I totally understand your feeling and you're so considerable. You were totally right, that's the thing we're currently worry about. All of our Android version is too old to catch the trend, and if we want our products to be used for longer time, this must the urgent issue we need to solved as soon as possible. However, I really need to discuss with our engineers from hardware and software team, I think they want to use the latest materials for building the newest version of products, but there must be high cost and long develop time relate issue. I really need to talk to them, sorry about that. Once I got feedback, I will let you know.
I have EXACTLY THE SAME PROBLEM. I used the online update proposed by my Z4 Aurora, and after updating, my preinstalled Youtube is stuck on the same state.
The additional issue is that I can not uninstall this YouTube app, Aptoide refuses when I click on Uninstall.
1. How can/When this bug be solved please ?
2. Is there a way to downgrade to firmware 1.5 ?
I REALLY HOPE that your support engineer will support this Hardware in the months to come, or all initial Z4 bakers may be very furious in the weeks to come !
YOU SHOULD DEFINITELY REMOVE YOUR AD TELLING PEOPLE TO UPGRADE TO FIRMWARE 1.6 FOR THE MOMENT... Waiting for a solution to solve this issue...
BTW, I am very upset on having done this buggy upgrade.
for this issue i tray many scenarios in past few days here they are:
1.reset Z4 to factory setting: every thing come back to work perfect but after 10 to 15 minutes you-tube stop working i face some message before it stop like (time setting error or check time setting- other message appear fast and i can't see it)
2.try uninstall pre-installed you-tube for android TV (v1.2.7) throw Aptoid or any other way and i couldn't achieve it
3.try to upgrade pre-installed you-tube for android TV (v1.2.7) to v1.3.11 or any other version and also it not work even the same version throw apk also not work
4.install you-tube for mobile to use it insisted to pre-installed one and i it told me that i need to upgrade google instance it self first to work
5.also try to install you-tube for android TV from google play store it self and it told me that my device not compatible with the current version
really i'm up set from this annoying issue which is i think has related to current version of android (v4.3) pre-installed on Z4 if your engineer didn't able to solve it or didn't upgrade android it self it will be killing issue for this grate product by the way i can assist you in any test scenarios if you need
After Days of testing for this annoying issue to find a permanent solution for it
FINALLY I GET A SOLUTION FOR IT !!!!!!!!!!
first of all this issue is because when i want to install any new app on Z4 i go to GOOGLE paly store throw (https://play.google.com/store/apps) or throw pre-installed app sotre it's self so after install any app from it youtube stope wrok this give me an idea that when you install any app from GOOGLE store throw web installer or its app GOOGLE may modify or Edit Z4 Google Play Services pre-instaled on it to inforce you to update it to newest version which is for Z4 not supported or cann't do it (for me it give me error when i try to install or update it)
So you can test this issue by install youtube from GOOGLE market (https://play.google.com/store/apps/details?id=com.google.android.youtube&hl=en) and when you tray to use it ,it will tell you that you need first to update (Google Play Services) and not wrok
So if you want to avoid this issue all of you who want install any new app on Z4 download its APK direct or use another store for it,
for me i use (http://en.uptodown.com/android) good store and give you apk's direct to your internal storge.
So here is scenario for make every thing work again:
1.make default factory rest for your Z4 and for first run after reset go to youtube and make sure it work fine.
2.don't install your new apps from GOOGLE play store or its pre-installed app on Z4.
3.don't login to GOOGLE play store throw your Z4 to avoide any collection or modification of (Google Play Services) on Z4 from GOOGLE. (Thanks For ruzgar.ender on YouTube stops working Thread)
4.use APTOIDE,(http://en.uptodown.com/android),download your App APK direct to your Z4 or use any other andoride application store on internet and they are many to avoide any collection or modification of (Google Play Services) on Z4 from GOOGLE.
5.test every thing for couple of days and i hope that you enjoy again with your youtube as me
