[Xperia Z3v General] Jurassic Pork Fried Rice:
The multi user and guest account feature is not available on either of the two recent releases of Lollipop for the Z3v. I did some research and it appears this is the case, not only on other Verizon handsets like the Droid Turbo and the Galaxy S5 / S6, but a few other non-VZW devices as well. I'm not sure why it was removed but apparently it's just

hidden

. It can be enabled and I followed the instructions for doing this for the various other devices and can report that it works for our Z3v (see attached screenshots).

I've kind of cleaned up the instructions and put them below. Usual disclaimer - I'm not responsible for anything that may happen to you or your cat if you choose to do the following. You DO need root access to edit and write to the system file.

** To be safe, please make a backup of your phone and/or a copy of the build.prop file that you are going to edit.

Get ES File Explorer. Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)

With ES File Explorer, go to device/system/ and find the file: build.prop

Choose to edit it with ES Note Editor.

Scroll to the end of the file and type in the following:

fw.max_users=5

fw.show_multiuserui=1

Save the file.

I'm not sure if the next step is required but it was in half the instructions I saw, and I did it myself: Click and hold the file, go to Properties, and then change the permissions to Read, Write & Execute. [all three]

Reboot your phone.

When you're up and running, access multi user mode by pulling down your notification shade and then clicking on your user icon at the top right corner.

Notes so far:

A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.

Therefore, an app such as Movie Creator can and will create a "highlight" movie that is composed from photos that are saved on the external SD Card. Just keep this in mind as far as privacy.

There is a per user option that lets you decide whether or not the additional users can use the phone and access the text messages. If you disable this ability, while they cannot open the phone app to make a call, the CAN receive an incoming call.

You can find out more about the nuances of additional users with your Google Fu.

Enjoy!
[Xperia Z3v General] AddictedToGlass:
Wow! Great work!
[Xperia Z3v General] Jurassic Pork Fried Rice:
Thanks! I really wanted this feature and it seemed like not many people care too much about it. It's my way of circumventing the awful permissions control we currently have in Android. That is, there are apps I want to use but refuse to install because of their overreaching permission requirements (contacts, etc) and so I can now create a second user with a new "dummy" Gmail account that has no sensitive information and install these apps without worrying.

By the way, something neat I figured out about this. Additional user accounts are not allowed to side load apps (the toggle to install from unknown sources is grayed out). I figured out that if the main user / owner restores an app through Titanium Backup, any other currently existing user will have it installed for some reason. I don't know why this happens but it's a neat glitch that gets you around that restriction.
[Xperia Z3v General] AddictedToGlass:
Well I think most people simply don't let others touch their phones and so don't have a use for multiple user accounts. I find that my phone, as big as the screen is, is becoming more and more of a computer / tablet replacement. I like the idea of a multiuser functionality, but mostly to hide my own stuff. I'll silk never let anyone else touch my phone!
[Xperia Z3v General] Jurassic Pork Fried Rice:
The use for multi-user that I've seen that makes the most sense is people with children. They will create a user profile for the child so they can't get into any of the parent's stuff or settings. That or the guest profile which will let them do whatever the heck they want without screwing up the phone.

Aside from that I have read that devs find the feature very useful for testing. Heck, that's not a bad idea to install and test apps, in general.
[Xperia Z3v General] rpelljr:
uh oh.

