SM-N910F Android 6.0.1 App system app question - Upgrading, Modifying and Unlocking

I'm looking to remove all functionality for the phone part, such as carrier, sim & network stuff. Along with the phone.apk & all dependencies. The reason is, I'm going to fit it into the car as a media player. Its all working great. However I know if I manage to remove the apps that make the phone a phone & not just a small tablet. The battery life is immensely long & it boots up in seconds. So far, the phone boots up in exactly 4 seconds from the moment Samsung logo appears & I can leave the phone with the screen off fully charged for well over a month & still have juice. But the issue I've run into, is an annoying pop up about 15 seconds after the phones fully booted saying com.android.phone.apk has stopped responding & click OK & it goes away. Now, I've scanned through the phone & I cant see anything what comes to mind that phone.apk id dependant on or needs phone.apk. So I'm wondering if anyone knows of what system services or whatever thats reliant on phone.apk running that will cause this to pop up? I've had a few guesses at it & ended up disabling the wrong app that prevented the phone from booting. After 18+ reflashes & retries... I figured its time to ask lol
Thanks in advance!

t-mobile HTC desire won't shut down

apologies if this is covered elsewhere.
anyone else got this problem. I read somewhere its quite common. My Desire will not shutdown. everytime I have to hard reset by removing the battery. If I shut just after it has started it will work but after a short length of time if I try shutting down it will not.
This is quite annoying. I'd rather not send back if I can avoid it. I recently received an OTA update from HTC but this did nothing for it.
I also have the problem with application launcher but quick uninstaller is a satisfactory work around. otherwise a great phone which I would recommend to anyone apart from this issue.
I had a very long shutdown time took several minutes to turn off. As I removed (see my comments regarding memory) most of the apps I had installed myself this prob is gone. So it must have been one of the apps that didnt allow the device to turn off.
Its as Jannen said, Have you ever experienced a long shutdown with windows? Its exactly the same thing with Android. Sometimes it struggles to shutdown the OS efficiently. I think its something we are going to have to live with, or you can get a task killer (app manager) and kill all running tasks before you shut down your phone.
But i must say it has not happened to me since i have been using helixlauncher2, so it may be a Sense problem?
JD
ok I treid killing all processes on taskos (except sense which is in the ignore list) and it shut down in about a minute. guess I can live with that...
android is a bit windowsy at times. But in a good way if you know what I mean. love the customisations and can live with the occasional process crashes etc... that this means
yeah had the same problem, sometimes it takes about 10 minutes to shut down.
sometimes killing all apps works, tho sometimes it doesnt.
someone also said to unmount the sd card first.

Random Restart

So far today, my Evo has reset itself about 4 times. That is within the past hour and a half. I've had it since Monday and had no other issues with it doing this until today. The only app that was added in the past 24hrs was the Wireless Tether for Root app. I don't know what or why this is happening. I've just uninstalled Unrevoked, Superuser Permissions, the Overclock Widget, and the Wireless Tether to see if that is causing the issues. Anyone else have anything similar to this happening?
Also, I changed the "always on mobile data" setting to off yesterday. That increased my battery life dramatically. I was able to leave the phone on for a solid 11hrs with it still having 60% charge left. Then today, before I changed any settings at all, unplugging the phone from the charger for about 2hrs has resulted me in being down to 45% battery. Could mobile data always on being off cause the rebooting issue?
Same thing was happening to me when I unchecked that. Checked it back and all rebooting issues went away.

Since I posted that message I had two more reboots. Just ticked always on mobile data back on and am waiting to see if that stops it...
EDIT: No more reboots since reenabling mobile data always on...weird
I've had the always on data feature turned off since day one to conserve battery life and i had not experienced the random shut offs until yesterday. Since yesterday however my phone has restarted itself no less than 20 times. Several times while I was sleeping so this is defiantly a real problem but I dont think its related to settings. ill be contacting HTC tonight
I have had always data off, ticked it on this morn. And started getting the reset issue...

Random restarts are often indicative of the battery not sitting in properly.
Remove the battery. Scratch up the contacts. Insert back firmly...
I am also having this same issue. I turned my phone off this morning because i wouldn't be using it and then i turned it back on in the afternoon and then my phone just started randomly restarting itself. There is no rhyme or reason to it. It has just been happening all by itself. It has probably happened 10 times in the last 4.5 hours.
I took the battery out for a minute and put it back in to see if it will stop the issue, but i'll have to wait and see. However, when i did turn the phone back on i got a weird pop-up message on the main screen that said something to the effect of, "Operational failure, please use su command." Then it faded away. Anyone know what that means?
As mentioned above, turning always-on mobile back on, took care of my restart issue.

I'm getting the same issue. At first i thought it was ATK, so i uninstalled that. Then I though it was lookout, so I disabled that. But it still keeps happening. I have mobile data off too, but for days, and it hasn't affected it one way or the other.
The odd thing is, I was running xiiLive Lite last night streaming the radio all night, and my phone stayed up the whole time, while plugged in (at least 8 hours).
I don't know what the deal is, but my phone goes about 24-48 hours without a spontaneous reboot, and then it will start doing it 4-6 times a day. Anyone have a good logging tool would be nice, as I'm somewhat new to Android.
Thanks!

I had mobile data off for a few days with no reset issues. Then I installed a few apps from the market (not the ones you mentioned) and then the resets started. I uninstalled the newest apps but the resets kept happening. Then I turned mobile data back on and no more resets in the last 24 hours.
my evo is randomly rebooting and I never modified the settings that some of you are talking about. My also gives me random issues where when i try to open an app it will open for a split second and close? I am also having my phone lock up on me several times a day and i have to pull the battery to reboot it! I took it back to the sprint store and they insisted on reloading the software on the phone and it made no difference.... does anyone have any suggestions or similar issues?

I had the apps closing after a split sec too but I found out that it was for apps that didn't play nice with the snapdragon cpu; like the Gameloft game Nova and a few of their other titles.
for me its stock apps like the navigator, video player etc. I am thinking i might have a defective unit.

Yup! That does sound strange! Did you root your phone? I'm rooted and all the stock apps that I've tried, seem to open and work fine.
nope! not rooted, 100% how it was out of the box. Luckily my pre was still active so i video taped it freezing up and stuff so im going to show the tech at the sprint store so hopefully they can order my replacement.
I also have a fully stock phone, some apps installed, but none recently, and yesterday it rebooted itself, twice more today.
I haven't changed the settings mentioned earlier, and haven't done anything I can think of that would cause the rebooting.
I am also having issues where I can't get an IP address on my wireless network, but I'm not sure it's related. I just noticed these 2 problems in the last 2 days, and it's the only thing I can think of that's out of the ordinary from the weeks prior to this happening.
I think I'll take it to Sprint tomorrow and see what they have to say.
Keep us updated on what happens. It seems to take a day or two for symptoms to start, but when they do it goes crazy rebooting!
...more discussion on this issue has been going on here too: http://forum.xda-developers.com/showthread.php?t=702379
I'm not a professional android user and don't know much about it yet, but mine's rebooted a few times as well. I haven't rooted my phone but the ONE thing that seemed to have resolved the continuing issue is doing a hard reboot:
Menu > Settings > Privacy > Factory data reset
It's been 4 days and hasn't rebooted since.
EDIT: It's been 6 days now and still no reboots.
Angry Apps Eating my RAM!
I think what everyone is missing here that maybe the root of the problem is low memory.
I'm not talking about storage on the SD card. I"m talking about the memory the OS has to run.
I've fought long and hard with this low memory problem seeing as I have owned a g1 for almost 2 years.
THERE IS NO REASON THE EVO SHOULD EVER GET DOWN TO UNDER 30MB OF SYSTEM RAM!
I equate this issue to the same issue many people had with Windows computers and applications that start up in the system tray! We don't need most apps to run in the back ground on start up just in case I want to use it. The few seconds of time it shaves off of starting up the app is not worth the slower OS boot up (applies to Windows mainly) or the major slow downs they cause the OS's to have.
I don't need Sprint TV running on boot!
When I used a clean slate scene I still have all of these same issues. Random reboots, slow OS and apps, ect.
I have no idea why Android would allow that much RAM to be used for background apps. I don't understand why we have no way to see what programs run on boot unless using a 3rd party app.
Most apps are so crappy that they run in the background all the time and have no way to toggle if they run on boot and I'm not talking about apps that modify something all the time I"m talking about apps that ONLY need to be running once you open them. An example would be Swipe, I understand the need for that app to run on boot. It modifies the OS keyboard and would need to be running in order to work correctly when ever you enter any text field that pops up the keyboard for input.
An example of programs that don't need to be running on boot or should at least give you an option to toggle boot start up are; Sprint Navigation, Sprint Updater (No idea what this is for), Updater (Android?), Sprint Zone, doubletwist, SprintTV Widget (I'm on the clean slate profile with NO Widgets), VoiceMail (I use Google Voice, is this needed?), Sprint Football Live (It's not even Football season!), MP3 Store (I have yet to use on the EVO but is running just in case, thx), as well as many others.
I have 35 apps running in the back ground! WTF? Thanks ****ty app devs and bloatware Sprint!
Have fun try to find options for each app and figuring out each service to know what it's tied to so that you can have a phone that it powerful and run smoothly.
It really shouldn't be this hard or as much of a pain...

This is where I am so lost with Android. I read many blogs saying Android does not need a task killer and using one will only make your system slow down. Well I tried one anyway because it's in my Windows Mobile nature to do so (old habits....). I noticed that I too had 35 or so apps running in the background and I thought that doesn't sound good, I wanna kill them all. But then what Android pros keep telling me is to let them be and that the OS will kill them as needed. But from what you're saying, it sounds like the OS doesn't always do a good enough job. So my confusion and learning process of Android continues......

[Q] Evo won't stop randomly rebooting and having USB problems

Hey guys, so lately I've been having this really annoying problem where my Evo won't stop rebooting at random times. It usually happens when:
I'm using an app with data or a game
Right after a reboot I unlock my phone and wait 3 seconds and it reboots again
I noticed that the phone does get hot, but i only left it in my car once so this isn't always the case, although this has started recently maybe it is the heat who knows?
Some of the causes i've eliminated are the rom (thought it was just CM7 but it also happens on Fresh), the kernel (tried stock and savaged zen), and the battery (my primary is an EXTENDED BATTERY I BOUGHT ON AMAZON, thought that this was the problem but the reboots happen on the stock battery as well).
I guess this can come only come down to the hardware, which i guess makes sense because I don't think data transfer through usb is working for me anymore either, or it works sporadically. The phone charges fine on the wall, but when i put it into my laptop every usb port caused my Evo to keep unmounting the sd card. <--- I think the usb port is broken or loose because moving the cable seems to get my Evo to transfer data to my laptop for a short while.
If anyone can help me or have the same problems and have a solution that'd be great because I;m really close to unrooting and going to a sprint store if this keeps up
I wrote a response to someone else who had this question. I should have copied it so I can repost it for people.
What I know is this. I have had 3 different evos and they have all done this. It might be a battery problem, but more likely it has to do with low memory/ram.
If I play a game, watch youtube videos, surf the web, or just about anything somewhat intensive, my phone reboots.
I have tried many times, and things, to figure out what has caused this and the only consistent is that I am low on ram.
I use the application Tasker, and it notifies me when I'm getting low on "memory" it then tells me to go to Menu - Settings - Applications - Running Services. from there you can see what is eating up your ram and quit it, or delete it. I have deleted some of the programs and my phone still reboots, but not as often.
If you have widgets running that seems to add to the problem.
The phone reboots to gain back the system ram it needs to work properly.
If I'm wrong, will someone PLEASE correct me and tell what is actually going on.
This is what I have found. Someone else may have a different idea of what may be going on, but this makes more sense than anything else I've heard or read.

Nexus 5X reboot problems

If you're having reboot problems please post here - if there are problem apps or bad devices out there it would be good to know!
Got a new Nexus 5X yesterday for my partner. Plugged it in and charged all day (oh what patience). 10pm started setup and added account to it. Phone immediately did an update which succeeded. Then it started to install the saved apps from the Google account, about 50 in all. After all the apps were installed I handed it over to her to play and log into all those apps with logins. Tedious.
Within about 30 minutes she tried to take a photo and it rebooted. Then a bit later she was using it and it rebooted again. Before going to be it rebooted a few more times. Then again this morning. There wasn't one particular app or other that was in use when these crashes happened. During the day she saw a message about "Google needs to restart". Also the camera often comes up with an all black screen and can't be used.
I called Google tech support and they wanted to do a factory reset and maybe a cache partition wipe. They would also like to investigate if a rogue app is causing the crashes by using it without any apps installed. Because reinstalling apps is so tedious I decided to have her do a cache partition reset I'm awaiting news. I'm hoping we don't have to do the other... I can't imagine how a bad app could be causing such repeated crashes (well I can, but it just shouldn't happen). That's lame...
It would really help if it was easy to get a crash log and find out the cause - unfortunately unless you're rooted this doesn't seem to be easy, and may well be impossible.
I've been having a lot of similar-sounding issues with my 5X. It's never rebooted while I was using it, but once or twice a day I'll pull it out of my pocket and it will be off, awaiting the unlock pattern to boot up.
The camera has been atrocious as well. I've seen the black screen you describe, tons of rotation lag, hanging, etc. Not just in Camera, but in other apps using the camera (such as when attaching a photo to a Hangout). Hoping this is something software-related and not a hardware problem.
I've had mine spontaneously reboot twice so far, both times I've pulled it out of my pocket and it required the PIN to unlock, then it booted up. I'm a bit concerned, as I have no idea when this happened, and, since it's encrypted a reboot essentially puts me offline until I notice it.
I just now had mine reboot during active use for the first time. I was long-pressing a wifi network in order to forget it (which is another 5x problem I keep having—wifi turns itself off or connects to the wrong networks).
My 5x was working fine and the crashing started happening yesterday...
they only app that i recently installed before the crashes started was firefox... are you guys using firefox by any chance???
Mine is still working fine, I do not have Firefox.
Same problem for me when using Firefox. The phone seems to crash and reboot when loading news websites containing photos and videos.
Not seen the issue when not using Firefox.
I've had my nexus 5x since mid/late November 2015. I've had the problem described below happen prior to today, and more than once.
Today, I cant turn my phone off - it seems to be in the middle of a reboot... the four coloured circles (google logo?) with colours going round and round. I powered it off cos it had started going slow... thought a reboot might fix the problem... but now its not starting and I cant even turn it off or do anything with it.. I've tried pressing the power button, I've tried holding the power button down, and I've tried different combinations... nothing seems to make a difference... (has been in that state of un-useablity for at least 30 mins now)
Anyone else also having wi-fi issues where facebook has an error and "cant connect" ?
I had the same thing happen and returned the phone, it's the only solution I found. I factory reset multiple times, called up Google and they told me to safe boot. Right.. I was completely stock and it rebooted multiple times / day and I know what I'm doing too, for the most part anyway. Got a replacement device and it has not once rebooted no matter what I do. Camera, Chrome random apps caused a reboot, it's not that. It's a defective device and you need to get it replaced period.
I have the same thing and can't sent it back to google because I live outside the US.
I believe it is a manufacture defect as I tried everything with no success really annoying.
Stuck with a brick...

I used my phone completely stock for weeks and had zero issues, whereas I have a friend who ordered and received the phone at the exact same time (likely same mfg batch) and had issues. Difference between us two is that I'm a minimalist and only have about 50 apps installed, and he has a ton that he rarely uses and restores them every time.
I know it seems ridiculous, but having an android phone gives you more customization and your apps more power of the phone, so it's completely feasible for ONE rogue app to destroy performance and/or battery.
You guys might all want to try uninstalling apps one by one and figuring out which apps are killing performance. In particular, check out the running services (developer options -> running services) and see which apps are constantly running, since those are more likely to be the ones causing issues.
For example, I've used firefox (for adblocked browsing) for weeks recently, and can definitely say it's a pretty slow app, so if you're having issues on it, you may want to just use chrome or lightning browser.
I just ordered a replacement as well. Mine would reboot about 1 to 2 times a week right after the fingerprint unlock. Annoying as hell today because I was in the middle of a conf call.

Things get wonky after restarting my Pixel (SIM, time zone, wifi calling, voicemail)

Sometimes, not always, when I restart my phone, things get a little crazy and somehow they must be all related. It happens as often as approx once a week. What happens is the following things:
1- I get an email from Where's My Droid that my SIM card or phone number has changed
2- Network-provided time zone changes to Central European Summertime
3- Wifi calling is turned off (however this doesn't normally stay on for some reason)
4- Visual voicemail in the phone app is missing despite still being turned on
5 - APN is not selected (the circle next to Verizon is empty aka does not have the blue dot in it)
I am on 7.1.2 and rooted. Does this happen to anyone else and is there any fix? What could be the cause?
Edit: I doubt this is related, but since I am looking for general feedback for strange bugs with my phone...
Another thing that happens is sometimes while using my phone, apps randomly reload (lack of a better word)
By reload, what happens is the app does not fully close and reopen. What happens is the app remains open ("heading" bar at the top remains) but the rest of the page I am on goes completely blank and then returns with any previous changes undone.
So say I was writing an email in gmail, the red bar at the top with the back arrow and trash can, etc. stays while the rest goes blank and any text I wrote will be gone and I have to start from the beginning. Usually when this is happening, it continues to happen repetitively for a little while. Eventually it just stops on its own. It does not seem to be related to any specific app (since it happens with a bunch of apps) unless maybe it is related to something like Swype keyboard that is always on.
Does that happen to anyone else too? What is causing this??
If your phone is 128g your nand is bad and you need a replacement. Google is aware of the issue and should swap no problem.
