black screen after dropping it please help! - Samsung Galaxy A21s Questions & Answers

Just dropped my phone flat down on a hard surface.
Only micro cracks on the screen, but it remains black. Buttons are still working,.
I noticed when I light turn it off and on that there is a tiny flash of light happening for a mirco second, and was wondering if the shock may have slightly disconnected the screen.
Do you reckon that would be possible and if so, should i just open it to verify everything is well plugged / connected inside? Won't hold you responsible if I end up breaking it

It may be a loose connector.
You already know the display needs replaced.
Any high G impact can damage the mobo even cause internal damage to chipsets.
You'll need to go one step at a time.
If you start replacing components use/observe full ESD protocols to avoid damaging discreet components assemblies including the mobo.
When out of circuit the assemblies are more susceptible to static discharge than when in circuit fully assembled.
In the future use a good case with raised screen guards like the Zizo Bolt to prevent this.

can it work to only change the screen

If that's all that's damaged. Watch some tear down vids first. Have all the tools you'll need and some anhydrous isopropyl alcohol to help loosen the adhesive seal strips on the rear cover and battery.

In need of a keypad+wheel

I have been checking some online-shops (inc. ebay) in the search of the keypad(plastic thingie, without circuits) with a wheel but with no luck - they are not sold separately from housing, nor many housings are sold without them.
Can anyone give me a clue if I can find that piece somewhere?
It seems there is a thin metalic layer. This one is very fragile: on my phone, this layer begins to peel off. Does anyone know how to change it?

that same **** happens to me, but no that serious, only the little "line" that its in the red and green icons. I guess that your using your fingernails, right?
Nope. But when cleaning my screen, I put a little bit of water on it, then rub it with a tissue. I think the tissue gets caught on the small holes and tear off the metallic layer... One of my colleague has the same problem.
Once it has begun, you cannot stop the layer unsticking.
Uh! need!!
Yes I me too..
please help... broken idem.-
Mine is even worse not even the metal layer has been scratched off but the keypad is also cracked in the middle and the scroll-wheel does not work
This keypad is really a crap. And the phone surface is not guaranteed by HTC (of course)!
I will receive an HD 2 in a few days. My operator could rebuy my Polaris for 18 € (for recycling it)
to wagner51
dude if you're gonna sell it that cheap, let me know. i'll give you an alright price for it with postage etc
same problem
I am facing the same problem: the metallic-coated front panel is scratchy, and just last week it was broken from the upper middle section. If anyone could give advice on how to fix/replace it, it would be most appreciated.

Somehow the battery of my mini pro found its way into the washing machine and made a complete wash cycle in there
Is it save to put it in my phone to check if its still working or can it damage my phone?

first thing is make sure your battery have really dry yet
then if you dare, try it to your phone
as far as i know, some electronic things is safe to be washed
but before use it, make sure it really have dry yet (like motherboard computer, its safe if you washed it, of course it have been plugged out from the case then use it when it dry)
sorry for my bad english
Best thing to do is get a new battery.
I for one wouldn't risk putting a 20 euro battery in my 250 euro phone.
Admit defeat and get a new battery, or you might have to suffer the consequences of screwing up a phone. If a single droplet is between the wrapping, it will turn into "steam" when it gets hot, and your phone might suffer damage due to the water that will eventually build up.
After over 3 weeks of drying i just risked it and its working fine. The phone even report the battery as "good"
use rice to dry the phone or battery.

[Q] Spot on the Gorilla Glass

I have problem.
Watch this:

And when I touch finger...
I can clean this by cloth by when I touch finger is very big SPOT!
WTF?
Warranty get this?
Sry for my Englis...
Lol you mean that big finger print that you also can clean with a cloth?
Yes it is a warranty case!
No, no, no.
When I clean cloth I have cleaned display, but when I move finger on all lenght few times I see this spot.
If after cleaning with cloth your screen is clean
If after booting your screen is clean of any problems
Perhaps you need to clean the screen that might be greasy.
But if you see spots when booted, you got burn in.
Maybe this photos can you explain this "damage".
and
I can clean this by cloth and it's good, but when I move finger I can see spot. Big spot only in this area.
can't see anything, sorry
Is it under the screen? Is it water damage? If you know the circumstances that led to it you can find whether its covered by Samsung. Or better, just call Samsung.
Sent from my next
It's on Gorilla Glass, phone is works, but spot is only when I move finger.
This spot works like magnes who catch metal, this catch something oil...
Maybe something to do with the screen. Get it checked by Samsung .
Finally Samsung give me new sccreen, now it's ok

[Q] My screen lost it's resolution?

Hello,
First of thanks for even looking at my problem also excuse me for my bad english or when I missed a similiar thread with the same problem
Last friday I was keeping my galaxy s3 between my body and my sports pants/underwear. When I took it away there was a tiny little bit of moisture on the screen (sweat I guess). I wiped it of and continued using my phone. After a while the screen started to go pink and flikkering white in different brightness levels. I quickly turned my phone off and took the battery out. I left my phone on the boiler in a bowl of rice overnight (+/- 15 hours). When I turned the phone on again it worked fine but only my screen has a very low resolution now. The rest of the phones functions are working just fine!
Does anyone know how this problem whas caused, if it could be fixed by me and if it could be under warranty (Standard dutch warranty of 2 years, my water/liquid indicators in the headphone jack and behind the battery are still white and white with blue x's respectively).
This is how my screen looks now:

(It's less visible on camera in my opinion, hope you can at least see a difference to understand what I mean with 'lost resolution'.
More high res image can be found here:

Thanks in advance!
I'd take it into the dealer and show them - it should be fixed under warranty I think. I would not tell them about the moisture and to be honest I don't think that is the problem. I've had water splashed on my phone with no effects. Also, the screen is fused to the glass (which is why cracks are so expensive to fix - you're buying a new screen) so the moisture would somehow have to get inside the casing to affect things. It clearly hasn't done that if the indicators are not showing water effects.

Maybe its me but it seems the magnets don't agree with phone at all , plays havoc with screen unlocks when attached to it and all sorts.
Would the magnetic in the mount interfere/degrade the phone's battery?
I have a similar mount. If the magnet gets too close to the power/volume buttons it puts the screen to sleep. There must be a sensor there for a smart cover.
Not sure about effect on battery. I'm considering switching away from the magnetic holders, simply because I hate having to hide a piece of metal under the case, and thusly can't use my clear Ringke Fusion case.

The magnet sensor of the N6 is behind the M-logo. A magnet at that location (front or back) swithes off the screen.
My solution is to use silicon case and a metal plate fixed at this case with superglue. Positioned below the M-logo. About 1 cm.
Check it by keeping the magnet below the M-logo untill the screen stays on.
Because the back of the N6 is not flat, the metal plate must be rather large and firmly fixed (pressure a few hours).
This way of mounting does not affect the battery life, but when using wireless charging, the case with the metal must be removed.
That's why I use a silicon case. Easy to remove.
