[Android Apps and Games] A++ Apps:
Hi everyone,

I have just had my first app developed and released, there is a fully functional Trial (Widgets not included in trial - Sorry!)

The app provides a simple way to lock your phone on a as-needed basis. It uses the Android PIN lock screen with a pre-set 4-6 digit PIN.

The clever part is it deactivates the PIN lock once the correct PIN is entered.

There are two widgets in the paid version to select - "Standby/no-lock" activates 'swipe' screen lock only

or "TempLock" which performs the lock described above

If you are interested please check it out on the Android "Play" market:

"Temporary Lock" or "Temporary Lock TRIAL"

Any suggestions/comments/feedback would be much appreciated!

Or even better if you like it please give it a 5 star rating!

Thanks heaps!! Reece - A++ Apps

Is there a difference with dpi settings between ics and jb? If so what are they?

Thanks
[Galaxy Tab 2 Q&A, Help & Troubleshooting] scottx .:
No. Both are mdpi, 160 dpi.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] sloosecannon:
However, the JB version will turn your tab into a "phablet" UI w/ a drag down notification bar, but the DPI stays the same. In case that's what you meant.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] mymeatb18:
Just asking cuz I thought some apps looked a lil different I guess just my imagination but thanks for the info
[Galaxy Tab 2 Q&A, Help & Troubleshooting] sloosecannon:
Nope not ur imagination... the switch from tablet to "phablet" means apps that were dual-paneled become single-paneled
[Galaxy Tab 2 Q&A, Help & Troubleshooting] dskiller:
I like the dual-paneled better though................
[Galaxy Tab 2 Q&A, Help & Troubleshooting] sloosecannon:
Yup same. That's why I set aokp to have it dual paneled ;). Not sure what u can do on stock other than modifying build.prop to force it. But that'll cause other problems
[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
Tried booting holding down the volume down button and power simultaneously and am able to select recovery mode but I just get a screen with the white Google name - recovery mode never starts (I have waited minutes) and I have to hold down the power button to get back to a normal startup. Also tried connecting to my PC via USB and booting holding down the power and the volume up and down buttons simultaneously. Then I get the belly-up Android and the Start selection but the volume keys don't change the selection and the power button does not cause a start - I have to power down by holding the power button in and restart normally. Any ideas?

[Nexus 7 Q&A, Help & Troubleshooting] adamhlj:
You can use one of the root tool to reflash recovery mode if you don't know how to use ADB (which I don't really know.) You can flash CWM or TWKP or whatever it is. Then you should be able to do whatever you need to do. I have used the galaxy nexus tool kit v7.0.
[Nexus 7 Q&A, Help & Troubleshooting] AMoosa:
Connect to pc

Shut down nexus 7

Hold volume down and power

At the next screen, press up until it says recovery mode

Press power

You then get the Android with red exclamation

Press power, hold it and then press volume up

This should give the recovery menu.

Result!
[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
As I noted, I tried this and at the "At the next screen, press up until it says recovery mode" point, when I press the volume up button nothing happens, it stays with Start displayed (and pressing Power at that point has no effect - I have to press and hold Power for many seconds to force a shutdown).
[Nexus 7 Q&A, Help & Troubleshooting] poisike:
You need to press volume up a few times, until you see Recovery.

This guide worked for me, so thanks AMoosa.
[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
Yes, I said I tried that and pressing volume up has no effect - it stays at "Start" and even pressing Power at that point has no effect, I have to press and hold power to force a full shutdown.

[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
One update - I could get to recovery using adb (adb reboot recovery) but once there adb could no longer see the Nexus (adb devices showed null). Have to try some more when I get home from work tonight.

Manual update to 4.1.2 is original reason for doing this but now I'd like to understand why I can't get to recovery mode the "standard" way.
[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
I meant through the menu selection on the Nexus itself, not through adb. And as I noted, once I got to the recovery screen, adb could no longer see the device.
[Nexus 7 Q&A, Help & Troubleshooting] sparksd:
Well, with 4.1.2 (OTA) I can now get to the recovery screen by using the simultaneous power + volume button pushes, no adb required.

On the final set of workaround instructions, it says "4. Select Recovery using vol buttons and press power button" - I could not "Select Recovery" because at that point my Nexus would not respond to any button pushes.

