Home Screen Redraws - Galaxy Tab Q&A, Help & Troubleshooting

Hi all,
I understand this issue has come up elsewhere before but I wanted to see if anyone here had any good strategies for dealing with it.
On my rooted GT-P1000 running Overcome3-Jupiter and Overcome Kernel, when I return to the home screen after a while in other apps, it has to redraw all the shortcuts and widgets, a time- and CPU-intensive process. I have noticed this on the stock launcher, on LauncherPro and on my current launcher, Zeam Launcher. I have tried using the V6 Supercharger script and I have tried using the edit to local.prop and neither solves the problem (I swear V6 made it worse). I still have extremely regular redraws when returning to my home screen, which is becoming irritating.
Does anyone have any other ideas/strategies as to what might be either the cause or a solution for this annoyance?
Thanks everyone!

The cause is when the launcher gets swapped out of memory to free up memory for other processes.
The solution is locking your launcher in memory. LauncherPro has an experimental setting that supposedly does this, but I have seen a lot of people say it doesn't work. However, on LauncherPro's forum, there is a more involved method for root users as I recall that people report does work.

Wow, this must be the first ever redraw thread created where the OP is aware of the V6 SuperCharger...
Congratulations... but if you can't get SC to work, you're SOL.

[Q] Notification Bar ~ Refuses to Pull Down/Open

Guys,
I have recently started to have an issue with pulling the Notification Bar down.
Occasionally (and for no apparent reason) when I attempt to pull down the window it opens just a fraction with only the bottom grey part of the window showing.
No matter what I do I can not get it to open fully. The only course of action is to reboot the phone which then clears the problem.
Any ideas what is going on here?
I have also noticed this behaviour and wondered about it

Hello,
I get that as well from time to time. Only way to display the bar is to go in the main screen, press the menu button and sellect 'Notifications'.
Hope it will be fixed soon as it is really anoying bug.

Thanks for the tip... Forgot all about the Menu/Notification. I'll try it the next time it happens.
I have the same problem. I cannot, or only partially, pull down the notification bar. Menu -> notifications still works. It started 2 dags ago after i used Samsung's own RAM manager to clear level1 and level2 memory. First time I ever used this feature, and will also be the last. A reboot does not solve my issues.
Is there a way to clear notification bar cache, or the notification bar settings? This information must be stored somewhere, similar to that of other apps?
/edit
Yes, I also use launcher Pro.
On another note, after removing the battery when the phone was still on (so no proper shutdown) the problem disappeared.
hi,
could it be you guys are using launcher or launcher pro? I had the very same behaviour and installed adw launcher, wanted to compare those two anyway ... since I had installed adw launcher and used it the problem vanished ... so I assume its a problem of launcher pro ...

Ohh, give it time... If the little blighter has already been seen to happen there's a fair chance it will pop back up again right bang when you don't expect it.
I went well over a week without it myself then all of a sudden up it popped.

You mean you had the phone connected to a charger, otherwise it would simply reboot.
Only got to experience this once after 2.2 update. No apparent in 2.1. Here are my other observations. It does not pull down on portrait, but does on landscape. I am also using Launcher Pro, not sure if same thing happens if I am on TwLauncher. I installed z4mod lag fix thinking this has something to do with Samsung's programming. Haven't encountered it since. I would die if I would. LOL.
I just noticed that even after the z4mod lag fix, my Galaxy S is still not top notch in snappiness--lags from time to time, but way worst before the lag fix, phone was bordering useless due to how many times it froze. Kinda of irritating seeing that my X10, a much cheaper and technologically lesser phone, does not have this problem. I hope Samsung gets their act together as this phone has so much potential.
I have the same issue but I am on stock froyo, no lag fix or root. looks like a bug

I had the same problem with my galaxy s untill i uninstalled the Juicedefender app. Now it works great with no problem whatsoever (i use laucher pro).
I encounter the same issue once in a while, on stock froyo official update. Using launcher pro and zeam. Read somewhere that some apps that appear on the notification bar may cause the issue, so I've uninstalled them. Mines sticks whether in portrait or landscape format, and I believe after a notification appears. Shutting off and turning on doesn't always help but the problem usually goes away after a few days.

Don't forget hitting Menu and selecting Notifications will bring the Notification window down.

