Integrated WiFi on a MDA2- Shoud I do it? What do you think?

Hello folks,
I've been thinking on this.
I think its very possible to install a normal SD WiFi into the device and I remember that someone talked about this in the past but I think the thread got lost in the last DB crash.
Does anyone know or has some info?
I will take the risk in doing this if someone gives me some feedback.
I tore appart my Socket SD WiFi and belive me, it's really small and thin!
I think it's just a matter of soldering the contacts to the correct positions on the slot, but still, i'm not sure what would happen if once soldered I insert a memory card...
Some say that even with the WiFi card turned off but inserted will still draw power from the battery, how true is that?
Any feedback is really appreciated.
TIA,
Rayan

Though it might be interesting for the rest of us, don't do it. It think you will fail. Reasons are:
- there is most likely not enough free space inside the device
- even if there was, the WLAN antenna would then be inside the device, causing all sorts of electromagnetic interference and disturbing the nornam operation of your device. Also, you'd get really bad reception, as the device's cover shields the antenna
- if you solder things to the SD port's PINs, you can no longer insert another SD Card. Well, physically you can, but electrically you then have two SD cards, which will overload the card slot pin drivers; and logically you also have two cards, and when some software talks to "the" card, both will try to respond, causing undefined behavious.
So, unless I missed something very basic (like today being April 1st... ;-)), this sounds like a really bad idea.
Cheers, Daniel

I was thinking of doing this to the Imate Jam which does not have wifi. The XDAIIs has it internal so I dont think it would be that bad. You cant unplug it also and I dont think it uses more power while switch off.
But at the end of the day, its your phone so do what you want, just let us know how you go.
Good luck

Thank you for your feedback!
That's a good point zakeen, however the XDAIIs was meant to be like that.
But I really don't think the interference could be that bad since the WiFi antenna will be just a couple of inches closer to the rest of the hardware. And even though it's not a real test, I already placed my MDA2 close to my WiFi router's antenna and it didn't cause any interference at all... But still I might be wrong and the telephone part of the MDA2 might loose a few reception bars since I plan to place the WiFi module right on top of the cellular antenna... :roll:
I think the real problem resides on what tadzio mentions about the piggy back not working... :?
In terms of space, I'm sure it will fit (I already know my MDA2's internals after several disections in the past!).
Any other ideas?
TIA,
Rayan

Estupendo Rayan, ¡con dos coxxxes!
Hace poco tiempo que estoy pensando en hacer una falsa tarjeta SD que me permita sacar los contactos fuera y experimentar sin tener que abrir la PDA, pero no tengo una SD con wifi (la tengo en formato CF con el backpack)
Pienso que si la antena wifi queda detrás de la cubierta negra no habrá problemas puesto que esa parte no está cromada (por esa razón ahí es donde va la antena GSM)
Wonderful They border, with two xxxxxx! Recently time which I am thinking about making a false SD card that allows me to accede to the contacts and to experiment without having to open the PDA, but do not have a SD with wifi (I have it in CF format with backpack) I think that if the antenna wifi is behind the black cover there are no problems since that part is not chromed (for that reason it is there where antenna GSM goes)

Short changed by my DESIRE

Held out for the desire, as i was informed by orange that it was a UMA handset and would be the answer to all my signal problems at home...
Only to find, i am left floundering in the no signal land still with no UMA!
Any suggestions????

Post in the correct forum maybe?

i would class adding UMA
As a major forward development, and would welcome a patch or external software...

We have not rooted the device yet so cant really do much.
The only things you could do would be to install a different ROM, but this will void your warranty

well if orange promised it would be uma you are perfectly with in your rights to take it back and surely ask for a full refund for mis leading claims

guess his phone is a defected phone, send back for warranty.

Happened to me a couple of days after I bought it. I cleaned the microUSB port and the problem disappeared. Be careful not to bend any of the contacts in there.

Could be a bug with your USB controller on your computer too. In the past, we found that the ipod's had the same issue.

UFF.

Thank you. try

I used a thick needle with a piece of cotton fabric wrapped around one end. Gently rubbed the copper contacts and that was it. It was hard for me to see inside, but I think I saw traces of corrosion before I cleaned it.

I dropped my glide into the toilet, I'm from mexico I do not know if it can be repaired here

Wow that's awful

First I hope there was only water on the toilet...
And depending on how long the phone was on the water it could still work, I'd recommend making sure the phone is off, taking out the battery, and letting everything dry a couple days without trying to turn it on nor connecting it (that may ruin the phone if it still works).
Also, being from Mexico myself, I can tell you that depending on the part of the country you're on, there may be plenty of places to take your phone to be repaired (again depending on how much it was damaged)

leave it more than a day in rice, before I put it near the calefaxion for 2 hours, and today we take the technician tells me ke circuits were fine, thank ke not lit in all that time, only had something ke calculus, which has already been cleaned and well lit, does the touch screen, reads the sim, the horn works just need to check the external memory slot, I'm very happy because I recover my glide

Mysterious taps/touch input on LG G4

So I have this weird problem on my G4.
Every now and then when just doing normal things on the my phone it totally freaks out and all by it self it suddenly starts to tap random parts of the desktop, slides the pages, opens apps, closes apps, goes into calculator and a bunch of buttons are pressed randomly. It's almost like someone has hacked my phone and is trolling me by just tapping randomly on the phone.
Just today when looking at Facebook it closed the app, scrolled down notifications, data was turned off and wifi turned on.
I thought it might have been my screeen protector, bit of moisture in it or something. Took that off and still does it. Took out the battery for a minute and still does it.
It happened a few months ago then nothing for ages and now it's started again this weekend.
Anyone else had this sort of problem. Is it a hack?

