click on switch icon which appears floating on the page

it takes me to the reading list, the I need to click on the article I want to read.

So. Question:
How do I switch a page to reading mode in one click?

How to add/restore the 'Apps' shortcut to the home screen of Apex Launcher
I'm using Apex Launcher. For some reason, I don't seem to have the 'Apps' button on the home screen (i.e. the button on the bottom-right of the default Touchwiz launcher that opens the list of apps).

I've tried to add it manually using QCustomShortcut but I don't know the package name.

Does anyone know how to get this button back or add it manually? Or if someone knows the name of the package or process name (of the 'Apps' process), I may be able to work it out from there.

This is the icon I'm referring to, as it appears in the default Touchwiz launcher: Samsung GS4 home-screen

i9505 Firmware upgrade question
just a quickie:
I just updated (i9505) from XXUEMKE to XXUHOH2
Location Germany - dbt running CM12.1
So far all ok - no problems.
My Question:
After Flash (BL + Modem + WLAN) it´ll still Show XXUEMMKE as Baseband. Using APP "Phone Info": It shows the same XXUEMKE as baseband except under latest Firmware installed  it Shows XXUHOH2 installed.

So, why does the new Firmware not Show under Information - Baseband? What am I missing? And even that Odin said all ok. Is it really installed and running? (maybe I forgot something?)

Very strange: Google keeps on sending 2-step sms
I have 2 phones: an android one, sim-less, that I use only on wifi, and an old Nokia I use everyday (charging it once a week, which is what I need)

How does the android system calculate remaining battery time
I am aware that the Android OS when calculating time left it cannot really calculate true usage, and an A.I. algorithm that would learn how you use your phone and give better estimations would actually deplete the battery on it's own.

On the other hand though.
When giving time left estimations what does it check? Does it check the remaining percentage or the remaining milliamps? Because a phone with 4000 milliamps at 50% will probably have the same battery life left than a phone with 2000 milliamps at 100%

So what does it really check to do the calculations?

How to make URL coming in via Bluetooth open in browser?
When receiving an URL from Nokia phone, my Galaxy 3 shows the URL as text file and I need to first open it via Opera browser, then manually select the whole URL and only then I can open it all (for some reason Opera lacks "Select All"...).

So, what do I need to install to make this go like it goes on Nokia phones, ie. receive URL, tap to open in browser, done?

Opera is not the default handler, but because Android handles incoming link like any text file on file system, the default browser is not offered at all. Picking the other option works even less.

Browse file system from PC in marshmallow
I have a LG Nexus 5 with android marshmallow OS. I used to be able to connect my phone to a PC running Windows 10 with USB cable and browse the files from the PC's file explorer. Ever since I upgraded the OS to marshmallow whenever I connect the phone to PC with USB cable, the PC detects the connected phone but when I open the phone from file explorer there is nothing shown.

After a lot of exploration I found a setting in the notification area called 'USB for charging. Touch for more options'. From there I can choose charging only, MTP, PTP, or MIDI. After selecting MTP I can browse the phone content from PC. This setting used to be in Settings - Storage - USB computer connection.

The problem is the next time the phone is connected to the PC, the setting revert back to 'charging only'.

Can I set the default to MTP like it used to be in lollipop?

How to root Doogee Voyager2 DG310 & other mt6582 Devices (permanently) with EngMode?
Using the Mediatek mt6582 SOC Engineering Mode available on the Doogee Voyager2 DG310, with the Debug option User2Root an adb daemon running as root becomes available temporarily.

This will need USB Debugging enabled in the Android Settings.

To access the Engineering Mode on this MT6582 use the Dialer to call a KeyCode:
(You have to enter another * to launch the Eng-mode)

The Log and Debugging-Tab:

Choose User2Root:

 Click Root:

If you were previously connected with an ADB User Shell, it will by terminated. Opening a new adb shell will get you an adb root prompt.
Until the next reboot.

So far so good. With the (temporary) root prompt available, a generic Android 5.X rooting guide should apply now.

I tried:

Downloading the latest Koush OpenSource SU-package from F-Droid

Extract su from the APK and adb push it to /sdcard/Download/

adb push the APK to /sdcard/Download/

Login as root with adb shell

Remount /system Read-Write

Copy/move su to /system/bin/

chmod 4755 /system/bin/su

chown root:shell /system/bin/su

Remount /system Read-Only

Attempts to run su result in this: error: only position independent executables (PIE) are supported.

