As you absolutely refuse to educate yourself on this, I'll try and explain it in simple terms for you -

Let's assume you have decided that you want to keep an arbitrary figure of 800MB of free RAM.

- You have the following user apps loaded into RAM already (just example made up figures) -

App A - 100MB

App B - 60MB

App C - 150MB

- You are at the magic number of free RAM you want to see.

- Then you open App D, which is 75MB. It's loaded into RAM, which reduces free RAM to 725MB.

- As you have decided that free RAM mustn't fall below 800MB, App A is killed to free up enough RAM.

- Then straight after, you want to switch back to App A. As it has been removed from RAM, it has to be loaded again, which is slower than bringing the cached process to the foreground.

- The amount of free RAM is again below the number you want to see, forcing another app to be killed.

From this hugely simplified explanation, you will see that wanting a large amount of free RAM actually hurts multitasking.

Frequently used apps being cached in memory is a good thing. Why not let as many as possible stay there until they absolutely need to be killed to make room for something else?

I'm not saying that all the memory should be used up at all times (there is actually a minimum oom value set), but it's ridiculous to suggest that more than 400-500MB needs to be kept free to ensure your phone runs smoothly.

Why have devices with large amounts of RAM if it is going to be left empty and therefore wasted?
[Xperia Z General] Tommy-Geenexus:
Bro i agree with you.

But there is a service constantly eating ram in the background, that's why the free ram is, compared to other 2 gig phones, relativly low.

But its not proven actually.

I'm not complaining as i enjoy my Z.

Maybe i just became a junkie cause i just got a nexus 5.

Again. Do you see RAM decreasing on modern devices?

Or increasing? Maybe you want to say the less RAM the better?

Really? So what, manufacturers are idiots? Or MAYBE modern OS'es are more and more hungry, that's the reason? Knockknock.

And what is WASTED? What a silly thing.

I put it simply - the more RAM in general, the more space to operate and to be used by any NEW process you start.

With 65 installed apps, believe me, it's needed.

Now, you fail to understand the basic issue here.

The way Android works has been there for a long time. It didn't change at all. AT ALL.

Some little things inside changed but the principles are the same since 4.x or maybe even 2.x.

Saying that, now we have a very similar system but with less RAM/worse optimisation IN SOME cases.

Before on 4.2.2 we had very very similar system but with more RAM available.

And now, the UI is smoother. But the apps are as speedy as before, there is no significant increase, anywhere.

Instead, occassionally, the device redraws the homescreen in order to proceed with processes.

I can bet it will happen on each phone in certain memory load. You don't experience that, but it's you.

I think you use the phone in a different way, that's it.

Now let's end this stupid talk. I've used too many different smartphones on Android.
[Xperia Z General] kingvortex:
And you say I'm stubborn....

Not one thing you said there addressed anything that I carefully explained to you.

This time I'm definitely done with you. Anyone reading this thread can plainly see that you're clinging to false beliefs on how things work in Android and refuse to be helped.

Good luck with that.
[Xperia Z General] doministry:

What I dont understand is...why some regions have the eco mode controller and some have the extended one.

Could it be that the customization now for the 4.3 is done a bit deeper now? Like made to suit the phones sold in that region?

If its just mere customization, then why the difference in OS software?
[Xperia Z General] tomitsu:
Strange, I don't have that issue. Maybe there is something wrong with Your Internet connection. Or try cleaning YouTube data and cache

Hi, i'm using C6603 right now in Indonesia with Singapore firmware..

And now i have problem with the network data, even the icon H+ appear ( otherwords, my mobile data is actived ) on my phone but sometimes i can't access anything till I disable mobile data network for a while and reconnect it..

Does the differerent of Indonesia baseband and Singapore makes this problem???

Unused RAM is wasted RAM.

[Xperia Z General] kingvortex:
Guys, if he wants to carry on believing that memory allocation in Android works the same as it did in Windows 98, then let him.

I've tried a few times to explain it to him (in very basic terms that anyone should understand, see page 22 of this thread), but for some reason he absolutely refuses to be educated on the matter and would rather resort to veiled insults questioning people's intelligence in response than admit that he's wrong about it.
[Xperia Z General] kingvortex:
The 'book' is the Android developer documentation and the Linux documentation. I think I'll trust that over some random guy on here that doesn't understand how it works, if you don't mind.

