[Nexus 7 (2013) Q&A] danvee:
Google tech support would tell you to do a factory reset. Maybe twice.

If that doesn't work, return it.

Even if it cures it for a while, it may return.

That would be the sign of a possible hardware issue.

Google doesn't acknowledge or address the rebooting issues.

And Windows 8 has been a nightmare for some so far as drivers.

Google the Nexus 7/Win8 drivers issue, and you'll find a ton of possible solutions and no consistency so as to have one concrete answer.
[Nexus 7 (2013) Q&A] st33med:
Just did that. I didn't want to reset it because of the time needed, but I don't have much of other options.

So far so good. If it continues to reboot, it isn't a big deal. I'm eyeing the 32 GB version anyway to swap for as 16 GB is a bit cramped.
[Nexus 7 (2013) Q&A] danvee:
Don't beat your head against a wall. Keep returning until you get a 'good' one.

I can't imagine the number of refurbished units that'll be offered for sale as soon as the real issue(s) get(s) found and addressed (if ever).

Whatever happens, don't get stuck as a lot of us did....
[Nexus 7 (2013) Q&A] st33med:
As soon as I had posted that previous post, it had just rebooted after being put into sleep mode. Went back to Staples, got me the 32 GB one, and we shall see if this one works better. Hopefully it is just a hardware issue (I'm thinking the S4 Pro may have had a hard time with the low voltage on sleep mode) If not, I'm going to troubleshoot; maybe an app is causing the crash, maybe the firmware is creating issues, or both.

I'm keeping everything packaged for right now with the exception of the tablet itself. I've got a charger which works fine with it. Gotta love the two week return policies.

[Nexus 7 (2013) Q&A] st33med:
Curious, it looks like Chrome Beta may be at issue. I use it because I like being on the edge. I'll install Chrome Beta, see if the issue returns. If it does, I'm uninstalling it for right now (or just not launching it).
[Nexus 7 (2013) Q&A] berardi:
Try removing chrome
[Nexus 7 (2013) Q&A] muyoso:
I can confirm that chrome beta was 100% the cause of the reboots on mine. Gone a week without a single reboot after uninstalling, and I had about half a dozen a day when it was installed.
[Nexus 7 (2013) Q&A] danvee:
In my case, I've got Chrome rolled back to original and disabled and still have issues, admittedly the rebooting happens while asleep for the most part so that isn't nearly as intrusive as the frequent freezing.

Did it 2X just typing this...

can anyone advise? i want to install a custom rom and root my tf300t

i have unlocked it but now i need to install the mod twrp but apparently i need a pc. is there another way? via .apk file or something...

i then need to put my rom and gapps file on sd card, reboot to recovery and install the zip files right? and i am done????
[Transformer TF300T General] frankgreimes:
Yes you can do that, all you need is a "terminal emulator" app, there are plenty available just search for them. Depending on the custom ROM some already provide updated gapps so be sure to use the right one and not just the one given in tools like goomanager.

I would recommend the following.

1. Backup your apps + data using Titanium Backup

2. Boot into recovery and create a backup of your system

3. Wipe cache/davlik/data + system

4. be aware of the right "flashing order" FIRST the ROM file, then add more zips and choose gapps

5. enjoy your custom ROM
[Transformer TF300T General] pyraxiate:
Something tells me he hasnt rooted yet. If im not mistaken, he can't use a terminal app with the dd command if he isnt rooted. I know you can root using adb though with debugging enabled but im not sure he can root without a pc.

Here is a good place for him to start :

[LG Optimus G Pro] MobileNick:
I really like having the next alarm time showing on the lock screen since I rely on my phone as my primary alarm clock. This way I can just quickly glance at the screen without waking the phone to double-check the next alarm time.

On my OGP, this shows up when the screen times out before the PIN lock delay. But once it PIN locks, it no longer shows the alarm time. Is there any way to get this to show up even on the PIN lock screen? (ironically, my Galaxy S3 was the opposite - the alarm time only showed up in the PIN lock screen!)

[7" Kindle Fire HD Q&A, Help & Troubleshooting] olivaresfelipe:
Should I sell my rooted KFHD or wait for more stable ROM releases?

I recently bought a KFHD; I rooted it and installed AOSP CM10.1 It pretty much runs like a charm with the exception of the known issues and a couple of apps that are not very stable :confused:.

Overall, I love it: love the quality of the hardware, speakers, amazing Wifi reception, screen, battery life, etc. That said, compared to my Nexus 7, it is not as stable. I have to sell either one; I guess the question for me boils down to: should I assume that in the near future a more stable ROM will address the issues I have with my KFHD so that it runs as smooth as my Nexus 7?

If this is "it" for the KFHD, then I'm selling it and keeping the Nexus.

Thoughts?

Thanks in advance for your input.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] soupmagnet:
You shouldn't assume anything when it comes to future development. Any one of the developers can pack up shop at any moment and leave everything behind (a perfect example of this is the HTC Desire C).

If you aren't content with what you have right now, then you should probably go elsewhere.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] olivaresfelipe:
I'm sorry; I didn't mean to sound ungrateful. Very thankful.

That said, still wondering if based on precedence, I could assume the current stability issues in KFHD roms will be addressed.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] soupmagnet:
If it seemed like I was being rude to you, let me assure you that I wasn't. No apologies are necessary.

Hashcode and a handful of other developers in varying degrees are and have been working hard to bring the kernel up to speed with the 3.4.x kernel branch which would be needed for future versions of Android. However, it is all being done voluntarily in their free time and bugs are worked out in order of priority. If, say, Hashcode decides he no longer wants to work on it, development will be dead in the water until someone else with the appropriate amount of knowledge can pick up where he left off. Chances are, it would be the beginning of the end for Kindle Fire development.

Is it likely to happen any time soon? Probably not, but you can never be too sure in the world of Android Development. If you're looking for a sure thing for the long term, look at what you have right now and go with the option that you can live with as it is over the long term. Anything beyond that is a bonus.

Hello all -

I have recently relocated to the UK from the US, and I have a US Galaxy S3 (ATT) which is rooted (running CM 10.2) and SIM-unlocked. I have no issues using this with 3G networks here (TMobile) but would it also work on EE's 4G LTE network if I upgraded my plan, or would I require a different model to get LTE here?

TIA

[MDA II, XDA II, 2060 ROM Development] Keeper:
defroster, there's 2 versions: one where the video camera is rotated and one that is not. Their differences are:

mwilmar,i've been looking into this and i've also noticed the following:

Camera build 17082:

- if you set the save path of photos to your \storage card\, a error message will appear : "cannot find \storage card\" followed by: " Unable to save Captured image. 36001:500:10 " , and the phone freezes.

Camera build 17082 and 19307

- if you copy/paste the contents of the "Camera" folder into your \storage card\ root, they won't be recognized anymore has programs, no matter what you do. You'll need to delete them all and upload the Camera folder again.

I not shure but i'm starting to think that there is some misinstallation paths/ key entries on the registry and that's what is causing this issues...

example:

HKLM\Software\HTC\IPC\Album:

Path: Album.exe

HKLM\Software\HTC\IPC\Camera:

Path: \Storage Card\Camera\Camera.exe

Shouldn't they have the same path?
