问:
How does an app know, if a screenshot was taken?
How does an android app know, if a screenshot was taken, using the physical buttons on a device? Is it listeniong for the button presses, does the OS give it a signal, etc.?

And can this feature be blocked?


问:
What is a recommended way of viewing SE?
I'm on my Android 13 S23 all day more than the Desktop.

I'm struggling with how to view SE website, using the Mobile or Desktop version. I'm using Samsung Browser since it has zoom and text size. Everything looks ok but I'm in portrait mode and it just looks strange most days. Everything is squished.

I want to get my Android phone as close to the Desktop SE as much as possible so I can enjoy it on such a small screen.

Is the responsive view that SE gives us for smaller screens the recommended way or should I use landscape and be happy and go on with my life?


问:
Is it possible to automatically disabling mobile data when connected to Wi-Fi?
I regularly forget to turn off mobile data after connecting to Wi-Fi. It's not just a waste of battery, it's mainly a problem with random signal fluctuations (especially on public Wi-Fi) where it sometimes disconnects and doesn't automatically reconnect, resulting in me re-using limited mobile data, which I don't want.

Is it possible to turn off mobile data automatically, please?


问:
What is the "MTK Non-Framework LBS" app?
I have a Blackview BV8800 running stock Android 11.  The "MTK Non-Framework LBS" app is non-removable so I assume it's part of the ROM from the manufacturer.  I can't find any information about it.  Is it dangerous? Should I disable it?</p>


问:
How can I keep Android connected to a Raspberry Pi which doesn't provide Internet?
I use a PilotAware aircraft electronic conspicuity device from my Android device. This works fine on my tablet but has recently stopped working so well on phones - it repeatedly connects and disconnects.

PilotAware works like many other Raspberry Pi based devices in offering a WiFi AP but doesn't necessarily provide upstream Internet access. My phone/tablet connects to the AP to enable my SkDemon moving map app to connect a port providing location and traffic information.

This works as planned on my Samsung Galaxy Tab S6 Lite, but no longer works on my Google Pixel 4a 5G (Android 13) or my friend's Pixel 2 (Android 11). It used to work in the past. It simply won't stay connected to the AP being as there is no Internet connection:

My new Samsung Galaxy A54 seems to fare better as it asks what to do, but I have seen a similar dialog in the past on other devices.

Things I've tried, that don't fix it:

Disabled Battery > Adaptive preferences > Adaptive charging and Adaptive battery

Disabled Network & Internet > Adaptive connectivity

Disabled Mobile data (not really a fix, but worth trying)

Set a static IP

There must be more use cases where a non-Internet connected AP needs to be accessible from Android.

Galaxy XCover 6 Pro not connecting to computer via USB
I am currently having difficulties in connecting my Galaxy XCover 6 Pro to a computer.  When I plug it in, it charges for about 1-2 seconds, and then the charging stops.  The computer never registers a device being plugged in, and I do not get the prompt on the phone to switch from charging mode to file transfer mode.  I have tried multiple different cables, multiple different USB ports, and both Windows 10 and Windows 7 computers, and there is no difference in the experience.  The phone does charge fine, so long as the charging cable is plugged into a USB wall charger. The phone is running Android version 13.  Is this an issue other folks are having?  Searching for help on the internet does not show any similar problems for other folks, nor any applicable solutions.</p>

问:
How do I restrict access to a Git folder on Android to only certain apps without a password check?
I want to secure a git folder on an Android device so that only specific apps do have access to its content of it. In the best case, there shouldn't even be a password check. I have sensitive data which should be easily accessible between my devices. Using git is the best option in my case, so switching to another option is not wished.

On my Huawei Nova 5T (non-rooted), there is no integrated option to encrypt the data or anything similar. I tried to use Shelter, but that seems not to do the job. Using X-plore file manager I've got a vault to store files, but I can't see the location on my phone so I couldn't use it for git + being asked for a key isn't as comfortable as I like to have it.


问:
How to handle touch event when touching fingerprint sensor on Android?
I want an app that when I touch the fingerprint sensor, it can do special things like go back or home. I do not need an authentication of any fingerprint, only responds to touch events. Are there any callbacks to invoke, or do I need root or Xposed?

The issue is that the sensor goes to sleep after unlocking the phone and it is not listening to any taps or gestures.

问:
How to copy screen lock password from one device to another in Android11?
So I'm trying on copying the Android 11 screen lock password to another same device
our customer does not want to set the password one by one

and I find out a resolution:  copying files

However it only works in the scenario if the device password is not been set.

while copying the file below to the device without a password  after rebooting the device the screen lock will show up and the password is as expected**

Unfortunately, it will not work if the device's password has been set; the screen lock will still show up but the password was not as expected

What did I miss here? Does anyone know?

the code below what I am trying to do  is to copy

1.locksettings.db

an SQLite database containing the lock screen settings

2.copy /data/system_de/0/spblob/*

In order to unlock a real user, you need to know a synthetic password. However it's encrypted by the Keystore, so you need the real password to unlock the Keystore first

for example

.00000000000.handle: return value of gatekeeper first enroll by synthetic password derived password

handle.pwd: the second gatekeeper enroll by real password with a fake user ID (e.g. user_id + 10000).

handle.secdis: Actually a random number. Used to encrypt the synthetic password.

handle.spblob: encrypted synthetic password

3.
copy /data/misc/keystore/user_0/

keystore key. Used for encrypting synthetic passwords.

```<code>cp -rf /storage/self/primary/export/configuration/Settings/lock* /data/system/

chown system:system /data/system/locksettings.db
chmod 660 /data/system/locksettings.db

rm -rf /data/system_de/0/spblob
mkdir /data/system_de/0/spblob/
chown system:system /data/system_de/0/spblob
rm -rf /data/misc/keystore/user_0
mkdir /data/misc/keystore/user_0/
chown keystore:keystore /data/misc/keystore/user_0

cp -rf /storage/self/primary/export/configuration/data/spblob/* /data/system_de/0/spblob/

chown system:system /data/system_de/0/spblob/*
chmod 600 /data/system_de/0/spblob/*

cp -rf /storage/self/primary/export/configuration/data/keystore/* /data/misc/keystore/user_0/

chown keystore:keystore /data/misc/keystore/user_0/*
chmod 600 /data/misc/keystore/user_0/*
</code>```

For additional question:

Yes those command above need to run under root acces ,however because it is a customize os so we make those command run under a system service and fix some sepolicy avc error so the customer do not have root acces for sure and we can run those command even under an unroot device


问:
Screens wakes up right after timeout for no apparent reason
There's a strange situation on my new phone where as soon as the screen turns off due to inactivity, it wakes up again by itself after a couple of seconds. (However, if I turn it off manually, it stays off.)

I noticed that this stops when I disable "Wake screen for notifications". However, there are no notifications coming in when this happens or even an active notification that can be dismissed but hasn't; the display just wakes up at a very regular, short interval after it goes to sleep.

Other similar problems I found mentioned on the Web don't seem relevant; e.g.,

it happens even if the device is not moving (but "Lift to check phone" is off just in case).

"Screen attention" is off

Question:
I would like to stop this from happening but still have the display wake up when an actual notification comes in. Any ideas / previous experience? If not, is there a way to find out exactly what's causing it to wake up?

Device details:

Pixel 6 Pro

Lineage 20-20230331-NIGHTLY-raven (Android 13)

UPDATE

Not sure  if this is helpful or relevant, but here's the output of logcat around the relevant time, filtered for "DisplayPowerController" entries: https://pastebin.com/QKLXutxC

Android-x86 Instagram doesn't show front/text in Instagram app
I am running Android-x86 and I want to run Instagram on it. New APK versions only run with this blurry front:

I have tried a lot to fix it, well to the best of my ability. I installed old APKs and Instagram looks normal. But I can't log in because the APKs are outdated.

Can anyone please help me to fix this? What do I have to do? Is it even possible to fix it? Is anyone successfully running Instagram (not the lite version) inside Android-x86?


问:
Block calls for many time ranges in the 24 hours
I have Xiaomi Poco F3 running on Android 13, fully updated. I know my relative is aging fast in the last few months, so we normally call each other 4 to 7 times a day. TODAY: I visited her at 11:20. At 14:05, she had already called me three times. So, to put down a little stress on me, meanwhile letting her keep her phone, I thought about taking a selective blocking action on that number.

Says my phone refuses her calls:

from 00:00 to 08:30

from 09:45 to 12:30

from 13:30 to 16:30

from 17:10 to 18:45

from 23:00 to 00:00

While I may call her anytime, she will be able to reach me only on the usual timetable:

Coffee time 08:30 > 09:45

Meal time 16:30 > 17:00

Supper time 18:45 > 23:00

BUT NOT DURING WORKING HOURS AND NIGHT. Meanwhile, all the other calls are as per usual

I couldn't find any leads to a practical answer on the web. Only generic-non-useful-well-known.


问:
redirect clients of your android hotspot to custom web page or send them a link notification
redirect clients of let's say my android hotspot to custom web page or send them a link notification without rooting if it is possible. The thing i want to accomplish is to be able to send a link the moment someone connects to my mobile wifi hotspot with no password and to get redirected to a url or get a notification.

The concept is to be able to send notification to multiple people cellphone to cellphones and only the sender is necessary to have the app. Can that be without rooting the phone?

Porting Bluetooth dongle CSR to Android TV box
I have an Amlogic S905 TV box with no Bluetooth, only WiFi. I started porting the external Bluetooth adapter (CSR 4.0) driver to this box.

I found that the box kernel has inbuilt support for Bluetooth. I checked this using dmesg | grep -i bluetooth and it shows Bluetooth core ver 2.18

Screenshot of terminal output

but there is no physical hardware present.
Also, there is a lack of required files like:

/system/app/bluetooth.apk,

/system/lib/hw/bluetooth.default.so,

/system/etc/bluetooth

Then I successfully compiled btusb.ko driver in Linux by downloading kernel source code and pasting in /system/lib, and driver btusb.ko is successfully installed now. The dongle detected in dmesg log as

```<code>#rfkill list
0: hci0: bluetooth
Soft blocked: no
Hard blocked: no
</code>```

But I am unable to use it because Bluetooth functionality is not on.
I need help with how I paste the required files in the system folder to turn it on.


问:
SwiftKey 3 randomly quits giving suggestions?
I just downloaded the new version of SwiftKey (3) on my HTC EVO running Cyanogenmod 7.1 (supersonic). I use GOSms for texting, and it gives me a popup whenever I receive a text, so I do not have to venture all the way to the messaging app. However, the word suggestions and autocorrect function (as are basically the point of using SwiftKey) do not function in the popup window, and only work after I go back to GOSms to reply there.

Occasionally and seemingly randomly, SwiftKey will not provide suggestions and autocorrect will not function. This usually requires exiting out of whatever is using the keyboard and re-entering that application.

Has anyone else experienced this or found a fix?

How to play sounds at set times per day, like an alarm, but only once per time and with no need to interact?
I have tried Alarm Clock Xtreme which alleges to do this (play alarm, and dismiss automatically after 1s, which is the length of the sound) but it doesn't actually dismiss and just keeps looping. What other options do I have?

Use case: play one.m4a at 01:00, three.m4a at 03:00, etc. to twentythree.m4a at 23:00, every day. Each file is one second long and should be played exactly once, and preferably with no popups.

I recall I saw a place where all apps were listed and a checkbox was next to those apps that supported moving to SD card, so I could [X] check all boxes and tap one big Move button to move all those apps at once instead of guessing one by one which one can be moved. How do I do that?

After Googling around a lot,  I found this page, but I cannot find the menu it talks about and cannot find any Multi-select option. I also cannot find the Settings app they mention. In addition, their method seems to require the phone to be rooted. How can I do the same -- multi-select the apps and move them to the SD card all at once? (what would also help is a list of all apps on my phone that support moving to an SD card)

PlayStore does not update APKMirror apps
I have an Android device where I have not assigned any Google account to it, just because I don't like/trust Google.

Since I cannot use the PlayStore to get apps without assigning an account (thanks for that Google...), I have downloaded some APKs from APKMirror.

Now, I see that the pre-installed Google apps get updated by the PlayStore, but the ones I have installed manually, after downloading them from APKMirror, don't. Despite the fact that I have read somewhere that this should work and that apps should be updating.

Is this some new Google way of forcing things down our throats?

Am I missing something?

Android in system recovery mode gives an error on Windows
I have an old phone and I want to see if I can use adb in recovery mode on the device to mess around with the system, but when plugging the phone in after booting into recovery mode Windows immediately gives an error "the last usb device you connected to this computer malfunctioned and windows does not recognize it". I tried unplugging, plugging back in, the cable is fine, the phone works when booted normally and adb works fine and the computer recognises it. It just doesn't work in recovery mode.

It may be an issue with the usb driver in the recovery image but I don't know enough about Android so I have no good idea. I'm not sure if they shipped a phone that can't connect in recovery mode from the factory, but that would be weird. I like the stock recovery since it lets you backup and restore the /data partition to sd card.

I noticed when plugging it into a different port it sometimes shows up in device manager with an exclamation mark. For some reason it sometimes gets recognised but it automatically uses the driver "unknown usb device (device descriptor request failed)" so I assume there is some missing recovery mode driver for Windows. What driver am I supposed to use and where do I find it? I think it's a MediaTek made custom bootloader but I'm not sure.

I can't boot into fastboot mode, choosing fastboot on startup just freezes the phone forever until I pull out the battery or let the battery drain for hours. I can't remember fastboot ever working and I would also like to get that working like it should.

  “SD card is damaged - You may have to reformat.” How do I fix this problem?

I have a Sprint Kyocera Echo.

I accidentally pulled out the micro-sdhc card when in use. When I put the card back into my smartphone, it said "Damaged SD card, you may need to reformat it". When I pulled down the notification bar, it gave me the option to format my SD card, with a warning also of losing all my data. I formatted it and it said "erasing sd card", finally, a message "SD card is currently being checked" appeared.

When I placed the micro-sd card into a SD card adapter and put it in the digital camera, nothing seemed wrong. My camera took pictures like normal and made no complaints about insufficient memory. The logic is in to see, how the camera would react.

I put the SD card adapter into my computer and it read normally. My computer fully recognized my micro-sd and the files, along with the pictures I had just taken on my digital camera.

I took it out and placed it back into my phone, yet my phone still popped up with "Damaged sd card" message. I put the card back into my computer and formatted it through the PC, saying it successfully reformatted my card. I think its fixed or so I thought.

But no, still "Damaged SD card" error message on my phone.

Android Ice Cream Sandwich Performance on HTC Vision / Desire Z
I've got a HTC Vision / Desire Z (aka. T-Mobile G2), and I flashed a custom Android Ice Cream Sandwich (ICS) 4.0 ROM on it. Unfortunately, performance leaves a lot to be desired.

I've tried the following so far:

Overclocking to 1.8Ghz (device locked up, so I reverted to the safer 1.4Ghz)

Limiting background processes to 2 (under Developer Options)

I'm wondering what the impact of enabling "Don't keep activities: Destroy every activity as soon as the user leaves it" is. Would that be a good thing, or would it hurt performance? Are there any other options I should consider for optimizing ICS performance on the G2?

Motorola Triumph & HyperShell in Titanium Backup
It would seem that Titanium Backup, everyone's favorite root backup tool (right?), does not particularly like the Motorola Triumph—or vice versa. I've been having problems with restoring apps (only the Manual, APK installer method works) and integrating system updates (it just hangs, and then the app it hung on is broken until I restore it from a backup).

My TiBU (5.4.0.2) main screen says that I have root, BusyBox 1.20.2-Stericson from system, and HyperShell—but then turns around and says "Fast/Auto app install: NO (HyperShell needed)". Whiskey Tango Foxtrot.

The BusyBox I have installed is the latest version, and I had the same problem when I was using the BusyBox 1.18.x build included in TiBU. I have also tested using both the stock and Umph v1.0 kernels.

Force widgetlocker theme's default image?
I'm trying to get WidgetLocker to work with an "Xperia ICS" theme. So far the theme looks good but I have a bit of issue about the right slider.

As you can see above, the right Camera slider looks just fine. However, instead of launching the Camera app, I want it to instead run a Tasker task that captures images instantly. I have the task already setup and its working fine.

But when I select it to be the action for the right slider, it obviously uses the icon I set to it by default.

So I went and extracted the right slider image from the theme zip file in an attempt to restore the slider back to how it looked like on the first image. However, when I selected the right slider image, it doesn't fit nicely and thus makes it look smaller than the left slider.

And so my question is, how do I make it look like how it was on the first image while opening a Tasker task instead of launching the Camera app?

A more comprehensive list of Voice Actions keywords?
The formal Voice Actions web page lists a small number of Voice Actions keywords:

send text to

navigate to

call

map of

note to self

listen to

send email to

go to

{anything else} fires Google Search?

But when I use certain applications which use Android's built-in speech recognition, the recognizer won't respond to certain other keywords as well. Instead, it will wait until a second word will be spoken before acknowledging "end of speech" and returning with a result (often the wrong one, because it's always the 1st word plus the 2nd word).

The fact that the returned result always includes the 1st word tells me that Google's recognizer heard it, but decided to ignore it for some reason. So the only explanation I can think of for now is that these must be "reserved keywords".

For example, two common such keywords I found to be exhibiting this behavior are: open and exit .

Have you experienced this too?

If so, with which words?

Update: I just observed that some phones are more prone to this problem than others. What does this mean?

But I would like to have some berif statistics about good apps/most downloaded apps in google play.

I can see lot of third party blogs - sorting n rating apps and prearing TOP 10, TOP 50 kind of list. but I can see its not official or proven.

Ringtones and alarms changes randomly
3 weeks ago my HTC EVO 3d (rooted, S-OFF and with LEEDroid latest ROM) started to randomly change ringtones and alarm tones (mainly at reboot, but occasionally during normal use).

If I restore the right tones settings then the right tones are played, until I reboot the phone. When the phone restarts (and sometimes also without rebooting) tones changes again.

New tones are random, but the pool is limited to a very small subset of the tones I have availables (the tones I use more often) Some of them are on internal memory and some of them are on SD.

Moreover, another problem appeared at once: the alert tone for received mail in the mail app (NOT gmail) should be the one set in the "message" setting (in Mail there's no place to set a separate tone) but on my phone it is not... it's another tone that I never set anywhere.

Already tried to fix permissions, check for SD errors, but no result.

There's something I can check to see what is failing in the system? I can use adb and all the development tools if needed.

Wi-Fi issues with HTC Desire S
I have an HTC Desire S, which I have had no issues with until now.  It is now not recognising any Wi-Fi networks. When I switch on Wi-Fi it scans, then gives me a green tick telling me it has it but it does not actually bring up any network. I have tried this in various locations so I know it is not an issue with my home router. I have also installed a Wi-Fi management app, and when that did not work I did a full factory reset.

Any help would be gratefully received as I am pulling my hair out now.

In the / directory of an android device is a file called config what is this file used for?

When I look in the file (on rooted device), it is empty!

Are the files hidden? Or is there nothing there? thanks


问:
Set up an automated SMS server with Android (and a computer)?
I'm looking for a way to set up an SMS server (I don't know if there is better terminology for this, but probably).

What I want:

use the phone as an SMS gateway for an automated server

let the phone send and receive messages

use a computer to command the phone what to do

Specific example use case: The phone gets an SMS message [family] The party today will start at 2pm. Which the computer will interpret and will order the phone to send the message over to all the numbers the computer has in the family list. Or f.e. [add]family,0123456789 to let it add numbers to lists.

So what do I exactly need?

An app that can send all it's incoming messages to an HTTP server and can receive orders from that same server. Of course USB would be a better method than HTTP because it's safer.

Huawei IME and input language
I've encountered a problem using my Huawei U8350 Boulder powered by Android 2.2.2. The phone has physical keyboard and I would like to switch between different keyboard layouts (or input languages) while browsing. I have two input methods one is Huawei IME and Android keyboard. I checked forums and they suggests to find "Input languages" in "Android Keyboard" settings which is unavailable on my phone.

However Huawei IME is very handy and has a hotkey to switch between input languages, but it looks like it works for Chinese only, because when I switch it to, for example, Russian it still uses English letters.

Maybe someone encountered such problem and knows the answer?

Using GPS status the GPS itself seems to operate fine.

Repeating Outlook calendar appointment on Android 2.3 calendar
I synchronize my Outlook 2010 calendar via an Microsoft Exchange ActiveSync account with my Samsung Galaxy SII (Android 2.3.5).

It works pretty good, except for appointments with repetition. I created a monthly appointment in Outlook with invited participants and then I see it as several sequential appointments per month on the Android calendar (e.g., I set last working day of each month in Outlook and instead of 8/31 only, it results in 5 appointments from 8/27 to 8/31 on the Android.

Some features of Chrome for Android cause it to crash to the homescreen
I have an LG Optimus 2X P990, which is running Android 4.0.4, ParanoidAndroid ROM. I have downloaded Chrome for Android from the Google Play Store and it works like a charm in some places, but others just dont work.

For example, one of the most important features to me is tabs. Once I click the tabs button, it doesn't cause any errors or exceptions, all it does is close Chrome. The same thing happens with some other features like gestures and such - it just brings me back to my homescreen.

I have tried this on several ROMs, but none work. Is there a fix for this? Is it a known issue? How can I fix it, or is it something with my phone's hardware that simply will never work?

Reboot

Mods are modifications to the ROM code.  For example, replacing the Power Off menu with one that includes the option to reboot instead of just shut down.

How to set android as internet gateway for my home network
Title should say all, but here's some network topology:

So I'd walk into the reach of my wifi and my android would connect to the wlan automatically and voila, internet for the rest of the network.

I think this is a good approach https://help.ubuntu.com/community/Internet/ConnectionSharing and I'll probably figure the rest out myself before long, but if someone who knows what they are talking about could create a better guide or even an app for android for this, it would be much appreciated.

As for the use of this. e.g. range, network resilience (when used in mesh networking).

Is it possible to use another name for e-mail addresses of a specific contact? E.g. I prefer my phone contacts to have their names in greek, but when I send them e-mails I would like to have their names in english in case a foreign recipient is also included in the e-mail.</p>

How can I install an app if I have inconsistent UIDs and the market app crashes?
I am having issues with inconsistent UIDs. Trying to understand what was going on, I got the advice to install a terminal emulator.

The problem is that when I go to the Market app, I receive a (very fast) error message, which says that the process com.android.vending is not working.

How can I then install one of the apps that have been suggested to me?

University network crashes phone
At my college the Wi-Fi uses WPA2 Enterprise to secure the connection. I log in with a username and password. My phone (LG Optimus Elite, Android 2.3.7) successfully connects to the network, and I can use it for an arbitrary amount of time before the phone suddenly crashes and reboots. I've successfully used the phone on other wireless networks, so i know that's not the problem.

Any ideas?

