I'm not sure....But,Maybe did you enable any settings that should not enable in the "Developer Options" ? Or maybe in Accessibility?
IDK if this help you,but see also & this : https://www.youtube.com/watch?v=ZdBB2w-2vf8
Perhaps is a software problem... some third-party application? Put the device in "safe mode" for a while and see if it continues or not...

WM6 - Programs Closing

Hi All
I have a wierd problem with my Vodaphone V1605...
Whatever flavour of ROM i upload to it - it keeps doing the following:
If in "closed mode" the programs all keep closing like someone is pressing the "X" button constantly.
If in "OPEN" mode the Start menu keeps opening.
it is almost like someone keeps clicking that part of the screen.
Do you guys think it could be a software issue - I would assume it is a Hardware one ...
Regards
Malcolm

[Q] Red frame around screen when using

What is the red frame around the screen when using any applications it sometimes pops up?
I tried googling this and for an ICS manual but I can't find one, the box had very little in it
Thanks
that should only been seen in the SDK and not on the final device.
are you on the galaxy nexus?
yes I picked it up on the launch day, can I turn it off?
Can you provide a screenshot?

Also could you post a screenshot of your About Phone section, the one that lists Android version number and other information?

U probably got a developer version. Report to xda mods. Their will be hundreds of devs. Ready to buy this developer version of GN.
I'll type it, quicker than trying to find a free screengrabber that works on an unrooted galaxy nexus
Model number
Galaxy Nexus
Android Version
4.0.1
Baseband Version
I9250XXKK1
Kernel Version
3.0.1-ge2433f2
[email protected]#1
Build Number
ITL41D
Power + vol down is native screenshot FYI
But yeah, that's the retail software at least.
Have you been playing around in the developer settings menu?
Theres all sorts of options in there that do funky things. Go in there and see if there's anything ticked that shouldn't be.
Thanks for that,
Looks like it must have been 'Strict Mode' I've disabled it so hopefully it won't happen again.
I didn't enable this unless I did it accidentally.
Its something like flash screen when apps do long operation. Under development part in settings.
Not sure why this would have set to on from new though. Weird..
Just got my nexus and same thing. Thankfully google found this thread it was driving me mad.
Should developer tools be there at all?
Discovered my phone is also network unlocked despite coming free from ny carrier. Possibly could it be i also recieved a developer handset?
4.0.1 has quite a few bugs left to address too. But otherwise nice phone indeed.
From memory this is a way of displaying misbehaving applications for developers.
It's possible you've accidentally enabled it.

^ only got mine yesterday. It came with that enabled by default. Never touched any options in developer tools other than to disable that after reading the thread.
Red frame for ICS
Hi
Do i need to restart the OS after unchecking the strict mode options?
I still got the red frame after unchecking the option.

Notifications disappearing (messaging apps)

Hello everybody,
I got a strange problem occuring only in a certain situation. In order to explain better, have a concrete example here:
I write a message in Whatsapp or Threema. Then I lock the phone by closing the flip cover: The screen then shows the clock from "Asus Flip Cover" and turns off after 5 seconds. So far so good. Now: When I get a message, I hear the notification sound. I open the flip cover and... the notification immediately disappears. So sometimes I miss important messanges, just because of this bug.
At first I thought that it is a third party app that is responsible for this strange behaviour. But yesterday I did a reset of the entire phone via the settings app and didn't even use a backup to restore it. The bug reappeared.
Apparently nobody else is encountering this bug, so before sending the phone back I thought that maybe someone has an idea or even solution for me. The phone is the ZE551ML (not rooted or unlocked) and yesterday I also installed the new firmware (.59); the bug was there since I got the phone, but as I said: I thought it is a third party app that is responsible for this behaviour and I had no time to reset it earlier because of exams and stuff... Is there another way to reset the phone? Maybe a better one than the one over the settings app?
Sincerely,
Christophe
Is autostart denying these apps from automatically starting? By default it denies all apps. D'you have smart-saving mode on with extend standby or the option that turns off data when screen is off?
Is your lockscreen set to show notifications?

WhatsApp and Threema are both allowed to auto-start. I remember that I had to set both of them to "allow".

The following are my settings under "Settings" -> "Sound & notification":
When device is locked: Show all notification content
App notifications: Threema and Whatsapp have no special settings
Apply Material Design: OFF
Notification access: ASUS Launcher
I'm sorry you're experiencing this. I'm tagging ASUS employee @Tuanies hopefully he can provide further assistance. I'm out of ideas since you have already factory reset the phone.
Does this happen if you disable the flip cover features?

You mean turning the entire Asus Cover View off? I just tried and the messages still disappear. Actually the screen turns on automatically, the lockscreen appears and they disappear within a second.
After the reset I even got the strange behaviour that messages arrive, sometimes, late or only when I open the specific app.
Do you have any notification filters set?

