Lenovo A7-40 multiuser/restricted profile - "app is not installed" for every app - General Questions and Answers

Lenovo A7-40 multiuser/restricted profile - "app is not installed" for every app
Hi everybody,
for mentioned tablet with Android 4.4.2 I installed CWM (which gets always deleted after reboot) and rooted the tablet in order to activate multiuser/multiprofile. This worked out so I could set fw.max_users = 4.
Since the tablet is used by our little daughter I installed Kids Place in order to restrict as much as possible. Unfortunately booting into "safe mode" bypasses kids place completely and provides full access to everything (she found out by accident). So I tried to get rid of this problem by trying to create a restricted profile which did not work since the installation did not finish normally and for all assigned apps I get the information "app is not installed" (while it is shown and can be clicked on).
So I tried to setup a second complete user. But same problem here: Installation did not finish normally (also black screen and running circle forever) and afterwards none of the shown apps can be started from homescreen (while I could start playstore from within settings/apps menu): Message: "app is not installed".
Does anybody have any idea how to get this topic solved? Either by preventing the safe mode being able to be used without kids place or by creating a restricted profile which works as expected?
Many thanks in advance!
Bye

[Q] app defaults restore after every boot(after rooting)

hello.
i have a moto G dual sim indian version.
i rooted it yesterday, following the method given by this site: androidadevices>motorola>moto g
everything was perfect exept for the last step. after entering the code
superboot-windows.bat
in cmd it indicated i have succeded. but on my phones screen the boot animation appeared and dissapeared in a fraction of a second.
i waited. then my screen turned purple and faded out from the edges to the center.
i waited for about ten minutes and then removed the usb. then i held the power butoon for about 8 seconds and then the phone booted up.. but it took longer than usual. it turned out to have super su installed. i even checked with the root checker app which also indicated my phone is rooted.
now whenever i reboot my phone, it still takes as long as the first time it booted after rooting, i noticed these things:
1. the notification saying "clear a notification by swiping"
2. i had set the google launcher as my default launcher when i boot it goes back to motorola launcher.
3. i had even installed lmt launcher in which i set up the pie controls and checked the box for "start on boot". it did not start on boot and my pie set up was gone.
4.i cant send/ dwnload images in whatsapp.
please help me. have i gone wrong in the process of rooting? (Or is it normal? )
[and also google play services kept crashing i cleared data under app settings and it stopped.]
thank for your time

[Q] Titanium backup - can only restore few apps

Hello,
so far I did not find a similar problem anywhere.
I did a backup of all my apps, played a little bit with some custom ROMs and now I am back on my initial ROM (dokdo).
My problem is: I can only restore very few apps.
If I choose the batch mode several apps are simply skipped without any error message. During the restoration within the "restoration is running" window I see the name of the skipped app for a very short time and the immediately the name of the next app.
When I go to the menu where I can manually restore single apps I noticed that only apps with a smiley at the end can be restored and the ones with a tick not. Unfortuantely again no reason is shown...
By the way: I updated the "super su" app.
Does anyone have an idea what goes wrong?
Cheers
oetzi
Anyone an idea?
Did you Google the meaning of those smileys?
I am assuming it has something to do with them, since if an app wasnt correctly backuped, you would be simply stuck while restoring that app...
Good hint, I only googled for "apps cannot restored".
Under menu -> legend you can see what the symbols mean and the ticks stay for "only data available" which confuses me even more since that means that the backup did not really work...

