O2 XDA Atom

Hello averybody, I'm new here. Please help me, my O2 XDA Atom cannot play sound. Someone please help me....
No sound problem
Hi
This normally happens when the headphone is plugged out. There is a small microswitch inside the headphone socket to detect the unplugging of the headphone.
Try inserting a pin and gently moving inside the headphone socket. This releases the switch and audio is back to external speakers. It worked for me.
Hope this helps

[Q] Is it possible to record video from a helmet cam via 3.5mm or micro usb?

Hi
I'm hoping the smart people here at XDA can help with this; tried searching to no avail.
I'm going snowboarding soon and have access to a helmet video cam. Is there an app that would let me record video from this cam to my internal or external sd card via 3.5mm jack or micro usb?
I have the 16gb internal sd and an 8gb external sd, so I'm not short of storage space. Recording to the phone sd card would be alot less bulky than using a portable dvd or similar.
Any help/advice would be much appreciated!

[Q] Broken mic - potential work-arounds?

This is an odd request, but please bear with me...
I've recently had the microphone fail on my Desire and due to the amount of playing around I've done with it, it's not really claimable under warranty. I was wondering if anyone has ideas for how to use an alternative mic, perhaps one that connects via Micro USB or even maybe one that will plug into the headphone jack. Any ideas?

[HW][XS] Speaker & Sim card holder problem

Hello, sorry for the wall of text.
Since August I' ve had a problem concerning the internal speaker, where extreme buzz would appear during music, calling and ringing, in irregular times. At first, tapping the back and/or pressing the back plate firmly would solve the problem for a short time. Frustrated, I opened the back plate and tried to raise the speaker contact legs a bit, this helped only for a day, then the buzzing reappeared. Opened the backside second time, and accidentally cut the ribbon cable for the sim holder and nfc. rendering SIm cards useless.
Afterwards, I sent the phone to a repair shop, and bought the new spare parts, which are sim card holder and internal speaker.
The thing is, the buzz is still there, as the repairman says, and now the phone, while recognises sim card, cannot connect to network...
What could have gone wrong? Can anyone elaborate on my problem? Thank you.
P.S My phone used the .96 FW with Zultra framework and lots of addons, which worked perfect before I wrecked the ribbon cable.
Update: Phone can connect to network properly now, but sound problem remains. Both the internal speaker, the earpiece and the microphone have a buzzing sound. What could it be? Please help me, since I don't have the phone for nearly 2 weeks.
Please, someone with an opinion?

[Q] ZF2 and Square Reader

Hi all,
Has anyone had success with using a Square Reader to take credit card payments on the Zenfone 2? I can't seem to get it to read the card, despite seeing the notification that the phone recognizes a "headset" is plugged in.
