Roebeet,

I have noticed that the sound is quite low on VEGAn. There also seems to be some correlation to the amount of time the system is running and the amount of bugs that show up. I used the Beta 3 since it came out and the first few days I didn't see any errors but now I am getting reboots that happen each time I watch a Hulu video for about 4 minutes. I have also noticed that Angry Birds will crash and then will disappear from the program menu until I restart the system.

Is there a part of the system that may become corrupt over time? Possibly there are some permissions that are not set correctly that are allowing a file to be modified that shouldn't.

Keep up the great work and I am sure you guys will find the issues.

You are lucky I suppose :)
[G Tablet Android Development] bblackmoor:
How do you make it sleep? Will it last all night unplugged without dying if it's asleep?
[G Tablet Android Development] rob_z11:
Looking forward for louder sound and some hack to fix the wakeup bug.
[G Tablet Android Development] rob_z11:
Yes, you hit the power button or let it timeout, and you have taskkiller which runs, and kill all the process.

I wonder if my taskkiller may be causing the slowdown when it wake up?
[G Tablet Android Development] rothnic:
If you are referring to the slowdown at wakeup, that is something that I had addressed through a hack when using zpad. I found that the cpu speed I had no problems with. The slowdown seemed to occur when it woke up, got wifi, then started syncing everything.

I found that if you install autostarts, and disable all instances of the calendar services, the slowdown didn't occur. However, I have yet to experience the slowdown with Vegan.

Before doing the hack I suggest doing a full nvflash restore to stock, then start from scratch going to Vegan. I am worried people are having some data left over from the other ROMs, because not everyone is having that issue.

[G Tablet Android Development] roebeet:
x2. Whenever you move between mods, it really is best to wipe the user data. The init scripts expect certain things to be in /data and using another mod's /data setup might cause weird issues.

/data is like your Windows user profile. Moving between mods is akin to moving between Windows versions - and not wiping /data is like copying an XP user profile directly on a Vista OS, without modification. :O
[G Tablet Android Development] gotwillk:
the OC widget actually made things worse for me. i uninstalled it completely and its much better now. haven't had any slowdown. however, i was able to recreate the slowdown by switching the brightness level a bunch of times through the Power Control widget.

i was switching the brightness around to see which i liked best. i think i must've pressed that thing about 5 or 6 times in a row and then all of sudden, everything became really laggy. i was pressing it fast too, maybe about a second or two between each press. had to reboot to get it back to normal. i recreated this 3 times now.
[G Tablet Android Development] roebeet:
This is the type of stuff i like - helps as far as trying to replicate. Thanks!

EDIT: I just tried this twice, and no issues. But also keep in mind that I'm on a prototype beta 4 with a lot of differences (so that might be a good thing, I hope).

robeet ur the man
[G Tablet Android Development] rob_z11:
I was on TNT, and did full data wipe before moving to Alpha and now beta3. I have always done full wipe everytime I have upgraded the ROM. I am going to look into the Calendar Services, but don't know why since all my google email and corporate exchange account are set for manual sync.

From my HTC EVO, I have learned to disable all sync functions including email, calendar and weather. Nothing gets out of my tablet or phone unless I want to.

I have to look into calendar service and autostarts. I may have to see if my TaskManager will also kill my calendar once it goes to sleep.

Thanks for the info.

It is actually upnplay

Oops.. Nevermind, I see you got your answer..
[G Tablet Android Development] rcgabriel:
I'm on beta 3 and I just jammed on power control widget's brightness switch a bunch of times as described.

