Trying to identify the purpose of the two poles on the ZE551ML - ZenFone 2 Q&A, Help & Troubleshooting

Especially the one labeled U6002, which was lopped off in my attempting to remove the middle ribbon cable (during Step 9 here). All I've been able to find is generic information like this, but these numbers could be purely coincidental.

They can be glimpsed at the bottom of the second pic here:

But... it's written in the pic, these are the pogo pin for the NFC antenna which is in the back cover.

Thanks. I didn't know that, since the arrow is distinctly pointing away from what I'm talking about and to something else. Also, it uses singular "pin" and not "pins," so that also was deceiving.
Anyway, the surface of the board revealed when one snapped off appeared not to be metal, so I just super-glued it back on.
I have not tested NFC yet, but I never use it.

I am using NFC for more than 6 months now that my bank support AndroidPay (now GooglePay), you need the NFC antenna to pay with it, I pay with my phone everywhere, very useful.

I just read up on it, and it does look useful. I'll try it out.

HTC one mophie case problems

This will be my third case I will be returning to best buy. Two of mine (black) one of my wife's (silver). All of them having the same problem.
Randomly stops charging.
Won't charge.
Won't show indicator battery leds.
until I plug and then unplug the case then it's back to normal.
I emailed mophie on the issue since I couldn't find any similar issues on Google and asked them what I can do to prevent it or what I am possibly doing wrong.
They just send me an automated response telling me to file for a warranty claim.
So here I am asking if anybody else has the same issue I do and if they found a work around or any information. Right now it's just a really expensive phone case and the fact that I have to plug it in to activate it defeats the purpose of an external battery case.
Thanks for your help.

There are two other threads in this forum about the mophie case already, both of which describe this issue (I returned mine for good because of it). There doesn't seem to be a real fix for it: there are just apparently a whole lot of bad units.
I have gone through 3 cases all with the same issue. I am headed back for case number 4 later today.
My first one had this issue. Got it replaced and the one I have now works perfectly.

Yeah it's REALLY annoying. I've gone through 3 cases myself and the problem never resolved itself. The only way I can use this case is if I never put on the top, which is stupid but I deal with it because I don't want to carry an external battery. Has anyone pulled off the top plastic power button and have it still work?

That's how I fixed the first one I had before I decided to exchange it. It works fine but it becomes annoying to push the power button on and off with it recessed like that.

same issues here
I am about to return my second Mophie juice pack for the HTC One. I am having exactly the same issues; the juice pack randomly "forgets" it's charged and ceases to function, unless I plug it into a power source, at which point it "wakes up" again, but then it will stop working AGAIN before it has even used all its charge. What's ironic is that I have been a huge fan of Mophie products for the iPhone, having bought several of them for my wife's phone, and they've never had issues like this.
Mophie really needs to come clean and issue a press release explaining that the juice pack for HTC One is faulty, and they should issue return labels to EVERYONE who has bought one, as a gesture of good faith. Many other companies out there are catching up to Mophie with battery cases of their own, that are of inherently better build quality. Sorry Mophie but you stepped in it this time.

As you can see from my previous posts my Mophie case was working fine for me............until I updated to 4.3. I am now having the same issue stated by many of you. It randomly forgets it's charged until I connect it back to power and then sometimes it just completely loses all charge and needs to be recharged. Seems it isn't a hardware issue but some sort of glitch brought upon by specific OS versions.

I realize this won't help much immediately anyway.
But the Verizon HTC One just got its' 4.3 update.
It does not include Sense 5.5, it's only Sense 5.0, but to get to my point:
One of the fixes in that OTA's changleog, was a fix for the Mophie Juice Pack.
So it would appear that HTC is aware of the issue and I would assume any OTA's that come from here on will include whatever fixes they are now implementing to reduce these issues.
Just thought I'd pass along that info for whatever it's worth.
That's the update that broke my Mophie.

