has anyone done this yet? I noticed it in the settings, but it said it can take up to 1 hour... just wondered if it was worth while.
if you have done it, does it slow anything down, and how long did it take you to run?

I tried but it appears to not work. You have to be plugged in and fully charged (seems to work from 90% ish), and you have to have unlock PIN set. But once you have selected and confirmed encryption, the screen blanks except for a green line drawing of an Android logo, and then after a minute or so the screen blanks out and then you wait...and wait....and wait...and wait. I gave up after 4 hours.
If at any point you switch screen on, you get the PIN prompt: enter PIN, and you're presented with the blank screen with green line diagram of android logo. I've left it like this for several hours. In the end I reset, and got my device back - but still unencrypted. I've also tried without ever trying to log in until at least 4 hours have elapsed, in case the login attempt disturbed the encryption.
I have logged a defect with Asus for this and a couple of other things, and this morning got a response back saying that "We're still looking into this", which seems to suggest that they agree it is a problem.
Cool in gonna try now, at 95percent battery.

I'm wondering how the encryption is handled, is it software or hardware enabled. I have seen with PC's that use software encryption that there is a performance hit and if the encryption is handled by hardware, like a hardware enabled HDD encryption, there is little to no performance hit. The PC I tested the software encryption on took forever to boot vs the hardware enabled one.

You must have used some strange encryption application or had an old computer.
Try truecrypt - on modern (2 core) computer there is practically no performance hit whatsoever (decrypting and even encrypting on the fly is faster than hard drives - on SSD it could be too slow though). The same goes for standard encryption used by Ubuntu (it's very probable that Android tablets use the same method).
Truecrypt (and probably most other full-disk encryptions too) work like that:
- all the data on hard drive is encrypted (edit: it's encrypted all the time, never, ever is decrypted data written to disk),
- when system reads data - it's decrypted before being send to applications,
- when system writes data - it's encrypted before it's saved to the disk.
Also - Tegra2 should have a part handling encryption and decryption so it could be at least partially hardware encryption.
Your right, it has been a while since I have used encryption due to a bad experience early on. I'll give Truecyrpt a try. The software I used before was Safeguard Easy.

I left mine overnight, and it still was not encrypted. I had even done a factory reset beforehand to minimize the amount of data to encrypt.
I'm pretty sure this doesn't work. I'll post as soon as I get a reply from Asus.
It did not work, maybe this feature isn't ready yet?
Sent from my Transformer TF101 using Tapatalk
As a feature, it's not ready for prime time. I have it working on the xoom, but every reset it erases my timezone and sets it to GMT. Also, it uses the same PIN as your lock screen, so if you have a numeric pin for easy access, anyone who sees it now knows your encryption password as well. It really should be two different passwords. I intend this weekend to reset my machine and remove the encryption, because it doesn't serve the purpose it was supposed to serve.
Bump. Any info from Asus? I started it at ~7pm. It's midnight, and on the last few power-ups I get nothing except the green android logo after I enter the PIN. So it seems it's still not doing anything? Gonna reset now I guess.
Same problem here with a Transformer TF-101 Build number HRI66.TW_epad-8.2.3.8-20110423
See nothing but a android robot after enter the PIN. 7 hrs later I manually shutdown the machine.
Same here on the Modaco ROM.
Left it on the android pic for 9 hours... it didn't lock the screen or anything, and at the end, the accelerometer still worked when I rotated the screen, but I had to power off and on to get it back.
What does the encryption do, anyway? Does it stop you being able to load files on from the PC? Does it ask for the password when you plug it into the PC?
So no one has been able to get encryption working? I was just going to test this out and saw this thread. Thanks.
I've seen someone talking about some minor issues when running with encryption, so someone got it working.
That MIGHT have been on xoom, but I think it was the transformer.
Just thought I would share my experience with the encryption feature in Honeycomb since some people can't get it working:
At first I couldn't get it working like some people on this thread, I too was stuck on the green wireframe Android for hours on end until I discovered I could still exit back to the homescreen by pressing the home key on the keyboard dock. This happened on both the stock Asus 3.1 ROM and v1.4 of the PRIME! ROM (installed via nvflash).
I then updated recently to v1.5 of PRIME! via CWM and I can report that I was able to encrypt my Transformer after this update. It displayed the green Android wireframe logo for a few seconds, then rebooted and went into the encryption progress page. I had not really done much with the ROM other than change a few small settings and add my Google account, so the encryption was complete in less than an hour. I think the 'hour or more' estimate Google gives within the encryption description text is probably more accurate if you've installed a few more apps afterwards, but of course your timing will vary.
Furthermore I think that the encryption is likely only partial, because I was then able to flash one of the zip files from this thread via CWM without any issues or prompts. Otherwise I'm sure it would've thrown some kind of error such as not being able to mount the system partition or something of that ilk.
Finally (lol ) I also found this page on the Android source website outlining the details of the encyption implementation in Android Honeycomb for anyone interested. There is a mention somewhere of the 128-bit flavour of the AES algorithm being used to encrypt the master key.
Hope this helps anyone trying to get encryption working on their Transformer .
yet another absolutely useless feature, besides bricking the thing for whoever tries to steal it. keeps your data safe.. even from yourself.
i noticed a problem when inserting a microsd (into the pad itself) that it would not be able to boot as long as this is inserted. i am guessing this is because it tries to decrypt the microsd (that is not encrypted) and therefore is stuck in boot.
This is another aspect one should expect if this was a pre-release software. I am extremely disappointed with this product so far, mostly because of the software. most of (not any of the cameras) the hardware (including the keyboard) is pretty good
I did it 2 days ago, and it worked flawless. It tooks about an hour. I use it since and I have no problems at all.
The only thing is that I have to insert the SD card again each time I power on the transformer. Any idea how to change rhat?

