I keep getting reports from users stating that my app is freezing up. However, I'm not seeing any crash logs/reports related to that bug.
How can I figure out why it's freezing as I don't have access to that users device?
I've tried looking through XCodes crash logs, but there are no crashes.

As the title says, my Unity project keeps crashing whenever I build an app for Android, and I'm not sure what's the cause. The crashes are inconsistent, sometimes it builds, sometimes it crashes. Here is the Unity crash log: https://sharetext.me/6qsszytlzp
I'm using Unity version is 2020.3.38f1 Personal.
I've tried restarting the computer multiple times. I've tried reading the crash log but I am unable to make heads or tails of what its saying.
Do let me know if I'm missing something!
I am building an in-house application. My manager told that my app freezes time to time and she has to restrat the whole iPad to restrat the app. How can I handle these kind of sudden app crashes?

Debug your application using Instruments, that will help you locate why the app freeze.
Besides, if it crashes, you can plug the phone on your Mac and retrieve the Crash Log, then analyze in which method it has crashed. See the documentation.
I have an app in ad-hoc mode and it crash right after starts. I have access to Xcode and i try to find crash log like here: iPhone crash log?
But i have no crash log from this app. Why?
Right after app starts i can see Default.png and few second later it crash, i've never even see the mainViewController. How do get a crashlog? How to detect this error? I don't have an access to source code. I have only ad-hoc distribution.
Problem not occurs on every devices. AFAIK this is only 3GS problem. Strange.
Instead of looking for the crash log, try connecting your phone to xcode but look at the Console screen instead, run the app and you should see output on the console, see if you get an error message there.
For users who don't have access to Xcode or are running on a PC you can download Apple's iPhone Configuration Utility which also gives you access to the device console.
I'm not a developper, but a user of an iPhone (3GS, iOS 4.1, Jailbroken) which started to crash randomly last week on several app. If I'm right, it crashes randomly when I tap on the keyboard (texting, sending an email, search on Google...), so that's why the crash happens on several app I guess.
By crashing I mean:
- Either, the app close itself (Safari.app, Mail.app...)
- Or, the SpringBoard crash and the iPhone go on SafeMode
What I did before it started to crash:
- Weeks ago, I installed a Cydia Tweak to setup a Frecnh Keyboard, tweak I uninstalled after it started to crash, thinking it was because of it, but apparently it wasn't
- I installed a .deb manually with Cydia, everything went well
- I modified the /dpkg/status file in order to prevent Cydia from asking me for an app update, everything went well too (besides some description line which I had to delete)
Here are 2 Crash Log:

=> They talk about UIKit, does anybody know what is wrong and what should I do to fix the crash? I tried to look for on Google, bu I didn't find anything unfortunately...
Thank you very much for your help!

Correct answer:
Get the package "Crashreporter" from Cydia (BigBoss Repo).
For Springboard crashes, you can ignore the warning at first start.
Select the most recent crashlog, wait a moment for the analysis.
The most likely suspect for the crash will be displayed first.
Get rid of that package, and retry.
I have an app that I occasionally receive support emails for that say the app crashed on them and won't open up anymore. It shows 'Default.png' then exits. Even when the app is deleted and reinstalled.
-I get no crash reports or memory issues (as reported by itunes connect using reports from a significant sample size >20k downloads)
-I've confirmed it's not limited to a specific model and not caused by jailbroken devices.
-The app doesn't have external dependencies, so why would reinstalling it not fix the problem?
What kind of problems could cause the crashing to go unreported and be persistent?
If you have an uncaught exception handler, depending on what you have in there, you will not get reports written out the same way, or at all, as if you did not have a handler. This will make iTunes think there is not any crash reports at all. Uncaught exception handlers are commonly added as part of analytics frameworks, or third party notification tools.
While this could answer your question, a more reasonable explanation is that the crashing devices just need a device restart.
I think every app developer with a sizable install base has struggled with an issue like this in the past.
Are you using any sort of analytics package, such as Flurry, that helps you report crashes? We used Flurry with much greater success over Apple - Apple won't start reporting crashes to you until you have many -- and "just a few" is never enough.
Additionally, if it shows the default.png and crashes, take a hard look at your start-up code. Are you setting something in NSUserDefaults, that if, corrupted, could cause the app to crash on startup?
Admittedly it is strange that a delete-and-reinstall doesn't do the trick.
The users aren't reporting the error reports to Apple. The crashes could come from any number of sources.
You could walk a user through the process of digging crash reports directly out of iTunes during the next Sync and email them directly to you.
You could try asking a user to delete the app from the device, reboot their device, then have them install the app again after a fresh reboot.
