I have been trying to develop a note taking app on my galaxy tab 10.1 and I kept having issues with handwriting. The accuracy was horrible. I could hardly make out what I wrote. I tried a couple things, but I'm fairly new to Android development. So, instead I ran to the local Best Buy to try out some other tablets. The Transformer and the Acer looked so much better when I tried writing in a paint app. Has anyone else noticed this? If so, can this be fixed on software or is this a hardware issue? I hope I can fix it. Note taking was a large reason I bought it. I may just return it and get the transformer.
Just a note, I used the same paint app to compare all three.
Which applications are you using ?
program
I was using the Free version of Kids Doodle. I've tried a couple of applications with touch screen writing and they all seem to have the same problem. I also tried a capacitive pen and that didn't seem to make a difference.
I dont have a stylus , but using the above program I dont see any issue with accuracy.
If you do a loooooong stroke like an endless circle it does trail behind slightly.
Perhaps a video for comparison would help.
I'll try to take a video when I get home...
I read through the post in your signature about the Acer v Tab comparison. I then read through the link you posted about the GPU acceleration. Could my issue be an issue with GPU acceleration. It seems to happen the most if I try to write at a "regular" pace. I saw someone mention input flooding. Are there just too many input points and it starts skipping points? I don't know why this would be different on the Asus and Acer. I did notice that the ASUS (and the Acer?) seem to have 3.1 slightly modified. It didn't seem to be vanilla Android. Could they have added some GPU acceleration?
If that is the case, maybe the update from Samsung with Touchwiz will help the situation.
My head is just spinning because I really wanted to use the Android tablet for some decent note taking. I'm thinking it is not going to happen, even if I put in the time to develop it. It's a little frustrating.
Are you saying that you don't see any lag on the gtab or the Acer? I wasn't sure which one you had.
Hello folks,
I have a question regarding the Nook tablet. I was making a delivery to a customer this morning and he has a Nook 16GBTablet. We got to talking and he indicated that he was going to sell it since his wife didn't use it. It looks like new physically and I am considering obtaining it for one of my grandsons, basically so I can get my Nook Color with CM7.2 on it back from him. Is the Nook Tablet a worthwhile barter or would something else be better? I bought a Samsung Tab2 7" tablet for a younger grandson a couple of weeks ago and he really likes it, But I don't think I can get a deal like I got for the Samsung. I only gave $169 for it new, still sealed in the box and I doubt I will find another deal like that as I'm pretty sure the fella sold it to me for less than he paid for it. I'm getting off track here, what I need to know is if the Nook Tablet is even a worthwhile Andriod tablet or would I be better off waiting a bit for the new, different brand tablets to come out?
Check swappa.com and see the prices for the tablets. Maybe you get to catch a good deal, I bought my Samsung captivate there and loving it. The nook is worth it in my opinion and the deal breaker is the sdcard slot . Nexus 7 temps me but no sdcard slot no way I buy it, anyways for what I do the nook tablet is enough. Tho I know kids love games and probably that is what they do in their tablets more than anything and the nook does a decent job with kids games, heavy games not that good.
Tablets with Tegra 2 chip is gamers glory and with dual/quad cores is a dream but your budget is not enough.
Good luck!

The nexus 7 is ( in my humble opinion ) the product of the year. The other major producers were surprised and knocked back on their butt. Now they have to answer back with something equal or better. Then there is the argument that it is 'not' just the product but the 'exosphere' along with the product. Lastly, the Nook is a fine performing tablet.
The Nook Tablet, was made to be a reader, but the xda community saw it to having more potential then BN wanted it to. The Nook Tablet has gone far from becoming a full-fledged reader into a usable, 7-inch Android tablet wonder. The Nook was at the bottom along with it's brother in technology, the Kindle Fire, as it was a reader, but it has pushed to the top, and now is one of the most popular tablets out there. I have a Nexus 7 myself, and it is amazing, but was at the top from when it was born. The Nook, and the great devs of this forum, had to work it up there, while BN did not help even once, except for the kernel. We even have our own nearly working kernel, thanks to Rebellos, Chris, and Kuzma. We have succeeded in reaching the latest Google experience, Jelly Bean AKA Android 4.1, and the devs hope to keep working and catching up with Google. As the problems slide off the radar, more devs have appeared. The Nook may not be a Nexus 7, but it sure damn does the job like it.
From what I've heard/read/seen I could make such list of tablets in this class, from best to slighty worse
1) Nexus7
2) Nook Tablet
3) Kindle Fire (note this has got better Android support than NookTab for now <points at Hashcode>)
4) Nook Color
There are for sure others, but I don't know others.
Also, if you want to use it as overpowered Android device someday - get 16GB version, it has got 1GB of RAM, while 8GB ver got 512MB of RAM and it might be not enough for some games, more browser tabs, etc.
Thanks for the opinions.
If I and the owner decide to work out a barter I may do the deal. Cash purchases are not many, but I do quite a bit of bartering and it is a 16GB Tablet. Have a 14 almost 15 year old grandson that could make good use of it I believe. Don't know how savvy he would be to rooting the Nook though he is really good with computers, he fixes all my messups.
When the reboot bug gets squashed expect lovely things coming along.
I get 1.9Mpixel/sec on this test on default clocks.
http://www.ziilabs.com/products/software/mandelmark.php
0.1Mpixel/sec more than Galaxy nexus o.o
Imagine 2x1.2ghz and gpu from 308mhz to 384mhz that can be easily be achieved without any problems as our platform 2.3ES defaults to 1.2ghz.
Is not implemented yet because of the 1st priority is to fix that reboot bug!
Also new drivers for graphic card are release from ti DDK1.9 i guess more speed will be possible also with them implemented
http://www.omapzoom.org/?p=device/t...it;h=ad17249821001789f159a5d5c542302e5f38cd2e
When our developers finish with this board you will have nothing to be jealous from Nexus7.
You would be able to play anything you throw at it
Edit: 2.2 Mpixels/sec on DDK1.9
As i said in the title, i've tried a lot of version of CM9, Cm10, liquidsmooth,etc .This problem remains. When i was in the Horizontal screen mode everything seems smooth and as soon as i switch my screen to vertical, it becomes sooo laggy. It's very obvious when you try to open the drawer of the app, try to compare the speed with the Horizontal screen's . I hope this is not only my problem.
It's not only your problem. I and others have brought this up on the occasion in the past, but not enough people seem to give a crap. I know some of the tegra 2 tablets have this issue, but no one seems to be able to provide an answer in the case of the TP.