Well something didnt work. Maybe a certain build I have to be on or what. I followed the instructions to a t. Now stuck on endless boot loop. Only bad part is I'm on as hotel room working out of town without a laptop Or pc to fix it. I used a one click root just today and didn't install a proper recovery. Any thoughts
[Xperia Z3v General] Tigerhoods:
I had a problem with this also twice cause I'm always doing stupid things to my phone my guess is you didn't change the system to r/w but modified it anyway or you used a editor that would let you input the correct values I used s manager I think. As far as getting your phone working you could try safe mode or maybe a factory reset if you can hold power and the volume button down and enter recovery.
[Xperia Z3v General] rpelljr:
I believe the mistake was made when i changed the permissions per instructions. I finially got to my house and im using adb to freeze the loop then going to push a script over to fix the permissions. I will update when i get it done and I will post my fix. Also I used ES file explorer, which i have already used it for years now. Never had anything like this happen before. it just baffles me. I have never got any instructions off of XDA that led to any malfuntion of my phone. But oh well, sh!+ happens.
[Xperia Z3v General] Jurassic Pork Fried Rice:
Hey! I'm so sorry! I got a couple of new phones (Droid Maxx 2 and LG G4) and have been using those phones so I haven't been checking these forums like I was when I just had the Z3v. Really sorry to hear that you ran into that kind of trouble :(. Thing is, the instructions above are culled from 4 or 5 different sets of instructions for various devices that I found across the web. I performed them step by step myself while cross referencing them to each other and combined them all to the instruction set above as I did it. Did you ever fix it with the method you mentioned? I'm curious if it was the permissions thing (odd, because it worked for me).
[Xperia Z3v General] Tigerhoods:
it is guys if done right your system needs to be switched to r/w then go back to r/o after modifying the build prop if you modify in r/o you will get bootloop to a hard brick it depends.
[Xperia Z3v General] rpelljr:
Well I kinda fixed it. I went and bought a HTC M9. Lol but not yet, I'm still working on it. I have found scripts to run, even a specific build.prop fix to push, but I have windows 10 and couldn't get adb to find the device. Plus I'm a little rusty. So I broke out my old windows 7 laptop I have used just for rooting an modding phones and tablets. I did get adb and fastboot to find it once. Then some reason lost it. I didn't have it ready to go. But I'm almost 100 percent sure I can get it. Just need to play around with it a little bit more. Having trouble with drivers etc. I will let you know when I have it.

And didn't really hurt my feelings getting the phone I truly want. I never had problems with HTC since I was flashing roms on my old window phones. I just want my pictures I cannot replace.
[Xperia Z3v General] subs:
"Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)"

Alas- I am not rooted, and therefore can not enable "Root Explorer" option. Unless someone has some other suggestions- I think I can't do this unless I'm rooted.
[Xperia Z3v General] AddictedToGlass:
Well this is probably what I did to brick my first z3v.

I don't suggest anyone do this at all. There does seem to be an issue with the permission setting on the build.prop file. If it's not reset correctly after editing, you'll get stuck in a loop or worse. I'm stuck in bootloop, but can get into recovery. I made a backup hoping to learn how to edit the build.prop (delete it and rename the copied original to set it back as it was). But I can't even run the original zip that GigaSPX made up for us. (I don't have a backup like I hought I did.)

Anytime I try to install the flashable prerooted zip it tells me it's done after 2 seconds and says;

set_perm: some changes failed

I'm typing this on my z2 tablet, which has the multi user feature enabled. I'm going to see if RootExplorer will give me some clues as to why this doesn't work.

In the mean time I'm hoping someone can help me out?

If love to get this feature to work, but it has to be safe.

Just checked the build.prop on my tablet and got no clue.
[Xperia Z3v General] Tigerhoods:
a backup usually means going into your twrp and hit the back up button and make a copy of your system including data and all that. This is mandatory before messing with the build prop. If you want Pm me your build prop and I will send it back to you. With multi user enabled.
[Xperia Z3v General] AddictedToGlass:
Yup, I know what a back-up is and how to do it, and I know it's a must before messing with the build.prop. I just really thought I had done it recently...

-and I had! But I forgot that a few days ago I bought myself a Christmas present; a 200 Gb micro SD, and copied most of the contents to the new card from my old one. I chose not to copy the backup because I had planned to make some changes and create a more recent backup. Never happened though because I got side tracked loading music and such. Lol!

So I'm all back together, but would still like to play with this feature. So I'm going to give it another shot.
[Xperia Z3v General] leftfooted:
Perhaps the wrong thread but: enabled multi user on a Cube T8 only to find that guest and other user can access INTERNAL sd but not external sd. I'd rather have it the other way round. So the kids (other users) can use the whole of 32 GB sd card rather than me having to share the small internal sd with them.

Any ideas how to fix this? Phablet is not rooted btw.

[Mogul, XV6800 General] skinsraj28:
There seems to be a ton of posters here who know a lot about the Mogul and phones/PDAs in general...so I figured I'd pose the question to you all.

