Phone cut off problem! Have tried everything i can think of

[Latz]

Hi Everyone

Got a Wizard (badged as an O2 XDA MINI-S) about 4 weeks ago but having nothing but problems with the phone functionality.

The problem:
The phone will loose connection to the O2 network. I could be in the middle of a phone conversation for 3 mins or so and it will act like it has lost reception. I look at the screen - it shows the call still connected and the signal strength shows full. Then the screen will say disconnected and the signal strength will drop to nothing yet the GPRS indicator will still be there. I either have to reset the phone or switch the phone to flight mode and back out of flight mode! This problem occurs if i make calls or recieve them.

I bought the phone on the standard ROM from O2 then upgraded it to the ROM version 2.21.4.101 which gave me the push functionality AUTD. I didn't use the phone long enough to tell if this problem occured after the ROM update.

Thanks to Faria and Machinagod's postings on here i was able to CID unlock the wizard to try a different ROM to see if that cured the problem. So i put the IMATE K-JAM ROM version 2.16.9.1 on yesterday, didn't add anything else on it, still the same problem!!

Any ideas anyone? i'm pulling my hair out now!! :evil:

First i would try cleaning the sim contacts, both on the sim and device. Sometimes faulty contacts lead to this problem. (poss faulty sim - have you another sim you can try?)

Next i would contact o2 to check there is no fault at their end e.g. faulty transmitter, computer systems.

If none of these solve the problem then its prob a faulty radio on your device and i would exchange for a new one.

Do you have a SD card inserted ?

If so remove it for the day and see if the problems persist.

Thanks for the suggestions guys.

The SIM card works fine in other phones (i've not had this one for long!) so i hope thats not the problem but i'll give it a shot. I'll try getting rid of all the contacts etc on the sim and phone and see what that does.

SD card - yes i have one inserted now but the problem was still happening when i didn't have one in there.

Any other suggestions?

Thanks for your help so far :-)

heheh i think he means the actual contacts on the SIM! you know the metal bit of the SIM that makes contacts with the pins inside the phone!

not your phone book contacts! :D

HAHAHA LOL Stupid me!!! :oops:

lol thanks for pointing that out. :lol:

[Latz]

right - that didn't work :cry: anyone else have any ideas what could be causing this?

I am having the exactly same problem.

I am going to request a new SIM card from O2 as I think it is due to the SIM. Will let you know my result.

Exchange your phone - maybe a faulty radio in your phone. You could try a new sim but as you said you've tried it in other phones and they are ok.

[Latz]

Darklondon - thanks very much i'd appreciate the feedback!

Meschle - i've got to say i think i agree the phone has a problem! i just hope that if darklondon manages to resolve his issue with a sim card mine will work with the same resolve.

I also have this problem. Im on the T-Mobile network in the netherlands. When it cuts off you can see that there is no more radio contact (there is a cross on top). It then resets the radio and gets back. Within 10 seconds of the cut off i can be called and call back????

[darklondon]

it's been a month since my last reply and I havenot yet change my SIM yet :shock:
however, i think i found the problem, at least, i think so.
the constantly cut off issue, for me, it's due to the overclocking. initially i overclocked my CPU to 264, which brought the instability to kill the "phone" program constantly. if you have any task manager try to kill a "phone" program, and you will see the signal bar goes off completely.
so, i changed my overclocking to 242. problem solved, no more cut off now. :D

[Latz]

wow really?! but i'm not overclocking .... mayube i should! i don't see the phone program in task manager?

[darklondon]

I can see the "phone" program or say thread with SmallMenuPlus and vBar. And sometimes I can see more than one.

[TauTau]

hm, I don't see a "phone" process with Memaid, but I'll try the reducing of overclocking too, since I have the same problem. 240 is the nearest option to 242 though in my omapclock...

I've found that this problem occurs using many of the AKU2 ROMS out there along with an application that requests a GPRS connection on a very frequent basis (GoodLink for me, MSFP, Agile Messenger for others).

The problem is that the application requests a GPRS connection, and for some reason the device decides to drop the call in order to connect.

For myself, this started happening after upgrading from a 2.17 summiter ROM, and continues regardless of what ROM post 2.17 I use. I've also tried flashing many different Radio ROMS, all to no effect.

I've been back to 1.8, and that's solved the problem. I'm now using a 2.17 ROM that I flashed today to see if the problem persists there.

This isn't an overclocking problem - as I never overclock.

I have a AKU2 ROM installed, though I never use GPRS (way too expensive here). So that can't really be it I guess...