Oh I assumed you were on a different carrier based on your signature...my bad.
As not all updates of the same Android version are the same across variants.
This is a conforting thread to see here, being that I have just ordered mine and it is coming in monday.
If MHL dosent work with the thing on, i will probably return it. I think i saw someone confirm that it wont work on Android Central Forums- I hope they are wrong.
EDIT: confirmed... The mophie case does not work with MHL.. I guess they were to cheep to add the 4 extra pins to the damn case.. I'm sure the iPhone version has all 32 pins on it

I'm using a T-Mobile HTC One that already has Android 4.3. But that's beside the point; the issue is with the Juice pack, not the phone or its software version. The juice pack "forgets" its charge when not even in use (power button turned off), therefore it has no interplay with the phone's software, so the problem is not related to phone software version.
Oh and FYI I'm now on my FOURTH HTC One Juice pack from Mophie, and it too is faulty. I did an online chat with Mophie tech support and all they did was issue yet ANOTHER return label, and did not acknowledge any awareness of this issue occurring with other HTC One Juice pack owners. So we have the corporate mentality at work, which is to say "never admit that your product is faulty."

I've had 3 bad ones that I picked up from AT&T. I stopped at Verizon and all of theirs worked perfect. The AT&T ones had extremely short connectors, the ones at Verizon had connectors the same length as the connector on the USB cable. The difference was clearly obvious.
Possible HTC One mophie solution
Hello all,
I have read all three threads on the mophie issue for the HTC One, as I was having the same issue with my new mophie; not charging or intermittently charge, top was hard to push on, and mine even seemed to have the micro usb connector misaligned. Seems as though something was not connected correctly internally on the mophie. I decided to take apart my mophie case and found that the male micro usb connector that connected to the phone had a broken plastic support bracket which cause my intermittent issue. If you are somewhat mechanically inclined and do not care about the mophie warranty, here are the steps that I took to fix my mophie:
Tools needed: Flat tip and Philips jewelers screw drivers, double sided tape, super glue (or gorilla glue), double sides tape, and some non metallic spacer (I used tape folded over a couple times)
1) Slide the flat tip in between the 2 lays of plastic and pry them apart carefully, I started by the mophie's camera hole for the HTC one and worked my way towards the other end.
NOTE: You might here some popping and cracking, this is due to the ultrasonic bonding process used.
NOTE: When prying toward the micro usb with the flat tip be aware that the battery starts just below the camera opening.
2) Once both pieces feel separated pull firmly on the plastic that has the mophie serial number, try pulling different direction, understand that some resistance will be there due to the double sides tap between the plastic and the battery.
3) Once battery is fully exposed pull battery out slightly to release double sided tap on the back side of the battery, while simultaneously pulling micro usb toward the top or camera opening of the mophie case.
4) Locate micro usb plastic support bracket, removed 2 Phillips screws to access bracket.
NOTE: At this point is when I had to repair the plastic bracket in mind with some gorilla glue. Be mindful that unless u want more work u still have to work with the usb connected to the circuit board.
5) Reinstall phillip screws and place spacer between plastic bracket and micro usb.
6) Following steps 1-4 in reverse.
My mophie works like a champ now! And the tope even fits without having to force it! Hope this help someone else out. Please see atched pics for clarification purposes.
My first mophie works perfeclty and has no flaws. Wish I had that luck with my phone LOL.
SOLUTION
Hey guys! So, I disected my case to see if I could manually fix the problem and I figured out what the problem was. The little micro USB inside the case is getting pushed inside and so when you try to plug in your phone it never fully plugs in.
So, the easiest solution would be to take a pair of pliers and very CAREFULLY shimmying the USB plug out. Then, it should work like a charm.
Also, to prevent this from happening from the future, when you insert your HTC One into the case push down the bottom part of your phone to insure that it slides onto the plug without pushing it down again.
And just another problem I experienced with this case was the built in power button. I found it was pressing in my pocket and also when I put the top part of the case down the power button would stay pressed. I simply sanded the bottom part of the built in button down and that fixed it.
HOPE THIS HELPS!