I did it every second, every two seconds, twice a second and even 3-4 times a second. Each time I did 5-10 presses of it. I was able to only very momentarily get any sort of lag when I jammed it extremely quickly. Didn't stick my tablet in a laggy mode at all.
[G Tablet Android Development] rob_z11:
do you have a sample autostart script that you can share please?
[G Tablet Android Development] case-sensitive:
Last night I had a similar crash. I'm on vega beta 3, playing with the default clock app. Inside this app you can view pictures and listen to audio, and I was switching back and forth between the two, and within the audio option, changing from tracks to tracks very quickly. Within a minute or two the screen turned black -- the screen was still on (I could see faint light if I turned off all light), but none of the soft buttons were working, and I could not turn off/reboot the gtab (I tried quick tap on the power button/long tap/power button + voume up/etc).

After 20 minutes I gave up, took off the back panel and push the reset button. The gtab rebooted, but was sluggished, so I wiped everything (but not reinstalled the vega) and it's been running fine since then.

To the genius at Viewsonic: why bother having a reset button if the users can't access it?
[G Tablet Android Development] P_6:
I'm strongly considering drilling a small pin hole for just that task.
[G Tablet Android Development] roebeet:
I am fairly convinced that the SD partition (/data, specifically) becomes corrupt at some point. It would explain a lot of the bizarre issues we've had.

I just wiped my SD partition for the 3rd time, since I've owned the device.
[G Tablet Android Development] rothnic:
Sorry, I wasn't very clear. Autostarts is a cheap app that you can get from market that allows you to disable services before they are started.

People tend to use auto task killers, which are not the way to go. The problem is there can be a number of events that cause a service to run. So if you kill it, then it might just start up automatically for another event, then it is killed, and so on using the battery up.

Autostarts allows you to disable a program for starting up on specific events. We used this a lot on the Droid X when it first came out to disable a bunch of their extra crap they had loaded on it without needing to really remove it.
[G Tablet Android Development] vsc:
Is this with all distributions (TnTLite, VEGAn, etc), or just one?

I decided VEGAn has this issue, but I don't have enough experience with TnTLite yet.
[G Tablet Android Development] rob_z11:
Is there a link for this apps? One I found requires small shell script which it calls to enable/disable the apps.

Latest Viewsonic g Tablet VEGAn beta 3 thoughts

It has been running very good for me since it was first posted.

Key to clean running from my perspective:

1. Partion SD 2048/256

2. Data wipe

3. Cache wipe.

I have see one or two dim black screens. After running Hulu hack. reboot things are fine.

My one area that is lacking is video playback. This thing is great on youtube HQ but other formats are picky Cars h.264 trailer does not play well. Only Rockplayer even comes close. Now here is the issue...

From Viewsonic website spec of g Tablet.

S1080p H.264/H.263/ VC-1/MPEG-2/4/WMV9/DiVX 4/5 Video Decode, 1080p H.264/MPEG-4 Video Encode, Supports multi-standard audio formats, including AAC, AMR, WMA, and MP3

Come on, none of this works out of the box or with VEGAn with any consistancy. These specs look good on paper...

Would some out there who have had success with video please write a concise overview of how it can be done cleanly?

This device is almost perfect and has the H/W specs but may be missing codec support... I am hanging on for the great solution Roebeet and crew. Thanks again!

what is this hulu hack that you speak of?

+1 ;)

[G Tablet Android Development] n2thecloud:
You know how you go down the rabbit trail and find goodies and apply all the changes and "sometimes" it works... Well that is what I did from this forum... I see if I can track down the links. The way its done is this in a nutshell

1. Get a hex edited version of latest flash that changes from a android to win profile.

2. Use Ad free but "revert" back so Hulu can still play ads.

3 Do this in Dolphin HD and change the user agent to desktop.

It works at times but is still a bit strange.

Now why would hulu want to stop people on android mobile from watching ad supported TV?

That really is a lot of work... I don't get the reasons...

Search for Hulu and flash in the forum. Hope that helps you with some bread crumbs!!!

"this is the Hulu hack that I speak of" :) :) :)

First bread crumb...

[G Tablet Android Development] roebeet:
I believe so. I suspect that it just has to do with how the device it setup and how /data gets mounted. Granted, I am a bad example given that I use my device a little differently than most people.
[G Tablet Android Development] short/y:
You've ONLY cleared/formatted /data 3 times? Man, I've formatted it every time I've changed ROMs (I don't mean upgraded from one TnT Lite to another, I mean when I've gone from CM6 to TnT Lite to VEGAn). As far as the data that gets mounted on /sdcard, I've never wiped that. Nor have I ever repartitioned. Maybe I'm lucky, maybe it's because I don't leave my tablet on for more than about 8 hours (yes, I actually power it down) or maybe there's a design flaw/hardware bug that is the reason Viewsonic's "recalled" the tablets from Staples.

EDIT: Gee, now that I've publically posted that I've had no problems, I imagine I've picqued Murphy's interest.
[G Tablet Android Development] raydog153:
Mine got corupted, I think it was due to me shutting the device down by holding the power button for 10 seconds, instead of using the power off menu that pops up, but not sure, since then I always try to power down gracefully.
[G Tablet Android Development] n2thecloud:
I am starting to think this power down issue is related to the way I also shut down. During the day I just tap the power button to turn off screen, but every night I try to power off through the menu.

I have also had very few issues that way.

Of course during the rare time it crashes I walk upstairs and frisbee the device out the second story window into the street and let the dog bring it back...it works every time! Try THAT with an iPAD! :)

This is officially called "The Frisbee reboot \etc\fetch" I saw it somewhere in another forum I think :)
[G Tablet Android Development] rob_z11:
If I understand correctly, when you do data wipe, you are actually formatting the /data partition of the 16 Gb SD card, but you are not actually formating the entire SD Card?

I suppose I am using the default size what Viewsonic came with it since I have not repartition my sdcard as others have done it.

Let's say when you repartition SD card using the recovery, you have to have the 2nd SD card to load the ROM since it will format everything, and setup new Filesystem? Is that correct?

I thought wiping out the /data will have the same result since that's where the OS is loading to?
[G Tablet Android Development] gotwillk:
i thought when you wipe data, its wiping the data off the internal storage thats ~1.5GB, not the internal SDCARD. i don't think wiping data touches the sdcard at all.
[G Tablet Android Development] rob_z11:
I thought internal storage is only 512 Mb RAM, and 16 Gb of SD Card that is where filesystem gets created.
[G Tablet Android Development] GTablet:
Whe did Viewsonic recall the tablets from Staples? That is very I purchased mine... when did this announcement come out? Also why are they being recalled?
[G Tablet Android Development] roebeet:
The internal storage is 16GB. Of that, 2GB is partitioned for /data (by default) and the rest is for /sdcard.

When you wipe data, it's erasing that 2GB partition. And, when you re-do the SD card partition, it's deleting / re-adding both /data and /sdcard.
[G Tablet Android Development] GTablet:
Ok, I just taled to the folks at Staples and Viewsonic; there is NO recall on the G Tablet... Staples is doing something internally but there is NO recall in effect!
[G Tablet Android Development] roebeet:
Great to hear! Maybe they are just flashing each device. Although keep in mind that it means that the box is going to have to be opened by them.
[G Tablet Android Development] mcbooth:
Do you think they will flash TnT Lite or VEGAn?? ;)

I looked around on this forum but couldnt find anything.

it says that wifi is using 50% of my battery. and mostly its sleeping.

is there a way to turn off wifi when it is sleeping?
[G Tablet Android Development] roebeet:
If you mean "idle", then nothing tmk. But you can turn it off when the device sleeps (go to Wifi settings, and then "Advanced" menu option. At least we think it works. :O

I personally have a Wifi widget, on my homescreen. If I know I won't be using my WiFi for awhile, I just turn it off.
[G Tablet Android Development] bionaraq:
so I just put vegan on the wifes gtablet. REALLY like this setup. I do have a few questions though. Video. Do I need to get an app for this? Really want it to work with movies on the sdcard (long flight home for Christmas.)