Installing the APK before, or after attempting to run su succeeds, but complains about the su binary being out of date.

So, where would I find a newer, clean, "PIE" su binary? Or am I going about this the wrong way, and there is a newer 'Generic 5.X Temp-Root to Perm-Root' Procedure?

Broken Samsung Galaxy S6 Edge won't be replaced
About a month ago I got a Samsung Galaxy S6 Edge bought off from Swiss carrier Sunrise. It's a 32gb model, with European region lock. My brother didn't open it in Switzerland,  and he gave this to me as a gift when he arrived by airplane in Romania.

Anyway as soon as I boot the phone,  I do initial setup. When I connect to a Wi-Fi network it enters a boot loop. The only way to get it back to normal is to hard factory reset it. It happened multiple times,  on different Wi-Fi networks. First I did an software update with mobile data to 5.1.1 Lollipop,  it didn't fix the problem. Then using the smart switch app for PC I downloaded a new original firmware,  guided through live chat by a Samsung official helper,  still didn't fix the boot loop issues.

Then he takes the phone back to Switzerland,  where there was no problem when connected to a Wi-Fi network.  He sends it to warranty for repairs,  they find nothing wrong with it,  after 15 days he gets it back. Just as he was about to send it back to me to Romania,  he does a test and finds out that the phone entered a boot loop for the first time in Switzerland. He left the phone in a boot loop so the guys at the shop could see that the phone was definitely flawed and make sure it's going to be repaired or replaced. After another 15 days,  results came back as if the phone has no problem.

They can't make it enter a boot loop so they have nothing to repair or replace,  however I'm not sure what I can do. I might have just wasted 800$ and the phone is still broken

Any ideas?

GPS is not getting fix signal
I have a couple devices (Moto e XT1021, Moto e 2nd gen). Suddenly the app running on these devices stopped working, due the device stop receiving gps changes updates.

I did some research and tests, and i realize the problem is probably the network provider. For some reason the request made by gpsd process to http://xtra2.gpsonextra.net/xtra2.bin is not getting resolved, as consequence the device takes to much time(more than 15 minutes in some cases) to get GPS fix and not receive updates as expected.

Here is how i did my tests.

Put disconnect wifi, use mobile data only

Put device on Only device, Go to Settings > Location > Mode.

Open any gps status app, check if is receiving gps updates.

The thing here is when the mobile data is connected, the gps status app stop receiving gps updates and satellite signals disappears, So i decided to put the device on airplane mode, then automatically the gps status app start receiving satellite signals and of course gps updates.

This weird thing made me thing the network has something to be here. So i decided to use other sim cards from other networks. And i realize the same configurations is working good, All devices start getting gps updates very fast.

So i went further and made a tcpdump on the device with every sim card, and i realize the the request to http://xtra2.gpsonextra.net/xtra2.bin are not resolved or getting response.

All this story is to know if someone else knows something about or if the network provider can block requests to xtra2.gpsonextra.net.

Is there a way to configure GMail so that it does NOT download large data (especially images/attachments) in old messages in a thread I'm opening, unless I explicitly open the message that contains the image/attachment? I'm fine if that setting is "non-WiFi only" or "100% time".

from command prompt start ADB shell:

switch to root user (your device must be rooted):

go to in target profile directory:

How to get ip address of a router?
Normally when a modem/router is connected to a computer, there are multiple ways to know the ip address of them. I am using an android device and, I have free WiFi in my colony.

The problem is that previously the WiFi connected without any issues and the speed was great too. But recently they changed the WiFi frequency from 5 GHz to 2.4 GHz and now the WiFi doesn't get much signal from my home, and hence doesn't connect. And they refused to change it, and the problem is they never understood it, and it was the work of the repairman who changed it.

I am able to connect to the WiFi and it works, when in range, so is there any way to get the ip address of the router so that I can change the frequency. And also the ISP doesn't even respond to calls, and comes in months if there is any problem. And also I know the password and username, so don't respond to it that I am hacking something.

