ANDROID VERSION USER SIDE TEMPORARY FIX:
EDIT: more research and testing done. Some steps listed below may not be necessary. See (Revised steps) section for changes. Original steps are marked as (Original steps).
(Worked for me for a few days, then issue began again. Repeated steps again and it didn’t work the first several times, and then eventually did. This may not work for you.)
Short version steps to follow:
(Revised steps): It seems that there are only a couple steps you need to follow, and the rest may be unnecessary.
1: Delete all patches by clearing all data and cache for HS. (Also disable notifications for HS before opening HS)
2: open HS and wait for update to finish.
3: update may near finishing or finish and then Hs will freeze. Exit HS and close application, and open again.
4: HS will open regularly, and ask you to sign in. DO NOT sign in. Stay at opening screen while assets download. Assets must finish before signing in.
5: after assets download, log in. Game should now run properly.
It appears that this only fixes the issue this first time you open it, and after that, the game breaks again and you must follow these same steps again. Works multiple times, I’ve got HS to work for the 3rd time since July 1st patch following this method.
(Original Steps):
(This is how I got it to run the first time. Second and third time I used above steps, so some of these steps may be unnecessary).
Clear cache, clear data for HS. Uninstall. Reinstall. BEFORE opening HS, go into your app settings and block notifications from HS, and I suggest every other app as well, or at least ones you get notification from often. BEFORE opening HS, clear ALL notification from your scrollbar, at the top of your phone.
Open HS and get update, keep HS open for entire update, and during asset download in the HS settings in app.
Any notification may cause HS to crash.
If, after update is downloaded, game freezes on or near 0b downloaded, close app. Then, when opening again, it should progress to log in. DO NOT LOG IN YET, wait for asset download to 100% be complete. For me, clicking log in before asset download was finished caused the game to freeze, and I had to restart the steps from the begining.
More detail:
I finally found a series of tricks to get hs to run on mobile.
After lots of experimentation, and deep research on the issues other people were having, I have concluded that at least one of the issues is notifications in the scrollbar of your phone. Any notification will make HS crash, INCLUDING the notification which shows the status of the update. To install the game and make it run, you have to clear all notifications, and then go into hs settings and prevent hs from showing notifications. Otherwise, HS will always give a notification that update is complete/ downloading, because it always checks the status of the newest update before it is installed. So, the update notification itself, which is always present before update install, always pops up before update is installed, which always crashes itself.
It would also be a smart idea to disable app notification from every app on your phone, as it seems any notification in the scrollbar causes HS to disconnect or crash.
This fixed the game FOR ME, and I cannot guarantee it will fix it for you. This is on android, I know others are having same issue on IOS and I cannot confirm that will help for IOS.
I pray Blizzard properly fixes this issue soon. Also if this fixes game for you, I humbly request you nominate me for the Nobel Prize for amount of work and research I’ve done on this issue.
If these steps work for you, and in your ultimate generosity would like to gift me packs or bundle, my main HS battletag is:
