[Q] Any white board app with minimal lag? - Android Q&A, Help & Troubleshooting

On a Nintendo DS you can write with the stylus and the 67 MHz CPU catches up with the strokes quickly but a Galaxy Tab 10.1 (1 GHz dual processor) lags horribly which makes handwriting totally impractical.
I have tried a few white board apps (skitch, whiteboard among others), but all of them suffer the same problem. Is there "whiteboard" or handwriting app that works without a noticeable lag? Or is this a problem inherent to android and its many abstraction layers?

I would reccomend taking a look at Autodesk Sketchbook. While this it's not originally made to be a whiteboard style app you could still use it as a whiteboard. I sometimes use it for handwriting and don't notice any lag at all.

Different Resolution?

Hey Guys,
I just have a small question:
Since the Motorola Defy has a slightly different resolution, can you still play and use apps like Angry Birds? I heard that some apps don't work on non-conformant resolutions...
Thanks in advance,
Wouternet
PS: How Bulky is it?
I have yet to find an app that doesn't work on the defy.
All the apps I've tried have worked fine, including Angry Birds (both the normal version and Seasons, I've tried 'em!)
It's actually quite slim but I've added a gel case onto mine which makes it slightly bulkier. I completely forgot its actual size - you can imagine my surprise when I took the cover off for cleaning
I am going to buy also the Otterbox Commuter, but maybe it will be a bit to much.
I'm going to put on the otterbox only when i know i'm going to be outside. Hunting, going to the beach etc
Just to be sure,
Anybody uses WhatsApp on the Defy??
i use whatsapp all the time...why?
the defy has paratically the same resolution as samsung galaxy s
(only 4 extra pixels on length)
i've never encountered a problem in an app due to resolution
WhatsApp and skype working flawlessly
There are not only 4 but 54 extra pixels i think.
Every games and apps are running great, there are no problems in resolution (no blank spaces)

defy has exactly the same resolution of the new xperia play, and of almost all the android moto too (droid, milestone etc etc...)
Believe it or not the Defy (along with the other phones that have the same resolution) actually has the correct widescreen ratio at 16:9. All the other ones (Desire HD for example) are 16:10, so if anything the other phone's resolutions would make their display not show correctly as long as programers do it right, and program for correct 16:9 resolution.

[Q] has anybody got Xperia Ray?

hi,
I quite like the new xperia ray and I was wondering some hands-on feedback (ie its responsiveness, speed etc).
in addition, a picture of Xperia Ray next to iPhone4 would be a treat. its not too big or too small as far as i gather.

It's simply lovely
Design is great, its light and nimble.
Screen is gorgeous, with 300dpi vs iphone's 330dpi, you can't see any difference.
3d games like guerilla bob run smoother on Ray.
compared to iphone it's lighter, less tall and much narrower.
Frankly iphone4 compared to ray shows it's age and bulkness, while Ray is shiny and modern piece of hardware.
I'm moving from Xperia X8, and comparison is pointless.
While I always wanted to "improve" X8 to make it usable, Ray is fine as it is, usable and fast. Battery life is phenomenal for Android devices, camera is great, sound is loud.
I'm sure if you get one, you will not regret.
Good luck!
I'm glad that you are raving about the xRay...
I'm getting mine tomorrow already paid my deposit for a white one...
You mentioned the camera is working great, just wonder if you've encountered any negative point coz I have read a few reviews which all have some negative things to say about the camera...thanks
got a full specs sheet?
My Xperience with Xperia
I second only some parts of the previous review.
1) The phone is beautiful, iPhone next to it looks old. Performance are very good, phone is fast. Software is ok, the Sony customization is not invasive at all.
2) Battery life is not really good in my experience. Up to now I did not manage even to do one full day. Screen is nice, but pretty scratch prone. I ordered a cover but after a week I have already some scratches (this drives me mad)
Hope it help.
Francesco
O...I thought the screen was scratch resistance...as it was mentioned in the specification section of a pretty well known phone web site...
I would have thought in these day and age...no one want a phone with screen that is prone to scratching...
I guess I should get a screen protector before start using mine...
I actually discovered that the screen comes already with a screen protector preinstalled

I'd like t know your experience with the camera, specifically:
1.- is there a dedicated camera button ??
2.- is the flash a REAL flash ?? (I mean the flash light up when you press the shutter or automatic flash mode vs "turn the light on or off" only)
Thank you
1. No
2. No. fixed light.

I think the auto-flash could be enbled by third party apps like vignette, has anybody tested ??

Vignette enables the flash 2 seconds before taking a picture, so no real auto flash.
I agree on the great battery life, the power save modus is incredible. 24 hours ago on 7% and now for 3 hours on 1%.
Got my Ray bricked already yesterday after an OTA update with unlocked bootloader, didn't know about that. Luckily I found this and this thread and now he's up and running again on 2.3.4 rooted.
I have 2 negative remarks though:
-I have the feeling that the 2.3.4 update made it a little bit less snappy.
- WIFI keeps flippin out on me. I think it's better/solved with 2.3.4, but with 2.3.3, it kept losing its connection without showing it in the notification bar. I had to disable and enable wifi again every time or even reboot. I even had to reboot my router because my PC's couldn't connect anymore. I googled and there are more people with this problem.
I find that the camera to have purple fringing problem, especially shooting indoors or night scene...white appeared to turn purplish...
The photo light is a tat annoying, I wonder if it can be changed to a flash...using software mod...
it will be great if someone can comment on the in call volume!

