Cannot tether to Windows phone - SSID shows an asterisk
I have a Neuropad 2 running Android 4 ICS, and it is generally OK when using WiFi.

I want to tether it to my HP phone running Windows 6, which means I have to use the WMWiFiRouter app. Unfortunately, this app only offers WEP encryption, which doesn't bother me from a security standpoint.

The tablet picks up the SSID, and registers it when given the password, but will not connect to it. Instead, in the WiFi settings, it says "saved, secured with WEP", and when given the command to connect, does nothing.

What I find odd is that in the pad's WiFi settings, my own routers are simply identified with their SSIDs, but the one for the phone has an asterisk in parentheses immediately before it i.e. (*)HP_Phone - saved, secured with WEP

I do not know what this indicates, or why it is refusing to connect.
Any enlightenment would be appreciated.

Can I flash another modem firmware from a CWM recovery (and not touch the main installed OS otherwise)?
On a Samsung Galaxy S, I followed the complete instructions for installing CyanogenMod 10, and now I have CM10 as the main system, and a ClockWorkMod-based recovery system (from Replicant), which is bootable by holding VolUp and VolDown when powering up the device. (BTW, CM10 allows to choose to reboot into recovery through the usual PowerOff menu.)

If I store .zip with another modem firmware (a radio image from the list at http://forum.xda-developers.com/showthread.php?t=1158783) on /sdcard/, can I flash it from the recovery mode (so that the main system will be not touched otherwise and will work as before)?

(The .zip content looks like this:

Galaxy S2 is possibly bricked. What can I do?
Background:

Browsing on Chrome, device suddenly freezes. Hold down power button to turn it off.

Turn it on again. "Galaxy S2 i9100T" logo keeps displaying nothing else happens. Tried rebooting again, same result.

Try to do a factory reset through recovery mode. I notice that the progress bar freezes unlike the resets I've done before. Takes a while. I get a bunch of errors in red with failed to mount on E/ and invalid arguments (this is the best I can recall).

Now when I turn it on the Galaxy S2 logo will blink in 3 second intervals.

Tried using Odin to root it and install fresh firmware (followed this guide). I also used  Siyah v5.0.1.tar as directed. Using latest version of Odin.

After clicking start (auto reboot, f. reset time and PDA checked) Odin gets up to NandWrite. A couple of minutes later I get an error message that it failed.

After unplugging my phone will show phone...orange "!"...PC. I can't get into recovery. When I go into Odin mode it detects a custom binary.

I'm afraid that my phone is bricked at this point and I don't want to get myself into further trouble without consulting someone who actually knows there way around these things.

What are my options here?

(I would prefer to keep the stuff on my sD card but if it has to be deleted as a last resort then so be it.)

Need to unlock Coby tablet; MicroSD card not formatted
My Coby Kyros MID7024 tablet is locked with a pattern lock. The person who set the pattern lock has unfortunately forgotten it. I tried to unlock the tablet using these methods:

The volume adjustment buttons are broken, so it is no use to use them to reset my tablet.

When activated, the reset hole does not remove this pattern lock. Why?

I plugged my tablet to my laptop (before its USB ports broke) and tried to unlock the tablet with ADB (which can be found in the Android runtime and developer tools from Google). Unfortunately, I forgot to enable USB debugging just in case it ever got locked up.

My MicroSD card is not formatted right now, so I cannot download an app to unlock my tablet because I need to format the SD card before I put anything on it again.

I do not know of any other methods to unlock the tablet.

Maps location out by 12,742km - the other side of the world
OK, I am mystified.

We used to live in the UK. Two plus years ago we moved to New Zealand. My wife has just bought a brand new samsung galaxy note 10.1 (running 4.0). I have installed 4.2 on my eeePC.

When we run "Maps" BOTH devices show our location as our old house in the UK from
two plus years ago.

The galaxy note has a built in GPS. Location services are turned on. A GPS status and indeed other free apps show the correct location in New Zealand.

My eeePC does not have a GPS. We both created new gmail accounts for these devices.

Surely the built-in GPS should have priority over any guessed position nonsense.

My questions:

1) Where is it getting the old position from?
2) How can we fix the Galaxy Note 10.1? (my wife is not very happy)

Bluetooth Keyboard won't automatically connect
I have a Logitech k810 Bluetooth keyboard, which can switch between 3 devices with corresponding buttons. I have it paired with my Windows 7 laptop, a Tablet, and an HTC Rezound with Andorid 4.0.3.

I can switch between Windows and my Android tablet with no issue. I just press the corresponding button on the keyboard and 2 seconds later I can type on either device.

