Can I use Tasker to simulate Page Up / Page Down without root access?
I've read people doing it using adb without root access. I've also read that people can do it using Tasker and several other methods, but with root access.

Is it possible to do the same with Tasker (or other methods without involving devices other than the phone itself), but without root access? If not, why so?

This app will not install or uninstall on my phone
I am on android, Sony Xperia M C1904 model. There is an app called "SnapChat" that I cannot install or uninstall from my phone.

What happened earlier was that I didn't have enough storage and after i made enough storage, I tried to install it again, but it tells me I have it installed.

After lots of googling, cache clearing, and removing from my "Apps", this app still would not let me install.

I have tried to remove the listing on "My Apps" from my Google Play Store (it is gone now), and it still tells me i have it installed. I looked inside my phone's 'all apps" and it doesn't even list SnapChat. I had another app called "Sky Night" that I got rid of a while back and through this method I managed to properly "remove it". On the app store, it says I have it installed but it lets me install it again at least. But this one app would just not go away or get on my phone.

For reference I used techniques from here

Error while trying to stream TIDAL from Android to NVIDIA Shield
I just downloaded the TIDAL app on my android phone and tried casting it to my NVIDIA Shield. The TIDAL app has a build in functionality to do exactly that. So I open the app, start playing a song and select the cast to shield action. After that I can see the TIDAL logo on my TV screen, but the song stops playing and the app becomes inresponsive.

As you can see the app grays out everything on the screen.

I have absolutely no idea what is happening here, but maybe someone has experienced a similar issue?

Casting the screen works through other apps, so I'm pretty sure it's related to TIDAL.

I've reset my SHIELD and reinstalled the TIDAL app without any success.

Cannot flash Moto G3 2015 due to "Preflash validation failed" error
I have a Moto G3 XT1550 phone. I had to reset the phone as its UI was restarting on its own after 1-2 minutes of usage. After the phone booted, it asked me to enter the GMail and password the phone was registered with which I did, but the phone failed to recognize the Google account credentials.

I NEVER ACTIVATED USB DEBUGGING FROM DEVELOPER OPTIONS ON 'THIS' DEVICE AS I NEVER NEEDED TO.

I performed "Wipe data/factory reset" and "Wipe cache partition" from Recovery Mode expecting that the stored Google account would be removed. But it did not. Then I came to know that it is called "Factory Reset Protection (FRP)".

Since then, I have tried everything I could find over the Internet - Bypassing FRP, flash Stock ROM (100% sure downloaded a correct one), flash custom ROM, and flash TWRP. All to no use. Even tried unlocking the bootloader (got the unlock code from Motorola's website the same). Even that did not work, saying:

```<code>C:\MotoG3>fastboot oem unlock XCYJ4AZH542XAQWBJYFF
...
(bootloader) Check 'Allow OEM Unlock' in Developer Options. FAILED (remote failure)
finished. total time: 0.016s
</code>```

While flashing any image from fastboot, it keeps throwing a Preflash validation failed error.