[SOLVED] Limited functionality

This thread was originally titled "System wide problems", please see the reply for the solution.
Original post:
"Hi all,
Been forever since I've made a post to XDA, but I have a problem I'm not able to solve without taking an inconvenient plunge. I should mention that my phone was 100% fine yesterday evening, but since I was asleep last night it seems to have run out of battery, so this morning I charged it a bit, then I turned it on to a world of problems.
Ok, so let me run through a list of just a handful of the problems I'm having right now...
Totally stock (not rooted) Nexus 5 running Android 6.0.1 (Security: 1 March 2016)
1. Home and App switch soft keys don't work
2. Notifcations are not working at all
3. Notification shade wont pull down
4. Widgets cannot, and will not load
5. Cannot get into Developer options "Developer options are not available for this user"
Seems I'm not the only one to experience the strange bug, some folks over at Android Central were experiencing the exact same thing toward the end of last year.
http://forums.androidcentral.com/an...me-button-not-working-many-more-problems.html
Some people to have resolved this issue using "adb shell am start -n com.google.android.setupwizard/.SetupWizardTestActivity" but I cannot get into Developer options to turn on USB Debugging (unless I don't need to?)
What I've tried already...
1. Cleared all Google App data "CLEAR ALL DATA"
2. Tried to make another user, just flashes and goes back to "Opula" my main and broken user profile, never creates the other profile, same thing happens when I press on Guest too
3. Safe mode, but the problem persists there too
4. Virus scan, turned up a whole lot of nothing
I'm now at the point where I'm thinking I'm going to have to do a Factory data reset (the "inconvenient plunge"), even though I think I've backed everything up the "Touch to sync" option on my Account > Google doesn't do anything, neither does the "Sync now" from the drop down menu. So despite having explored my Google account on my desktop I cannot see if it has backed up my Apps and App data, but it seems to have backed up my contacts and such.
I'm going to get a third party app to back up as stuff as I possibly can as well, but even Helium is useless now since I cannot get into the Developer options so enable USB debugging.
Anyone got any experience with this issue or how to resolve it?
Many thanks to everyone in advance."
Hi all,
Just wanted to update this thread to say that I did a factory reset and the phone is now fixed, but I wouldn't to give a more comprehensive account of the problems I was experiencing with the phone until I did the factory reset.
List of problems
Home and app-switch soft keys not working (back key is working)
Google Now 'on tap' not appearing (cause of home key)
Cannot see notifications just says "No notifications" (but the light and sound work fine when a notification is received)
Cannot pull down notification shade to toggle controls
Widgets cannot be added and will not load
Cannot pull down the immersive mode overlay
Google Backup not working (after 8+ days)
All types of syncing not working
Phone's storage doesn't appear on PC when plugged in via USB
Cannot access developer options (due to active profile level)
Cannot create or switch users
The best advice I can give to mitigate such an unusual problem (that appeared totally out of the blue on a cold boot) is use Google Backup services, keep on top of syncing, and manage your data via your Google account! Or as an alternative, manage and maintain manual backups.

How to turn off/disable application (no root)

Hello.
Im changed my device from S4 (kitkat) to S7 (marshmallow) and Im really annoyed of many changes what google did, but I had no choice.
My question is following,
how to temporary turn off/disable selected application like messanger/viber etc. I tried in app manager "Force stop" but after some short time app started itself, and I get back receiving messages.
Is there any way to turn off selected apps until I will run them manually ? Are all apps really must work in background ?
Please help me Im so annoyed of that version of android
Most of use use this if we're not rooted

Wiko Lenny 3 + Marshmallow + Root + Xposed + Autostart bug

This is not meant to be a detailed tutorial, but rather an overview of the struggle I had to root and modify a Wiko Lenny 3 (with links for convenience), so others can benefit.
About a week ago I purchased a Wiko Lenny 3, a device with minimal RAM specs (1GB) for Marshmallow. This creates problems with app-notifications due to the Phone Assist (/system/vendor/operator/app/ApePhoneAssist) and Protected Apps (/system/app/CustomWhitelist) software that is pre-installed by Wiko to compensate for the low RAM.
First, I freshstarted the phone and put in the basic configuration. I immediately updated the system to OTA version V54.
Then I flashed TWRP 3.0.3-0 with SPFlashtool from this site:
http://www.needrom.com/download/recovery-twrp-wiko-lenny-3/ .
There is also TWRP 3.0.2 available but that DID NOT WORK on my phone:
http://drive.google.com/file/d/0B6isv8b6duCrbjdJbDVlRFpONlk/view
After that I rooted the thing via TWRP with SuperSU.zip, and installed Xposed via TWRP. I debloated the phone by removing most Google trash.
I use Syncthing to sync the contents of my external SD card to other devices. But Syncthing needs write permission on the SD card and Marshmallow mounts the SD card read only, and can only give write permission to the ./Android folder on the SD card. I fixed this with XInternalSD. The other option, Marshmallow SD Fix 2.0, DID NOT WORK.

http://forum.xda-developers.com/xposed/modules/xposed-marshmallow-sd-fix-write-t3403263
So far, so good. However, after a while I noticed that FaceSlim (lightweight FB client) did not send push notifications. FaceSlim works perfectly on my old KitKat phone and also on a Lollipop tablet. So I checked running processes with OSMonitor and it turned out that FaceSlim was not being autostarted at boot. Some other services were not autostarted at boot as well:
AFWall+
Applock
DataStats
EZ Wifi Notification
FDroid
MaterialFBook
WiFi Automatic
Xprivacy
I have K-9 Mail installed as well but that app actually DID send notifications, for a while at least, later on it would not work anymore.
DataStats would not stay on screen if I forced closed it after starting it manually.
AFWall+ would only start if I added the widget on the home screen.
I tried every recommendation, like disabling doze mode for all apps and whitelisting the apps in Wiko's "Phone Assist" app, an overly aggressive resource manager that is shipped on Wiko phones, probably to make up for the low RAM. Nothing would autostart the apps.
So, I decided to flash the phone to its original state, using the official vanilla ROM from Wiko (V54), just to see if rooting screwed up the phone:
http://nl.wikomobile.com/maj.php?telephone=1246
After flashing the phone, I tried to get notifications from FaceSlim, but that still wouldn't work, so i guess the problem was not in my rooting the phone.
I also tried to flash TWRP again but this DID NOT WORK WITH THE DOWNLOADED ROM FROM WIKO (as opposed to the OTA update). TWRP got installed, but the phone would hang at startup at the Lenny logo, not booting to the UI.
Fortunately I had a TWRP backup of the old system and I flashed it, I could again boot into the UI now.
I found that other users experienced similar behaviour:
http://www.android-hilfe.de/thema/a...enachrichtigungen-funktionieren-nicht.781196/ (German)
http://android.stackexchange.com/qu...ground-sync-processes-wiko-lenny-3-what-to-do
As said earlier the Wiko has two pre-installed apps that manage autostart behaviour and power management.
1 - The "Phone Assist" software has a "Boot Optimize" screen. This feature does work for some apps, but not at boot level. When I deny autostart for AFwall+, it comes up after a reboot and is killed shortly thereafter. If I disable everything in Boot Optimize, the switch for Applock and Wetteronline returns to enabled after a reboot. Moreover, it cannot prevent Instagram from starting, one power hungry app.
2 - Phone Assist also has a "Power Management > Power saving" mode presumably to restrict network acces for apps in screen-off mode. This could be the same as the 3rd party Doze apps on Google Play that use a local VPN to restrict per-app network acces in standby mode. It is debatable if this saves much power, and there could be a security risk.
3 - Phone Assist also has in "Power Management > Advanced > Gear icon > Whitelist" (free translation, my language is Dutch) a screen to "whitelist background apps". If you whitelist an app here, it is simultaneously enabled in the previous menu ("Power Management > Power saving"), so I suspect this menu is redundant.
After playing around with the various settings in "Phone Assist", NOT A SINGLE APP WOULD START AT BOOT ANYMORE, even if I whitelisted all.
4 - The "Protected Apps" feature, found in the Android Settings, will allow you to whitelist apps for autostart. If you put this app in default mode, it will select some apps to start at boot by itself. If you whitelist apps, they indeed do start at boot. But "Protected Apps" has a limit of four apps that are allowed to autostart. This makes use of the phone for social networking/email very limited. Some Huawei phones have this feature too, and also with a limit of four apps. This is clearly an attempt to make up for the low RAM in this device, preventing users from running too many background apps. "Protected Apps" overrides all "Phone Assist > Boot Optimize" settings, making the latter effectively useless.
5 - On top of that there is the native Marshmallow Doze mode, which requires that you whitelist apps from Doze power management.