[Nexus 7 Q&A, Help & Troubleshooting] jonjvaughn:
Though a series of misadventures I now have the saem problem as the OP of this thread where i can no longer get myself into recovery mode.

I had just doen a full backup and flashed a new version of the kernel when this occurred. Please don't tll me to use my volume keys to select Recovery. As the OP said, the keys no longer work. Theydid once but no longer. My N7 is stuck on the picture of Andy belly-up with Start shown but I cannot scroll up or down nor hit the power key to Start.

I download the file from two posts up but not sure what to do from there. FYI, I was fairly familiar with the ins and outs of Andoird, ADB, etc a year ago when developing apps but I've since retired. DO I need to get the downloaded file onto my device in order to use ADB to perform the fastboot commands above? Could someone please enumerate the steps for me to give me a jumpstart?

Edit: Whew! I got a tip to use Mskips' nexus 7 toolkit and got back into recovery and restored my backup and all is well so far. Knock...knock

[Nexus 7 Q&A, Help & Troubleshooting] bmschech:
I have the same--or at least a very similar--problem. I was trying to flash it back to the factory default with Nexus 7 toolkit. In the middle of the process my computer froze and I was forced to reboot. Now when I try to enter recovery I get a tiny "booting failed" in the upper left corner of the screen and nothing more. I can't see my N7 with my computer via USB or adb. I'm at a loss. Any suggestions?
[Nexus 7 Q&A, Help & Troubleshooting] tcat007:
Exacty what happens to me. Trying to manually upgrade to 4.2 without root. I have update.zip on my n7. Do I need usb to be plugged into pc? I tried it both ways... when usb was plugged in I got past the red explanation mark, with option to install from adb, but not from sd. If not connected, nothing past explanation mark.

Probably just wait for ota... don't want to mess anything up.
[Nexus 7 Q&A, Help & Troubleshooting] bmschech:
Can't see my N7 with USB or adb

I posted this question above, but as the response to another person's post. Excuse me for repeating myself, but I was afraid that some folks would miss my response, so I'll ask my question again. I'm that desparate.

Basically, my attempt to flash the factory stock rom with toolkit was interrupted in the middle. Now my device is not visible to usb or adb. When I try to boot it into recovery it takes me to a screen with the words "booting failed" in a tiny font in the upper left corner of the screen with the Start menu on the right. All I can do is power it up or try again and always the same thing. I'm afraid I've trashed my device, which I didn't think was possible. Is there anything at all you can suggest I try (short of buying a new N7)?
[Nexus 7 Q&A, Help & Troubleshooting] sledge3n8:
I figured it out! If you installed the stock 4.2 update then you probably lost root. You have to install the updated SuperSU, http://download.chainfire.eu/267/SuperSU/CWM-SuperSU-v0.97.zip, to regain root and then install the updated boot loader from here: https://www.dropbox.com/s/u269wra01bnyhv7/JZO54K_bootloader.zip

Fastboot: Turn on Nexus 7 holding vol+ and vol- and power button. When you get into fastboot, plug Nexus into PC.

From this point fire up the Nexus 7 toolkit and pick option 10 (something to the effect of temporarily write recovery image and boot).

Once in `temporary recovery` then install the new SuperSU you just downloaded. At this point I rebooted and then shut down my Nexus again, went to fastboot, and then I booted into recovery a second time again using the toolkit.

I then installed the updated bootloader and rebooted again...all was good! I went into goo manager, wrote the newest recovery script, selected reboot recovery and it it booted into recovery!

I suspect that you can do the above in one step: use toolkit to get into recovery while in fastboot, flash the updated SuperSU and then the updated bootloader, reboot and smile! I didn't flash both at once so I can't tell you if that method works or not.

---------- Post added at 12:40 AM ---------- Previous post was at 12:28 AM ----------

I just confirmed that I can get into recovery by using vol+, vol-, power button method also.
[Nexus 7 Q&A, Help & Troubleshooting] Saturn1217:
Same problem...

I rooted my nexus 7 and installed TWRP to do it.

Then I wanted to get rid of TWRP and go back to the stock recovery.

I used ./fastboot flash recovery recovery.img using the recovery.img that is found in the factory image for the nexus 7

But now when I try to get into recovery from the bootloader I just get the little android with the red exclamation point. No buttons I press do anything except (I think) holding the power button restarts the device after a couple tries.

