MM Shows a plain Black Screen on iOS 9.3.5 device

Pipe-line

@idoodler thanks! I will try develop branch this night :)

I also identified the issue. It is related to the use of Promises, a feature of ECMAScript 6, which is not supported by iOS 9.3.5. The feature is used in multiple javascript files that are built into the core of MagicMirror2. I believe it can be fixed with a polyfill.

idoodler

@thobach I don‘t think its an issue with the promise itself, but rather with the arrow (=>) operator that defines the callback.

thobach

@idoodler True! It was fixed in https://github.com/MichMich/MagicMirror/commit/6bb4db38428af7ac46a6f4240ab9cfe4bf9fcbea and I can load now the default configuration on iOS 9.3.5 again.

But I can still find one use of “=>” in the develop branch: https://github.com/MichMich/MagicMirror/blob/fb0cc61e09542533affa92b1e8bd6f9a2aca6363/js/module.js#L84.

@thobach that link you posted points me to a specific commit. I can not find any use of the => operator in the browser part In remote/develop

@idoodler so just to clarify, this has been found and due to be fixed?
or did i totally misread that…

if so can’t wait for new release!

EDIT: pardon my manners, thank you for checking this out as well :)

idoodler

@shiroe This issue has already been fixed on the active development branch. Its basically ready and will be available on the next release.

You can already test this fix by switching to the develop branch, but be carefull, this branch is still under active development, hence the name;)

shiroe

@idoodler thank you very much again, will keep an eager eye out for this one!

I had also an issue with the default calendar module on an iOS 9.3.5 iPad. It could not be rendered. On debugging the iPad Safari with my MacBook i found the reason here: modules/default/calendar/calendar.js, Line 439.

for(let evt of eventList){

should be

for(var evt of eventList){

so that older browsers can render the module without error. Would be great if you can add that for the next release :folded_hands:

Force close the app. Then upgrade your app may solve iPad screen black problem.

This is still an issue.

I have MM 2.12.0 and an iPad2 running 9.3.6 (the highest it will update to). The iPad2 gets the black screen when I go to MM http://ip-address:8080. My iphone 7 renders the page perfectly as do all of my Mac and PC laptops. I had an issue on an older laptop but updated the browser and that fixed it. I can’t update the browser on the iPad as the newer versions need iOS 10+. Any suggestions? Thanks!!

@spoonek did u try chrome browser on the iPad?

spoonek

@sdetweil Yes, that is my default browser. I tried Safari as well, no luck. I then tried to install Firefox and got the same issue, needs version 10+. Thanks!! :clinking_beer_mugs:

sdetweil

@spoonek if u have the black screen using chrome, open the dev window (see the menu) and select the console tab and scroll up to see any errors

I guess this is the problem of iOS.
Have you tried to update the iOS and the app? May be these will help:
1.Update the iOS and the app to the latest version
2. Force Restart iPhone to Fix iPhone
3. Use iOS System Recovery to [fix iOS system free for mac](link url=“https://www.tuneskit.com/ios-system-recovery-for-mac.html”)
4. Using iTunes to Fix

Any news here for a workaround? Tried it with my iPad 2 (9.3.6) and different browsers… also installed the developer branch on my server.

sdetweil

@magicx no, and it will be harder in 2.15, as more code has been converted to es6 notation which the early ios browsers don’t support
