[Sony Xperia S, Acro S, Ion] supermeerkat:
Yeah, I'm currently trying to discover a new unbricking technique - wish me luck!

I've learned a couple of things from this experience:

removing the battery in the xperia s is surprisingly simple

the back cover is held on by a random mix of both torx and "+" shaped screws

the torx screws are T5 sized, not T6 as stated on the xperiablog disassembly guide

the design of the 3.5mm audio jack is quite cool - the actual jack is attached to the phone's back cover and is not soldered to the main board. Instead, a set of copper 'legs' on the jack touch some contact points on the PCB. This means that the stresses from a set of earphones (e.g. accidentally tugging on the cord) will not rip solder joints from the PCB :good: Not sure if other phones or media players have this design but I like it.

my phone is still bricked

I took a voltage reading of the battery and it was down to 3.5v (nominal voltage is 3.7v, max is usually around 4.2v) so maybe this is why it can't enter flashmode or fastboot. I found that when the phone is on a charger and spends a few hours with the red light on followed by a few hours with the red light off, it's actually just doing endless charge/discharge cycles. However, it never reaches anywhere near a decent voltage and this might be why the 'rubber band' trick didn't work.

Right now its charging with the red led off and its at 3.4v. I'm too afraid to leave the phone charging while I'm out the house so I've not been able to continuously charge it for more than 12 hrs at a time. Maybe after a few days it'll eventually get back up to 4.2v?

I got a mad idea when I noticed the battery terminals in a few of my older sony phones were the same, except the polarity is reversed. So I took a fully charged battery from a W995, flipped it round so the polarity was correct and forced it to make contact with the battery terminals....and nothing! Still no fastboot, flashmode or anything. Tried the same thing using a battery from an xperia ray and again, nothing happened.

I'm all out of ideas, I might phone sony and try asking for a quote. I'm so annoyed at this, the phone itself is in immaculate condition. Can't justify buying another smartphone, I've returned to the stone age and I still find myself trying to tap the icons on a non-touchsreen phone :(
[Sony Xperia S, Acro S, Ion] entermetallica:
The battery from three W995 probably doesn't have enough power to run the phone. Just keep trying and see what you come up with.
[Sony Xperia S, Acro S, Ion] wxl104:
I am noob here,but my kindle fire has the similar things happen like this,Just has little battery the kindle fire can't start,just when the charge all finish ,it can start once,if I didn't others like flash a rom,or just wipe my kindle,after finish I reset,it can't be start,so I start the kindle,let the battery all finish,and then go on charge,when the charge full finish,it can start again,so I have only one time to flash the correct rom,or something after all battery off,and charge full.So I think if you have the same problem like this,if so,just press start button,do nothing to your phone,untill the battery finish(the big point is the battery must run down),and then charge,after full charge go to fastmod to flash what you want,or I think you can just flash stock onto your device.
[Sony Xperia S, Acro S, Ion] supermeerkat:
I thought about buying a replacement battery just to get enough juice to start the phone, but there's no guarantee that it will arrive fully charged and the phone might just drain the new battery anyway without allowing it to enter flashmode!

I have tried charging the battery as much as possible and taking it out the phone for a few hours, then putting it back in while immediately trying flashmode and still no luck.

Last night I phoned sony to ask how much it would cost for a repair. Unfortunately, the nice lady I spoke to didn't understand what a bootloader, kernel or ROM was and just said that sony can't touch the phone if the software's been modified :confused:
[Sony Xperia S, Acro S, Ion] wxl104:
if you buyed a replaced batterey, you dont you charge full it and then put into your phone and flash the stock? Try this,and dont forget installing the driver for your phone into your pc
[Sony Xperia S, Acro S, Ion] supermeerkat:
I'm not sure a replacement battery will let the phone enter flashmode, I mentioned earlier that I tried various spare sony ericsson batteries (same voltage rating, but fully charged) and the phone still did nothing :(

I think I'm either going to sell the phone on ebay as faulty and perhaps get a new phone after that....or I could buy a faulty xperia s from ebay (with superficial faults like touchscreen damage) and do a motherboard swap.

Edit: I've managed to fully charge the battery using a borrowed phone, confirmed it was over 4v with a voltmeter, but still no flashmode :(
[Galaxy S 5 Q&A, Help & Troubleshooting] subcola:
So I am interested what do you think. Is 2gb of ram enough to avoid any lagg?
[Galaxy S 5 Q&A, Help & Troubleshooting] ewa12321:
For average smartphone user like my mom, father or my brother yes. Its more than enough. My mother has LWP, some widgets, almost all stock even Samsung launcher. she's using phone for texting, learning, web browsing... in her phone she has only 768mb RAM on phone alavaible, 200-300 free no lag. She is happy. But who someone who like to have TONS of widgets, launchers and other heavy apps somentimes I see small lag like 2 seconds. But I downloaded like 350-400 apps/games lots is running in background. So lag is my/bad apps fault, im sure of this. When I unistall those most RAM hungry I have 800 RAM free.