I'd love suggestions for what I should download...so if possible, could you respond with answers to the following questions:

1) What program?

2) What does it do? Please state the purpose/usefulness.

3) How do I download and install it? Link to find the download?

4) What, if any, existing program will be unnecessary once I download it? And can that unnecessary program be deleted?

I've never had a PDA, so any and all suggestions are welcome. I'll be using the PDA predominantly for calls, web-surfing, and messaging.

Also keep in mind that I'm new to all of this, and I'm a complete moron...I don't understand a damned thing. So talk to me like I'm a 5-year-old. I don't know abbreviations like SMS or MMS, or whatever.

Thanks in advance, I appreciate you taking time out to help me.
[Mogul, XV6800 General] killerkhatiby009:
Well one of the programs I use the most on my phone is The Core Media Player (TCPMP) it is by far the best media player for Pocket PC's and can play most file types. you can get more information from here, and if you want to download it just respond saying yes and ill post a link. Don't download it from the site as I have a newer version than on that site.

i hate to be the one to say it, but after seeing the views on this go up and no replies i'm just going to say what everyones been thinking. look around? theres hundreds of threads with stuff to download for your phone, you just have to look a little
[Mogul, XV6800 General] vijay555:
Most of our WM devices are very similar. As such, pretty much everything that's been said before still applies, so check the wiki, where you should find many articles related to this conundrum.

[Mogul, XV6800 General] skinsraj28:
Yeah, can you post a link? Thanks, I appreciate it.

And to you other two, I understand that...like I said, though, I'm a beginner and a lot of stuff goes over my head. So I figured I'd create a thread and can ask questions and whatnot.

It's fine if people don't want to respond, though. Life will go on. And some people have been nice enough to take time to explain stuff to me, so it's ok.
[Mogul, XV6800 General] Dishe:
Have you got .8?

I've heard rumors of its existance, but can't find it yet. Still running 0.72... If that's the newer version that you've got, would you mind sharing it?
[Mogul, XV6800 General] killerkhatiby009:
Here it is v.81, sorry it wouldn't let me upload to the site like normal so i put it on megaupload, to install it just download the file and copy it to your memory card or phone memory, then open it with file explorer on your phone and install it to either the device or memory card. Then open it from start/programs/media player

Sprite Backup

Sprite Backup is a must! Even if you keep it connected to your ActivSync PC daily, it is good to have a baseline you can always restore to, and I'd suggest having it backup to your SD card, and rename one of them every few weeks so you have something to restore from in case it gets completely fragg'd.

Another one is Skyfire (Beta) mobile internet browser.

I'd also suggest you get Microsoft Reader or EReader so you can have pocket novels on your phone (it's a nice thing to have when you're waiting for something). Also, rip your DVD's to your PC and encode them to WMV format and your ActivSync can put them on your SD card...

All of these tricks are discussed here in the forum. Hope this helps.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] rubin110:
Hi there. A friend I'm helping out with has a Z3 Compact. She doesn't like a bunch of the bloat that comes with the stock experience. I was thinking of helping her install AOSP on the device, but have heard around the water cooler that you do lose more than just the stock bloat ware. So far it sounds like the main big points that are lost are...

- Better camera for night time shots

- Better over all power management/saving

Is there anything I'm missing?

Beyond that, I'm wondering if there's a prebuilt AOSP based rom that has the camera and possibly the power management stuff rolled into it?

Thanks!
[Xperia Z3 Compact Q&A, Help & Troubleshooting] romcio47:
Basically if you want to switch to AOSP, you have to unlock the bootloader. When unlocking, it's recommended to backup .ta partition (so you can restore it when locking the bootloader to get back all the functions that will be lost when unlocking), because during the unlock process, you erase DRM data and that means (as far as I remember): no location sharing on stock SMS app, no xreality, no warranty and also I've heard that the camera possibilities are much more limited than on locked bootloader... and maybe there are more things that you lose because of unlocking BL.

I'd recommend disabling all the bloatware that disturbs her. Well, you won't be able to disable all of them, some has "Disable" button greyed out but most of the bloatware CAN be disabled. Also I'd recommend flashing stock, non-branded ROM.