You likely have ASUS to blame for this, as my understanding is that the Thinkpad tablet deals properly (from the spec anyway) with SD cards attached to the device even to the point it can additionally encrypt them. Again we are all early adopters, Honeycomb was sort of an experiment for Google, and Ice Cream Sandwich is the real next version of the andoid platform.
And encryption is hardly a useless feature, it means Google is finally trying to consider enterprise usage of their products which is very important to the further growth of the platform.
Hi,
i noticed months ago the following on my IDEOS X5 (german) concerning bad battery life. It could be the reason why there are so many different reports regarding bettery lifetime of the U8800.
First - why did I start to investigate: because the phone sucked about 5-10% per hour while not beeing used / lying on my desk, so after max 20 hours the battery was empty. But this did/does not always happen....
What I did: it took some time to get used to android (its my first droid) and learn how to troubleshoot. A month after I got this phone I learned that the GSM-code *#*#4636#*#* will show you very useful information concenring battery/phone usage. I started to play around with the phone (factory reset, install/remove apps, enable/disable different options like 2G/3G/WLAN etc...) always keeping an eye on the 4636-infos.
Result: When I use WLAN the phone simetimes enters an "state" when it never again enters "sleep state" and the battery gets sucked as stated above. I switched off WLAN for a week and this did not occur while standby time increased to 48 hours and 4636 stated an "phone awake" percentage of below 20% (normal usage). Once I reenabled WLAN again it took about an day of WLAN usage to reproduce the bug and "phone awake" time increased to 100% while standby time decreased to below 20 hours. ONLY rebooting the device recovers from this "state". I further noticed that this does not happen if just WLAN is available but no 2G/3G (phone had no SIM). My conclusion is, that the
"You May Be Charged"-Popup is the culprit. It does lock the phone to this "state" for some reason, mybe when the WLAN connection is dropped while the phone is not used (traveling). Can someone reproduce this on his phone (maybe not german)?
Resolution: IMHO none. I send the device twice to reseller for service. First time the complete mainboard was changed without success regarding the battery drain. Second time nothing was done - they just returned the device to me.
Thanks.
This is a known problem, that already has a thread...
http://forum.xda-developers.com/showthread.php?t=1043760
This is affecting ALL Froyo Roms, if you want battery life, install Oxygen or CM7...which are based on Gingerbread.
There is no point in discussing this issue anymore, this is a very well known problem and Huawei doesn't care.
Sending the phone back to manufacturer won't help at all.
Thank you for the hint - it realy looks like the same issue. Knowing more about the nature of this issue could give people not willing to install custom roms a possible solution. Can someone move this thread over to that one?

