slow boot up & screen rotation - G Pad 8.3 Q&A, Help & Troubleshooting

hi all. I'm new to the site and to the LG g pad 8.3 v500
well, after a successful root via the "kingo" method yesterday, all was well...until today.
1st issue.
v slow boot up. after I press the power button, the "LG" logo comes up, but there is no animation, until 1-2min later. then the animation starts, goes back to the logo and stays there for a further 1-2min with the white whoosh (only words I can describe it) going around the logo. after then it boots up normally ???
2nd issue.
screen rotation. tonight, the screen rotation has decided not to work and lock in one position. I have turned on & off the screen rotation in the settings, with no joy. one thing I did find, when I tried to calibrate the device, after I placed it flat & as soon as I press the "calibrate" button, a pop-up screen appears, saying that "com.android.settings has stopped working" and as soon as I press the "ok" button, I go back to the home screen ???
for both issues, I have rested & turned on the device, with no effect. would doing a factory reset fix this?
thanks in advance for reading this post & any help if given ?

***UPDATE***
i have managed to fix both (and may be more) issues. it was a bit of a drastic move, but i done a full restore back to a previous back-up, that i done before i attempted the "Kingo" root. ok, restoring back to this point, i have lost all the apps that i put on there, and i was expecting to loose the root that i had already done, but to my surprise, the root is still there and working :good:
the boot up time has now gone back to normal, instead of the 4min boot up time that it was. and the rotation from portrait to landscape has also returned :victory:

***UPDATE 2***
ok...my previous ***UPDATE*** was a bit premature. it worked fine all day, until i done a restart after re-installing all of my previous apps from the play store. again, it takes an age for it to re-boot. i have also noticed when i press the volume button (either up or down), instead of increasing the "Music, Video etc" volume, it changes the "Notifications" volume. but the screen rotation is ok this time
i have done a restore and the boot time has gone back to normal, but the volume is still the same. is there any way to re-configure this???
my other question is, is there a way i can DL the original ROM from somewhere. so i can un-root in "SuperSU", restore back to factory, then re-root?

***UPDATE 3***
right...after a lot of installing of apps and restoring back to stock, i have finally managed to find the program that was causing the long boot-up issue. the culprit was "Cydia Substrate". as soon as i un-installed the app, my boot times went back to normal. i have since messaged the author via twitter. lets hope he can fix the issue.
as for the ROM DL. it turns out, that i cant to a simple search. or i was blind at the time. as there is a thread regarding this "HERE"
i also figured out the music volume problem...and im a bit embarrassed about this. because of the above issues, i had not put any music onto tablet or into the SD mem card. so the music apps that i installed, could not find any music to play. so in-turn, the tablet could not turn up or down the music volume, as there was no music install on it. oops....lol
its amazing what a bit of true grit and determination (and a bit of vodka) can achieve...lol

[Q] Recent app screen keeps coming up?

Hey guys! I recently updated my phone to 4.1.2 and noticed almost every time I go to use my phone and hit either the power button or the home button the recent app screen pops up instantly as if you were to hold the home button down. So far I tried a soft reset a factory reset with no luck. The phone worked perfectly before the update so I know it isn't either of the buttons sticking. If anyone has any ideas I would greatly appreciate your help, I'm at the point where I'm pulling my hair out haha
Thanks!!
Did you do the OTA (over the air) update Sprint pushed out, are you on a custom rom, or are you using a non stock launcher? Give us some details and someone, if not me, will help you out.
Also try rebooting. Some users in the past have reported that trying to activate recent apps properly (by holding the home) stopped working and a simply powering the device off then turning it back on fixed the issue. This may solve your issue too.
I see this is your first post, are you familiar with rooting and custom roms? Just curious so we know how to get you through this.
Thanks for helping. I did the ota update that sprint pushed out. The phone is completely stock nothing on it is modified at all. I already tried rebooting multiple times and tried a battery pull also. I am new to rooting and custom roms. Everything else on the phone is working fine but the recent app screen will come up as soon as I turn the screen on. It wont come up if I turn the screen on hit home to go to home screen turn screen off using power button and turn the screen back on quickly, it has to sit for 30sec to 1min for it to start doing it again.
Thanks!!

