[Q] wifi issue galaxy gt-s7560

hi everyone
i have galaxy trend gt-s7560 and the WIFI won't turn on its stuck on "turning on..." i try to flash it with other roms but its the same issue even i use cyanogenmod but its still the same issue
please guys help me to fix it :crying:
please a reply :'(
This is typically an issue with an incorrect kernel or a hardware problem. Recommended to flash the original firmware to the phone via Odin + factory reset (especially coming from CM). If it IS the correct firmware for your phone and it still fails to turn on the wifi, then most likely there is an issue with the wifi chip on the motherboard.

[HELP] Galaxy S3 4.4.4 WiFi !

Hello community,
Trying to get help about Samsung Galaxy S3 unrooted with custum rom (Dirty Unicorns 4.4.4 KitKat) , after installing a custom kitkat rom my wifi seems to be not working.
Finding my own home wifi station pressing to connect it shows: Connecting... and then Saved. I cant connect. Singal from full went only to 1 ! Even when i'm standing near my router.
Sometimes it shows "Obtaining IP Adress..." but still gets back to "Saved" .
Any solutions? Waiting.
EDIT: Done factory and cache wipes! Nothing changed.
if you got a custom rom ,then your phone is rooted . My advice is when you flash a rom read something about it what is good and what is not .
Try to flash a stock rom or other rom to check your wi fi connection ( make sure isn't your wifi router also) if problem persist then is related to hardware.
Actually i read what is good and bad. But in this custom rom doesnt anyone said about wifi connections anything..

WiFi Direct Can't Stay Connected

Hello everyone,
First time poster hoping experts may be able to help.
I have Galaxy S II phone and Galaxy Tab 4 7". I want to hook them up via wi-fi direct. I go through all the steps, connect them, but 2 seconds after connection is established they simply disconnect and start scanning again. No matter which device initiates the connection, or whether there is or isn't wifi AP in range, the result is the same. I've tried deleting WiFi Direct cache and also wipe cache partition but to no avail.
Can anyone suggest any solutions? It's strange that a basic feature of devices of the same manufacturer doesn't work.
The Galaxy Tab 4 is: 4.4.2
The Galaxy S II is: 4.1.2
Thanks in advance!

this is what i have about the phone i don't have a vpn connection with my provider and when i try to look for the settings it's all greyed out see link: https://db.tt/lFZAxI7r
any ideas?
NOTE: it's in dutch
I've found a solution for a mobile data problem with CM13
NOTE:
if you forgot to backup your efc folder and if you have the same problem as me (look at link) this is what u have to do.
U need one phone and use it as hotspot, the galaxy s3 needs to connect with the mobile hotspot and when the galaxy s3 is connected to the hotspot must go to the wwb so some websites and then the phone who has the hotspot enabled needs to shutdown the hotspot while the galaxy s3 is still connected then the galaxy s3 must connect to the internet by itself.
This worked for me, i've restarted the galaxy s3 and i've shutdown the galaxy s3 and i still have the connectivity i hope this help you guys out!
After updated to latest nightly im facing no vibration issue
Would recommend full wipe and Install. I think this might help.
Hit thanks if I helped.

GPS doesn't work

Hi, I'm writing here because the GPS of my phone doesn't work. At home, it doesn't find my position and when I go out, it finds my position but for a few seconds...then it restarts looking for my position. I've already tried to download some apps that can help the GPS but it still doesn't work. In the GPS options I can not choose between modes: only device, battery saving and high precision. ( I think because I have an old version of Android)
I've read in internet that I should activate the location access for the google apps from Google apps location settings, but the GPS still doesn't work.
Below, I'm attaching the screen of my device. I'm writing from a Samsung Galaxy Grand Neo (GT-I9060), with the 4.2.2 jelly bean android firmware.
Sorry for the bad english and please, can you help me?

I have the same problem on my Lenovo Mediatek device about one year. It appeared when I flashed custom rom. I tried factory reset, flashing to stock, but nothing helped. Now I use WiFi and GSM to know my approximate location. Maybe the problem is hardware.

Click to collapse
I use Wi-Fi and GSM, too. But I would know my exact location, but if the problem is hardware, so, there's nothing to do :crying:
