Whatsapp Re-launching

Hey everyone,
This is intended to people who use Whatsapp or apps that show similar behavior.
If Whatsapp is in the background app list, I can easily hold the back button, access the list, and click on it and it will resume from where I was.
However, if the background is still in the background app list, and I clock on the Whatsapp live tile, the app has to re-launch itself instead of resuming from where I left it.
Is that a Whatsapp malfunction or normal WP7 behaviour? Other apps do not behave like that so I am guessing it's whatsapp.
I only had my Lumia 900 for a week and still new to WP7.
Your help/comment/feedback will be appreciated.
Thank you.

clicking on the app-tile will force every app to relaunch (except some built-in "apps" like your browser and so on)

I find that a bit odd don't you think? What for?

It's a limitation of Windows Phone right now. I think it's mostly done to reduce the amount of background processes running and hence will give better battery life.
Hopefully this will change with WP8!

Actually, that's mostly incorrect. It is the default behavior of WP7, and the reason for that behavior is to allow the user to re-launch an app that has become hung in some way (since apps can trap teh Back button, it's entirely possible to make an app that the OS provides no other way for the user to exit from). In theory (I haven't tried it myself), it's possible to make a configuration change that causes the default "launch" behavior to be resume, rather than restart.
Background processes are completley irrelevent, because WP7 has no (significant) process limit and does not let apps run in the background (consuming battery) anyhow. Backgrounded apps are fully suspended; they use RAM but if another program needs it, the suspended app will be tombstoned (think of it as "hibernated"), the process ended, and the RAM freed.

Interesting although a bit annoying since the app takes 5 seconds to relaunch and fetch messages although the messages have been received and notifications have appeared on the top.

[Q] Background processes killed since Lollipop update?

Hi there,
since the update to Android 5.1 and EMUI 3.1 some services like Whatsapp wont work properly.That means for me:
- Push notifications from Whatsapp and Snapchat will only arrive, when I open the app -> sometimes, when I close the app from the task manager or leave it over the night
- Whatsapp forgets the names of my contacts and only shows the numbers (some background service not running?) -> fixable by "updating" the contacts through Whatsapp. Happens at least 5 times a day, even when I'm not closing Whatsapp through the taskmanager.
Every permission I could find is activated, I guess it's some kind of automatic battery saving, which I'm unable to find.
Thank you very much,
Julian

I used to have that problem as well after updating my Honor 6 to EMUI 3.1 based on Lollipop 5.1.
Updating WhatsApp to version 2.12.278 (link in the FAQ section in the official website) seems to improve. However I still have another problem which could not be resolved, I could not change the notification sounds.

you need to set your apps to be protected at Settings -> Protected apps to prevent them to be closed automatically by the system
hope it helps

I have Honor 6 too, don't updated till now. And i have another phone with Android 5.1 with same problem. Is there any third party App like "protected Apps" from Huawei? I don't have any chance do get my backgroundservices running, that unbelievable :crying: who decided this? The Charwoman? I mean, android without backgroundservices = no mor messages in lock screen.
And when i leave app open, battery usage is 4x stronger then background service....

I have runkeeper protected and still after about 1h of usage it simply stops with no errors...
I'm on an early version of DEV (rom), I think I'm going the "stable" route next.

I have the exact same issue, came across this thread looking for answers. RunKeeper (and I assume any other app as well) is simply killed after about 1 hour. I usually use my phone during walks, to for example take pictures, answer chat messages and whatnot, so I thought the issue could be that I was out of memory and that is why it closed the app. To get to the botton of it, I tried the following steps:
- Reboot the device
- Clear everything from the multitask menu
- Make sure RunKeeper is set as a "protected app"
- Start RunKeeper, begin an activity
- Keep the app open, i e not going back to home screen or opening any other app
- Waking the screen every 5 minutes or so to make sure it doesn't go into some deep sleep mode
Result? After about 1 hour, when I pick up the phone and unlock it the RunKeeper process is simply gone, killed by the system. By the way, for me it's a Huawei Mate S device, but this seems to be an EMUI issue. I'm on EMUI 3.1 (B145 europe, official release). Just thought I'd chip in. This is annoying to the point of being a dealbreaker to ever getting another Huawei until I can confirm it's fixed.

I have this problem constantly. I installed an app called "pnf no root" but it also helps temporarely. I really like my honor 6 [ h60-L12] but this is a really annoying problem. I realize that huawei doing this save battery power, but this is ridiculous. What's the point of protecting the apps if it doesn't do anything in the first place ?

Hi, I have the same problem with my Honor6 [h60-L04C900B521]. I talked with technical support and they told me to install an application locking the GPS signal . Check if it works with Endomondo + GPS Connected app but this can only fix the endomondo problem I hope.
Edit. 10.04
Unfortunately this application do nothing. Endomondo was kill after 1 hour running. Anyone have idea what to do with this?
Edit 11.05
Finally after update to marshmallow there is one option to keep endomondo while workout. Under battery in right-up corner there is settings icon and there is option "close excessively power intensive apps running in the background" this option actually works fine.

How to keep Apps running in the Background?

Hi everyone, ever since the update, my apps stop running in the background when I close the app. Example: I don't get Whatsapp notifications anymore unless I open the app and keep it open. If I close all open apps, I will no longer receive any of the notifications for any of them.
I went into the battery settings disabled battery saver mode but that didn't do anything.
I would appreciate any help you could provide.

It's apparently one of the issues with the latest OTA update, where closing all running apps will terminate the background processes associated with the apps closed. Prior to the update and the Close All button being added to the recent apps list, I don't think it had this problem (I don't use Whatsapp, but my Skype and Discord notifications still come through even if I don't have them on my recent apps list).