I hope some more bugs are straightened out like headphones and internal mic at the same time. Headset button to work. Battery time!
none of my android phones could use the phone's mic when headphones were plugged in
I saw a solution for the mic-with-headphones-problem a few days ago, either here or at modaco (do not know if it is confirmed working though).
fajabird, I know that you want this to work with the ROMs provided by Huawei. Huawei obviously does not care too much about providing the community with updates (they do not even have gingerbread-support by now). This is the downside of this low priced phone.
Let me just say this: It took me about one hour to understand the ultimate-guide at modaco. It took me another hour to decide which ROM I want to use. If anything goes wrong at the installation I can easily start over again. Now I have a fully working phone with Android 2.3.5 with a battery that lasts at least 2 days, sometimes 3(if I do not play any games within that time). Of course I understand that you are probably very pissed at Huawei for providing a ROM with a bug that serious.
if you find that fix again, let us know where to look

Hi, thank you for sharing your experience with me. I always wanted to update to some custom roms but the time I started investigating this issue there was no stable one out there. On the other hand I thought there might be a dev interessted in more details regarding this issue helping him to sort out this nasty bug for whatever reason.
Can someone tell me, if his U8800 also has the ambient light sensor but like mine does: it won't reduce the brightness, just increase works. Thanks.

Mine reduces brightness but does it quite weird sometimes like adjusting several times without the light around me changing...
Mine always adjusts it way too low. If I am inside the brightness is always on minimum. I use the power-widget on the homescreen. I only change it at night, it is on max. for the whole day (the max. brightness is still kinda low, especially if it's sunny).

Hey there friend, I've detailed much of this and been through a lot of troubleshooting. It did not appear to be the "You may be charged" popup as I disabled that whenever I changed ROMs. I never did get a solution for any of the Huawei ROMs, it just seemed like bad code as Dzo pointed out with the WiFi driver.
A very simple solution for me was installing one of the 2.3 ROMs, they are quite stable at the moment, especially Oxygen (although I use MIUI). You will find much better battery life with these.
Best of luck,
Ryan
My stock rom 2.2.1 Shows Android System 97% battery usage and battery drains 50% in 19minutes! With wi-fi, 3g, Bluetooth, everything is off and even i do not use it.
Flash latest official 2.2.2, wait for official 2.3, flash the custom 2.2.2 rom void or flash a custom 2.3 rom. I would recommend flashing the latest 138 or 162 to get the latest modem baseband or manually install the AMSS.bin.

Hi,
I am thinking about encrypting my Nexus 4. I am already using encryption on all my computers but I never tried it on my smartphone, so there are three questions I hope you will answer:
1)
How is battery life affected? Well, fortunately the battery of the Nexus 4 is quite good and I hope encryption won't waste too much.
2)
How is speed affected? My Desktop CPU has AES-NI and there's a SSD, so you don't even recognize system encryption. How is it doing on the Nexus 4? I'm just doing the usual smartphone stuff, means E-Mail, messaging, phoning, checking News &Weather and sometimes playing Doodle Jump. My research on the Internet about encryption performance on Android didn't bring up things I can really rely on so I hope someone here can tell me his experiences.
3)
Which algorithm is used exactly? I know it's dm_crypt and I'm using it on my other computers, too, but on my PC I can choose which algorithm I want and on Android it's given as far as I know.
Regards,
becha
You can't use patter lock to unlock your screen, which is a pian for me right now.

Sent from my Nexus 4 using Tapatalk 4 Beta
1) I doesn't notice any real impact on battery life. Used the N4 several months before encrypting it.
2) Booting the phone is slowed down, and not only because you have to enter the key for accessing the encrypted drive. But opening apps and doing backup, etc. isn't slowed down. I guess I wouldn't even notice an encrypted devices and so did no one until now, while using my phone.
I was also doubtful before, because in my experience, on a laptop back in the days (5 years ago), the battery drain and performance impact was just to big. But on the other side, I do a lot more disk based tasks on my laptop, than I do on my phone.
in short, after I lost my last phone, I really wanted to give it a try and I didn't regret it until now.
Hoping to hear good answers to question 3.
@HB_Mosh
Well, that's not too bad for me because I don't use Unlock Patterns.
@Vanhoud @memleak
Thanks for sharing your experiences, I'll give encryption a shot.

