[Q] Blank screen after unlock screen - Lenovo P780

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.

Home Screen Button Problem

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

[Q] Tray Icon Issue please help

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

[Q] [FIXED] DirectDial Shortcut Not Working for Go/Apex Launcher?

Keep getting a 'Unable to access application, please restart Go launcher', when I tap on a Direct Dial Shortcut on my home screen. This happens for both Go and Apex launchers. TW works ok.
Weird thing was, it used to work when I got the phone. Anyone with similar problems?
I've been using Apex free for two days but not had an issue yet.

I have been using NOVA launcher and have the same issue. When I hit the direct dial widget I get a small message saying "app is not installed". If I clear defaults for the phone app then i get a choice between phone and skype, then hitting phone from there works. But that is definitely not a solution.

Yup, installed Viber and the choice menu pops up. If I select a default, I get back the same error message.

I have the same problem with the direct dial widget for all of the 3rd party launchers. I wonder if it's a permission thing on the Samsung that was not implemented correctly.
I had no such issues with 3rd party launchers on my HTC One-X.
Hit on the bulls eye! I have googled same problem and came directly into this subject. I also have a Galaxy S III and use Apex Launcher instead of memory eating monster Samsung TW; I also install Touch Pal contacts and dialer since Samsung has not been able come with a decent T9 dialer for ages. Anyhow, the problem is direct call shortcuts do not work on my device neither. As for detailed information, I use Omega v4.0. Also note that, I have recently used Apex Launcher on my Galaxy S II with I9100XWLPG (4.0.3) and did not have this problem.
I hope someone comes with a solution, it's annoying.
Regards.
In Nova Launcher it is already fixed. I switched until Apex is fixed too.
Any solution to this? GoLauncher still creating problems.
Fixed!
Its Fixed In Go Launcher! Sent them an email on Tuesday, fixed today. Pretty efficient.
most definitely not fixed!
Direct Dial still not working in Apex launcher. Issue reported to them well over a week ago and have received the odd useless email response from them. Not at all impressed with their "customer service"

I got my SIII about a month ago, and direct dial never worked on Launcher Pro. Did you have to reinstall or something?
Hi, I've a GS III i9300 with Go Launcher and my direct dial refused to work.
Finally, I've managed to make it work :victory:
My exact problem was : I managed to have a direct dial icon on the desktop, and it turned "green" when I clicked on it (everything's normal so far), so it should have worked, but nothing happened, the screen stayed on the desktop like this.
I'm pretty sure the problem can be different for each configuration.
Here are few steps you could follow to have a better idea of your problem.
1/ Be sure that the problem comes from the launcher you have.
To know that, it's very easy, just install a home switcher, like Home Switcher from the market (Link here).
2/ Then go to your apps, click on Home Switcher then launch the default TouchWiz launcher (if you still have it, or another launcher you may have installed)
3/ Now your are in another launcher, so try to add a direct dial icon on the desktop (The usual way is to make a long press somewhere, then you choose apps & widget, then you search a bit between the widgets you get, then long press on direct dial (or speed dial), you place it somewhere, then you select a contact from your list)
4/ Try this direct dial icon. When I tried, it worked directly, so I knew the problem was somewhere around my Go Launcher.
If it's still not working for you, the problem isn't -probably- coming from your launcher !
(Now, you probably have to search somewhere else, like on your rom/kernel...)
5/ If it's working for you, I think it's good news.
Now you can probably go back to your launcher (Go Launcher in my case) and try some things.
Like configuration/parameters --> more --> applications manager --> download --> search for "Go Launcher EX" (or your launcher)
Here you can try to "Clear Defaults", "Clear Cache" & "Clear Data". (Caution : Clearing the data should revert the application back to it's state as it was when you first installed it)
Then reboot your phone and check if it's working.
6/ If it's not. The problem can be another app you've installed that's messing up your Go Launcher.
In my case, I've installed a great app, X Privacy (The Xda topic about it here) that allowed me to feed any app installed with empty/anonymous data.
In this app, you can set & restrain exactly which part of the phone you've turned anonymous (accounts, call, contacts...) for which app.
I had restrain everything for Go Launcher, that's why direct dial wasn't working anymore. I just had to uncheck the part "call (phone, sms, mms)" concerning Go Launcher in X Privacy and now it's working like a charm.
7/ If you don't have X Privacy installed, the problem maybe comes from another app.
I suggest that you uninstall one by one the apps you suspect to mess up your phone, and keep trying.
If you've a custom rom, you may seek help on the dedicated topic.
Good luck !
Found the solution..!
Whoever's havin' the direct-dial widget problem- I had the same problem & after a lot of head-scratchin' & tinkerin', it occured to me-
Go to Settings>Developer Options & see if the option "Do Not Keep Activities" is checked. If it is, uncheck it.
You're good to go..!
Direct Dial App Not Installed Error - Fixed
This is an old thread but decided to answer it here for others searching. I found it on a thread overseas.
Go to Settings/Apps/ scroll to and select your launcher Apk. Select the "Permissions" section and see whats not allowed and it will answer your questions. Enable Contacts, Phone at least. I enabled all of mine.

