[Q] Nexus 7 2013 LTE me571KL_SB problem - Nexus 7 (2013) Q&A

Hi. My english is bad, but i will try ask the question. Nexus 7 2013 LTE, i broked one of two double touch connectors on ME571KL_SB board, in result i have two touch dead zones(screen in attachment). I bought the new board, all seems to be ok, tablet is loaded OS, but... touchscreen is no response. I noticed that the serial numbers on the old and new boards do not match, maybe that's the problem. Question: Whether i can do something, flash or update software to work properly with the new touchscreen board?

[Q] Going to buy this phone, but I got few questions...

Is there a old model and new model, but still with the name HTC ONE X ?
I mean that probably the first phones were with few hardware problem / mistakes, and HTC probably changed / fixed these issues ...
Am I right? and if so, how to know which one is the newer with a closed box in the shop ?
I need to know anything else before?
BTW i'm buying the global version
Thanx a lot in advance for any answer
There is only one model of the international hox. BTW there are many s/n batches, you should try to find the latest s/n avaible in store. Mine is a HT23XW....... HT is the manufacturing location, 2 for year 2012, 3 is the month. So latest s/n should be free of many issues like wifi, gps (was related to bad antenna connection), sim card connection (again bad contacts Inside the phone) and yellow spotted screen (bad batches of screen for some manufacturing location). Here are the thread about understanding s/n: http://forum.xda-developers.com/showpost.php?p=24898388&postcount=13
Here are the known issues with early hox batches: http://forum.xda-developers.com/showthread.php?p=24516940#post24516940
How to test your device in store for defect: http://forum.xda-developers.com/showthread.php?t=1649943&highlight=yellow+spot
Many software related issues were solved with OTA uprades.
BTW you may wants to look at the new HTC One X+ wich haves a bigger battery, slightly faster cpu, 64gb storage and Android Jelly Bean out of the box.
If I helped, plz click thank button!
Thanks a lot

Thanks XDA Community!
Yeah, when is the 2013 LTE going to be up to date? The point of a nexus device is to always be current but yet us deb owners have been crapped on for more than a month in regards to 4.4.4. Its really gonna suck when Android L comes and us deb owners are the only nexus devices not current for a while.
Can you say something about erratic touch screen issues with Nexus 7 2013? And why ASUS / Google has never acknowledged or officially commented about it?
I'm not sure if i have to explain the issue as it's well known, but basically the touch screen has serious issues if it's laying on desk / bed (is not being held / not connected with usb or headphones)
I can guarantee it's affecting ALL Nexus 7 2013 devices, some people just dont know how to reproduce it.
It's shown on this videos for example:
Before you say it's isolated issue, here is amount of results searching for "Nexus 7 2013 touchscreen issue" on Youtube: https://www.youtube.com/results?search_query=neus+7+2013+touchscreen+issue (over 122.000 results for the lazy)
Here are some potential fixes but they are not working well AFAIK:

I had my Nexus 7 RMA'd (motherboard was replaced), and it changed nothing. Still the same issue. (i can send you RMA number if you want)
It seems to be grounding problem. (when tablet is being held or connected with headphones / USB there is no problem - as it's grounded properly)
Care to comment? Is this a bad design (Google) or production issue (ASUS) ?

Hello pre4speed,
I am just as anxious as you to see the 4.4.4 update released for the LTE model. At this time I cannot give a release date for this because Google has not released an image for this device. When it comes to the Nexus line Google is responsible for the releases. It could be possible that the LTE edition might skip 4.4.4 and jump straight to Android L when it is released. Let’s hope we see something soon, If you need further assistance you can email me with the Case number N140822232 in the subject line for reference.

