Bugs In All Versions of Nougat (LineageOS) that I have found on GT-I8730?

My Phone: Express GT-I8730 running Nougat Rom (lineage-14.1-20170822-UNOFFICIAL-expressltexx)

1. Everyone who calls me says they can hear a bad echo of their voice as they speak, but everything sounds normal on my end.

I have called my phone from another phone the echo was very bad it was very difficult to talk to my phone! How can I fix this Problem?

2. Also during phone calls I can't turn the volume up or down, the audio volume stays the same it does not matter if it is at full volume or volume is off the audio never changes! The volume display bar goes up & down but no audio change.

3.The GPS is very bad it constantly drops the signal & it can take anywhere from 1 second to 7 minutes before GPS picks up the signal again, indoors GPS is even worse. I have tried editing the gps.conf file but that did not do anything. I have tried a few GPS apps (Gps Test) to see what is going on, I have found the GPS has plenty of satellites in view but has trouble locking onto satellites, GPS only locks onto anywhere between 2 & 8 satellites & constantly drops out.

4. Google Duo & Google Hangouts apps microphone does not work at all, I have a work around to get microphone to work on Hangouts app, Hangouts has a setting to select microphone after selecting microphone Hangouts mic works but no such luck in Google Duo as it does not have the same setting as Hangouts.+

5. Cellular network not working, only works after flashing rom or factory reset, after I turn off cell Network & then try to turn it back on the Cell Network stuck in connecting mode & won't reconnect, same thing happens when I reboot the phone.

NOTE: I installed my stock JB 4.1.2 rom to rule out any hardware issues, With Stock JB 4.1.2 Rom everything works perfectly

The GPS Locks onto 15 satellites indoors & over 20 outdoors, Phone never lost the GPS signal, No Echo during phone calls, the volume is adjustable during phone calls & Duo works when I was using the JB 4.1.2 Stock Rom.

Thanks for All Your Great Work, everything else works well, very stable.

Go to recovery and factory reset.

I had this issue and now it's fixed.View attachment 4256903
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] Niltava:
Cellular network not working after installing superSU binary

First of al, thanks for the great work that made this ROM possible. Almost everything works fine, there is only one thing: When the superSU zip is flashed (downloaded from the attachment in the OP), you can't connect to the cellular network anymore. Only a factory reset solves this, but removes superSU along with your root access. I tried wiping Dalvik/ART cache, Cache and Data one by one but that didn't gave me my cellular back, only a factory reset and thus disabling app root access works.

So for now it seems that I have to choose between cellular network access and root access. Is this possible to get fixed in the near future?

EDIT: Now root for apps and ADB is working after a factory reset, so everything is fine now. I don't exactly know what fixed it but the steps I did after a succesful LineageOS flash were:

1. Flash superSU zip

2. Notice that your cellular is gone

3. Wipe Dalvik/ART Cache

4. Wipe Cache

5. Wipe Data

6. Factory reset

7. Everything suddenly magically works

There are probably duplicate actions in the steps I did but this worked for me.

EDIT2: aaaaand after a reboot, the cellular is gone again... sigh...
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] Niltava:
Follow-up: No matter what I try now, cellular isn't working at all now. I've wiped everything including internal storage and system, re-flashed an did factory resets but it won't work. Seems like I'm going to downgrade to 7.0 until this is fixed.

EDIT: downgraded to the build from 26 january 2017, everything seems to work fine now, even after a couple reboots. Cellular and root are working without the need to flash the su binary.

[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] cd716:
Sorry for that bro. It happened to me few days after and I've had to downgrade it to 22052017 build to get cellular network working again.

I've tried dirty and clean install the 20170701, 20170723 and the last builds, formatting the data partition, flashing stock ROM on odin and starting fresh and no way to get it working.

in service mode (dialling *#*#4636#*#*) I've seen that the cellular network service was trying to connect but it not pass there even when I changed it to other band.

So, I will stay on 20170522 build until the next update.

Hello, I've never thought that it would be possible to upgrade the i8730. I just found this thread.

I have an original i8730, Android 4.1.2. that I do not use for a long time now. It is slow but the image is still amazing.

- I am not sure about the differences between the i8730/T - i8730 (EOL) - "just" i8730...?

- I am also not sure if I should try the CM14 right away, or try an earlier version first (4.4.4 or 5.1.1)...?

Thanks in advance for any support guys...!

Edit: [MENTION=6575747]cd716[/MENTION] any tip, suggestions to start with...?! Thanks!
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] cd716:
The GTi8730T is a variant from Vodafone Australia. It's the same hardware that the GTi8730.

You can upgrade it directly to nougat or try any previous ROMs.

It's your choice. Just follow the instructions in OP for the ROM you are flashing and you are ready to go

To get the cellular network working on the last builds go to settings -- developers options and enable the advanced reboot menu. After that just soft reboot your device twice.

Hello, I have the "14.1-20170522-UNOFFICIAL-expresslte" version for almost two months now. It works very well, however it has a rather slow reaction: It takes time to change screens, to open an app, to get off the locked screen, etc.

I wonder if anyone here has managed to improve the fluidity of the phone. Maybe through some configuration of the "governor" or other settings ...?

Thanks in advance for any tip...!
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] nunopenim:
I would suggest update it, of course, as a first. Kotzir did some tweaking to kernel in the latest releases. If that still doesn't work, maybe turn off animations in developers menu? It will be a little more ugly, and no smooth transitions, but it would be faster for sure.

Abraço :)
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] RFMC:
Ok, I will update it. And I will also change the (old) SD card for a faster one (?) as I got a system warning about a slow SD card in order to install apps...

[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] RFMC:
Hi, so... after some days testing the latest ROM, I decided to return to the "14.1-20170522" again.

I found the latest "14.1-20170930" less fluid and more battery consumer, even with animations twicks.

The "14.1-20170522" is not that bad, actually is pretty good. Perhaps current apps just became to heavy for this hardware...? For Instance, I can't have an Office editor working properly in this phone...

Thanks again...!

All the best

Our phone is getting old :( I have mine since December 2013, it's been 4 years. When CM13 was released, I was actually impressed. Didn't expect it to work at all fluidly, but it kicked ass :) Still does if you use it correctly, even with LAOS-14.

Abraço :)
[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] RFMC:
Hi...!

"Correctly" is a key word. I am not very skilled about smartphone settings.

I am mostly a "light" end user. I don't do games or videos. The heaviest app I use is the FlightRadar24: it may empty a battery in 3 hours (lots of processing + heavy data connection).

My i8730 was in a drawer for a couple of years while I used a Mi4C: lots of power + lots of space + lots of heat...!

After a catastrophic accident here I am, again, a happy user of an i8730, still struggling a little to find how to correctly use it... :o

Many thanks...!

It's probably EMMC corruption. You probably need a JTAG. That happened with me before. I was having lunch, felt the phone vibrate and it was in DL mode in QCOMM_USB or something like that.

You are right, it is from 2012. I will cite [MENTION=5344004]kotzir[/MENTION] on this one. Our phone is shipped with 3.4.0, and porting to a higher, let's say 4.4, or even more (no clue what is the latest version) would be very difficult. Kotzir implemented 3.4.113 in an effort of making us more updated. I conserved all the sources and all his work, and just updated the android version and the security updates. That's the reason we still use 3.4.1

The kernel is designed to run on the I8730XWAMK1, all the kernel sources were made from that version. That's why :) I8730XWANE1 works fine for unknown reasons, but all versions between I8730XWAMK1 and I8730XWANE1 should work (should, doesn't mean they do)
