Black screen of death after flashing firmware - Samsung Galaxy S7 Edge Questions and Answers

I have the S7 Edge originally the ATT version but I rooted and flashed the unlocked version firmware. I was trying to unroot the device and restore everything to the factory settings since I am using the trade in program through Samsung and have to send it back in stock. I tried to flash it using Zodin, the Mac version of Odin, but was unable to get it to work because I was not able to get the proper pit file, it always returned with the error that there is a corrupt file. Since I do not have Windows, I could not Flash the firmware using Odin. Out of desperation, I looked online and a website (the article was on Android forums with the title restore stock with flashfire no PC) said that I could use the Android app Flashfire to flash a firmware and return to the factory unrooted settings. I downloaded and inputted the full firmware file for the original AT&T firmware version and checked the boxes to wipe boot, system, internal data, and trusted Zone and also maintain everroot. It seemed to work and was processing with the fast scrolling command text on the black screen but after a few minutes it said there was an error at the very bottom of the screen. Eventually, it restarted but nothing has come up and the screen is black without any light from the LED indicator. I tried to restart it with the power button several times, holding down the power button and the volume down, holding down the home button and the power button, and holding down the power button, volume down, and home button. I left the phone unplugged overnight and plugged it in this morning to see if it would turn on but nothing happens. Any help would be greatly appreciated and I am hoping that I did not brick the phone.

Since Im not sure now if you also tryed to go in download mode again but ussualy you are always able to do that.
If not try to remove battery and put it back in after 10 minuts. And connect it to your laptop and let it charge for a few minuts. Next Hold buttons for dowload mode. Hold em for 5 secconds. Even if still have a blackscreen open samsung kies or switch. One of them has the emergency recovery option. It will detect it then and will say something like you need to repair the software want to continue etc. Lwt it do its thing and make sure you are on the internet. You drink some coffee and give it 30 minuts atleast.
Still not work? Try to put in a spare battery or charge it with another phone. If that not even works. I cant help you.

First of all, I do not have a battery that I can remove. I tried to enter download mode and recovery mode but nothing worked. It will not boot up into any mode.

Just hold the button combination for download mode for 10sec and connect it to a PC with installed smart switch on it. Smart switch should detect your phone, even if the display of the phone stays black.

I tried what you recommended but nothing works still.

I seem to have encountered the same problem, albeit not through exactly the same method. Essentially I managed a full stock firmware flash through ODIN, all the right messages came up and I got a pass from Odin. The phone rebooted and brought up the blue "updating" screen, which very quickly changed to a "removing" screen, at which point the phone froze. When I tried to reboot, the screen went black and now.... nothing. No recovery, no download, no light to indicate that its charging... nothing. My computer doesn't register there is even a device attached.
I've done heaps of flashing and never seen anything like this!
Would greatly appreciate any advice or assistance!

same issue here accept i was just using odin like usual. anyone figure this out yet? the phone was not rooted or anything. i had flashed the g935u firmware and then decided to put it back to stock g935t firmware. then it started doing this.

reflash but this time it check nand erase all

NEVVER EVER CHECK NAND ERASE ALL, dont advise others what you don't know yourself. This is for manufacturer and is not intended for repairing, if you nand erase your phone its just a paper weight then, beyond recoverable. But this issue is caused by wrong partitioning i suppose, but still it must go in download mode, try plugging it in when smartswitch is open in pc while holding home+vol down+power , if it wont detect then i suppose its nand failure due to any reason. And motherboard replacement is required.

I recommended it because I had the same experience of the black screen and blue led that lights up and I flashed more than 50 times without any result and the solution that was given to me and which walked it's this one

If it really did nand erased all, your phone wouldn't even boot, your phone working is a proof it isn't nand erased. What people don't understand is that nand isn't the internal memory, its the non volatile memory holding vital info about functioning of phone just like a bios of computer, so if it is erased you are beyond recoverable damage. Here , i must say i dont know if odin can really nand erase all, because if your phone is working, nand is definitely not erased. And as far as what fixed your issues, there must have been some other reason. But for everyone, leave that option empty just to be safe.

I was trying to install 935U firmware in my 935V US verizon s7 edge. After installation completed using odin phone rebooted and showed new sim setting something.... after that it went off and now its turning up.

