Black screen and 0 activity - Samsung Galaxy A80 Questions & Answers

Hi everyone,
I am the owner of a Galaxy A80, it was working perfectly then today suddenly it turned off by itself and I'm not able to have it work again: recovery mod doesn't work, charging it doesn't do anything, no download mod working, it became a piece of metal and plastic with any sign of life.
What can be the problem according to you and how to fix this?
Thank you

Hello!
I would recomend to open up the backcover, unscrew the plastic cover and unplug the batteri, it happened me once and it worked perfectly!
EDIT: then ofc i screw back the plastic cover and reinstalled the backcover!
BE CAREFUL! u most likely crack the backcover if u are not careful!

same problem as so_ony i think
Light scratches on screen, put a screen protector and you shall not see those again and also save it from any further damage.

Hardware Question about Xperia Go and Water...

I just bought xperia go today, very excited the first thing I did was make sure the phone was perfectly sealed I put a glass of water ... I was surprised to see that many air bubbles came out and scare me.
When it out all works perfect ... but to remove the back cover, the blue part is very wet ...I just dry and ready.
My question is: is normal to get water to this part of the phone? between the rear cover?

[Q] Screen replacement - about the adhesive

I bought a screen assembly replacement (next time it will be better to buy it complete with the front housing), everything is fine but it seems that the edge of the screen arent stick that well (especially the buttom edge - where the back button etc).
I cleaned the original housing before attach the new screen, include in the edges and I've tight it before install the motherboard and etc...
Anyway right now I've putted insulating tape with pressure on the edges and all over the sceen (attached to the back cover of the device), playing a movie on highest brightness (to make the screen hot) and put it on case that pressure on the edges
What else can I do? it wasn't lift up (the buttom edge, each time its other edge) everytime but its annoying.
I guess next time (if not buying a housing assembly) I should put another adhesive on the edges of the glass, seems their adhesive is not enough...
or should it be like that at the first?
//edit - I've found a thread that describe the same problem:

You have three chices:
1) Try to repair the phone, again.
2) Ask in the thread you've linked to how to fix it.
3) Take the device to someone who can properly install the screen.

Well seems like its happened because there is no adhesive at the sides and at the buttom...
I'll try to stick some adhesive on these places without disassembly the screen, only under the glass sides/buttom...
What adhesive do I need? is this ok? http://www.ebay.com/itm/3M-Attachme...707231?pt=AU_Scrapbooking&hash=item5aefa6425f
to do it properly you will need to remove the screen and get a complete new double sided sticker for your screen, the foam in your link will not allow the screen to sit properly flat down

View Cover thinks it's closed although it's flipped all the way to the back

Hey guys,
I got myself a View Cover for my Note 3.
Now I've got a problem:
When completely opening the cover, so that the front view is on the back of my phone, the phone goes into the "cover is closed-mode", i got that square view and can go to camera and action-memos...
But i just wanted to use my phone normally,
Is it just me with that problem or has anyone the same problems?
phone is in "cover is closed-mode" when it's actually closed
phone is in normal mode when cover is opened
phone is in "cover is closed-mode" when it's flipped back completely
Thanks in advance!

I've got the same problem. I stopped using the s-view case because of it.
Some people say there were some defective batches where this was an issue (magnet too strong?), and others say they don't have the issue at all.
If you have the option, try exchanging it for a different one and see if you get better results.
I had the same thing happen as well. I let the company know and they gave me a new case. Hasn't happened since.
Are you guys talking about genuine S-View covers?
Because I get that sometimes on my cover, but it is a cheap chinese knock-off, so I don't mind it at all - it rarely happens anyway.
But I wouldn't accept that on a genuine Samsung cover.
I've tried another cover, too but the problem remained. I aswell am using some chinese knockoff, although it says samsung... But yeah, can someone tell me if the original view-cover got that problems?
Thanks for your replies!

Genuine Samsung s-view cover doesn't have this issue
I've got a genuine cover and I don't have this problem at all.
If its a knock off, good chance the magnet in the front of the case is too strong. I've noticed if I put a magnet up to the bottom left of the phone, this will trick it into thinking the cover is closed. Similarly if its done from the back of the phone, if the magnet is too strong it will trigger the same. not sure if theres something you can place in the back cover of the case to shield it?

First, thanks for your reply!
I will check if I can protect the back somehow.
But anyways, I am thinking of buying another view-cover because my phone won't recognize mine from time to time... Have to reattach it to get it back working.

The official Samsung flip cover doesn't work!

I changed it 2 times and it still the same bug: The case sometimes stopped to work, then sometimes works again !
I can't figure out if it's a software or hardware (both?) problem
Other people have the same problem:

Any idea?
Yup, my flip led case having the same problem.:crying:
Did you try the post-it tip as said in commentaries ? It worked for me!
Maarten van Herpt8 months ago
solved the problem: put a piece of paper in the cover, for example a post-itt, put the phone back in and it works! bizarre but true! maybe something to do with the glass backside that influences the magnetic field? happy that it works again!
Same problem.