When trying to switch to my phone, the keyboard LED blinks as it attempts to connect but never does. There is no indication on the phone. The keyboard's Bluetooth profile on the phone is activated (checkbox is checked). If I select the device in the Bluetooth device list, it says "Please press any key on your keyboard to reconnect.", but pressing keys does nothing.

It appears the only way to actually connect it is to press the conncect button on the keyboard and manually go to the phone's Bluetooth device profile options and click on the already checked checkbox for the keyboard input.

I imagine this would happen with my phone and any Bluetooth keyboard, which ruins the convenience of a keyboard at all.

Any clues as to the issue? I'd love to be able to just connect without spending 2 minutes doing so every time.

How can I print web pages from my Android to a wireless Printer?
There is a system I log into online that generates web pages for a printing. This works great on the PC using Chrome, Firefox and IE.

I would like a way to print these web pages from the tablet (Galaxy 2, Android 4). Unfortunately, these web pages I am referring to require me to be logged in. Many print apps I have found simply re-visit the URL without using my login credentials. That will not work for me.

The best solution I have found was to use Firefox's save PDF feature, then open the PDF with the Cloud Print app, which would then print to my PC or one of the Google Cloud ready printers.

Ideally it would connect using WiFi or Bluetooth, but the Cloud Print over Internet idea is good enough for now.

Unfortunately it takes 7 clicks at this point (menu -> tools -> save pdf -> open status bar -> open the pdf (at this point Cloud Print is set as default) -> click print (with default printer) -> click back to go back)

Not to mention, there will be many pdf files just sitting on the phone that should eventually be cleaned up.

Can you recommend a better solution?

How can I install the UPS Mobile app in Sweden?
If I visit the American version of the Google Play Store while logged in I can search and find the app. But I am met with a message that says I can't install it.

This app is incompatible with your [device name].

There's also an additional line if I click the little plus button which gives some sort of explanation.

This item cannot be installed in your device's country.

I'm not really sure how to tell if I am on the American version of the Google Play Store. My Google interface language settings are set to English, and my Google searches usually return web pages in English. It seems as if you can't set the search result language to be anything else than English if you are using English as interface language with Google products. And besides, the "localized" Google Play Store for Sweden is in English too. So how do you tell them apart? It beats me!

I should mention that I was unable to find the app when I did a search for it on my Android device using the Play Store app. So does this mean it is restricted for users in Sweden? And if so, how can I trick it to install anyway? I tried finding the APK file for the app for manual installation but all the websites that host the file are bollocks! They require registration and some of them just point to the Play Store, and what not...

I use UPS on a daily basis. I am clueless as to why they would want to block their customers in Sweden from using their app. What do they have to gain with that?... this is no music or video service we're talking about, there should be no licensing bullshit involved here.

I did check the system requirements and my device should be supported. So I don't think that's it.

Is anyone else, outside the US, able to install this?...

Why can't I access the files on my SD card?
I have a Motorola Droid Bionic which I recently updated to Android 4.1.2. Since the update, I can no longer access any of the files on the 32GB micro SD card I installed in the phone. I can view all the filenames and directories, but when I try to open any of the files, I am unable to.

Settings -> Storage tells me that the SD card is mounted at /storage/sdcard1

I had previously enabled "Memory card encryption" under Settings -> Security & Screen Lock -> Data encryption, and I believe this is likely the issue. I must have enabled this over a year ago, likely shortly around when I first got the phone.

I just noticed this issue a few days ago. I did the update last week. I am not sure if the update caused the issue, but it seems the likely cause because it's the only thing I have changed recently.

Trying to play music from the SD card (in three different players) displays the error "Could not play this track" for every song. Trying to view images on the card displays the message "Could not read file".

The phone is not rooted. I have a pin enabled which I need to enter when the phone boots and on the lock screen.

I have a Garmin Oregon GPS device with a USB port. When I connect it to a Windows PC, I get two drives: one for the internal memory and one for the removable SD card. When I connect it to an Android tablet (Asus TF700T, running Android 4.2.1) I get only one drive 'USBdisk1' which represents the internal memory. How can I mount the second drive?

I suspect that both drives are properly detected by Android, but just the first one is mounted. I conclude this because when I attach it again to the PC, both drives have a new LOST.DIR folder created by Android. Btw, the filesystems are FAT and FAT32, so that shouldn't be a problem.

On my rooted Asus pad, I tried modifying /etc/vfold.fstab from:

```<code>dev_mount usbdisk1 /Removable/USBdisk1 auto /devices/platform/tegra-ehci.2/usb1/1-1/1-1.2 /devices/platform/tegra-ehci.2/usb2/2-1/2-1.2 /devices/platform/tegra-ehci.1/usb1/1-1 /devices/platform/tegra-ehci.0
</code>```

To:

```<code>dev_mount usbdisk1 /Removable/USBdisk1 1 /devices/platform/tegra-ehci.2/usb1/1-1/1-1.2 /devices/platform/tegra-ehci.2/usb2/2-1/2-1.2 /devices/platform/tegra-ehci.1/usb1/1-1 /devices/platform/tegra-ehci.0
dev_mount usbdisk2 /Removable/USBdisk2 2 /devices/platform/tegra-ehci.2/usb1/1-1/1-1.2 /devices/platform/tegra-ehci.2/usb2/2-1/2-1.2 /devices/platform/tegra-ehci.1/usb1/1-1 /devices/platform/tegra-ehci.0
</code>```

...this was just "try and error" and it ended with a severe error :)

What are the correct (auto-)mount commands?

Play store stuck in old country
I moved from France to Italy, and it seems like my Play Store is stuck in France. The Operator is recognized correctly as Vodafone on the play store, but I still see the app recommendations in French and some Applications which should be available only in Italy are not downloadable (This item cannot be installed in your device's country)

How do I get play store to recognize that I have moved to a different country. My phone is a factory unlocked Galaxy SIII GT-I9300 with stock OS, purchased in France.

Restoring Samsung GT-P1000 to original firmware
I spent the past several hours reading and reading. I tried to upgrade this Tablet to Jellybean, now the Tablet only reaches the Samsung glowing screen.

I tried several fixes to no avail, my first hurdle is I have no idea what Product code to place in to get the firmware from Sammobile as I dont know where this tablet originated from, possibly England. I also followed a tutorial on how to restore back to gingerbread 2.3.3 which gave me the same result; I think I have to go back to Froyo 2.2.

So I followed the tutorial from the answer on Restoring original 2.2 firmware on Samsung Galaxy Tab GT-P1000L.

Again no luck, I think I need to restore everything. As I'm a noob maybe someone can point me the right direction? Also in the above tutorial I downloaded some PIT files, and I have no idea which one to use. Picking the correct firmware from Sammobile and PIT should reverse everything as I did load a modem file in the first place.

A few Questions about Recovery
I tried to install ClockworkMod recovery using Rom Manager but my device was not listed on the supported versions. So I tried installing ClockworkMod for a different device using the commands shown here. Now I can't boot into recovery mode, but the phone starts up normally.

So I thought of backing everything up before trying anything more with the phone. I found this guide which has instructions on how to back everything up. But my filesystem doesn't have a file /proc/mtd as mentioned there.

Can someone point out a way for me to find those partitions?

After searching the file system in the phone I came across a file /cache/recovery/last_log. Thinking that the file would prove to be useful I have added the contents in this pastebin. Can someone explain to me the contents of the file and how it can be useful to accomplish what is mentioned here?

As I have mentioned earlier, due to my efforts to install ClockWorkMod recovery, the phone doesn't boot to recovery mode. Is there a way to use the mentioned data in order to fix that? (Maybe backup the data as mentioned in the link and restore them using some terminal commands using adb?)

After looking at the contents, I tired the command busybox mount /dev/block/mmcblk0p16 /mnt/sdcard/recovery-test and it returned the error mount: mounting /dev/block/mmcblk0p16 on /mnt/sdcard/recovery-test failed: Invalid argument Can someone explain to me why this happens?

3G connectivity lost; reboot required to restore it
Similar to this question, but slightly different/worse:
Restart data connection when stalled?

Every so often – usually every day – I'll lose data connectivity (the icon in the status bar goes grey). Sometimes I can restore it simply by toggling the data connection on and off, but more often this doesn't work and nothing short of a reboot will actually restore it.

I can live with having to enable/disable it every now and then, but having to reboot my phone is a real inconvenience (especially as it's encrypted and requires a password to boot).

Is this a hardware, software, or network issue, and is there anything I can do to fix it? I'm running stock 4.1.2 on a Nexus S.

Task management software that will sync with GTasks and exchange?
I am trying desparately to find an app solution to manage all of my disparate task lists. I work for two companies, both supply me with exchange credentials and a phone (one iphone, one blackberry). Both sites run through exchange. My personal device is a Samsung Galaxy S3.

For personal tasks I have been using Astrid, but I am unable to get my outlook tasks that way. I have heard people suggest using touchdown, but that would create yet another task manager that I'd have to tangle with. The solution I am looking for is something that would either:

Sync exchange at each site to google tasks, which astrid would then sync on to my personal device.

Allow astrid to directly pull down tasks from the exchange servers

Provide some other 3rd party task manager which would sync with google tasks, and both exchange servers.

