HTC EVO 4G :: 6.1 Performance Speed For Page Scrolling
Oct 29, 2010
What kind of performance are you seeing with 6.1? I'm pretty unhappy with the speed it takes for the app slider, page scrolling and all that. I didn't run a quadrant score, I'm not really bothered about numbers. I switched to LP, that didn't help. Also, snap kernels are not playing nice with 6.1 yet (anyhow, the snap kernel features are reportedly built in), so nothing there. I'm back to myn2.2 with overclocking and it's smooth as silk.

I have a listview showing contacts.
When I'm scrolling the list the scroll works pretty smooth however when/if I'm trying to continue the scroll in the middle of the last scrolling the scroll just stops and sometimes the item I clicked on is selected (I have registered an OnClickListener to the item view).
I would like to get smooth scrolling just as in the device native contact list.
My implementation builds each contact a view containing: 1. Big picture for the contact image. 2. Small picture for the type of the contact. 3. TextView with the Contact name 4. TextView with some extra text about that contact.
My current layout for every item looks like:
CODE:........................
I've tried changing the LinearLayouts to relative ones but saw no improvement in performance.
I've created my own "Selector" in code (to eliminate the time it takes to load the resource) so that odd rows will have different background color. The code looks like:
CODE:........

I have my Vibrant rooted, deleted bloatware using titanium, and running Ryanza'sOCLF...any other easy ways for a noob like myself to increase speed/performance or make the phone better overall.
Should I get setcpu? If so is there any danger of overclocking/how should i set it up?

Currently, attempting to scroll when the text view has large amount of text makes the app completely unresponsive. It doesn't ANR, but it doesn't respond either. I've tried occasionally removing some text from the text view and removing some spans also, but it doesn't seem to help much. Any idea how to improve scrolling? It takes ages to scroll up or down. I also tried throttling touch events but it hasn't helped either.

How does higher MicroSD HC speed of class 4 and 6 helps with Xperia X10 performance?
Any changes based on your experience?
Considering Xperia X10 processor Input and Output MB/s VS. Class 2 (2MB/s), Class 4 (4MB/s), Class (6MB/s)

I am about to develop a web application for smart phones. This app uses some JavaScript code. While testing it on Android devices (Hero, Desire) I noticed that all JavaScript timers immediately stop when the page is moved or zoomed. They never continue. Let's say you have a site which displays web camera images with 5 fps. As soon as you move this page (I mean scroll with finger) the web camera image will never be loaded again. So you can't center or zoom the image at all without stopping the stream. This behaviour is 100% reproducible on all Android devices I tested (1.5, 2.1). It does not appear on an iPhone which continues execution after moving stopped fine.

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

I have the tronsmart CX-919 mini pc running 4.2 and there is an issue with the browser reverting back to the home page or the previous page. When I try to display a webpage on our intranet it reverts back to the homepage or previous page after about 3 hours. I need it to display constantly. I read somewhere that it was a Download Manager issue and disabling it would work but I can't find where to disable it. Also it was stated that Flash was an issue but i tried uninstalling it and it just reinstalled itself and the problem kept occurring. I just want to display a page in a browser and for it to stay on the screen (full screen) until I manually navigate away from it. I plan to leave it on for weeks at a time.

how do you paste copied text (ie a URL) from a web page into a new window to open that page?
Also can you restrict internet connection to 3g or 2 g only?

Why is it every time I go to the internet, the last page viewed shows? I have my home page set to "Google." Shouldn't Google be the page that shows up? Also, it seems to save the history, even after I delete history, cookies, caches. Why? I was told to try and keep this, as well as deleted email, empty or the phone may become slow.

I've been trying all the new kernels out there and still my best performance is coming on Snap 7.1 running the latest cm6 nightly. Quadrant over 2200 and Linpack over 39 (see pictures): I don't think Snap 7.1 gets into all the heavy voltage regulation stuff. For me, I'm not willing to sacrifice performance for an extra hour of battery (I just bought a bigger battery).

