[Upgrading, Modifying and Unlocking] Unbroken Motion:
Before I start, I would like to say that i am aware some apps just wont work as a system app.

I recently rooted my Samsung Tab 3 7.0 lite and more recently have flashed a debloated/deodexed/rooted ROM onto it using TWRP. I am now in the process of modifying the ROM, having uninstalled a few apps such as TouchWiz, Video Player, and samsung keyboard, and then installing Nova Launhcer, VLC, and Google Keyboard.

however my problem lies with the Google keyboard, I had to move it back to the /data/app directory after finding that it does not run when in the /system/app directory. All of my other apps work fine under system and the launcher has no problems either.

Are there ways to configure apps to not be removed even if I were to do a factory reset on my custom ROM? This would be very helpful for me.
[Upgrading, Modifying and Unlocking] abees:
Google keyboard wont be working as a system app i think you can try using gapps nano package or make a flashable zip of Google keyboard(i personally tried this)

Hi,

with my earrings (large piercings) I always touch something on screen while in a call, can the screen be deactivated/switched off/locked during a call?
[8125, K-JAM, P4300, MDA Vario General] d0ug:
Once you have started a call, you can press the power button to turn off the screen, the phone call should stay active.This works in WM6 for sure, im not sure about WM5
[8125, K-JAM, P4300, MDA Vario General] urmelchen:
Works under WM5 as well.
[8125, K-JAM, P4300, MDA Vario General] Azimuth21:
another option is the application phonealarm, it has the ability to turn off the screen automatically when a call connects.
[Galaxy S6 Q&A, Help & Troubleshooting] insomniacandroid:
Hello,

I have some questions about KNOX:

1) In what part of the memory, files in KNOX are saved? Are they accessible from PC by connecting USB cable after unlocking it?

2) Is there a way to hide apps in KNOX? They are visible in the applications list and in RAM or battery usage.

3) By mistake I deleted KNOX app. Are the files inside lost?

Thanks in advance.

I rooted my Galaxy Tab 10.1 Wifi and flashed 5.1.1, used Odin

My kid deleted SU.

Why don't you download the rom and gapps again and flash them with twrp instead of Odin on your pc. That should solve it.

Hello

I have a problem. When my S3 reaches under 20% battery, the screen start flickering, i lose the network and the phone closes. When i open the phone again my battery is at 30-40% without charging him, the screen flicks again and the phone closes as i described you. When i connect the charging cable, the phone starts to charge from 0%.

It isn't the battery foul because i change my battery with my father s3 battery which works fine and i have the same problem .

I have installed on my phone this custom ROM : http://xdaforums.com/galaxy-s3/development/rom-qs-i9300-kk-t2755841

hey all :)

so my device is rooted and lately I've been playing around with NFC on my s5 mini. in anticipation of my new nfc implant next week

ive got an app called nfc lockscreen OFF enabler for x posed and have been scanning various things including my passport.

every time i scan the passport its a different ID number which means that way its impossible.

however i was wondering whether there is something i have to do to get it to stick to one ID when it scans

id love to add my passport to the list of approved nfc devices to unlock my phone.

securit wise it would be great because its my passport and i always have it with me.

plus you gotta admit unlocking your phone with your passport is pretty badass

so any ideas?

[Galaxy Note 4 General] kazbluesk1:
I have a Note 4 Sm N910L from Korea. I live here in Japan at the moment. I bought the phone properly over Amazon and its new. I bought a data sim for it and it was working perfectly for about 7 weeks then one morning when I woke up there was no signal I have tried everything - updated from 444 to 501 then downgraded again UP and DOwn Maaany times. If I go near the Docomo store I can get connected again and it will stay connected for the 3km back to my home and then go off again when I reach home and not go back on - so I know the hardware still works ( I guess). It now just continually says Limited service or "your card is not authorised to use this network". Ive tried many other sims in the phone, none work.

If you can give me a step by step COMPLETE guide with links to any files I need to fix it, I'll pop 50 dollars in a paypal account the same day I can make my first skype call again!!! First person's info that actually does the job gets the money.

Love my phone and Im absolutely &%$'ed without it.

Hope you can help (the wife is out buying some rope and a straight-jacket as I type)
[Galaxy Note 4 General] DaReDeViL:
I loved the way you exposed your problem. I don't come here with a fix but only with few suggestions (so I don't deserve the 50 bucks) :

- check the pins of the sim slot

- check the back screws also and tighten them a little bit

- in network settings try to manually set provider and also choose only one mode (no auto 2g/3g/lte) preferably 2g only

[Galaxy Note 4 General] iridaki:
It has happened to me with another phone. Turns out my SIM had failed, so it needed to be replaced. Sometimes it happens and it's quite easy to get a new one, so that would be the first thing I'd do if I were you. I hope you fix the problem soon!
[Galaxy Note 4 General] kazbluesk1:
Thanks but I tried the sim contacts I didnt notice any screws loose (except my own of course) I'll check (though not hopeful). I appreciate any suggestions.
[Galaxy Note 4 General] kazbluesk1:
Iridaki, thank you. I ve tried 4 other sims from my provider in it and they dont want to work either. I feel it is more a software problem as it was alright when i went to sleep one night and the totally banjacked when i woke up in the morning. Im not sure though, just a noob at all this. Thank you for trying to help though.
[Galaxy Note 4 General] kazbluesk1:
I just looked at my settings and i am unable to find any page where I can choose 2g or 3g or 4. When I rooted the phone a few days ago I remember downloading phone info which let me choose but that made no difference. Now my phone is unrooted again.

Thank you though googy
[Galaxy Note 4 General] iridaki:
Ah I see.

I think I know what's going on.

The N910L supports the following frequencies: GSM 900/1800/1900, UMTS 850/1900/2100 and LTE Band 1, 3, 5, 7.

Docomo don't use GSM at all, instead they use UMTS 800/1700/2100 and LTE Band 1, 9, 19, 21, 28.

Basically your phone is not designed for the Japanese market, as it only supports two of the eight frequencies used by Docomo. The reason you had signal and still have around their store is probably because there's a tower that supports the UMTS 2100 or LTE Band 1 frequency. So you either moved recently or perhaps you didn't but one of the nearby towers was switched to a different, unsupported by your phone, frequency.
[Galaxy Note 4 General] DaReDeViL:
In network settings , there should be a submenu where you can change it. You can also directly access it with long press on data connection icon in notification drawer

[Galaxy Note 4 General] azizski:
Service mode

try this code in the dialer *#0011# whenever you have signal it helps you to identify which band you are connected with

After that you can buy a signal repeater that support that band and bring signal to your home since its not that far distance 3km from docomo store : )
[Galaxy Note 4 General] devilxvergil:
are you on 5.0.1 ?

some suggestions for you.

settings>mobile networks, there should be the preferred network type

check your access point names again, or try adding again, sending a message to provider would probably give u the settings. :fingers-crossed:
[Galaxy Note 4 General] kazbluesk1:
Ive not moved recently, and my childrens phones on the same sim plan and provider works perfectly. Also no matter where I go I never get signal - except right outside doccomo shop. BUT phone worked perfectly for 7 weeks before with great signal. Something has changed regarding my phone I think. Maybe my phone got changed to different settings over the air or something.

Thank you
[Galaxy Note 4 General] kazbluesk1:
When I long press I get a tick box for allowing a Data network and the Just access point settings tab. No tab for choosing 2g 3g 4g LTE etc.

Thanks
[Galaxy Note 4 General] kazbluesk1:
Hello Azizski, I checked *#0011# and the top one says DLCH 10736 ULCH 9786

MM Cause 0 IDLE/DISCONNECTED-SERVICE

GMM Cause 0 DEREGISTERED/LIMIT

RCC DISCONN RSSI/TX 89/0

Whatever that all means.

[Galaxy Note 4 General] kazbluesk1:
Hi, I've input the settings maybe a hundred times now - I can do it from memory almost with my eyes shut :) . The settings are the same as what workedfor 7 weeks. The guy at the counter of my provider input them too - they dont work anymore.. There is only one access point that used to work.

Thanks for your help. I stlll feel the problem is something software or update based, maybe the modem has been changed somehow. Or another setting deep inside the phone.

Does flashing an update also flash a new modem and baseband?
[Galaxy Note 4 General] kazbluesk1:
Hi Yup Im on 501. Was on the phone to them 3 times last week - last time for 2 hours - nothing they say seems to work.

Why you dont try flashing kitkat or first lolipop u get whit odin?

Install from Play Store ☆Phone info☆Samsung and check your CSC code than go to sammmobil and download right FW...flash whit ODIN and u will be see... :)

*Oh sorry u allready tried that... Maybe to flash different modem?
[Galaxy Note 4 General] iridaki:
And, just to clarify, your children have Note 4 phones, with the exact same model number (N910L)?

Hi, Yes, I want to try to flash a new modem but Im not sure about the procedure and exactly which files I need. I have tried to flash a few modems via ZOdin but I keep getting a nand write fail. Im a noob at this and am obviously doing something wrong. If you can tell me exactly how to do it I'd be very greatful.

[Galaxy Note 4 General] kazbluesk1:
Hi Iridaki,

Nope they have 2 old iphone 4 s' using the same data sim as me. (iijmio ((basically docomo)) ). Sorry about not being clear about that.
[Galaxy Note 4 General] iridaki:
Thanks for the clarification. But you can't compare your Note 4 with those phones as they support different frequency bands.

I found this on the iijmio website:

As I pointed out in my previous post, the N910L supports the following frequencies: GSM 900/1800/1900, UMTS 850/1900/2100 and LTE Band 1, 3, 5, 7.

Which means you will only get signal when you're in an area where the network broadcasts either the LTE Band 1 or 3G Band 1. And that changes, especially as networks aim to provide LTE support in most areas. So it is not unlikely that Docomo upgraded the network in your area and now uses an LTE Band that is not supported by your device.