Time to delete some apps. I dont need 4 app monitors, 5 file organisers and so ;)

Hrm, the question isn't really 'is it okay today' because it's kind of okay right now, but in 12 months will it still be ok? I mean, if we're throwing a huge amount of cash dollars at this phone is it going to last 2 years?

I'd foresee no. Apps aren't lightweight anymore and their coders are exploiting the growth in power in the phones. I think in 12 months there will be some frustrating times making you wonder why they saved $4 a phone at manufacturing. And we know the answer is simple. If the phone was amazing, they wouldn't get away with 12 month new releases.
[Galaxy S 5 Q&A, Help & Troubleshooting] dandroid13:
Same here, TW doesn't lag at all when not loaded with 300+ apps, but some people still live in 2011. :p
[Galaxy S 5 Q&A, Help & Troubleshooting] RaptorMD:
Lets see I had the GS3, GS4, GN2 and GN3 and of those devices only 1 had 3GB of RAM and ALL worked just fine for me. So to answer the 2GB of RAM issue you will be just fine. KitKat 4.4.2 is even more optimized and runs even better on lower RAM devices. About 18 months ago we only saw 1GB of RAM on devices and now we have 2-3GB of RAM so I don't see a problem.
[Galaxy S 5 Q&A, Help & Troubleshooting] karmuh:
No idea why people would have hundreds of apps on their devices. For me, I probably have 40-50 apps installed at any given time...and that's being pretty generous. 2GB will be more than enough for me.
[Galaxy S 5 Q&A, Help & Troubleshooting] degast:
This is kind of a trivial question. First there's the philosophy of trying to utilise as little RAM as possible, thus being efficient on both RAM and battery. Secondly there's the hunt for specs; we all want more and more RAM, more and more milliamps on that battery. That makes sense, more = better, but when you combine these 2 things, there is a limit on both. I don't even use 3GB of RAM on my pc (have 4). Not even photoshop uses that much (unless you are some crazy artist - but then you'd be using a workstation with 64GB of RAM).

TL;DR: 2GB will be enough until phones become desktop replacements.
[Galaxy S 5 Q&A, Help & Troubleshooting] GuestX0057:
RAM isn't the biggest reason why TW lags - the Note 3 has 3 gigs and it still has hiccups even when there's plenty of RAM available. TouchWiz is a horrible human creation that apart from a few aspects should not even exist. Sonys, HTCs and even LGs modern smartphones are virtually lag free even though they have their own skins just like Samsung.

So to answer the OPs question, no I don't think 2 or even 22 gigs of RAM would make the SGS5 lag free.
[Galaxy S 5 Q&A, Help & Troubleshooting] xeizo:
You do know that it is Android 4.4.2 and a totally new Touch Wiz version, you can say nothing about how it performs before you have tested it unless you actually are psychic! :D
[Galaxy S 5 Q&A, Help & Troubleshooting] GuestX0057:
You are right about this. Based on Samsungs (or rather TouchWiz) track record I don't have high expectations though. I also seriously doubt they have completely rewritten TW, they have just changed some of the looks in it. And my point still stands - modern smartphones with modern processors and a relatively good amount of RAM should run Android fine without lag. If competition can do it, so can Samsung. If they lag with the same hardware that competition doesn't lag with, then there is something different in the software that differs from competitors e.g. skins, launchers etc.
[Galaxy S 5 Q&A, Help & Troubleshooting] frankgreimes:
Can't answer that yet nobody knows how the new TW will perform. One thing is for sure I will always replace the standard UI with either Apex or Nova Launcher.

I'm only using important apps because a smartphone to me is still a phone, so I hardly have any games, widgets or all that stuff installed but having said that more RAM can never be a bad thing, nobody knows what the future holds. When it comes down to more and more multitasking 3 GB should provide a smoother experience despite all the optimization.
[Galaxy S 5 Q&A, Help & Troubleshooting] RaptorMD:
I have owned the Galaxy S3, S4, Galaxy Note 2 and Galaxy Note 3 and while I experience some lag on the S3 and Note 2, I didn't notice anything major on the S4 or Note 3 and maybe its just me, how I use it or I missed it. I think Samsung continues to improve on their UI and unless we ditch them as an OEM we are stuck with it. I do wish they would go stock Android like they do on the GPE and just put their added apps into it but that won't ever happen.