As you can see this is a complete mess. To enable/disable an app from autostart or power saving modes you have to visit two to five configuration screens. Tinno is the company that programmed this disaster (http://tinno.com/homepage?lang=en). Actually Wiko phones seem to be rebranded Tinno phones.
"Phone Assist" also has a junk cleaner (powered by Purify) that notified me once in a while asking me to delete SEVERAL GIGABYTES of junk. I had absolutely no desire to try that one ...
You can find so-called fixes on youtube for background apps that don't start, which involves installing QuickShortcutMaker, and enabling Low RAM via One Clean. That does not work on this phone.
There is a way to circumvent these autostart/powersave restrictions without removing the Wiko apps. With Link2SD or LuckyPatcher you can convert a user app to a system app. That way the app will start at boot and will send you notifications as well.
However, I wanted to get rid of this badly programmed mess altogether, and keep my apps running as user apps, so I have removed Phone Assist, its separate uninstaller, One Clean, and Protected Apps.
After deinstalling Phone Assist with SDmaid I manually removed "/system/vendor/operator/app/ApePhoneAssist" and "/data/dalvik-cache/arm/[email protected]@[email protected]@@[email protected]@classes.dex"
In /system/build.prop I edited the line "ro.tinno.whitelist.set=true" to "ro.tinno.whitelist.set=false". I don't know what that line does exactly, but it's just to be on the safe side. I think this setting is overwritten if you reinstall Phone Assist or Protected Apps.
I whitelisted some Social Media and Mail apps in Marshmallow native Doze mode.
After a few reboots some of my autostart apps started to reappear at boot, but not all. Only after I started the missing apps manually from the launcher they would appear after a reboot, and persist.
Later, I made a TWRP backup, and after that I wiped the cache and dalvik/art-cache with TWRP. Evertyhing went well.
Wiping the dalvik-cache can be a risky thing, it once left me with Android trying to optimize nine apps at every boot. I turned out that those were apps that I converted from user app to system app, and back. I removed those apps and reinstalled them and the optimization at boot went away.
So now every app starts at boot as it should, but it would be nice if this "Protected Apps" feature would not have a limit of four apps to boot, because then we would have a nice integrated boot manager. If anyone can find out if it is possible to modify this limit I would be much obliged
EDIT: So, three years later and I still have this phone. I have recently installed update v59 and encountered the same problems. After deleting PhoneAssist and ProtectedApps only a few of my apps worked right, and that was only after multiple reboots. Other apps would still not show notifications. However after I edited /system/build.prop and changed this line to "ro.tinno.low_memory=false" all apps suddenly worked correctly. Maybe this would even work with PhoneAssist and ProtectedApps still installed, but I don't care to find out at this point.
Didn't work for me, but...
Hi,
If someone has the same problem and stumbles on this post...
Setting ro.tinno.whitelist.set=false didn't work for me, probably because I aggressively modified the stock ROM to remove most of the vendor apps (including this PhoneAssist and Bootclean crap).
What actually worked for me was to set ro.tinno.low_memory=false. After that, all apps supposed to start at boot, actually did.
Once I'll finish my tests and use the phone for a couple of weeks, I intend to post a complete guide explaining how to uncrappify this phone (it's wonderful what you can do once you manage to successfully flash TWRP).
Wiko Lenny 3 2 gb RAM and 16 gb ROM
Hi guys, I have a clone of Wiko Lenny 3 commercialized in Tunisia under the name of EVERTEK EVERSTAR PRO 2. The device that I now has 2gb Ram and 16 gb of Internal storage, but the original version of the Wiko Lenny 3 has only 1 gb Ram. I confirm that is exactly the same device same processor same camera and screen. So I was wondering if I can flash my phone with the official Wiko Rom ? Does android indentifie Ram and Internal storage from the Phone ? Pleaaase Help me .. and sorry for my English

Yes, I installed update v59 and "ro.tinno.low_memory=false" works for me too, thanks!
