[Q] sm-g9001 WIFI problem after Lollipop. - Galaxy S 5 Q&A, Help & Troubleshooting

I have a Galaxy s5 sm-g9001. After updating to lollipop, I have a problem with WIFI.
It is still connecting and remains stable however I can't browse the internet. I can only open the modem settings page 192.168.1.1.
Does anyone know what the issue can be?

Factory resetting after updating from KK to LP is highly recommended, KK leaves behind rubbish files that cause problems, resetting usually fixes most of them

[Q] Verizon Tab won't perform factory reset

I have a Verizon Galaxy Tab SCH-I800 and I woke up today and it was missing some programs that I had installed the night before. Launcher pro keeps crashing so I had to put the Samsung Launcher back on. Now random programs all keep crashing and locking up the device. I performed a factory reset through settings -> privacy -> perform factory reset.
It restarts and goes to the samsung bootloader and I performed wipedata/factory reset.. It says it does it but when it restarts its in the same condition as before.
I've booted directly to the bootloader and tried it too (volume up and power key). I've also tried to wipe cache with no luck..
Any ideas? Can I root it and put a custom rom on it? I saw that there really aren't any roms for the Verizon tabs.. Any reason why?
Thanks for any help..
I just did a restore with all the stock verizon firmware using heimdall and it flashed and everything went through properly..
I booted into recovery and wiped data/cache and restarted...
SAME THING! It will NOT wipe out my existing data.. It restarts with all of my old programs installed and NOTHING will work.. The OS is hosed. How can I wipe this thing back to factory??

Any luck with this? I'm having the same issue and don't have ODIN setup for it.
Same Issue
Same Issue
I changed my passwords on Facebook, Twitter and Gmail. After about 30 minutes the tablet finally stopped bringing up my information.
Need help!
Same to me...
I've tried to uninstall some apps several time, GTab automatically rebooted and these apps are still there...
Could anyone solve this issue?

I'm in the same boat..half my apps crash when you try to open them. I've wiped the data partition 3 times, and the cache as well..not avail. Apps are still on the device after a master reset!

I had that problem, and I wound up sending it back to Samsung. It appeared to be a bad part on the board, so they replaced it and it's on its way back now. Not the answer you want, I'm sure, but call it in and get your RMA number.

On your new Tab can you perform a hard reset and have it actually work?
my sprint Tab seems to be in the same boat

Factory reset before updating to Lollipop?

Hearing a lot about bugs and battery drains after lollipop update. Read somewhere that factory resetting after the update solves a lot of problem. I was thinking about factory resetting my note 4 both before and after the update. But I've already downloaded the update, now question is will the update be deleted if i factory reset the phone before the update? Anyone?
I haven't reset before installing after downloading but I'm going to assume it will delete the downloaded update. And yeah factory resetting after installing is a good idea, as I haven't had any memory leak issues people have complained about.

if you do it in recovery it should not delete internal storage however just to make sure copy it on pc and save the directory on your phone so you can install it

Problem with my phone..

Guys, when i turn off the wifi the passwords deleting auto.. and when i restart my device some apps deleting also the settings on them.. how to fix this? i am on 5.1.1
Have you tried wiping cache and dalvik cache? Had the same problem and that fixed it for me.
Or just re-flash the entire rom

GPS unusable after May Security update

I updated via the OTA to the May update recently and now my GPS is totally messed up. It generally knows where I am when I start a trip, but then is super slow to update my location, and is a block or two off of my actual location. I tried doing a factory reset but this didn't solve the issue. Any ideas?
Have you tried using GPS Status and Toolbox?
Do this with a working Wi-Fi connection: Settings>>Manage A-GPS State>>Reset. Then within the same menu, hit download.

Only thing left to do now is to backup, wipe all partitions, and load a fresh image. If the problem remains, it is hardware related. I would make sure to fastboot FORMAT userdata, system and cache before flashing the latest full image.
I've noticed that the 7.1.2 is not fullty compatible with the settings that might be hanging around from 7.1.1 (or before).
To get my phone to function properly I had to do a clean install and wipe the phone completely.
before that I had SIM issues and Bluetooth issues.

Wifi and Bluetooth Issue

Please help. I need some advise. My wifi and bluetooth no longer works. It just happened right away while I was watching some youtube videos and it no longer works. I tried clearing cache and data, wiped cached partition, factory reset, network factory reset, flashing a firmware from different country but to no avail. Could this be a hardware problem already?
