I've sold the 'fixed' phone and bought a non-fixed, geniune one (though also used).
The experienced fixers told me the lcd being put in place of originals, are not 10% compatiblewith stock ones, WM deals with this, but android does not.

[Q] Component missing i9001

Hey guys! I just bought myself an I9001 Galaxy S Plus from someone (second hand)... It's my first smartphone so i think i've been busted.
The phone seemed to work well, and everything was ok. But when I try to use the GPS (without internet connection), it does'n seem to find any server. I've changed some different ROMs with different Kernels, but it still can't reach any server.
I forgot to mention that with some ROMs the signal level is very oscillating...
Today i was looking at the phone and observed that there is a hole just above the battery where some component, like an antenna or something is missing. I don't know what component is that...
I think that the missing component is the one in te next picture. But what is its name and role? Instead of it, at my phone, there's a soildered wire... This trick was made to mask other issues of the phone? (if i replace the missing component the phone might have problems?)
I'll attach the photos, may be you can help me. Thanks!!!
Does anybody know?

I think it's a Connector coaxial, a micro miniature form of RF coaxial connector. Look at one i marked with an arrow.. You can replace that part from samsung service center
Best of luck.
The details:
Design LOC: RFS100
SEC CODE: 3705-001731
Description: CONNECTOR-COAXIAL
thank you!
but that's the reason why my gps doesn't work?
or that's the reason why the signal level is very oscillating when i'm using some custom ROMs?
do I need it, or i can live without ?

May be. Not sure..
I used to have a i9000B wich is basicaly the same device.
THE GPS signal simply sucks, it was so bad that sometimes it took 2 minutes to lock in open field, with some roms it got better with other even worse.
I used GPS AIDS with that device an app that was developed just to try to solve this particular device problem at that time. look it up, maybe it can help a little bit, but i thing this device will never get a high speed gps lock.

I know that its GPS sucks, but mine effectively sees nothing. no server
Am i blind, or my antenna is missing completely?
No. Sorry, the antenna is there. I don't know what my problem is with the GPS.
Doesn't seem like there is anything missing. GPS on this was really bad. I never got a GPS signal.

Dont know about OTG, but wifi signal is very good (better than my old sony xperia sola). i had problem with GPS, did a hell lot of tweaking and reading nothing helped... then stumbled upon a forum saying that SMS car can cause problems, and by removing card>starting phone without sms card>shutdown>reinserting card solved my GPS problem...
about GPS fix... it seems its ok, nothing special. just in the middle i suppose.

I have the phone. I think it is very good for its price :good:. Wifi reception very good, GPS normal, USB-OTG is not there. The only minor thing is the camera which does not make clear pictures and is only 5MP I think, although it stores pictures in as much as 12MP, but those are not sharp.
Camera quality JK11?
Thanks for the remarks about this phone, interested in buying it perhaps. Could someone pls upload some photo samples of it to judge camera quality? Or describe how photo quality compares to a mainstream digital camera?
Thanks!
Does anybody know a valid firmware (rom) or kernel, or modem,..... for JK11 that it get better wifi signal than stock rom? It spents a lot of time to load web pages.

Multitouch Issues

Hey all,
I'm having a few issues with my multitouch. Firstly using a multitouch app it picks up all of the fingers a different inputs but they flicker unless you're moving your hand around, so it's impossible to use it for games and such. I'm fairly certain that this is a hardware issue. Although it doesn't seem like it's completely broken as I can still register multiple touches, its just impossible to have continuous multiple touches. Any idea on how to fix this?

It should still be under warranty if you haven't rooted it. So I guess you should take advantage of it.
Sounds like the calibration for the active digitizer for your device needs to be recalibrated.

There are some apps for it.
I tried a few of these apps to no avail. I'm going to have to assume its a hardware issue. unless theres any more ideas.

Most probably it's a hardware problem.
Could it be that it's a lose connection? Or do you think the whole screen and digitizer assembly will require replacing.

Enter *#*#2664#*#* into the dialer to run the Touchscreen diagnostic test to see if your device's active digitizer is really to blame. I don't know the code that will recalibrate the active digitizer of your device. You would probably have to send your device to Honor to get it recalibrated.

This code doesn't do anything. I'm not sure Huawei will be willing to do anything as I have unlocked the bootloader for root.