The same website doesn't even list the Note 4 as compatible with their SIM plan, by the way.

I know that it is hard to accept that this is the reason behind your issue, as there's pretty much nothing you can do about it, but I believe this is way more likely than something like a setting changing on the phone without your intervention. You've tried reflashing, upgrading the firmware, downgrading, rooting, unrooting, modifying APN... I really think you've done everything that's possible, so it must be an incompatibility of the device with the Japanese network. After all, it was not designed for the Japanese market.
[Galaxy Note 4 General] kazbluesk1:
I think you are right about what you say - what confuses me is the fact that I was getting perfect coverage all over Tokyo for 7 weeks and regularly saw the symbols change from LTE to 4G and 3 G. Something changing on my phone seems more likely than the network all over Japan changing. It is not just near my house where I dont get a signal anywhere now - it's everywhere! I just have a strong feeling it is something in my phone that has changed - not external. And Ive babied this phone so I dont think I knocked or damaged it in any way.

It is very confusing and frustrating.

Thank you for looking up the iijmio band info for me , I'll make a note of that.

Ian
[Galaxy Note 4 General] azizski:
Another methode what if you lost efs data because u downgraded to kitkat would you check if you got an imei code type this *#06#

If imei code exist so probably its modem error i recommend you flash one using oden or custom recovery

Screenshots can be usefull maybe something hidden you couldn't reconize it ; )
[Galaxy Note 4 General] kazbluesk1:
I think it is modem error, or something like that too. I checked my IMEI number and it is there though the IMEI on the about page is slightly different than by *#o6# the dialer one is all the same but ends with a " /1 "

I will work out how to use the screen capture function and how to insert pics over the next hour or 2 (good point - thank you ! )

I tried flashing a modem but it was the wrong one or I did it wrong. Do you recommend any specific file and procedure? That 50 dollars is burning a hole in my pocket and I'd love to get rid of it............. :)
[Galaxy Note 4 General] kazbluesk1:
Hi Iridaki,

I think it is the modem. By your posts to me and your thanks rating I trust what you say. If you were going to flash a new modem to an SM N910l how would you do it? I tried 3 times and each time I got a nand write fail (whatever that is). I did something wrong or chose the wrong file (I am a noob afterall) . So because I idn't do this properly, this, I feel, could be the right answer for this situation. How EXACTLY would you do it?
[Galaxy Note 4 General] kazbluesk1:
I just took a screenshot of my CSC. Does this look normal?

]https://goo.gl/photos/6ax4FgQiUqDoYVPj8

[IMG="CSC"]https://goo.gl/photos/6ax4FgQiUqDoYVPj8[/IMG]

my baseband is different from CSC version and Bootloader version
[Galaxy Note 4 General] iridaki:
OK, what I would do is:

1. Go to sammobile website (I can't post a link because apparently it's against the rules)

2. In the Firmwares section, there is search box to input your model number. Write N910L and select your device from the drop-down menu that will appear.

3. There are 4 5.0.1 firmwares for your phone listed there, choose the latest one (top of the list).

4. Now backup any important things on your phone and do a factory reset. Don't set up the phone again! Once it reboots, simply shut it down.

5. After the firmware downloads (it will take a while, depending on your connection), unpack the file, start Odin and load the firmware file in the AP section.

6. Put your newly factory reset Note 4 in Download Mode and connect to your PC.

7. Click Start on Odin and wait for the procedure to finish.

8. Once the phone finishes booting after flashing, turn it off again and enter recovery by pressing the Volume Up Key + Home Key + Power Button.

9. In recovery mode, do a factory reset and then reboot.

10. Set up your phone again.

This is how I would do a clean install. It is time consuming but you must be willing to try everything by now, I know the feeling! :D
[Galaxy Note 4 General] kazbluesk1:
Yup Id do ANYTHING about now :)

OK, I'm going to do that again. I've done that many times already but I always setup the phone again, maybe not setting up will make the difference. When you install does that re-install a new modem at the same time. Or is that separate?

Thank you
[Galaxy Note 4 General] iridaki:
Yes, the modem is part of the firmware, it will be flashed along with the other components. Good luck! Report back and tell us if anything changed! :)
[Galaxy Note 4 General] DaReDeViL:
As additional suggestion, I'd recommend a FULL wipe via odin and also turn on checkbox for bootloader update. You should backup your data as EVERYTHING should be erased.

PS: if you have an advanced reboot menu to access bootloader menu DON'T use it. Turn off your phone and wait few seconds then use proper keys combo.

Hi Anton. Yup tried both your combinations to get there but when after I enter the codes nothing happens

is there another way to get to HW Test?

I can get to main menu by using 123456789 (phone info app) and that brings me into Service Mode Main Menu 1 Protocol 2 UE setting and 3 ETC

If I click 2 then go to settings on next pane then if I choose system it gives me an option of NV Rebuild but when I select it nothing happens.