The specific configuration of the network is below (per the university's directions)

```<code>EAP method: PEAP
Phase 2 Authentication: MSCHAPV2
CA Certificate: unspecified
User certificate: unspecified
Identity: MyUserName
Anonymous Identity: Blank
Password: MyPassword
</code>```

Edit: Common times when phone crashes (only on university Wi-Fi, never any other time)

Loading/Panning in Maps

During unlock

Loading a webpage

...randomly when I'm not doing anything

问:
ADB Shell command that can test MLS / SPC codes?
I am a Republic Wireless subscriber with the Motorola Defy XT. The Defy is a decent phone, but unfortunately very little space has been dedicated to internal application storage (300MB) and often we are running out of space so we are on a quest to get root access to alleviate our issues. Sadly, RW has not provided us with the MLS / SPC code to modify the device.

My question is, is there an Android shell command that I can issue that will directly / indirectly test the validity of an MLS / SPC code. In other words, a command that changes a setting that requires the MLS code to be passed along as a parameter.

My hope is that I can write a script that will test all possible combinations of the six digit integer.

Samsung Galaxy S stuck in boot loop when 100% charged
Before we start I should mention that I have not messed with the firmware in any way. But it seems that whenever I put it on charge and it reaches 100% capacity I turn it on and it gets stuck in a boot loop. I have turned it off and on while it hasn't been on charge and it worked fine.

This happened once and I wiped all user data from the phone and it fixed it. But it's doing it again and I have tried looking around on Google but I cannot find a solution at all.


问:
Android and Windows 7 Homegroup
I have an Android tablet and my PC running Windows 7 Pro. I am using ES File Explorer on Android to see shared folders.

I added some folders to the Music/Picture/Video libraries and shared them in a homegroup. I tried to make the homegroup not need a password and it'll let me access my PC from my tablet and view the root folders but as soon as I tried to access a folder (Music) it'll say permissions aren't available. It will work if I set a password and login with my account.

The second issue is that I'm seeing folders that I don't want to see. I can see a ADMIN$ folder (which is C:\WINDOWS), C$, D$, E$ (the HDDs), IPC$, print$, User. As well as Music, Pictures, Videos from the library. The folders in bold aren't shared so I don't know why I'm seeing them.

The last issue is that a folder (a whole drive actually) isn't being shared. I included the whole E: Drive in the Videos folder but it won't show up in the Video folder from the tablet. However if I include a folder from within the E: Drive then it will show up. Can I not include the root of a drive in a library? I mean it works on the PC.

CM 7.2 Default Calendar View & Back Button Behavior
I have two Incredibles, both with CM7.2.

On one, with the calendar open and in Agenda view, if I press the back button, the calendar exits.  If I re-enter the calendar, it correctly goes back to Agenda view.

On the other, with the calendar open and in Agenda view, if I press the back button, the calendar goes to monthly view, and I have to press back again to exit.  If I re-enter the calendar, it incorrectly opens in month view.

How can I set default calendar view to be Agenda?

How can I get the back button to exit the calendar instead of changing the view?

Tagging photos when importing them from my Galaxy Note
I tried to import the photos I have in my Galaxy Note. While importing them the computer asked if I would add a tag to them -- and I did.

Does this mean that my photos will appear to whoever chooses the same tag?

Why is Caller ID not working since 4.0.4 update on Droid 4?
I have a Samsung Droid 4. I keep all information about my contacts in Google Voice. In the past, this has always worked seamlessly.

However, since my phone updated it's operating system to version 4.0.4 last week, caller ID is no longer working. When people call me now, their telephone number shows up on the phone's screen. However, it doesn't match that phone number to their name from my contact list.

Is anyone else experiencing this problem? What is the fix? Why did this happen?

问:
Setup Exchange OWA / Activesync on Android or iPhone
I'm wondering whether there's a way I can configure my phone sync my corporate emails and calendars?

Sometimes when I'm away for meetings all day, I am not informed of any last minute meeting changes, or I could have forgotten about certain meetings during the day. It can get quite challenging and embarrassing managing such situations especially during days when I'm very mobile. I'm sure my boss isn't too happy about it.

The challenge is, my company has disabled the activesync feature on our corporate Exchange server.

The only solution I have now is to access OWA via my phone periodically to check my email. However, I can't possibly do that all the time. I found out also that there are phone apps that could do this, but I would need to pay for them. And in time to come, my company is going to disable OWA altogether, and that would render my small investment in the app worthless.

This makes me wonder whether is it really so complicated to configure one's phone to perform something so simple?

Since I could configure my personal laptop to download my corporate emails, there must be a workaround to still sync my phone to the Exchange server. However, there's no feature for me to configure certain settings on my phone which I could on my Outlook. For instance, "Exchange Proxy Settings" and "Only connect to proxy servers that have this principal name in their certificate". Does anyone know if there a way to force your phone to allow the same Outlook configurations?

Otherwise, is it possible to perform activesync natively via OWA instead?

If all else fails, I guess I could only either throw in the towel and find some other non-geeky ways to resolve this problem.
