Crash within Unity 5.1.2p3 for 2-5% of our Android users

Hi folks,
We had briefly (for a few days) put out a version of our android app that was built using 5.1.2p3. We reverted back to our build using 4.6.x because our crash rate increased dramatically (from less than 0.1% to around 5%), but it was crashing in a place that did not seem because of our code:

Mainly want to find out whether the Unity guys have seen this, and whether there is a version of Unity 5 that has dealt with these issues?

I've been trying to narrow it down using Crittercism data, and all I see is that most occur on modern Samsung devices (SM-G9xx series). I have seen the thread about Adreno devices, but many non-Adreno devices show this problem as well.

I have not been able to locally reproduce it, but appreciate any help.
Thanks,
Jimmy.

 

Have you tried Unity 5.3.1p2? because there been many Android fixes and updates.
I would think taking a chance on this version is better option than downgrade to 4.6x

 

We had originally moved to 5.3.0 and moved back because of an audio/GC bug. Currently looking to see if they fixed those issues with latest.

 

I think I've got a similar / the same problem. I've got it occurring on a Samsung Galaxy Note 10.1 (2014).
I stupidly posted a thread in the wrong forum

I should mention, my current crashes are using 5.3.1p1, I'm testing 5.3.1p2 now.

 

Submited Case 759386

 

It still crashes on Unity 5.3.1p2.

Does anyone know how to debug this? I don't understand what to do with these logs?

We tried building our app with 5.3.1p2 to see if this has been fixed, but the same result was obtained - the app crashes in the wild at a rate of 2%-5% while our app built with Unity 4.6 on Android has a crash rate on the order of 0.2-0.3%. We were still unable to reproduce this locally.

 

Is it crashing on Samsung devices? We found that our build now suddenly crashes on our Samsung Galaxy Note and Samsung Galaxy Tab. Any correlation?

 

It crashes on Samsung devices as well as others. Now there is another thread with this crash (their callstack addresses are almost identical, but somehow they have the symbols for that crash):
http://forum.unity3d.com/threads/5-3-1p1-crash-on-andriod-when-loadlevel-or-loadlevelaysnc.380795/

 

Here's our callstack on 5.3.1p2 for comparison:

is it crash when loadlevel ?????

 

How's your findings? Does it get fixed?

 

It's still not been fixed for us. I'm trying 5.3.2p2 today though.

 

Does it only happen when loadScene or LoadSceneAsync?
Or randomly happen ? is it related to memory issue?

 

It appears to be random.
It doesn't happen specifically when loading scenes, though it's difficult to tell as we load a lot of scenes.
It's not a memory issue, we've isolated any of those separately, though we don't get many memory issue any more.

 

So it means it crash randomly even no any user action or loading in programs?
Or you have some constant services behind?

Do you have Unity Ads or Push Notification?
Let's guess it.

 

There are many background services, we have Analytics, Push Notifications, Ad Networks. None of which are Unity's, they're all third party.
The crash has happened both in the middle of events/animations/loading playing out, and while nothing is happening.

Bear in mind this is only on Samsung Galaxy Note 10.1 for us. Nvidia Shield and Nexus 7 both run fine.

 

We have similar random issue in Samsung Galaxy Note 3.
Have you tried to remove one by one - i.e. Analytics/Push Notification/Ads etc.?

 

We haven't yet. We're not in too much of a rush to upgrade at the moment, so digging into this is a low priority.
Removing any of our third party plugins would require a bit of work, and we haven't dedicated any real time to it.

Our build using 5.3.2p2 has so far not crashed. Though it's only been tested for an hour straight so far.

 

Did you find any solution?? I am having the exact same problem as yours and stuck for 2 days.

 

Seems to be linked to / the same as this thread.
Unity 5.3.2p2 fixed the problem for us though.

 

Hi, I SOLVED THE PROBLEM. It was bcoz of the audio Settings which was giving the trouble.

 

Which audio settings?

 

Hey, we are having exactly the same problem,
check out my post here
http://forum.unity3d.com/threads/st...r-signal-11-at-libunity-native-method.386535/

 

Unity 5.3.2p3 still has the crash happening on 5% of our Android users.

 

same problem !!! , In Unity5.3.5P6 the crash happening on 8% on android

I am not able to reproduce this crash in my devices. It is occurring only in android version 4.4. I have googled it and the people saying its a unity bug but unity developers said they have fixed this issue. But i am keep on getting this crash in same devices. I am using Unity 5.4.0 f3. i dont know what to do. Can anyone please help me in this. Thanks.

 

Looks like the same issue i am having (see this thread: https://forum.unity3d.com/threads/u...1-how-to-diagnose-or-fix.441180/#post-2872392)

 

Any update on this issue?
