I've had my A1-810 for about 6 months, and it has worked well for me. Never had a problem with any of my headphones.
I recently updated to KitKat (4.4.2) when I saw the notices. It seemed fine, but later when I tried headphones, it was intermittent on recognizing any of them, and now it never recognizes them. Audio continues through the speaker, and I get clicking noise in the headphone.
I've seen other complaints about this, but no real solutions. Going forward, the headphone jack is critical to me (I will be listening to podcasts and audio books in bed).
QUESTIONS:
1) This seems pretty common - are there any update plans for my tablet and KitKat? I'll contact Acer direct if no one here knows.
2) If there are no plans for KitKat fixes, I really need to go back to JellyBean (4.2.2). Can someone point me to a detailed process for this?
3) It also seems intermittent about charging. I've been plugging the charger into a Kill-a-watt meter so I can tell that the charger is drawing ~ 2~4 watts. Sometimes it just doesn't draw any power, and plugging-unplugging will get it to charge. This also seems to be related to KitKat.
I did a full reset, and these problems persist.
