The back of my phone is cracked and apparently fell off awhile ago but wasnt an issue because I have a phone case. However, now I am experiencing issues and fear its an antenna issue.

How do I know what the cause is and how do I go about fixing it? I can fix it myself probably, I am not afraid of a DIY. but my phone is unlocked and I do not have insurance on it so my provider wont fix it. I just want to know what the issue is so I can try to fix it

I recently bought a replacement screen for my Samsung Galaxy S20+ from iFixit, but after installing it, I noticed it already has burn-in marks. This seems unusual for a brand-new screen.

Has anyone experienced this before?

When the battery reaches zero, the phone shows the charging symbol when I connect it to the cable, but the rotating circle doesn’t appear, and it won’t start charging. I’ve tried keeping it plugged in for an hour, but it still won’t charge. As a workaround, I tried charging the phone wirelessly. Once it reaches 1% charge and the green circle starts rotating on the screen, I can connect it to the cable, and it will begin charging normally.

I’ve also noticed that OTG does not detect any USB drives.

I tried replacing the charging connector along with the board, but this hasn’t resolved the issue. Could you help identify the exact problem?

So i tried the original battery to confirm the phone was working. and phone boots up without any issues and while charging it pulls 18-20watts easily.

I contacted ifixit support and they arranged another replacement battery but this battery also does the same thing. Not charging and phone doesnt turns on. Phone still works with the original battery.

So are there any hidden steps that i got to do during battery replacement process or do i just have bad luck and got 2 dead batteries?

My refurbished Samsung S20+ keeps restarting several times in the day. Have never been able to use it fully for months. Sometimes it happens immediately or a few minutes into using my phone. Many times it will stay stuck in a continuous reboot loop for minutes and the IU One shows... I've tried everything. Help!

Thanks!

I just replaced my S20+ 5G with a 3rd party screen + chassis and ran into an issue. Everything installed perfectly and powers on as expected, but the screen never turns on - I can even feel the vibrations from inputting my lock screen code, but I can't see a thing.

I was comparing my two displays and I noticed that the resistors(?) by the display cable on the bottom of the phone were different. The broken but functioning one has a 4x5 grid, whereas the new one has less resistors and are in a different pattern. I currently have everything reinstalled in the old case and am waiting for a new replacement to come in.

I was wondering if anyone knows if this change in resistors could cause the LCD to not turn on? Or since I am getting tactile feedback, it might just be the display flex cable that's messed up? Not trying to spend too much on the phone, so looking for advice before spending the extra $100 for a genuine Samsung screen. TIA!

I powered it off and plugged it in overnight and it was back to normal and fine all day yesterday. Plugged it in last night before bed - zero issues. Now this morning the screen is black and won't turn on at all. The touch seems to work though, I can input my swipe code and it'll seemingly unlock and show up on my PC.

I've done the volume down and power button restart thing a few times with no success. I've tried using Windows Phone Link and Samsung DEX to get into my phone but I can't see the phone screen to complete the setup.

Any ideas? Screen just dead but phone OK? It did get dropped in water about 24 hours before the screen issue started but other than the "moisture in charging port" message it was perfectly fine.

1. disconnecting and connecting OG charging port fix the moisture problems but randomly happen again in between 1 to 3 week
2. I get no network if i boot with replacement charging port.
3. If i boot up with OG charging port, then change it to replacement charging port. everything works Till i restart the phone

why is this happening? is samsung blocking third party parts?

forgot to say when i meant no network, it mean a a circle with a line cross it

but yeah, i meant the whole USB-C Charging Port. my phone is the Taiwan model(i am in UK currently), the G9860, i made sure the replacement part is for the G9860(its printed on the board).

If its incompatible parts that is causing the network problem, it should just not work at all, they fact the changing part works mean its not a hardware problem right? i actually went to a third party repair shop with the same result.

oh, i just noticed the above pic is the exactly same as my replacement part(all the model number matches)

but my OG part is slightly different compare to the above pic, highlighted the red circle from picture of my OG part
