Encryption.... Does it slow down the phone? - Nexus 4 Q&A, Help & Troubleshooting

I'm thinking about it as I got my old phone stolen and was stupid enough to not have any security apps and such so that was a loss. So now I'm deciding if I should. Does this slow down my phone?

There are other articles if you search google for "does encryption slow down android"

I'm curious to know how much of a performance hit the nexus 4 will take after encryption.... But I'm not testing that loll

I'm interested on trying this

I have a friend who encrypted his Nexus 4 and he says there is no noticeable slow down

OK I'm going to do it!
If I copy/paste to a PC my encrypted nexus 4 phone (to unencrypt it with a master reset)... Will I have some problems?

You mean like transferring files? There should be no problem
The encryption is more for protection against someone finding your phone when it's turned off. When you turn the phone on you are required to put a pin number in before it can even boot. One you have entered this you should be able to do anything a non encrypted phone can do

I'm actually having a lot of problems with 4.2 to Copy internal memory to my PC (using this "MTP" option).
this is off-topic:
For instance, now i have like 40 items on internal memory (40 folders) i'm trying to copy all of them (except sdcard folder) and when the copy/paste is finished, only half of them are passed to my PC. I'm started having this kind of problems in 4.2.X
So i wanted to know if encryption will make all this even more...problematic.

Tried with OS X too, and had the same problem....(too much time calculating the estimated time or preparing to copy...but when it starts..it only copies a few folderss).
I'm going to try to copy/paste with 4 selections of 10 items (folders) instead of one of 40 that always fails. As far as i see...the "android/data" folder is one of the main problems here.
After doing this...i'll try to encrypt my phone.

I failed you...i won't try this...because another thing ( i didnt know ) just appeared...
The reason: After encryption i won't be able to user Pattern Unlock. Only PIN or PASSWORD unlock.

There are security options available that shouldn't slow down your phone... I use TrustChip to secure my phone, and TrustCall along with it to encrypt my calls, or if I am sending a file for work. I don't need to be logged into a server to use it, so it doesn't drain the battery or slow down my phone.

I usually just use AirDroid instead of MTP, since wifi transfering seems faster than USB when using it as a MTP device, I kind of miss the old USB mounting style, least could be read/written directly.

nexus s vibrate

hey folks, just noticed my nexus won't vibrate at all. tried messaging settings and all options are checked. I've tried as much as possible to get this to vibrate with no luck. think it's toast?
does it give you the little bumb right when you turn it on?
take the battery out put it back in then hold the power button. it should give a vibrate then. if not, then yea you need a new vibrator.

thanks for the reply guys. Did a battery pull and still no luck. This is my wife's phone so its not rooted, and with all the games she plays I'll never hear stop hearing about the loss of progress. Installed a few different keyboards to see even if the haptic would fire up, no luck. She said it worked a few weeks ago, but noticed recently that it's gone. I went through ever setting I can find to try to test and and still not a shake.
Sounds like ur gonna have to use ur factory warranty.
Sent from my Nexus S
thats what I was thinking...ok my device is rooted so I can use titanium. Her device isn't. Is there any way to pull her game saves off the device without a root? If the nexus had oneclick root/unroot I'd rip that off no problem. The two rooting methods are quite different, and especially with this going back don't want anything to void the warranty.
Yea bro, sounds like your wife wore out her vibrator. You can root without unlocking the bootloader iirc then use titanium then unroot. Copy the backup to your PC then swap phones

you should be able to do a
Code:
adb pull /data/ /data/
and
Code:
adb pull /sdcard/ /sdcard/
that will copy her data partition where the games are and the sdcard partition to a folder wherever you ran the command. i haven't tried this but without root there isn't much you can mess up
adb is new to me. this unrooted crap annoys me, compared to using my cap. So firing up cmd, running those two commands with the device in (recovery menu?), should pull the data files? now when I get a new phone back, I will be rooting hers, would I drop the data files back in?

Yea pretty much. It doesn't have to be in recovery but if you are make sure to mount the partitions.

I actually have this problem. It happened in the first month I got the phone. Someone on the forums recommended that I do a factory reset. But because I didn't root and I don't want to reinstall everything, so I just use the nexus s without vibration. The vibrate will fix itself once a month for a couple days and then die again so I dunno what it is. Please let me know how you fix it. Thanks!

Restoring data from old nexus 7

I'm getting a replacement on my nexus 7, I was wondering how to restore what I had to my new replacement new. Such as game data and such. Is the only way if I rooted it?
Sent from my Nexus 7 using xda app-developers app
No worries buddy. It automatically restores through your email. When you start up the N7 enter in the same one you did with your previous Nexus. :thumbup:

Really? It'll remember where I left off on games too? I had a galaxy s2 and got a replacement, but lost all my data.
You will probably need to root and then use a backup program like titanium to backup from the old device, save the backup files to an external location, then restore to your new device. Of course rooting the new device too.