This worked for me in AIO Launcher. Needed to give phone permission. Many thanks.
With Nova Launcher, this started happening for me after a recent android system update.
None of the above solutions worked.
All my direct dial icons were previously created by going into the contacts app, selecting the contact, and adding to the home screen.
I was able to get it working, by long pressing the nova background - widgets - contacts - direct dial.
So, just adding it this way, somehow fixes it.

[Q] Problems With Action & Apex launchers in HAM2

Just wondering if anyone here has tried using Action, Apex, or Nova launcher with HAM2? I've installed both Action and Apex launchers and neither one will run reliably. With Action, it did run for about two weeks, then just stopped. I re-installed it but it never ran properly again. Periodically the app drawer would disappear, and the apps on the home screen would re-arrange themselves. The list of apps that can be accessed by swiping from left to right also disappeared. Apex launcher worked for a short while (meaning a few minutes) and then the widget that I have on the home screen disappears and the apps on the screen re-arrange themselves. Some apps show up on a different screen. If I leave home page and open an app or if I open an pp on the home page, it depends on how I return to the home page as to whether the widget disappears and the apps re-arrange themselves. If I return to home page by pressing the home icon, then everything is changed when I return. If I return to home page by pressing return button, then everything remains the same.
My Ascend Mate 2 is Model MT2L03 with 16 GB internal storage and a 32 GB SD card. It has Android version 4.3, Emotion 2.0 Lite, and Kernel version 3.4.0. Apart from the launchers mentioned above and hiding the notification bar to provide more space on the screen, I have not made any changes. I'm not sure whether the problem I'm having with the two launchers is unique to my phone or whether it's a problem with all HAM2's. Would appreciate any feedback.
I have been using Nova since day one with my HAM2, and I have had no issues at all. Runs super smooth, and everything works as it should. Maybe give Nova a try.

OK, thanks for your reply. I'll give Nova a try today. If I have a problem with that, then I think there is a problem with my HAM2.

It's possible the power saving modes in the HAM2 are causing issues. Try using the phone on regular power mode, not endurance or smart.

OK Netrunner, thanks for the tip. I've been considering switching to normal mode anyway. This gives me a good reason to do so. I just switched the phone to normal mode. I'll post here if I have any problems with Nova launcher. Thanks.

make a backup of your current rom before you try the following:
1) reset the app data for your launcher and redo it
2) try a factory reset.

I'm using a MT2L03 on 4.3 and have been using Nova since nearly day one myself, haven't had any issues. Sometimes I forget I have a launcher and that it's not stock built into the phone, haha I had issues with Apex at first too, + it was lagging, guess it doesn't like to play nice with our phones.
Been using Nova since the first day... It's solid and no issues

Problems With Action & Apex Launchers in HAM2
Hi guys. After reading the replies to my original post here, I installed Nova Launcher and have had no problems since. Thanks for your suggestions.
I'm an Apex user and have had zero issues.

Almost all apps (including launcher) crash

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??