Ofcourse it doesn't effect S7 edge, because it DOESNOT wipes the nand.. so its not working simply..
On older phones it will wipe nand totally and thats a dead brick..
First search what nand is.. its the non volatile memory.. or simply nand chip .. if you delete it.. your phone won't be a phone anymore.. its the non volatile memory that is equal to a bios of a computer.. delete non volatile memory and your phone is completely dead..
Thanks to the latest phones that don't erase non volatile memory and instead selecting nand erase with s7 edge simply deletes userdata before flashing.. which is equal to a normal hard reset ..

[q] help! Bricked samsung intercept!

Last year(late 2010, maybe mid November), I rooted my phone and flashed recovery with no problem s at all. Some time after that I added Apps2SD and that went smoothly with no problems for about a week. I purchased an 8 GB SD Card for more storage room and after I partitioned it and switched the cards my phone started acting up so i rebooted it. After that I was stuck in a boot loop, so i tried to flash it back to stock but it wouldn't take to it no matter how I tried, whether it be through recovery or SW Update. So then I tried Odin Multi loader(cant remember which version but at the time I made sure it was the one meant for the Intercept) after I flashed it with the Stock through Odin, the phone bricked. Now it will not turn on in any way(recovery or other) the only thing it does do is vibrate when I plug it in to a computer, and it will occasionally show battery life through the touch screen and keyboard buttons by lighting them, but as soon as the it is unplugged it is a brick. I see the little bit of functionality as a little bit of to be able to fix this phone whether through ADB or another function but I desperately need help with this. Can someone please help me fix this phone?
note: I currently have a Samsung Transform as my main phone so if the Intercept can't be helped then it's not that big of a problem.
I have the same problem! Please help!
When you root a phone you put the rom, and recovery onto the sd card. changing sd cards disrupts this process. Put the old sd card in and tell me what happens.
The phone doesnt come on at all
see if you can get it into download mode with the battery out.
Pull battery
connect to computer with usb
vol down + camera + end
If you get into download mode this way flash the stock.tar using SWUpdater.
Nope, it doesnt work, thx though
Ok I've got the same problem with my intercept as well, So i just like to add (maybe its just me) that when i plug my phone to the computer the phone shows that its still functions right (without the screen on), I'm able to make calls, and receive them as well (with the touch of the answer button) but just the screen doesn't turn on, AT ALL!, so KJON i don't know if your having the same problem as me but I'm just a noob and i wouldn't know what to do. But there's some ammo if you need it.
I HAVE THE SAME PROBLEM! i dont even know where /sdcard/sdx/zip/ is!
My phone is also a samsung transform and not and intercept and whenever i press vol down+ Power, only the function buttons at the bottoms light up but not the screen
i am a noob.
help?
noooooob here...i didnt wanna start another thread since i have this same problem, so i hope someone reads this..
couple days ago i bricked my sprint intercept i was using SWu and forgot to take the Binary files for the Moment out so now i cant get my phone to DL mode, ive been searching since saturday night and have tried every Button combo posted and nothing, my phone will not turn on and ofcourse it isnt recognized by my pc BUT, ive noticed that only when its plugged in to the computer after trying to power it up several times it´ll vibrate then the 4 touch buttons will react to either the call or end button, also it makes the low battery sound and if i press the camera button it makes the volume sound but i CANT get to download mode, can i bring my phone back or is it done with? help please! and thanks in advance...
well, i would say boot into rrecovery by making the phone off either power button, or remove and replace battery.
next, you will need to press and hold in order: power/end call, call, and volume down.. this should boot recovery mode.
lastly, use the red scroll device to go to reset facory defaults or factory recovery, use common sense while looking. select with clicking and use arrow back button to go back to recovery main, then reboot to system. easy as pie.
Have you tried ODIN or ADB?
I have flashed the Intercept numerous times, soft bricked more than once, I was always able to recover using either the stock bootloader, CWM recovery, or flashing the ROM/Kernel directly using ODIN or ADB.
If you are still having these issues drop me a line and I'll gather some links together that should get you back up and running.
If the phone will not boot at all, even with a charged battery, I would definately try contacting Virgin Mobile and escalating the issue. I've had plenty of luck replacing devices claiming that the device just dropped dead without notice. They are usually good about sending out a replacement phone, and on rare occasions even giving you an upgraded unit if they are out of stock.
Good luck!
Did you use Odin or the swupdater?
Bug difference. Sounds like there's a missing boot loader.