If you think that OEMs are putting more RAM in devices and reducing their margins for it to remain unused, then you're deluded at best. It's there because a Linux/Android system runs better with more RAM. Just not for the reasons that you think.

Very basically -

1. More RAM is more space for (cached) processes, which aids multitasking.

2. More RAM allows a bigger cache, which aids general performance.

Neither of those using up RAM will stop you opening new apps or cause a decrease in performance because less free RAM is available. If RAM is required to open a new app, either some cache will be cleared or a low priority cached process will be killed. There is zero need to leave large amounts of RAM unused 'just in case' you open a new app some time in the future.

This doesn't mean that every last bit of RAM will be used up or that there will only be 2MB free either. There is a limit where Android will start to kill low priority cached processes on it's own, just not an unrealistically large limit.
[Xperia Z General] doministry:
And you clearly show how much free RAM is - to some extent - influencing the device's performance. That's one of the reasons - tje ones you quote - why Sony Xperia occassionally kills the homescreen in the background.

It's hard to say.

I can say my phone on TMobile Poland has 0 problems so far.

But honestly in the past few years I contacted my provider very often regarding problems etc. and I know providers often have problems which take some time to be fixed, or they do some development which causes problems. But it may be your SIM card as well.
[Xperia Z General] kingvortex:
The LMK would never, ever kill a high priority process such as the launcher at the levels you're complaining about (400-500MB free).

I said Android would kill low priority cached processes at _low levels_ of free RAM. It would have to be critically low for the launcher to be killed. That in no way validates your need to see excessive amounts free, even if you want to try and twist it to your own end.

[Xperia Z General] nemer12:
so this is maybe a wierd thing ?

I had 2 Sony Xperia Z.. both with 4.3

The old one = better battery, phone entered DEEP SLEEP, and good overall...

The new one (because I've changed in warranty) = poorer battery with 4.3, it doesn't enter in DEEP SLEEP, when I talk at the phone the connection brakes up and the phone call ends and its very annoying because it happens all the time!

Another question of mine is why when I'm calling someone and talking with them I dont have 3G network, and I can't surf the internet? but only when I talk, now I have 4.2.2 sadly.

[Xperia Z General] LosserKlosser:
I have found that I can kill a lot of wakelock problems simply by unplugging from charger, reboot, enter pin, plug charger in, charge for a minute and unplug charger. I do this every morning now, I forgot to it the other day, I had massive wakelock drain.

Also, I reboot after turning of wifi and GPS.

I get around 5 hours of screen time on this ROM - quite nice.

---------- Post added at 09:24 AM ---------- Previous post was at 09:18 AM ----------

I *THINK* it has gone down a little. Before some calls even on lowest volume would shred my ears, I think the lowest setting is just a little lower than before.
[Xperia Z General] BR4DOKYBrazil:
Exactly!
[Xperia Z General] Koralsky:
I have exactly the same problem with my Xperia Z and smartwatch2. I used to try a couple of different 4.3 firmware (with complete data loss), but the end results was the same.

After that I flashed my old 4.2 firmware and the problem was gone – WiFi and Bluetooth (with connected smartwatch2) worked together like charm.

In the mean time I receive my 4.3 update though PC Companion and, yes, with officially updated 4.3 the problem with my Wi-Fi when the smartwatch2 was connected has return.

This is terrible bug in 4.3 for Xperia Z. Right now I can’t use my smartwatch2 for anything other than to check the time…

I’m not sure if this problem is related just to smartwatch2 or to any other Bluetooth connected device.

MMS

I am unable to send and receive MMS unless my data is turned on, which was not the case before. I have auto MMS enabled on the stock messaging app as well too but they don't come through automatically. I know it's not an issue with my APN because they send fine once I turn data on. Does anybody else have this problem?
[Xperia Z General] HellRoot:
For this you should have two apns... One for data and one for mms.
[Xperia Z General] nyanmar:
Thanks for the reply. Yup, I do have 2 apns. I've never had this problem before on 4.2, I would just be able to send and receive MMS without the need to turn on my data everytime. Are you sending and receiving your MMS just fine without turning the data on 4.3?
[Xperia Z General] LosserKlosser:
Wow, I'm totally confused right now. I didn't think it was possible at all to send MMS without having data turned on.

