Google Wallet, NFC, and swapping batteries

I installed Google Wallet about a week ago and I must say it works very good. Aside from only being able to use it at McDonald's, Circle K, and Whole Foods so far BUT I got an extra standard battery with charger and confirmed yesterday that if you swap batteries you will have problems using your NFC to pay for things. I am not sure yet about beam operation after swapping batteries but this not being able to use Google Wallet ( and possibly isis ) is interesting. Does anyone know more about getting the other NFC registered or is this just how it's going to be?

I am considering returning my extra standard battery due to this issue and just getting the extended battery which from what I have read so far will require a Factory data reset to register that NFC. I'd rather only do one reset and get the extra juice then have to worry about if I have the correct battery installed to pay for things. Thoughts?

Where did you get Google Wallet?

You can find the link in this thread. Use at your own risk. It works fine for me, though.

I found clearing the cache in recovery worked for me after swapping the battery ( I understand it is just a work around and it should be fixed for us swappers)

Does doing that cause you to lose any other information? Cause like i said,I will probably just get the extended battery and stop swapping but i dont wanna do a factory reset. Those that asked, finding / trusting a Google Wallet source you're on your own.. Try the link above.

I see that VZW, AT&T and T-Mobile have teamed up to produce a similiar application called "ISIS" . Some press releases say it will be testing in TX and UT in February. Maybe i'll wait and see what they come up with.

No data loss just a cache clean up. Not a data reset

Perfect, Thank you

I'm swapping battery a lot and I've not noticed the same problem. Just went an buy groceries at Wholefood yesterday. The cashier was amazed to see my phone and asked toons of questions about it :smileyhappy:

Tidbits

Changing out the battery CAN cause problems. It's recommended to factory reset your device PRIOR to swapping batteries to protect your secure element. If that is corrupted the only fix is a new device.

Is that only for changing batteries, or is this for battery pulls (using the same battery) too?

Tidbits

Changing the batteries. There seems to be a problem especially with wallet installed to corrupt the secure element. There's already reports about it on XDA.

Did a master reset after getting the extended battery and Google Wallet is working properly again. Plus after what Tidbits said about corrupt secure elements I figured just reset it and forget it. One word on the extended battery Amazing! I wont be swapping anymore. As you can see on the graph I gave it about a 20 min charge but compared to all my previous 4g phones this is just awesome and the extended battery isn't even noticeable unlike those for the T-bolt and Charge.

That's some good times :smileyhappy:

I average around that time when I do not go mad crazy with netflix lol

it's not due to the extended battery, it's because of the extended battery COVER...evidently the original backplate/cover is what holds the NFC antenna

Motleycat, the NFC in the Galaxy Nexus is in the battery NOT the cover. The Nexus S NFC is in the back cover. That is why swapping bats on the GNex causes issues.

Ya...after looking further, you are right...i just saw that info & thought that must be it. GW wasn't working for me with my extended battery & when I switched back to the original battery & cover it worked. Looks like I have to start shopping Ebay for extended NFC batteries now...

GreenRobot

Nope still on VZW for sale and they're %50 off if you sign in.

Crazy. I have gone between two batteries every day since launch. Usually an extended and a regular, Sometimes if I want more juice, a third if I am going out, even though the second isn't close to dead. Knock on wood, Wallet has always worked.

Got me scared .
