     I dont know if this would help others who may have the same problem as I did with my P1 but what i did was to just take out my sim card and put it back and turned on my phone and viola no more message application watcher ...etc.  Hope this will help.  I didnt take the advise of doing a master reset.

    I have a SE p990i and have exactly the same problem also. I hanged to new sim card, updated to new ATT network, and now the problem is worse. Error message is now almost continuous, plus the phone has started turning itself off :-((

    Hey guys Im in Germany, also have a Sony P1i fon and have the exact
    same problem with the WatcherMainThread, I also cant send any sms, they
    are all pending on the sent folder. When I turn my fon off suddenly I
    get 15 sms from the last days or weeks. How come noone knows anything
    about it? Is it a virus, a trojan horse for mobiles??????? Who is
    watching and what, sms only maybe fon calls as well?? I will check here again if ever someone knows something useful.

    I also hv the same problem..went back to sonyericsson service centre here and they have no idea as well....This problem really makes me want to change my phone to other brands. Damn it!

  • rahulbhusari Feb 20, 2009

    Same problem. Precisely same thing is happening. It happened a fort night ago. I kept pressing "continue" and after 4 days the problem solved!!!
    Now it has recurred. 
    Another observation, when I switch on the phone, pending message pour in (when this message occurs...reason Application Main Thread etc..., the messages stop coming). 
    There is no other problem...

    Holla, I had a same problem, it appear when I restart My P1i. It blocks all the incoming message but after restart all pending message received. Did anyone try to format the phone? Is it works?

  • Anonymous Apr 15, 2009

Friends, this I got from allaboutsymbian website. And I already try the Test1 and it works!!!
Hope this could be much of help......

I had the exact same problem and have solved it by updating the firmware and reloading my settings from at saved bile, but it is rather time consuming.

The solution by deleting all the messages in the inbox worked perfectly fine Application Watcher Main Thread? - smile.gif
Though nothing haapend when i only deleted the outbox and sent.

I assume that the problem is caused by the message server (the small program handleing you enter to send and read messages)

I descuvered that when my phone was put into offline mode, and re-entering to normal mode , I could not open the message server.
After deleting all messages this problem has been resolved aswell.

Maybe the message server is having problem handleing to many messages.
The amount of space left on my phone was not a problem eather, arround 30 M and the insert card was empty.
but i had over 1300 messages in my inb ox when the problem started occuring.

If any ojne else is experiencing this problem, pleace keep on debugging and tributed with more result.
This will make it easyer to conclude on the results and finally determine why it is happening, based on when.

Test1 : (Is the issue resolved only when inbox being emptyed)
Here is what you do :
1. Delete all you messages - 1 in your inbox,
2. Restart the phone,
3. Send an sms to yourself.
4. Write a reply on this threat weather youi got the message or not.

if it is not resolved. please continue with 2. test

Test2 : (Is this allways resolved by emptying the indbox)
1. Delete ALL you messages in the inbox
2. Restart the phone,
3. Send an sms to yourself.
4. Write a reply on this threat weather youi got the message or not.

If the problem is stille not resolved then you have to reset the phone.

Test 3.
First of all, you must save all you phone settings, phonebook sms(despite you just deleted them all, save it anyways!) phone settings. etc.
and then reset it.

1. Save all files
2 Reset you phone by typing in *#7370#.
3. Restart the phone,
4. Send an sms to yourself.
5. Write a reply on this threat weather youi got the message or not.

If this works, then restore one of the save configurations at a time and test weather it still works.

    Test 1 worked perfectly for me. I have P990i and apparently they have the same bug. Actually what i did, I deleted most of your msgs and the important ones i was able to move them to another folder. as soon as inbox was empty, new sms started to be received! Therefore important sms can be moved to another folder. the fix is to empty the inbox.
    thanks for your support.

How to speed up your mobile.?

mostly your nokia s60 n all symbian above slow down with usage and people feel helpless.but let me tell you the reason behind it.. when you start any application or something else.... your mobile's ram(internal memory) gets used to open it.... but when you close it its thread remains open in bckckground. so to avoid it use netquin mobile guard or something else.... if memorycard is inserted you can also go to the option for removing memory card.... it will close all applications currently running in your phone... this way you can increase your phones speed

Inital text of a thread

Firstly I have to say WOW, your fingers must be tired, it is a good job this phone has a keyboard.
If you go to Android Market on your phone and search for and download an application named "ChompSMS".
This is an SMS application which can be used alongside or instead of the defaut SMS application on the phone.
Once it is installed, open it up and you will see that it shows all your message threads in a slightly different interface (looks a lot like iPhones sms UI)
You will have to scroll to the top of your massive SMS thread once but when you delete a message it will stay in the same position rather than go back to the latest message. This should make deleting a lot of the earlier messages in the thread easier.
Once you are done you can remove the application. This will not effect the messages in any way since the application is just a front end for the SMS' on your telephone.

My nokia n81 automaticly quit applycations and menu...

click and hold menu button, you should see all the applications that are currently running, select them one by one and close all of them keeping the "phone" application only.

then click once to open the menu.

you can also turn off the phone then on again. but make sure to fully EXIT the application after you finish using it. this will keep your batter life longer and save phone memory on your phone, it will also preform much faster.

let me know if this helped :)

My w550i camera application hangs


Try taking out the battery and leaving it out overnight then put back in and try to turn on again. If this doesn't help, then your phone's software needs to be flashed.