[Q] Transplant Surgery - T999 mainboard into SCH-I535/SPH-L710 body

I have been looking around, but no place specifically answers this exact question.
Long story short I have a t-mobile Mainboard that I want to save from a phone with a broken screen that I have. From what I understand the other components work as well (camera, speaker and whatever else). I understand that I can purchase an LCD/digitizer with assembly and carefully place the components into there to make sure the phone works but it would cost me around $120 for the parts + whatever time it takes me to replace the components. My second option which I am asking to see if it is indeed possible, would be to take the mainboard from the T-999 and replace it with a SCH-I535/SPH-L710 that I would purchase (most likely with bad ESN - costing me the same amount) but it would mean that I would not have to deal with screen replacement and I have a higher likelihood of having a good quality screen. (I have never been happy with the quality of screen replacements from ebay). It makes no difference if it doesn't work, but someone with the experience of working with different models should be able to answer this question.
Why not buy T999 with bad ESN ?

I am trying but T999 with bad IMEI's are not only more expensive but a lot of them also have broken screens so im back where I started. I am just stating these two because I can find them cheaply and easy to find as well.
In that case, you could try taking the Display & Digitizer from those phones and put it in your phone. Don't try to transplant your motherboard into that phone unless you have a good reason to do so.
It functions but you have to use a case and...
I did this a about a week ago. Here's how it went.
I bought a SPH-L710 without realizing it did not have a sim card slot. The screen had one slight crack and everything else worked.
After receiving it, I bought a T999 with a cracked screen/ non-working digitizer and everything else worked (the seller heard sounds when it powered on.)
I disassembled both and put the T999 mainboard on the L710 screen digitizer. Most of the screws line up. The two screws that don't line up are:
1. at the bottom near the TOP of the USB port. The hole in the board and the hole in the digitizer are on opposite sides of the USB port. This cannot be remedied, where the screw goes through the board, there's no hole on the digitizer, and you can't put a hole through the mainboard to meet up with the one on the digitizer. You could try but I think there's a circuit on the board there, or not enough room.
The two holes on the SIDES of the USB port will line up only when you squeeze thee mainboard and digitizer together while installing the screws.
2. on the side near the power button, there is a screw that goes there, but on the T999 mainboard near where the screw goes, there's something that looks like a button cell battery about 3mm wide and 1.5-2mm tall. It stuck in a hole made for it in the T999 digitizer, but the L710 digitizer does not have a recess in it to fit this button cell so the T999 mainboard sticks up slightly, enough that if you put the screw in the hole in the side, then the power switch on the mainboard will not stick down far enough, and when you push the power button on the outside of the case, it won't engage the power switch on the mainboard. To remedy this, leave out the screw on the side of the mainboard.
Because the mainboard is slightly bent due to the button cell battery, you need to have a case that compresses the phone together so the power button will engage the power switch properly. I used a "waterproof" chinese knockoff case I got on e$ay for $13. It's not waterproof, but the phone didn't get ruined even thought I tested the waterproof-ness of the case before I put the phone in and it passed, so maybe a genuine otterbox case would have been better. But the case does OK to compress everything enough that the power button and power switch work all the time. With the case on, you can't tell the phone is missing screws internally.
Verdict: everything works properly except the camera doesn't focus properly, it only works in Macro focus, I don't know if I should take the camera module from the L710 and try it or if it won't move because of the stress of the mainboard being slightly bent all time due to the button cell battery. It did focus properly for the few few days I had it.
One other issue: I can't get Windows 7 to recognize it, so I can't use Odin to root it, I've tried all the drivers, I've tried all the modes. I have no idea if this is a Windows issue or if it is somehow caused by the Frankenstein's Monster-ness of the hardware.
So yes, it can be done, with a "rugged" style case and with a few issues. I have no experience with the I535 at all.
I hope this helps,
rollinns
I could not have asked for a better reply. Thanks so much!!!!
Glad I could help
I was looking for this info about 3 weeks ago and didn't really look that hard since i was pretty sure everyone would give me the same replies you got before I replied. But for my entire life I've been asking questions no one else has asked, so I'm used to just having to do stuff to get answers. In this case, it helped you too.
If I had to do it over again, I think I'd try the whole process w/o the L710 parts. Maybe the I535 will work, and I still could drill a recess into the L710 digitizer if I had a mill, but I don't have access to mine now and won't for a while, and I'm not sure I trust the drill press to not crack the digitizer.
Also - NFC is less reliable than it was with my S2, meaning it doesn't work all the time - it's harder to beam contact info to another phone, but QI wireless charging works flawlessly.
My hope is to put some NFC tags in the truck along with a wireless charger so I can listen to internet radio as I drive, i.e. - a tag to turn off wifi, turn on bluetooth, turn on the app that streams music to my JVC car stereo and turn on the "TuneIn" app. and then I can still charge my phone without worrying about wires.

