at all, until it discharges completely. No button combination can save me when it hit this stage. I have had this problem before and I don't know where it came from since I flashed official ROMs via Odin, and LOS, through TWRP on my SD card.. can somebody help me? I don't know where I can find logs for this behavior and I don't want to believe this is plain karma acting against me! :crying:

---------- Post added at 02:22 PM ---------- Previous post was at 02:17 PM ----------

Can the people complaining provide logs or at least include info about the installation process (for example, clean vs dirty flash), extra modules (magisk, xposed, opengapps, etc.), any other possibly relevant info? Without logs or that kind of information it is near impossible to know what is causing failure and Ivan can't help
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] igordantax:
Thank you for your explanation! I'm kinda new in this world of ROMs, that's why I'm asking for help here.. ;)

So, I did a clean install, no magisk, but with pico opengapps. Since my phone is freezed in this moment, I can't give you any logcats yet but I noticed this behavior starts when the flashing ends, on the welcome screen. It rebooted, and I was able to log in and restore my backups, and then, it started again.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] ef1x:
I have been testing various camera apps to find wich one has best picture quality and so far open camera with camera2 api enabled in settings produces best picture quality. Beware when trying to record video you need to disable camera2 api in settings because it freezes app
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] khaclub:
Please guys check it
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] speed s:
First you have to do do a clean install

Then If you rooted with magisk, use the version magisk 16 not newer.

And for fast charging there is a module in magisk that enable it

Good luck
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] saoudien07:
Yes thats exactly what all of us have to do to reach it, thats why its location should be changed...

Magisk 16 ?? Why not 16.7 ??

I use the last one and I dont have any issues.

And please guyz when you talk about Fast charging, let us know that u are talking about fast Wireless Charging or Fast Cable Charging.

Thanx ;)
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Meemo23:
Because 16.7 may work fine for you, however it gives random reboots and causes issues. If you use 16.0 then you can also make it pass safteynet checks and use google pay and etc and is very stable. But every one has different experiences, I used 16.7 it gave me so many problems, Then reverted back to 16.0 and have been using my phone to pay for stuff and using all my banking apps and playing fortnite without a problem. Thanks to the safteynet check pass xd.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] saoudien07:
To be honest I got a few reboot, but I tought it was related to the last build, I did not suspect Magisk 16.7 :rolleyes:

I ll follow ur advice and get back to the v16 :good:

Ha and most of reboot, is when I download a file, when it got to the end, it reboot :silly:

Kind of some error during creation of the downloaded file (maybe I am wrong). Any idea??
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] ef1x:
Try using samsung browser for downloads, i had some issues using stock browser like downloading from google disk.

Also i didnt do clean install, and im using su rather than magisk.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] speed s:
Because i'm with magisk 16 and i do not get even one reboot and everything is working well...

When we talk about fast charging, by default it's about cable

But when we want to talk about wireless fast charging then we have to specify it... it's all about logic. Do you understand mr saoudien?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Juno-First:
Ok now the GPS is working it can be used as a daily driver & finally get rid of all the Samsung bloat. Yay

I have the same problem but not only with Bluetooth but also with Hotspot and Tehering. Different from my last post now all three disconnect after a few seconds. No chance to use them.

I flashed the new version 26 onto build 25 using TWRP 3.2.3-0 (latest version) and with advanced wipe (dalvik and cache). In build 25 I also wiped data (besides dalvik and cache)

Did you get an answer to the update process?? Should we remove Magisk/ Module, install the new Build over the old one, and then reinstall Magisk through TWRP ??

Thx
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] LlamaLad7:
This is how I do it, and it's been successful twice now:

Boot into TWRP, advanced wipe the Cache and Dalvik Cache, then flash the new build, and reboot.

If Magisk Manager says Magisk is still installed, you're good to go.

Otherwise, give it 5 mins, then reflash Magisk.

Either way, your modules/mods will be unaffected.

Hope this helped.

Feedback

Hello!

I've been using the August 5th build for 3 days now and I'm happy to report that I haven't encountered any major issues. The build seems to be suitable for use as a daily driver.

The battery is very good. I've gotten 5h10min of SOT on a single charge. That is with 4h30min of in-car bluetooth (with screen off), over 3h of LTE and 30min of GPS (brightness set to 16%). I have attached some screenshots with details.

Keep up the good work!

mindthegapps is a gapps (google apps) package which consists of essential google applications to get playstore functionality. It's either mindthegapps or any package except aroma from opengapps. Don't flash both.

My Builds

I recently got a G930F as a gift, having come from the Qualcomm Galaxy Note 4, and I'm amazed by Ivan's high level of skill in bringing LineageOS to our phones! Rather than donating endless amounts of money (that I don't have) to show my endless appreciation, he has given me his blessing to contribute to our community by donating my processing power: Asus GL752VW with a 512GB Adata SX900 SSD, more than half of which is taken up by Ubuntu 18.04 LTS in VMware. I don't have time to game on my gaming laptop, so what better way to use its power than to build Android? :D As such, I've added hero2lte to my daily build script alongside herolte. I plan on building until we get official support. You can find my builds here:

hero2lte

Bootloaders and modems

I mix and match the latest bootloaders and modems from different stock images, regardless of the country/carrier CSC they come from. I find that keeping up with these helps with stability and battery life, especially when flashing builds on a regular basis. Right now I've only posted G935FXXU2ERGE_G935FXXU2ERGC.tar, but please feel free to request any other variants and I'll add them to my .BL_CP folder. You can flash these bootloader_modem combos with the "AP" button in Odin.

You need not worry about being able to pass SafetyNet with my builds because I included a build fingerprint override. This passes SafetyNet regardless of the bootloader you're on. Haxynox's init_sec.cpp somehow never worked for me but this override serves the same purpose, without the need for the Magisk props plugin.