Modifying the stock UI

Hey guys,
Currently running CM7 RC4 on my emmc. I was thinking about going back to the stock firmware, because I'd like to use the B&N functionality in store.
I have seen a lot of nice themes on rooted stock. I was wondering if anyone could point me to how people go about adding a custom launcher and homescreen? Is it as simple as installing ADW or Launcher Pro?
I've noticed that a lot of the time they are able to keep the stock pull up menu on the bottom of the screen, with a appdrawer launcher immediately above it.
Thanks for the input!

I've read a number of posts indicating no success with in store reading with a rooted nook, stock or otherwise. It appears it may only work with a non-rooted stock OS nook.

Not true. There is a thread here that shows how to do it with BN 1.1.0 and rooted with auto-nooter 3.0
Hmm...browsing the forum it appears that a lot of rooted users do indeed still have access to in store features. Therefore, my original question is still pertinent for me. But thank you for the warning, I appreciate it!

I can do everything in the store with my autonooted 3.0 Nook Color, including 1 hour in-store browsing of titles.
I've got all sorts of stuff installed on my NC, too.

Pretty much. What I did is basically what's outlinked on the nookdevs site:
1) Installed custom launcher of my choice (ADW originally but switched to LP because it's so much smoother/quicker for me.)
2) Used home switcher to set soft keys as the default launcher
3) In Soft keys set it so your custom launcher is the default launcher. (I also have SK setup so one click gives me "home" and two gives me the soft keys.)
The stock pull up menu is still there and works for accessing the stock B&N stuff, but for the most part it looks and works like a normal android device.
As for the in-store stuff. It sounds like the problem is with B&N still having some issues with in-store setup to support the NC at some stores as people have also been reporting the same problems with stock non-rooted NC's.
I use Zeam, without softkeys, as the stock notification bar has all of that functionality.
Zeam is a tiny bit buggy on the NC though. Anyone know how to set a different launcher as default?
Install another home launcher and home switcher. Hit the N button and it should ask which launcher to start with. Make sure you check the box so it will set that as the default launcher and launch the one you want to be your default.

Getting back to Zeam launcher

Hey everyone, hope to get some help here. I put 1.2 ont he wifes Nook the other day, then last night decided to go ahead and root it. However, using Home Switcher, I accidentally set Home a default instead of Zeam.
I can't seem to find a simple process to clear that default setting from the Nook Home launcher. Can anyone help?

Run Home Switcher again.
Thanks, but I can't seem to do that from the stock home screen, it isn't in the apps list.
If you can get back into the market, install another launcher, or uninstall then reinstall zeam. That should reset the first home button press to select launcher.
If he is on 1.2 non bn apps.do not show up in their launcher.
If you happen to have.softkeys running just get into.the setting.of softkeys and change home buttom.option

yeah, that was what I was thinking. I tried to download softkeys last night from here, but 1.2 won't recognize the file type. Guess I will try again later.
If you can get into the Applications Settings screen, you can clear defaults on the home launcher and that should do it.
Same problem...
I'm having the same problem. I mistakenly set my N button to Home and now it is as if my device is no longer rooted. With the 1.2 root, the Apps button only shows B&N apps. I hoping someone has a solution, so I don't have to start all over...

If you rooted, then you should have Nook Color tools in your apps. Go to Nook Color Tools>Settings>Manage Applications and find Zeam. Then clear the defaults and back out of the application. You should be able to make a choice between "Home" and "Zeam" as your launcher when you press the Nook button.

With the MN root for 1.2, the B&N Apps button/screen only show the B&N apps, tho... I'm hoping once 1.2 rooting is further along we'll see all of our Apps, but not at this point. I'm still hoping there is some way to do this, so I don't have to start over.
I ran into this same thing. To fix it, going through your web browser and install an APK for something launcher related. This will make android bring up the "Default Launcher" prompt the next time you press the 'N' button.
Try something like this, get back into Zeam, and uninstall it:
http://forum.xda-developers.com/showthread.php?t=827288
Edit: If you can browse to the Zeam, Soft Keys or Home Switcher APKs, I suppose you could reinstall and that would also bring up the prompt.