[FIX] GPS issues, antenna cases only E98X, requires disassembly.

I thought this was worth sharing, this is my second thread ever on XDA and hope it helps somebody.
Quick story about my case:
I tried software fixes, ROMs, and made a lot of reading, when I finally figured it could be an antenna issue, I decided to give myself a try on my cellphone repair skills, turns out I turned a “nearly dead” GPS taking 10 minutes to lock into a “better than average” GPS taking 20 seconds to lock. Time taken for the task, 15 minutes, time suffering from bad GPS signal, 1 year, go figure.
Let’s see if you are a candidate to try this solution:
- You must be sure this isn’t a software related issue (i.e. my GPS works with X rom but it doesn’t with Y rom, that would certainly be a software issue).
- You CAN get a GPS lock but the signal is weak (i.e. constantly dropping signal in an area where you are sure another phone works fine) or GPS locks takes up to 5 minutes (and you already tried a software fix to speed up GPS lock).
- You’re phone is relatively old (i.e. it was bought when it came out, although I’m sure the quantity is low, I assume there are still E98X phones which are brand new and I would not recommend disassembling a brand new phone).
- You have experience opening cellphones (i.e. experience using small phillips screwdriver, gently popping frames/housing/covers, putting back in position plastic buttons before re-assebly).
Before we start, quick explanation on what may be happening to your phone if you are a candidate:
- Presumably, the GPS antenna (and Bluetooth, 3G/4G as well) is making poor contact with the springs on your phone.
- This phone uses contact springs for pretty much everything (see attached picture for springs locations of antennas), so these springs and/or the antenna contacts eventually bent away from each other and lower your GPS, Bluetooth, 3G/4G signals.
Here is what you need to do:
- Remove the back cover, and remove the back frame (See the following video from minute 0:00 to 1:50 for disassembly of backframe https://www.youtube.com/watch?v=S9OJRtf39QA).
- Inspect every spring and antenna contacts (see attached pictures for antenna springs and pad locations), make sure they are not rusted or damaged, else you need a replacement part for it (for antenna pads, you may want to clean those with isopropyl alcohol if you have some).
- Using a soft, thin, *plastic* tool (thinner than a credit card, but sturdier than paper), lift every spring you see up to 10 degrees (see attached picture for reference) and wiggle it up and down to force it to stay tilted up about 10 degrees (don’t force it up more than 15 degrees when wiggling or you risk to break the spring, there are quite a few of springs, I remember at least 5 pairs, so make sure you get them all done).
- Revert all disassembly made (See the following video from minute 6:32 to 7:51 for reassembly https://www.youtube.com/watch?v=9QxLa5rXX7Y), and VOILA!! your GPS signal came to life again (and hopefully your Bluetooth and 3G/4G are enjoying the new perks too!)
-Additionally, better 3G/4G signal does save battery, your cellphone amplifiers require less work and produces less heating too.