I am using a mac, so sadly the outlook sync for google apps program won't work (it's windows only, and only compatible with the windows version of outlook).

Any recommendations on how to accomplish what I'm doing? Right now I am missing tasks because I have to juggle 3 different devices to get everything, and it's having a pretty big impact on my productivity.

Samsung VG-KBD1500 keyboard pairs but not connects to Nexus 7
I can pair my Samsung VG-KBD1500 keyboard to Nexus7, but it doesn't connect to it.
The keyboard works well with the TV, and I have another bluetotth keyboard, that paired and works well too.

I disconnected the Samsung kbd from the TV, and switched the TV off

Paired the Samsung keyboard to Nexus 7 successfully

When I tried to write something, the softver kbd shows up

The other bluetooth keyboard works well if I take it on.

The same issue occurs, if I unpair the working kbd and Samsung kbd and repair only the Samsung's one.

By opinion of Samsung support, the kbd should work, but it can be paired only with one device at the a time, but it doesn't in my case.
Any advice?

Rooting EPad MX1014
I have a E-Pad MX1014 (chinese tabcrap) and I am trying to access the system apps so I can uninstall Angry Birds off it.

The Angry Birds it runs is an extremely old version and for some reason it will not update it. I have tried installing different versions like Angry Birds Star Wars or Seasons and trying to just install the Angry Birds app over the top with no luck...

I cannot access the device via USB because the "adapter" to change from the current plug to USB has died. I have been using SnapPea via the wifi to put apps and such on it.

I have tried Z4Root, GingerBreak and tried getting BusyBox and SuperSu onto it, but I keep getting cannot install errors and missing binary errors... Z4Root when I hit root (either temp or perm) will say it's rooting it then go to home screen and nothing else happens.

Does anyone have any suggestions? The tablet runs Android 2.3.

P.S. if I had the money I would buy a better tablet, but this is just for my son and he is an angry bird fanatic....

I want a sound to be played when the user presses the power button, Since I am customizing Android for Visually Challenged people this feature might let them know if the tablet has actually powered on or not.

This feature is by default switched off in my firmware. And also I think that since this sound comes just when the device is switched on, that is, before the Android Boots, the power on sound should be a function of underlying Linux kernel.

Any clue how to go about it and turn it on. Thanks in advance.

问:
Why does my Droid RAZR play the new email notification when I visit my inbox on my PC?
This is truly a mystery to me.  When I get new email, it's normal for me to receive an audio notification on my Droid RAZR.  However, when I visit my Gmail Inbox via my browser on my PC, my Droid RAZR plays the notification sound.  I'm not even really sure how it knows what I'm doing.  I realize it's connected to Gmail, but it's still quite strange.

This morning I sat down at my computer to find I had several new emails.  I began reading and managing them in Gmail (on my PC), and during this time my phone notified me of new email at least 3 times, yet I didn't actually receive any 'new' email at that time.  It was all because I was going to my Gmail Inbox.

How does my phone know that I've done this?  Sometimes I don't even really have to DO anything.  If I already have a browser tab with my Inbox, and then at some point I simply go to that tab and there happens to be new email in it, within a few seconds my phone will notify me.  It's quite bizarre.

What is the explanation for this?

Recent example:
I was just browsing the internet on my PC when I noticed I had some incoming emails (my phone played the audio notification, and I also can tell via my gmail notifier app in my system tray). I was watching YouTube videos at the time.  After a few minutes I left YouTube and went to gmail.com, to my Inbox.  I clicked to view the first unread email there.  During this process, my phone played the incoming email audio notification not just once, but twice.  This is before actually doing anything with any email.  All I did was view it.  I really don't understand why/how this happens.

Update to recent example:
After updating this post with the recent example I just gave, I went back to my Inbox tab (yes, I had left my Gmail Inbox open in another Firefox tab).  When I went to the tab, which still contained a couple unread messages as I had not viewed them all yet, my phone played the notification AGAIN.  I really want to know why this happens.

Ainol Novo 10 Hero 2 bricked?
Attempting to update my Novo 10 Hero 2 appears to have gone seriously wrong somewhere along the line, to the point the device won't boot and appears completely dead. The computer isn't recognising it when it's plugged in (as in it doesn't even recognise there's a device attached) and booting into recovery mode by holding volume up + plugging the USB cable in doesn't do the trick either. The screen doesn't light up, it doesn't make any noise - it's completely and utterly dead, or at least appears that way.

Is there anything else I can try, such as perhaps booting from the SD card, or is it completely unusable now?

问:
How can I fix my corrupted /data partition?
The following happened. I have a Galaxy Mini Plus (S5570I) running Android 2.3.6 which I've been using without problems so far. Recently, I've installed an APK (Opera Beta), which somehow caused the device to freeze, so I had to pull the battery out and restart it manually. Upon switching it back, the device stays at the pre-boot screen, and constantly displays the "Samsung Galaxy Mini" logo, the one that's supposed to show up for seconds before the boot animation. No amount of waiting or restarting helps, it's completely bricked for some reason.

However, if I try to restore a backup via Clockworkmod, or try to erase the information, I immediately receive an error saying Error mounting /data! or Can't mount /data!. Every single other partition loads and is mountable, except for /data. Which renders backup, restore, or delete impossible.

Is there a way I could manually rewrite the partition table (i.e. recreate the partitions) or somehow get the device to boot, preferably without sending it in for repair? Clockworkmod doesn't work, stock service mode doesn't work, Odin doesn't work, I can't even get adb connected.

(I live in Iran and Google does not allow me to use play store features). So, I bought a vpn account from Germany, connect to it and download and update to play store. Everything is okay.

After 3 months of using my phone, everything was fine. Last week I restored my phone and all data has been removed. And after setting up a Google account I tried to update market place to play store. But problem is, when I try to start market place, it hangs on start screen, and just show white screen with loader in center of display, after 20 seconds it closed and returned to home screen.

I tried to connect with vpn connection (I thought it's because of country restriction again, but recently my country changed the laws and closed any connections like pptp, l2tp, https, ipsec. Now I just connect with my real ip)

Any help, any comment, any way to update and connect to play store?

问:
How do I get my HTC Desire out of the boot loop?
I just screwed up my HTC Desire. I had some low memory issues so I decided to power it off. I then went into 'recovery', and then 'mounts and storage', and then 'mount /sd-ext'. At this point it went all black, I guess in order to mount it, and showed me the menu again. I remember that an 'unmount' option appeared. I think I did 'mount /sdcard' then. I then chose reboot system now.

Since I did this, there is the HTC Quietly Brilliant white splash screen appearing and the phone is booting, I hear the HTC signature boot up melody, and then it starts to loop at this point. It doesn't stop until I pull out the battery.

The phone is rooted, s-offed, has stock ROM with Sense, and AlphaRev Recovery.

What should I do to make it boot again? I don't want to do any formatting or data wipes. I have unsaved personal data. I don't have a fresh backup.

Update:

I have managed to boot it now. I used both options in CWM recovery to wipe both regular "cache" and Dalvik cache. And then I chose to rebooted. It took very long time to boot.

I am presented with following problems now.

There is this message saying

Not enough storage space for SMS/MMS

Your phone's storage is almost full. You...

Crash

The application Google Services Framework has stopped working
  (process com.google.process.gapps) has stopped unexpectedly. Please
  try again.

Crash

The application Facebook (process com.facebook.katana) has stopped
  unexpectedly. Please try again.

Low on space

Phone storage space is getting low.

Missing apps! Google apps are apparently not available. I think this has to do with that Services Framework thing crashing. There were some other apps crashing as well, I think they were just some minor apps, I didn't catch on to note them down, apps were crashing like on a production line.

The reason why so many apps are missing I think is because I used an app called Link2SD which makes symbolic links for Dalvik cache, libraries and for the APK of apps. It moves these to the SD card, and tricks the system into thinking that they are present on the internal memory. I don't see the Link2SD app icon any more. Can I recover these somehow?...

Where do I go from here? Do I rescue what I can, or do I try to fix the problem? Essentially, do I save myself or do I extinguish the fire?

Update:

I had to manually install Play Store using ADB from the computer. I used it to download and install the missing apps I needed to backup the most important data. I then flashed a new custom ROM on the phone.

How to use Sony Xperia Z's burst mode programatically?
I'm trying to trigger the Xperia Z camera in burst mode based on an event and I'm not sure what the best approach is.

问:
Mobile data is disabled, but some data is still transmitted
First of all, I've read several similar questions here, but they are either not related, or require root access (Droidwall and stuff).

I received my Google Nexus 4 a week ago, and enjoying it so far. One thing is bothering me though.

I have access to Wi-Fi pretty much whenever I need it, so I'd like to disable any mobile data usage, at least until I figure out a nice data plan.
So the first thing that I did was unchecking Mobile Networks > Data Enabled and Data Usage > Mobile Data (I believe, these are the same thing). Now, the usage graph is empty. However, my carrier's report shows several records (6 in 2 days) of low mobile internet usage rounded to 100kb each. Cost-wise, it is equal to about 1 minute of talking.

I could probably live with that, but I have a trip to another city in a few days. If it happens while I'm in roaming (although Data Roaming is also unchecked), it will become much more expensive.

And so, the question is: how do I block mobile data for sure and let all the apps only use the Wi-Fi connection?

Non-rooted Google Nexus 4 running Android 4.2.2

Possibly relevant options:

Data enabled - off

Data roaming - off

Restrict background data - off - I use skype and imo.im, so it's nice to have them update in background

Auto-sync data - on

Keep Wi-Fi on during sleep - always

I was using my LG P500 perfectly fine on the internet when all of a sudden a messaged flashed up on the screen internet disconnected.

So I went into settings to my wireless & network settings and turned off my WiFi, then turned it on again then went into WiFi settings. When I went into here there were no known networks showing up and the scanning wheel was just going round and round.  So I thought since I know the pass word, I will just add a new network.

Then my WiFi turned off on my phone. So I rebooted my phone and again this is still happening. It is not just at my house but everywhere I go I cannot connect to networks. :(

问:
"Contacts' birthdays and events" calendar does not update on S3
I have a Samsung Galaxy S3 with Android 4.1.2.

I have several calendars which I access through S Planner and it all work fine, except for "Contacts' birthdays and events". It shows the events and all, but if I change some birthday, or add a new contact with a birthday, the change doesn't show in the calendar.

On Google calendar, they are updated just fine.

I've found that if I clear the data of "Calendar Storage", it syncs again, and the events are shown properly. But then again, it doesn't update any new changes. Also, all the info not stored on Google Calendar, like tasks, gets deleted.

Amazon Appstore reports "payment issue" when I try to update an app I bought a while ago
I remember having this issue months, possibly years ago. The error message is poorly worded and I forget what I did to resolve it last time...

http://note.io/1818dqP

Clicking the link takes me to a page (in the browser) that says that the digital orders page has moved, with a link to the new location. Following that link just shows me my order history and the "pending orders" that the app alludes to don't seem to be available anywhere.

My only thought for a resolution was that maybe it was looking at one of the expired credit cards I lazily hadn't removed from my account yet. I removed all expired cards, and I still have the issue.

What's most frustrating is that this is an app update. It should be completely free.

Anyone got any ideas?

Until recently I was able to manually link a Facebook contact to my android contacts by going into the Facebook contact, holding down the contact under the friends list then selecting 'link to phone contact' (or something very similar).

Limited space and Full SMS memory
I am getting a message that the internal memory space is full. I checked that I have 15MB intenral memory left and 50MB on my SD card.

I also get a message that the SMS memory is full. I deleted some messages but this message doesn't seem to leave!

All these happened when I safely removed the SD card.

What can I do to remove these messages, which I don't believe they are for real. Something nasty must be going on here. Not to mention that before I removed the card the internal memory was about 30MB.

I tried to erese the cache by using memory wipe aplication but nothing really happened.

Any ideas?

EDIT

I tried to move some applications to the SD card through the Application Manager but the option move to SD cannot be pushed, although there is some space in the sd card(~50MB). I tried to move on application with 1MB size in my ~50MB free space SD card...

Does this imply a problem?

Nexus4 not sending touch-tones to other end of connection
Brand new Nexus 4 (shipped 1 week ago), unmodified software/hardware straight from the box (except for APN settings) No new apps loaded. Connected via Bluetooth to an ATT TL92429 cordless phone system. System works fine for making and receiving voice calls. However, if the number called requires touch-tone entries  (eg, voicemail), it appears that only the first keypress is transmitted. After that, the far end of the connection does not receive the tones. This problem does NOT occur if the phone is used directly (ie, not via bluetooth connection to the cordless phone). Furthermore, the same ATT cordless system when connected via Bluetooth to my (antique) Moto E815 does not suffer from this problem, so I suspect the fault lies in the Nexus4 software. I'd be grateful to receive any suggestions/guidance/patches to alleviate this problem. </p>

troubleshooting email forwards not being sent, but no error message
I'm hoping someone can shed some light on this problem. My co-coworker has an ICS Android and is using the stock email app for our exchange server. When he forwards an email that has an attachment, it keeps getting stripped out. I'll give you some of the steps I've already gone through.

I can send attachments of various types through my phone, granted I'm on JB.
 --should rule out server/global issues
I tried sending different types of attachments, small and large from his phone.
 --not a file-type issue or file-size issue
I verified that the attachment showed on the email draft.

Now that I think about it, I didn't look at his sent. I'll check that tomorrow.

What am I missing here? I'm hoping this is a simple setting issue. Would it help if I tried to get a log? I'm not quite sure how to get the log for the email app.

