i see that you did not update this thread as what you promise to do 6 months ago. What happens?

Hi,

I've allready posted to similar problem few months ago, so i'll paste my solution that worked for me:

I had the same problem and i am pretty sure that it's hardware problem.

try this:

1. remove back cover

2. remove battery

3. place some paper (little piece) between the phone and battery in the bottom part of phone

Paper should be placed on thin edge opposite to sim card slot. In this way you will push battery up.

After I did this my phone never restarted for 3 months (only when i manually restart it)

Hi,

my problem was a little bit stupid.

While connected Arc to PC I accidentally made a copy of one file inside ".android_secure" directory (SD card)

after that the phone started restarting. It was confusing since even with the SD card out the phone restarted.

Deleting the "XYZ - Copy.asec" file (on another Xperia through PC) made my Arc restart again and then work OK.

Looks like this Folder is used by some installed apps (& games) for their startup and if there's some corruption, s**t happens.

I hope this helps some 1% of you.

So what is the status now? Did you try the repair or tightened the battery with a paper? Bcos I'm facing the same prob here.

My arc s is only 2 weeks old and I'm facing the same problem. I didn't update it to ICS and installed some games from gameloft and some applications from google play.

Following are the list as I can remember.

1)Tuner - gStrings Free

2)GT Racing: Motor Academy Free+

3)Brothers In Arms® 2 Free+

4)Real Football 2012

5)Men In Black 3

6)PocketCloud Remote RDP / VNC

7)ConnectBot

😎Talking Tom Cat Free

9)Talking Tom Cat 2 Free

10)Talking Cat

11)Talking Ben the Dog Free

12)Talking Tom & Ben News Free

13)Talking Pierre the Parrot Free

14)3D Need For Speed

But I tried factory installed game which is Let's Golf! 3 and when it's loading phone leads to kind of a stuck situation. So I switched off the phone and switched on. So I don't know sometimes this might be the cause. But also I doubt some of the apps and games installed by myself could leads to this behaviour.

**But I noticed something when I'm getting more voice calls restarting happens. Sometimes during a call or after a call. When I'm not getting much calls it's not restarting I guess, not 100% sure though. (my previous phone was a xperia ray and it was given same behaviour)

I tried followings but still no luck.

1)Format the SD card first, remove the SD card and sim. Finally reset to factory default settings(didn't install any app or game after reset)

2)Place a piece of paper to tightned the battery (lot of users have the battery loosing problem but in my case battery is tight enough but still I tried)

3)I tried to repair using PC companion and SUS but both are leads to update to the ICS. So I didn't do the update after refered this - http://talk.sonymobile.com/thread/35431

4)Finally I went to claim the warranty. Now waiting for an update from them. I'll let you know once I get it back

Also I didn't try following options.

1)Switch off the wi-fi (Some users metioned they have problem with wifi but in my case even I'm not using wifi it still restarting)

2)Change operation mode to GSM only from HSDPA/GSM mode

3)Remove only SD card and try

4)Remove only SIM card and try

5)Update to ICS (The best option would be to hand it over to a sony repair center otherwise you can't go back to GB officially. If you flashed that could leads to warranty issues. Also after ICS update you can't corner the problem wether it is a OS problem or a HW problem)

Hi Guys I found the problem and restart issue solved in my Arc S.

In my case I changed the "Network Mode" in "Mobile Network Settings" to "GSM only" and since then my phone is working wihout any problem. Not a single restart even when I'm playing heavy games like Asphalt 6: Adrenaline and NFS Shift.

As I said earlier in my previous comment I tried all the options I metioned and had no luck. So I claimed the warranty and got a new phone as well. After one or two days it also restarted. So then as the final step I upgraded OS to ICS. But restarting problem is also there with the ICS. So I gave up and as the final try I changed the "Network Mode" in "Mobile Network Settings" to "GSM only". So it worked for me and greatly running with ICS. It looks like there is a HW problem in SE receiver I guess. Sometimes this solution might not working with your handset because it may be related to your country as well I think. BTW I'm from Sri Lanka.

So give it a try guys...