Titanium backup + a box or dropbox account will become your best friend.

eh. I have a mac with me though for the next month or so.. Won't rooting now, erase my data anyways?
I think it's an ICS thing. I'm not too sure about the data, but your apps are ok. I know they're backed up by Google. As for the data, I'm rooted. So...
What you can do is copy your data folder on your phone. You can actually see the file when you connect to your computer, and then just manually start copying your app data. LoL!! I can only imagine how impractical that is.

Begin tether via NFC?

So I have my nice new GN2 and my nice couple month old Nexus 7 both sporting awesome NFC tech, but what to do with it? My first though was pairing them via bt and using the lte from my Note 2 over my college's sad excuse for a wifi system to power my N7 during the day. Then I though maybe auto establishing a tablettalk connection as well. Does anyone know of a way to program the two devices to automatically connect in such a way?

I know it is possible. I was talking to someone who uses Tasker and an NFC tag to automatically tether his N7 to his phone, but I've never studied the recipe.
I'm not sure why the tag, but maybe so he doesn't have to remove the phone from his belt... it's attached to his holster case. He said he has another one attached to his car seatbelt clasp to set the phone into his driving mode.
Wish I could give you more details.
Yeah that's essentially what I want to accomplish, but I'm not crazy about sticking one of those tags to my device. I was just hoping there was a way (with or without root) to make it read the NFC connection as a tag and start the connection.

I suspect that you would be able to, since NFC handles touch and go and touch and connect. I think the problem for some people would be in how strong the NFC connection is on their phone (some of them are weak) and how close together you need to get the two unitsto trigger it, especially if they are both in thick cases.
Putting them back to back could be as much work as just creating a widget to trigger a Tasker recipe that would do the same thing.
I've been thinking about doing this, too, but haven't, so I might start playing with Tasker to see whether I can set it up.
I'm going to do the same. Let me know if you discover anything

How do they get these?

So, like a lot of people, I keep my passwords, I.e. bank account, credit card, etc... on my phone in Keeper. I installed androidlost to wipe my phone clean if I ever lose it or it gets stolen. But here's my question: if my phone gets stolen, chances are that the average Joe will find it and try to access the information on the device itself. So, how does the average person get around the keypad lock pin and access the password protected Keeper app? I know there are different ways to access info like through email. But I don't understand how they crack the N4.
I heard by laying it for some minutes in the freezer then they can read it out with a device.
And yes I'm serious .

That is how you do investigations in case you have to access an encrypted environment and you suppose the keys are stored in ram.
I do not know about keeper, but if you use Keepassdroid or similar apps just make sure they auto unmount after a short delay so people without che correct passphrase and encryption keys are unable to access thir content
Easy! Don't put important information in your phone. Put it in SD card; cut small part of your body; hide the SD card in it ?

Google Wallet Tap & Pay for Kit Kat: How to get it to work on N7!

Tap & Pay now works for Google Wallet for N7 Kit Kat.....IF you get the Nexus 5 version of Wallet!
Which you can find on Phandroid here
Instructions for n00bs: To install, download the .apk file at the webpage link above. MAKE SURE UNKNOWN SOURCES IS CHECKED IN YOUR SECURITY SETTINGS prior to download.
Then run the app and follow the directions in the app to setup Tap & Pay.
Make sure NFC is enabled and you have an internet connection when attempting payment (have the Wallet app showing when you are ready for payment.)
I just bought McDonald's with it....using their WiFi!
Sent from my Nexus 7 using XDA Premium HD app
thanks and yes, after installing that apk and setting it up, Wallet does now appear in tap & pay. I'll try it out. Thanks
I seem to remember a blog post and thread here how NFC could not work with Wallet on the new N7. I disagreed because the hardware is there and the security can be emulated in software. This workaround proves it. I'm going to McDonald's tonight .
Thanks

How can you make a payment without an Internet connection? :what: If that was the case, you make a payment offline, factory reset your tablet before it connects again. In theory, you won't get charged then, right?

No. Your device communicates your payment data via NFC. The element receiving that data actually executes the charge. Your device doesn't need to connect to the internet anymore than your credit cards need to connect to the internet.

...thought the app told me to have an internet connection. How else does the app retrieve your credit card info?
Granted, it COULD be stored directly in the app...but then that poses a security risk, I would think

Almost as risky as storing your credit card info on a plastic card in your billfold. Someone nips that and they have all they need to charge your account!
Sent from my Nexus 7 using Tapatalk 4
Guys you CAN pay without an internet connection. The Nexus 7 2013 works the same as the Nexus 5, using HCE instead of a secure element. I tried my N5 in airplane mode (with NFC switched back on) a couple days ago at CVS and it worked fine. As soon as I turned off airplane mode the transaction details downloaded.
Now while the transaction will work without internet Wallet now requires an internet connection to PIN unlock! So if there is no service in the store unlock it before going in. If you're feeling more daring you can use 1 day or no PIN timeout for wallet and not have to worry about internet connectivity.

One of the new features in KitKat is 'virtual smart cards' which allows them to take the credit card information and essentially create a virtual card that has the same content as your real card. It's protected the same way as your credit card does it. Tap and Pay is actually identical to "chip and pin" just done over NFC. So this duplicates the 'chip' part.
Any way to make this work outside the USA without any crazy hacks?