I had exactly the same problem with a completly new G4. Somehow I had the feeling it depends on temperature a little as when I was on balcony where it was colder it was more bad then inside the flat. It was pretty bad and appeared most of the times so it was reproducible. After fiddling around some days I exchanged it under warranty. The one what I received now doesn't have this problem anymore

i have the same problem with my LG G4 H815 with Stock Rom modified or not , with Genesys Rom , with Imperium Rom and with CM Based Rom and another Custom Rom
For me this mysterious ghost taps and touchs arrived rarely and randomly with V20D ; i have remove some touch screen speed, presure and reaction tweaks in build.prop and resolv partially this problem for me in Imperium or in Genesys Rom and in my stock tweaked too ^^
sorry for my bad english

Mmmm. So no word whether it is hardware or software based?
I thought it might be limited to when I was connected to internet as it only seemed to do it on WiFi or Data. But it has now done it with no connection.
It might be temp based, but it's pretty hot where I am, and humid. I haven't had it long enough to test it in colder environments.
Hopefully it sorts it self out as I bought it from Topbuy.com and they are pretty bad for warranty claims.

I'm getting phantom touches to the point my G4 is unusable now. However as soon as I put my phone on airport mode I get zero phantom touches.. Seems to me that would indicate its a software bug rather than hardware?

What is the first 3 digits of the serial# ?
this is a screen problem ie hardware from what i understand. Happened with early batches then went quiet.

My phone started doing this while at home, but only when it's plugged in and charging. It may have something to do with the quality of the charger. I keep my OEM charger in the car and I have no problems when I use my phone in the car while charging. My chargers at home all came from eBay and the ghost taps start when I am charging at home and trying to use the phone. I get the problem whether Wi-Fi is on or off using the eBay chargers. I don't use Wi-Fi in the car, but I use Mobile Hotspot a lot without any ghost taps. Hope this helps!

The same problem!
I have the same problem. My G4 is the h815 20A, serial number starts with 505. The ghosts taps started 1 month ago and impair the use of the mobile device. Amazingly, the touches almost disappear when the phone is on the charger. Anyone have any solution for this? What would be the problem?
I think that's no a hack problem. It can be a software or a hardware problem, but i don't know.
Can anyone help me?

Ho il vostro medesimo problema. Talvolta partono anche le chiamate, si spegne la connessione dati e si attiva da solo il Wi-Fi, pagine di Facebook che scorrono da sole. A volte risulta inutilizzabile..

Sounds like water damage or from humidity. I had an iPod do this and fixed it by cleaning the connectors for the touchscreen. What have you to lose in trying? Don't break or void warranty though.

I apologize, I will not do it again.

I solved the problem: I change the touch-screen system. I think that is a hardware problem.

This is a software problem. Many of G4 owners had this ghost touches when the phone was released. An update fixed it later, but now I can confirm LG messed up again as I'm having the same issue with the latest version of the software.

Hi guys,
I have the same problem.
I noticed that it appear a mostly on 2G connection or on LTE when it fall back to 2G or very low signal.
Locking on 3G seem to solve. There's no way to lockLTE.
Tried several roms, with no luck. Do you have any other clues? It's Hardware or Software. Any new kernel or modem can solve it?
here's a video for this. LINK VIDEO
Thank you for your help.

This is not a software problem. This is a hardware digitalizer problem. It's necessary to change the all the touch screen system (digitalizer problem).

I have same problem with H818N, the problem seem to disappear if airplane mode is turned on, it also seem stable when on 3g only, which implies it has something to do with mobile signal. I have tried several things without luck and the thing is I can't easily reproduce it. At times It happens when there is an incoming call or SMS. Any suggestion will be helpful

Having the same problem on an H815 running (yet to be updated) CM14. If the screen has fingerprints or streaks it ghosts like crazy. If I can turn the phone off (before anything disastrous happens) and just give the screen a quick wipe (t-shirt, napkin, whatever), problem fixed! I would say it is definitely related to the hardware of the screen digitizer and random conduction of the greasy finger prints, cheek plants, etc. Cheers

Same problem. G4 H815 602 v20d stock. The problem started when I left the phone in the sun too long while hiking. For me, it only happens when the screen is off so I disabled 'knock on'.
Airplane mode does not help.
