Lollipop lockscreen font corruption - Galaxy S 4 Q&A, Help & Troubleshooting

I have started to get corruption of the alphabetic characters on my 'secured by pin' lock screen, not immediately but after days of use. I'm using i9505 with stock lollipop .
Is this a samsung or google issue, or just a symptom of the more widespread memory leaks and overwrites lollipop suffers from?

In my S4 (i9505) this don't occur but in my boss S4 this occur.
Somebody find a fix for this?
Or at least know what is causing this.

me too - experience today on my S4 LP. Device had not been rebooted for ages, reboot sorted it but will keep an eye on it.
Anyone else seen it or any ideas ?

It gets even worse if you don't reboot. On my Galaxy S5, all of my lock screen notifications and the notification bar are now corrupted. I've tried changing fonts, but I can't come up with a solution other than a reboot. It's probably a Samsung memory leak.

I have had the same issue with my S5 since upgrading to Lollipop. I have watched the corruption slowly take over my lock screen - the more I need to enter my lock screen password the quicker the rate of font corruption. This will happen every 2-3 weeks and can only be "fixed" by rebooting. Changing the font did nothing to fix this.

Same problem here, Galaxy S5 in US (Verizon Wireless).
Phone is encrypted if it matters.

Having the same issues... So annoying.
If you look closely at the screen shot, the fonts aren't corrupt, they are just being occluded by those rectangular shapes (you can see the proper drop shadows for the characters underneath). It's almost like a clipping our bounding box error or something.

Bump!
Anyone has a solution except reboot?

dead center... I've searched searched for a solution but haven found it-can you help?

Ok my screen works, alignment is whack because the CENTER of screen doesnt work. I have seen a few people have had same problem but saw no results that worked. so open invitation to those that are skilled.
KJAM with WM6
Problem: the exact center of the screen does not work, its about exactly 1 centimeter to each extreme. on screen alignment it takes about 10 tries to finally exit alignment mode, *i dont know if its tired of trying to align it, that it just gives up* but screen center still does not work. everything else is fine but it doesnt work.
Tested the problem: to see the exact affected area i went into notes with draw mode. i made tons of horizontal and vertical lines through the inner part of the screen to see which was th area that didnt work. and it looks like this.

[Q] Nexus 7 White Dot?

Hey guys,
When I turned on my Nexus 7 the other day, I noticed what looked like a white fingerprint against the screen, like someone had pressed against it too hard (no one had, it was sitting perfectly safe), and I had never seen this kind of problem before, so I thought I'd come here. I have two pictures of it. They aren't the best, but you can see the problem in them. Any ideas on what it is, and how to fix it?

That looks like a fissure or an unprecisely-shaped grid of dead pixels. Do you get that upon boot?

It had been dead for some time, but once I recharged and booted it up, I noticed it. It hadn't been there before, and I haven't tried resetting the tablet.

That would appear to be an issue with the hardware then, unfortunately. I don't think a reset will do anything if you noticed it as soon as you booted since it appears before the OS even started. Has the size or shape changed at all since you first noticed it? Does *gently* bending the tablet in any direction affect its appearance?

So, I just got an update notification on my Boost Aquos Crystal

Is this a stage fright patch? Or a lollipop update? I rather stay on kitkat since lollipop was a mess. I use it as a wifi device and its never been connected to Boost.
Here's the end result
The update hangs quite a bit around 77%-90% (phase 1) then it goes into phase 2 and finishes the update.
strange I can't find info about this patch ..
are you seen something new after update?

me neither. if you can tell by the timestamps on my screenshots i was looking all over the place. it is snappier but that could be a placebo. also, i don't know about call quality or mobile data since i basically use it as an iPod.

I search in sharp and sprint webpages but there still show s4081 as last update.. for now I will not update my phone bcs I don't want to waste my chances to unlock bootloader or root if some one find a way...
Maybe???
I just got it too my phone won't install it cause me battery is to low but, I'm pretty sure its a patch to fix the multimedia message problems . too small of a file to be lollipop .or maybe it's a straight to SD patch idk probably one of the two..lol.
Just updated. Touch feels more responsive but it usually does after an update. Here's to hoping it doesn't crap out again.
Compared to the last build it has a new kernel. So far the only thing I've noticed, is that instagram doesn't auto play video with sound, (finally!) like it should. Before it would blast the speakers whether you tapped on the video to turn off/on sound.
It fixed my MMS problems.

It's not a hardware problem if it appears on screenshot, so don't worry about that. Maybe it was a facebook related bug.
I've had this happen to me before. That blue thing is the little handlebar that appears when you highlight text. There's a bug where it'll appear in the corner of your screen for some reason.
It's a Messenger bug! Try to close it & it'll disappear ?
It disappears when you optimize your S7! I want to believe that it's a cute way Android is using to tell us that the device isn't 100% optimized. It kinda looks like a water droplet. Maybe meant to look like a sweat drop? I dunno. But optimizing or restarting the phone will make it go away
I have the same thing and I was not in Facebook at all when it popped up I was in snapchat and it just popped up when I hit the home button its only on the home screen and you can move it maybe a 1/8th inch and it will go back when you finger is no longer touching the screen I'm on 7.0 and its a at&t galaxy s7 not the edge the normal one

s7 Edge Bootloader Exception - Any key combination not working / cannot go to DL mode

Hi,
does anyone encounter this bootloader exception that has pure red letters (no greens like others) and any combination like Vol - plus home plus power ain't working and other key combination?
I also drained the battery and after plugging in, the bootloader exception just appears with other text but still pure red letters, still no response.
I cannot flash anything because I cannot enter download mode. Is there any way which I can do? Please see below for the reference picture.
(I have posted a new thread since the other thread has access on download mode and everything)

None. I went to service center and they said Main board has to be changed But I'm going to try some luck tomorrow to fix with the cheaper guys who will try to reprogram and will open the back to do some stuff. wish me luck
Any NEWS??
I have the same problem, but with i little different error error codes. Phone not responding whatever i press.
Damm, mine did this last night, i guess all contacts and everything is lost now
So, i just got the phone from warranty service and they replaced motherboard, so it means that this was hardware problem.
