Crash on Samsung Galaxy Note II

Unity Engine
,
1

I apologize in advance if this is in the wrong forum section.

We have an Android app that runs fine on most devices, but is particularly having trouble on the Galaxy Note II. The crash logs boil it down to a problem with the Mali GPU or its libraries. We’ve also received reports of crashes on other Mali GPU devices, so this issue may pertain to those as well. One hypothesis is the latest Unity update: prior to updating Unity from 4.1 to 4.2.1, the Note II performed fine. However it could also possibly be graphics optimizations on our end.

Another oddity is that the crash doesn’t occur if Development Build is checked in the build settings. This produced a lot of extra logs, but none around where the crash would occur.

Below is the crash log from the Galaxy Note II. Any insight would be tremendously appreciated!

Since it is an OpenGL driver related crash, I would report it to Unity with small project that can be used to replicate the issue
http://unity3d.com/BugReportingFAQ

Other option is to figure out what kind of call actually crashes the app (e.g. drawing with certain shader) and try to tinker some sort of workaround for it.

3

Hello, I’m having exactly the same problem but with a samsung galaxy s2. I don’t post the log because it is really similar to yours. In other devices the game works fine. I can reproduce the bug and the crash doesn’t occur if Development Build is checked. I can confirm that in the version 4.2.0f4 also happens, I could not test earlier versions.

4

Thanks. I have submitted a bug report to Unity with the log in my OP.

After further investigation I noticed that I wasn’t using mobile shaders everywhere that I could, so I swapped some of those. On a fresh install the app ran fine, but after force closing and re-opening, it crashed every time.

I’ll keep this thread up to date with my findings and any responses I get from Unity.

5

That sounds like a bug in the shader cache. Can you try clearing the cache on game start too see if that helps? Put Handheld.ClearShaderCache(); into a script that is loaded before the scene that is causing the crash. If that works at least we know where to start digging.

6

Thanks for all your responses. I’ve found a solution, however I still don’t know the root cause. I will post my findings in case anyone else has a similar issue.

I’m using NGUI in this project. I have a loading screen with a “Loading” label over an animated bar, plus another label for tooltips that pull from a random string table. When I set the tooltip label’s text to the random string, it causes a crash. Specifically, the following line caused the crash.

tooltipLabel.text = str;

I suspected the issue was in indexing the table of strings, but that wasn’t the case. I could still cache the string and simply not set it to the label’s text and the game would run fine. Even hardcoding the label’s text to an arbitrary value was fine.

My next suspect was the label object itself. Perhaps the engine considered it “dirty” in the meta somewhere, so I created a new label with NGUI’s widget tool, but the crash still occurred. Next I tried using the “Loading” label over the loading bar on a whim, and that worked. So I duplicated that label as the tooltip label and it’s been running smooth ever since.

I have no guesses as to why certain NGUI widgets cause crashes in the graphics driver on this specific device, but here’s a workaround at least.

EDIT: I’ll go ahead and include more info on the device and software versions involved.

Has there been any development on this problem?

We have noticed that after our game’s release we are seeing a similar problem on these devices. We’re currently scrambling to get things patched up ASAP since customers are starting to give us negative reviews on the store.

Here’s a list of some of the effected devices reported by Google Play:
-Samsung Galaxy S3
-Samsung Galaxy Note 2
-Samsung Galaxy S3 Mini
-Asus Memo Pad ME172V
-Tesco Hudl HT7S3

Something I have noticed that all these devices have in common is that they are using the Mali-400 GPU

Is it possible that this is a driver bug, and if so how can we avoid it?

8

We have the same problem and crash in the same location. Also we’re using NGUI too. But our codebase quite “fat” and it’s very hard to isolate something. also it happens after about 1 hour of game in some particular way - so it’s quite hardly to reproduce.

Device - Samsung Galaxy S3
Unity - 4.1.5

9

I’ve found strange workaround - disabled Dynamic batching - crash disappearead and fps slightly increased.

