Data dropping when starting video calls - Verizon HTC 10 Questions & Answers

Weird issue here. I've noticed that when I make video calls with Duo or Facebook Messenger, the calls rarely connect or drop immediately. Then my phone requires an airplane mode flip for data service to kick back in. Anyone else with this phone havinf this issue?

Phone connection issues

I've flashed my phone with the latest firmware from the HTC site. It's connected to 02 but i'm having major problems with data connections and actually just getting the phone to answer calls.
If I ring the phone, the majority of the time it just goes straight to voicemail but sometimes the phone will ring, it seems to be very random. Data connection is iffy as well where sometimes i'm able to browse sites and other times it just errors.
Has anyone experienced this? Is it a phone configuration problem or is my handset faulty? It does get very warm at the bottom of it when the screen is on. Is that normal?
cheers

I think I have similar problems.
I've noticed a slight increase in calls redirected to voicemail.
Also, my HD keeps dropping data connections. Sometimes I can just reconnect using the settings tab, but sometimes a soft reset is neccessary.
Very irritating, and I was really hoping for a quick fix.

Dropping calls when switching from EDGE to GPRS

I was wondering if anyone else was running into something like this.
I have a T-Mo band N1 with AT&T service so I max out at EDGE, but something strange happens when I'm calling people from my house. Sometimes the other person will just stop hearing me but I can still hear them, it seems to fix itself after a random amount of time but sometimes it doesn't. But before the two way connection is reestablished one party has usually ended the call.
The strange part is when the call is ended I see that my connection has switched over to GPRS and after a few seconds it will switch back to EDGE. I assume that the switch from EDGE to GPRS during the call and that's when the other person can no longer hear me. When I start the call I have 3 or 4 bars on EDGE so I don't know why my N1 would switch to GPRS during the call.
This doesn't happen when I'm outside, but this happens when I'm not wandering around my house so the signal should be pretty stable. It has happened whether I'm holding my phone in my hand or it's sitting on my table with the speaker activated. There have also been times when I've spent an hour or two on the phone at home without this happening at all.
Anyone else having this problem or have any idea what may be causing this?
actually i notice my data connections disconnect like if i am downloading or uploading or connecting to something and i switch between H-3G-E i lose the connections. i didnt put much thought into it but i guess its -1 for me.

Missing calls

I've read a few similar threads and it seems that many people have noticed the same but haven't seen any real solution.
I noticed that when I try to call my phone, the 1st attempt will be missed (it will either redirect to voicebox due to unavailability or it will ring as disconnected and never get notified). The 2nd attempt will ring ok.
I haven't seen anything helpful except from turning 3g off but I have it on auto and use the mobile widget which I assume does the same.
Anyone noticed the same? it's worth to try it though because you may have the same and be unaware of it. (Try to ring your phone when its in standby and hasn't been used for several minutes)
I bought the DHD yesterday, in the few hours i used it i didn't notice the issue you describe. Just to be sure i called my phone a minute ago and i had no problem.
I have 3G turned off and i'm not using voicebox (using missed call alert instead).
i have a feeling its because if you turn the phone over it rejects the call. i keep doing this because my phone is in a slip case all the time. anyone know how to turn it off?

No, it doesn't . It just mutes the sound but if it's already turned over when it receives a call, it will ring. You can change this behaviour in settings-call as well as volume control for flip case.
I tried several more times and it doesn't happen now. It just happened a few times when I tried to test. The only setting I changed now was for GSM-3G not to force 3G connection on for all the time. Maybe that helped but now I'll have to see how my data connection is affected.

Yesterday whilst in town, a friend said he had tried to get me several times, only to get a network message that the phone was unavailable. seems fine each time i test it though, and there is a strong 3g signal around here. I put it down to everyone in town christmas shopping and net network cell being clogged up with people calling each other to find out where there other half is lol.
What network are you on? I'm on Orange, and get this all the time. It seems to be when I'm in an area where there's only gprs which cannot work with voice calls simultaneously. For some reason the data signal is given priority and the voice call is rejected. Surely it should be the other way round? Not sure if this is a network problem or a software problem... if the latter, is it HTC or Android?

Calls going silent

I have been experiencing this problem with making some phone calls where it connects to the line I am calling, but it goes silent. They can hear me, but I can't hear them. I have found that it usually depends on who you are calling. I just did a test with a friend's cell phone and a land line. I called the land line 10 times in a row and there is never a problem. But when calling my friend's cell phone, it is random. Would go silent the first time, then be ok the next 2 times, then silent again, and so forth. Also, my friend's cell phone is set so that it only rings one time, and then the voice mail picks up. I know this from looking at the top right of the phone screen where it says "Dialing", and when the call connects, you will see a time counter. When the time counter is running, it is still silent.
I wiped the phone app cache and system caches, but the problem still occurs.
Any ideas why this is happening?

Similar issue here....I use the Ice View case....do you? I go in and out of silence with people all the time.
No, but I'm not sure how the case would have anything to do with it

well considering I get weird behavior from the case all the time (25% of the time wont show music controls on double tap when music is playing, occasionally doesn't pick up or hang up on swipe)....I think its quite possible it could affect call quality/mic volume if it can exhibit these odd/wrong behaviors as much as it does.

Intermittent no in-call sound on incoming calls

Hi all,
I have a bone stock Moto G4 running Marshmallow and have been experiencing an intermittent problem when receiving calls, where neither I nor the caller can be heard. It's as if both of us have our mute buttons on, or as if neither of our speakers is working. The phone rings audibly and the call is logged correctly when I answer it, so evidently the call is "going through". All other sounds play normally; only in-call sound is affected.
When this happens, if I immediately call the person who called me, the call goes through and we can each hear each other fine; i.e., the problem only occurs intermittently on inbound calls.
If I reboot the phone, the problem goes away but eventually comes back.
I've seen numerous reports of "no sound during calls" posted here and elsewhere but most of the posts I've seen are pretty old, and don't seem to apply to my phone.
I posted this question over on the Lenovo site but I haven't gotten any responses so I thought I might also check with the experts here.
Thank you for any help.
Inbound Intermittent Call Ring
Hi,
I have a Zenfone 3 Max ZC520TL, with Android Nougat and the latest firmware (14.14.1808.121) running on T-Mobile network...
For the longest time I've had an issue with incoming calls most of the time going directly to voicemail, no matter how many bars I have...
I've been researching this for sometime now and most blogs (after they recommend advice on fixing the issue), want you as a final resort to do a backup and perform a Factory Reset...which people say didn't work, so that's wasted time...
I have an extremely easy fix for this which will take you about 30 seconds...
All you have to do is change your 'Preferred network type' from 4G to 2G...you can do this by going to: Settings/More/Cellular networks/Preferred network type...tap Preferred network type and choose 2G...that's it!!! Your phone will now ring every time there's an incoming call unless the number is blocked...
By choosing 2G, you may lessen the internet download, upload, movie and video watching speed and image download speed in texts but increase the signal range...I personally am willing to give up image in text speed to receive incoming calls with no issues...
If you want to download or upload or watch movies and videos from the internet or download images in texts instantly, just change the 2G setting back to 4G temporarily...
I hope this post helps and saves others from spending hours looking for a fix for this issue.
Cheers,
Vinny