[Q] First blue screen, now boot loop.

Hello XDA-devs forums,
I'm having an issue since yesterday.
I have rooted my Huawei Ideos X5, and it ran fine for a day or so.
However, when my battery ran out it shut down into a completely blue screen.
When I tried booting it again, this just showed me a blue screen as well.
Now, I fixed this issue by connecting the phone to my PC after booting it with the Vol+ and Vol- pressed.
(So you get the pink/purple screen)
However, when I opened the phone on my PC, all I saw was a "239 MB" "empty" space, and it should have ~2GB..
I placed a backup copy I saved of my "image" folder in that 239 MB storage, and it booted.
However, today I hooked it up to my PC again to see if it magically changed..
And I couldn't access the 239 MB space anymore.
When I tried fixing the issue with a reboot of the phone, that just caused it to get stuck in a booting loop.
So now I'm stuck with a phone that keeps trying to boot itself,
and I can't access it on my windows PC.
I can, however, access 4 different folders of the phone on my linux notebook.
Now, my question is: can someone with a good understanding of problems like these please help me out?
I'm getting kind of fed up with it, as I've only got the phone for 2 days now.
Thank you in advance, and thank you for taking the time to read this.
Have you tried removing the battery for 5 minutes and then putting it back in?
After this, what happens when you press VOL+ and Power?
How about if you press VOL+, VOL- and Power, without the USB cable?
Hello Katu, thank you for posting.
Regarding your questions:
Yes, I have tried to take out the battery for 5+ minutes- it didn't change anything to the situation unfortunately..
If I press VOL+ and Power at the same time, the device boots into recovery mode.
In this I have tried to format the device in order to reset it to factory defaults, but this did not help either.
When I press VOL+, VOL- and Power, the phone boots into the pink/purple screen.
Can you try a custom recovery and a custom rom? I want to see if your onboard flash is borked.
u8800,cm7,[email protected]
I had the same when my phone got f*ucked up. Put the image folder, than download official rom, like b138 and install it. then check your imei. There is a change that it will be 0.

Well, I used an original ROM:
U8800 V100R001C00B136(Overseas General version)
And that resulted in the boot.img being corrupted, so I can't even overwrite that anymore.
Also, this is what I see when I hit VOL+, VOL- and Power at the same time to boot into safe mode, and connect it to my PC.

I installed the official B136 rom, and after it rebooted, it would just hang on a black screen.
(it used to show the IDEOS or Android logo when it booted)
Hmm mine came with this Rom
U8800 V100R001C00B135SP01 ( general )
Looking at your name you're from the Netherlands ( so am I )
where did you get this 136 version from ?
I would try to put this one on it
You have to put the 'dload' folder into the root of your SD Card,
then boot into boot-loader, after that it'll automatically flash back to the stock Rom.
1 Format SD card
2 On the SD card, create "dload" folder
3 Put the unzipped Rom into "dload" folder
4 Then boot to bootloader (pink screen)
Yes, mine came with that version as well.
However, I couldn't find it anymore and thus downloaded the version I said earlier.
Also, I did everything as you described, except step 4.
You have to boot to recovery instead of bootloader. (VOL+ and Power)
Anyways, I managed to get ClockworkMod's recovery.img on my phone,
and from there on install a custom ROM on the phone, which magically got it working again - even though it didn't work earlier.
Thank you for reading my thread and taking the time to reply to it.
My issue has been resolved.
just for the record, flashing a stock rom is different from flashing a custom rom..
the 4 steps described by Gman2oo6 is the correct way to flash a stock rom (and it is written clearly in the document that is in the stock rom zip file)
[edit]
step (1) is not a necessary step though..
Yeah, I noticed that.
What I did was format my SDcard with FAT32,
and put a custom rom (update.zip) on the SDcard.
I then booted ClockworksMod Recovery and installed the custom rom from the SDcard.
When I tried installing the stock rom, I just followed the PDF file's instructions that came with the stock rom.
hey i udated to GB 2.3.4 (official)and i didnt like the it cuz the wifif ddnt work and the bluetooth also the DATA so itryed to downgrade to 2.2.2 original official and it did the 2/2 steps intalled and when it restarted it did not want to turn on all that happened was it vibrated and thats all so i left it on like that and when the battery died i plugged it in to the AC and the LED turned on red and the touch kkeys also but not the screen so i really NEED help!
Try to turn it on with lead connected but no battery and see if you can start it.
My battery also went dead flat this morning and I couldn't get it started at all till I tried this. Once I got it started the only thing I could do was quickly pop in the batery and let it charge. Just leave off the cover till you get it going.
I have to add that I did not have the problem of a failed update to deal with but it may at least get you started
i tryed it
nope nothin good happened all that happens is a blank screen with nothin on ,LED is off and the touch keys are off. it justz vibrates and when i put the battery it turn the LED on to red and the touch keys turn on but then like 5 min later the LED and keys turn off