Am I the only one, or is there a problem with the EVO and 4G speeds? In the Houston Area, I get anywhere from around 600 kb/s to 2600 kb/s speed. In most all cases, the 3G speed is faster than the 4G. At home, I average around 700 kb/s with 2-4 bars signal strength showing. Tech support is working on this with me and trying to determine if it's a phone problem, or tower problems. I had a chance today to journey around the area within about a 10 mile distance, thus insuring it changed towers. Service stinks on 4g, to say the least. Clearwire tells Sprint Tech Support that the tower for my home has low use, and good throughput. If the tower is good, and the software on the tower, then there may be a HTC EVO problem of some kind as this is the same on 3 different HTC EVO's purchased within 2 days of each other.

I deleted all battery monitoring apps and stopped looking at the battery usage info 50 times a day. I did this over one week ago, and couldn't be happier. No more looking at that god awful percentage meter, no more watching in dismay as it drops, and drops, and drops. My battery performance has never been better now that I quite looking at it all day and my sanity has slowly begun to return.

This last weekend during the pre-release (7/30/2010) we learned a LOT about Froyo on the EVO by exhaustively searching down every problem. Here's the simple story for any number of bugs, erratic behavior and incessant up time. This is NOT to going to solve all problems for 100% of you - but - I'm very confident that it will for most of you, as in - OVER 95%.
It will NOT fix these classes or types of defects:Pandora / Slacker users.. Please star this bug.. GMail non-primary account not syncing/notifying in real timeThis one _might_ be solved with this workaround Google speaks up on GMail with Froyo. My personal approach to mail
Any apps that are known to have Froyo issues. This is usually the hard step, because it requires you to check the comments against your installed apps - that's not tough per se, but it can be time consuming if you have a lot of apps. Go to Market, your downloads, inspect each apps comments if you continue to have doubts and need to be sure. At least the new Market app gives a Comments tab, making this job easier. The worst case is starting over, installing apps one by one until the culprit is found. MANY users found Facebook 1.3 seems to have been the culprit on their machines - another user found it was a wallpaper app.
There is one pathological class that is making no sense that we're trying to track down; at least two people are finding a runaway CPU, takes-forever-charging, and no battery staying power EVEN AFTER FOLLOWING THIS METHOD - and in one case at least only using stock apps! This may or may not be limited only to PC-USB charging however.We're working together to solve this one.
My personal latest guess is on the SD card - but - I know this was seen and solved for 2.1 but I cannot find that thread for love nor money. Was it a reformat to FAT32 from a PC?
If you know the answer, please post it in this thread!
Found this! I'm not expert as to whether to format on phone or using PC - there's some controversy on this, but using the phone to format the SD card DOES make sense.
Possible Swype fixes - or anything specific to some app's idiosyncrasies
A corrupted 2.2 update file.This is insanely rare, but not unheard of, and has been reported to have happened at XDA.
This is insanely rare.
Here's the deal - the updates do not have a lot of defects - aside from the above list - it has essentially one big one.The cache / data areas are tangled up.
As you run things over time, your cache - the area where lots of things get worked from - has gotten all tangled up. Just like your web browser has a cache, Android has data and cache areas - once tangled up, all sorts of symptoms appear.
The solution is simple:
Backup
Factory reset / wipe data
Restore
1. Backup
Backup is important with every phone.First and foremost, ensure the Google servers are up to date with your contact and calendar data. Menu -> Settings -> Accounts & sync -> Sync all. If you are using any third party apps for this sort of thing, or corporate servers or Exchange accounts - be sure that your contacts and other information is appropriately synced.Verify that your contacts are on the Google server. Yes - do that!
If your chosen backup method will support it - next go to Menu -> Settings -> Personalize -> Scenes -> Menu and this will save your 7-desktop layout.
If you've got 5 bucks and you're not rooted, get MyBackup Pro, it should backup everything you care about. Another good alternative is Sprite Backup plus ASTRO used at the same time.
If you're rooted, use Titanium Backup - backup your user apps, desktop, Mail, and everything marked with "Titanium."
If you're not comfortable with the above, you can backup your apps for free using ASTRO File Manager, free from the Market. Once you have it, go to Menu-> Tools.Here's a thread on ASTRO, wish I'd found it earlier!I'm leaving AppBrain.
If you've never done this before - NOW at this point would be a good time to back up your SD card to your PC. Simple select all, then drag and drop into a clean folder onto your PC via USB should do the trick. This isn't required - but you can never have too much backup protection.
2. Factory reset
Once you have your backup, goto Menu-> Settings-> SD & phone storage -> Factory reset.You WILL lose your installed apps.You WILL lose your local logins and accounts unless you use a better backup than free - but you're likely to not lose much. (If you're synced to the google servers - and you should be - you'll still have your contacts and calendar entries.)
You will NOT lose your SD card contents. (But be safe and back it up to a PC as noted above.)You will NOT lose your 2.2 update.Do the factory reset.
3. Restore CORRECT Behavior *and then* Your Stuff
When finished - download the free Network app from the Market. (Network by Philipp Mangelow)Start it, and scroll down until you see "CDMA auto (PRL)" - change it to "GSM auto (PRL)" - exit Network; re-start Network then change back to "CDMA auto (PRL)" - and finally, go to Menu-> Settings-> System updates-> Update PRL
This sounds like majick snake oil but it's not - it's an idiosyncrasy of the phone's hardware and firmwareDepending upon your particular apps and backup tool, you may be required to add this step, so now is a good time (if you're uncomfortable with this, you can do it if and when required):
Menu -> Settings -> Applications -> Unknown sources (check on to allow non-Market apps)
Now, go to the Market and download again the tool you used for your backup.
NOW restore your backups by reversing your chosen tool.
DO NOT re-install full Flash 10 for 2.1 if you had that before.
Consider NOT re-installing LED Light, the included Flashlight is really better.
DO NOT re-install any task killers or cleaners.
At least one user has found that if this doesn't work and issues remain, then power up your phone while holding down the volume-down key. This gives a menu that includes an option to Wipe/Clear all data from the phone. Use that by navigating with the volume buttons and selecting it with the power button. Use the menu to reboot when done.
4. Stock Browser Note
When you're done, you may still notice browser slowdowns from before.
This is easily fixed.Menu-> ... More -> Settings -> Clear cache
Settings -> Enable plugins :: change from always on to just on-demand. This will prevent your browser from caching all of the Flash content it can find. This will also require you to tap on a green icon in flash videos and that sort of thing.
This is a user-choice for how you want YOUR browser to behave.
5. Et cetera, et cetera
It seems that when you do this, Talk may be set back to auto-login on startup. If you're not a big Talk believer, you might want to shut that off to conserve battery life. You'll find it in your app drawer.
Likewise ou can also turn off Background data under Settings -> Accounts & sync. The cool thing now is there is a widget, available under Shortcut -> Settings for your desktop that'll take you right to that page whenever you want, conveniently, like when you want to go to the Market, for example.
Talk has some controversy as to whether it can impede instant notifications for GMail - and many people are uncomfortable with background data for any number of reasons - I'm just no longer sure, so this is more "customization how-to" rather than strict advice or anything.
By the way - there's a Sync All widget now, under Widgets, for your desktop that does just what the name says. Best of all - you can have background data and auto-sync off, use that new Sync All widget from time to time - and they stay off.
I'd also like to note this specific advice if your Sense launcher is force closing and not letting you get anywhere -
FIX: "The Application HTC Sense (process com.htc.launcher) has stopped unexpectedly"
Note well that the article ends suggesting you may have to follow this post's procedure. Yes, do.
There's also a note at XDA warning to turn off your LED notifications. That's under Settings -> Display. The new default is for all of them to be on - and this is said to cause some process to run, draining some battery life.
Settings -> Wireless & networks -> Mobile networks - ensure that "Enable always-on mobile data" is not enabled (not checked).
Settings -> Wireless & networks -> Mobile networks -> Roaming -> Sprint only
And finally - Sprint Zone - turn off its auto-login and any notifications it wants to send, unless you really have some use for it.
6. Summary
I've started this thread to help out with the many threads for people with problems.
Please keep this thread clean, and only respond if you're having trouble with the procedure.
From the smallest bug to the largest - this is best advice you're likely to ever get with your EVO.
Finally - and this is VERY important:
If you're using a task killer or cleaner, stop for the moment, and uninstall it.
The task-killing protocols for Froyo are NOT the same as they were for 2.1.
And Froyo is so much better at memory management - AFTER you've done a factory reset and cleaned out your cache / data tangles - you're not going to believe.
Try your new Froyo for a few days like this and then and only then if you're still convinced that you need a task killer, go for it. But not because of the number of tasks running - wait and see if you don't already have better performance than before.
Hope this helps, thanks in advance for your help in keeping this thread clean.
PS - This advice is the result of the efforts of too many people to name individually who pulled together in this forum since last Friday's pre-release of Froyo. They know who they are, and without their efforts this knowledge would not have been possible. I thank them, one and all, on my behalf and yours.
PPS - This advice is for the HTC EVO 4G on Sprint and may not apply to all devices.
Definitely do NOT follow this procedure if you're using a Motorola Droid X and are on Verizon.

I've been experiencing slow scrolling and overall sluggish performance like others. I got rid of the big sense clock/weather widget because it was covering my new wallpaper. Now things are moving MUCH smoother. I even make less mistakes while using the on-screen keyboard. I also switched to a still background and things got faster. Anyone else have a similar experience?
The only large widgets I'm using is favorites and bookmarks.

So if you have ever used Cupcake and upgraded to Hero ROMs, you will obviously notice differences in performance. While you most probably won't be able to make the build go as fast as cupcake, this guide will help you squeeze all the juice you can out of the build, mostly by deleting useless resource-hogging apps. Please note I am not responsible for any damages to your device. Now lets remove some pretty useless apps. Obviously if you use any of these, do not remove them.
1) HTC Sync. If you don't use it, delete it. It is really a resource hog. Please not that before starting any of these command. Please not that you only need to type in adb remount once before you type in all these codes. Note: Please note that the * after PCSII* is in fact supposed to be there, and is not a typo!

The Engadget review said it was pretty much unusable when sunny outside. Many of the reviews mention the poor performance of screen outside. I really do not have issue with this if this is only referring to direct sunlight. I can always turn so that the screen is in shadow. I have looked for videos of phone operation outside but I have not found any. I need to be able to use phone outside and in car with no issues. Could people that have Incredible comment on how it performs outdoors when it is sunny?

We acquired a Samsung Moment today, and find that it's 3D performance is very poor compared to the HTC and Motorola devices. I've tried all the tricks I know (color depths, rendering options), but can't get much out of it. Rotating a single textured quad is jerky. I understand that the Galaxy was missing a software component, and that once a surrogate was added, the 3D performance was acceptable. Does anybody have the real low-down on this issue? Specifically: * Do others also find the Moment to be a poor 3D performer? * Is there any word about Samsung fixing this? * Am I missing something obvious?

I've been trying VBOs (3D) and I've seen no improvement at all on my Motorola Dext over not using VBOs.I've tried all kinds of configurations, interleaved arrays, by t buffers instead of float buffers, both direct and indirect. My question is, has anybody got any measured improvement in frames per second by using VBOs instead of exactly the same content without VBOs? If and only if so, what were your fps results? And can you therefore show me the "proper" way of doing VBOs instead of not? Has anybody else got exactly the same fps with and without VBOs?

My experience is that loading websites in a WebView is much slower than performing the same actions in the Android Web Browser. I can see that all files have been loaded in my Apache log, it will take a few seconds until the page is displayed in the WebView control, however. Opening the same page in the native Web browser will result in an immediate display. It seems that rendering is somehow crippled.Which browser settings do we have to apply in order to achieve the same performance as loading the page in the native web browser?

Just got my N1 upgraded to unlimited web use through 3. Had to set up the APN. Did that in work and looked forward to `consuming` on the train journey home.
How cheesed off was I when I got diddly squat in the way of speed and function from the network?!
Endomondo - did not work, no maps
Google maps - never registered my position
Web - realllly slow to load anything
GPS tester - only found one or 2 satellites nd never made proper contact
Anyone else got an N1 with Three? Performace pants? Any other networks just as bad?
