So my phone was working fine until it fell on my foot from a small distance and the screen turned to a default lock screen, but i can't emergency dial or do anything it is just a blank screen with the time. i did a factory reset, i wiped the cache a bunch of times, nothing works but a reset.
It seems to be a hardware failure. Maybe you have to get contact with Customer Service Center.

Hi everyone,
Last night my polaris started playing tricks on me. Basically the touch screen is not responsive but the hard buttons all work. For some reason though when I try to do a hard reset (GPS, Internet and reset) it doesn't perform a hardreset. Also I can't put it into boot loader mode
Any suggestions?
Can you try and flash a new ROM?
Yes i've flashed another cooked ROM and till nothing, even D/L official 6.1 ROM and still no touch screen.
I would immediately assume the touch screen is broken but the fact I can't use the hard reset combination (even though the individual buttons work) has got me confused
Hi!
I've the same issue.
This morning everything was fine but, now i can't use the touch screen.
It seems that the "cursors" is always in the upper right corner, but as i move it clicking in the other part of the screen it runs back in that corner.
I'm not able to hard reset, i've tried to do a clearstorage but i'm not able to enter the security code "1234" as i haven't the cotnroll of the screen
Have you solved this problem?
I will let you know shortly but cut a long story short it looks like i broke it
on closer inspection of can see a small dent/scratch on the screen so ordered a new touch screen off ebay. It arrived today so i'll be putting it in shortly so fingers crossed it was actually the problem. I figure the problem was the screen causing a permanent short and hence interupting my attempts at a hard reset
The screen cost about $35 AUD delivered and it took me about 30 minutes to pull the device apart, just have to see how long it takes to get it back together now
I'll post back soon
To me something similar has hapened.
Once i was changing the values of the pressure settings and the screen become unresponsive!
It was quite easy to fix it:
-just press the GPS button and the center button at the same time, then you will enter the menu were you can align the screen and, at the same time, the pressure registry values become as default.
Hope this helps with your problem, good luck with the screen replacement!
It's alive!!!!
Replaced the digitizer (touch screen) and all works again ...
Just to warn you though it isn't for the faint of heart, I thought i'd broke it a couple of times throughout the repair, next time i'll be getting a repair quote first
Congratulations!!
As my polaris is still under warranty i'll send my to the official assistance for the touch screen replacement!
Yesterday i've got my Cruise back from assistanza.. thay have replaced the whole mother board and now the touch screen is working
its a good idea to install my mobiler. this lets you control the device using a pc when the touch screen doesn't work. you can then back up your stuff before sending off for repair.
hi, constant problem here.
Anytime I adjust my today screen plugins (selecting, deselecting, removing) and I close the Today Settings window, I return to a scrambled up Today screen.
sometimes my plugins appear overlapping, sometimes they are all gone but for an empty gray window about a quarter of the screen in height. Sometimes they are gone, but the bottom of the screen is never cleared from windows I open.
Second Today works perfectly.
Any ideas what's wrong?
I have to soft reset, and often do a backup restore to return to normal, sometimes this takes an hour.
Help, please?
worse!
Now even soft reset doesn't help!!!!
This issue make absolutely no sense to me, and only started yesterday.
First, I am stock, unrooted, no mods, no crazy sideloaded apps, just a good old Nexus 5.
When I go to wake the phone, I have noticed that the lock screen is 100% unresponsive. I cannot enter a pattern lock. I then switched to a PIN lock, thinking maybe there was an issue with the pattern. Again, unresponsive screen. So I took my screen lock off completely, thinking there is maybe an issue with the lock screen in general. Again, even with no lock screen, I cannot swipe screens, open apps, nothing. This also includes the soft keys at the bottom.
I decide to factory reset my phone. I update only my Google apps, and again notice the same issue. The screen is totally unresponsive, but then 2 white lines will flash at the top, and the screen will work.
Once those white lines flash, the screen is completely responsive like normal, there are no other issues until the phone goes to sleep again. Sometimes the little lines flash 2 seconds after waking up, sometimes 30 seconds, sometimes I have to hard reset the phone.
I also am linking to a YouTube video that I recorded of the issue in case I am not making sense.
So can anyone explain this to me? What could cause this issue on a phone that has never been rooted or flashed or anything?
Thanks in advance for the help!

Weird. Issue. Maybe you should stick everything from your sd to your pc.
And flash a factory image from fresh install from here - https://developers.google.com/android/nexus/images - if you're lucky the drivers maybe corrupt and not the hardware
Sent from my Android 5.0 Nexus 5
Could also be a loose connection. Maybe the flex cable to from your screen wiggled its way out a bit. I've never seen that before on any phone. I'd back everything up and flash a factory image. If the issue persists, contact Google and see if you can RMA the device.
Hi,
My customer brought me a phone after a water damage. He claimed that the phone has been working fine for a few days after being dropped into the water untill it has discharged. Now when connected to the charger it just normally shows battery percentage level and is charging fine, but if try to turn it on it just shows Samsung Logo, vibrate twice, again vibrate twice and turns off.
What I have done:
- i've fully dissasembled the phone and clean everything with isopropyl alcohol (99%) (most of the water damage was on the bottom panel with usb charging and LCD connector, mainboard and batterry looked untouched)
- i've put both boards for an hour onto the 100 Celsius board
- after another 24 hours i've reassembled the phone and the problem remained
- I've replaced usb charging board and cabel between it and main board with working ones (still the same)
- I've reflashed stock ROM for SM-A515F Poland (without CSC)
- wiped cache
Nothing worked. Moreover, when I tried to enter Safe Mode the screen went "static"? It just looked like analog TV when you have no signal. Every restart ended up with this "static screen". However when i enter the recovery or download mode it looked sometimes fine. After another Stock ROM flash "static screen" has no longer showed up, but the device still "turns off" after Samsung logo and 2x2 vibrates.
Right now I'm not really sure if it is software or a hardware issue. Had anyone dealt with something like this? Any advice is welcome
I haven't tried factory reset yet, because the customer has many important photos on the device (with no backup :/)
Have a good day!
P.S. Tomorrow i will replace LCD to check if it's faulty. If don't I'll be looking a way to retrieve photos from this bricked phone. It's locked with Google Account and PIN, has not enabled debugging or anything else. Is it possible to somehow restore photos from this phone? Some way to install CWM without unlocking BL (to prevent data wiping)? Then from CWM i should be able to fire up ADB and pull personal data? Has someone any idea if it is possible?
Hi again,
I was so happy that i've fixed this smartphone for my customer that i've forgot i've wrote here
Finally I was able to fix the phone. Even the screen looked fine in the download/recovery modes it turned out that it's faulty. With new screen phone is starting fine and everything works correctly. Here's the link where i show the old screen and new one and how the phone responds:
Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.
are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?
Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.
did you try in safe mode to exclude some app causing it
Yes, I tried safe mode without success.
i would take it to Samsung repair centre if pos
Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...
i don't think it's virus. fingers crossed it's just software issue
hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!
