[Q] Xperia S freezes randomly

Hi everyone.
I'm having a little problem with my Xperia S, it's kind of new (2 weeks of use).
When I'm using normally the cellphone, everything works great, but if don't use it for a long time and I grab it faster and unlocked it, sometimes the cellphone freezes! Well, not exactly freezing, it still works but VERY slowly, almost like freezing. I can't turn it off with power button, I had to user Power + Volume button to turn it off/restart it.
That happened in first week, so I unlocked bootloader and flash it another kernel (advanced stock kernel), and the problem was there.
Later I made a backup of the firmware (I updated to its last version with PC Companion, ICS btw) and flashed a custom ROM (XTXperience 4), and the problem was still there.
Yesterday I flashed a Generic ICS ROM downloaded from XDA Server using Flashtool, everything went normal until today, when the problem happened again.
I've been searching here in XDA and Google and still nothing seems clear of what is causing the problem, if it's the sim card or maybe a hardware problem. I'm going to relock the bootloader today, and I will try to repair the phone using SUS.
What is causing the cellphone to freeze? Hope someone help me with this. Thanks in advance!
btw, sorry about my english, hope you understand most of what I wrote

Well in my experience,
The phone freezes because it is too hot,
Or the RAM memory suddenly drops.
I mean sudden ur phone's RAM memory is 0.
I'm not sure too.
But I think reflashing the kernel, or flash other kernel will fix the problem
Try it

What ics firmware did you flash? And did you do a complete wipe when flashing?

I've flashed other kernel and yes, I do a complete wipe when I flash another ROM, via Flashtool or CWM.
I've been thinking of rolling back to GB to see what happens.
Yesterday my phone freezes like 2 or 3 times in less than 15 minutes. First time I reboot the phone and it was ok like 5 minutes, then it freezes. I reboot again the phone and happened again.
Its not even hot or using a lot of RAM, it always has like 250 or 200mb free

Did u play with CPU settings?

No, this is happening since the first boot of the phone. When I turned it on the first time it happened, and I had to search how to force a reboot because I didn't know how to do it LOL
It doesn't happen very often, but when it does is very frustrating!

Try flashing a new rom, but wipe the system partition too? I always do that to ensure a fully clean install.

I'm thinking in flashing a non based stock rom, like CM or MIUI, because I flashed XTXperience before and the freezing happened.
Oh, and the problem still exists. I believe Wi-Fi connection maybe it's the problem, I'm testing some things right now.

Had this too using Supercharger (by zep) but after few setting it's gone. Maybe you should try to run the script ?
It was with stock rom and advanced kernel v15/16.L

Well, I was on 6.1.A.2.45, I relocked the bootloader and an update changed the firmware to 6.1.A.2.55 using SUS without wiping data and the problem was still there, so I repaired the phone with SUS, it erased everything and the problem was gone for like 2 days. Today it happened again.

Advanced Stock Kernel supports 6.1.A.2.55 firmware?

Well, I Supercharged my ROM now, which setting do you use to fix the problem? I'm still having it.
I even flashed a CM10 based ROM and its still happening! I think it's a hardware problem

Xperia U malfunction after 6.1.1.B.1.54

Hi,
I´m from Portugal and since December i have a Xperia U (Optimus operator), stock ROM was 2.3.7. After 2 weeks i update using Pc Companion to ICS (release 6.1.1.B.1.54 ). I notice some delay in response, no big deal, i was satisfied with it. But after about 10 days or so, it start freezing aplications, and some errors messages. After it when i want to use the phone it only shows a screen saying that only emergency calls allowed". Werd, i take out the battery teh SIM, and the same problema, can use at all the phone. Take it to the warranty, they reset the factory settings, and install again the 2.3.7. Phone is fine, the first day i have aftaer the warranty i install the ICS using the PC companion (official release from Sony) again. Guess what 3 days later the same problem. They restore again the phone with 2.3.7 an till now, after 2 or 3 weeks the phone is fine.
I´m thinking Sony made a bad job with ICS to the Xperia U. What you guys think about it? Do you think i can install a custom ROM or other rOM from Sony? I don´nt now if there are others to my phone. Wich custom ROMS can i use?
Thanks guys for the help, and sorry about my English.

Random Reboots

Hi Everyone! I have a very annoying problem with Reboots.
I have Xperia ZL 6506, Bought a week ago.
I have Jelly Bean 4.2.2 (with latest firmware) - http://forum.xda-developers.com/showthread.php?t=2459497
. But it makes no difference, because I tried 4.3. too and it didn't make any difference.
Tried Full Wipe! Tried ,422 and 2.67 firmware versions.
I had an Xperia arc S, and it went well with that, so I tried to install Custom Rom on Xperia ZL too.
Made my phone Root.
I tried everything, till I flashed the ROM and it gave me Random reboots.
Now I am on Stock Firmware, ROOTED, Bootloader Locked and having Random reboots (with no link to why it happens).
Wi-fi isn't guilty, because it happens with on and off Wi-fi Too.
One more, I tried repairing it with Sony PC studio, but it gives me "Sony Update Engine Failure (Error 1601). "
Please help me. I am sitting about 7hours and have found no solutions for me! I have an SD Card 16 GB (Came with the phone) - Tried to format it many times and nothing changed maybe Internal card is the problem?

Many have had this problem with the ZL and mine also to have this problem...the problem maybe lies with the internal battery...you need to send to Sony service center for replacement...cause nothing in this forum can solve that issue...just if you brave enough, you could change the internal battery yourselves to test if that's the problem...

Weird Power Issue with all custom RoMs

So I took out my age old xperia M(single sim) a couple of days ago and installed cm 12.1 on it. The only issue I'm facing with it is that if I keep the phone on standby for a while the phone completely and silently shuts itself off. When this happens it doesn't turn on with the power key as well so the only way to turn it on after this happens is by removing and re inserting the battery and then pressing the power button. (phone boots normally then)
This problem only appears when the phone is in standby. I could use it 2hrs straight and the phone would keep functioning normally as long as I don't keep it on standby for a long period.
I've tried tons of different cm12.1 roms and factory reset the phone multiple times but the problem is there with every single rom. Haven't tried any rom that isn't based on 12.1 yet.
Strange thing is that this standby dead thing doesn't happen when there is a music app that's playing some song while in standby. Even if the phone is on silent and media volume is 0. So the temporary fix is to keep playing some song and keep media volume at 0. I would be really happy if someone comes up with a permanent solution though. Thanks. Any help would be greatly appreciated

Was the problem present on the stock ROM?

I have the same problem with CM based roms, went back to stock and it doesn't have this issue, could it be something to do with ambient display/doze?

No, I don't think so. Which version did you come from? I would suggest flashing 15.4.A.1.9 first because most custom ROMs use it as base and doesn't offer full compatibility with older versions.

Nope. My sister had been using this phone on 4.3 since 1yr now. I decided to use it as a secondary media device when she got a new phone. When I first unlocked my bootloader after rooting the device went into bootloop. So had to restore it to stock 4.1 Indian (couldnt find 4.3 indian ftf) using flashtool (took 2 days and tons of researching to get the drivers working). Then I rooted it again and flashed twrp and cm 12.1. Have been facing this problem ever since.
It's driving me crazy now. Might go back to stock if it doesn't get fixed
Edit - also just checked the sim slot isn't working either. Tried multiple 12.1roms but it won't get detected. Didn't realise this before as I'm using this as a media device and don't need sim card working anyway.

Do what I said to @kurtbvb too, as it may just be base incompatibility. Flash everything except the TA partition (if present) and wipe /data and /cache.

So do I flash stock 4.3 using twrp or do I need to flash the ftf file using flashtool ?

Flashtool. Some files are required which custom recoveries can't flash.

Just flashed the above mentioned ftf file and then rooted the phone, installed twrp and then cm 12.1 based rom. Everything runs perfect now. No random shut downs and Sim card works as well.
Thanks you so so much

stepcounter complete wrong

I have an SW3 but since few month the stepcounter don't work correct. Is it possible to fix it?

The answer would interest me as well!
Unfortunately my stepcounter doesn't work anymore since a few month and i can't get it to work until now

Notice same issues.
Due to GPS problems, my SW was replaced today but no stepcounter is always zero...

Stop working completly. Is it possible to reflash the Software over fastboot?

Nothing surprising that stepcounter works like crap... mine acts the same and it's getting more and more inaccurate so I stopped caring. But if it doesn't work at all then there's something wrong. You should try repairing the software using Sony's windows application.

For ne ist works again. I have no warranty anymore. I flashed an twrp Recovery and the only available Rom and Kernel. Now it count my steps.

I can confirm!
After flashing TWRP and Rom the Stepcounter works.