And when I connect to the WiFi it assigns me 192.168.43.214 address. So please tell me is there any way to know the ip address of the router.

perm=com.facebook.katana.permission.RECEIVE_ADM_MESSAGE pkg=com.facebook.katana]
</code>```

No facebook packages are installed according to the output of

```<code>pm list packages
</code>```

So the problem appears to be caused by stray permissions that have been left behind and are prevent facebook from reinstalling.

Listing the facebook permissions over adb I get the following

```<code>adb shell pm list permissions | grep facebook
permission:com.facebook.katana.permission.CROSS_PROCESS_BROADCAST_MANAGER
permission:com.facebook.permission.prod.FB_APP_COMMUNICATION
permission:com.facebook.receiver.permission.ACCESS
permission:com.facebook.katana.permission.RECEIVE_ADM_MESSAGE
permission:com.facebook.katana.provider.ACCESS
permission:com.facebook.katana.permission.C2D_MESSAGE
permission:com.facebook.permission.debug.SYSTEM_COMMUNICATION
</code>```

Uninstalling using adb doesn't get rid of these permissions
    adb uninstall or adb uninstall -k com.facebook.katana

I don't see the partial facebook 'not installed' entry in settings/apps/downloaded that some users report. My apparently customised settings app doesn't allow access to multi-user features which some people find is related to similar problems.

Can I clean up these permissions with adb? pm revoke won't do it perhaps due to Lollipop limitations. I don't currently have root access and I'm reluctant to root the phone.

```<code>adb shell pm revoke com.facebook.katana com.facebook.katana.permission.RECEIVE_ADM_MESSAGE
Operation not allowed: java.lang.SecurityException: Permission com.facebook.katana.permission.RECEIVE_ADM_MESSAGE is not
 a changeable permission type
</code>```

ADDITIONAL DIAGNOSTIC STEPS:

To eliminate the possibility of an invalid APK I used the Google Play Store app to install the facebook app and at the same time monitored the system using logcat on its most verbose settings. Searching for facebook in the log finds the following error messages which are very similar to the errors from installing the APK directly above:

```<code>    [ 10-26 01:14:26.615   662: 1360 V/ActivityManager ]
Broadcast: Intent { act=com.android.launcher.action.ACTION_PACKAGE_INSTALLING dat=package:com.facebook.katana flg=0x10 pkg=com.google.android.googlequicksearchbox } ordered=false userid=0 callerApp=ProcessRecord{142b6192 2619:com.android.vending/u0a14}

[ 10-26 01:14:43.492   662:  704 W/PackageManager ]
Package com.facebook.katana attempting to redeclare permission com.facebook.katana.permission.RECEIVE_ADM_MESSAGE already owned by com.facebook.katana

[ 10-26 01:14:43.975  2619: 2619 E/Finsky   ]
[1] 2.onReceive: Error -505 while installing com.facebook.katana: INSTALL_FAILED_DUPLICATE_PERMISSION: Package com.facebook.katana attempting to redeclare permission com.facebook.katana.permission.RECEIVE_ADM_MESSAGE already owned by com.facebook.katana

[ 10-26 01:14:43.975  2619: 2619 W/Finsky   ]
[1] 3.installFailed: Install failure of com.facebook.katana: -505 null
</code>```

"permission com.facebook.katana.permission.RECEIVE_ADM_MESSAGE already
  owned by com.facebook.katana".

Does this mean I have some sort of remnant APK from a previous com.facebook.katana installation (facebook was previously installed then uninstalled)? Or does this mean the permissions on the device still contain some reference to a non-existent app com.facebook.katana? Any further steps I can take to diagnose this problem?

EDIT - Blocking apk appears to be partially uninstalled system bloatware facebook app

If attempt to list uninstalled third-party packages, their apk files and installers using adb:

```<code>adb shell pm list packages -f -i -u -3
</code>```

I can see an entry for facebook

```<code>package:/system/vendor/operator/app/facebook/facebook.apk=com.facebook.katana installer=null
</code>```

The only other third party entries in system appear to have been pre-installed bloatware on the phone. twitterappforzte is a good example...

```<code>  package:/system/vendor/operator/app/CleanMaster/CleanMaster.apk=com.cleanmaster.mguard installer=null
  package:/system/vendor/operator/app/twitterappforzte/twitterappforzte.apk=com.twitter.android installer=null
</code>```

Using ADB it's apparent there is an apk file still present here which is presumably blocking the new installation:

```<code>shell@P182A20:/system/vendor/operator/app/facebook $ ls -l
drwxr-xr-x root     shell             2015-03-20 09:30 arm
-rw-r--r-- root     root     26450949 2015-03-20 09:30 facebook.apk
</code>```

facebook is not listed if I filter uninstalled apps by only listing disabled apps.

I've tried pulling this bloatware facebook.apk file from the phone to my local disk and reinstalling using adb but I get installation failures.

```<code>C:\Program Files (x86)\Minimal ADB and Fastboot>adb install facebook.apk
5155 KB/s (26450949 bytes in 5.010s)
        pkg: /data/local/tmp/facebook.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
</code>```

Trying to disable/enable the remnant package using ADB fails with security error, presumably because it's a system app.

```<code>C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell pm disable com.facebook.katana
Error: java.lang.SecurityException: Permission Denial: attempt to change component state from pid=16143, uid=2000, package uid=10098
</code>```

Huge demerits for lousy engineering to ZTE here. Pre-installing facebook and twitter apk files with unknown provenance that can't be updated and prevent updated play store versions from being installed. Great way to put security holes on their phones.

Is there any way to reinstall this system bloatware apk file which is very much still present? If not is it possible to flag this partially 'uninstalled' app as disabled so that it won't interfere with new installations?

Adding uninstalled apps to wishlist in Play store
There is something in the Play store app that bugs me ever since I found out the problem exists: I cannot add previously uninstalled apps to the wishlist.

I made my research and found this thread on XDA where they acknowledge the problem, then this suggestion on Reddit which didn't even get a response and this useless thread on the Google Play help forum. I didn't find any other direct reference to the problem.

I tried to clear cache for the Play Store, but like with the guy that opened the XDA thread, it didn't work. I made sure to delete the app from the 'All apps' on all my devices. The web interface still shows 'Installed', I think this can be related. I think the problem lies in the Play Store, without anything the user can do to overcome the issue.

So my question is: does anybody know of Google acknowledging/addressing the issue in the future? Or, if there exists a workaround?

How can I make my phone stop displaying emoji?
At some point in the recent past, my phone (a Samsung Galaxy S4) started to display several large swaths of Unicode codepoints as emoji characters--including several that are used for other things, like U+2609, the astronomical symbol for the sun, which is now displayed as a little image of a sun.

How can I get rid of these? Everything I find on google is either about how to disable the emoji keyboard, or about how to enable emoji; what I want is a simple, device-wide system to get rid of emoji altogether and replace them with the symbols that the codepoints are meant to represent.

If there isn't any way to do this device-wide, is there at least a way to do it for the Dolphin browser?

Compass only working in GPS status app, not in any other apps
On my Nexus 5 (Android 6.0) the compass is working fine in the well known GPS Status & Toolbox app, but not in any other app like Google Sky Map.

This particular app happens to have a setting for sensor accuracy. When I set it to "Above medium", the compass suddenly works. Unfortunately many of the other apps I'd like to use the compass in don't have such a setting. I have also tried the calibration move a few times, but I don't think that's the problem, because it does work with the right settings.

How do I update my rooted Samsung galaxy s4?
This is a complex question for me so I appreciate anyone helping me through it. I have a galaxy s4 that hasn't been updated since purchase b/c I was afraid to lose root.

I'm in the process of backing everything up now.

My concerns are...

1 Should I unroot? Will I screw up unrooting. I'm not familiar with the latest tools available and I don't know if it's necessary b/c...

2 I assume I can just do a factory reset and that will negate the need to unroot? Am I wrong?

3 Again I assume after doing the factory reset I can do the updates via my device OTA. Here's my most significant concern, that I shouldn't do all the updates b/c the most recent update has somehow thwarted whatever rooting tools might be currently available.

4 reroot, install a current ROM, reset up device.

I've done this a number of times with a number of devices but I haven't done it since I got this galaxy s4 shortly after release. That's how long it's been. I know there are tutorials and videos and tools and forums but I think I have some unique issues and context here. Any help will be appreciated.

Why is my Android phone not receiving text messages from certain contacts?
I'm in the UK.

My phone:

Samsung Galaxy A3 (SM-A300FU)

Android 5.0.2

three.co.uk branded Android & SIM

The symptoms have been detected for these contact situations:

Swiss phone (unknown make/model) in Switzerland

Swiss Android phone in Australia

Norwegian iPhone in the UK

In all these cases the contacts have told me via other channels that they have tried to send me SMSes, and these have not come through. It looks like this has been going on since at least early August. I have been able to receive automated SMSes from a company in Norway in the meantime, and I've not detected problems with UK numbers, so not all numbers are broken.

