Very bad GPS accuracy (with perfect conditions - clear sky, outdoor)! 16~32m.
No matter of GPS mode (only GPS, HI accuracy...)
Two days ago, I try to make some GPS tracks in the mountain. It was a disaster :D
I'm trying Trackbook & OSMTracker... no luck.
Is this normal for A5 2106?
How I can improve accuracy?

Maximum civilian accuracy for GPS is currently 8m. But that is only in one axis. Overall accuracy can be similar to what you are seeing.

-- edit --

On my A3 it reports an accuracy of 4m in the GPS test app

Hi there, I'm glad you keep the a510f alive and I'm going to try your rom. Before installing it I want to buy a new, faster micro SD card.
Can you tell me what max micro sd card size is supported? On stock Samsung claims 64GB, 128 GB also works.
Best regards.
64Gb Ultra SD is ok

My A5 trees are cleaner, more stable, and are actively maintained. Bunnyy hasn't updated his ROMs in a while.

Hi,

Just uploaded a new release (23/06/19).

I have added a new fix for the camera HAL which solves any remaining Snap crashes, I have also tested this with Google camera (from OpenGapps stock package) and I have not been able to crash it.

Code:
Changes in the 23/06/2019 release:
[INDENT]camera: added new workaround to fix remaining HAL crashes (Google Camera should work now)
June Android security patch
LOS updates
[/INDENT]

Regards,
Danny

I have not seen this issue and this has not been reported to me.
There were amplifier issues in my early releases, have you updated to my latest (prior to the one I just posted)?

If you produce a logcat I may be able to debug the issue.

Danny

I dont understand where problem is. I tried speaker on music player and whatsapp call. There is no problem.
I tried 3 custom rom. There is this problem for AOKP-oreo and this Lineage OS roms during phone call. Finally I found solution for DotOS v2.5 rom.
Thanks buddy.

As I said in my last post.

If you send me logs I can solve your issue, for audio stuff I will need a logcat and a dump of /proc/last_kmsg at a minimum.

The main problem you will have with any of Bunnyys ROMs is that he has stopped supporting them.

Nice build once more. Last Friday I had issues after using open camera app. Galerie found the pics I had taking only after reboot. I didn't try to kill media server... storage location was external storage. Next time I hope I think of that. ? I'll report (log included) if it happens with this build, too, though I replaced microSD yesterday due to capacity and speed. My Sandisk was class 10 first generation but several years old.

MicroSD: Samsung Evo plus 128GB is working fine, even using it to increase RAM (max. of 4GB additional provided by app at the moment to find good size). Performance is much better now. So 64GB limitation called out by Samsung isn't true. 128GB works, available for less than 20€ of you buy in right place.

Security related question: the kernel is based on Linux kernel 3.10.x - I know stock kernel is that old, too and it's... hard to retrieve source codes from Samsung for Exynos 7580 because they simply don't care. Is there no chance to switch to an up to date base or is it "just" a lot of work? I tried to read into this theme but simply have no programming skills. 3000 settings cherry picking... omg. It's only that 3.10.x is missing several years of Linux kernel development and security "patches" and phones are vulnerable due to this. Don't misunderstand, I adore your work and I am just interested and curious. In a few months I will ask if there is a chance to implement ark (open source) and replace art. ?

Many thanks for keeping this great ROM up to date, I had no problem with it since flash (~1 month ago)
I was looking since a long time for an more modern and up to date ROM for My A510F, I think I found it !

Looking forward for an LOS V16 version !

    Introduction

    Thanks to my very generous donors I managed to buy an A5 2016 cheap on eBay and have ported our new device tree and kernel to this device.

    This is far more stable and much snappier than the previous releases available as the new kernel/tree is much quicker.

    Features and Improvements
    Stable
    Fast
    What works
    Calls, SMS, Mobile Data
    Camera
    NFC
    WiFi
    Bluetooth
    Torch
    Fingerprint scanner
    SELinux Enforcing
    What doesn't work
    Some 2D animation stuttering (WIP)
    Occasional Camera HAL crashes (same HAL bugs as A3)Fixed in 27/05/2019 release
    VoLTE (will never work on LOS)
    You tell me​
    Installation
    1. Download the latest LOS build and transfer it to your phone
    2. Install the latest TWRP (Available Here)
    3. Make a full backup (just in case something goes wrong)
    4. Do a full wipe (Cache, Dalvik Cache, Data, System)
    5. Install LOS
    6. If you are installing GApps do it at the same time (preferably in the same install queue)
    7. Install Magisk if you want root
    8. And finally boot, the first boot can take several minutes as it optimises all the apps
    Downloads
    Latest releases are uploaded HERE
    OpenGapps HERE
    TWRP is availableHERE
    Magisk is available HERE

    Hi,

    Uploading a new release now (27/05/19).

    This should fix any camera crashes (lost focus, hard lockups, etc), I have been thoroughly testing my new fixes and haven't crashed it yet.

    Google camera (from open gapps) is still buggy but in debugging it I think it is the app doing strange things rather than a specific hal issue, it is known to cause issues on other phones so i would still avoid using it, best results are with the built in camera app Snap.

    Code:
    Changes in the 27/05/2019 release:
    [INDENT]camera: improved camera wrapper to fix camera crashes (still avoid google camera)
    LOS updates[/INDENT]
