So I was bored today and decided to poke around the guts of my US tab pro 8.4 and after pulling the back off low and behold but despite popular belief the battery is not soldered. It is replaceable. Currently I'm looking at the WiFi deciding if I want to try to rig something up to fix this infernal thing.

Could you explain how you took off the back cover? I'm having battery issues with mine...

Ok so I have found a source of everyone's wifi Signal problem. Samsung used a cheap ribbon wifi antenna attached to the tablet back? It is on the lower left corner if your holding it in portrait. It is the single smallest and worst connected ribon wifi strip I have ever seen. Samsung cheaped out in a huge way on this and we are paying the price. Currently I am contemplating how I want to use to fix their mess.

I'm very curious about your explorations. Keep us up updated! I'd love to fix the weak wifi signal and possibly upgrade the battery later at some point.

I'd also like to know how big a deal it was to take the back off. I looked into doing the same but felt like I was going to break it.

Well after a long day of playing around i managed to accomplish getting around the signal drop by using a peice of conductive metal tape as a carfully cut strip going down the speaker and across the battery. Works good. Till I played some more and broke my stupid wire connection. Now ima have to call samsung and see if they even sell the part which I doubt lol. Playing with the wifi antenna of a broken galaxy note 10.1 atm but it doesnt want to play nice. Still the conductive tape works well. If you dont break your tablet lol. I may do pics tomorrow

Sounds good, good luck on fixing the antenna, I'm sure there's parts for it. That's stuff is pretty universal

Here are some photos of the internals on the sm t320 I took apart
To disassemble the sm t320 I sinply used a prize tool around the screen edge. You can watch a video tutorial teardown of the note 10.1 2014. Same process

This is the tiny wifi antenna on the lower left of the tab pro 8.4 in portrait mode. I believe this is the cause of most of the signal woes on this tablet. It connects to a wifi board simply by pressure contact and it is not made of quality materials to give good range

This is 8.4 tiny wifi antenna card. After modifying this card several times in repeated attempts to get better and better signal I busted the contact of of this card. This called me no end of aggravation and it took me almost 10 hours to come up with hey new solutions so that I could get wifi signal again. I had to modify the chassis and use a note 10.1 wifi card in my galaxy Tab Pro 8.4. My signal is now as good as it ever was but no better due to the impedance of this card. I did succeed in boosting signal on the original but I got greedy. In the process of trying to figure out the part number of this board so I can order a new one. If you look closely you will see the contact for the wifi antenna that is attached to the inside of the back cover

The sm t320 battery is replaceable, not soldered like some have said.

If you can while it's apart, provide some quality detailed pics of the placements of the tabs holding the back on. And the best place to start disassembly.

Would also like to see your fix for improving the signal

Thanks for all your work, it really helps alot

They need to make a bigger battery. Battery life is good, but could be better.

I agree, I took back off yesterday and checking things out, needs higher may then what it has.

I thinking of doing a disassembly video for youtube, just not sure when I'll have the time.

Does the bezel stick on to the screen or back cover?
10.1 2014 has the bezel stick on the back cover. Tab pro 8.4 seems the bezel stick on the lcd.
Please CMIIW..

When taking back off mine (8.4) I started at the sdcard location, which made it easier.
Just remember to be careful not to plunge tool into device to far and also to not break holding clips off.

Does it look like there are pins to connect a qi inductive charging receiver? With the battery life being a concern, it would be nice to be able to use a charging mat to top off.

Not sure I didn't do much, except to remove the back. As far as the receiver goes, I guess anything is possible if you have the knowledge.