This is a little frustrating. Noticed that I wasn't getting any notifications from tasker, pushover, textra, hangouts, inbox and etc.
Also noticed that pushover will not update unless it is off of wifi. All my other devices receive notifications on this wifi. IE nothing blocked.
I have had to open all the programs that I want to receive notifications from, open. Not the best work around.

I noticed that on occasion there will be small text under the new button that says "long press to set up apps that could run in the background" I do it but it doesn't seem to do anything, maybe free up some of the RAM but that's about it. I'm wondering if there is a bug and if it's supposed to show something.
Has anyone else tried the long press?
As of now all I do is keep a folder on the desktop labeled background apps. It helps big time when I accidentally tap the close all button. But my solution as of now is to keep things open that don't seem to work in the background. I've been experimenting with what works and it seems like in some recent app updates they begin to work without being open. I know for sure that facebook and now facebook messenger work without being open, as well as some google services. I have a memory clearer app that I use when I'm not using my phone so it clears whatever it can without killing the apps. But that's what I have as of now, trial and error to figure out what I need to leave open and what I can close. And I strongly recommend the folder, I have had many times where I accidentally close everything and forget what I had to leave open.
It's a bummer though, I just bought the phone and then this update came out. Kinda kills the excitement of getting a new awesome phone if I have to deal with this frustration :/ Other than that, it's definately a nice step up from a Samsung S4.

does it misbehave after rebooting? or all the time?

Misbehave as in not show anything after a long press?
Yes, nothing happens anytime I try it. After reboot, the first time I pull up the running apps is when I get the prompt. After the first long press after a reboot, the prompt is gone. If I have an app open and then I do the long press, I am taken back to the desktop, but no matter what I try, nothing seems to happen after the long press other than being taken back to the desktop if I had an app open.

I have the same issue, I thought it was a Internet connection issue (see my thread) but after digging deeper realised my background apps werent running after closing them and the long press option does nothing.

I have the same problem. Any solution?

I've just installed the new update and it looks like the issues I had with background apps closing when clearing all apps has been fixed. I've got no apps running in the foreground yet can see Whatsapp, Fitbit, etc still running and I'm receiving notifications for them.

Anyway to uninstall the memory manager?

The awful program that keeps closing out my running programs and also refuses programs to run in the background. I am missing Email notifications because of this. My ESPN app is pretty much useless because it isn't running in the background to send me my score/breaking news notifications through out the day. I thought it was just Android Doze that was the issue, but even if I turn the apps off optimization they still get closed out by the awful memory manager that Lenovo has running.

AccuWeather, which puts a current temp notification on the notification bar, also shuts down after one to several days. Thought it was an app issue. Other apps have no problems annoying me with unwanted notifications.

So Lenovo has this also? Like Huawei with there phone manager app. I was looking at the Phab Pro 2 because i love my Honor Note 8 but notifications sucks on this phone. Yeah you can freeze it, but things like battery manager don't work any more.

Try ####6020# Select PK
Backup yr phone first.

Question Permissions Issues

I like to stop background data and set battery use to restricted for most of my apps.
I spent about 10 minutes yesterday going through every app and turning off background data and setting the battery use to restricted, but after a reboot, everything is back to default, including apps I've previously enabled to install other apps (Google chrome, mixplorer, sai, etc)
Any ideas?

Here is something that I do to achieve a similar result. I use the app Ice Box to freeze many of my apps that I want to restrict. This temporarily disables them, but keeps their data. This cuts down on battery usage, background CPU/RAM usage, and notifications. Whenever you want to use one of those apps, you can just tap the icebox icon and it will show a panel of all of you frozen apps and you can just tap an app to open it. It does offer the ability to put shortcuts of the frozen apps in your launcher to make it easier to access them.
If you are rooted it is simple to set up. If you are not rooted, you can still use it with ADB permissions (works well with Shuzuku too), but you need to reissue the adb command anytime your phone it rebooted. Shizuku makes this step a bit easier.

Thanks @synesthete, but my use is different. I've used SDMaid and other apps to freeze apps for years, but that's not what I'm after.
For instance, I don't think Google Chrome needs to have background data when I'm not actively using it. I also think that there's no need for it to have "optimized" battery setting if I only want it running when I want to use it. There are a lot of apps that fall into this category that I'd like to be in control of.
So in short, I want to disable background data and set it's battery use to "restricted", which works right up until I restart my phone.
I hope this isn't some new "intended behavior", that'll suck.
Battery life is part of my concern - apps that are on the "restricted" list don't use as much battery, and I couldn't care less if I get notifications from most of them, but I still want to use them.
Background data is more privacy-concern. I don't think most of my apps need to call home and tell them what I've done in their app since last time it called home. My invoicing program for instance. I need that info synced, but when *I* choose for it to sync, not 14 times in the middle of the night when I'm not using the phone.

Yeah I understand your reasoning and I agree that many apps like that do not need background data or to even run run in the background. I suppose some people use web-apps/PWAs and push notifications in their browsers, but it seems that background data should be an opt-in setting for many apps.
It is very strange that those settings are resetting after reboot. I just tested it out with Chrome and Chrome Beta and the restricted setting survived a reboot.

Damn, ok, at least I know there's something wrong with specifically MY setup.
Hopefully someone will chime in with a reason and a fix.
Thank you for checking it out on yours and giving me input!!

I hate to double-post, but it's been a couple days and I was hoping that someone with experience in what my issues is would chime in.
tl;dr the initial post:
I set specific apps to restrict background data and set the battery use to restricted.
After a phone restart, the settings are back to default, including any 'disable over' and other permissions. My changes do not persist after a reboot.
