Exchange for another one.

If this is a stock tab and you have made no changes, then I would agree that you should take it back. However, if you modified it in anyway, then you need to go back to OEM stock rom.

[Q] Screen dead on incoming calls(lock problems, among others).. only on roaming ?

Well .. Now here's what .. When I'm on roaming ...
The screen at times, doesn't unlock ..
hitting any button (including the unlock button) yields to nothing.. the screen just won't turn on ..
After repeatedly jamming some keys .. the screen unlocks. .. and everything works just fine .. till the next time, which could happen at anytime :/
What's sad is .. that my Wave's LCD , at times, doesn't even turn on while receiving calls..
What's up with this ??
There's also a ton of other issues..
I'm running 1.2 bada..
The phone just reboots randomly from the home-screen
The interface gets REAL laggy at times.. with nothing in the background.
Also , SIM REFRESHING Esp. just as a call drops out .. the network'll go offline for anything like 5-10 minutes!!
This is rendering the phone unusable!!
Am off to the service center to ask the m for a fix/replacement/ credit note
Just don't know what to say to them!
If any1 lives in India , any Idea of how the Samsung RMA system works ?? I've had to put up with hell when I got my HTC fixed in Okhla
+thanks to all those who contribute
Maybe you can reset your phone before giving it Samsung service center
That can be done from the settings menu
Best Regards
HEY!
Thanks for the reply !!
Well , the whole point was to simply get a new phone.. I'm going to try to get it swapped out for an S or a credit note..
The problem being-- I've been with bada long enough , and I refuse to wait even another month for the 2.0. I have another wave 2 at home , so can flash that and see how things work out later.. but for the time being , I need to get rid of this phone.
It's OBV. a software problem that manifests as a hardware problem.. at least it seems so
Anyway ,. my two months in Delhi have been marred by this phone virtually packing up as and when it likes.. so it's time to get a move on.
Just wanted to check whether mine was an isolated case, or whether these were permanent flaws in the device..
I did factory reset my phone after I installed 1.2 ( even that was not without heartache ) . Didn't help on my weekend trips out of station at all..

[Q] Samsung Tab 3 Screen Issue after Rooting & Recovery

First of all, I deeply apologize if this kind of issue has been brought up before. But right now I'm in such a nervous wreck that I can barely search for similar topics for help.
Here is what happened. I tried to root my Android Samsung Galaxy Tab 3. 7 because I heard of all the good stories and satisfaction behind it. Shame on me, I really shouldn't have tried to do something like that when I have no experience with that type of stuff. So after following the instructions, I rooted my device. Then when I turned it back on, the first thing I noticed was:
- The startup had the Samsung logo on it, but there was no ''animation"
- The screen became VERY dim
- The colors were all strange
- There was slight flickering of the screen
I then went here because reportedly that will solve the screen issue, but after downloading the recovery file through zip, nothing's changed. I realized that you also need to download the RocketTab3.1.zip, but at this point, I'm so distraught over what's happened to my tablet that all I want is to unroot, and go back to the bright screen, and the way it was, even if it means that all my saved information will be erased.
I even tried to go to settings - reset to factory settings. All my saved info is gone (which at this point, I don't even care), and the tablet is just like how it was when I first received it - except it STILL has the screen problems.
Can someone please, please, help me? If I can get my tablet back to the condition is was before, I'm never going to try to root again. It's just not worth the anxiety I'm feeling right now..

Nevermind! I fixed my tablet by using Odin and a firmwire! Phew, I barely slept last night, and now my peace of mind is back. Sure, I have to reinstall my favorite apps, but you know what? I couldn't care less as long as my beautiful tablet is working as it should again.

SM-N7505 Wi-Fi not turning on

Hi everyone,
I'm having serious problems with my Wi-Fi on my Samsung Galaxy Note 3 Neo (SM-N7505). Whenever I click the button to activate the Wi-Fi, the icon goes from grey to a dull green (darker than the bright green which signals that a function is turned on), as it does when it's trying to turn itself on. Problem is, instead of turning on, it just stays in that state for a few minutes before reverting to grey. This has gone on for a while, and I've already tried several possible solutions which I found after online searches. I don't think it's a hardware issue (see point 1 for the reason), and I really hope it isn't, because my warranty has been voided due to rooting, so I can't have my phone replaced or repaired unless I pay for it (which I can't at the moment). So, I'm basically ignoring the possibility of hardware failure and trying every possible software solution, hoping one of them will work, otherwise I'm just stuck with no Wi-Fi. These are the fixes I've tried:
1) Take out the battery while the phone is on, wait a few seconds, then put it back in and boot the phone up. This used to work when the problem first presented itself a few months ago (which is why I don't think it's a hardware issue), and I've been since using this method to fix it whenever it happened again. But a few days ago, this method stopped working for whatever reason, so I was back to square one.
2) I tried renaming the data/misc/wifi/wpa_supplicant.conf file, which seems to have worked for some people, but not for me.
3) I tried updating the version from Kitkat to the recent Lollipop, hoping that would fix it, but nope.
4) I tried deleting practically every single app one by one, hoping that one of them was interfering with the Wi-Fi somehow, but nope.
5) As a last resort, I tried a factory reset, but not even that worked.
This is basically the long and short of what I've tried to fix this... I might've skipped a few of the simpler fixes I tried (for example, I just remember I tried disabling "Smart Network Switch", which seemed to do it for some people), but the big stuff is all there.
I'd really like to get my Wi-Fi back, so if anyone could help me fix this thing I'd be really grateful!
Thanks in advance to anyone who will bother to reply.
