[G4 Q&A, Help & Troubleshooting] xdaparanoia:
What is the current state of Android 6+ encryption on mobile devices? How secure/useful is it really? And how does it work in practice?

1. When I have first booted the device, did Android 6 automatically encrypt the internal drive with my Lockscreen password?

2. What was being encrypted - the full internal SD or just (which) parts?

3. Will the internal (or external, if separately selected) SD card continuously encrypt new /added data?

4. When I change my Locksreen password, will all SD cards be re-encrypted with the new password or do I have to unencrypt(external) and wipe all and re-install (internal) SD cards?

5. How save are the data on a running vs. a shut down device compared to a True-/Veracrypt encrypted PC, assuming same passphrase strength (20+ characters)?

6. What are the latest known (hardware/processor-, software related) vulnerabilities of Android 6+ and Qualcomm and Exynos processors (KeyMaster Key Blob extraction / Trustzone problems etc.) in terms of encryption? Is it still the case that e.g. Samsung (with S9) has no (under Android possible) revocation of vulnerable old TEE trustlets implemented, so that attackers could just flash a custom firmware/Android build/old trustlet and extract the Key Blob? Is such a system still decryptable when the Lockscreen password /passphrase is very strong (20+ characters)?

7. Are there 3rd party full disc encryption apps available like Truescrypt without vulnerabilities?

8. Are there 3rd party file/folder encryption apps available (for rooted or unrooted devices) without vulnerabilities and can I encrypt a complete external SD card with or all e-mails, contact data and calendar items on the phone with such a software easily /automatically, especially if system apps (calendar, contacts..) can’t be moved to the external SD?

Thanks for all comments!

Hi all!

Is there any method to get the longpress back 2 kill application function on Oreo???????:confused:
[Lenovo P2 Questions & Answers] LesMcQueen:
Hi all.

Had a bit of an accident with mine a couple of months ago where the phone had a brief dunk in the toilet. :eek:

I opened it up and checked that there was no moisture inside, and it powered up fine after 24 hours in a dry place.

I though I'd gotten away with it, but I now find that it doesn't show up as a connected device via MTP/ADB/Fastboot.

What's strange is that if I try to set USB connectivity type via developer options (MTP/PTP/Charge only etc.) it doesn't seem to allow me to set the mode. Feels like a ROM issue :-/

Any ideas? I can't be 100% certain that it's down to water damage as I didn't test connectivity straight away. It seems a bit far-fetched that water damage could have knocked out just connectivity, as everything else works fine.

Thanks in advance.
[Lenovo P2 Questions & Answers] sm00th4f3:
I had the same issue.

Before we try to wipe your phone to flash stock firmware, let's try some driver tweaking.

Search on Google for Qualcomm drivers. Any are fine.

Install them and try to connect again.

If that fails, be prepared to reset your phone.

Copy all your important files to your pc!

Shutdown the phone, hold volume + and - as well as power key until the logo shows up, you should now see .

Otherwise I found a video of YouTube

[youtube]0YZVo1PkGRU[/youtube]

In there select wipe user data...good luck
[Lenovo P2 Questions & Answers] LesMcQueen:
Hi sm00th4f3.

Thanks for your response.

Things I've already tried are........

o Connecting the phone to multiple PCs. None 'chime' to say that a device is connected.

o Factory defaulted/wiped from recovery

o Tried reflashing the S251 OTA update file from recovery as update.zip

o Cleaned the contacts on the USB socket

o Tried different drivers

As fastboot or ADB won't see the device, I'm not able to push the image.

Is there a way of doing a full stock rom flash from the SD card via stock recovery? If so, does anyone know where to get a flashable ROM?

Thanks guys.
[Lenovo P2 Questions & Answers] sm00th4f3:
Somewhere on the custom ROMs ,recovery etc section there exists a thread with flashable zips for the stock recovery...there aren't many so you should find it pretty quickly. In recovery use sd card package update or some thing similar in name.

Try that. The process will take a while.

On another note, your connectors seem to be done. You might need new ones, but as long as it charges, that should be fine.

You can use AirDroid for file management like copying audio, pictures whatever you like..etc
[Lenovo P2 Questions & Answers] LesMcQueen:
Hi all.

Thanks to anyone that looked in.

I managed to fix the issue, but it does appear that the problem was down to water damage.

I purchased a faulty P2 from ebay for spares.

Most faulty P2s were selling for £60+ as the screens were intact, but I found one with a smashed screen and won it for just over £10.

I swapped the lower board over to my phone (micro board with USB connector and speaker attached) and was immediately able to connect via Fastboot/MTP etc.

Well happy :)

I've now got official Lineage 14.1 on it.

EDIT: Oh yes, and now I've got a spare battery, and a 32GB microsd card that was left in the phone ;)
[HTC U Ultra Questions & Answers] Willan Zar:
Hi guys,

I bought a htc u ultra when I was living in Australia but early this year I moved to Sweden. Now my issue is that android 8 is out, but my phone can't find the ota update. How come? I have received other ota updates in Sweden but the oreo update will not be found. Is there a way I can get it pushed to the phone?

