Develop Bugs

[Q] Where did my lockscreen go?!

When I was using my phone today, I noticed that a long press on the power button was shutting down the phone instead of bringing up the menu. Then, I realized that I had also lost my lock screen, which I really hadn't noticed because I don't use the pattern lock. Turns out, even if I enabled the pattern lock, password, or PIN, using the power button still took the phone straight into the home screen.
I don't know if it was an bug in a random app, malware, or what... I spent a lot of time searching for an answer on what might have caused it, but didn't find anything really helpful. I started deleting all my recent apps, but couldn't get the lock screen back, so I ended up restoring the phone to factory settings and starting from scratch.
The only reason I'm posting about it is that I'm not entirely sure what caused it... I'm debating the possibility that it could it could be a touchwiz bug. Anyone else ever run into this?

Yes, its a known bug. I just ran into the bug today and I refuse to do a factory reset to fix the issue since its just gonna happen again. Samsung should be able to fix it with a simple software update.

No, so far the only way known to temporarily fix the issue is to do a master reset.

Ah, that would explain it... I was tearing out my hair trying to figure out what I had done. Funny thing is, I don't even *like* having a lock screen. I was just bothered by the fact something was wrong...
How did you find out that it's a known bug? I must have been phrasing my search poorly, because I couldn't find squat about the issue.
Still, whether I like the screen lock or not, I think this is a pretty decent security bug, considering it removes the ability to lock the phone...

I know because I seen it under "list of known issues". If you scroll down a few post you'll find it. The downside to not having a lockscreen is that if you receive a text message your phone will automatically unlock and you may accidentally dial someone if the phone is in your pocket.

FOR THOSE OF YOU WITH THE LOCKSCREEN ISSUE I ADVISE USING A 3RD PARTY LOCKSCREEN. I AM CURRENTLY USING "AGILE LOCKSCREEN" (WHICH CAN BE FOUND IN THE ANDROID MARKET). I AM USING THE PRO VERSION, BUT THE FREE ONE WILL DO THE JOB ALSO.
Sent from my SGH-T989 using xda premium

Mine's gone too.... Now that we have root I've a nandroid backup which I believe still had the lockscreen and will try restoring from that. If that doesn't work then I guess I'll do a master reset and restore from Titanium Backup. Hopefully Clockwork Recovery will survive the master reset...

I thought that was just me yesterday so I did a master reset

I was thinking the complete opposite. I installed ripple lock and that's when i started having the problem. Uninstalling didn't help. As soon as i uninstalled and a factory reset, haven't had any issues since.

No, its definitely a software bug. I don't advise doing a master reset because the issue will continue to happen.

For people having issues of making calls/etc. when the screen unlocks:
Just put the phone in your pocket with the screen facing AWAY from your body.

I had this happen immediately after using the *#0*# test screen, I'm blaming that

this sounds like a bug
it shouldn't need that, as in the lock screen shouldn't even dissapear
i'll suggest everyone experiencing this bug to report it directly to samsung, so they can fix it

Instagram Problem.

For some reason, I was trying to put up a picture that I recently took from my S4, but it kept getting messed up, one was with black background and the whole picture was black. that's all. Then one was white so it was pixelated. So I told my friend to put it up and i Sent him it and he put it up on my account with no problem. Are any of you guys facing this problem? And if so any solutions?

Just sent a picture I took earlier through, came out fine for me. Did you use the instagram camera or the built in one?

I had the same problem... tried posting a pic of the galaxy s4 box and a black pixelated picture kept coming up

Same case.

There is an update, but I think it was more so for international users mostly. When in doubt, delete app and reinstall, that would be my suggestion, reboot if needed first.

Try another pic of the same or something black, see what happens. If it happens, maybe something wrong with color recognition, doesn't this device have a setting for RGB in there somewhere? Too new now to know of common problems, good thing for warranty and forums like XDA !

Tried alot, and IDK and yes thank for warranties and XDA

Sorry I couldn't be of much help, if it is just isolated to Instagram only, it may be app/device incompatibility would be my bets guess. However, with it running 4.2.2, that almost makes me think it is on the apps dev side. An update from Instagram may resolve it, or email dev of app.

Ever since update I'm getting the same thing

Can you two provide a pic? I am on 4.2.2. (mind you, also on a SGS2), and I updated IG and I am not experiencing this. It may be device related, ruling out 4.2.2, but again, I am AOKP, not TW. Root that bad boy, the devs will have great ROMs for this beast of a phone.