I was looking for something like this. Thanks very much..........
Let me know if you need anything else (i.e. more detailed instructions) and report back your results, unfortunately for the audience, I didn't take pictures of the process since I wasn't sure it was going to work (and then just took the picture of the NFC springs), so if you can take some pictures of how the contacts looks in the inside, that would awesome, I can update the main post with these, there is quite a few springs inside so you want to make sure you get them all in shape.
I forgot to say in the main post, better 3G/4G signals give a lot less of work to the amplifiers, which means less phone heating and less battery consumption, this is a nice service to do to a 2 year old phone like mine.
Enclosed is a picture from a replacement mid frame cover. Could you please use something like ms paint to circle which pins you bent upward? Looking at my Optimus G Pro 980 Mid frame cover and motherboard/logicboard I do not see these........

UPDATE:
See main post, I got a picture from somewhere else for the spring locations.
Actually my friend, that picture only shows the pads for the antennas, try to match it with your phone and see where they contact, these are going to be the springs, they don't look like spiral springs, these are other type of springs which I don't recall the name but they are more like a V shape, and one of the sides is attached to the board and the other one "springs" up and down, let me know if you got it or I will open my phone again, just for you! (no kidding)
Also, if I were you I would try to do the same for all pairs of springs I see on the motherboard, there is a pair for the speakerphone and one more down the board for something else.
GPS finally fixing
Thank you so much for this post. Before this solution, I tried different roms, gps fixing apps, disabling carrierIQ, editing the gps.conf file to add "better" servers, etc. This is the only solution that really worked. Now I am getting a GPS fix in 10 to 15 seconds where before it was up to a minute or more. I have an LG E980 (ATT Version).
As directed, I turned off the phone, removed the rear case back, removed the battery+sd card+sim card, removed the screws in the back panel of the phone and then separated the back panel from the front panel to expose the circuit boards and spring contacts. Then, I cleaned all the spring contacts and their mating flat contacts on the back panel with alcohol. Then I bent all of the spring contacts up slightly, re-seated the back panel making sure the side buttons were in the correct place (I do not believe the quickmemo and power buttons are interchangeable even though they are the same size fyi), and then secured the screws back in place.
Thank you!
Way to go buddy, I'm glad I could help you and that you were able to follow those horrendous instructions, I can't be sure on your case since yours wasn't as bad as mine, but on my case it also improved 4G reception overall, these antennas are used for pretty much everything so it would only be logical to get better signal on all the services, this is a "must" service on old E98X phones, perhaps nearly half of the GPS and bluetooth issues on the forum are due to this plus a weak or faulty software filtering not helping.
any info how to increase the wifi antenna? could this be the white cable?
Sent from my LG-E980 using XDA Free mobile app
I've quit using my OG Pro because the GPS is so poor. Hard to get a fix and drops constantly. Glad I stumbled on this, and will give it a try.
Can you point out which springs are specific to the GPS antenna? I suppose I can try to work with all the springs, but with my luck, I 'll break something that was working fine.

I don't know which ones they are. I did all of them. They are a lever type spring contact so it is hard to break them. Just do so lightly.
Wow fairly simple fix with great results, thanks!

Just tightening all the screws fixed all my GPS issues. No disassembly required! Add this into OP.
Thanks
Just did this, really improved the speed and reliability of everything- gps, wifi, etc. Thanks.
A quick tip for those doing this the first time. be careful of the buttons. I've taken apart my optimus g pro a few times now, and those dern things like to fly out of you're not careful when taking it apart. Also, when putting back together, use a small piece of scotch tape on the exterior of the frame to hold the buttons in place when you put the frame back in place. make sure the tabs of the tape stay on the outside, and pul them gently as you snap the screen back on. It's easier to have the frame on the table on put the screen down onto the frame when done this way, and save those dern buttons from coming out of their slots.
I have two OG Pro (E980) developed same broken GPS issue.
Now, I think the problem is the two soft contact pads, when I bent little bit, the GPS 's issue got fixed.
Also, the method not to improve any 4g/Wi-Fi/Bluetooth.
LG made such low quality contact PINs
Two years have passed and this thread is still helping people with their now "ancient" G Pros. My problem was that the coax cable had popped loose. Still I went ahead and re-tensioned all the contact springs. GPS is now functioning like new. Thanks to all who contributed.

it is possible to adapt him one wireles receiver ???