I've contacted htc, but they are bloody useless, they just tell me to contact Google which I can't even find a email address or anything for help.

Hoping some bright spark can help me.
[HTC U Ultra Questions & Answers] QDT:
No help for you. Your device CID is for Australia and for this region the update is not yet released.
[HTC U Ultra Questions & Answers] Willan Zar:
So why couldn't the retard at htc just tell me that? I swear they have the worst customer support ever. Told them this is my last htc mobile
[HTC U Ultra Questions & Answers] QDT:
Like they care about you. Statistically you got yourself a budget phone that is pretending to be of premium level. That means your next purchase will be in 2-3 years.

I'm blunt but that is life. I made my decision of getting this piece knowing there is almost no community and is already forgotten by manufacturer. It was cheap so I didn't care if I brick it by customizing. It the moment I'm working on a dirty port of LineageOS to it so I won't rely on HTC (unless I hit the kernel issues). If succeed I might consider sharing it bit wider.

But anyway - don't get too emotional. There is literally nothing that great with Oreo to get angry over. You could actually flash the LeDroid 2.1. It has been reported to work with Nougat backbone. So you get Oreo with Nougat Radio and Kernel. But then really say bye to HTC direct updates if they ever happen.

Oreo 8.0 Released in Australia!

HTC contacted me via social media to inform me that as of today, May 31st, the Android 8.0 Oreo update is available for HTC U Ultra phones purchased outright in Australia! Mine updated to 2.21.710.3 today. :)
[HTC U Ultra Questions & Answers] QDT:
Then I suggest you to make TWRP copy of the system partition just after upgrade and share it with [MENTION=398245]LeeDroid[/MENTION] so he could update his custom ROM also for Australia.
[HTC U Ultra Questions & Answers] lachlanwilliam:
I just got the upgrade too - I can't believe how laggy it is now.

Haven't performed a reset yet, hoping it will clear up after a few days.

Extremely disappointed...

Battery seems *slightly* better however!
[HTC U Ultra Questions & Answers] adamszostek:
I did a factory reset and first few weeks was ok - much better than on nugat. But now after two month of use I see that slowdowns and lags are more common. Especially when the phone gest worm it can literatury stars to crawl.

Actually I'm thinking to upgrade to U11
[HTC U Ultra Questions & Answers] lachlanwilliam:
Update: the battery is absolutely shocking now.

Tested it yesterday, left on a table after charging all night to 100%

Screen turned on twice throughout the day and after 6 hours and 25 minutes it's at 1% and the power off warning is shown.

Spoke to HTC support who have ignored my last 3 messages so won't be getting a HTC phone again.

Absolutely ridiculous.

Was a fantastic phone after first purchasing it (first 3 months) but now after 6 months - shocking
[HTC U Ultra Questions & Answers] ChavezD:
Did you try a factory reset?

Or check e.g. gsam batters stats from play store and have a look at doze/active stats or warlocks and so on, mostly there is an app (or system) running in background and consuming battery
[HTC U Ultra Questions & Answers] lachlanwilliam:
Yep,

it's been reset 3 times so far.

I did have a look at gsam, what a great application - thanks!

Have a bunch of wakelocks - mainly around Google Fitness (I definitely don't use it) and a bunch of wifi 'wlan rx wakelock' too so currently troubleshooting that,

One thing I did notice however - on attempting to clear the cache partition, I have some notes in the 'recovery mode' screen

"handle_cota_install install cwpkg to /cache/cota/cwpkg.zip

handle_cota_install install cwprop to /cache/cota/cw.prop

E: cant open /sys/class/power_supply/battery/capacity

handle_cota_install: Cant mount /sdcard"

That battery one doesn't sound very promising.... perhaps that is one of the reasons why? The phone doesn't know what size battery is installed because it can't read the capacity configuration file?

I'm not rooted so I can't check to see if it's present myself

zzz

HTC should fix this sort of thing - i'm not sending it away to get looked at/reflashed for 3 weeks

[Android Q&A, Help & Troubleshooting] Msprg:
Hi,

I have Samsung galaxy s4 mini (gt-i9195) with broken screen(+touch not work), and i want to reuse it. The problem was, that i could not get even into the shell, because was usb debbugging disabled. After some time trying (feels like blind :D ) i managed to get to the shell trough recovery. Now, I do not know if I can do that again, but i used following commands in recovery to access the shell in "normal operation" (not recovery, simple ordinary usb debbugging with system on-line). :

echo "persist.service.adb.enable=1" >>/system/build.prop

echo "persist.service.debuggable=1" >>/system/build.prop

echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"

ro.adb.secure=0

reboot﻿ (btw, reboot did nothing)

But, it does not work... i am worried a bit. phone boots up fine, when i connect the phone to the computer phone play charging sound, bottom keys for back and menu is lighting up properly, and computer recognize phone correctly. (Also, phone may have password, pin or gesture lock, can that affect it? )

By "ADB not working" i mean: if i enter "adb devices" command to cmd, it returns only blank line. Or sometimes blank line with "-" char on the beggining (only - not the quotes :) )

As the result, i expect adb shell access, and ability using this tool: https://xdaforums.com/showthread.php?t=2786395

p.s. notice that quote on the third (last echo) shell command line at the end, wich i entered. May be a typo, but not my fault, take look at the link above, copy-pasted from there.