All I can say is that on my Wildfire S, my I9100 and on my Z, I have never sent MMS without having data turned on.
[Xperia Z General] nyanmar:
Wow really!! I wonder if it's a carrier-related thing, I've used T-Mobile in the past and now using Straight Talk with AT&T (im from the US) and have always been able to send my MMS without the need to turn on data. That's why I was confused when my MMS wasn't sending or receiving automatically!
[Xperia Z General] GROGG88:
Sms requires no data, but MMS should require a data connection to send/receive.
[Xperia Z General] nyanmar:
Yes, i understand MMS requires data but my phone had always downloaded/send my MMS automatically without the need to turn it on manually in the past. I swear I'm not crazy or delusional lol :(

For all of you that turn your data on manually everytime, have you tried checking "MMS auto download" (if you use the stock messaging app)? If so, have you successfully received your MMS without turning your data on ?
[Xperia Z General] LosserKlosser:
I don't have a setting with data disabled other than airplane mode. I have 2G/3G/LTE. And off.

---------- Post added at 11:02 PM ---------- Previous post was at 11:00 PM ----------

So what I'm trying to say is, that my data is always on, so this is a totally new issue for me.
[Xperia Z General] GROGG88:
I always have that setting enabled. It makes no difference. Data must be turned on to send/receive data (mms).
[Xperia Z General] yasasflash:
Mate i'm using the MMS auto download option.

So even though the mobile data is disabled , it automatically gets activated while receiving a MMS.

( Up arrow and down arrow are visible near the signal strength symbol)

NO problem so far with that. MMS receiving automatically even the data is disabled by me. :good:
[Xperia Z General] nyanmar:
Thanks for the reply pal :) May I ask the process of how you updated to 4.3? Are you using a pre-root ROM or did you update via SUS? If the latter, which customization number are you using?

Stamina mode problem

My phone never wakes up from sleep with Stamina mode on. I reinstalled the software and the problem is still there. Everything is normal with Stamina mode turned off. I just can't stand the massive battery drain. 1am - 100% 10am - 85% (standby mode) :(
[Xperia Z General] XperiaZUser.:
Oh thank god I thought I was the only one and was about to send it off for repairs. It's just a software issue then?
[Xperia Z General] zeljonsu:
yes... hopefully it's just a bug and I guess Sony will soon release a maintenance update to squash these terrible bugs.... :)

UPDATE: I already e-mailed Sony Mobile about this issue. Hoping for a speedy reply and solution. :)
[Xperia Z General] XperiaZUser.:
Could you try something?

Put the phone in your pocket and press the power button then take the phone out of your pocket. For me the screen doesn't turn on, I don't know if it's a feature or a bug but if it's a feature it just seems like it's too sensitive and causes the screen not to turn on when it should.
[Xperia Z General] gerickjohn:
As I've said before.. Stamina Mode enables a sort of "Pocket-Wake protection" where the proximity sensor will disable the power button when it is triggered..

[Xperia Z General] zeljonsu:
OH! now I know how to solve the problem... it's because of the screen protector that I'm using.... currently using a Spigen Glas.T. but I got the first edition so I got proximity sensor issue.... thanks for the help! I guess I should take the screen protector off my phone.... :(
[Xperia Z General] heavybass:
I have the same problem. Additionally I get after some hours without reboot black screens: The page loads, but nothing is displayed - only a black screen. When this happens and I close all tabs, the "Chrome" icon also disappeared. To remove these issues I have to delete the Chrome cache (reboot doesnt help).

Another issue I have with the latest update is that the battery save mode doesnt work anymore. Its turned on, but it doesnt turn off mobile data, if the battery drops below 30%.
[Xperia Z General] boyq:
I also experienced black display in chrome when page is loading. I had to refresh a lot. Sometimes pinch-to-zoom in & out as well as scroll-up & down doesn't work upon accessing a webpage which is a bit annoying.

Multitasking seems to make the phone lag a lot that the icons in launcher are refreshing.

Anyone using skype? I get a lot if force close well ever since 4.2.2.. I guess it's on skype's end and not Sony's that's buggy?

I do not share this problem. When using Wifi the bluetooth handles easily both the smartmatch 2 and the BT-adapter for streaming walkman content via Throw. Tried about 2 hours without any issues with BT or wifi.

I only had some issues with the Xposed framework. I had to reinstall and boot twice before everything worked again.

For upgrading I used the process as described in this thread without deodexing. Would be interesting to know which method were used by the users experiencing the bluetooth/SW2 bug.
