App running on iOS 7.0.4 with 64-bit devices : UNSTABLE ?

Hi,

My app Music4Kids is available since last 30th November on the AppStore.

Few users, running on iOS 7.0.4 iPad Retina ( 64-bit ) have problems with my app (black screen just after launch).

Others users with the same configuration don’t have any problem.

It seems to be unstable with 64-bit devices, even if with mine, it works well.

Don’t know what to do for the moment…

Anyone has an idea ?

Help from Corona Staff would be great!

Thanks

Best,

Olivier

Hi @oromanetti,

It does appear to be related to Apple’s new 64-bit A7 processor. We’re hoping Apple fixes this soon in an OS update.

Hi Brent,

thank you for your answer.

So it’s an hardware problem?

iOS 7 has nothing to do with this?

Because some users said that they got black screen with iOS 7.0.4 on iPad 2 or iPhone 4S…

I precise that I tested a lot on these devices with iOS 7.0.4 without any problem.

It’s a big problem for users, even if it seems to happen rarely.

Hi Brent

Do you enabled the 64-bit architecture in corona builds ? Is there a way, like in XCode, to disable it? in config.lua or in build.settings files ?

Thank you for your help

Hi,

we’ve started to receive support tickets regarding black screen after startup from some of our users as well. We have several games out, and the users that report the error gets a black screen on all our Corona built games. It makes no difference if the game is built using a pre-graphics 2.0 or post graphics 2.0 build.

What’s the status on your side, Corona Labs? Our support team receives quite a lot of tickets regarding this, increasing every day.

@haakon, that’s pretty broad error report.  Is this happening on iPhone 5s, and iPad Airs?

Hi,

all the reports so far has been from users with iPad Air and iPad 4.

I have worked all night with one of the users that has this problem providing him with builds where we use Crittercism and the custom error handler in Corona, but even if we initiate Crittercism in the appWillLoadMain delegate no errors are logged in Crittercism. Thus the error happens _before_ main.lua is run, and that means the problem is either with Apple alone, or with Corona + 64-bit hardware.

#12

I’m pretty sure the iPad 4 is 32 bit.  Apple didn’t introduce 64 bit until the iPhone 5s and iPad Air.  Could it be an issue with Crittercisim and iOS 7.

#13

Hi,

no, I added crittercism tonight to see if we can get any crash reports logged. We’re totally lost when we’re not able to reproduce the error. But like I said, it does not log any errors, so the crash happens before the lua runtime loads the main.lua file. Which means there is a bug either in the Corona core or with some Apple devices.