I wasn't sure if I was going to get any ideas, so decided to go ahead and start over, so I'm back to stock now and updating to 1.2, then will be MN again. I did take a quick look at the link you provided, tho, and must not have read through it closely enough, because it didn't jump out at me what I would have done. It was a post about phones, but I assume that was okay.
When you say to go through my Web browser and install an APK. How would I have done that? Using the browser on the NC, can you install applications from market.android.com? I didn't think you could...
I'm back MN rooted now...get to reinstall all my apps and fun stuff! Boo! I won't do THAT again!
On a semi unrelated note, has anyone else noticed significant lag when panning through the app drawer using zeam? Using phiremod cm7 I switched to adw (stock) launcher and it seems so much smoother even though I'm not clocking it as fast (1.1 to 800 MHz) which I found extremely odd

For some reason ZEAM's app drawer does lag on all versions of the BN software thats rooted. It has been seen by many users here. If you try launcher pro much better app drawer and totally smooth even more than the stock app drawer that comes with android operating system. Although I beleive you cannot do specific things using launcher pro that you can do with zeam!
I'm having the same problem. I mistakenly set my N button to Home and now it is as if my device is no longer rooted. With the 1.2 root, the Apps button only shows B&N apps. I hoping someone has a solution, so I don't have to start all over...
How did you get your N button to set as physical home? Are you using Soft-keys? In 1.2 so far I have not managed to engage the N button at all to go HOME. Ended up locking the Soft-key HOME icon in the Taskbar to get out of BN screen.
Easy fix, from home launcher: search, then just search for Zeam or what ever app you have installed. With search history on it could even be considered a crude app tray.
do a search, apps should come up in the search list and you can access the launcher from there.
Haven't experienced Zeam lag...

[Q] Problem with Go Launcher ex

I love this launcher very much but its giving me a headeg. When I used 2 times it deleted all setup and got back on default and when that hapend it also deleted some progres on app and games.
From then I used Nemus launcher and didnt have this sort of problem anymore.
Dose someone where the problem might be?

EDIT- strange but I cant find zeam launcher on market
Thats your choice,but zeam is faster and stabile. Find apk file on internet,but it should be on the market

Hello!
I've been using GO Launcher EX with custom ROMs (Floyo 0.20, 0.25, 0.30 and FroyoBread now) and it never did anything like that on my X8, it's "laggier" than the others, but it's okay.
Did you get it from the real android market? You said that you like their themes... maybe it's, somehow, related to theme you've downloaded and installed?
See you, and good luck with it!
Personally I love GO Launcher, and have never had any problems with it at all. Barely any lag either, but I will investigate Zeam.
There will be a bunch of files (cache, settings, etc.) created on the SD card from GO. You could uninstall it, clear these out, reboot your phone and then reinstall it.
Might solve your problem? Find it does for other apps (as it forces it to gather new data)
P.S. You could have a look on the dev site for help, or even raise a bug: http://golauncher.goforandroid.com/
@Striderzin yes i have download from real android market but not themes in that period of time when i head this problem. I will try once more and0 see what will hapen.
@SirMikey hmm i didnt notice that launcher makes its own folders on sd card thx i will delete them.
I am using unrooted 2.1 zeam launcher works only 2.2 and above -.-
when i installed Go LauncherEX, I stopped receiving SMS on my Stock 2.1 ROM, i don't know if it was GL EX or if it was coincidence.
But i don't like the Go LauncherEX, just try LauncherPRO, use only one homescreen, disable the homescreen caching, use only one dock page, do not use a lot of widgets, and with this, LauncherPRO will only use about 7MB of RAM, and it will be very smooth too.

