hold the volume down and power button at the boot logo screen ..THE SECOND it turns black put fingers on VOLUME UP and power and HOME AT THE SAME TIME .. it will boot into twrp .. uncheck zip verification and checksum and untick install twrp if not installed ...

now restore your twrp BACKUP YOU MADE TO SD CARD with restore function after putting back simcard

if you didnt backup ..try full wipe in twrp and flash magisk ..no gapps ..if it boots ..download diffent gapps and try that ..

or if you didnt flash gapps and magisk flash those before rebooting

or using usb transfer another twrp flashable stock rom from your pc ..

_your zip is corrupted

_ bad gapps

_ you didnt flash no verity ever

_ you didnt flash the correct bootloader version

_ you didnt do a clean flash

_ you tried to restore mougat data on top of pie

Seems like you need to update the Bootloader (BL) and Modem (CP) from the Samsung official ROM. You can get that at sammobile.

I cant seem to run gapps on my phone. I get error message and a notification saying "preparing for setup" after installing it via twrp. The notification never goes away.

Camera issue

Hi, the camera issue is still here.

Two symptoms; Sometimes camera is green for a second, and capturing a photo has delay. Its unpredictable when the camera actually captures the frame. Its not the camera app, because it happens on all camera requests from any app. The ROM should handle this correctly. I think this is a bug, because stock ROM had no issues with this.

Can someone confirm this? Does anyone know what I can try? Or can I fix this by myself?

Regards,

Lajos
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] exaveal:
Hello Lajos, i can confirm the delay. It's obvious if you use the flash: The photo is taken AFTER the flash, so the image is not exposed. The only app working is "OpenCamera".

---------- Post added at 05:48 PM ---------- Previous post was at 04:55 PM ----------

@Ivan_Meler: This ROM seems to have a problem with the speaker function during a phone call since several LOS versions: It is not possible to use the speaker during a conversation.

If the phone running LOS activates the speaker during a call, the caller on the other side will hear him/herself. This is probably a problem between the microphone and the speaker .. the microphone should not record the output of the speaker.

I have traced the problem to 5 Samsung S7 with LOS versions of 14.1, 15.1 and 16.0.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Deep Nox:
What cell phone bands does this rom use? I'm in the US on AT & T. I've used international versions of the S series. I've noticed that the international version uses band 2, while at&t main band is 12. Att has band 2, it's not as good.

Or, can I change the cell phone bands used in this rom.

Thanks for a great rom and the hard work.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
You'd need to flash the latest available baseband for your country, by downloading from sammobile the official image for your country and flashing just the modem using odin

Regular reboots after flashing 16.0

Thanks for offering LOS for the S7.

Just updated to LOS16, but now I have regular reboots, out of various apps. First I suspected Apex, as it got more reliable when I changed to another launcher, but now reboots started again.

Today even K9 started to crash the phone, repeatedly, when opening a message.

During a reboot, the phone first freezes for about a full minute (nothing at all works then), then it reboots quickly.

I came from 7.1.2 on my rooted S7 (which worked perfectly fine and reliable), I did the following:

- backups with Titanium

- wiped data, system, all caches

- flashed 16.0, using most recent TWRP

- installed all apps using Titanium

- added all app data using Titanium, SMS via MyPhoneExplorer (as it didn't work with T.)

Of course, I have no Gaaps, but AFWall+, etc.

I have no Magisk, but SuperSu.

Question: What I did, was that a 'dirty flash', or was my procedure sufficiently 'clean'?

Any hints what I'm doing/did wrong?

Otherwise I'll just return to 7.1.2 (but going unofficial from official sounded quite complicated, to get updates and patches).

Audio recording

I noticed a small bug when recording audio with any LineageOS ROM on S7, not only this one, but 14, 15 and 17 as well... if you try to record your voice, or anything, you will hear "clicks" when listening. It happens in new installed phones, everything is clean, formated.

Did anybody tried sound recording and confirm ? If not, can you please try to record your voice, say like slowly "ahhhhhhhhhhhhh" "ohhhhhhh" for some seconds and hear the results ? Silences produce nothing, but as soon as you talk normally or sing it produces those "clicks".
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Try to disable "OK Google" speech recognition.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
There's no gapps, no OK google, it's a clean lineageos install.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
Regarding the sound recording problem... how to reproduce + example

So, regarding the Magnetophone or any other sound recorder problem, how to reproduce the issue:

- Install a fresh LineageOS (I've wiped everything + formated)

- open Magnetophone app

- record your voice, sing a little bit, say "ahhhhhhh" or "ohhhhh" for 5 seconds

- listen to your recordings

- normally you will hear "clicks" over your voice or when there's any sound, nothing when there's silence.

