I love my TF700!!!! I have had no issues i didn't have with galaxy tab 2 7.0. Asus has been among the best PC motherboards, I love them. I liked the tab2 7.0 jusr fine, but wanted HDMI and a 1080 screen. Had a friend complaining Android tablets are slow and not smooth, but after an hour with the asus they were ready to give up on apple. It can get slow or unsmooth if tons of apps or webpages are in use or it hasn't had a reboot in a long time. It came with 4.1 and got the 4.2, no huge difference i recall. I can�t wait for 4.3, TRIM sounds like a good thing. GPS is not great compared to my galaxy s3 or motorola bionic, but works fine if not in a building i find, not what i got the tablet for, but works in my car.
The nexus 7 is said to be wonderful, but since google has made not using sd expansion and only giving paltry internal storage part of their religion I will never, ever own one.
Sorry your having trouble with yours, can't help without more specific info. Ive never tried asus support, but find vendor support useless in general, especially compared to the great community support of most android devices.
Good luck!
I don't want to highjact this tread but I am considering buying this tablet and I have a question or two about this situation. Does anyone know or think if Asus will fix this issue in a future update? Or is this a something that won't be corrected until some sort of future Jellybean update?
For someone who is not comfortable doing the CROMI Rom adjustment is there an alternative that won't affect the warranty or cause issues for someone who is not familiar with tablets? This sounds like a great tablet except for this one issue. I would be surprised if Asus doesn't know about it.
Not sure what >this< issue is.

I really don�t think most infinities are "broken" and need a fix from Asus. This could be how its used, what apps are in use, that it was dropped, or a random lemon.
I just "fixed" a friends phone she was ready to return for a new one by changing her keyboard settings and rebooting it.
Yes Asus does make nexus 7 and nexus 7 (2013) and i had them both and the original worked fine but like many others i got the so called lag trim problem (supposed to be 4.2 problem but again other manufacturers have used that OS version without problems ); more than likely Asus used cheap flash memory.
and thinking Asus had a whole year to get it right i got the (2013) nexus 7 and again CRAPPY hardware
(1) GPS is very sporadic or just not there.
(2) ghost or phantom taps all over(had to shut off keyboard swipe as it made it worse)
(3)battery with same use works all day or other days just sucks dry so quick
( 4) WiFi some time just quits(on excellent home WiFi modem from cable
Some problems could be 4.3 problems but after many reboots i have given up on ever owning a Google Asus product [NEVER AGAIN]:'(
I will never buy an Apple product also for many reasons
I am going back to Staples to trade it in for a Samsung tablet for at least ( even if it has lower specs) most Samsung products have fairly decent quality control
I love the samsungs I've had lately, but was just with my mom and aunt and their samsung tv only a few years old froze twice, only an unplug helped. Yes, some brands are clearly better than others, but brand alone is not a great way to pic or reject a product these days. Though i'll be hard pressed to ever by an LG after the disaster my G2x was, but my galaxy s sucked too and i love my s3 so much!
