Phone freezing and restarting when answering and making calls - LG V30 Questions & Answers

Hello,
I started facing issue with my phone freezing and restarting, sometimes when I try to answer a call or when I start dialing. When I answer a call, the timer starts, but I can't hear anything - phone becomes unresponsive and I can't do anything. After that it just restarts. When I dial, my phone freezes, but the other side still receives the phone call - the problem is that I can't hear anything and after couple of seconds the phone restarts again. Anyone else faced this issue previously? Can someone share any ideas what can be done. If I download third party app from the play store - will I be able to set it as default one for receiving calls?

Thanks

Did you ever root the device and mod it? If not, I suggest a factory reset.

I think the issue was caused by a black pie theme that I bought from google play store. I'm using the default one for couple of days and I don't have any freezes. This is the theme in question, I suggest you guys avoid it, at least for me it caused this issue. https://play.google.com/store/apps/details?id=giap.lge.pblack

[Q] Dialer issues

Has anyone encountered problems with the dialer?
I can punch in a phone # and press the green button to dial, but it doesn't dial immediately. There seems to be a lag sometimes of up to 30-60 seconds.
Also, sometimes I cannot hang up a call. I press the disconnect button and it just doesn't do anything.
phone app/dialer issue
hello,
i think that the same happened to me. the problem that I am having concerns the phone app on my razr. very, very often when I try dialing somebody, after hitting the the dial button, the screen where is shown a larger photo of the person that I am calling appears then it flashes and disappears (saying <call time 00:00>, something like when the call is terminated) then it reappears by itself after 2 or 3 seconds and the call continues smoothly. this is a very annoying problem, not being able to have control of my calls.
i don`n know what could have started this problem because everything was working fine, and still is apart from this issue. i`m not a skillful android user but i managed to root my phone (making all the necessary backups), then using some specific apps for rooted phones (like titanium, motomizer etc.) and every thing was OK. Lately i`ve installed a navigation program for android to my phone (iGO) but i`m not sure if by doing this, the problem appeared.
to solve this, i`ve tried everything: uninstalling all the suspected apps, factory reset, rolling back my system to a previous backup, updating my system version from 651.73.30.XXXXX.en.EU to 651.167.19.XXXXX.en.EU, cleaning the cache/dalvik cache. the problem still persists...
if you guys have any idea what could have caused this please guide me through a solution.
thanks!

[Q] Blocked incoming call screen

Straight to the problem: sometimes (and in a very unpredictable manner), when i have an incoming call, plenty of problems show their ugly face. First of all, i sometimes can't accept, or decline an incoming call, because the screen isn't responding to input. Sometimes i can go around this by pressing the on/off button twice, and that would enable the screen. But, sometimes even that doesn't work. The phone just keeps ringing until the caller eventually gives up. When that happens, the phone continues to function normally.
Another problem is constant vibrations i noticed in several occasions. Instead of vibrating in "pulses" or "waves", the phone just keeps vibrating constantly, which can be very annoying in combination with the problem mentioned in the first paragraph.
At first i though it's a bug in my ROM (CM9 port for legend), but have heard people experiencing the problem on other stock devices (Galaxy SII on stock ICS, for example). So it is not that rare, but to this day i haven't been able to find a solution.
Did anyone manage to solve this problem, or find any information as to how this can be avoided?

I have the same problem with my phone. Any solution for this problem thx
Reflash, reflash, and if it happens again - reflash. The screen lock/unlock workaround was working about 90% of the time. I gave the phone to my father (clean new flash) and he didn't experience any issues with the rom so far.

[Q] [P][JB] Problem with phone app

Hey guys.
I recently upgraded to JB. I have an Xperia P.
Most of the things work, but there is a BIG issue with the phone app.
It lags and crashes to the point that I literally struggle to receive and make any call. It is by far the worst bug you can get in a phone. Coz then it ceases to be a PHONE.
Anyone else got this issue? Maybe there is a way to fix it? I have tried to repair the phone via PC companion, but nothing.
Hi
I also experienced this problem, while receiving calls it's sometimes impossible to answer (slider locks on the right side of the screen and application freezes) and make calls - short lag appears after touching the contact, then the screen blinks, then it calls or freezes. It's becoming more and more annoying. I've tried wiping data and cache of Phone application, neither helped.
That being said, I'm currently on a Jellybean 6.2.A.0.400 build, unbranded (changed from branded build, my contract provider is still keeping the OTA). I'm always in battery stamina mode and I'm using Apex launcher instead of stock.
Maybe something is interfering with the app, I don't know. Other thread about ICS being laggy suggested limiting background process limit - I didn't do it just yet, I need to check if any of background apps are not responding (turned Show all ANRs on, I wonder what will happen).
I hope somebody will find an answer to this problem.
Cheers.
I used to roll with nova launcher too, and i have the impression that when i changed back to stock, things were better.
But still not good enough. There are times that when there is an incoming call, the phone just vibrates, without any ringing.
It seems that the issue was solved in A.1.100 update, as it does not occur anymore. However, sometimes there's some trouble reaching me on the mobile, as if I had no coverage, the calls go to voicemail. Anyone has a solution?

Calls Getting Delayed

Hi, i am experiencing an annoying issue while making calls.
it occurs when, i start to make a call but cancel it before it gets connected. and try to make a different call afterwards.. After i try to place the second call; it gets delayed for like 10 seconds. in that 10 second time period, the phone runs other programs normally . and suddenly it starts calling..
This gets very annoying . I reseted and reinstalled the system via Companion tool its still the same..
Anyone experiencing this issue and any ideas how to fix?
* I was using Truecaller and other calling related programs. Uninstalled and still the same.
* Using 6.0.1
Kind regards,
wifi reception and this issue is now fixed in the latest build. (.575)

Phone dialer delay/lag when hanging up

Been having this for a while now. When you come off a phone call, and I hang up via the red hang up button, it takes 4 to 6 th sometimes 8 seconds to actually hang up.
If the other party didn't hang up, they could hear everything I say even after I press the hang up button.
I have tried Google dialer and it's not there but stock dialer is needed for a lot of dual SIM functions.
Any advice please?
Maybe try clear cache of the app

Hi
I am having the same problem and just started looking for help. The only thing that stops this is a reboot of my phone. Gradually on a scale of calls made/received (not sure if it matters which), the length of time to hang up the call increases. When it gets to "painful" levels I restart the phone and it's nearly instantaneous again.
This is a bug in the stock LG dialer. Mine started after the latest Oreo update. Pre-update, I didn't notice any real issues.
This is driving me nuts as well. Has anyone found a fix for this? In my case even restart didn't fix it. The red hangup button is taking ages to respond and the call doesn't hangup until the other party hangs up