Thank you for your answers and suggestions.

[OnePlus 5T  Questions & Answers] xgerryx:
OOS Camera apparently can never work right on custom ROMs, which annoys a lot of us. Basically the only reason why I'm stuck on OOS forever. You can use the Google Camera but there are a million versions and most of them have problems with Slow motion, front portrait, or some other thing. It works, but it's not perfect. It also doesn't flip the selfies like the stock camera does, which actually bothers me. So you either need to edit it before sending or just deal with it.

[Galaxy Note 4 Q&A, Help & Troubleshooting] mihaidragos:
Hello, I am having some battery issues with my Galaxy Note 4 ( SM-N910F ), first of all battery drains very fast. And when it goes under 60% opening a more demanding app like Snapchat or Mortal Kombat X the phone just reboots and then boots up i enter my pin and after a few seconds it shuts down again reboot and so on.. until it doesn't even get to the main screen. Only way to fix this so far i found was to plug it in. And if i don't open a more demanding app and just do usual stuff send messages or listen to music, it gets to ~35% and then it shuts down(not reboot). I turn it on aand it's 15% then i barely get 5 minutes out of. But i have two batteries for this phone, and both have the same behavior only at different percentages and the other one drains even faster at around 1% per minute. Question is: could there be a problem with the phone or just the batteries are almost out of juice? The voltage is under 3.6 most of the times when not charging and when charging it barely goes up to 4.0, that is under 80% when over 80% i get 4.4 when charging and 3.7/3.8 when not .

Hello all, long time member but never really had a reason to post.

I just received my oneplus6, I wanted IOS style emojis (ridiculous I know... lol) So I unlocked bootloader, flashed the temporary TWRP release and flashed MAGISK.

When I booted my phone the error "There's an internal problem with your device contact your device manufacturer" comes up. Unfortunately I took my nandroid backup AFTER installing MAGISK.

I have no wifi at all, I can't use wifi hotspot either, but cellular works. I wanted to flash back to stock recovery but it seems oneplus hasn't released it. I have tried removing magisk and rebooting (via the magisk app) but then the device wont boot.

I canno't flash a stock copy of OxygenOS as it seems it can only be flashed with stock oxygen oneplus6 recovery (which I cannot get access to.) TWRP simply fails to flash it.

Recently in an attempt to solve my issue I formatted the memory, magisk has gone from my app drawer, but the effects it had are still there (I still have IOS emojis) Now apps wont login (snapchat for example says there is a temporary error) Facebook managed to login after a few reboots, I cannot stream video at all. And as I have formatted memory the original nandroid backup (after magisk flash where apps would login but still gives the internal error message and no wifi) is gone.

I really just want to get the device back to a stable operation, if anyone knows what I should do next or somehow has access to stock oneplus6 recovery, please let me know! Thankyou in advance for all help.

Q: After flashing Magisk, my device will show a scary popup saying "There's an internal problem with your device. Contact your manufacturer for details"

A: This is caused by dtbo image patched to remove AVB 2.0 of the vendor partition. This is required for allowing you to mount vendor to rw and make modifications

If you never plan to modify the vendor partition, in Magisk Manager, "Uninstall > Restore Images" to restore the images, check "Preserve AVB 2.0/dm-verity" box in Advanced Settings, then reinstall Magisk via the app.

[Asus ZenFone 3 Deluxe Questions & Answers] pegasusaile:
Hello,

I don't receive any more OTA updates on my Zenfone 3 Deluxe ZS570KL Pro (Z016D) whereas before it was able to download them and to install them.

I contacted the support of Asus compared to this problem. The support, after investigation, indicated to me that it had undergone a modification either by the use of the official tool UnlockTool or by the installation of a bad version of firmware. However, I indicated to them that this telephone was new and no modification had undergone. It managed to receive OTA updates.

As it cannot any more download and install OTA updates, it was advised to me to carry out the updates manually.

I carried out manual updates WW-5.15.44.2588 and WW-5.17.44.68 with success. However, when I wish to carry out update WW-15.0210.1804.47, this one fails and doesn't install.

Could you indicate a procedure to me to install this update and to explain me the reasons for which it doesn't install ?

Moreover, there is it a method to lock the bootloader again on this phone if it was modified as the support of ASUS indicates it?

Anyone else has this problem and found a solution ?

Thanks a lot.
