I've made a clean install of the latest Foxhound ROM and have been using it for almost a week now, i have noticed that while playing 3D games [Carnivore hunter and AnDrone Simulator] for minutes my phone gets hotter than the usual... The previous builds of the rom did not have that issue... I just would like to know if some of you guys are experiencing the same thing...

Also most of the time I get an FC on com.google.process.gapps i searched for possible solutions for the fc using the forums, and i did clear data and cache on all google apps on the phone but still getting the error.

Any thoughts on this guys?..

Hi all,

Is there anyone who has tried both 2.1 and 2.3? I only got my x10 a few months ago so it came with 2.3 already on it, and i don't want to lose all my data my downgrading it to 2.1 just to find out it's crap.

So are there any massive differences, is it worth trying 2.1 or is 2.3 better?

Also i read about a unofficial camera fix for 2.1, if anyone has anymore information about that?

AW: [Q] 2.1 vs 2.3

why should you go to an older version if your statisfied with your current? I must say i didnt try 2.1 (only 2.3, 4.0 and 4.1) and 2.3 was best, so i returned. little tip: cm7 (by m&m or zidhzu) has awesome performance or try dixperia 7 it is beautiful and the best stockbased rom i had.

[XPERIA X10 Q&A, Help & Troubleshooting] jakuburban:
I have used both of them. I must say 2.1 is much faster then 2.3 (official versions). Also You must consider that there's no clear way of moving apps to sdcard (of course there are apps for that) and also You have to think about apps. Most of the apps are written 2.3+ or even 4.0+ so some of them might not work.

I think always the best ROMs were 2.2.
[XPERIA X10 Q&A, Help & Troubleshooting] LegibleEel:
Sorry but I have to disagree with your decision. 2.3 is much better on terms of performance and speed. Coming from someone who got my x10 stock with 1.6 donut. 2.1 was awefull IMO.

Anyway, @op just flash a custom ROM, they are far better than stock will ever be ^^

[XPERIA X10 Q&A, Help & Troubleshooting] keenofhiphop:
AW: [Q] 2.1 vs 2.3

I always prefer dixperia, it was my first rom and so i cant give an objective review. It felt better than Dixperia 8 stock based/ Sstyle (that i tried directly after) and very clean and as a great contrast to stock. M&M had a "rocksolid" feeling, it was the first cm rom and really good performance. As stupid as i was as noob i choose the wrong baseband (.67) in aroma and i didnt have fun for long... :D

I suggest you, if you love feelin and theming of cyanogenmod of course the cm rom, if you like the sony xperia s- style and a fully working camera then head for dixperia 7 (stockbased rom-> best camera).

I am at Dixperia 8 Gaming and i will probably stay at it, it is really worth it! You have to become Premium User to get it but it is really the best rom I ever had.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] NotLikeThis:
Apologies in advance for the newbieness of this question. I have scanned the forums for an answer to no avail.

I have a Samsung Galaxy S3 LTE - i9305. It was on the UK Orange network and my only reason for rooting and flashing it was to use it on the UK Vodafone network. I assumed that the only thing I would need to do was put a Vodafone stock ROM on it and bob's your uncle it would work.

I rooted with CF Auto root and installed Samsung-Updates.com-GT-I9305-VOD-I9305XXBMA3-1357552475. Which is the ROM used in the Vodafone/JB version of the phone replacing the original Orange ROM. Popped in my Voda SIM and it still prompts me for the SIM Network unlocking code.

What am I missing here? I assumed that wiping the Orange ROM and replacing it with the Vodafone ROM would allow the phone to accept my Vodafone SIM.

Any help appreciated.

Thanks for the prompt replies guys. Very much appreciated. Not sure how I didn't find this previously as it seems like a key step in the process! I think I will need to flash the original ROM back as suggested by kanzi83 as I don't have that menu option 4. NW LOCK NV DATA INITIALLIZ. I only see the first three menu items. Wish I had backed it up before I installed the new ROM but I am downloading the original as we speak and will flash it and re-try this process. I'll update here if that works.

Success

Sadly I had already flashed back to the original ROM before reading this but I can report that flashing the original ROM did the trick and the menus appeared as described above and the process worked, my Vodafone SIM is now accepted by the phone (even with the Orange\EE ROM).