Dear k3lcior,
There are reports of the Nexus 7 suffering from touch issues, most of these reports have been fixed with a software update. If the updates do not resolve the touch issues, I recommend sending it in to be diagnosed. I would be more than happy to help assist you and all others with our RMA process.
Since your Nexus 7 has already been to our repair facility I may be able to see what other options are available. If you are interested please feel free to email me at [email protected] with your serial number. Also, please put case number # N140822280 in the subject line.
Best regards,
I have bought Nexus 7 (2013) last August and the warranty had been void already. Three of the sensors including the accelerometer, gyroscope and the magnetic sensor do not work properly which causing the malfunction of auto-rotating. I have sent the tablet for RMA process before and the sensors have been replaced. However, the sensors worked for a week only. In the most of the time, the accelerometer and gyroscope look like disabled but the magnetic sensor can return some value although I reboot the machine.
Will the smart cover case affect the sensors by magnetic field? <--I'm just guessing
I cannot figure out the reason why the sensors do not work. Can you give some opinions to me? Thanks

Hello PC323,
I am sorry to hear about three of your sensors failing within a week of the repair. In regards to your question about the smart cover affecting the sensors, there is a very slight possibility, depending on which cover you are using. If you are using the official case for the Nexus 7 then there should be no interference, the magnet that is included should be small enough and placed properly so it does not affect other sensors. I cannot speak about third party covers though. You can always try wiping the cache (done through the recovery) or even a factory reset if you wanted to go that far. If the resets do not resolve you issues then it might be a hardware issue. If you would like you could email me and include case number 140822657 in the subject line for reference. If you provide your Serial Number I will be able to see what was repaired on your device as well.
Hi Scott! Great to see manufacturers represented on the forum! Never seen this before, guess I should have gotten a nexus device sooner. Is there any way we can see phonecall support for the LTE version? I've seen the asus padphone, is our radio missing something hardware wise or is Google/Asus holding back? When I get home from work I go straight from my phone to my nexus 7 but I would love to be able to just pop my sim in and not worry. I'm a job jumper and I need to receive calls on my nexus

Hello,
I am aware that there are some workarounds that involve using google voice and forwarding your calls. To me the easiest option would be to find an application that uses your Nexus 7 as a Bluetooth device. This will allow you to use your tablet to place phone calls and send text messages. I can’t personally recommend an application that will do this but I do know that there are applications that will let you do this. This would not require you to move your sim card form one device to the other. If you need to contact me your personal case number is N140823357.
trade LTE for non LTE?
I was one of the first purchasers of a Transformer Prime and needed solid GPS performance. Asus bought back my Prime and I purchased a TF 700. I replaced my TF-700 with a Nexus 7 2013 LTE so I could get the benefits of having the most current version of the Android OS. Well, we all know how the most expensive LTE model is the "ugly step child" who's updates actually lag behind non Nexus devices.
I am trying to stay positive here but this level of support isn't what we have been led to expect for Nexus devices. Is it possible to exchange a Nexus 7 2013 LTE for a non LTE model?
With the exception of the uber late updates to the tablet I truly love it. The most expensive model shouldn't be the Cinderella.
Scott, my N7 2013 doesn't get recognised by PC when connected via USB. What may the issue? It is very frustrating. Gives me USB device not recognised(port reset failed) message every time I connect it any PC(I have tried connecting it to a few) using different cables.

Scott,
I saw your post and am taking you up on your offer.
Her's my story so far:
I called Asus this morning to inquire about replacing the USB port on a Nexus 7. After quite some time with the rep all he could say was the estimate was around $200 but it could come up cheaper depending on what the technician finds.
I know the problem with my sons Nexus 7 is simply the USB port needs to be replaced because the tablet still functions 100% in every way. The only issue I have is that when he plugs in the charging cable it will simply fall out. He has to make sure it stays in and not touch or move the tablet while it is charging. There is no need to troubleshoot, only to replace that USB connector part. I see the part on ebay ranging from $44 to $75, but I prefer to have the manufacturer repair my device as opposed to doing it myself or third party. Can you advise me if I can get a more solid price please as I feel that before I spend $200 to repair my sons almost 2 year old tablet I'd sooner replace it. If I replace it, it's likely I may choose the manufacturer that has been supporting me the best, and at the moment that is not Asus. Is this something you can help me with please? Thanks
Probably you can pinch the port .... They seem to open up and get loose pinch it down with a flat head and moderate pressure ..... Worth a try

Hi! My nexus have problem with wifi. When i download apps from google play, speed is about 0.2-0.3 mb/s. It's very slow. On my phone is 1.0-1.5 mb/s. Chrome and others works great. Is this issue in hardware or software?