```<code>C:\MotoG3>fastboot flash partition gpt.bin
target reported max download size of 268435456 bytes
sending 'partition' (32 KB)...
OKAY [  0.018s]

```<code>C:\Moto G3\Mfastboot>fastboot flash recovery twrp-osprey-2.8.7-test1.img

sending 'recovery' (11170 KB)...
OKAY [  0.400s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
</code>```

I've even tried an article that tells a trick to entering the phone's settings by long-pressing a word in the Privacy Policy of the phone and opening "Define". Long pressing on a word just makes the phone vibrate and not select it.

Even attaching an OTG drive with the hope to copy FRPBypass APK to the phone's memory work as nothing shows up on connecting the OTG drive (as against expected File Explorer opening up).

In a nutshell, I have kind-of soft-bricked my phone. Left with no other option. I don't even expect the Service Center guys to do anything that I haven't tried (expect to change the ROM chip, if ever possible).

Any help, please?

SMS is stuck as "not received" and reappears each restart
Several months ago I received a spam message on my Android phone (nothing unusual there).
What is unusual, is the fact that this SMS is now stuck somewhere inside my phone's messaging module and it keeps "receiving" every time I turn the phone on (including after restart).

I have contacted my SP, and they are not related to this issue. In fact, I tried different SIM, and this SMS is received again for entirely different SIM.

What I'm inferring from this is that text is stuck somewhere on my device marked as "new SMS" forever, and each time phone turns on, it looks into that list, finds it and displays it, but somehow fails to take "new SMS" flag away from it.

The question the is:
Is there a queue(or a file) where I can find that stuck message and delete it manually?

Rolling back to factory defaults do not seem like a good option to solve my problem at this time.

If this matters, my SMS app also always displays "you have 2 new SMS" badge (strange that it displays 2, but it does).

Lenovo S660 with latest available for it official Android 4.4 firmware. Unrooted (rooting is possible).

How to disable fingerprint from opening a locked phone, but enable for applications?
In Android 6.0.1, there is an option to 'Enable fingerprint' in Application lock, but it forces the phone to be unlocked via fingerprints.

Since most likely, the application lock only prevents sensitive data (messages, account information, etc.) from  being accessed/viewed easily, it makes more sense to me to selectively allow usage of fingerprint to unlock apps (and not the phone) because for the phone, a secure PIN/Password makes more sense.

Why is it so? Is there a way to achieve the desired result (using no third party tools)?

Any reasonable answer for huge battery discharge when device is off?
Nearly three years ago I have asked this question. It brought certain attention, but no answer. Of course there is no change in Nexus behavior and device discharges its battery up to 30-50 times faster when completely turned of than when it is turned on, but not used at all.

To my complete surprise, after these nearly three years I have notice the very same behavior in many more mobile devices, irrespective of device type, manufacturer or even operating system.

Recently I noticed this in:

Sony Xperia E,

Apple iPad Mini (first edition),

Microsoft Lumia 640 and 650.

Is there any consistent theory or answer, why it is happening? Why device drains battery at all, when it is (should be) completely turned off? And why the discharge rate is so enormously1 high?

I'm looking for an answer at least partially proven or grounded on some verifiable facts. Spy theories -- that it is due to fact that completely turned off device sends a lot of information to Google / Facebook / Apple / Microsoft / US Government -- are quite out of scope of this question.

1I'd say that even absurdly high, given the fact that device completely turned off can't stand more than 24 hours while turned on, but unused at all (lying on shelf) can last up to a week or at least a few days.

How to bypass restrictions on (system) internal sound recording, rooted 4.4.4 android
I have installed an app called "SCR Pro", it allows to record android screen as video with internal sound, or microphone, or mute.
With youtube as example, it can record video with internal sound and without microphone (exterior sounds) WITHOUT problems.
But with Paltalk or Join.me, when it begins to record, it fails to record the internal sound, it obligates me to continue recording as mute or it stopps.
It says "Only one app can use microphone
at a time. This is an Android
system limitation. Close other app
using the microphone (e.g. Google
Now or Skype) or continue
recording without audio".

What is Android trying to tell me with this pop up about selecting a SIM card?
I have been getting this message for a short time.  Two changes are possibly the culprit:

I switched to cricket from tmobile on a tmobile phone. Shortly afterwards I started getting these.

I have a new ROM. OctOs M, which is based on Cyanogen.

I strongly suspect #1.  I've never seen this message before it started happening, and I don't know what its trying to say.

Phone is a T-Mobile Note 2. When I started with Cricket, it was still inadvertently locked, but I worked with T-Mobile to get it unlocked.

This phone physically cannot use more than 1 SIM.

If you didn't know, "Signal" is an app by OpenWhisperSystems.  Its a replacement sms and mms app. I have deregistered and reregistered with the app, and that did not affect this issue.

I did not do a factory reset when switching to the new service, so I wonder if something is up with Signal?

repacked system image fails to boot
I have a problem where the repacked system.img does not work.

My target device is: DOOGEE X5pro, which uses MT6735M chip.

I am using this custom ROM.

The original files from this custom ROM works fine with the device.

I wanted to change something in the system.img and the following is what I did.

```<code>$ simg2img system.img system.raw
$ mkdir tempsys
$ sudo mount -t ext4 -o loop system.raw tempsys
$ cd tempsys
</code>```

Here I made one change. I didn't like the camera shutter sound so I simply deleted the 'camer_shutter.ogg' file in tempsys/media/audio/ui.

```<code>$ cd ..
$ tune2fs -l system.raw
</code>```

here I check that "Block count : 390111", "Block size: 4096". I multiplied these two values and got "1,597,894,656".

