Android 6 ROM suggestion? - Xperia Z3 Tablet Compact Q&A, Help & Troubleshooti

Hi.
I Just updated my Sony z3 tablet 4g version to Find out the sdcard as internal storage and restricted profile features are still missing.
Can anyone recommend a ROM with "restricted profile" and "sdcard as internal storage" and of cause 4G support?

You can add a guest profile?! You should be able to activate the sd card options with root or adb shell commands. Google it.

Sounds like i need to Look into The sdcard hacks.
Gust user is not what i want.
With a Restricted profile, you can share and controle what apps The profile can access.

the developments fora for this tablet on xda are virtually non existent. Maybe CM13?

[Q] Are apps always installed on the card?

I have just purchased an X10mini pro and have been playing around with it today. I was wondering if apps are always installed on the card, or are they sometimes installed on the phones memory? How do I change the default location of where apps are installed?
From what I gather Linux based distros are different in that they don't have a registry etc. When an app is run is it purely from the .apk location or are different files from the app copied to different locations when the app is installed?
They're pretty much universally installed to the phones memory though some software will install additional data to sd. It's an unfortunate limitation of Android 1.6, if an when we get 2.2 this'll change. On a rooted phone there should be ways around this but I haven't looked into it personally.
Ok thanks for clearing that up. I have now rooted my phone and see that the default location for apps is /system/app/. Does everything to do with the program just reside there (like a portable app) or are program libraries etc copied to other locations within the phone? For things like email programs where do they store the individual emails?
/system/app/ contains all the "system" applications (i.e. the stuff that's pre-installed on the phone) - you can't usually change these, unless you've got root access
/data/ is the user writeable section of the phone's memory - /data/app/ is where the stuff you install goes, along with the data any running apps save (unless they're specifically programmed to save stuff to the sd card instead)
So the email program at /system/app/ Email.apk where does that store it's emails? Does it store the emails in /data/ or somewhere else? What about browser cache, where is that stored?
Does anyone know where I can download a guide on file structure to try and understand what exactly does what?

Why Does Reading the SD Card Not Require Permission

Like the title says why are apps allowed to read the contents of files on the SD card without asking permission? Apps have to ask to read SMS, Calendar, and everything else. It seems like a huge security hole to me. Thoughts?
Anybody? No thoughts or reasons at all?
I believe that there's nothing secure that can be read from the SD card without explicit permissions. You need WRITE_SECURE_SETTINGS to read secure settings... all your calendar data and so forth are either outside the handset or stored securely... etc.
However, I'm not an Android developer --
SD card functions as a storage device. So writing files on it should not require permissions. Only access to certain files/apps have to require permissions.
Have you tried fixing permissions? Don't know if it will work but its worth a try I guess.
To me it just seems like a security risk but then I guess Windows software allows the same thing and nothing can stop from reading contents of the hard drive. Still seems unsecure though that any platform, mobile or non-mobile would allow this behavior.

[Q] Change Default USB mode

I'm posting here as the forum specific to my device doesn't seem to have enough exposure and I don't think the solution I'm seeking is device specific as such. I had posted this without any replies.
I would like to know where the configuration for the default USB connection mode is stored. Ever since I started using an SD card, connecting the phone to a PC would always start mass storage mode, making many apps unusable.
Running a Custom ROM variation of the stock Huawei P7 -L10 on android 4.4.2 (EMUI 2.3).
Phone is rooted.
Many thanks!

Problem with phone storage access after recovery reinstall

My phone is a (cheap) Wiko Ozzy. I know it's not the greatest machine ever but it does the job for my mobile needs (being able to quick search the internet everywhere and communications), it was only 80€ new and it comes with no bloatware but google's. Also to root it a simple framaroot run does the job.
I have the phone customized alot, many xposed tweaks, automate, nova laucher, gravity box. The rom is the stock 4.2.2
One day I was messing up with android tweaker 2 and changed the dalvik heap size. When I reboot it the did not boot... It had that vibration key feedback problem. lol....
I went into recovery mode and made a backup... Yes, I did not had one and made it after the boot problem.
For my luck Wiko has a website with the roms they put on phones for download. With a simple program you can reinstall the rom very easily. I did it and my phone booted. I then tried to restore the backup I had previously done and for my surprise it boot with all my customizations but root access and busybox that I had to reinstall.
So what is the problem you ask?
Well I lost access to the phone storage and now It says Im out of space when I try to install apps
I used to have SDcard, Internal Storage and Phone Storage.
And I used to have the option to default install on sdcard and phone storage. The phone storage option disappeared but on the bottom of the page there is a mount option for it that just wont work.
I also tried to access it on windows and even after formatting the phone storage drive (windows was prompting for it and since the phone worked all fine without access to it I did it) the problem persisted...
Can you help me please?
I wanted to make the apps install on phone storage without having to make a real factory reset so I dont end without all my tweaks...
No one have any ideas?
I dont know what more can I add...
The phone is working fine... the only thing missing is one of the three partitions I had before the reinstall...
The weirdest to me is that in the storage settings I have the option to mount the "Phone Storage" but it fails.
I click it and the bars for type of files appears and disappears a few seconds later with the notification: you can safely remove phone storage....
Now I cant even install Adobe Air to try .swf viewer because it says it is out of space... It's like it ignores the sdcard default install option (the only one I have now and that is selected).

[HowTo] Fix songs on external SD-Card lost after reboot on Samsung (Galaxy) devices

Affected devices: (Samsung Galaxy, devices without adoptable storage)
Operating System: Android
No root required, KNOX Bit untouched
Fix songs on external SD-Card lost after reboot on Samsung (Galaxy) devices and similar
When you make use of an SD-Card for more space for songs and reboot your Samsung or similar Android device, the Spotify App starts before the SD-Card is ready for use. This breaks the downloaded files and can only be fixed by a complete reinstall and redownload of all files. The storage cannot be switched back. To prevent this issue, here is the solution.
Prepare your device
Uninstall and reinstall spotify
Enable developer mode
as described here by Samsung their self
Enable Apps on external storage
In Developer Options in Android Settings turn on "Force allow apps on external" / "Externe Speichernutzung von Apps erlauben". This the 2nd last setting in developer options
Go to Settings - Apps - Spotify - Storage - Change / Ändern and move it to external storage
Use it
Open your Spotify App, download some playlists, wait for the download to finish, reboot your phone and see yourself. Do not forget to set music quality to very high before starting downloading all your playlists!
Background
The Spotify App starts on boot (phone restart) and is lacking an option to delay the app start. Maybe this is even impossible on android and not spotify's fault. Samsung does not offer the adoptable storage option without above steps. By performing above steps you make sure that the Spotify App is started after the SD-Card has been mounted and is ready for use. Issue workarounded.