All my previous Xperias had unlocked bootloaders but now my new Z3 Compact has it locked and I'm definitely NOT planning to unlock it. There's too much to lose after unlocking BL, that's my opinion.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] mcgrathpatj:
The biggest thing for me that brought me back to a stock (de-bloated) ROM was the camera. Quality is so poor. It's really night and day difference. Even worse, the camera relies on AOSP services and you end up with a "fish-eye" distortion. Photos with anything vertical look like they are curved and that's something i simply cannot live with. Quality of photos, maybe. Distorted photos, nope. If this were to be fixed.... I'd be right back to AOSP.

Created with Hardware Info 4.2.6

The App "USB Host Diagnostics" found nothing when i connect the Camera to my tablet. I have testet on an Android Phone from my colleague...the cam works perfect.

I think without a UVC-Driver the Cam will not work. I have read that the UVC-Driver is in the Kernel. But I am not familiar with this.

I dont have found a way to update the Android on the Tablet. I have found no custom rom. Is there perhaps a way to get an other Rom to work?

Is there a way to get the camera to work with these Tablet? It would be better than an expensive smartphone or an expensive laptop to use to inspect sewer pipes.

Many thanks.

I bought this nexus 5 from a previous user, noticed bootloader unlocked, diferente kernel(althought i flashed another already), but something caught my eye, im not sure if i have the stock rom, as i get an update of 16mb and fails.

"devcheck app"

Under system = Codename: Hammerhead

Is this stock?

I think nobody wants help a KILLER
[Nexus 5 Q&A, Help & Troubleshooting] Yaz75:
It is not stock. Unlocked bootloader is fine, everything else is a no-go. The different kernel is the glaring problem, you can not apply an OTA with that non-stock kernel. The first, most complete, easiest option is to flash the latest factory image. Seeing as this is a new phone to you, I can't imagine that you have a ton of personal info to save. For me personally, I'd flash the image just so I know that I'm starting with a fresh clean slate. Then you can read up and root/mod how you'd prefer.
[Nexus 5 Q&A, Help & Troubleshooting] HIGKILLER:
I have experience with custom roms all that, i did flash this kernel, but the room, is what bothers me. and thank you, i was kinda sure this wasent stock rom! Thank you
[Nexus 5 Q&A, Help & Troubleshooting] Wakamatsu:
Not enough information from this to say. The custom kernel you installed is enough to prevent OTA updating.
[Nexus 5 Q&A, Help & Troubleshooting] HIGKILLER:
i can never find a decent post, how can i be sure this is stock rom, without having to flash the stock one?
[Nexus 5 Q&A, Help & Troubleshooting] Wakamatsu:
It would be easy to say if the build didn't match a legit N5 image. If the build info in build.prop isn't informative, look for apps/features that shouldn't be in a stock image, eg. AOSP apps replacing the Google versions. Unfortunately, you do have to have some familiarity with stock Google to be able to spot something that's out of place.

[Nexus 5X Q&A, Help & Troubleshooting] alnova1:
Since I trade or sell phones as much as I go to take a leak I'm not sure if it is for me. I know the warranty is transferable but don't think I will. If you keep a phone for a year or 2 then it might be.
[Nexus 5X Q&A, Help & Troubleshooting] rickyray9:
IMHO phone insurance is only worth it for police, firefighters, athletes, construction workers, crash test dummies, people with small grabby children, etc. I always just go with the $10 case because I haven't broken a phone in 8 years.
[Nexus 5X Q&A, Help & Troubleshooting] Tidbits:
I agree with Rick. I would also like to add if you are accident prone.

I got a thin case and that's it. I thought about getting it since I have kids. Then thinking about it. They only broke 1 in 9 years(one is 4). He broke it by jump kicking it out of my hands (came home and he was happy to see me).
[Nexus 5X Q&A, Help & Troubleshooting] clninja:
Insurance IMHO is ONLY worth it for manufacturing warranty being extended and loss/theft.

Nexus protect does the warranty but who keeps there phone for more than a year anyways.

It doesn't cover loss or theft