```<code>$ sudo make_ext4 -a system -l 1597894656 -s sys3.img tempsys
</code>```

BTW the permission of the sys3.img is as below:

```<code>$ ls -l
-rw-r--r--   1 chadrick chadrick 1327287648  2월 18 16:09 sys3.img
</code>```

I'm not sure if the permission of the system.img file matters before flashing it to the phone.

I shall proceed just as it is.

After flashing it, it is stuck at the boot logo. I guess while the device succeeded upto loading the 'boot.img' but it failed to properly deal with 'system.img'.

Apparently, could someone point out some things that I may have missed?

BTW, I did the same repack operation WITHOUT modifying any contents in with system.raw file. The repacked system.img still didn't work.

I started with a clean calendar on the phone and the Kies indeed transferred all the appointments and events to the phone, however there is a problem interpreting the dates. Any appointment taking place on a day of the month up to the 12th - the day of the month is interpreted as the month itself, and the month is interpreted as the day. Thus - March 9 becomes September 3, etc. Oddly enough, March 15 stays March 15.

Android IPV6 problem, wifi instability/disconnection
My lg g4 has wifi instability/random wifi disconnection when using ipv6 with wifi.

The only workaround I have found is to disable IPV6 on my phone.

I have already tried reseting/updating the phone without sucess

Is there anything I could do to keep IPV6 (I have heard it's not a very good thing to disable it)
? Maybe change some router setting ?


问:
How to add a custom keymap / keyboard layout to Sony Xperia keyboard?
As far as input methods go, I like the Xperia Keyboard from Sony best.

However, I would like to slightly modify the English keymap. Specifically, I want to add some additional accented characters to the list of long-press alternatives for both "e" and "a".

I don't mind whether I replace some of the existing ones (so that "e" still has five accented alternatives and "a" still has seven) or add new ones; whichever is easier.

Is there any sensible way to do this?

Xperia Keyboard supports many languages which can be downloaded from its Input Method settings, and I presume some of these have several keyboard layouts (as there is an option to choose keyboard layout for your chosen language; I'm not sure as English (UK) only has one keyboard layout (QWERTY) but this option wouldn't make sense if at least some languages didn't have multiple layout options). This suggests that there is a place somewhere on my phone where I should be able to put an input language / keyboard layout file in some format and this would be recognised as one of my keyboard options in Xperia Keyboard settings.

My concern is that this may be in some part which is only accessible by if the device is rooted. I would happily root mine but to my best knowledge there is no known method to root it currently (Sony E2303, Marshmallow 6.0.1, bootloader unlock not allowed).

Ideas?

Disable folder auto-creation in OneDrive under Marshmallow
OneDrive for Android 6.0 Marshmallow keeps adding "Email attachments" and "Documents" folder to my root OneDrive folder each time I open this application under my Moto E3.

Is this something OneDrive-specific or Marshmallow-specific. If I switch to Dropbox, will I be able to fully control what is added to my cloud-folder / block automatic creation of some strange folders?


问:
(SOLVED - partial) Flashing Source Built ROM Fails in TWRP, Invalid File Format
I am new to the development community and have started to learn about building Android from source.  I've successfully built AOSP from source for my Nexus 6P (aosp_angler-userdebug, android-7.1.1_r14).  $make runs fine and I can install system.img and boot.img via fastboot and all is well.

However, the .zip made from $make updatepackage fails when I try to flash it in TWPR, throwing an error Failed to install, invalid zip file format!

After doing some research I noted that $make updatepackage isn't producing a META-INF folder.  When I run $make dist, META-INF is created and I can then $./build/tools/releasetools/ota_from_target_files.zip out/target/dist/ota_update.zip, but that ota_update.zip fails with the same error message in TWRP.


问:
Disabling data limit notifications for disabled SIM?
I have a Motorola G (2nd gen) with dual SIM. Only one SIM at a time can be used for mobile data. I have limited free data on both SIMs. When the first SIM reaches this limit, I switch mobile data over to the second SIM. Everything works as expected, except that the notification about the data limit being reached on the first SIM does not disappear.

How do I disable data limit notifications for the SIM where mobile data is disabled?

I can work around the problem by temporarily setting the limit too high for the disabled SIM and resetting them to the correct amount when I next activate it, but this is inconvenient. It is counterintuitive for a disable SIM to show data notifications.

Corrupt framework-res.apk causes boot loop in KitKat 4.4.2
My device is soft bricked due to a corrupt framework-res.apk, it’s stuck in a boot loop but it can be put in recovery mode.

In recovery it gives the option to install updates via adb sideload and the SD card. Also it has the fastboot mode.

I flowed some tutorials and created this update.zip file with the original framework-res.apk

updater-script

```<code>ui_print("Installing...");
show_progress(0.1, 0);
run_program("/sbin/busybox", "mount", "/system");
package_extract_dir("system", "/system");
show_progress(0.1, 10);
show_progress(0.2, 0);
show_progress(0.2, 10);
set_perm_recursive(0, 0, 0755, 0644, "/system/framework/framework-res.apk");
ui_print("Done!")
run_program("/sbin/busybox", "umount", "/system");
</code>```

Running adb sideload update.zip from my computer transfers the file to the device but after that the device shows a message saying Error and "Installation aborted" without any detail of what could be the problem.

