[Q] WIFI & sound problem

Hi, i did not find any related to my problem, that's why i am opening this thread.
I did a brick on my tf700 at last September and the cheapest solution it was to buy a new board on ebay.
i did the replacement that it was easier than i supposed and it started to work like new, like the first time the system ever boot.
After some days i did again unlock and install cromix and during several weeks it was perfect until yesterday when I detected that it was not good WiFi.
It is like half of intensity compared with htc one. Just works up to 8m from router.
I open it again to verify contacts, board. Everything is normal.
Do anyone know about antenna problem on tf700 (on my last prime it was a lot)? or hardware problem that in a moment reduced the intensity, if it was no WiFi at all i understood as a hardware problem, but half is strange.
Another thing is sound. When i started tf700 no sound, just on phones. After some hours (from night to morning) tablet working, sound appear.... i don't understand.
I tried different firmwares, now i am on cmb 4.3, and it is the same.
Any help?

If you use a different rom and you still have the same problems, then you may have a defect motherboard..
You can try to install a stock rom to verify the issues that you have. If you still have the problems, then you can confirm that you have a bad board.. Good luck..:fingers-crossed:

I already ordered another board from other guy.
My doubt is if the problem is at the ROM level, or kernel level.
Is not possible to take a log to see what Android reports at startup for sound and WiFi?

Did you do a clean installation of your rom? If you flashed different kernels, you may have messed up the wifi modules.
Or it is another bug that has been discussed lately in the CROMi-X forum. If you turn wifi off and then on again: Does that change anything?
Some people had bad download speed when waking from sleep, whereas it was fine on a fresh boot or after toggling WiFi on/off.
If that is your problem, try turning off WiFi Optimization in the WiFi settings.

[Q] Intermittent call volume drop

I've been digging as much as I can on this issue, and so far I haven't been able to find any official acknowledgement or diagnosis of this issue. Please forgive me if this has been discussed before, but I simply cannot find the thread.
So far, I have had 2 Nexus 5's. Both of them had the exact same issue. When I am on a call, occasionally the volume from the other side will drop to a level where I cannot hear it. This happens most often when I am listening through the earpiece, thought it has happened while using speakerphone and multiple bluetooth headsets (plus my car). There doesn't seem to be a specific thing that triggers the issue, the area or type of phone I am calling doesn't seem to matter.
The phone is stock, I've never messed with the OS and the only apps I've downloaded were basic free ones, too many to list but if an app could be causing it I can post a list.
So far, I've tried the following to resolve the issue.
1. Factory reset both phones
2. Change sim card
3. Contacted my wireless provider (AT&T)
4. Contacted LG
5. Contacted google
Changing phones didn't help, Factory reset seemed to fix the problem for a bit but it came back. Changing sim did nothing. AT&T told me that because the device was third party, it wouldn't work properly. (I don't believe that for a second) LG just wanted me to ship the phone to them. (Not an option as they will take 2 weeks to get it back to me) And google just gave me some basic troubleshooting tips that I had already tried.
I cannot RMA the phone, i bought it used off of Swappa. I do not want to pay LG for a repair as this is a software issue and it should be solvable on my own. (though I will send the phone to them if it comes to that)
Has anyone had this issue, or at least heard about it? The only possible explanation I've found is that there's a problem with the noise cancellation software, but no one seems to have any solutions other than send it to LG, which really isn't an option for me at this point.
Thanks a crap load in advance to anyone who can shed any light onto this.

Bump for help please.

We are in the same boat

I'm being searching a lot to find a solution to this problem, but no luck.
I am using a Nexus 5 from the past 15 days and have the same problem of low to no volume from the speaker (voice of the other party). I initially though that it happens when I am outdoors, but no, it happens indoors too; and this does not happen always, sometimes it is loud and clear sometimes it is not. So I suspect that this has got something to do with the software rather than the software.
Even I don't have an option to send it back to LG cause I bought this in a different country.
My phone is Stock OS, updated to 4.4.4, rooted has Xposed Framework on it.
I also modified the build.prop and set the persist.audio.fluence.voicecall from true to false, but even this did not help.
Please, please, please, if anyone has found a solution to his please let us know.

If you press the back of the phone slightly, does it lower the sound? when i do not apply pressure to any back part of the phone, the sound is clear. with even slight pressure the sound dims on the other side. just noticed this today after trying to troubleshoot the problem. really bad design

So far I haven't been able to try that. For some reason the phone has started behaving, though there are a few issues here and there. I'll try this out next time it happens and report back.

Galaxy S6 Bluetooth stuttering issues

I want to take a minute and share a bluetooth issue I've had with my Galaxy S6. Maybe others have observed the same thing, and while I'm not specifically looking for a solution, suggestions are welcome. The S6 is about 3 months old, Andriod 5.0.2, unrooted, and other than Apex launcher pretty vanilla.
For the record, with the exception of the issue I'm about to describe, this phone has been phenomenal.
I use the phone in my car over bluetooth to and from work every day. For the first two months this worked great, no problems at all with podcast addict or poweramp. Then, I noticed the audio would dip momentarily. As if someone turned the volume down and back up. The bluetooth connection never gets lost, just the audio dip. Then, eventually the problem became perpetual. I will describe the symptom the best I can, as if the volume were being turned up and down. This wasn't the case, more like the bluetooth stream was somehow going away and coming back.
I tried all the obvious things, like re-pair the phone to the car, clear the bluetooth cache, Volume Up + Home + Power button and then "wipe cache partition". As a last resort I did a factory reset. This last step actually solved the issue, for a while. This was a few days ago, but this morning I noticed the same periodic blips in the sound, so I suspect over time the same problem will once again return.
<rant>
I was in touch with Samsungs customer support, who is supposed to "values you as a customer and want to insure that we have provided you with the answer you were looking for". Unfortunately, the blunt truth was they ended up being useless with an offer to allow me to send my 2 month old phone to them and wait for an undisclosed time, for what might end up being a refurbed replacement.
</rant>
Since I don't see mention of this in the forums, maybe it's not a wide spread problem. Maybe a compatibility problem between these two specific chipsets? Whatever the issue, hopefully some future update comes out that fixes things. Defaulting the phone every few months would be a considerable drag.

Ideas on Diagnosing Bluetooth?

I am having an incredibly frustrating issue and I am hoping someone may have some insight?
I have a Sennheiser Presence bluetooth headset. The headset worked very well for many months. Then, at a certain point, it just stopped being recognized or discoverable by my phone (Galaxy S7). I tried updating firmware, resetting the phone, wiping cache on phone, rebooting in safe mode, etc. Nothing worked.
The company sent me a replacement unit which started out working, and then after several weeks also stopped working. I have now gone through this 3 different times and each time its the same - works for several weeks then suddenly seems to stop. On the one hand, maybe its a hardware problem with the headset. On the other hand, I have read reviews on Amazon, googled, etc. and havent seen anyone else reporting this kind pf problem so I feel like maybe there is something going on specific to my device.
I cant figure out what else to check or do and I wonder if anyone has this experience or suggestions/ideas?

By the way, my other headset (Plantronics) doesnt have the problem - it is discoverable and can pair. It is just the Sennheiser.

Recent problems with wifi, bluetooth, over heating

right now I have been using G4 for a long time.
And many problems start to appear on my phone.
I have got Bluetooth lagging, so sometimes disconnected with my earbud.
I have got no internet on 5G wifi, but 2.4G wifi works fine.
I have overheating problem and battery draining problem.
I want to know what I can do to fix or reduce the problem. Please don't tell me to buy a new one. I know it can be a solution.
Another problem is it only get Android 6.0 and I have att version but I am on Tmobile network.
I also want to know if any 3rd party Rom provides have a 7.0 or 8.0 for that?
Any suggestion can help.
If no way to fix or improve, I will look for a new one.

If you google LG g4 boot loops it’s all a common issue. There are fixes like baking it in the oven, taking it apart and redoing to heat sink or whatever. But only actual fix is replace the phone. The G4 is common for hardware failure. Just make sure you backup everything as it wouldn’t be a surprise when it bootloops, usually there’s no bad signs before bootloop but can still happen especially since your having hardware problems.
You’ll need an AT&T sim to update the device. Sorry can’t answer on custom Roms though.