Anybody got any ideas?
Sorry for the late reply, I work a night shift.
Are you waking the screen up with the home button or the power button. The reason I am asking is because the only way I can make this same situation occur is with no lock screen set, I wake up the phone with the home screen button.
Try setting up a lock screen and see if it fixes the problem.
If it does not fix the problem then I recomend taking the phone back to Sprint to see if they will swap the device since you are not rooted.
If you have a custom recovery installed try rebooting into recovery and wiping cache and dalvik cache then go to advanced and fix permissions, if you only have stock recovery try wiping cache from it. To boot to recovery, power off phone, hold volume up and home then power, let go of the 3 keys when the note 2 splash screen pops up. If that doesn't alleviate the issue it may be a setting with the home key presses, for instance you can change what it does with longpress and double tap, may have gotten the svoice and recent apps mixed up. Try double tapping home and see if svoice comes up or recent apps, also longpress to see which comes up.
I like to break stuff!

This is deff recent update caused i believe. I also have a non rooted sprint device that I just updated, and its doing the exact same thing. Annoying as hell. My device is less then a month old. To explain more on what happens, I have my screen timeout set for 2 mins, lock at 5 mins. Use phone, put it down, wait for screen to time out, pick it up and hit him key once and it brings up the task manager. Not a long press, just a fast press.
I tried to clear the cache with no luck..
I guess that makes two of us for this problem.
I have noticed sometimes when I go to use the phone there will be a blue box around one of the apps. Not sure if its the last app I used but it has been doing this since before the update.
I cant replicate the issue to save my life. When you guys updated something must have gotten confused in the process. May need to download a stock restore of ma7 and start fresh. That would be what I would do if nothing else fixes it. It will erase all you apps and settings and internal storage so back em up. Back up internal to PC
I like to break stuff!
Ok ill be more than happy to try that.. what exactly is ma7 and where can I dl it. Is there anything special I need to know or do to complete the process? I already cleared my my contacts.. google said they were uploaded but apparently not.
Thanks again for the help!!

MA7 is the latest OTA 4.1.2 which would be the update you took prior to this recent apps incident. Look in development for a thread by garwynn it'll have the links to the Odin one-click packages and since you already took OTA you won't need the modem. Just follow the directions in his thread. Before doing it if you have anything stored to your internal storage you want to save back it up to your PC via USB. You'll want to grab the full restore one click so it wipes everything and starts fresh.

Same issue, called Sprint
I spoke with sprint about this today, very frustrating. I learned:
Not all note users are having this problem
they did a reactivation, prl update, firmware check, profile (?) update.
That didn't do anything, so the recommended a hard reset, that's when I flipped out.
They said I may be able to sent me a new phone if the hard reset doesn't help, but would need to pay a $49 exchange fee... then i flipped out more.
possible reasons: I really don't know, here is what i have:
Go Launcher
SD card, inserted a couple weeks after activation
I use Home2 to modify my home button double tap action
Not rooted or anything.

I'm still having the same issue with recent apps popping up upon awake, non rooted sprint, happened after recent OTA update, and have no apps in common with above poster. I have not done a reset yet as it hasn't bothered to that extent yet, and once I get ready to root and really tear into things, ill work it out then I suppose.
I'm having the same issue after updating to MA7. Im rooted, cleared both caches and still going on. When I wake the phone with the home button it wakes up and shows the recent apps, when I close that it take me to my lock screen (wigetlocker)
Edit: Fixing permissions just fixed it for me and also clearing the caches again.
Double Edit: Started doing it again. -___-

I am having this problem to it happens when the screen goes off but does not lock in my experience. I would never pay for a new phone if it is a update that messed my phone up I would have snapped
Sent from my Nexus 7 using xda app-developers app
Solved
I have the Note 2 on Sprint. The update that I got a couple days ago has solved this problem.