With fastboot update update.zip it shows

```<code>ERROR: could not clear input pipe; result e000404f, ignoring...
ERROR: could not clear output pipe; result e000404f, ignoring....

Alternative Android Date Picker (for Dates of Birth, DOB)
I was wondering if there is any way to call the date picker that the contacts app uses, as oppposed to the date picker that chrome uses.

We've found users struggling to identify how input their birth year, due to the year picker appearing too much like a label.

Does VLC for Android show the true bitrate of m4a files?
I downloaded an audio file in m4a format, which in all other apps (eg. BlackPlayer, Phonograph) shows a bitrate of 32 kbps. But VLC shows 1.4 mbps!! What is going on? Does VLC somehow decompress the M4A music and then shows the original bitrate?

Is there a way to replace the Android system file manager with a third-party file manager?
I'm using an OnePlus 3 with Android 6 (Marshmallow). For me the standard Android system file manager that opens when you want to send a photo or video via WhatsApp is just horrible.

It's slow and you have to click several times to reach your desired folder.

So, is there a way to make a third-party file manager (SolidExplorer for me) open instead of the system file manager? I know I can open the file manager from the system file manager (bottom of the sidebar) but I would like to skip this two clicks.

Does anyone has a clue on how to achieve this?

Google Messenger : Moto g4 / g4 plus does not show links in SMS
As shown in the screenshot (sorry it's in French), Google Messenger does not display links under phone numbers on my Moto G4 Plus (Moto G4 has the same problem).

In this case I was expecting (like my previous phone) an hyperlink on '555507', allowing me to directly call this number.

The same SMS within the same app on another phone (Fairphone FP1U or HTC Desire 500) shows the link.

How can I configure Messenger or Moto G4 to have such links ?

Update after contacting Motorola customer service:
They say it's related to the quotes, but I am not sure at all. I have seen in my history many numbers that do not have quote, and still they are not hyperlinks. My opinion is that they link only when number has more than 7(?) digits.

问:
Why is CPU usage constant high (~2/2/2.5) on Samsung S3?
Short story: Samsung S3 running stock Android 4.3. Was sluggish, turned on "show CPU usage" in developer options and it hovers around 2/2/2.5. Stopping all active apps doesn't help. I see "mmcqd", multiple "kworker" instances, "system_server", "systemui", "surfacefinger" etc. in the related list of processes.

Didn't know how normal this kind of load is for an Android device, so I checked on an LG 4x HD (Android 4.0.3) and there I see usage fall below 0.5/0.5/0.5, so there seems to be a problem on S3.

Update: checked a low end Lenovo A Plus and load there is around 12, yet it's quite responsive. No idea what to make of it. In any case, the S3 is very slow and shows a much higher load than the LG.

Sure, S3 has Viber, all kinds of Google sync enabled, but I'd don't see these in the process list and they're not being used (no user interaction with the phone whatsoever).

So, how to find the cause and reduce CPU load to make the phone more snappy?


问:
Talk to Android Device via UDP via a wired connection (on Windows) - UDP port forwarding & port mirroring (like midimux)
This is a continuation of an already asked question, where the "solution was simple", using a shell cmd in terminal...

android.stackexchange.com/a/60727

This was WAY simpler than I thought it was. I was trying to get this
  working for days now but it's actually really simple.

After you did that, open a terminal emulator window on the device or
  open an adb shell session with the command adb shell. Enter netcfg to
  print out all the IPs and look for a device named rndis0 or usb0 or
  maybe another name, depending on your ROM or device. Simply look at
  all the devices that are "UP" and make sure its not Wifi or Mobile
  data connection, you can recognize them by the device name.

If you think you found the correct adapter (it shouldn't show more
  than 2-3 devices that are listed as  UP and have an valid IP next to
  it) simply send your OSC messages to that IP adress and it will work
  just fine. This should work with about any network protocol.

Terminal isn't on play store, so guess that referred to configuring the device at the (linux/mac?) computer end.

My question pertains to windows, re [Mach's question @ hexler]
hexler.net / forum / viewthread / 1116

[failed attempt 1]
docs.google.com/document/d/1zAnWDs34aO9QRbICYQUlklJlK7ZqiENc5d9SIsxr9v0/edit?usp=sharing

OSC is an 'encoding', not a protocol (the co-author* tells us)

OSC is an encoding not a protocol. Some OSC libraries and apps only
  support UDP for some reason but from the beginning it has been run
  over serial, TCP/IP and UDP. I have tunneled over MIDI too. oscuino
  shows you how to separate the encoding from the protocol.

Because some applications only listen for OSC over UDP there is an
  advantage making the Teensy appear to be a source and sink of UDP
  packets.

SO, it seems it can be done. Just haven't yet worked out how, on either Android OR USB...

I have no rep for commenting, but I hope to ascertain HOW to config usb tethering on droid,and port mirroring - I simply want clear instructions.

Why would google-related service have no Internet, while others do?
I'm fighting with a strange and annoying problem being forced to restart phone a few times each time I left home, even written here a question, effortless. However, I've started inspecting more.

The problem is with Game I'm playing a lot, Ingress. It is a start-up that launched at google. As marking sign of it being unable to connect is that Gmail can't synchronize itself. However, I've started to check. It seems that generally internet connection runs good. I can even run Facebook in browser. Another game I use runs also good, but has problem with refreshing maps.

It seems that I have some problem with internet connection to Google-related Services, which upon hanging, requires the phone to restart, even if otherwise everything is working. I can also start plain/mode, but the success ratio is about 1/3 lower than the full restart.

Is there anything that could cause such a strange behaviour, and is there a faster way than restart or plain mode? Both take a lot of time and are energy consuming.

I'm using Android 5, if that matters.

Trying to restore SMS messages after a factory reset
Before I did a factory reset on my LG G3 I copied everything in the internal memory to my PC (drag and drop over USB) just in case I needed any of it later.

USB OTG on OnePlus 2 phone not working, yet
As I understand it I HAVE to use the original USB OTG adapter from OnePlus before I can make use of the OTG functionality on my OnePlus 2.

But what happens if I connect a USB OTG Y-cable (powered from a USB charger) to the original OnePlus 2 OTG adapter?

This is what I would like to achieve - I'm not sure if the cable is supposed to be used in this manner

[EDIT_1]

Normally you would just plug the OTG cable into your phone and then (hopefully) it would work - But with the OnePlus 2 phone you have to use OnePlus' original OTG adapter in order to make OTG work (That's what I have read anyway) - I'm just worried that connecting 2 OTG items (cable and adapter) might cause problems.
If I could just find a cable like the one pictured above that ISN'T an OTG cable, then I don't think there would be a problem.

[USB Micro-B] to [USB-A female] with a [USB-A male] for extra power.

Hopefully the above would alow me to attach almost any device to my phone and I wouldn't have to worry about the phones power being drained in no time.

I would also like to keep the amount of adapters, converters and cables to a minimum.

[EDIT_2]

Connecting the above USB OTG power cable and/or a regular USB (USB Micro-B to USB-A Female) cable to the OnePlus 2 adapter does nothing. The USB OTG Power cable DOES charge the phone though. I have now ordered two original OnePlus OTG cables from eBay...
Let's see how that plays out...

[EDIT_3]

One of the original OnePlus cables arrived today - It's supposed to be for the OnePlus 1, but I hoped it would work with the OnePlus 2 adapter.

Still no dice...

[EDIT_4]

Better late than never (sorry)...
None of the adapters that I have tried works. Maybe I received a FAKE OnePlus 2 adapter, I don't know.
I officially give up trying to make it work.

Does everything in this "adapter chain" have to support USB OTG ??

This gives me a permission denied error. Here is the full contents of the shell:

App2sd compatible email app
I have a Casio G'zOne Commando C771 phone. It only has 400 MB of internal storage (!!!). I want to connect to my email, but if I use the built in email app, it will very quickly fill up what little storage I have left.

In most cases, I have to use "App2SD" apps and never use the built in apps that come with the phone (outdated, and if I even download the updates they will immediately take up that little bit of space - so I only updated the Play Store and nothing else). I have tried downloading other email apps but have been unsuccessful. None of the ones I have tried have the "Move to SD" button enabled. Alternately, if an app is minimal in size (< 10 MB) and allows me to store the emails on the SD card, that would also be acceptable.

Here are email apps I have tried so far: GMail (maybe it would work, but since it comes as a system App I can't move to SD), myMail, Aqua Mail, and "Mails" (by Apyfie).

I have a Roundcube server, so I have also tried the Roundcube app, which IS surprisingly app2SD compatible - unfortunately it's broken in almost all other aspects - for instance, I can only see my last 5 emails and no others - so I still can't use it.

I also tried to locate "K-9 mail" but it says it's not compatible with this version of Android.

This phone has Android version 2.3.3.

I am aware that I could probably root the phone and do it that way, but I would prefer not to.

How to duplicate icons
I am using Android 6.0.1 on a Samsung J7.
I have an icon in my home screen that is a shortcut to an app in Parallel Space－Multi Accounts. I want to duplicate it.
(I have created it from within Parallel Space, but it does not allow for creating another such icon.)

How can it be done?

Note that it is not a direct shortcut to an App, so I cannot hit "+" in the folder I want to get the duplicate.
This appears to deal with such case, so it would not be useful.

Remove lock or enable usb debugging on non-rooted phone?
So my little sister locked herself out of her phone which was not rooted, had no recovery software (Cwm, Xrec, etc.) installed on it, and has usb debugging and auto-mount disabled. We don't know the google account associated with the phone. Basically all I have is the phone and a usb cable. Is there a way to get the user data out of it? Adb won't recognise the device btw. I do apologise if it's a stupid question. The phone automatically connected to the wifi, and I'm on Linux, if that helps.

Update: managed to get into recovery but adb only recognises the device in sideload mode.

Verifying a backup which I used ADB via DroidExplorer
I have a non-rooted tablet which I did an ADB backup thru DroidExplorer.  The backup ended abruptly with no success/failure indication (which appears to be a feature of ADB).

I want to verify that the backup looks correct.  I tried using the "upack" on the file folder context menu (which I think was added by DroidExplorer?).  It asked for the password and then did nothing.

I guess there are lower level ways to unpack the file which I'll try next but my questions concerning DroidExplorer are:  Is the context menu "unpack" part of it?  Is it not working or is there a fix for it?  Also, I'd like to backup the external SD card as well...  looking at the backup file size, the backup is only doing the internal mem at most.  Is there a way to include the external SD thru DroidExplorer?  There was a choice for SD\card but I think that might only do the internal one?  And lastly, will ADB work correctly/completely on a non-rooted device?

Wipe Data on Locked Phone Stuck in Boot Loop without Recovery
I am returning a Project Fi Nexus-5X device that went into a boot loop but want to wipe all my data off it before shipping it back to Google Fi.

However:

the device is oem locked

any fastboot erase (fastboot erase userdata, fastboot -w, etc) says I cannot do so until the device is unlocked

fastboot flashing unlock states oem unlock is not allowed

I can't enter recovery mode - doing so from fastboot mode immediately restarts the device, back to the black "Google" screen - and into the boot loop again

I can temporarily enter Download Mode, but the device restarts after about 10 seconds

So I'm not sure of any way to wipe my data at this point.

Sign into wifi network notification not appearing (captive portal, nginx)
I'm using nginx to redirect all traffic to login.com (local server). And I want the sign into this wifi network message to appear. I searched for a long time and found out that android does a request to clients3.google.com/generate_204. If it redirects or returns something else than status code 204 is SHOULD display the login to wifi network message.

But with mine. It doesn't work. Here is my nginx config:

```<code>server {
        listen 80 default_server;
        listen [::]:80 default_server;

        location / {
                return 302 http://login.com;
        }
}
</code>```

When I connect to my wifi network and go to a random website I get redirected to login.com. That works. If I go to a random-website.com/generate_204 it also gets redirected. And yes if I go to clients3.google.com/generate_204 it also gets redirected. But NO 'Sign into wifi network notification' appears.

I also tried not to redirect /generate_204 but instead use alias to display the login.com content but it didn't work.

From https://www.chromium.org/chromium-os/chromiumos-design-docs/network-portal-detection

If for any reason the web page is not returned, or an HTTP response other than 204 is received, then shill marks the service as being in the portal state.

I tried this but it didn't work. (also tried to return code 500 etc.)

What am I doing wrong? It should work because I saw it before.

How to limit an Android app to thousands of specific devices
I want to install a single-purpose app on a thousand of devices of the same model.

The need :

The app shall not be public therefore accessible to anyone

The app shall be installed on my 1.000 devices. Note that the devices are the same model (let's say nexus 10) but I do not want to grant access to all nexus 10 around the world

It shall be as easy as possible. I can imagine for example logging in these 1000 device with a single account and then limiting ditribution to that account, but it's quite long and might as well not be possible (limitation to the number of devices an account can have)

The app shall be updatable on all devices simultaneously

The number of devices might grow to 2.000 or even OVER 9.000

Tried many ways to root my Telenor Infinity E
I have been trying to root my phone for two weeks using various exploits but till now all in vain. The devices isn't international so its not famous and I couldn't find any recovery, custom root or rooting method for it on the internat, although I found stock ROM which saved my phone several times when I soft bricked it.

My Device:

Bootloader: Unlocked

Methods Tried:

Tried famous desktop applications: OneClickRoot, KingRoot, KingoRoot, RootGenius, iRoot etc. (All failed)

Tried flashing TWRP of similar device using SP Flash tool. (Result: Boot Loop)

Tried porting TWRP recovery using stock recovery and Android Kitchen. (Result: Auto reverted back or Soft Bricked)

Tried injecting su, supersu in system.img using android kitchen and flashed. (Result: Soft Bricked)

Tried Many Repack tools like simg2img/make_ext4 binaries, similar tools/guides to repack system.img. (Result: Soft Bricked)

Modified ro.secure=0 and ro.adb.secure=0 in default.prop and re-flashed boot.img (success, but no root)

Used dirtycow exploit scripts got root shell but still no permissions to modify /system.

Patched adbd in boot.img using adb insecure app's assets and got 'adb root' access. (still can't modify /system or remount in rw)

Found SELinux's getenforce=1 and neither could disable it by command setenfore=0 or echo 0 > /sys/fs/selinux/enforce nor found any method except making a custom build of kernel (which is not feasible for me).

Can someone help me to Root this device or tell me if there is anything else I can try?


问:
What vulnerabilities are exploited in the CIA's cyber weapons for Android?
The BBC is reporting that Wikileaks has released information on US CIA cyber weapons, including against Android devices.

A similar unit targets Google's Android which is used to run the majority of the world's smart phones (~85%) including Samsung, HTC and Sony. 1.15 billion Android powered phones were sold last year. "Year Zero" shows that as of 2016 the CIA had 24 "weaponized" Android "zero days" which it has developed itself and obtained from GCHQ, NSA and cyber arms contractors.

These techniques permit the CIA to bypass the encryption of WhatsApp, Signal, Telegram, Wiebo, Confide and Cloackman by hacking the "smart" phones that they run on and collecting audio and message traffic before encryption is applied.

Wikileaks link for Android exploits. Much of this appears to be redacted.

I am not concerned about attacks that require physical access to the Android device. If a nation targets me specifically, I expect them to succeed in compromising my device. I am interested in avoiding being casually swept up
by mass attacks or surveillance.

Assume, if necessary, that we are talking about unrooted, fully-patched Android devices running the latest Android OS (Nougat).

How, if at all, should a normal end-user modify their behavior to maintain their privacy given this disclosure?

Lenovo tablet with two internal partitions - How to move apps to SD?
Not specific to any model but for most Lenovo devices, including phones.

For some reason, some brands, mainly Chinese ones, include two internal partitions. Second partition is shown as "USB Storage" or at least that is what is shown in the "Move to USB Storage" button in App Manager.

It's like a bad joke, because you can buy the larger SD Card the device support but there are no "Move to SD Card" button in App Manager, in it's place you have the "Move to USB Storage" button that does nothing useful because the internal partition detected as "USB Storage" is 1 GB only, sometimes I have seen 2 GB but it still is useless. So you end with a device that you can install at most 5 apps, less if you install Facebook that takes about 300 MB.

Is there a way to get the "Move to SD card" button to show in these devices?

Do they do this to prevent you from moving apps?

Please, do not suggest flashing with alternative ROM. I would do that gladly if the original ROM was around in case of disaster. But as the original ROM of these devices is nowhere to be found then flashing is too risky.

Phone unlocks to settings screen instead of home screen
Since I updated to android 7.0, my phone will unlock to the settings screen instead of my home screen.

If I lock the phone and then immediately unlock it again, it goes back to the same screen it was on. However, if I let the phone sit for 5 minutes or so it will unlock to the settings panel.

I've looked at the "launch when unlocking" threads, which seems to be a dead end since I have not been messing around with programing.

Force inactivity lock on application that circumvents it

However it is NOT fine when I set lock period in phone settings to half a hour, start playing before sleep and WANT it to go into lock if I actually fall asleep while playing! I don't want phone to stay at max heat all night because GPU and charger fight each other over energy flow.  I have an unrooted Lenovo A1000.

Application does not have any setting to disable this behavior. Is there a way I can enforce my lock period settings on any application so any time I don't actively touch any controls on phone for specified time, it goes into a lock, no matter if foreground application wants that or not?

Where should I place iptables update on Android at boot time?
I need to write specific values in the routing system using the iptables command for Android.

```<code>service update_iptables /system/bin/update_iptables.sh
    start update_iptables
</code>```

When I plug the phone to the computer and execute the following sequence, it works without problems:

```<code>adb root
adb remount
adb shell /system/bin/update_iptables.sh

Obviously, when restarting, this configuration is lost. That's why I need to run this as part of the start boot sequence.

Any advice on where in init.rc (or any other configuration file) can I place the script?

Motorola DROID Maxx In Reboot Cycle
My Motorola DROID Maxx, for some unknown reason, is constantly restarting. I tried to put it into safe mode, but to do that it needs to restart and it continues to go through this loop. I had this issue only recently, then I wiped it clean. I put back on my phone the apps I had before (list of them below) and updated some of those that came with it. While I was trying to do that, it wouldn't connect to wifi. I tried to turn it on but it keeps turning off (quite the rebellious). Then it randomly started doing the restarting thing again. I have tried safe mode, but it ignores it. I have tried recovery mode but so far only managed to get into it once. I hit the power button by accident and left the recovery mode.

Later, I managed to get into recovery mode and selected recovery. I managed to get to the menu and rebooted the system. It was no longer in the cycle and was now only shutting down without warning (no vibrations or anything) every time I start it up. At one point, I couldn't start it back up, so I put it on the charger and managed to get it. Then I put it into safe mode and it started the cycle again along with occasionally completely shutting down. After it shuts down it doesn't start up until I start it up.

Any ideas as of why it is doing this? Also, does anyone have a solution?

Here are the apps I have added (to the best that I can remember):

Facebook

Messenger

Google Sheets

Google Docs

Libib (had this before I wiped it, forgot to add it afterwards, so this isn't the issue)

Covenant Eyes (my dad put it on my phone, I don't know if he actually put it on my phone after the wiping, so this may not be the issue)

YouVersion (a Bible App, this is one of the last ones I put on there)

If I put anything else on my phone, I don't remember at the moment. Some basic things were updated (Google apps, camera, gallery, etc.)

Bluetooth keyboard glitches when pressing space
I have a Samsung Galaxy Tab S2, running Marshmallow.  For some reason, when I use my bluetooth keyboard, I get an intermittent error when pressing space (or any punctuation).  As near as I can tell, when it does happen, it is when I press space after a mispelled word (or one which is not in the dictionary) or a number.  When it happens, it moves the cursor to the beginning of the mispelled word.

For example, if I type '2017', then hit space, the cursor will jump to the beginning, like so '|2017'.  As you can imagine, this is incredibly annoying.  When typing my email address, it jumps 3 backwards times.

I know this is incredibly specific, so there might not be an answer.  If I remember correctly, it may have started happening when I added another language to the on screen keyboard, but I've disabled that and the problem remains.

Any suggestions?

Blocking Websites/Apps on Samsung s6 [G920VVRS4CQA3]
After researching all day how to root my specific build number of the Samsung Galaxy s6, a G920VVRS4CQA3, it seems it cannot be done (safely, at least) due to the locked bootloader that comes with the Verizon and AT&T models. I looked into all kinds of different methods but to no avail. (I wanted to root the phone in order to edit the host file and block webpages.)

So, I wanted to ask - what is the best alternative to blocking SPECIFIC apps and SPECIFIC webpages on the android device? I need an app or method that doesn't scream "this app/webpage is blocked due to parental control." I'd like something more discrete that would just lead to a message claiming "server not found" or something of the sort. I am not looking to block ads or filter out an entire category of the internet, I just need a way to block specific websites and apps on the playstore that cannot be easily tampered with. Something with a passcode.

Alternatively, if you have been able to root the G920VVRS4CQA3, I'd greatly appreciate knowing how to went about doing it.

Thanks


问:
Google app "Keep": only show unchecked (unarchived) list items when exporting?
I use Keep for maintaining a reusable shopping list. (Shared with family on other devices). I mark the item with a checkbox when bought for later use.

But if I want to send the list (eg via email) surprisingly it exports all items in the list, both checked (archived) and unchecked! So when I export it, I have to manually delete each of the checked rows from the email before sending. Is there a way around this?

Yu yureka Recovery
I have yu yureka phone on which I tried to unlock the bootloader and flash cwm recovery. As the process continued and at last the window showed ' finished'. I then tried to boot into recovery mode by pressing all hardware keys simultaneously but it didn't opened recovery and the phone started to homescreen. I need to know whether recovery is installed properly or not. I don't want to boot into the recovery mode because last time it did so and the phone was in bootloop so is there any way to know if the recovery is installed properly or not without rebooting it in recovery mode.
Thanks. Please help. </p>

Playing web games that require arrow keys without using a physical keyboard
I would like to play some web games like Unikong using my tablet. But the problem is, they require a keyboard, or specifically, the arrow keys in order to play.

I know I can connect a mouse and/or keyboard via OTG and play, but I don't always have access to them.