Galaxy S3 Mini drains excessive battery when Wifi is ON
This question is linked to this one: Wifi battery saving tips or automation

This time, the question is different.

I have here a Galaxy S3 Mini phone that behaves strange. When Wifi is OFF, battery takes a lot of time to drain. When Wifi is ON, battery takes up to 4 hours to drain.

I have a personal Galaxy S3 "Large". As we all know, wifi increases power consumption. But not at that crazy level. My S3 consumed little less than 40% its battery power when the other phone was at 15% of remaining charge.

The battery monitor indicates that "Android operating system" takes 67% of the consumed power with a high CPU usage. When wifi is disabled that does not happen. The phone is rooted. ROM is I810NXXALL6, version 4.1.2. At the current time I don't remember exactly how I rooted this phone, but I can remember I flashed a stock no brand ROM.

I would like to ask if this behaviour:

May have been caused by hardware damaged (which means phone is to unroot, de-odin and send to repair)

Edit: Some facts integrated from below comments (by Izzy)

factory-reset (done via the recovery menu) did not help

what broke it was most likely increasing the screen resolution (DPI?) too much, so the config now holds invalid values (does anybody know if that is revertable e.g. via recovery menu + ADB, or something alike?)

No web access on Android 2.3.7
I have an LG Optimus V, rooted, with Cyangenmod 7.2.1 (BackSide-IHO) that has developed, lately, a weird network problem:

While on 3G (or wifi) every app on the system with the exception of the two browsers on the system work perfectly. The browsers, which are Opera and the "built-in" browser cannot get to ANY webpage. They act as though they have no internet connection. Whereas I can fire up an OpenVpn tunnel via WiFi or 3G and it connects fine. Every other network-using app on the system also works fine on either 3G or WiFi.

I have the "SetDNS" applet and have changed from Sprint's DNS over Google's with it. This change was LONG before this problem began.

As I'm familiar with Linux, I've poked around via adb shell to see if I can suss out the weirdness, but nothing jumps out at me. Everything I do at the shell command line having to do with the network works fine. It appears the browsers have something misconfigured.. I have no idea what...

Does anyone have any idea of what it could be, or what else I could test -- and how to get the browsers work normally again?

Internal Memory getting low despite apps are moved out using Link2SD
There might be similar questions. I don't want to open those old question.

This is what I have done:

I have rooted my phone.

I have installed Link2SD.

It was working good. Suddenly I started to get interal storage full warning.
I uninstalled apps one by one. I got some space in internal storage. I got about 80MB. I should get 150MB. Anyway, I am now installing apps one by one. Whenever I install an app, the internal storage is going low. Once I moved the app using Link2SD, I am getting some space.

But the problem is, I am not getting the same amount of space. So if I install few more apps, the internal storage will surely go down and i will get warnings.

Clearing app data without waiting for it to be counted
When I need to clear an app's data, the "Clear Data" button is greyed out until Android has finished counting how much of it there is. Sometimes it never completes, and I need to force quit Settings and try again.

This is, obviously, a complete pain.

Given that I don't care how much data the app has stored — I just want it to be zero bytes — is there a way to force Android to enable the button and let me clear the app data without waiting for it to be counted first?

(I have a Nexus 7, which updated to 4.2 pretty sharply after I got it, so I don't know if this is a 4.2 bug or a poor design decision which has been around for ages…)

Do Android devices become slower with time?
I own a Galaxy S (2.3.5 / GT-I9000 / BVJV3) and use it since two and a half years. I also have bought more recent hardware, like an iPad Mini and a more recent Android tablet, which comparatively are much more reactive.

So I was wondering if the slowness of my device was just a feeling, or if devices actually become less responsive with time ? The phone is always lagging (click sounds always a second behind), running the basic functions of the phone (messages, phone, contacts) always need a good 4 seconds to actually show on screen, returning to the home screen sometimes takes 5 to 10 seconds while it's doing something to the icons.

When I put the full card in my laptop to transfer the pictures, at first it worked. When I went to open the card, I could not find it anywhere on my laptop. I removed it and put it back in my phone and it is now saying the card is damaged. I have tried both multiple times, even in my camera, and still have not been able to find my pictures.

What can I do to find my pictures again and safely?

Do any launchers restore home screen widgets from Google backup?
Are there any custom/3rd-party launchers that, when you have Back up my data turned on in the Backup & reset settings, restore home screen widgets when a backup is restored? I know the stock one doesn't, so I hope that someone with more experience of 3rd-party launchers will recognise the behaviour.

