[Issue]: Main screen does not respond to touch

[IAJaay]

Issue Description

Device: Samsung Flip Z 3
When issue happens: Seemingly randomly. I was able to get the issue to pop up after I opened Angry birds 2 in tooui app and then flipped the phone open to the main screen. Does not happen every time though.
What happens: After "unflipping" the phone so I can use the main screen and unlocking the phone the main screen(not the cover screen) does not respond to any touch whatsoever. Only things that work are side buttons and swipe gesture at least from the top. After rebooting the phone everything works normally.
When the issue started happening: Sometime during march - april.

Another issue popped up after opening the flipped phone to the mainscreen when angry birds 2 opened from the tooui app.

Guide Confirmation

• I have reviewed the guide and included valid logcat content

[AbandonedCart]

The app runs on the cover screen specifically. Whatever is blocking touch is not shown in the logs, but there is no reason to think it would be this app. I would need something a little more concrete to go chasing that.

[IAJaay]

Okay. I´ve set double tap on side button so I can access tooui app in case of this issue happens.
I´ll try to disable tooui app from the apps main switch next time and see if the issue goes away. That way we can see if the app is the culprit.

[IAJaay]

I think I can reproduce this now. Already succeeded thrice with the following:
a) Open 'Angry Birds 2' app in the tooui gridview.
b) Wait for app to open to its main menu
c) With the app still open on cover screen .. slide from bottom and press tooui-button(the middle on with person in it) -> tooui:s app-grid is shown
d) Open the flipped z flip 3 so you can see the main screen. -> phone wont respond to any touch gesture anymore on the main screen

If the above does not work for some reason, please try to delete app data to defaults and reboot the phone and then try again.

I hope this helps

So the issue is Angry Birds?

Does it still happen if you close the launcher before opening the screen? Forcing it closed would be the only real option that doesn't have the side effect of limiting functionality.

[IAJaay]

The problem is not the Angry Birds app itself it seems.
You can launch any app and the issue still occurs.
If by closing the launcher you mean double tapping the icon as mentioned in the guide, that did not help with the issue.

[AbandonedCart]

You said you open the drawer before opening the phone. I'm talking about closing the drawer.

Since I can't replicate the issue and it's not showing up as an error, the next best thing is trying to come up with a solution that can then be automated.

[IAJaay]

I tried following for closing the drawer:
I pressed the gray area at the bottom when app-grid is shown and then press the right side icon with 'hand picture and arrow down' and get the default screen showing date&time or whatever. -> did not help with the issue.

However I noticed if after step d i go back to cover screen and open the same app from the app-grid again and then when app is open I go back to the mainscreen , then the main screen responds to touch again. However if I open another app than the first one then I do not gain control on the main screen. Only if it is the first app launched from app-drawer it seems.

The steps to gain back the control of main screen:
a) Open any app in the tooui gridview.
b) Wait for app to open to its main menu
c) With the app still open on cover screen .. slide from bottom and press tooui-button(the middle on with person in it) -> tooui:s app-grid is shown
d) Open the flipped z flip 3 so you can see the main screen. -> phone wont respond to any touch gesture anymore on the main screen
e) go back to cover screen and open the same app you opened in step a so that app is shown on the cover screen
f) go to main screen again --> main screen responds to touch again.

However if as step e:
e) go back to cover screen and open another app than you opened in first time at step a
f) go back to main screen -> main screen does not respond to touch.
to fix this I have to go back to cover screen and launch app that I launched at step a again so that it is shown on the coverscreen -> then I get the control back on the main screen.

I also made another logcat of the steps a-d mentioned and noticed error I think is missing from the earlier:

dunno if this helps at all but heres the whole logcat:

I´ll try to delete app data and see if I can still reproduce the error. It is quite odd that it occurs only with my settings.

[IAJaay]

Tried with factory settings and issue still happens.

When I tried to enable accessibility there should have been 'Samsprung Navigation' under Installed apps - as the text says but I cannot find it, thus accessibility might not be enabled.

[AbandonedCart]

You have the Google Play version, so there are not accessibility options. Google Play does not allow that.

I'm still unable to duplicate your issue. I don't lose touch at any point, whether I open the screen while the app is launched, while the launcher is open, etc.

[IAJaay]

I also tried with github version but still the same problem. Wasnt still able to enable accessibility due missing instructions from Samsungs side how to enable since 'Samsprung Navigation' was greyed out ... so I installed google play version again.

I´m quite out of ideas how to hunt this bug anymore. Do you have any hunch what could cause such behaviour if it is something in The phones configuration or something? The phone is not rooted or anything so cannot suspect anything there either.

[AbandonedCart]

This is honestly the first time i've encountered such an issue. It sounds similar to the way the cover screen blocks touch when the launcher is running, but the launcher specifically runs on the cover. The only thing I can think of would be that something in the way you are trying to open the launcher and then the screen is causing it to launch that as a normal app. I can try adding a filter that won't allow it, but nothing can truly prevent someone from breaking past it if they try hard enough.

[IAJaay]

I noticed that I can navigate to the app in mainscreen and then regain touch on the mainscreen more easily so I do not have to open cover screen again. Makes this issue much more tolerable.

Edit: Didnt help later on in normal use. I´ll try to live with this and see if I can avoid whatever way of use causes this.