No.
Just tell me if you think the problem is hardware related or software related. Personally I wouldn't say it is hardware related but one may never know for sure.
I know the firmware from ASUS is quite buggy (and has a lot of translation faults btw.) and, according to some research on the internet, ASUS often tries to break the law by not repearing rooted devices even if it is entirely legal in the EU. So before unlocking the bootloader and trying an alternative firmware, I just want to be sure.

Sounds like a software problem, does it happen right after a wipe without anything else installed? Could just be an installed app causing issues.

What do you mean by "wipe"? Do you mean booting into recovery? As is mentionned above I did a reset via the settings of the phone. After this reset I only installed Threema and Whatsapp and the problem appeared again.
Does it happen before those two apps are installed?

How should I know? The problem appears with messaging apps, so I can't test it without them.
a possible answer
I think I had the same problem after arbitrarily swiping or tapping the wrong response to use CM lock for Asus with the latest updated.
Google "Lock apps" function integrated with CM AppLock" to navigate to a possible hidden app setting preventing you from seeing notifications and uncheck "Hide notifcations... " under the "Options" heading on said page.
shortcut:
(App Drawer settings, lock apps, input pattern you chose, settings (upper right 3 dots), uncheck "Hide notification")
I now have all my notifications back that I allowed in other settings.
I hope this helps.

Problems with Android Wear

Hello everyone,
I have some problems with android wear. I’m not getting notifications on my watch and there is a message in the home of android wear that says "Notification stopped syncing". It happens sometimes, not always. What can I do? I tried to reset my phone, my smartwatch, the android wear app and moto connect but nothing is changed.
ps. I turned off doze for this app.
I have a Moto 360 and it works fine with m'y OP3
I found the problem. I noticed that it happens when I tap the "clean" button in multitasking. After this the only way to solve that problem is to turn off the device and turn it on again. So if someone is making a rom please solve this problem!

Thx had the same problem. Thought it was something with battery optimalisation.
You can lock the AndroidWear app in the multitasking screen by clicking on the lock button on the top right.

the "clean" function clears all apps/services/etc from RAM which is something that never needs to be done on Android.
The problem isn't with android wear, it's just a function which shouldn't be included in the ROM at all - don't use clean and youll be fine.

Question Touch Screen Problem!

hello everyone,
I just bought z fold 3 a few days ago,
after hours of working with I found that sometimes the touch screen(inner display) doesn't respond,
for example, some words don't type when I am typing quickly with the keyboard (just sometimes)
factory data reset didn't help.
has anyone run into the same problem? may be resolved with future updates?
Is it only happening to apps connected to the internet ie is it a connection issue?
The internet's been goofed up in some areas the last few days. Try toggling the airplane mode off/on.
Keep power management disabled for now.
Does it happen in safe mode?
Find the factory test settings for the touch display, test (and calibrate if needed/possible).
If you can't resolve it, return it. Otherwise eyeball every square inch of it like a hawk...
I tested the touchscreen with *#0*# and everything is fine.
just sometimes this problem occurs and I think this may be software problems...
have you z fold 3?

No. Basic troubleshooting.
Samsung will likely release firmware updates to correct this if enough devices are effected. It may be a 3rd party app causing this... try in safe mode. Disable animations for now and see what its got.
I stopped at the N10+/Android 10 and will likely stay in this holding pattern for at least 2 years.
I have two now and they run close to flawlessly.
Both Samsung and Android are having major issues, plus I require a SD card slot. Even issues on the N20U, which helped nix it from my list.
It may be a good year for Fold fans but otherwise both Android and Samsung have dropped the ball and are in a flat spin... in my opinion.
my problem is just like what you see in this youtube video in Time 12:15 and 12:49 . I must double try some times to click some things. this is very annoying on the keyboard and when you are typing quickly.

If stateside you can go to a Best Buy that has a Samsung Experience store. They can do advanced testing on it... allegedly.
I would get it resolved soon or return it for a complete refund.

I tested the touch screen with "touch screen test" Application and uploaded a video on youtube, you can see here.
It looks fine to me... do you mean latency time?
What are power settings at? Try bumping it up to maximum performance.
Check ram usage.
Is there anyone here with z fold 3 and the same problem?!!!
I only face this problem when I touch the edge of the display with my palm.

I tried to replicate the issue. I downloaded the same app on my Fold 3. I tried for few minutes.
On my device every click is registered. No missing dots.
I have the exact same issue. I addressed it by increasing the screen sensitivity.
Hey, I just noticed it today as well. When I try to type text faster, sometimes I need to double click on letters. I think this problem came with the latest update, because I havent had that problem before. It is frustrating.
I tried to turn on sensitivity option in settings and I will reply here after day or two testing.
seems to be a bit better with that option turned on
