Thought I'd start new thread for 4.2.1 Update Discussions, issues and other info

So first thing:

I have found out on 4.2.1 if you do fastboot command
Code:
fastboot -i 0x0b05 getvar all
The "bootloader" "recovery" & "boot" partitions are now in basic format, which means the fastboot format command will no longer work on these partitions as it is not a recognized format in fastboot, I never did try this on 4.1.1 when these partitions where in emmc format but believed it would have worked - anyone confirm this?

Code:
C:\android-sdk\platform-tools>fastboot -i 0x0b05 getvar all
(bootloader) version-bootloader: 1.0
(bootloader) version-baseband: 2.0
(bootloader) version: 0.4
(bootloader) serialno: 
(bootloader) mid: 001
(bootloader) product: Cardhu
(bootloader) secure: yes
(bootloader) unlocked: no
(bootloader) uart-on: yes
(bootloader) partition-size:bootloader: 0x0000000000800000
(bootloader) partition-type:bootloader: basic
(bootloader) partition-size:recovery: 0x0000000000800000
(bootloader) partition-type:recovery: basic
(bootloader) partition-size:boot: 0x0000000000800000
(bootloader) partition-type:boot: basic
(bootloader) partition-size:system: 0x0000000030000000
(bootloader) partition-type:system: ext4
(bootloader) partition-size:cache: 0x000000001ac00000
(bootloader) partition-type:cache: ext4
(bootloader) partition-size:userdata: 0x00000006b3680000
(bootloader) partition-type:userdata: ext4
all:
finished. total time: 0.105s
Not sure what this means as I cannot find any info on basic format & android
Anyone got any info on this?

HDMI worked great on 4.1 and still works great on 4.2. Don't like the black sidebars, but I can live with it. Locked and unrooted.

More info:

Also one thing you might notice with 4.2.1 is that the developer options is now hidden in settings, to un-hide go to settings and click on about tablet and then on build number click 7 times, a count down will appear as you go & then you will have developer options again. :good:

Can you explain what you mean by black sidebars? Some have reported limited resolution for HDMI out on 4.2.1. Since the main reason for my acquisition of this particular tablet was the HDMI out, I don't want to lose what I have on 4.1.1 with an update. This is my main reason for waiting to do the update.

If you use HDMI output for watching movies stay with 4.1.
4.2 update has completely broken HDMI output, it's impossible to have a real fullscreen on a 16:9 TV, now I have black sidebars and for some apps the bottom bar remain always visible, for me it's almost impossible to watch any multimedia on TV with HDMI.
The problem is shared with Nexus 10, I've already posted this link in Q&A forum, but I repost it here hope that it may be helpful:

I've played a 720p movie and it was outputted at 720p to the TV, so in my case the resolution is correct, at least for HD movies. Didn't test with full HD though. The issue is that, as the above poster mentioned, the tablet outputs at a 16:10 ratio, so on a 16:9 TV you'll have black bars on each side of the TV screen. I can also confirm that the bottom bar is visible with almost all apps I've tested. Some people reported some sound output problems (as in no sound at all), but I have none. I've found out that you cannot set the sound volume once you've connected the HDMI cable to the tablet. So, rise the volume on the tablet before connecting the HDMI cable, otherwise it will output at zero volume and you'll have no sound on the TV.

Has anyone noticed that in 4.2 layout mode tablet works noticeably faster than in 4.1 mode?
They seem equally fast in my case. But I also use Nova.
I find it annoying that the Panorama mode of the camera can work only if I start the camera with the tablet in horizontal orientation. If I start it while the camera is held vertically, I'll get only a black screen.

Aside from HDMI my other issues with 4.2 have been
1. Bluetooth audio lag in games still there

2. Bluetooth controllers like PS3 no longer recognized

3. When selecting recent apps the screen goes black instead of just fading when using Multi-picture live wallpaper

Otherwise I really like this update
It feels real smooth after Root and Lagfix.
Games run well nothing like 4.1.1. Stock. Shadowgun runs well even on balanced mode.
I've gotten used to the 4.2 launcher tho I use Apex launcher in Tablet mode to bridge the gap. (Cause who wants to feel like their using a big ass phone right).
It seems like the core I/O has been stepped up I'm not a speed test guy but I think the improvements are noticeable.

Coming from Hydro-7 with Unters Kernel where everything worked does feel like I'm going backwards a bit. The deciding factor for the switch was the hope that bluetooth audio lag in games had been corrected which it isnt. Plus now no PS3 controller support? WTF? but the improvements keep me holding on.

Bottomline: If you use you tablet as a straight up table with no bluetooth or HDMI accessories its great. My hope is that when the kernal is released our amazing devs can fill in the missing pieces maybe from the 4.2.2 update.

A few days later into 4.2.1, I am pretty satisfied with the update. There is an appreciable performance increase (or should I say: smoothness) with switching between applications and the new 'recent apps' menu. I now feel less nervous with using multiple applications, and I do not feel a need for a task manager/killer. I also like the fact that YouTube doesn't forget the position I paused the last video, after I've left it for a while.

The 4.2.1 launcher is a step back, seems to use more screen space (the extra top bar) and less features (the ASUS pop-up panel is missing). I use the previous 4.1.1 style launcher.

With the next update (4.2.2?), which will hopefully iron things out, I am going to do a device reset to start again fresh and maybe get even more performance.

Thanks to ASUS for being good with updates.

system bar lock

Hi!

My issue with this version:
When i use the system bar lock and i want to unlock it i am asked for a password. I'm sure that this never happened at 4.1 and i have no idea where i can set the password. Is this a problem to anyone else?

Considering the current status of ROMs and 4.2.1, is there anything I can do to improve smoothness and response with my tablet on stock 4.2.1, unlocked, rooted? Or do I just need to be patient until some ROMs start filtering through?

Some background first...

I was unlocked and rooted running TWRP and Clean rom. I did a complete system wipe, right down to the internal memory via TWRP and installed the zip straight from asus. I then installed the patched TWRP for 4.2.1, and installed superuser for root.

I have made no changes to the system at all. Everything seems to be running smoother than with 4.1. I must say I'm so glad asus left the old launch/UI in there, i tried the 4.2 UI and HATE it.

I have found only one bug. I used my tablet to type large fields of text into form fields on a webpage for my job. I probably type about 2 hours per day on my TF300t using the dock. I never had the first problem before, but now, if I'm in the stock browser, and I start typing, hit backspace, type some more, and hit backspace a second time, the browser simply disappears, no FC, no anything. I can open it back up, try again, and it will crash again the second type i hit backspace. Happens every single time, 100% repeatable. I have cleared cache, i have rebooted, doesn't mater. And it only happens on this particular website i use for my job. For a workaround, i can use any other browser, chrome, firefox, dolphin, etc, all work fine and don't have this problem. Very very strange.

Tonight, i will test this issue without the keyboard dock and see what happens.

I also experienced this issue on stock 4.2.1 after pressing backspace twice, at the time I was just having a play around with the new update so have not looked into it yet. I also noticed two other issues with stock browser, every now and then when I open the browser and select a text box to type in the dock & on-screen keyboard will just not type - a close & reopen seems to fix this. 2nd issue sometimes after typing and then trying to select text with long press or shift key, I cannot select any text. :confused:

Lagfix for root users. Its free on the market takes a while to do its thing but let it settle for like 5 to 10 mins and u should be able to feel the difference. hope this helps