So a fantastic result many thanks all for the help. I am left with a curiosity question so no obligation to answer but - is that procedure all I ever needed to do to allow my phone to accept any SIM? - OR would it not have worked if I hadn't rooted it first? It's just it seems so straightforward and I always see people on the forums asking for 'unlock codes' etc and there seems a lively business in selling these codes online but if all that is required is following the above process to accomplish the same thing why would anyone pay for a code?

And a parting shot - Respect to the XDA community, seems like a committed and smart bunch of people putting their skills out their to help us all, without the preaching or patronising you see on other sites.

[Sony Xperia T, TL, TX, V] asterixmic:
Hi,

I just bought my Xperia T in Romania.

Operator: Orange

The software version was 4.0.4 Central Europe.

When the phone is on 3G network , even if it shows full signal, the calls do not go through.

I have to wait few minutes or restart phone!

Sometimes is works, sometimes it does not.

Also who is calling me says that the my phone is disconnected.

This does not happen on 2G network.

What is the problem?

Operator related or should I take it to warranty?

I changed from HTC Desire and did not have this problem.

Also I tried the JB update and the same problem

[Sony Xperia T, TL, TX, V] asterixmic:

I was hoping that someone else had this problem and maybe related to radio version (used with my previous Desire).

But I see that there are no radio versions for Sony. Just baseband which I understand is embedded in ROM.

Oh well... two more weeks with my broken screen Desire till I will get this one back :(
[Sony Xperia T, TL, TX, V] asterixmic:
So, after two frustrating weeks and sending the device to service and getting a response "defect not confirmed,

I went to the service explained them and FINALLY they understood :)

They replaced the motherboard in half hour and left happy from the service center.

BUT, as I was in the car discovered that there was no google apps, no way to input google account, etc. and the software version was the first one for LT30p.

As I did not want to go back I got home and hoped that a PC Companion update will solve the issue.

But surprise, it said that there is no update :(

So I installed the JB FTF and the 3G problems again :(

I also tried more Stock FTF and the same problem :(

So my question: might there be a problem that the FTF I have been using are for LT30a (which is for 4G)

Is this possible?

I even tried unlocking the bootloader and EMMA only shows .195

Any ideas because I don't want to get it back to the service.

I am starting to think that this might be a LT30p vs LT30a software.

Does anyone know how I could see what are the official firmwares for my phone?!

Is there a way to get my hand on a user/password for EMMA ?

Thanks
[Sony Xperia T, TL, TX, V] smardu:
You are telling us that you are using a firmware which is designed for LT30a on a LT30p?

The baseband is different for sure.

You can flash JB version for LT30p with FlashTool.

Im using the same LT30p on orange ro and had no problems.
[Sony Xperia T, TL, TX, V] asterixmic:
No

I was just wondering if maybe there is Sony issue because if i go to sony support website it only shows Xperia T (LT30a).

Maybe there is a problem with how I upgraded to JB.

[Xperia Play Q&A, Help & Troubleshooting] CosmicDan:
I used to mess wit this on the X10, and did find better values. But for the Xperia Play, at least on CM10, any extra or changed flags either causes worse performance or FC's.

The defaults I use are:

dalvik.vm.dexopt-flags=m=y

Which means "Map registration = yes" (this should always be on) and everything else at default (what the ROM wants to do).

90% of what you need to know (and what is safe to experiment with) can be found in the DalvikVM documentation. Give it a good read.
[Xperia Play Q&A, Help & Troubleshooting] sdojoin:
Re: [Q][Disqus] "Dalvik.vm.dexopt-flag=???" - What are the best for performence

Thanks.;) But i was wondering if mybe we can "force" the system/rom to optimize the dalvik.vm each time we use it.

Example;

dalvik.vm.dexopt-flag=o=y,m=y(optimize=yes, register map=yes)

Or

dalvik.vm.dexopt-flag=o=v,m=y(optimize=verify,register map=yes)

Will it make any diff?? I know it'll use more ram than usual, but will it increase performence??;)

Regards,

Sdojoin
[Xperia Play Q&A, Help & Troubleshooting] CosmicDan:
o=v (-Xdexopt:verified) is the default, as is v=a (-Xverify:all). This means that only opts that are verified will be optimized (cached to dex files). Unverified code will not be optimized.