My question is based on that, the back of our Moto Z Play will be adapted certain mod, s including this extra battery and a version of this, it has been adapted to turn wireless charging, so he proposed me that together we get on very, very little money.
With that premise, the first thing we have to be aware that every touch point is that back.
I have numbered the contacts so that each is its function without possible error, I have not yet started to take electrical measurements of each and every one of them even the bar for me has all the earmarks of being earth ( -).
I guess somewhere you could see that information even officially and keeping that already fixed, the rest would take a wireless receiver of those in Ebay or Amazon, etc etc tec. and with them even performance testing and that, considering the original back cover cover the whole shebang given thickness having the receiving plates is about 1 millimeter or 1 with a tenth desmereciera I do not think the whole.
That is, to work and I hope that with this idea, collaborate to launch even more this thread.

Zenfone 3 Deluixe 5.7 owners - please confirm?

Conflicting reports in regards to NFC on the higher-end Deluxe models. GSM Arena reports it's available, PDAdb, which i believe is more reliable doesn't even mention 'NFC'.
I believe this VERY common feature has been 'avoided' in this phone, absolutely foolish by ASUS as it's keeping me away from this phone. Can someone please confirm? Anyone know why this decision was made despite the fact they have the 5.5", 5.7" deluxe variants and the ULTRA, which isn't much better?
Thanks

It is available BUT it is in the very top of the phone.
Most phones use the battery and have NFC centered around the middle of the back. The ASUS Zenfone 3 deluxe, and the ZTE Axon 7, have it at the top of the phone, around where the speaker is located.
I don't know WHY it was put there but I eventually found it with a bit of hair pulling...
Somethings need to be the top part of the back but you can also use the very top of the phone too. A little annoying as this isn't very well explained...
NFC sensor is on the front near the top of the screen.
Yes, it have NFC, in te top of the phone near the call's speaker
I used it all days with some nfc tags.
An awkward location to put the NFC. You cannot see the screen when it is contacting the other device.

Hey, so I sometimes get the NFC to work (unlike my zenfone 2) bit when I tap to send / beam a picture it goes to Google play and tries to install the gallery app. Anyone know how to send the picture instead?

I get NCF to work.. Did not realize the chip was in a different location than model 2. Model 2 is rooted and can send pics via beam with no problem. Version 3 when I try to beam tries to install the app. Don't need wise ass comments. Joined XDA for "real" advice. If I need bull**** comments, remarks, etc I would have just posted on ****ty websites. Real question for real answers. If you have nothing else to do shut the **** up

			
				
The NFC is located at the top of the phone. You could "image" it's using the 3.5mm jack as the center of antenna. (Although it's actually there..)
I use the NFC function almost daily for payment (for convenience store purchase as well as subway ride) and it works 100% of time. (never second time touch) The way I use it is screen facing me, only the very top of phone (basically where the 3.5mm jack is located) is touching the payment terminal reception pad.
Most of the payment terminal will even accept the phone lying flat, LCD up as long as the 3.5mm jack is located near center of the payment terminal's reception pad.
The reason why NFC is located at top of phone is that the back of this phone is made by one piece of metal. NFC signal will have trouble pass this metal barrier. Beside, I found it's easier to use as NFC is at top since can hold the phone 45 degrees (LCD facing me) instead stick the back of the phone flat to the payment terminal when making payment.
Also, the screen is not needed to be on when making payment (YMMV, may depend on APP). The sensitivity of NFC is even better then my cashless credit card. (I tested both at same terminal).

Thanks for the info. One of the downsides of the body design I guess... Good to see its working for you and there's a way around it. I would've gone for this phone had root been available on it by now. Lack of IR is something I don't use all the time, but still find it important and am using on my V20...
