Gut shots from my PTAB7XC

[root]

I opened my tablet and snapped two pictures. Surprised to find this thing to be pretty clean inside and nicely put together. The antenna is actually a metal one rather than a flex film type. Might explain why it gets excellent reception for me. My screen has a minor ripple effect, but the insides didn't appear to be pressed together too tightly. The speaker is actually mounted on the board side, so the back cover comes off completely. Processor is an AllWinner A13. The battery is 9.25Wh/3.7V, so I calculated the capacity to be 2500mAh. I didn't see hot glue or excessive tape used anywhere. I removed the two small philips screws held the end together, then from that end, used a guitar pick to wedge between the frame and loosened the rear cover.

i think it is the same motherboard in the pmid702c

looks like the same innards in the pmid702c that i had for a bit

Thanks for doing this! I know myself as well as others have wondered about the chip and other items. Thanks for detailed pictures (clear resolution) and good to know it looks like a decent construction process.

Related question...I know some things I am looking at and others not so much, but does anyone see why the G-sensor would not work as well (aka Temple Run, etc.) for this model? Would this be a hardware issue or something that could be fixed with an update in the future? Just curious and wanted to throw that out there for the collective wisdom of the Forum.

I agree. The model # MT7000 Rev 1 and date is identical between the pmid702c and ptab7xc. These are probably identical tablets but packaged or marked differently based on the retailer that sells them.

I'm wondering about the G-sensor as well. That's about the only thing that's holding me back on keeping this thing. Everything else is acceptable, especially the battery life and wifi connection stability to my N router.

I think the problem might be that the newer Polaroid tablets may only have a 2-axis accelerometer (I don't know what they have) and some games like Temple Run may require 3-axis. No firmware updates will fix that.

Where's the microphone?

Hi all,

I was using the tablet to talk to someone using talka tone and I was wondering where the microphone is.
The microphone seems very sensitive as any touching of the tablet during conversation shows up as noise to the person receiving the call.

I do not see a hole that shows where the microphone is. Someone in another post mentioned that the microphone is omnidirectional so it picks up everything.

Any ideas about the location of the microphone from anyone.

no more PTAB7XC

I had to return this tablet back to the store, luckily, they refunded my original purchase price. After not even 6 months of light use, the usb connector broke loose inside and no longer charged the tablet. My 4 yo son enjoyed playing apps on this thing regularily. Sad to see it go.

I inspected the mini usb connector and realized that there wasn't a good method to repair the fault. Only one side of the mini usb connector was originally soldered to the system board, close to the edge of the board and without any support on the back of the connector. It was designed to fail from the start. The actual mini usb pins were still attached to the board. While I could have epoxied the connector back, I felt that this was the achilles heal to a rather well built device.