[Q] (FIXED) Screen Rotation Reversed

Hey folks. I've mostly been a lurker around here for a number of years and never posted but I've recently encountered a problem I can't seem to fix on my own. Here's some basic info.
Galaxy S4 (SGH-M919)
Stock ROM (rooted)
Android 4.2.2
BB Version M919UVUAMDL
Kernel Version 3.4.0_562219
Recovery Clockwork Mod Touch
The problem I'm having is that I have to leave my phone with auto rotation off. If I turn it on, landscape and portrait rotations are 180 degrees off, flipped, upside down, etc etc. I've been searching high and low for some way to fix this and no dice! Please let me know what I can do. I have tried accelerometer recalibration and a few apps but I just can't get it to work right.I would like to avoid a re-wipe. I finally have everything just right. Wipes irritate the heck out of me because I guess Clockwork Recovery can't access backups on the external SD card? Ugh.
Problem: flipped screen, camera up side down, camera flipped, screen 180, screen upside down. Reverse portrait, reverse landscape.
Fix: Had bad kernel. Flashed to a newer ktoonz kernel and it fixed the problem.

BTW: I just realized that my camera is also in fact flipped 180. Sheesh. This is a royal pain.

Are you perhaps using a kernel not meant for tmobile? I ported roms for the galaxy s 3 and they always did that unless you used a kernel meant for your devicce.

Im not sure what lernel that is im sorry.just got my s4. But anyhow is it a custom kernel that you flashed? If so make sure you got it from a tmobile thread. Or if you would rather it maybe easier to flash a tmobile kernel such as ktoonz and see if that fixes the issue.

Just figured out its a custom ktoonz kernel. Replaced it with old stock kernel with suid removed and problem seems fixed by my sd card went south when I did. Cant mount it. Copying files off it now.

I am seeing the reversed auto rotation on my wife's GS4(SPH-L720) and it is stock unrooted. She has made no changes to anything! Camera and menu's are upside down. Web pages are upside down. She needs to keep auto-rotation off, just to use it! Others online with the same problem have been doing factory resets with no luck. One person did 3 or 4 factory resets and still has the same problem. My rooted GS4 is ok (so far) but hers (not rooted) is driving her nuts. She will never root hers (and would be angry with me if she knew mine was rooted). Any help at all would be appreciated.

If it is stock and unroofed the only explanation would be hardware IMO..... There isn't another explanation especially if a factory reset doesn't help it.

Buttons not functioning

Anyone ever have the home, menu, back, and search keys not function properly? Doesn't seem to be an issue with the ROM as I have tried a couple and have the problem on both all of a sudden.
By not function properly, I mean not function at all. Hitting those buttons has no effect.
Any ideas?

Started happening on ascension oblivion after about 3 weeks of using the ROM. Switched to chillybeans cm10.1 to see if that would fix it but no luck. I have also tried doing a few full wipes and reinstalling both ROMs.
Thinking about going back to stock to see if that fixes it, but really don't want to.

Is it possible that the buttons not working is a hardware issue?

Do you have a screen protector on? I've never heard of em having issues though sorry to say.. of course i twist mine a little side to side outta boredom.. Semi take it apart you might have dust or dirt in there

No, don't have a screen protector on. I haven't heard of them not working either. Unfortunately, my phone is my only source of internet access for the next few days. So its not easy to do much research.

I didn't know stock Touchwiz allowed landscape rotation without tweaks. Of course, that's usually one of the first thing I dump in favor of Nova or Apex anyway.

Wait... Are we talking rotation on the homescreen with no apps open? TouchWiz never did that. At least not stock out of the box. If were talking within apps then yes, it should rotate, if you have it enabled in the settings. Otherwise it will stay in portrait (or landscape) at all times.

I am having the same issue with both the odin and flashable versions. It works for a while, but then stops working. Really annoying! I am not using the exposed framework or modules, purely stock. Are you removing any apps? That is the only thing I do, but nothing I know to be related.

I'm not sure if this is it, or my "fix" will help, but maybe when updating to KK the phone wasn't level, and the compass/gyroscope calibrated itself to be off center. I don't have any issues with rotation, but what I did when I updated was I opened Bubble Level, and noticed it wasn't "level", so I reset the calibrations for the entire phone, and then put it on a level surface, and re-calibrated it, and now when I open the app on a level surface it is spot on. Maybe give that a try. Here is the app I used.

It's funny because that app and the camera app rotate just fine, but nothing else does; not gallery, chrome or anything else I try that regularly rotates. It's definitely wanam or xposed, ran fine until I installed them.

I still have rotation issues. I found with youtube if you make it full screen it will automatically rotate, but you have to hold it all weird for it to stay in landscape lol.

I don't think is wanam or xposed. It must have something to do with an app that I am uninstalling with Titanium Backup. I am currently running Vision X N3 - Tmobile and have been doing some testing. If I uninstall my usual 60 apps that that include S Health and the related sensor app, my auto rotation will stop working. However, if i don't debloat then no issues. I have been running the bloated version for a day or so and rotation still works. I am going to try leaving S health and the related sensor app to see what happens. On 4.3 I would always remove both apps and never had an issue. Oh, and wanam and xposed are pre-installed on the rom. I don't use them, but they are pre-installed.
So, do you debloat, and if so; do you remove S health and its related sensor app?