Disabling verification will make dalvik-generation faster, but it is less safe and also 0% faster once the dalvik-cache is generated. Apparently it has the possibility of decreasing RAM usage at the expense of higher IO or CPU cycles (which wouldn't be bad, since RAM is the main limiting hardware on Xperia 2011 devices) but I never noticed any difference.

The only real change you can make there is o=a, which means that it will optimize *all* dalvik opts - even those that fail verification. In the case of custom ROM's, this usually results in constant FC's and even reboots - and can even make the system slower because some classes are intentionally made to fail verification when, in the development process that they were found to have overhead in dalvik-cache reading making the unverified cache slower than just reading reading the dalvik (compiled Java code) directly. This is usually the case with simple Java methods that are heavily dynamic and rarely used (e.g. on a service startup).

Another option can be v=n o=a which means to verify nothing and optimize everything (potentially the fastest but also unsafest).

With all this said, I have not tried messing with these things since Gingerbread. All I can say is, experiment with these flags. Measure the size of dalvik-cache, the time it takes to generate, and the time it takes to load a large dalvik app (look for an app/game that has a very large DEX file in dalvik-cache, measure different parts of the app/game loading sections since some parts might be native instead of dalvik/java).

Re: [Q][Disqus] "Dalvik.vm.dexopt-flag=???" - What are the best for performence

In-conclusion, "it can increase our perf & decrease it at the same time.". Erm...

dalvik.vm.dexopt-flag=m=o=y(map registration=Xdexopt=yes)

[Xperia Play Q&A, Help & Troubleshooting] CosmicDan:
Well that first link I posted explains pretty much everything about the dalvik flags, and that thread I posted last is a good experiment for learning purposes. If it doesn't make sense I guess you need to know more about the Android technicals. But really, I think you can't wrap your head around it for one simple reason - there is no magical dalvik setting that will make the device faster. There is no "hidden setting" or "something Sony/FXP forgot to try" - the dalvik settings are fine, and while changing them may slightly increase performance in *some* cases, it will almost always reduce reliable and performance in other cases.

About dalvik heapsize:

In summary - heapsize = memory an app can consume before Android starts cleaning/pruning the app's memory for data that isn't in use. Lowering it to e.g. 40m can increase performance a bit but some games fail to load (because the OS starts GC when the app has not finished using the heap it requires; and also because so many game developers out there are lazy and don't do threaded asset loading properly)

Ther is one thing i don't understand: the default values of the Nexus 7 are:

dalvik.vm.heapstartsize=8m

dalvik.vm.heapgrowthlimit=64m

dalvik.vm.heapsize=384m

Especially the heapsize seems to be very high.

The defauklt settings of my Galaxy Note with CM10.1 are:

dalvik.vm.heapstartsize=8m

dalvik.vm.heapgrowthlimit=48m

dalvik.vm.heapsize=128m

So they are much lower values. Bothe devices have 1Gb of Ram. :confused:

Some people say higher=better, some say lower=better and I'm really confused now.

What are the "perfect" values for the Galaxy note (1GB Ram) or Note 2 (2GB Ram) ?

[Xperia Play Q&A, Help & Troubleshooting] sewer56lol:
There never exist "perfect values for dalvik".

It is how you want to allocate memory.

1. VM Heap Size is max Memory per one ram heal that can be given to an app.

2. Heapstartsize is the minimum size for a dalvik ram heap.

3. HeapGrowthLimit is a value for "normal" VM heaps, I reccomend setting VM heap size large and then HeapGrowthLimit at a good value.

[Xperia Play Q&A, Help & Troubleshooting] CosmicDan:
No it's not. All the heapsize parameters are to do with GC, they have nothing to do with "how much memory" dalvik tasks will use but determine barriers/zones for garbage collection.

Besides, if you read the therad you'd see that this has nothing to do with what we're talking about. We're talking on *flags*, heap parameters should NEVER be changed and will only make device unreliable.

EDIT: Read documentation before repeating what others say on the internet - http://show.docjava.com/posterous/file/2012/12/10222640-The_Dalvik_Virtual_Machine.pdf

Hmm fair enough. Well I've only ever seen m=y on any ROM, stock or custom or otherwise (as long as it hasn't been screwed up by some idiot chef). So maybe it's just a case as most so-called tweaks - what it comes with is what it's designed to work with.

Perhaps with the Qualcomm-accelerated Dalvik blobs (I posted it a while back, check my threads) there will be different results.
