So this is what happened in short. I used Advanced Task Killer app to kill apps to save battery. It worked well for about couple of days. I was careful in what apps to kill. But after my last boot I unintentionally killed some app/task after which i get a "blank screen".
My phone boots normally. I can view my phone screen wallpaper in my locked mode. But when I unlock my phone I get this black area below my notification bar. Only my notification bar works. The menu, home, back and search button do not trigger anything in the black screen. Incoming call is received but i cannot attend them.
I tried multiple reboots. Took off my battery, sim for a few min and booted again. The black screen wont go away. I did a backup using clockwork recovery couple of days back. The last app i installed was Lookout antivirus.
Can someone please guide me how to fix this issue
I will be out for a few hours. I will respond as soon as I'm back. Thank you
Odin back to JFD Stock, Then root and see if that resolves the issue. If it does, then reflash your rom, do not forget to make a backup and save an extra copy on the computer not the phone.
If Flashing Stock does not resolve, then it very likely to be a hardware problem.
what launcher are you using? if its anything besides the gingerbread launcher or twiz then you are probably accidentally killing the launcher you are using and thats resulting in the launcher having to reboot. be very careful with your auto kill settings or set exceptions for your launcher.
you could adb push a different launcher so when you hit home it would ask which one to use and select the new one to gain access.
Hi i resolved the issue by restoring backup. i think killing launcher pro prevented the home screen from launching. Since I could view other thing I hit the power button and then chose Recovery option. It booted in clockwork recovery and I restored a backup I did a couple of days ago and the restore fixed the issue.
Thanks for your inputs.

Alright so I just got a Samsung Fascinate through a trade here on XDA and everything seemed to be in working order...except for the actual software in the phone. For one, the home button doesn't take me home, it simply takes me to a blank screen. I can pull down the notification bar and everything...but I can't get home to actually access and apps or anything. The only way I can access anything is when I hold down the home button to get most recent apps.
I've tried multiple times to hard reset..battery pulls..everything. Someone please help me out. I contacted the previous owner of the phone and he said you just have to press the home button a little harder...that didn't work.
It obviously works because it takes me to a blank screen and allows me to access the most recent apps..but it won't actually take me home.
Any ideas? Thanks in advance guys
Considering the Hines button is capacitive, pushing harder does nothing.
Is the phone rooted or stock?
If stock, try to Odin fresh stock. If rooted, try a different rom
Try installing a different launcher such as Adw, launcher pro or zeam to see if the problem goes away.
Now it does have a crack, but I don't think thats the problem because when I press it it still takes me to a blank screen so it must work.
And he gave me those options..and said it was semi-rooted? Considering I just came fresh from a Moto Droid I really know nothing about the process. Is Odin like SBF? I just want to have the phone in its original state to see if I even like it first..

I would second this suggestion. Often, launchers can have individual settings for what the home button does (i.e., with Go Launcher EX, the home button can be set to take you to your home screen, and if already on your home screen, pressing the home button will open up a shortcut, app, preview homescreens, etc.). So, by installing another launcher, it my clear away whatever setting is on the phone you got (i.e., launching a blank screen). Another option would be to go into your Setting > Manage Applications, and find your default launcher. Open it, and then "Clear Defaults."
Alright I got it to work by restoring completely with odin and changing the home screen launcher.
Thanks guys! It's much appreciated
This is driving me totally nuts I have been trying for ages to figure this out and can't get it.
Samsung Galaxy S2 Totaly stock unrooted Android 2.3.5
My home screen had 4 icons at the bottom for quick launch.
Phone contacts messaging applications
Contacts is redundant since you can access that through the phone icon as well and I never use text messages so I swapped 2 of them for other apps so now the home screen is like this:
Phone Gmail Whatspp Applications
This is fine right up until I restart the phone
When it restarts all 4 are there until is "scans usb storage" at which point the gmail icon disappears
I have to manualy change my application tray from list back to grid view and then edit to put the icon back and then put it back in list view
The icon will then stay until the next restart
As I say this is driving me up the wall
Things I have tried:
Full factory reset and reconfigure the phone
Reboot of phone with tray in both list and grid mode
Clear data from twLauncher and set everything back up again
With and without external SD card installed in phone
No matter what I do as soon as I reboot that icon is gone and it always appears to be gmail.
And please I don't want people telling me to install a different launcher or to root the phone. I don't want it rooted and I tried the other launchers and don't like them
Dude - Sorry i dont have advice for you..but im sitting with something similiar..
Non-rooted phone..but when I reboot phone, the bottom icons (tray), get replaced by my last downloaded apps..for example, skype, flashlight and astro file manager...
After the phone has finished scanning they all return back to normal.
Im guessing this is some random bug, as I also tried clearing data from TWLAUNCHER and within time, after downloading some more apps, the same problem occurs.
Cheers

Rooted nook on cm 7, after I started using it today, I lost my status bar and soft buttons. I did not go into settings and change anything. Any direction towards some help on adw launcher would be appreciated.
Thanks
Try reboot? I have lost my launcher a few times. My status bar once or twice. A reboot always fixes it. Not exactly sure yet what has caused it. If it happens again, get a logcat or dmesg and post it up for the cm7 team to check out.

try doing the obvious thing first and reboot? i had that problem with beautiful widgets and a reinstall of that app solved the problem. did u restore adw with titanium backup? if u did try reinstalling adw.
The status bar disappearing I believe is a CM7 issue in and of itself. I run CM7 on my phone and it has happened on the phone more than the NT.
Thanks for the responses. A reboot has brought everything back as it was. Enjoying my CM7 tablet and the support on this forum!
Did it force close, or did it just disappear with no error or warning?
If no error, it could have just been hidden.