Yesterday I encrypted my Nexus 4, it took around an half an hour. Until now (well, one day...) I didn't discover any problems apart from the fact, that my Nexus 4 did a simple restart for the first time when trying to encrypt it. Everything went fine when trying the second time. The phone itself runs fluent, so up to now I didn't see any performance problems.
Now I can't backup my ROM - any suggestions? Perhaps Recovery can mount to an external USB storage or something? What a pain! You can't un-encrypt either, and there's no way to mount encrypted storage in Recovery I wanted to backup before installing privacy protection in case it borked my phone.
Another encryption question...
Don't mean to hijack this thread, but can anyone tell me if OTA updates will still work on a stock, unrooted N4 that's been encrypted?
Can't find a definitive answer - some have had success on other devices and others haven't.
I don't see why turning on stock encryption on a stock unmodified device would make any difference?

I wasn't sure why / if this would make a difference either but as I said, I can't find a definitive answer. Some people say that you need to factory reset in order to remove the encryption before you can apply an OTA update, but others say different.
I'd be interested to know if the OTA would work after simply asking you for your encryption PIN on reboot, or if the encryption would prevent the OTA being applied because of the encrypted storage. Does anyone have any experience of this?

You have to use TWRP Recovery, which is able to mount your encrypted internal storage.
No way.. I thought I'd tried every option I could think of in TWRP but I'll take a closer look.
Sent from my Nexus 4 using Tapatalk 2
If you start TWRP, it should automatically ask for your passphrase to read the encrypted internal storage. Latest version of TWRP works for me, older ones had bugs regarding to encrypted devices.
dunno why this keeps happening im on the stock 5.1.1 and after a few months of use the device becomes very laggy and slow then after a factory reset its fast again. anyone know why this happens? i usually leave 3gigs of free space on it at all times too.
Unfortunately it's a normal behaviour for our Nexus 7
If you are rooted, you can try to run FsTrim regularly which improves the situation a bit. You also should try to keep >= 4GB of memory free, this even helps.
Otherwise you will need to deal with it is some way.
hmm more than 4gb free, ok will try and clear up more space, iv unlocked the bootloader so can root easily too.
also read up a bit on file system journalling, any more information on this?
has anyone used this mod: http://forum.xda-developers.com/showthread.php?t=2280496
also shouldnt the trim command be running automatically on its own?
got more info on this now, i think i will go the method of rooting first and use manual trimming method with an app like this:
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
reviews show its full of nexus 7 users lol.
so i rooted it last night and ran fstrim, it trimmed 5gigs. device is now back to its usual speed that a factory reset normally gives. issue resolved for now....
Hello,
I have a stock Moto X force for about 20 months.
I've been suffering from lagging lately (sometimes it takes a few seconds when trying to switch between apps or the keyboard becomes unresponsive). I think it got worse after the 7.0 update.
I've downloaded an app for system monitoring and I've noticed that at times of lag the internal disk activity is maxed (Read & Write are 100% (not sure exactly what that means)) (Can't add attachments). But, cpu performance and ram usage seems fine. I assume some app is causing this but have no suspects at the moment. How should I continue my debug from here ?
Thanks
Hello Juvesss,
Exactly the same phone with the same problem since one week ago... If you solved it please explain me, this is a pain!
No OS upgrade was involved in my case, I have Nougat since a long ago.
Cache wipe did not help. Limiting background processes to 3 helped just a little (developer menu).

I've been noticing this problem too.
Not sure what the cause is.
I've factory reset and that seems to fix the problem for awhile, but it seems to come back over time.
Something in the stock rom must be cluttering the phone.
Dear roweboat56,
It happened to me after 12 months of having it, so for my experience it is not so frequent. How often happened it to you? (To understand better how long will I "enjoy" the factory reset solution...)
Move to a custom rom!
I faced that issue too! The last update was buggy maybe..and the moto services and rest apps by moto are eating a lot of ram and using a good amount of I/O
.
Try this rom by me (on the latest 7.1.2 build with 5th February 2018 security patch)

Hm I noticed after maybe 2 months of use or so?
Im on Latest Stock FW Android N ,using the device since 8months and not find any lag, in my case it lacks a bit when heated a lot.
I didnt disable any of the Moto Services though.
Try using Greenify if it solves the issue. I will not unlock my phone till it gets 14-15month old and see whether the same happens to me
It is strange... In my case the phenomenon suddenly disappeared some weeks ago, so I think some system update messed it all and later another update solved it. I have the impression it was a system problem and not a particular app, because I tried to uninstall the more suspicious apps without appreciating any change.