I have Hacker's keyboard (has arrow keys) but the game registers my arrow key inputs only sometimes at irregular intervals. This happens not only for Unikong, but other similar games too (I remember creating a small JS canvas game myself that it works fine on the PC, but not with hacker's keyboards' arrow keys). Here is a GIF from where you can see the problem (Sorry for the low quality 5 FPS GIF):

Note that this happens on some games only. For example, this problem does not exist with Chrome's T-Rex game.

So, how do I play web games that require the use of arrow keys using my Android tablet without a physical keyboard?

I'm running a rooted Android KitKat 4.4.2

Why I get the foolowing "Settings isn't responding. ... close it", when i turn Wifi on? (even in Safe Mode!) /Android 501 & Sams S4
Android 5.0.1 /Samsung S4, Not rooted.

Why I get the following message dialog "Settings isn't responding. Do you want to close it?", every time when i turn Wifi on? (even when phone is started in Safe Mode! ...ie without any external app).

In fact EVERYTIME I navigate to Settings and push the wifi to ON itself, it gets stuck there for a minute and the following dialog pops up, with 2 choices: "Wait" and "Close". If closed is pressed then Settings closes and wifi never gets ON. If Wait is pressed then it hangs for another minute and same dialog pops up. Again, if Wait is pressed and after another minute ONLY THEN settings proceeds and turns finally the wifi ON. And proceeds working normally. SOMETIMES: an extra step of dialog appears making the total of appearances at the most 4 times. But even then it finally turns ON and settings is anew functional.

Needless to say while Settings is trying to turn wifi ON, no other function in Settings can be selected and processed...The whole process of Settings is frozen.

I searched internet already and haven't found (tried MANY of proposed) a solution, even though a lot of people experience similar problems with turning wifi on and getting stuck - regardless of type of phone and android version.

It also gets stuck even if i try to ON the wifi directly from the top task bar by pressing the (green) button - it gets stuck in faded green color without turning wifi ON.

Please, has this problem been solved reliably by anyone? All info is much appreciated.

Moto G 2nd Gen Photos disappearing
I am using Moto g 2nd Gen. I have a weird problem with my phone. If I took any photos & leave those  in my phone. After 2-3 months I cant able to view those photos. Gallery shows a Grey image as thumbnail instead. If I touch one of those photos to view, Again grey image. I copied to my Computer to view that no use :(
I even changed my memory card to Sandisk.
Most affected photos are in Phone memory. I lost some of my precious photos.

Why this is happening?

问:
Split Bluetooth Music Playback and Phone capabilities?
I have a car stereo which supports bluetooth phones, but not A2DP audio playback.
I purchased an A2DP adapter.

I have easily paired my HTC Thunderbolt to the Cicada which pipes audio to the aux jack in the Juke, and plays back. (Sounds great, incidentally.)

However, upon connecting to the Cicada, the phone is no longer connected to the Juke for phone calls.

Is there a way to tell Android to force send HSP data to the hands-free set, and force all A2DP data to the A2DP adapter? The A2DP tells android it supports HSP and therefore overrides the Juke pairing.


问:
Is it possible to crack encrypted device?
I have device powered by Qualcomm MSM8974AC Snapdragon 801 cpu and running Cyanogenmod 13 (6.0.1 android) rom with unlocked bootloader and TWRP (3.0) recovery.
ROM has security patch level December 2016. Device is encrypted by FDE (Full-disk encryption) and using same PIN for lock-screen and booting.

Let's say attacker has full psyhical access to this device. The point of attack is decrypt data. Attacker has unlimited tries of entering password:

```<code>devicepolicy/java/com/android/server/devicepolicy/DevicePolicyManagerService.java:

DEF_MAXIMUM_FAILED_PASSWORDS_FOR_WIPE = 0
</code>```

Based on that article if am understanding correctly the only possible way is exploiting TrustZone or Keymaster vulnerability and then just bruteforce psyhical dump on powerful machine.

But thats seems like got patched in January 2016 and May 2016 security bulletin (CVE-2015-6639
CVE-2015-6647 CVE-2016-2431 CVE-2016-2432)

So the question is it still possible without OEM help of course?


问:
Where are the TEE's keys stored and under which conditions are they reset?
Context: full-disk encryption in Android 6.0, specifically key derivation and storage.

I have a device running Android 6.0 with full disk encryption. I need to make a backup of the device, wipe the device, use it in the wiped state for a little bit, then restore from the backup.

I am running a custom recovery (TWRP), but unfortunately it cannot make a nandroid backup of /data because I guess it is very confused by the fact that /data is encrypted.

I was going to make a backup by just running "dd if=/dev/mmcblk0 of=/sdcard/image.img ..." in recovery in order to make a byte-level copy of the entire internal storage, with the intention of later restoring it by doing the same in reverse.

However, I am afraid that the hardware-bound key, which is stored in the TEE and used to encrypt the disk encryption key, is stored outside /dev/mmcblk0 and will be deleted when I perform a wipe. Thus, even though I'll succeed in restoring the image, Android will no longer be able to derive the same encryption key and thus will fail to decrypt my data.

Thus, my questions are:

is this correct?

if so, what are my options? if the key is actually wiped, I understand that it wouldn't make any sense for it to be possible to backup and restore it. However, perhaps there's a more roundabout way to wipe the device of my private information without deleting the TEE key?