Double message notifications after upgrading Talk to Hangouts (CyanogenMod 7.2)

Phone: HTC Wildfire

OS: CyanogenMod-7.2.0-buzz

I recently upgraded Talk to Hangouts, and now each incoming message results in two notifications: one styled like the old Talk, and one from Hangouts.

I tried rebooting the phone, as suggested by Getting double message notifications after replacing Talk with Hangouts, but the problem still persists.

Looking through the lists of installed applications and running processes, I only see Hangouts, not Talk.

I considered completely uninstalling both Hangouts and Talk, and reinstalling Hangouts, but the application manager only gives me the option of uninstalling the updates for Hangouts, and reverting back to the system's built-in version (of Talk, presumably).

How can I stop the double notifications, or troubleshoot this further?

Lock screen unactive for 8 seconds - Exchange security setup on Android 4.1.2
Can someone reproduce this issue.

I have setup exchange account on my SGS2 with Android 4.1.2. When you setup exchange on android it is required by security policy of exchange server to have screen lock on - in my case it is secured with PIN.

When i try to unlock the phone, my screen is not active, i can just wait and after about 8 second it responsive again and i can unlock it. This doesn't have every time. Let's say 5 times/day .. probably some issue with light sensor.

Please don't post solutions like "You can install 3rd party program ... ", i want to have this security enabled.

Thank you.

How to save an image displayed in the stock browser without downloading it a second time?
I am trying to save a scanned image from a printer on the local network with the stock Android browser. The browser interface looks something like this:

As soon as I click "start scan", the printer begins scanning the image. When complete, it is displayed in the little box on the right and a message pops up near the bottom instructing me to right-click the image to save it.

Now, in the stock Android browser, long-pressing on the image displays a menu which provides an option for saving the image. Unfortunately, the download always fails - and I think I know why. The printer does not keep a copy of the scanned image and immediately deletes it after the browser finishes loading it. This is a problem because the Android download manager will attempt to download the image a second time.

How can I save a copy of the image that is already displayed in the browser? Chrome and Firefox for Android both use the built-in download manager, so using them made no difference.

Some Android contacts with phone numbers are missing after update
After I updated my Sony Ericsson Xperia Mini Pro from Gingerbread to ICS some of my contacts went missing. The strange thing is when these people call me, the phone recognizes them and displays their name, but I still can't view the contact. When I touch-and-hold on a name in the call log and choose "View contact" nothing happens. Touching once though calls them right away.

Also in the contacts list ("Contacts with phone numbers" is checked), where the rest of my contacts are listed, nothing happens when I touch a name. It should open up the contact. So now I can only call people who are in the call log.

Can anyone help me?

Samsung Galaxy Fit firmware update fails
I have a Samsung Galaxy Fit, model GT-S5670B.

When i connect the phone to the pc, Samsung Kies (version 2.5.3.13043_14) identifies that there is a firmware update available.

I agree to do the upgrade and follow the instructions which basically are not turning off nor disconnecting the device and wait. At some point, after downloading the firmware files i believe, the update just throws an unexpected error and stops. I have the option of trying and restoring my device and thats it!

There is no feedback nor message whatsoever about what the error was and why it happened. And also, even if i don't restore my device and just reboot it, it is okay as if nothing had happened so i believe that the installation of the firmware didn't event begun.

Anyone knows how i can upgrade my Galaxy Fit from Android version 2.2.1 to 2.3.6? Or what the problem with Samsung Kies is?

Already tried to uninstall and reinstall Samsung Kies but nothing changed.

Thanks in advance!

TecTiles and applications
Samsung promotes NFC via its TecTiles, which is a very interesting concept but i cant find lots of information about it, especially the need for an app.

Do you know if a user that just want  to "read" the tag needs an app (probably this one) on his side to be able to execute the action?

Does someone have experiences/feedback with this product?

Hacking frequency range in tuner
I have a Samsung Galaxy S3 with FM Tuner application. It is rooted.

I also took a look at Spirit FM Unlocked.

My question is: provided that this is illegal in some countries and not in others, and that AFAIK aviation frequencies are amplitude-modulated (AM), is it possible to (first and foremost) listen to radio frequencies beyond the 87.5/108 MHz standard ranges? Then is it possible to listen to AM frequencies wit Spirit FM or any other radio app after hacking the range?

Obviously, I just would like to listen, and fortunately it's not possible to interfere with a simple Android device into these frequencies.

I tried to root my Galaxy s2 Sprint. I turned my phone off and went to downloading mode, then I turned the odin and connected my phone to pc. After it, i hit start and nothing happened except saying "do not turn off the target." So I waited an hour and nothing happened or downloaded.

I tried to go back to downloading mode but it didn't respond. Now I can't turn it on or charge. When I stated to root my battery was full.</p>