This is a common problem with Android tablets since Honeycomb. It only happens in the tablet UI. The Nexus 7 I had, which runs a Phablet hybrid version of Jelly Bean which is more like the phone version of the OS worked fine.
Here is a video demonstrating the problem.
http://www.youtube.com/watch?v=9jbm8QAS3DI
the gist of the video is that when you are in any orientation other than the regular landscape, the frames per second displayed by the OS goes down.
I am an Android fanboy to my core but I just got my touchpad and I have to admit, I like webOS better. It is too bad about the whole "dying OS with almost no apps" thing. If HP had any vision, they would have stuck with it.

thx for you explanation, but is there any chance that touchpad can get the same UI as Nexus 7's?? BTW, Webos is really a good os but has little number of apps
Hello everybody,
Since a few weeks, i had 'only' 1.6gb of internal storage free, my nexus 10 was slower then before, it took around 5 seconds before the screen turned on and the launcher was regularly stuttering. Now, i have cleared the cache, site data and cookies ( chrome app > settings > advanced > privacy > clear browsing data) that was about 500mb. After that all the problems were gone. Has anyone else experienced this ? Let me know if freeing up space fixed the problem.
Greetings,
Inse

I find that very strange, considering that the Nexus 10 has some of the highest-scoring I/O benchmarks around. This kind of issue is obviously I/O related (at least, it seems so). I don't get mine until Monday so I'm not entirely sure, but that shouldn't be happening. I've heard reports of this on the Nexus 7, obviously due to the sub-standard I/O, but not on the Nexus 10.
Could you try doing some I/O benchmarks with AnTuTu or similar app in your N10's current state, and then again with lower storage? That might help diagnose the issue.
I heard of this being an issue on the Nexus 7 on 4.2, but it was fixed I think on 4.2.1 or 4.2.2, haven't heard anything on the N10 though.
Thanks for the replies, do you guys think i should send my nexus 10 back ? I have several other issues as well:
-overheating
-very unstable (freezes a few times a day)
-strange 'sssssrrrt' sound from the right side of the rear camera, i think that it is the processor. (That place becomes hot while playing games. When i say hot i mean very hot, my finger almost hurts when i touch that place)

Before sending it back, as written in the previous post, are you using Android v4.2.2? That android version dealt with a number of issues that plagued the N10. If you are on that release and still have the described issues then send it back. My own N10 is on v4.2.2 and does not have any of those problems.
With the symptoms you mention I would definitely exchange it.
Ok, thanks guys. I have android 4.2.2. But, will google reinstall all my apps with data on my new n10 ?

A lot of complaints of lag and freezing seem to be due to not enough random access memory. Shame that a nicely built tablet with great specs (Qi charging, 64-bit processor, vanilla Android) would be useless to many because of this issue.
I got one for $133 new from the Dell outlet with a sweet case for $15 both in red and gave it to Mom for Christmas, knowing that for her use it would be acceptable.
Here's what I found and how I've gotten the tablet to work great and have none of the issues.
1. Stick with the stock KK launcher. Forget Google Now or Nova as these use up too much memory.
2. The stock browser seems to work the best. Dolphin, Boat and others have been reported to be problem free too. Chrome is a no go.
3. Under Developer options shut off the animations as well as limit the background processes.
4. Disable anything you'll never use, and only install the apps needed.
5. Under "Google" account and "search" make sure Google Now is off.
These things may be self evident to some, but you will notice a night and day difference in the way this particular tablet operates if you stick to those things. At $130 it can't be beat.
Apologies for responding to my own post, just wanted to update, apparently Dell pushed out a OTA update recently that updated the kernel and the thing is much improved if not downright zippy now. Still would stick with my suggestions as I've noticed while Chrome may be somewhat usable it will still freeze.
Thanks for the tips. Despite the horrible reviews, I just ordered one from Amazon Warehouse for $75 Very Good condition. At that price, it is worth taking the plunge.
Use the stock browser keep off any RAM hogging apps and you'll like it. For $168 total I got a red one , the official red case and the dell wireless charger. Can't beat that price. It particularly excels as a movie watching device for travel. Good size and format, great battery life and storage with an optional SD card, and a 1080p screen. Seems to handle video playback really well too, stutter free.

We're taking it on the plane for movies in 3 weeks, so that'll be perfect. Have you tried rooting and Greenify app? That could further help keep the background processes in check. I have a 1st gen; wife will get the 2nd gen, but if I like it enough, I might get another one for myself.
No I haven't mainly because of the amount of bricks being reported. Too much headache and since its my mothers there's no point. Lol. You'll love it for watching movies I swear they look better than on my Nexus 9. Maybe that Intel video enhancer or whatever its got really works well. The speakers are loud and sound great too.

So I've had the tablet for a week now. The amount of bloatware pre-installed was insane. I was surprised since the 1st gen 3830 came with almost zero. After disabling all bloatware and all google apps, disabling animations, disable sync, disable backup & restore, it's running fairly well. Chrome browser is definitely not happening. Stock browser is good, but opening multiple tabs is still guaranteed to make the tablet lag.
All in all, this is a great tablet for someone who only does one thing at a time (No multiple browser tabs and switching back and forth between apps). 1920 x 1200 Screen is awesome, build quality fantastic, thin and fairly light, 802.11ac wireless, wireless charging, almost pure Android, and good enough battery life. This thing is perfect for my wife and was a steal at $75 from Amazon Warehouse. Got a $7 case from eBay and my wife is loving it. It's a big upgrade from her Nexus 7 2012.
That being said, I will not be picking another one up for myself unless we get a magic update that makes it as fast as my 3830. I like to multitask, so that's priority for me.
P.S. After all updates, I ran Antutu and the tab scored 33,000 vs 24,000 for my 3830. Sadly, real world experience doesn't reflect this.

Lol, my mother went from my hand me down N7(2012) to this and so far, with the way I've set it up, she likes it for her style of use. It really is a shame as if the darn thing had 3 (gasp!) gigs of Ram it would be a killer little tablet, the fact that you can pick them up so cheap is another huge plus.
Hi! CJ, I have a Dell Venue 8 3840, and for some reason I'm unaware of, it's WIFI, & BLUETOOTH, have completely being "lost", I.E. the icons, the Settings options etc.... Have " disappeared ".
I would be most grateful for your advice on it's recovery.
Thanks & regards,
Mahil.
Hmmm, never heard of that happening before. I could ask you a bunch of questions to see what may have caused it but instead my advice would be do a reset. Under settings/back up & reset/ factory reset. Back up whatever files you don't want to lose, the cloud works great for that, and then reset. See if that brings it back.
Venue 8 touch screen freezing issue
I had bought my tablet online. It was working well initially. Then suddenly from one day the screen started to freeze once it was not in use for minimum 7-8 seconds although the tab was not hanging, just the tablet touch screen was not responding to touch.
my dell venue 8 3840 has kitkat 4.4.4. WiFi Bluetooth is not working at all. when i press on in the WiFi option, it goes to on but color doesn't change, i mean it keeps grey and it doesn't scan any WiFi signals. nothing happens on the screen. its like frozen. add device and reset options on WiFi menu are also freeze. when i come out of WiFi menu, it automatically turns off. i have already reset my tab 2 3 times to check if the issue resolves but the prob persists. advanced options are working. when i go there, it says mac address and IP address unavailable. and these options are also freeze. am not getting a clue of what has happened and how to get it fixed. plz help.
Dell Venue 8 8340 slow fix
Hey guys,
I have found a solution for the extremely slow performance of the Dell Venue 8 8340. You must disable wi-fi optimization in settings --> wifi --> advanced. After disabling this feature, the tablet runs fairly smooth with no crashing or delays. This may be a temporary fix; however, it does seem to affect the tablets performance. Also, I did not have the time to check if this fix has been posted, sorry for the repeat if it has. Please update on whether or not this tweak works for others.
Setting 'Developer Options' -> 'Background Processes' to 'At most 2 Processes' seems to help with performance. Reboots and updates sometimes reset this to the default though.
