P8 lite B574 vs Mobile data usage management

Hey there,
2 days ago, after i got back from a wedding, i was surprised to see i used to much mobile data and got billed from my provider.
So, because i do not want to happen again, i said to myself: "I'll set a data limit for mobile data". Well i can set a limit but i cant set the billing period.
My billing period is from 8th to 7th next month. Today i'm in 25th, my mobile data is OFF, and i don't know what to do. Where can i find the setting for billing period?

I got ALE-L21C432B574, no root, no custom rom, no custom recovery, just official updates. Any advice what to do?
If i wait to be on 8th August and set the Mobile data limit, is this gonna also create a hidden billing period?

I hope someone can help me.
Regards, V.

*RANT* bad Android memory management

Guys I have problem with Android smartphones. I am not the youngest anymore and remember the first PCs and first smartphones with 32x less memory then an average handheld device has today. I played with them all and know what they could do. The thing that still continues to surprise me till today on Android is WHY the heck can't an app stay in memory without being quit on the first occasion?? I really think that Android will never be usable for any serious work if things keep closing or reloading just after a few switches between apps!
Some examples: why can't I switch between Chrome browser and Onenote to type something without having that webpage be reloaded again using more data and sucking more battery power? I learned not to risk writing any bigger post into some forum lately because if I would have to switch to another tab to check some info or switch to another app the in progress text would most likely be lost because webpage would reload! Why is it so risky to switch out of some game to write a message or check calendar because it is very likely to be killed and my progress lost? The phones I used recently (Xiaomi Mi2s, Xperia Z3 compact, Xperia Z5 compact) have frikin 2GB of memory, so I wonder if nowadays apps are so much more memory demanding then before that this is simply still not sufficient. I just checked settings and some apps I just tested use few tens of MB, so it is still comparable to the times of Windows 98 or Windows mobile IMHO.
My first smartphone was windows mobile Samsung Omnia II with just around 90MB of usable memory and let me tell you that this problem was not happening on it! I could have several tabs with webpages (even non mobile versions) open and could safely switch on the camera, take pictures, write an sms and go back without having to worry that anything will be closed or reloaded! Why can't I open a camera app on Android and take a photo without having the previously open app be closed?
I can even compare today's android phones to one of my oldest pcs back in year 2000 or so. Imagine that it had just 64MB of RAM. I could have open many webpages in Internet Explorer (yeah it was far the best at that time , a few editors for web and text editing and I could even play some game and alt+tab back and forth without any problem! That was Windows 98 guys. Of course you will tell me that today's web pages for example are much bigger then in 2000. OK but what about mobile versions huh? I don't think they are that big so a phone with 2GB of RAM would choke.
I always thought that apps are supposed to be paused/frozen when I switch out of them but left in memory. Unfortunately it seems apps are being killed surprisingly often even when settings / memory shows hundreds of RAM free. The thing that is even more weird to me is that apps I had open just a few seconds ago are being closed upon switching to some other one and back, but the ones which I had active hours ago often stay in memory! That does not make much sense. Why doesn't android kill the longest not active apps first instead? OK, so do I have to buy OnePlus 3 or Meizu Pro 6 with 6GB of RAM to be able to keep simple 3 apps open without worrying that they will reload when switching out of them? As I showed this does not happen on much older devices with similar specs, so is this some fundamental flaw/feature of Android architecture or am I missing some simple explanation?
If you have experience with Windows Phones or iOS regarding this please share and compare.

FDE and desktop management software

Hi,

Hopefully this thread meets the criterion of being a discussion about physical device security.

Having just mislaid a Sony Xperia Z3 Compact/5.0.2, I've decided to use the opportunity to invest in a phone that meets my security requirements.

Specifically, I need a phone that offers FDE that is compatible with the default desktop management software (ie. not adb) using the official, unrooted ROM.

So, for example, AFAIK none of the Sony phones nor any of the Samsung phones meet this criterion, because as soon as FDE is enabled, you can no longer interact with the phone using the manufacturer's desktop management software for the purposes of:

• backing up text messages and call logs
• managing media on the internal storage
• making and restoring device backups

There are other criteria that I'll be applying, but it seems best to start with this one.

I'm also keen to understand why this is such an apparent issue (IME) for Android-based phones. Is it a fundamental architecture issue?

Sim data management issue!!

So, in my last phone i could set a target or a limit to the mobile data. So the phone would warn me around 200mb before the limit and when i hit the limit it would stop the data...
Is there any way to set a limit in honor 5x???
Thnc in advance

Dual sim data management

Hi mates,
is there a mod/apk to check/manage the different data consumption ?
With the single sim I used 3G watchdog and I like the widdget options to check the real time consumption and also the estimate consumption. Unfortunately Watchdog and other similar apk cannot make different management for different sim card. It seems it sum the different consumption of the two different sims giving you back a unic estimate.
Do you know if there's something more smart than checking each time the sim setting menu ?
Thanks

app for permission management

Hey, so just wanted to ask if anubody knows any apps/xposed modules to revoke permissions and such?

[N preview] Double System Android in battery usage and memory management

Hi guys,
Currently I'm using N preview [locked bootloader, no changes) and in e.g battery usage and memory management I have Android System and Android OS. Okay, but isnt it the same? In Android System i have included packages, in Android OS nothing, and mosty it uses mosty memory and battery. Why does it happen? My phone can hold about 2,5h SOT and that's not a good score, because when i was running on franco kernel it could hold about twice longer.
Android System after all day uses about ~800 mAh, depends from as I use.
So, is it normal? I'm not going to root phone again because it's enough smooth, just battery life doesn't contents me.

About RAM Management on X86 platform

Hello everyone!

First the video link ( is in PT-BR, but my text has the translation of the point of interest ) :

https://www.youtube.com/watch?v=KiS1463v92o

Recently, the marketing manager of ASUS Latin America, Marcel Campos gave an interview for these guys to talk about the launch of ZF3 in Brazil , and also the ZF2 that are very successful here.
They were told many things , but one in particular caught my attention :

From 31:00 video , when they spoke of ZenUI , the interviewer asks :

- " If the zenfone has 4gb RAM , why ASUS included a RAM cleaner in ZenUI ? "

And Marcel Answer:

- " Simple: Because of the X86 platform."

I have no knowledge to contest this information , then I would a developer who understands RAM management opine about it . Is that really true? What changes in android management ARM vs. X86 ?
