S3 Sudden Signal Loss - Galaxy S III Q&A, Help & Troubleshooting

Hello peeps,
had my S3 for 7 months and it's starting to play up, I dropped it in the car once on to the carpet, and it went for a quick dip in the bathroom, however once all dried out and what not it was fine.
However i've a recent problem that started about 3 weeks ago.
I was browsing imgur and the screen flickered like if you moved a TV aerial (lines horizontal) and it switched off. Then I was stuck in a boot loop regardless of flashing any ROM until I used ODIN to restore to a stock ROM, everything seemed ok so I went back to Omega ROM. The on going problem is in phone calls I'll go from 5 bars of H signal to a circle with a line through it. the phone says no network coverage, once it gets back into gear sometimes 5 seconds other times 5 minutes the signal comes up 5 bars try to make a call, 'not registered on network' give it a minute and it works again only to make another call and it happen again, sometimes it's a 90 min call other times it's a minute.
I've contacted my provider for a new SIM as once it said 'No SIM inserted' however I think it's a bit more than a SIM issue any advice welcome
I did search for the issue and people mentioned IMEI numbers being incorrect or missing, mine IS CORRECT and present.
Any help very welcome.
Thanks
Luke.

[Q] After being send to service center, S2 is worse (signal and speaker problems)

2 weeks ago, I took my galaxy S2 back to the shop to get it fixed under warranty.
The USB port was broken, as with so many S2's. I got it back after 2 weeks and the port was replaced for free.
But now the speaker doesn't work anymore! So I get no notifications when called or texted or alarm or can't play music, the phone thinks it plays the noise, but it doesn't. Also in the *#0*# menu, when speaker is pressed, nothing happens, no sound at all.
The internal speaker to make a call does work, so you can hear the recipient of the call.
But if that wasn't enough, I also get bad reception where before I would always have great reception. Now it just goes away and the phone almost never gets more than 2 bars, while my friends with the same carrier get full reception. I put my simcard in my other phone and there I have good reception, so it's not the sim card that is the problem. Also the wifi reception is worse. How is this even possible? My phone is worse than before. Before I got 3 bar Wifi connection in my room and 1 bar in the bathroom and now 1 or sometimes 2 bars in my room and no reception in the bathroom.
I reset the phone and everything, also searched the forums and found nothing.
I'm not very eager to send it in again, since they make them worse than before.
Anyone got a solution?

How old is the phone and how long has this been going on? Any water damage, drops, anything like that?

Null IMEI and Tons of Problems

Hey
This is my first post and I don't know if this is the right thread or not so I'll just cut to the chase
So I have Sony XPERIA C5 Ultra E5553 for half a year now.
On July 6th 2017, My phone just shutdowns and really hard to boot. I noticed that maybe my battery is getting disconnected in some sort of ways. (Because while charging the LED light is RED while it's even fullcharged)
So on the 7th of July I send it to the warranty Service Repair SONY Philippines.
For almost 3 months of waiting I got my device back last September 28 2017 (talk about really slow repair progress)
I noticed that my phone is Updated to the latest Android Version Marshmallow.
Upon inserting my sim card I noticed that it kept on showing the sim card logo on top even though I already restarted my device. I leave it that, arriving back at home I noticed that my signal bar is empty. Before giving my phone to Service Center my phone can generate 3 signal bars in GSM mode which I always use for battery purposes. So I restarted my device with same result the SimCard logo is back on top.
Pissed, I restarted my phone for 4 times noticing that sometimes the Sim Card logo is replaced with empty signal bars (which I said Supposedly have 3 bars).
Upon my curiosity, i tried to type the *#06# and upon my discovery my IMEI number is missing and replaced with NULL.
I tried to contact SONY for why did that happened but sadly no response.
After a few hours I noticed that my phone will pick up signal full bars on GSM, 3G and LTE and checking my *#06# my IMEI is now back. (On some location which have REALLY high signal)
Even right now, I tried to restart my phone again always the same having no IMEI for almost 1 hour then after and hour the Signal will appear strong. Moving in different places where signals are a bit low it goes blank and will never receive anymore signals even I moved back to high signal areas.
I'm having 3 theories,
A. Sony sabotage the repairs because I kept messaging them to speed up the process (because it took them 3 months to replace a battery where I can do in few hours). PS. They even broke our sony sound system when we send it for repairs last 4 years ago.
B. The Marshmallow update because sometimes the screen stutters occasionally. And because, I have an old phone that I updated to different ROMs that sometime FIRMWARE affects Hardware functions
C. My phone is broken and I need a new one which I can't afford because I'm not even done paying the credit on my Xperia.
For anyone will kidnly help please help.
Because if not, a few days from now SONY will soon receive a tons of message coming from me using my hundreds of Accounts just to spam them to replace my device.
Good day and I really hope I posted this on the right thread.Sorry for the Long story really need to remove this from my chest

Replacement logic board for Be2026

Hey guys,
Long and short of my issue:
Dropped phone in 6 inches/ 15cm of water. It stayed on, no apparent issue. Dried it off, took it off for 24hrs.
Two days later, while using it, sim card and wifi went on the fritz. Wifi and sim will detect then drop off...sim is every 15 seconds. Sim is just fine in another phone. Without sim in the phone, wifi sometimes connects and stays stable.
Factory reset the phone, everything else is just fine, got wifi long enough to restore everything and update.
I am in the caribbean so a no go with sending phone to oneplus for repairs.
Any suggestions on where to purchase a logic board (used or new) doesnt really matter from where as long as its working?
Saw a metro be2025 on ebay, will this work with my phone? Will I have issues trying to unlock it (read some horror stories about it)? Read a couple posts about the minute differences between the models so looking to try it out.
Thanks in advance for any advice!!!

No more cell signal. (Bell canada)

Heya so it all started about a month ago when my phone would suddenly loose connection to cell tower, the only way to fix it was to reboot the phone, but now since a week or so, i cannot get anymore signal no matter what i do (signal icon next to battery percentage stays at 0 bar and a little x on top left of it), rebooting does not help and even doing a factory reset did nothing, i went to local bell store, one of the seller tried my sim card into his personal phone and it worked. They suggested that i go to a repair store. I did not drop my phone since forever, although it did heat up quite a lot about 3 months ago (charging under a pillow while running a video, it was hot to touch in the morning).
I was wondering if its a common issue or if anyone got an idea whats going on, im thinking itt might be a hardware issue with the transreceiver or whatever its called.
Any help would be appreciated. Thanks!
Ok what the hell, it just came back after over a week, rebooted a dozen time but this time it fixed it, for now.
Although with the new work contract i work in an area with very high magnetic field at specific spot (400000 or 600000 amp of power going tru the building), like some hand tool would would hold straight up in the palm of my hand and even my versaflo respirator would go crazy, passed a dozen time in such field with my phone in pocket, maybe that helped?