hey guys,
i´m also interested in the xperia ray.....sure the no camera flash is a little letdown but i´m worried more about the 300 mb storage. how do you handle that?? is it enough or way too small or maybe with app2sd?
would appreciate some user feedback
problem is i´m very picky when it comes to smartphone and i don´t wanna spend 400-500 euro for a so called high-end device that i don´t like 100%. the xperia ray seems like a good price/value phone

I Installed few games, few keyboards ime, overall just downloaded ~16 apps. Right now i have 227mb used and 193mb free.
Most apps can be moved to SD, but I think this phone is best for those who just use it to talk and the occasional smartphone activity. It's only 3.3 inch screen isn't suitable for a power-user.
BTW in-call volume is superb, answering myself from above; I used the service menu and tested the earphone side by side with my x10 and what can I say? 2011 SE have much higher quality parts compared to 2009/10.

[Q] Altering native resolution to alleviate GPU computation

Hi,
I noticed that the newest mobile devices sporting the latest GPUs have for the most screen matrices of size 1920x1080. I personally think that 960x540 is plenty (at least for a 5'' screen) and browsing glxbench I noticed that upgrading my device (running a mid range GPU with screen 960x540) to a newer device will not bring me the huge boost I was expecting as computation power will be wasted in filling up 4 times more pixels that I can barely see (or at least would not mind not seeing). From the bench it seems that the x4 pixel number increase imparts a 2.5x slowing down factor (1920x1080 offscreen vs 960x540 onscreen on my device). It seems very complex to change screen resolution under Android (at least up to 4.2), here are three questions:
- Why is it so complex?
- What is the easiest way? I will be already very happy with an option to run at binning 2 (1920x1080 --> 960x540) that could be activated on device startup.
- Will a native support will be supported in the next release(s)?
As a side question I noticed that some old games (especially Gameloft games) are not displayed right on my device (black borders + touch screen offset), changing resolution might cure it too... is that right?
Best, Sébastien

A bit of lag..

Is it just me or does this lag a little.?!
Don't get me wrong i love it, it's just i have a nexus 5 with the snapdragon 800 in it and it's perfectly smooth.
It's quick.. but not as good, particularly in web browsing zooming and scrolling. (sometimes you touch things when you dont mean too, sometimes it's slow to pinch zoom,maybe this is the touch screen issue not shaw.. )
Hopefully it's just software and sony will get it better. With this hardware it should be perfect!
Have you upgraded the firmware to the latest available ? Some people reported occasional lags that went away after upgrading.
yes I'm on 402..but my nexus 5 is smoother and it shouldn't be..anyway I'm still happy..
The touch screen does have a grounding issue, of which the severity seems to differ per device. Maybe that's what you are experiencing.
A 10.1 inch tablet which has the same specifications and is exactly as fast as a 5 inch smartphone will ALWAYS seem more laggy!
This is just because lags which are very small on the phone (bordering on un-perceivable) are magnified on the tablet and thus seem more severe!
But in reality it's just a matter of scale, an optical "illusion".
the nexus 5 has resolution 1080 x1920 and a slower cpu snapdragon 800...
i think maybe it is a touch screen issue, it's a bit random.
I'm sure sony will get it better..
Nexus has same resolution. Nexus is a pure android software with minimal background processes. Sony has customized their own ui with extra and not as optimized background processes. There is also the scale thing, where as u won't notice lag on small screen as much as big screen.
Ur welcome

Yes, right.
Coreo, you can use alternative launcher instead of the Sony one; you can root the device and disable/uninstall the Sony bloatware/unnecessary background processes.

The Z2 tablet actually has a marginally higher resolution of 1920x1200 pixels.
fair enough... but it still feels smoother and quicker.. yes I've rooted, deleted a few sony apps, replaced the keyboard with swift keyboard and installed nova launcher..
PS im not complaining, it's still fast and am very happy with it. im just comparing it against the snap dragon 800, as a fair or unfair comparison it may or may not be..
in someways its a good thing as sony have room to improve..

GAME TUNER(exclusive for samsung devices) for our devices

Is it possible to port this amazing game tuner app to our device?
How useful it is? according to my research...
Game Tuner is a truly useful piece of software? From Samsung? Color me surprised, too, but the company's new Game Tuner app is nothing short of incredibly handy for mobile gamers. As you may well know, playing visually-intensive games on your smartphone can demolish the battery fairly quickly. While most such games render at 1080p even on 2K displays like Samsung's, such resolutions can be big draws on both your remaining juice and your device's processor, causing throttling (and thus slowdowns) and excessive power drain. Samsung's new app lets you have a say in just how graphically hungry those games will be, allowing you to adjust maximum frame rate and resolution scaling.
For example, Hearthstone for Android on a Galaxy S6 edge+ renders at, near as I can tell, 1080p natively. With Samsung's Game Tuner app, you can turn that up to a full 1440p (aka 2K and probably not a great idea!), or all the way down to around 480p. The difference is very real. The frame rate can be adjusted from 15 to 60FPS.

I doubt it, samsung is pretty protective of their apps, even the simple 'note' app will crash on other devices

But it is possible I think -_-
The apk is available on apk Mirror maybe mod build prop like an s6e or s7 could permit to run it !
Nathing samsung use 3rd party app and give it it own name like it cleaner use clean master data saving use opera data saver etc don't bother it just find on play store