ok heres what i did i wanted to upgrade my phone to the newest version GB 2.3.4.So what i did was download the update and i followed the installation steps i successfully updated to Gb 2.3.4. so like i was checking how it look and the new feature but when i wanted to go on the android market i went to setting and turn on the wifi and it said Error and then i tried the Bluetooth and it said Error also so then i put my SIMs card in and i was like imma use DATA then and when i restarted my phone it had service but no HSPA+ or Edge or GPRS so like i just hatted my phone from their so then i was trying to root it but iddnt know how to do that so like i read this website and i got the UPDATE.APP or 2.2.2 AT&T did the same steps of the installation of BG 2.3.4 and it went to the process and 1/2 stepp good it passed and then 2/2 also passed it installed it and when it said Successively Installed it said Restarting and the scrren turn of and it vibrated and thats all that happened and i left it like that for the whole days and nothing happened
Do u got any idea?
When i connect it to my laptop it says installing drivers .then its says sucesfully installed drivers ready to use. so then i got to Device Manger and i check what has been installed and their it said USB Human interface device and HID-compliant device WHAT DOES THAT MEAN??
Not sure about the HID (human interface device) probably just the way windows sees the device for interfacing with it. With regards to the not booting I have read a lot of people saying that you need to factory reset and clear cache after the upgrade/downgrade. With the phone off, turn it on by long pressing volume+ and power on button till you get the blue recovery screen and from there you can reset factory/ data and also clear the cache. from what I see this should clear up the problem and start up. Please read this thread, it may help you somehow..... http://forum.xda-developers.com/showthread.php?t=1420728
Hope this helps a little
U mean Boot recovery and imma try it and thanks ill check it out

S7 Edge Hardbricked by it's own?

Hi people, something quite terrible happened to my phone when I woke up today. Before I went to sleep the phone worked and was charged by about 40% but some apps were force closing like crazy so I turned off the device before I went to sleep, cuz why not, eh? Then I woke up and turned on the phone and it showed the screen to choose if I want to go into downloading mode, I pressed cancel and the phone shutdown and now it wont turn on.
I tried soft resets, tried to charge it for 10 minutes, but the thing is the phone is like its hard bricked for no apparent reason... even the charge indicator when phone is off doesn't show anymore, no lights, no nothing. Please help me. If anyone has an idea what to do it would be greatly appreciated. It worked this morning, no one else touched the phone. :crying:
if it doesnt boot then its a battery problem, even in hard brick, it has some kind of flights flashing.
if Its hard brick then its paper weight, sorry.

If it's the battery what can I do here at home? At least try? I don't think it's a hardbrick cause I didn't do anything iregular to the phone, it was working before I shut it down and went to sleep. Idk how I hardbricked it by turning it off. :/

well the storage drive could fail, that could be another possibility which if I think about it now that seems to be the case. best bet send it to samsung.
if you plug your phone into your computer and it does not read or register, you really dont have any other choices. This goes for all phones, the forum can help you with soft brick, not something like this, this looks like a hardware failure.

The phone rebooted constantly and force close apps from the day I bought it. I thought it was software issue... I went to my carrier to complain but they said nothing is wrong with the phone (way back few months ago). So my last question is this, can a phone force close apps and restart constantly with a software issue? or does it happen only to devices with hardware issues?

Ok so good news! Today I plugged it in the charger again and it booted! As I see it when I turn it off it doesnt really shut down properly and it stays in some kind of a phase and doesnt let me reset or do anything really... but It drained the battery that it had left and it bugged out. I know this cause I shutted it down again via the android option and its "bricked" again. Now I will wait for it to lose charge again so I can boot it.
Can you please tell me how to properly flash via odin to the latest nougat firmware? The phone was from Vodafone in Germany, few months ago I flashed a Netherlands firmware, then some other one few weeks down the road. Can you please tell me how to flash it back to full stock and what firmware should I download? The model is SM-G935F and the S/N is RF8H61YE4CP. I prevously tried THIS firmware from sammobile. Is this the correct one for my phone? I tried using samsung smart switch but it says "Secure Check Fail : Bootloader" when it tries to emergency restore it in the download mode, and the smart switch software says just error. Also whenever I flashed with Odin, BL never wanted to flash cause of just one file in every BL md5 file and that is the param.bin one, everything else flashes like it should. Please write me a guide on how to flash it properly and "upgrade" everything to the latest version correctly for my phone. (many settings in Odin that I never touched)

i had a simmilar problem i couple months ago when i flashed a custom kernel.
i was overclocking the cpu but caused the phone to freeze actually without being able to to anything
i thougt my battery was dead also
when i charged it nothing came up into the screen also.
you just have to hard reset it but just keep on pressing your volume down button together wih your home button and the power button
it may take lonnger then you can normally do it cuz your phone freezed
but eventually your phone will just reboot into download mode then eand you can hit the volume down button to reboot your phone then

Need Help with S7 Edge (SM-935FD)

Hi! It's my first time making a thread here so guidance is greatly appreciated. Here's how everything started:
I was just casually using my phone (at the time I was using the built-in browser of google assistant, just looking at some news) then suddenly my phone crashed (I've experienced this before every time I was using the google assistant built-in browser, a simple browser can crash this phone?). It just restarted like it normally would, then, after using the phone for a few minutes, it froze again! I waited for it to reboot but now it just powered off and won't turn on (it won't show any sign of life, no logo, not even an icon when I tried to charge). D:
I figured to have it checked by a local technician and when he tried to plug a charger in, a display showed it charged (found it weird but happy at that time). I figured it was the charger so I bought a new one.
So I got home to charge it fully and when I turned it on, it worked normally. However, when I tried to turn my wifi on, notifications popped up and suddenly it froze again! After that, it turned off and when I tried to turn it back on, I got this dreaded red texts on a black screen:
Bootloader exception ( RST_STAT = 0x10000)
Exception: do_handler_sync: DABT_EL1(esr: 0x9600010)
RDX, do not reboot*** ext4_wait_block_bitmap:494: Cannot read block bitpc : 0x8f0261d0 lr : 0x8f02618c sp : 0x8f117fd0
This showed and the phone won't even let me turn it off, so I just waited for the battery to die out. When it did, I tried to charge it again and planned to do a factory reset thinking maybe an app was causing this. I managed to go to the no command icon and manual mode but no factory reset menu showed up (where you navigate using the volume up and down). So I tried to restart but now it died out completely- no button combination would work, it won't charge, no display can be seen. Is it hard bricked?
I tried to wait a whole day thinking I would be able to charge it again, but it has already been three days and I am not able to perform anything.
There it is, I tried to be as detailed as possible. Additional info: I never tried rooting it or flash roms with it, I haven't done anything with the software (or hardware since I am careful) but install apps (officially from the playstore). From how I see it, it's a firmware problem and I was hoping someone here can help me bring my phone back to life. Is this my fault? If I have this repaired, am I the one who should pay for this?
I mainly want to know what the error message means and if there is a way for me to access the phone. (I figured if I have the technician fix this, all they need is a computer with a software that could fix this since it's a problem with the firmware. If that's everything they would do then I could do that too, with your help of course.)
Thanks to all in advance!
Hi. This sounds pretty strange. Technically...it is hard bricked but you can bring it to life. I can tell you what I would do, when I run into such a problem.
ATTENTION: YOU WILL LOOSE ALL OF YOUR DATA EXPECT EXTERNAL SD CARD
First download the newest firmware for your S7 Edge (G-935FD) on SamMobile and unpacking the .zip.
Download Odin in the newest version, open it and put the downloaded files in the right order in Odin (BL, AP, CP and CSC - the files from the firmware from SamMobile has labeling with BL, AP etc.)
Now the tricky part because your phone won't charge and doesn't go on. You have to go in the download mode with your phone (press and hold volume down - home button - power button) than an window appears and press volume up
Connect your phone with your PC (in Odin you can see, that your device is connected) and press start. It will take some time transferring the ROM and your phone will reboot automatically and after some minutes of blinking Samsung logo...the phone should start normally into the SIM card pattern screen.
Now you have a fresh stock ROM installed and everything should work fine again.
But your phone won't get on or will charge...maybe when you connect it to your PC it will charge. Otherwise I see no option to solve your problem. Your phone must charge again that you can go into the download mode and bring your S7 Edge back to life with a clean stock firmware and an working system.