Today I spoke with Three support, and I was told a very puzzling workaround which actually helped: Delete the contact before sending any more messages! This worked for one contact which tried many times before to send SMSes, but now I'm worried:

Why would my phone stop receiving messages in the first place?

Why on Earth would deleting the contact fix it?

How can I detect if this happens again? I can't keep sending ping messages to all my contacts on a regular basis.

Is there a more reliable messaging application than the built-in Android one?

How to add a text message server to contacts
I work in a rather large company, and I'm a emergency first responder (basically: provide life-saving first-aid, fight small fires and ensure buildings are properly evacuated when necessary). The company alerts us in multiple ways, one being a text message to my mobile phone.

This text message is sent from a server, so there's no phone number associated with it. Instead, the message details say "From: CM Direct" (which I believe is our particular text service provider).

I would like to add a contact for text messages received this way, in order to give it a custom ringtone (something loud and separate from the rest, to indicate this is an emergency call), but within the messaging app I can find no way to do so. For normal text messages I have a menu with an "Add to Contacts" option, but this menu does not appear when viewing a text message from the server.

I'm using an Samsung Galaxy S5 mini with Android 4.4.2 (stock). Rooting is not an option (not allowed because it's a company phone).

Phantom noise diagnosis: logcat included
I've got brand new Moto X Style. Great phone, but I have a weird issue which I'm trying to diagnose.

My phone sometimes makes that volume change acknowledgement noise without any interaction. If you have an AOSP phone, try lowering or raising the media volume using the rocker, the little noise the phone produces to help you judge if the volume is low/high enough; that one.

It does it if the phone's screen is on or off, if the phone is being actively used or sleeping.

This isn't a major issue, but it is a bit annoying. It does it without any pattern I'm able to identify. It even does it when it is on Do Not Disturb/Priority Only. I've captured a logcat which covers few moments before and few moments after this issue occuring, but I'm not really able to make sense of it.

It is not the NFC sound. I know how to recognise that, and it does it when far away from any RFID chips. I've also opened the Notification History panel, and it shows nothing there.

Can anyone help me read it and point towards anything that might give me a bit more of a clue?

Google account and installed apps disappeared after an unexpected restart
I have a Note 3 N9005, Lollipop installed on it. My phone just restarted in my pocket, by my clothes "pressing" power and home button (why does that restarts the phone?).

After it restarted various apps started crashing (contacts storage, settings, internet, android.process.media, Gallery, Key chain) and my installed apps disappeared, so when i want to start them it says app is not installed.

Tried starting Play Store but it insta-closes and does nothing. Neither my other google apps (calendar, keep). So I tried to logout from my Google account, but I can't find it on my list. Account list is empty, and when I tap add account can't find Google.

Here is what I tried:

soft restart

battery remove

clearing Google Play cache

removing Google Play updates

clearing every Google app's cache

What's happening to the phone? I don't want a factory reset, but it seems there's no other way.

(Click image to enlarge)

Update:
two new unsucessful tries:

I rooted the device to try and delete accounts.xml and accounts.db, both came out as a dead end

Wiped cache partition in recovery

Also I tried to factory reset from the Settings menu and I couldn't... safe to say this is hopeless, last try of mine will be factory reset from the recovery menu.

volume down button stuck on android phone
Yesterday i dropped my HTC one M8 pretty badly and it fell straight on it's side. Specifically straight on the volume down button, denting the metal in that area causing the volume down button to be permanently pressed. Now i could deal with not using the volume down button but i ****ed up and restarted the phone. Now every time it restarts it goes into recovery mode. I can boot into safe mode by holding the volume up key on boot. I cant boot the phone normally now. Any advice would be greatly appreciated.</p>

Does a non-owner user profile have rights to wipe an Android phone?
My work is pushing the use of Sophos Mobile Control (SMC) for MDM purposes so we can sync our email to our personal devices. I have a Nexus 5 with Android 6.0 (stock) and my intention is to create a separate non-owner user profile for work. My concern is that if I install Sophos Mobile Control on that profile it will have rights to wipe my phone if lost. It's a nice option if I had control over it but I don't like the idea of anyone else having the ability to do so even for work-security purposes.

Also I found this article regarding permissions required by SMC:
https://www.sophos.com/en-us/support/knowledgebase/116995.aspx

Will those permissions only be available to the profile the app is installed on? Or can it read my SMS messages on my owner non-work profile for example?