(prior rom was on a Droid Eris...)
[G Tablet Android Development] lamlam01:
It's almost the weekend - roebeet, any chance of a Beta 4 Vegan to play with for the next few days? Thanks for the dev team with their work on this tablet; I am keeping mine. It does everything that I need for it to do on a day to day basis. I have always loved tweaking all my devices so doing this stuff is part of the fun!
[G Tablet Android Development] roebeet:
for MP4's (including supported HiDef ones), the vanilla player works fine. I also use Rockplayer for less-supported containers like MKV.

I've made 10 revisions of Beta 4 in the last two days - I might be getting close to one that sticks. Gojimi also wants to hold off a a bit as he's still working on autobrightness.

The prototype is based on the newer Advent Vega 1.06 image. Audio loudness problems were found and fixed, new Marktet and Maps are there and it's become more modular as TnT Lite is designed. What this means is that the work over the last two days to get it to this point will allow us to drop in newer Vega updates fairly easily. I'm still testing as I want to make sure nothing is borked (found an issue with the speakers today, for example, that took a few hours to fix). All three of us are still working hard to get the next version out!
[G Tablet Android Development] anlog:
I always repartition the SD card between builds, so it's not that. Last night when things slowed down I did a "cat /proc/cpuinfo" and the CPU didn't appear to be clocked down. I think it might be some background app going haywire.

Hoping beta 4 fixes it...

This was my primary excuse for picking up one of these. I replaced an Archie 7 with this and had a lot of difficulty finding an app that would read from the SD card. mvideoplayer works the best you just have to redirect where it looks for installed video to also look in the SD card. It even allows u to put movie posters as icon,s....very nice...and free in the market.

I drilled the hole first thing

Mine locked up, so I took the opportunity to drill a hole over the button while I had the back cover removed.

Looking at the back of the gTablet, measuring with a digital caliper, the measurements are:

76mm from bottom edge, 109.5mm from right edge

For reference, the hole is about 30mm straight down from the bottom of the last letter ("t") of the oval "g tablet" logo.

Check your measurements with a caliper in case there are any production changes from mine.

Don't try to drill the hole without removing the cover. The switch is very close.

All you need is a hole large enough for a paper clip.

You can see the button on the first and fourth photos:

Well I hope I dont get bashed, this thread is now a 106 pages thread, I did searched but didnt find anything concrete. Im having some issues with the sound, one that I already mentioned (crack sound on fring for example) but the other one is that sometimes returning from sleep will make me lose sound at all, and any attempt of "playing" any sound will result in a "SHHHHHHHHHHHHHHH" sound!
[G Tablet Android Development] anlog:
I might just be very lucky, but I feel like I'm the only one who HASN'T had any (major) problems with VEGAn. I am still running fine off the original beta 2 that I loaded from scratch. I think it's going on two weeks now? I loaded beta 3 on top of beta 2 (only wiping cache).

No major issues at all. Here are the things I've run into:

1.) Had to uninstall/reinstall Flash after installing beta 3 over beta 2.

2.) Slowdown issue on wakeup. Still haven't solved this one, but it's not a deal breaker since it takes 30-40 seconds for a shutdown and restart.

3.) On one occasion my volume was "stuck" on silent. A restart fixed it.

4.) Battery stuck at 100% for a very long time, then started to drop and device died at 40%. To fix I simply charged until green light + 30 minutes, then while plugged in went into CW and reset battery stats. Then I ran the tablet down to zero. After charging again to green light, the battery meter worked perfect (dropped to 98% after about 45-60 mins of light use).

That's it! As you can see, nothing major. I think that some of the issues people are having are related to the following:

1.) First, whenever you load a different ROM (TnT vs VEGAn, etc), your SAFEST bet is to completely wipe all caches and repartition the SD card. AT A MINIMUM, you should be wiping the data partition. Some apps store config data on the sd card, and it's possible that it could be conflicting with the apps running under a different "platform". If you are doing a minor update (beta 2 to beta 3, for example), you should be able to get away with just wiping cache + dalvik. That's what I did when beta 3 came out and I'm still working fine.