10

We have recently had to split a project with iOS running Unity4.3 (for crash fixes) and 4.2 for android (vuforia on android doesn’t work in unity 4.3).

We have since noticed a similar issue. A crash during our AR scene when you get too close to the items in the scene. From what i can tell the logcat output also points to Mali related libraries. Much like the OP this crash also disappears when we check the Developer build flag in the build settings.

We’re testing on a Samsung Galaxy S2 and a Nexus 10.

Turning off dynamic batching didn’t yield any changes. We do use almost exclusively custom shaders in the scene though So will attempt to try the shader cache fix, and check any shaders for possible optimizations (wouldn’t surprise me as a previous crash occurred if on android i changed the alpha channel of the tint colour on the shader during the fragment shader). I’ll post any additional information if either of these works.

Anybody else have any new information or other potential fixes for this issue?

11

According to Unity Issue Tracker, the issue is supposed to be fixed (Unity Issue Tracker - Crash with Fatal signal 11 (SIGSEGV) when loading scene asynchronously), alas the fix doesn’t appear to be present in 4.3.1 :frowning:

12

Please does anybody know if this issue has been solved in 4.3.1 ?

Thanks

13

I guess not. I encounter the same problem. I tried both 4.3.1 and 4.3.2. The app crash problem still exists.

14

We just received this crash report from our client, reproduce on:
Samsung Galaxy Note II GT-N7102
Samsung Galaxy S III GT-I9300

Which cant reproduce on:
Nexus 4
Nexus 5
Nexus 7

Unity version: 4.3.1f1 Pro

Our game crashed during loading our lobby scene which contains a lot of NGUI and Awake() scripts. The interesting thing is loading scene with no complex scripts works fine. Even this scene contains a lot of complex shader, big textures and high number polygons.

So I don’t think this is a shader or texture related issues. @FatWednesday

15

I’m also having this issue with a Galaxy Note 3. The menu loads fine but once I go into the game scene I get an instant crash.

16

Same problem here, anything new?

Cheers.

17

Hey Guys, this is a serious problem here, my app crashes on every MALI-400 device… there is no official word regarding this?

Cheers.

18

Not that I heard of, are you using latest version of Unity? If yes, submit a bug report with a project attached and send me it’s number.

19

mmm, I can’t send my project due to NDA, and also since I don’t know from where does this problem come I can’t reproduce it, I’ll try to reduce the project so I can reproduce the problem, but since I don’t have any device with MALI 400 I can’t properly test it either.

Anyway, you can find an error report here:

And it is clearly related to the MALI-400, I don’t have anything weird in my GUI inside the script defined as problematic in that report, and I even tested disabling all the GUI options and it crashed also.

Cheers.

A bit late to the party but we’ve just been burnt by this problem on our game, Race Team Manager. The underlying problem seems to be a bug in the device driver for the Mali-400MP GPU that was introduced around Android 4.2 – we had a Samsung Galaxy Note II on Android 4.1.2 and the game ran fine, absolutely no problem. When we started hearing of crashes in the wild we upgraded that device to Android 4.4.2 and sure it enough it was crashing a lot with a call stack very similar to the above. Our current thinking is that it’s related to this bug that ARM have acknowledged:

http://community.arm.com/thread/5778

Fortunately we were able to figure out a workaround. The crash only manifested itself during vehicle rendering and the thing that stood out was our heavy use of sub-meshes in the vehicle models. At the driver level this means there is a single, large vertex buffer and multiple smaller index buffers that use it to draw their meshes – many index buffers to one vertex buffer. By changing the vehicle build pipeline to avoid sub-meshes the problem went away – in this case there is a one-to-one mapping between vertex buffers and index buffers and the state management within the driver is different (probably less efficient, unfortunately, but at least it doesn’t crash).

So, if you’re suffering at the hands of this problem (which is definitely not a bug in Unity) it is recommended that you find any models with multiple sub-meshes and re-export them to avoid this. Models with sub-meshes are easy to spot because the Mesh Renderer component will have multiple materials.

Hope this helps somebody – it took a lot of tracking down.