Screen gone black - Big issue

I've delayed posting this for quier a while out of sheer laziness.
I wanted to try to change the boot animation after rooting with towelroot. Because I couldn't be bothered doing it manually, I downloaded a boot animation app to change it for me. I was trying to change it to the Nexus Pie BA. Immediately I rebooted it to test if ig was working.
It ran through the first un-animated LG logo, then went (backlit) black. I figured maybe it hadn't installed correctly, so I'd just wait a little longer for it to finish booting up. Eventually I realized it wasn't going to. It was pretty much stuck on a backlit black screen. I knew it was responding because it would vibrate when I hit the nav buttons. When I rotated it, about 30% of the screen was working normally. I later factory reset it, and it booted fine and was working, but I eventually had to turn it off and the screen stopped displaying things again.
What should I do?
I really need to know how to fix this issue somehow, it's been a brick for too long.
Cheers to anyone who can help.

Weird Problem/Crash last night

Last night I set up Watch On - the samsung remote control for TV and STB's, and suddenly the tablet went to a black screen with a white folder option on the left bottom corner and the apps folder icon in the right corner. Infrequently it would flash to the 3rd home page that only had the Guardian news app on (which could also be seen on the black screen), but the screen was non responsive.
Tried turning off (holding power for 10 secs or more), but it didn't respond. Also when holding the power button for a second to get the restart/power off options, as the screen was non responsive they didn't do anything either.
Thought it had bricked itself! Not rooted, totally standard.
Eventually using google found the power, home and volume down action and after 15 secs or so it restarted. Then had an occassional error stating 'set up is not responding'...even though it does!
Can the device be reinstalled using kies? Even if a problem is not identified? I'm slightly concerned by this as never seen anything like this before. Was it just a glitch or likely to be something more severe requiring a return to shop?
thanks
It might of been an app/tablet freeze or some sort. My tab s froze once and I waited 10 minutes for it to respond and it did. So I restarted it and everything has been working fine. It could be that you were low on ram. If it happens again it could be the software in which you have to reinstall/update with kies. If that doesnt work then I would take it to get fix since it could be defective.
how do you reinstall through kies? I can see options for failed installs but not replacing existing installions? I guess a factory reset is worthy first?

I would a factory reset. I forget how to do it with kies and theres videos on youtube to do so. Are you on the latest update?
ok I'll try that first - hate factory resets as it never reinstalls it with the same settings! (using nova...)

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!
Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!
Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?
Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it
The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!

I think my phone is on its last legs

The thing is becoming increasingly unresponsive when something tries to wake it from deep sleep. A few weeks back someone tried to call me, and the screen turned on and flashed the dialer app, but the touchscreen was unresponsive. I'd click "Answer" and it wouldn't register. Clicking it repeatedly, clicking anywhere on the screen, trying to turn the screen off and on, nothing would work. The phone basically froze, only not exactly, because the sound was still playing. Like a minute later, I held the power button down and got the shutdown pop-up which seemed to rouse it out of whatever infinite loop it was stuck in.
This morning, it happened again when my alarm went off. I could not get the damn thing to stop. It happened again an hour later. When I tried to hold down the power button, the phone reset.
When it came back on, a bunch of my settings had been reset. It reverted to the default keyboard and started showing me tutorials like it thought this was my first time powering on the phone. Additionally, the System Updates menu shows I'm on the latest version, but all history of past updates has been wiped out.
I'm getting really concerned that this thing is gonna die on me any day now.

How about factory resetting the phone, starting from scratch re the software installed? Yes, you'll need to reinstall your apps and reconfigure it, but it's like starting fresh. If it still malfunctions, then you can look deeper.

Thanks for the advice, but I ended up grabbing a Galaxy S8+ off a friend for very cheap. So, not really an issue anymore.