Thanks!

My phone keeps changing "wifi" word into "WLAN"
I have a Lenovo A319 with Android 4.4.2 and I have noticed a weird thing.

My phone keeps changing the word "wifi" into "WLAN" whenever it finds it.

If I type "wifi" anywhere on the phone (notepad app, browser, etc...) it will change it to "WLAN". This happens no matter what I wrote it like "wi-fi", "Wifi", "WI-FI" and so on...

I also noticed that it is even changing it in the networking data of installed apps.

Find applications causing a particular advertisement and get rid of latter?
See screenshot:

(Click image to enlarge)

That  ad seems to be the the one causing any application to die abruptly for absolutely nothing.

I saw that ad when I was using Skype. I also saw it when I was playing Clash of Clans and other games.

How do I get rid of it? What applications have that ad?

EDIT:

I restored factory settings and an app tried to ask permission to send ads. I click cancel. After a while that app tried to ask permission again. I have no idea what ad it is.

I did a factory reset. Now the ad is gone. However it is replaced by annoying permission request.

The problem with the permission is it's not clear which app ask for that permission.

Also, I do not think this question is a duplicate because I got the problem even after factory reset and I see that this app is supported by airpush notification. Obviously, as a user, I just want to delete the app. What app?

Furthermore, I can't scan my Android. Every scanner, malware anti virus, airpush detector fails and crashes.

I think some apps are embedded in my ROM. That's why the price is a bit cheaper.

There are a couple of video's that shows this problem.

My device is not rooted and at most of it's factory default settings. There is no custom themes installed and I've tried disabling some of the "bloatware".

I've read some articles about this same problem, and what I can get from it is that the phone is handling to much background-applications. From what I could have seen, people rooted their phones to fix this problem. But I dont want to do this, because this is a new phone.

I couldn't yet believe this is because the specifications of the phone, because they are alot better then my old phone, which didn't had this issue.

How can I fix this problem without having to root or use 3rd-party applications/tools?

Note: This problem is not so bad, but for a > €600 phone, this is kind of annoying.

Apps' (those moved into external SD card) icon vanishes from home screens after every reboot

But after every reboot all the icons of apps on the SD card vanishes from the screens (they are still available in the drawer).

Need help recovering data from corrupted userdata partition (Galaxy S3 International)
Phone: Galaxy S3 International i9300

The phone started bootlooping, and I tried to do a factory reset, but it seems my phone went off during the process.  I'm trying to obtain images etc. off the phone.