2.) DO NOT use apps like "quick boot". These apps do an instant reboot and don't cleanly unmount the file system. I'm certain that this causes many problems after repeated use. I always safely power down via the menu and things work great. Also, don't let your battery drain to zero too often, since this will also be an unclean unmount. I know TnT can die if the battery runs to zero. I've done it with VEGAn once and I was ok.

3.) Clear / wipe all data etc before uninstalling an app. I have a feeling that some apps can leave traces of info behind when they are uninstalled. As an example, when I manually updated Google maps to v4.7 (since the previous one was part of the ROM) I first wiped data with Titanium then uninstalled, then restarted, then installed the new one without any issues.

4.) BACK UP OFTEN. I make a full backup with Clockwork every other day, and sync that backup (along with a copy of my sdcard) to my computer. When things DO go wrong, it's nice to be able to go back to "yesterday", instead of "the beginning of time".

5.) Read EVERY page of the thread related to the ROM. I know we're getting into the "hundreds" of pages, but the reason we have "hundreds" of pages is because people keep asking the SAME questions, OVER AND OVER. I guarantee you, someone has already had the same problem as you, and it has most likely been addressed within the thread already. If not, then by all means be the first to post about it!

I hope this helps...
[G Tablet Android Development] pmcnano:
I agree with you, I am pretty sure im not the only one having the same problem, but its sometimes difficult to search for an specific problem. Also, we need to be a little more organized and make some comments and bug-logs so we dont bump into this. I mean, its not a big deal for me, I do a restart and im ready to go, also Im pretty aware this is a beta, so I was just asking to make sure that the problem has been adressed

The funny thing is that beta 3 is a 1000x more stable than any of the actual "releases" issued by Viewsonic for this device. I would release beta 4 as v1.0 if it were up to me.
[G Tablet Android Development] rcgabriel:
By the way, yesterday I finally had a slowdown on wakeup again with Vegan beta3, despite running Overclock Widget. This occurred several hours after I attempted to create a slowdown by slamming on the brightness control in Power Control Widget as was reported here yesterday, when I woke my G Tab back up.

I can confirm several things after studying this condition a bit:

1) Once the slowdown occurs, changing CPU settings via Overclock Widget doesn't do anything to change it. Setting the max back to 1,000,000 doesn't resolve the issue. So it's either truly stuck in a low clock speed mode and won't release from it, or something else is eating up CPU cycles, which was my thought, except that...

2) Killing all running apps doesn't change a thing.

3) I went through all the running services and stopped everything. That did nothing either.

4) I went through almost every possible app in the Manage Applications list, even the system stuff, and did a Force Stop on everything I could without completely crashing the system and that still had no impact on the slowdown condition.

5) After mercilessly killing everything in sight, I gave the system a few minutes to regain equilibrium. Still no change, animation was still choppy and laggy. I'm sure if I'd run Quadrant it would have been ass slow as others have reported in this state.

So I am fairly convinced that this has nothing to do with Flash (I hadn't used Flash at all yesterday afternoon). In fact, I was unable to identify any runaway app causing the issue and I am fairly convinced that there is no runaway app to blame here.

I also agree now that Overclock Widget clearly doesn't fix the problem.

I can only conclude that this is truly a kernel wakeup problem that for some reason seems to occur only intermittently on the Vegan ROM builds.
[G Tablet Android Development] rdscuba:
First, thanks a million for the instructional. Worked like a charm without any problems.

Second, now that VEGAn Beta3 is running (great), when I plug the tablet into my windows (7) computer it no longer mounts. I dont get the sd card to show up on My Computer so that I can browse and/or add software to it?