I just want a rooted device that will still receive OTA updates. I've run custom recoveries before and i hated it. I never knew which options in settings (like factory reset) were ok to use or if I should go through the custom recovery.

If I flash the bootloader image that comes in the 4.2.1 factory image for the nexus 7 will this fix the problem or make matters worse? I really don't want to brick my device but I'm assuming I need a recovery. Also could I just reflash TWRP?

(I am on a Mac btw if that helps)

Edit: Actually I was able to get into recovery but I had to be unplugged from my computer. So I think I am all set (I hope)
[Nexus 7 Q&A, Help & Troubleshooting] genman39:
I got stuck doing this and checked with google themselves for the procedure....the secret is to tap the vol up key rather than hold it just after selecting recovery mode.

http://support.google.com/nexus/bin/answer.py?hl=en&answer=2668187

worked perfectly...shame i lost all my data as in my case the n7 seemed to loose its launcher and simply wouldn't boot up...device is only a week old but I suspect I was the cause of the fault by using a file manager that gave access to the system folder and i maybe deleted something it needed......that will teach me.

[Nexus 7 Q&A, Help & Troubleshooting] strumpster:
I'm getting a similar thing.

I can't boot into recovery mode. The android toolkid can push a recovery onto the device, but I can never boot to it.

When I try to get to recovery mode, I just get the Google screen forever.. It doesn't even get to the red triangle :(

I also can't boot to the OS, all I can seem to do it get to fastboot mode at this time. I'm hoping I'm not out of luck completely.
[Nexus 7 Q&A, Help & Troubleshooting] hausman:
Edit: I'm pretty sure this is a hardware fault in my case. I installed the drivers and ran a fastboot oem unlock command, and the system hung forever on "erasing data". It appears that the motherboard can no longer communicate with the storage. I know the device is several years old now, but it is really frustrating that it just failed on its own. I have older stuff that still runs just fine.

(earlier post: )

I'm having the same issue out of the blue. I can't boot past the "Google" screen. If I hold power and volume down I get the options to restart bootloader, power off, start, and recovery mode, but recovery mode just goes back to the Google logo (recovery mode never starts). Forced obsolescence? I barely use this thing and it just died on its own within the last few weeks.

Hello All,

I would like to refresh the topic. and ask for support. I have ASUS NEXUS 7 and I tired to do HARD reset. Unfortunately during this operation when i choose option wide data factory reset and then tab was not able to move to another step (maybe i wait too short - 5 min) and i switched off. I tried one more time but now after choosing recovery mode tab is all the time showing "Google" screen so recovery mode never starts. Can i do something to start this recovery ? Could you support somehow? Thank you

Hi everyone,

I too would like to ask for advice. I have a Nexus 7 (2013) with lineage OS 19.0 installed. OS won't boot. I can load the bootloader by holding power + volume down. After select Recovery mode and confirm by power button, tab restarts. However, it only shows the white google logo for a few seconds, then black screen for a few seconds.. and repeats this forever. Recovery mode never shows up. adb does not recognize the device when in bootloader.

Any ideas on how to fix this?

Thanks

How long have you had your GNote 19.1? I have had mine for about 2 months and I only have 2 files in the .face folder.

.face folder

I've 110 files in the .face folder, almost all dated at the first days I had the GNote.

Couldn't it be something related to the "Smart Stay" function?.

Maybe they are sort of pics taken from the front camera to help the GNote identify your face and your eyes. Someone has not activated this function and so, for him, there aren't much files in the folder.

Just a supposition...

Ok... I guess I might have found out what causes the .face folder filling up wih files! It's "Gallery" application's "Tag Buddy" feature... as soon as I disabled it, it didn't re-create those thousands of files.

I had deleted them all and periodically checked if they would be recreated after opening any new application. I hadn't opened "Gallery" in a while, but it opened automatically when I reviewed a photo I had just taken... and guess what: as soon as the application started, the files in the .face folder started to reappear! After stubling around the settings and sub-menus and force-closing the app a few times to verify it as the cause for the .face folder choking up with thumbnails, I isolated the cause: "Tag Buddy"... a feature that I don't even know what it does! ...and for me, having a few thousand photos in the phone's tsansflash card (actually I have a Note II phone, but I guess some apps are on both devices... if not on even more Samsung tabs and phones) generated something around 28000 files in the .face folder, choking up the file system and therefore effectively even slowing down file operations!!! :eek:
