Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Howdy bethor,

Thank you for reporting this issue. I have just attempted a quick repro of this issue internally and have been unsuccessful so far. Here are the steps that i took:

1) Deployed a template project to a Shield Tablet on 2.2.1 2) Once deployed, I opened the console command in the level and entered 'profilegpu' 3) I was unable to see any errors on the device.

Would there be any steps that I would be missing? Any additional information would be greatly appreciated.

Thanks and have a great day!

Hello Sean,

That is strange. Just in case I tried making a clean sync and build on a different pc, and see the issue there too.

Some possible areas of mismatch I can think of:

  • Are you building from the release branch (not master)?

  • Are you using a Development build?

  • Are you entering the "profilegpu" command directly on the device, after bringing the console up with a 4 finger tap?

  • Are you checking for errors in logcat (there is no dialog box)

  • Does your shield tablet version details match the following:

I've also put a test apk built on my machine here:


If you can try this, it should tell us if the mismatch is on the build itself or the device's behavior.

Thanks for looking into this.

Sean, I cannot reproduce the issue on the master branch, so I suppose I just need to wait for the 4.8 release. Feel free to close this issue, thanks!

I faced the similar problem, but I received no crash log. I was using the UE4.19.

Howdy bethor,

Glad to hear that this issue has been resolved for you in the Master branch of UE4. If you run across this issue in a future build, be sure to reopen this issue so that I may be able to further investigate.

Also, just a reminder that the Master branch is not a stable build of UE4. Be cautious when developing a project in that build. I would recommend opening a copy of your project so that you will have a back up if anything does go wrong.

Thanks and have a great day!