I have chosen my next phone and pre-ordered my accessories, the Galaxy S5 is what I will be getting, I like what Samsung does, what they offer and ultimately I am happy with their gear.
[Galaxy S 5 Q&A, Help & Troubleshooting] JoeFCaputo113:
Just updated my Sprint S4 to 4.4.2 and there is no lag at all 110 apps installed. Blazing fast, looking forward to the same in the S5 :)
[Galaxy S 5 Q&A, Help & Troubleshooting] subcola:
Nice to hear. So I am buying s5 instead of z2 becouse I hate sony's design.
[Galaxy S 5 Q&A, Help & Troubleshooting] RaptorMD:
Most of the phones today come with 2GB of RAM, the phablets come with 3GB perhaps due to the larger screen, more likely to have multiple windows open (dual apps) not sure why we the S5 doesn't have it. The G3 is supposed to have a 2k display which again is just a specs war thing. A 2k display is useless and unnecessary on a 5-6" display because it will require a much bigger battery just to match what it got last year.
[Galaxy S 5 Q&A, Help & Troubleshooting] GuestX0057:
I saw an interview last fall from one of the manufacturers considering 2k screens and he said that they abandoned it at the time because the resolution difference resulted in a whopping 60% more battery consumption compared to a full HD screen.

I'll use the LG G2 as an example because it was considered quite long lasting. It had 3000 mAh, and to compare the G3 would need 4800. I'll repeat myself, 4800 mAh just to be on par with the G2. How many of you honestly think that's going to happen anytime soon? Even the massive phablets don't sport batterys even close to that capacity.
[Galaxy S 5 Q&A, Help & Troubleshooting] RaptorMD:
Well said. For me 1080p displays on a 5-6" screen work just fine for me, nothing against higher res dislays but lets not put them there for specs sake, do it because they offer something.

I will get the GS5 now and wait to see what the GN4 looks like in the fall and trade up or wait for the GS6 and trade up then.
[Galaxy S 5 Q&A, Help & Troubleshooting] barondebxl:
Plus 1, 2k is overkill, way overkill. But smartphone displays can still improve at 1080p. For example Sony can have better viewing angles and colors, Samsung could use better whites... Things like that otherwise 1080p is great.
[Galaxy S 5 Q&A, Help & Troubleshooting] Caelrie:
I don't know what the point of lying is. Why do it? The GS3 is infamous for being laggy becuse of touchwiz. Mine was no different. For you to say there was none on yours is simply a falsehood.

The Gs3 didn't lag for me AT ALL. The S4 however did a lot.

Im kinda disappointed with all the new tab pro series ( the software seems very ****ing laggy )

thank u Samsung for ruining Android 4.4 -_- , so i think S5 wont be any better :(

http://www.youtube.com/watch?v=-UleBq5pVHI&list=UUO_vmeInQm5Z6dEZ6R5Kk0A ( 10.1 using Exynos 5420 )

http://www.youtube.com/watch?v=v1IxIMIDKT4&list=UUO_vmeInQm5Z6dEZ6R5Kk0A ( 8.4 using Snapdragon 800 )

the funny thing Samsung seems going worse with every newer flagship : S2 was one of the fastest Android device ever -> S3 Was kinda fast with some lag here and there -> S4 it was so dam laggy and it stuttered like a single core device from 2010 ( its kinda fixed with updates tho ) -> S5 i bet it will be even worse than S4 :eek:

Samsung dev team need to be fired asap ( specially the tab team )

i bet Samsung can make an core I7 extreme to lag :rolleyes:

And probably 2GB wont be enough even with Android 4.4

2gb is enough with fastest cpu, it seems not a problem.

[MENTION=4331268]yahyoh[/MENTION]:

In Samsungs defense though the 8.4 tablet is powering a 2560 by 1600 screen, which is quite some degree harder to push than a 1920*1080 even with the Krait 400/Adreno 330 combination.

The S5 is now only playing catch up in the market as far as I can tell. You can see how Samsung went from leading specs (S2) to catching up (S3) to somewhat leading again (S4) and now catching up with the same stuff (see G2 or Gnote vs GS5)

2GB ram should do well today, but remember the days when people said 1GB was heaps even though the software developers were developing knowing the ram limitations and restricted app functionality as a result. Now apps consume much more ram than they did before.

RAM is the bottleneck of the S5 and there is absolutely no reason for anyone with a 2GB ram device to get the GS5 (3 GB RAM devices would make much more sense.) You can have the fastest CPU in the world but if your work gets flushed away due to insufficient ram there is no point.
[Galaxy S 5 Q&A, Help & Troubleshooting] polish_pat:
Talk for youself, I like touchwiz, it shows Samsung's experience compared to other OEMs. It might not be the fanciest design out there, but it's by far the most featureful and actually useful comapred to any HTC, LG or other non-vanilla android.

And yes OP, 2GBs is more than enough, I have a note 3 right now and barely go over 2gbs anyways, and also kit kat is optimized to use ram more efficiently. It's actually a goos thing to have your ram used up at 80%, it shows your phone is caching a lot of data for fetching later on. If Samsung didntthink 2GBs was not enough, they would of put 3GBs, but they saw on the Note 3 and S4 how 4.4 play nice with ram.

---------- Post added at 08:49 PM ---------- Previous post was at 08:43 PM ----------

You obviously have great understanding of RAM utilization. NOT

You have no idea what you're talking about and it shows how desperate you are to integrate the conversation. It's not because Samsung kept 2GB in their sub-Note flagship that they are playing catch-up, they just realized how KK is light in RAM use and didnt see any point to putting 3GBs or even 4 until at least android itself is coded in 64bit. You can see by the clear example that ram has nothing to do with performance, nor is the CPU or GPU. The iPhone 5s is basically, on paper Galaxy S 2 caliber with their dual core 1.3ghz cpu and 1gb of ram, and thus, is much smoother and perfroms better in benchmarks than almost any Quad or Octa core phone with top tier GPU and 3GBs of ram.

It's about using hardware correctly. Unfortunately, even though I think android is the best OS, iOS is actually the one that uses the hardware most efficiently. In order to overcome the lag that has plagued all versions of android, not only the ones with skins, they had to overpower the hardware to overcome the lack of utilization of ressources. Project roadrunner, project butter have been googles efforts to fix those issues and i think they still didn't bring it to iOS standards. Kit Kat has been the first version of Android to prove that this problem can be fixed without recoding the entire Dalvik system or switching bases completely. Android phone are huge overkills in hardware. People have gotten so used to spec wars they forgot the basis has to be stronger than the roof in order to make things work. Thisnis mainly the reasons why Samsung has invested into tizen and why they got the Open Handset Alliance to partner with them. Its not because you have a 600 horsepower V8 that you cant be beat by a 200hp honda civic thats tune incredibly well.
[Galaxy S 5 Q&A, Help & Troubleshooting] :
Features don't always mean the same thing as useful because they are subjective. Stuff that someone considers useful or even important are a waste of space for another. When I open the quick settings introduced in Jellybean, I want to see the 6-9 most important toggles - not 25 out of which I will literally never even touch half. And yes I was talking about my own opinion after owning several different Samsung devices ever since the Galaxy S1. They have all had these odd hiccups or lag when the other manufacturers counterparts are smooth with similar hardware. It simply has to be software and that is why I am still sceptical. I might still end up getting the S5 for the other good stuff that it brings, I just don't believe in TW, that's all :)

Exactly, RAM just defines how much stuff you can have open in the background. The CPU does deal with performance though but in modern smartphones the CPU power only really shows in benchmarks that I don't believe in and heavy gaming. Aside from that you are correct, the way Android is built is what causes it to seem slow and not the hardware. But stock Android has been extremely smooth ever since Jellybean - and manufacturer additions have still bogged down phones with good hardware until recently so the hardware has become good enough to sustain the operating system.
[Galaxy S 5 Q&A, Help & Troubleshooting] ballsofsteel:
To say the iPhone 5s is Galaxy S2 caliber is completely wrong. The iPhone 5s multi-tasks in a completely different way than android phones as you probably know, and the A7 CPU? It's crushing the S600 and up right there with the S800. You say the exynos 4210 dual does the same?

Project roadrunner? Do you even know if it exists? I think you probably meant project svelte. Please do your research properly.

My 2GB ram device multi-tasks better than a 1GB device. What makes you think that a 3GB one won't multi-task better than a 2GB one?

I use up 70% of the 8GB ram consistently on my PC because chrome is such a ram hog. So does Dropbox, Google drive. I can open up 10 tabs on my laptop without a hang and come back 3 hours later on the same page. Perhaps not the most realistic use of a phone (but far from unimaginable) can you do the same with a phone with 2 GB RAM?

You can argue that up to a certain threshold more ram does no extra benefit to the user (such as if I upgrade my system to 16 GB, it will yield no benefit to the 8GB configuration I have). However, I can still find ways to use up the 2GB.
[Galaxy S 5 Q&A, Help & Troubleshooting] xeizo:
You can't compare to a laptop running Windows, Windows is a RAM-eater De Luxe and partly by design as it caches as much as it can.

My 16GB RAM in my Windows box gets filled up almost immediately. On the other hand, when I´m running Linux on the same box, or on my 8GB box, I have a hard time using up 2GB even on heavy webbrowsing with lots of tabs(but I prefer Firefox).

Heck, when I'm compiling Android and doing heavy browsing at the same time it maxes out at 4GB RAM! To use all 8GB or 16GB would require like compiling multiple projects simultaneously while browsing and doing heavy image editing at the same time. Linux is MUCH more efficient than Windows, and Android is built on Linux ....

You would need a lot of RAM if you should like to virtualize Windows on your Android-phone though :p
