I have 2 problems with my Xperia s ?? need help

[#1]

let me start by saying >>>> I love this PHONE

I bought my new sony xperia s about a weak ago >>> I live in Libya and there is no Sony official place to go to here ...

I found these two main peoblems if any one can help me how to fix them on my own if it's possible

1: my phone wakes up on it's own every couble of minutes and then sleeps again ...

2: the SIM signal drops alot >>> too much >>> and by the way I tried the same SIM card on my SE Vivaz it works properly and without a problem

so is there a sitteng or something that I missed to change ??? plz help

Try to reset your Xperia S and configure it again, or you can change your SIM card, sometimes it could work well in some phones and another's don't. Check it and tell me if you fix it.

Someone reported 1st issue as well >> http://talk.sonymobile.com/thread/37370?tstart=0

like RelesSony suggested, reset to factory settings and see if that fix the issue.

Good day guys, im so frustrated today......my experia S just went blank on me after nothing at all. I updated my facebook status and went to take a shower. when i came back, it flashed a blue light and when i attempted to switch it on and retrieve the notification, it didn't power on. tried the charger, and connecting through PC companion and there's still nothing happening. Can anyone, PLEASE help me!

can you remember how much battery have you got left the last time you saw it?

if the "blue' light refer to led, it usually does that when it tried to boot in flash mode. although that only happen when u press the vloume-up hey when u start the phone. wait. maybe your volume button is stuck.

Thanx for showing your concern Zann, but I had at least 70% of battery in it. The volume up or down button ain't stuck either, wonder what the problem could possibly be now

OMG Zann....how do I thank you? My babe is back on. Simple, tried switching it on while pressing the volume up button at the same and guess what, waaaalah.....she switches back on. Thank u so much Zann, I was almost panicking. You should see the smile on my face right now. Thank you so much

there's 2 way to deal with this situation.

1) Send the phone back for service. This may take days or weeks.

2) Since you have 70% battery left, you can try to re-flash the firmware ur self if you're up to it.

You can decide after reading a few posts in XDA. You can start here > http://forum.xda-developers.com/showthread.php?t=1526866

It might sound complicated, but trust me, its not. If you decide to go this path, try to see if you can connect the phone in flashmode first by pressing the volume+up and connecting your usb cable to the pc while the phone is off.

Good for you. But could you try to shut-down and restart the phone again? Just to make sure there's nothing wrong.

thank u guys >>> I reseted my phone to it's original form now the screan doesn't wake up on it's own >>>>

and for the service >>> I found these 3 options in mobile networks :

network mode : WCDMA only

GSM only

WCDMA ( preffered ) / GSM

I have no idea what these options mean but once I changed from the 3rd option to the 2nd one the sim signal became perfect !!!!

can any one tell what I did ????