Component on Nexus 5x motherboard

Can you please tell me the part number of this chip , or what is its function please ?
Thanks in advance,

Motherboard change with upgrade to LTE

Hello everyone,
the motherboard of my S4 mini duos (i9192) failed, probably the EMMC, and I need to replace it. Since where I live the 4G/LTE signal is so much better than the 3G and I don't need the dual SIM anymore, I was thinking to buy the i9195 motherboard and substitute it for the original one.
When looking at the components of my phone, I saw two other parts which seem to be related to the 3G version (i9190/2, as written on top of them): the USB connector board and the antenna on the top part of the back housing (the one with "3G" stamped on it), see the figures here.
So I suppose that I should be fine by replacing all three pieces with the i9195 version, also given that they seem to be the only 4G-related pieces in the phone, as per this thread and the video linked therein.
Has anyone tried this? Or, do you have any comment/advice?
Thanks in advance!

it is a gamble I think, it has been reported that even swapping the connector brd for a new one sometimes didn't work with older motherboard, though swapping all 3 it might work for you, but no guarantee. Also then you might have problem loading software & need jtag
But is there much of a price difference to buying a new phone?
Ok, I bought an i9195 used mainboard together with the USB connector board for 30 €, mounted them and flashed the latest Resurrection Remix. The phone is working pretty well (a really big upgrade from my S3 mini) even without changing the middle frame. Actually, what is missing on the middle frame is the 4G antenna, so the 4G is not working at the moment, but for the rest no problems whatsoever.
I'll try to buy the middle frame in the future and report if the 4G starts working, or if the circuitry got fried for the lack of the antenna.
@IronRoo thanks for the suggestion, the main point going for a new phone is the price of one with screen size less than 5" (this is 4.7" and is perfect, bigger ones are uncomfortable to hold for me): the cheapest one is Samsung A3 which is 200 € at the moment. Also, I'm also kinda annoyed by throwing away a phone that could be fixed and given new life.
Strange... My 9192 also fail EMMC some months ago and I also replaced it to 9195 from a local shop. It just 2 case of failing EMMC is seems like a design flaw? Maybe?
Anyways my phone is fine except for battery life I don't get even 1 full hour in performance mood also on RR ROM android 7, and it's my secondary device so I don't use 4G on this device can't report back how good probably I won't even get bit of charge xD

A50 unreponsive touch screen, no sound and no mic.

I have a A50 (SM-A505GT, Brazil) with Android 11 (U7) with an unresponsive touchscreen, no sound and no mic. This problem happened last thursday, april the 29th. Last year this phone had its AMOLED screen replaced with an aftermarket one, after got the original broken. When I say screen I meant screen and touch, they come in one single unit.
To test the touchscreen, I swapped the installed screen with a new one but the touch kept unresponsive. Using ODIN, I also tried to install the newest ROM and after that tried to downgrade to Android 10. Both binary 7, but without success.
I already bought a new phone but this thing keeps itching to know what happened. So, does anybody have any clue what's going on with this phone?
Can a software problem cause the touchscreen to stop working even after a fresh ROM installed? Or this could be a hardware problem in a subsystem of the phone interfering with all that?
Thanks in advance!
Same issue here. I replaced my screen last year (A505W) without issue. I was happily using my phone again until Samsung forced an OTA update and now my new screen no longer responds to touch. I will never buy a Samsung product again. :/