I'm sure the regular version of ADW has this too but I have the paid version to go off of. You can set gestures to show/hide the "DockBar" and/or "StatusBar". Regardless of wether it was a gesture or a glitch you may want to try this if it happens again:
Long press on a blank space on the home screen.
Select "Launcher Actions" from the menu.
Select which ever you need: "Show/hide statusbar" or "Open/close DockBar"
Then just press the new icon on the home screen to restore the statusbar or dock.
Personally, my status bar disappeared without error. Nothing I did would get it to restart other than a quick reboot. Which I am accustomed to anyhow so it's not really a big deal to me. As for the launcher disappearing, it happened. No error. Reset/restart ADW does nothing. Again, this has happened on my NT, my phone, and a coworkers HD2 phone running cm7 as well. It's basically something that I (and her as well) have just learned to live with. Restarting is quick enough to bring everything back to life.
I've got the paid version on four devices (Two NT's, a HD2 and a G2) and have never seen this. Perhaps it's an intentional limitation in the free version... Just kidding. I'd send the author an email about it. Try the widgets I suggested, I'm curious to know if they work to remedy this. Also check that "Gestures" isn't turned on and configured in the Setting (if that's even in the free version).
I have a Lenovo P780 dual sim since 1 month, bought on Amazon Germany, but shipped from China.
Have rooted it and added many other apps and deleted them when I didn't like them. I use the Apex Launcher. It has been perfect up until today. I wanted to move new app icons into the dock area underneath the normal home screens. I bought the Pro version of Apex Launcher because I thought the added functionality would allow me to do this. Whether or not this upgrade is the source of my present problems, I do not know.
The problem I now have is that once I unlock the screen, the normal home screen is now blank. If someone calls me the phone app lights up and I can pick-up and talk normally, later check my contacts, see the call and text logs. After the call, pushing the "Home" button briefly no longer works to bring back the home screen. Pushing the "Home" button for a couple of seconds brings up the running apps and lets me close it, then when returning to the "home" screen its blank.
Swiping down from the top allows me to seeing the settings buttons such as WiFi etc as it was before. I can click on the "Settings" icon to open the settings, but if I try to change the "theme" the app responds every time that it has stopped working.... Swiping back up returns the blank screen.
HELP please !!!

Hi. It seems to me that your Apex Launcher have one big proble. Try to install free version and see if this have this problem. Iff not this is a problem... Iff the free Apex have the same problem you need to change your launcher. Search another one on the market.

Sorry Stumpy, but I cannot use your advice. Since I cannot see my home screens, I cannot launch any apps. When I power on my phone I have no access to any apps. However if an email arrives, the GMail email app starts and I can then read and send emails. If I receive a telephone call, the native phone/contact/messages app starts and then I can also use these apps. But I cannot start or see any of the other installed apps, unless it has been prompted to start from outside my phone.
I have backed up all data and applications to my SD card using Titanium Backup before this problem started. I have reset the phone using the internal red button, used the settings menu to restore the data and apps, but nothing helps. I can change the Wallpaper using the Settings icon I can see when I swipe down from the top of the phone but when I try to change the Theme, the Settings app responds with "Unfortunately System UI has stopped". (This always happened since the phone was new - so I then downloaded Apex Launcher to go around this problem)

Hi again. Please tell me what rom do you use. Do you have custom recovery like TWRP or CWM?

Hi Stumpy
I managed to get my phone back!
I used my desktop computer to send myself an email with a link to another launcher (Go Launcher). When the email arrived on my phone I could then click on the link which gave me the chance to open the link using Google Play and then install the new launcher. Once the new launcher was installed, I could see everything again, except that I then needed to put all the apps back in the right places. Wow am I happy !!
Thanks for your time and trying to help me!!

I am glad that you manage to resolve the problem. Be carefull next time when you spend money on apps. Try free versions first time and install custom recovery for your phone. They are the best thing for backup.

Hey all,
Just got my new OnePlusX and the first time I turned it on it prompted all the set up screens. I had to skip through them all because the keyboard would not stay open. It would open and then immediately minimize. Not a great start but no problem, I'll add my accounts and connect to wifi later.
Once I get into the 'home screen' I could see my status bar at the top but no icons and no way to access the app draw. I pressed the capacitive buttons and opened the notification slider which both worked and eventually got into the play store. From here I installed an app or two and got prompted to do a system update, which I did.
After the update I was hoping my launcher would work.. it didn't. The home screen is a black screen with the status bar at the top and no icons - the home button seems to do nothing when I'm in an app and press it.
I installed a third party launcher which worked - I now have a home screen and app draw. However, after opening an app, it crashes after a second or two (chompSMS does this as well as messenger, phone and contacts which are stock apps).
Does anyone have any information about this, what can I do here?
I know one option might be flashing a custom rom but being a brand new phone that should most definitely not be something I have to do to be able to call and message people..
Update: I ran a factory reset and all problems seemed to be resolved now. Not sure what was going on but I guess something happened that a reboot couldn't fix. I'll leave this post in case it helps others.
Have you done a factory reset after the system update??