Turned this phone into a brick and I need to fix it!

Hi, so, I got this phone from a friend, and he told me that the phone was working prorperly, but after someone factory resetted it, he wasn't able to set it up. Constant force close pop-ups where showing up while setting it up, and you weren't able to accept terms and conditions (button grayed out). Also, one thing I noticed. The phone got into "Factory Mode". Idk what that is, but it wouldn't let me to enable wifi or bluetooth. That little Factory mode thingy got me really confused. Also, I wanted to boot into recovery mode, and I wasn't able to do so. After turning the phone off, and doing the key combo to boot into recovery, the phone rebooted itself (very showrtly after doing the startup vibration) and after that, it seemd to get into recovery, but it stayed at the android logo with an exclamation sign and after 3 seconds it rebooted itself to system.
After that I said, "well, last thing to try is flashing stock rom again". And I did so. Using the Frija software to download the latest version of android for this phone (and using the corect CSC for this phone (CTI)). I used odin 3.12.7 (wich I knew it works because of previously using it with other phones) to flash the stock rom again. I made sure that only Auto-reboot and F.reset time were checked, and started flashing. After it finished, it got to the samsung logo, but got stuck there. Nothing happened (I left the phone there for like 30 min). I decided to hard-reboot the phone and try to factory-reset it, but after shutting it down, it started to be really hard to make the phone turn on. I had to unplug the battery and wait like 10 mins to try again, and I still wasnt able to boot into recovery mode. It just got stuck at the "Galaxy Core 2" logo.
After that first boot, the phone never got passed the "Galaxy Core 2" logo. Just stuck there. After that, things just begun to get worse. It was also hard to get the phone to get into download mode, most of the time it just stayed at a blackscreen (im not shure if the phone ever turned on, but it never vibrated) and did nothing. I decided to try other versions of odin. Tried with 3.09 and 3.04. Nothing, and after every flash, it got harder and harder to make the phone boot.
At this point, I can hardly get the phone into download mode, and if I do so, sometimes I get the odin complete write operation failed error, wich the only way that I've found to solve it is to reboot again the phone into download mode.
I know that the battery is working, I have another core 2 (same exact model) and battery is ok. At this moment I don't know what else to do. Please, help me to get this brick of a phone back to working conditions, I dont want my friend to buy a new phone just to use it to recive calls and charge it.
Some extra notes:
As i've read, sometimes this can be caused by the replacement of the digitizer/screen. This phone seems to have one or both of them replaced, since I can see glue residues on the corners of the glass, where it touches with the plastic frame.
If there is anything hardware related thing to try, I can try to open the phone. I have some experience doing so.
EDIT: As I continued reading through this forum, I found out that some people had luck with Odin3_v3.13.1_3B_PatcheD, so I decided to try it out and see. Still, nothing changed. As today, I can only use this phone to charge the battery (it dosent actually show the percentage, only the battery icon with a loading icon inside) and boot into download mode
Although, I have to say that after flashing the stock rom with that version of odin made the phone not that hard to start in download mode. I think that it could be something that got corrupted on the eMMC module and it has to repartition it all again...? Does anyone know how to do so?
Regards
Well, tried almost everithing I know. Downloaded rom again with binary nature, tried with odin version 3.12.7, 3.13.1_3b patched and 3.13.3, but nothing. Extracted the PIT file from the CSC file, did repartition, NAND wipe, and nothing changed. I have to say that its certaily easier to get the phone in download mode, but thats almost it. One thing to note, when i select the NAND wipe, it dosent seems to do anything. I mean, in odin Log screen some things appear related to NAND wiping and such, but its really fast and there are only 2 or 3 lines dedicated to that. Is that OK?
Anyway, please, any recoomendation or thing to try would be great, since this phone is now trash, it dosent matters if it starts to get worse, or even unusable (more than it is rn).
Regards