I could connect to the phone using adb after some help.  All the other partitions except the USERDATA (/dev/block/mmcblk0p12) mount fine.  Trying to mount this partition gives an error about a bad magic number on the superblock.  I pulled the ext4 partition with adb pull, and none of the other superblocks have a valid magic number: the lower numbers report invalid magic numbers, while for higher numbers I get:

```<code>e2fsck: Attempt to read block from filesystem resulted in short read while trying to open mmcblk0p12.img
Could this be a zero-length partition?
</code>```

I tried regenerating the superblocks, but the subsequent e2fsck could not find the root folder so everything gets hosed that way.

I've also tried using foremost and recoverjpegas per https://help.ubuntu.com/community/DataRecovery , both of which recovered zero files.

However, from what I have read (can not currently find source), I understand that the virtual SD card on the Galaxy S3 is a partition on the
USERDATA partition, so I'm not sure if it may be mountable in a loopback fashion, in which case it's possible these tools will not detect anything even if the data I'm looking for is there.

Questions:

What else can I try to repair/recover the file system?

Is my understanding about a partition within a partition correct, or am I grasping at straws?  (i.e. if foremost/recoverjpeg can't find a .jpeg, should I assume it is gone?)

Why doesn't Note 2(N7100) recognize external hard drive but Honor 6 does?
I have two cell phones Note2 and Honor 6. Both are rooted, and run 4.4.2
Both have a battery of same capacity 3100mAh.
I can connect any of two external hard drives WD passport and WD Elements of 1 TB capacity (both are NTFS formatted and do not have provision for external powering on)  through OTG cable on  Honor 6 and transfer files
But when I connect to  Note2 through same OTG cable,  the  external hard drive LED flickers and can't view the  contents of either drive.

Changing OTG cables,  using multiple apps from play store to manage OTG  mounting did not change anything

I read on some forum that  note 2 battery capacity is not enough to power on the external hard drive for normal operations and is just enough to recognize the  drive,  hence the flickering. This was not substantiated by any technical explanation.  Besides,  Honor 6 also has the same battery capacity!!! So this explanation doesn't sound logical unless am missing something

Would welcome a technical explanation for this please

Edit: situation is the same if the external drive is formatted in FAT32

Phone into boot-loop after flashing custom kernel; unable to mount /data and /sdcard from CWM
My Elephone P8000 was running Eragon 5.5 fine. Then I wanted to flash visi0nary's kernel (_1014), so I used the method described (fastboot flash ...), and when I rebooted the phone, it just kept into boot-looping.

Same phone number with multiple extensions always get registered in the call log with one single user
I'm using the default factory Dialer, Call Log, Contacts app (all those options are running under the same app) on LG L90 running Lollipop 5.0.2.

I created multiple users with the same phone number but then I added a comma (,) and then for each user used a different extension.

For example:

John Doe 1 555 555-5555, 2000

Mary Jane 1 555 555-5555, 2001

Jane Roe 1 555 555-5555, 2002

The problem is that when I receive a call from the office the call always gets registered with the first user that I created with the number. For example, I made a call to Jane Roe but that call got registered as John Doe or I received a call from Mary Jane but the name on display was John Doe. With that I can not know who calls me from the office.

If I try to re-dial that last number it is always John Doe that shows up and then the dialer dials 1 555 555-5555, 2000 instead of 1 555 555-5555, 2001.

If I delete John Doe then Mary Jane (the second user that was created) is the account that get always registered in the call log.

How can I fix that?

Dropping wi-fi calls from one access point to another
I have a long house, and must use two wireless access points to get full coverage. I also have terrible cell coverage so I often use wi-fi calling on my android phone to accommodate. However, when I walk from one side of the house to the other, the call often get muddled or even drops as I pass from what I believe is one zone of coverage into the other. Both of these access point are set for access point behavior only and go back to a home router and then out through our U-verse gigabyte connection. Signal strength throughout the house seems very strong. For home access points or on phones, is there some setting I need to throw to ensure the hand-off between access points happens seamlessly? I know there are some solutions out there that handle this, but I don't have the $$ to buy an enterprise class setup ... any direction is much appreciated.</p>

Add deeplink shortcut to YouTube playlist
My Dad is in a nursing home and I'm trying to make his days a bit more interesting. He's unable to do much more than sit still so operating technology is out of the question. The carers are too busy and generally not interested in technology. So I need a really simple solution to play some Youtube content.

I've put a Nexus7 tablet in the room which is running Lollipop with the stock Google launcher and a Chromecast in the TV. I've removed all icons from the homescreen except the YouTube one so the carers don't accidently get lost. I've created a Youtube playlist that would brighten up his days (old comedy FTW!). However, to get to the playlist the carer needs to tap the user icon and then scroll down to the correct one (possibly too much).

I'd like to make it even simpler so that a deep link to the actual playlist appears on the homescreen.

I'm happy to try anything (custom widget, launcher, 3rd party app etc) but after a lot of searching I haven't been able to find anything that is as simple for the user as I need. Does anyone know how I might be able to achieve this on Lollipop?

WiFi stuck on "Turning on..." after rooting Samsung Galaxy NotePro P900
After rooting my tablet the WiFi stopped working, it activating it just makes it go "turning on..." for a while and then shut down. Tried reflashing stock rom, tried doing a factory reset - Nothing worked.

