i went to the service centre after a touch problem showed up on my phone and they told a software update is available and my phone was loaded with Cyanogen OS 12.0. But since it did not have any rooting capabilities, i went ahead and looked up some tutorials but could not find one and therefore ended up using king root. But now after some time i've realised that my phone has lost its signal strength, first sim (being of jio) almost never receives signal and though my second sim (airtel) shows signal strength, the person on the other side is not able to hear my voice(only some cracks and disturbance). The mic is working fine as i tested it on sound recorder.
So, i want to know is it a software problem that can be solved at home or i'll have to go to service center(which i would like to avoid as it's far away from my home)

Nevermind: after another hour of the phone sitting on my desk, it started working again. Problem must be with T-Mobile's network.
I've got an HTC Sensation 4G running the latest stable T-Mobile version of Android Revolution HD (1.2.2). I had been running the ROM (Open Sensation 2) that the person I bought it from put on it, but installed ARHD a month ago and it's been working great ever since.
I went to make a call today and found that it dropped as soon as I dialed. This happened three times and then I noticed I had no bars in the signal and the data connection said "2G". I called my cell from another phone and it went straight to voicemail. I took the phone to the T-Mobile store but couldn't get a signal there and the guy couldn't figure out the problem (eventually he said they don't support custom ROMs).
A few other things I have noticed. I am able to get a very strong WiFi connection (and use WiFi calling as well as browse the Web). I get "four bars" of signal and the 4G icon when my phone boots up, but as soon as I unlock it, they both go away. I made a call on Friday evening and the phone has basically sat unused on my desk between then and now. I also cleaned the antenna contacts with an eraser and a cotton swab, but it had no effect. "Settings -> About -> Network" shows the signal at 0 dBm / 99 asu.
Any ideas as to the problem, solution, or things that might help me troubleshoot?

I took a nexus 5, 6 months back, i had updated it to 4.4.4. Since yesterday it ws behaving wierdly. My network would just drop and then upon searching for networks under mobile networks, i was able to reconnect bt suddenly it jst stopped working. i wasnt able to connect to any cellular network on any sim card whereas the same sim card was working on other devices. even on searching for mobile networks i couldnt find anything. i tried every possible thing, i switched to android L, and even downgraded my phone to 4.4.2 bt absolutely nothing worked (i knw that means unlocking my bootloader and i have lost warranty but i had to try something). please help me out, this is getting toooo annoying (P.S i dropped my phone once, got a very minor bump, is there by any chance a hardware issue due to that?) it is connecting to wifi network and bluetooth perfectly
If you've flashed a clean stock image, then unfortunately it's likely hardware. Antenna may have been damaged when it was dropped.
Or its a carrier issue. Or Sim. Did you try a friends Sim that's the same size?
I've been having fun same problem got the past week or so. I'm on T-Mobile and I have had no service, or service dropping to "H." Mostly it's just no service, then "low" service.
My device is lately having troubles at receiving mobile signal. It often loses it completely displaying the "no service" error.
Usually turning the airplane mode on and off works, and the device starts receiving signal again, but that's just temporary.
It generally shows no correspondence between the bars of the icon and the actual coverage and it might go from 4 bars to no service instantaneously.
The device is rooted, has the drm fix, SuperSU and busybox, but when this problem first appeared it just had the BL unlocked. I have the .224 stock rom, installed via FlashTool.
I controlled whether it was a SIM card problem, and it seems not; it first appeared when I was staying in a poor coverage area, so I thought that might have been the cause, but it's not, as I havr the same trouble (less often) even where I live. I have the general feeling that the device has become less capable of receiving signal, and that as soon as it is somewhat scarce, the phone completely loses it.
The idea I have is that my current firmware has troubles with my local network; I live in Rome, and my SIM is 3 ITA, therefore I chose the "customized IT" firmware among the 3 FlashTool displayed, which (from their names) seemed to be carrier branded firmwares.
Sorry for the long post, I've written everything I've thought might be useful.
Sucks I have the same problem, any solution?

You can try to install newest v253 generic firmware via flashtool.I dont have to to install specific Carrier Rom,that is not so important.
Install newest firmware and see what would happend.
Sent from my D6503
Metal Bumper cases also are known to interfere with Signal reception, but as suggested try flashing a clean firmware ( preferrably Global release ) and see if the issue persists.
I get pretty bad reception most of the time and then pretty good reception where everyone else has none. My phone is very confusing!!
on the marshmallow is a very bad signal I am currently lollipop 32.0.A.6.152 is a little better but there is no comparison with my old Z1 signal great
nougat may be better for signal strength.
why see about that.
google translator sorry
So I went to Sony to get my battery replaced. Sony wanted to replace my screen and motherboard so I decide not to go forward with it. Sony literally returned my phone with my display out and headphone jack issues. I went back and they "fixed" my display but with even more issues. But that all issues aside ever since I got my device back I am having issues with connectivity on my phone. Their service center claims they need to change the board to solve issues which didn't exist before I submitted my phone and they want me to pay for it.
Here's what's happening if I'm on LTE it will sometimes work in bursts but otherwise won't work at all. I have the LTE sign though. Data works more or less fine on HSPA+ if I force WCDMA in settings but sometimes the phone looses signal completely. I've tried replacing my sim, using my secondary sim (Jio, which being a 4G only network is completely unusable on this phone). I've tried flashing my phone with latest india ftf but that didn't change a thing. My Bluetooth range has also shortened significantly.
I purchased a used US version Rog Phone 5 recently through an online seller. When receiving the phone, I gave it a good once over and powered it on and tested wifi and such and everything seemed to be in good working order. I then rooted the phone and set most of stuff up. After inserting my sim card, I noticed the cell reception was not that great. I suffered through for a couple of days but was missing calls and texts like crazy. I was constantly dropping reception entirely in areas where I have very good signal with other phones. The phone is essentially useless now. I tried several factory resets, flashed back to the non-rooted boot image, and then flashed to an older firmware with no improvements to signal. I can't imagine the reception issue is in any way related to the rooting process, but I'm throwing this out there just in case anyone has seen anything similar in the past.
A few things to note:
I am on AT&T
The APN is definitively configured correctly
I could have returned the phone to the online seller for a refund prior to unlocking the bootloader, but did not insert a sim before rooting, so I have no idea whether the issue was present from purchase or not. Lesson learned, I suppose... do a more thoroughly inspection before doing anything that will void a warranty or refund agreement.
I have tried the same sim in two other phones with no issues.
Everything else about the phone seems to work perfectly, only poor reception.
I had the phone up to approximately 30 miles from my house with no change, so it isn't limited to a specific tower.
Does anyone have any ideas? If I don't come up with anything I will be posting it on ebay as "not working - for parts only" so I will try about anything at this point.
Sim recognition issue
Owned the phone for about a month now. Phone was working perfectly fine for the majority of this time. I use 2 different sims and they were both working smoothly until recently. A few days ago, I woke up and the phone wouldn't recognize the Sim...

sim card problem
just all of sudden it became invalid sim try multiple time reset or clear data cache sim toolkit original sim to other phone is working other sim to original phone is working other sim to other phone is working anyone face the same problem...

Sounds like they pawned the issue off on you, but it should still be under warranty to have it repaired. When you contact Asus, don't mention unlocking the bootloader. Stick to the hardware concerns.
I have looked over both of those threads, but it seems to be a different issue. My sim is recognized fine, its just the signal strength that appears to be extremely low. Even when the phone has no service at all, it still recognizes the AT&T sim is present.

Yes, it is not the same issue, but it appears to be a similar issue. The important detail being that both required a motherboard replacement.