And here's an example with a music I recorded for 1 minute: https://wetransfer.com/downloads/2ec3d0b7bb667eaa6b4e69983fd1dd9320200114162125/737439

It's not a phone problem, it works with a stock rom, and I tried on two phones, same issue.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] And707:
Hmmm...

Well, I downloaded the ROM from the link on the first page of this thread, checked MD5, and it was all ok.

So, I'm currently not sure at all what the problem is, but if I read between the lines, you're basically saying my procedure was correct, but it still doesn't work (for whatever reason unknown). Maybe I just need to re-flash then and all will be fine... I (?)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
backup everything

**all partitions

do a full wipe of internal storage

install the rom

don't "restore" anything

boot the rom and set it up without restoring anything

see if the problem persists ..if it doesn't ..the cause is a dirty flash ..or restore issue causing problems..

if the problem persists on 100% clean install it is a rom bug and you need to take logs and submit a bug report to the rom maintainer

problems with alarm headphones and speaker

hi,

first i'd like to apologize for my bad english, it's just not my native language, so...

i just flashed this rom, all went fine, but last night alarm wasn't able to wake me: i like to go to sleep with my headphones plugged in, fell asleep and the alarm sound just came out of my headphones, not the internal speaker as usual.

i was on android 7 till yesterday, alarm went through speaker AND headphones simultanously.

i already re-flashed the device - dirty flash, then again complete, after dirty-flash didn't succeed - the "error" still remained.

is there a solution - yes, i know...a normal radio-clock... seriously :)

greetings

Please, stop reporting issues with speaker phone calls, it is a known issue and will be solved when possible.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] exaveal:
I think it's really important to see if a problem occurs on all installations or just on one specific phone. It's the only possiblity for a user to see if it's an individual problem (hardware, configuration, ..), or if it's a general problem of the software.

I have 2 of these phones as daily drivers, both are randomly restarting, apps are not loading when clicked, blank screens after boot.

What logs are needed, it does look a software problem.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
take all logs using this apk

https://play.google.com/store/apps/details?id=com.tortel.syslog

this application can scrub personal data

just grab all the logs and then explain in detail what you were doing when the phone restarted ..also explain or take a screenshot explaining your setup ...( if you use magisk and which modules )

the dev won't answer if you use xposed or if you restored system stuff with titanium because these are two well known causes of crashes or restarts

*** in my personal experience Ivan is not one to answer very often or directly to users

**** xpressluke answers occasionally but he usually depends on lineage changes by Ivan that is implemented into his new builds

i gave s7 to my daughter ... I didn't enjoy a Samsung device ..S7 is "old" now ...etc ...anyway none of the roms custom or stock ported ...or even stock rooted could satisfy what i wantedwithout bugs and everything working ...even some of my low range mediatek phone was more enjoyable...:p
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] padraigdoran:
Ya, S7 is old but it's still a viable device for everything I need.

One phone had fresh clean install of everything, the other had some user apps restored.

Will that app provide enough detail for random reboots and hard reboots after system lockups?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] JaimeZX:
Guys, the speakerphone echo problem is because the noise-cancelling algorithms are Samsung proprietary. Lineage (and Ivan) cannot use them. Therefore there is no noise-cancelling unless someone writes their own custom code to replace that for the LOS project.

Edit: I *agree* it's super annoying, but the only alternative is to extract that part of the software from the stock ROM, and install it as part of your own custom LOS build.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] And707:
Ok, but...

Ok, thank you for this clarification.

Fair enough, but why is this then not listed under 'not working' at the start of this thread? It's very important functionality, highly annoying, my phone has a very bad reputation among some of my contacts just for this.

Being open about such problems would clearly help.

Mine took a fairly long time to reboot after the update and a few apparent reboots with 'Updating System' warnings and then , after waiting a while to see what would happen, I went to restart, my login screen came up and said there were needed updates and I should turn on WIFI.

I just left it alone and everything went back to normal.

bluetooth headset volume too loud

Hello,

I'm having a problem with using my recently bought bluetooth headset for phone calls: minimum volume is way too loud.

I've search for solutions and some people have the same issue with S7. Some people solved it with tweaking the equalizer, some other bought a bluetooth headset that have a low minimum volume, and I've read that system/etc/mixer_paths_0.xml could be modified to help that.

Problem is there 's no equalizer in the rom, the headsets known for having low minimum volume are pricey and I could not find how to get permissions to write in mixer_paths_0.xml file.

Any idea?