WiFi worked fine before root so its probably not a hardware issue, unless the root process can physically break the WiFi?

I am certain I used the correct model to flash the root (Using P900 WiFi only)


问:
Change default direction of rotation
I'm using Samsung Galaxy S5 for AT&T with Android 5.0.
When I run a game which runs on landscape mode,
the default rotation is the top of the screen goes left and the bottom is right.
If I rotate the phone, then I can change the direction so that the bottom side of the phone becomes left and top-side to be right.
But I want to set the default so that bottom is left and top is right.
How can I do this?</p>

How to install Android 6.0 If the device is not listed yet?
I am interested in installing Android 6.0 on my device Huawei Honor 7 (PLK-L01).

At this point in time, the device name is not listed in the Android website as a supported device. Would i still be able to install it?

I am really interested to understand the reasons why a certain Android-based device can't support the latest version of Android OS.

Thank you for reading my questions. Any help or explanation would be greatly appreciated.

问:
Google Keyboard Esperanto Dictionary

My goal

To have Google Keyboard predict Esperanto words.

Current Status

As of posting date, I am using the most updated Google Keyboard app, on Android L.

The Esperanto keyboard is present and enabled, but it does not suggest or correct words. There is a personal Esperanto dictionary, but the personal dictionary is empty of words and no Esperanto dictionary is available in the addons menu, even after refreshing.

Possible Resolutions

According to posts on Duolingo in early 2015, Google Keyboard used to support an Esperanto dictionary. It is possible that I have not performed the necessary steps to have this dictionary available on my device. Enabling a Google-supported Esperanto dictionary would be ideal.

If the Esperanto dictionary has been deprecated or is otherwise not available, I would like to be able to add an Esperanto word list to my personal dictionary. However I do not see how to add more than one word at a time.

问:
Why does a contact show up in call log, but not in contact application?
I have a friend with a Sony Xperia Z3 compact experiencing a problem where a contact is accessible from the call log, but not from the contacts application.

Contact does not show up in contacts application.

In the call log, there is an option for view contact, but not for add contact. When viewing the contact, there is a manually added note.

Synchronization of Google Contacts is on.

How do I get the contact to show in the contacts application normally?


问:
Android 6.0: Phone remains unlocked after boot?
I've a screen unlock password set on my Nexus 6P and the password also gets prompted before the device is booted. However, after the device is booted, the phone is unlocked: that is, I'm sent to the launcher.

I regard this as a minor security risk since there's some time after entering the password (before the device is booted) and before the device has been fully booted.

Anyone face something similar? Anyone have a solution?


问:
What is causing my audio playback to slow down?
I frequently play long playlists on my Nexus 9 tablet, while it sits unused in any other way. Since updating to Marshmallow, the audio suddenly slows down to (at a guess) 50% normal speed after 90 to 120 minutes of playback. The audio file needs to be stopped and restarted to restore normal speed.

What I tried:

My first thought was that Marshmallow's new energy conservation system, Doze, was likely to blame. Disabling it for the media player* made no difference, nor did

playing files stored locally or on the LAN or

using a wide variety of other media players.

As this behaviour only started after updating from Lollipop to Marshmallow, I still suspect Doze is somewhere at the root of this. That said, Google produced no obvious mention of anyone else running into this issue and it seems unlikely no one else would have bumped into this.

The tablet is not rooted and both the original Lollipop and the current Marshmallow were auto-updated from Google.

Navmii Map installation problem
I have a Samsung Galaxy Core Prime 8GB, and I tried to install Navmii maps. But, when installing the UK & RROI maps, it has stalled at 91% and consequently failed twice.

I have tried to contact Navmii support, but no good.

Any suggestion?

Cm12.1 Thinks My Apps Storage Is 1Gb Where It Should Be 3Gb
Hello and please bear with me, I did read the insufficient-memory tag and other related posts and couldn't find something that seems to explain my particular problem.

In my device I get "Storage space is running out" which I'm sure is a very common complaint here. But the odd thing about it is that I get very contradicting info when I analyse my storage and everything I tried has failed, so it's starting to drive me catatonic.

The inbuilt storage app says:
Total space: 2.95GB (Available 267 MB).
Apps (app data and media content): 2.51 GB
Cached Data: 42.71 MB

My data analyser app says:
External storage: 16.89 GB free. 6.58GB occupied
Sdcard1: 17.16 GB free. 12.55 GB occupied
System: 382 MB free. 626 MB occupied

So am I correct that phone things my system partition should be 3GB but in reality it is only 1GB? The warning comes at 10% so I am guessing when I reach 300MB I start getting the warning, because some part of my phone thinks that system storage should be 3GB. But in reality the total available space is 1GB, which is very contradicting.

I have 10 apps on internal storage and 100 on SD card. Cache is cleared. No log files, no junk to clean. I have absolutely no space left and I can't see why.

The only explanation is that I have corrupt partitions and that phone is only using 1GB instead of 3GB. (Frankly with 64GB phone, 3GB for apps is a complete joke, so you can imagine 1GB makes the phone completely unusable). Basically I suspect all the numbers are bogus.

I didn't have this issues with CM11 so I am guessing something got messed up while upgrading to CM12.1

I am so fed up with this I will probably soon repartition the phone or switch to unified storage, but before going down that route, I want to see if anyone here understands what on earth is going on here?