Scrolling Lag

I've seen this problem come up in other recent HTC devices, just thought I'd point it out for the Vivid as well.
I'm running LauncherPro with just a few icons, a low-resolution wallpaper, and no widgets. It runs silky smooth but the only gripe I have is that when opening the app drawer, 3D or standard, there's an incredible amount of stuttering and lagginess. Scrolling is not smooth, either.
The only other instance of crappy scrolling I have found on the phone so far is in GO SMS Pro; scrolling up and down conversations and also in the settings menus shows an apparent amount of lag. Nothing to cry about, but still there.
Otherwise, no performance issues at all on my device. Oh, and my previous complaint about the data speed being almost nonexistent - it's fixed. Turned out the phone was trying to sync all three of my Google accounts at one time.
Try a different Launcher? LauncherPro Might have an inherent flaw with HTC Devices possibly. Give GoLauncher a shot and see if there is any difference.
Yeah, I'll do that now. I personally dislike Go Launcher but I'll try a few others and see how they perform. I don't think a launcher would affect the lag in GO SMS, though.
EDIT: Lag is still present in Go, Zeam, and ADW launchers.
Interesting. Good to know. It is possible I suppose that they are not correctly optimized for the resolution and Screen size. Although if it is having problems with other HTC Devices my only conclusion is that it is because of some sort of Software issue between HTC and Custom Launchers.
Yeah that's all I could think of, how maybe the high resolution has something to do with it. Hopefully, that's right. Then it would just depend upon app makers to update their apps.
I see no lag what so ever on anything on this phone...
maybe ya got a bad unit?
Are you using GO SMS or any other launchers besides Sense?
This whole rom is slow in comparison to how my inspire rom runs....sad....but thats at&t for [email protected] software. But as soon as we have root,Ill be cooking my own for this,until then it can sit in the box...lol

I have the lag you speak of and its driving me up the wall. Why did I give up my galaxy s2

Calm down, it's not such a big deal. It could because of the greater resolution, much higher than the Samsungs. Not a hundred percent sure, but really. People need to stop being so nit picky and judgmental. It's a phone. In this world, they ALL have their quirks.
No lag what so ever here. Running Launcher Pro Paid Edition. I have 3 homescreens with 4 Columns and 5 Rows, and have 4 Widgets. 3D App Drawer with 5 columns.
Tried ADW EX and Go Launcher and found no lag present as well.
Once a debloated Rom is released everything will be resolved. But for me, haven't had any lag what so ever.
Hm. I wonder if the paid version would make any difference on my device. No lag in the drawer at all? What about in downloaded apps when scrolling?
No problem with anything on launcher. Smooth to me. I've came from an Atrix, Infuse, Inspire, SGS2 and notice no difference. So I've had my share to compare to.
I like the paid version because of the resizable Widgets.
I wonder then, what could be causing it on my phone..
I just tried the latest ics launcher, wow, the first few were kinda sluggish but the latest update is a breeze. There is no lag what so ever and the apps even open instantly with this launcher. I think ics luancher installs itself in a different way, i dont know why but it is smooth as butter.

I just downloaded the new ICS Launcher as well. Seems they've updated it really recently because I tried it on Monday and it wasn't nearly this smooth. Drawer fly-in is amazing, but now the scrolling through the apps is laggy. The changelog did say it was completely rebuilt.
Maybe it's a memory thing? LauncherPro was the very first thing I ever installed on the phone out of the box, and I think I recall that before I installed any other apps, it was running flawlessly.. low memory maybe, but I only have like 10 other apps installed. I'm back to LP for now since I don't really mind the drawer lag that much. I just switched to the 3D version and fly-in is working fine, but now it's the scrolling that lags more than the regular drawer does lol. Can't win.
I know it sounds silly but it could be something as simple as an app icon causing the lag. I had installed something from the market and I noticed lag (this was on my Inspire) and after I uninstalled the app it went back to normal. I reinstalled the app and froze it with TiBu and the lag was still gone... unfroze and lag was back.
YMMV

Yeah I believe you, good point. I'm just going to go through deleting some apps and see if any of them are the problem.
UPDATE: Alright, I just did a factory reset on the phone. As soon as it booted up, I added my primary Gmail account. I went to the Market then closed it so it would update. Meanwhile, I synced my Google contacts, Gmail, and calendar. When that was done, I went back to the Market and downloaded GO SMS - the scrolling lag there still persists. Then, I downloaded LauncherPro (unpaid) and went through opening and exiting the app drawer multiple times - seems the lag is gone. Every now and then, opening it will show some stuttering, as will closing. But it's not every single time like it was before the reset. Perhaps it was something to do with memory? It does not lag on scrolling at all, only during fly-in and fly-out.
UPDATE 2: Never mind. Now that I have changed the default number of homescreens from 3 to 5, it lags every time on opening and closing. Just not on scrolling, yet.
