Q: iPhone 4S screen freezes after calls

I'm having the same problem on the iPhone 4s not sure if it's software or hardware but is very annoying .

Same issue...    3 times in 3 days....     Verizon 4S 64GB running IOS 501

Have rebooting the phone after each occurrance, p-roblem keeps returning.

Apple, is there a problem?

I'm having the same issue... Verizon 4S 32G. Seems to be a common theme..

Me too!! I just got my iphone less then 2 weeks ago.. it just started to happen within the last 2 days. After a call it just keeps saying call ending.... at first i would just keep restarting my phone.. but now i am just closing the app fully/airplane mode.. whats going on with it! ?

And... to make things worse.. my phone right now keeps switching networks..(from solo mobile to bell mobility)I don't understand why .. i can't even make phone calls anymore or receive any as of this morning.. help!

My daughter is seeing this on her new 4S and it is incredibly irritating. She is also having trouble with texts not going through and I don't know if this is related.

If you have a plastic screen guard / cover, you might try removing it. I had an issue with screen blanking which was caused by a screen cover. I've subsequently replaced the cover and voila, problem solved.

exact same issue...

My dads UNLOCKED iphone 4s, used for maybe a month, this happened 2ice alrdy

got the phone replaced and it happened again...

to top it all off my UNLOCKED Iphone 4 froze up while making calls 2ice also

both times i had to do a restore....

Symptoms are the exact same: Freezes up when making a call, the call goes through but the other party cant hear you speak, then when you try to end call it won;t clear the screen even if you press the top button and open it up again. Only way to get rid of it is quit the app at the bottom. But from that point on the phone will have the issue reoccur every time you try to make another call, oh and texts donlt work either

cmon apple this kind of stuff can;t be happening

super frustrating and annoying

Same problem here. My 4s froze after a call. stuck on "call ending". Had to do a hard reset. Lets hope it was a one off

yep, same here, as of last night. Nothing covering my phone, not a carrier issue. Done a hard reset and it didn't fix the issue. Any ideas?

same here, iphone 4s, 2 months old. was working fine until the 20th of december, after that it freezes while calling, can not hang up call, the call does not connect at all. also, it can not send sms, since it freezes when pushing the send button. tried restore, with the old backup and also with as a brand new phone, not using the backup, it did not help, the problem appeared again after a few days. hungary, T-mobile.

it is really frustrating, you are right.

As an update, we worked through Apple support and they eventually replaced the phone for free. I'll update here if we start seeing the same problem again.

My iPhone 4S also 2 months old began having the same problem. Had to do a full restore to fix it but problem came back 2 more times. I'm going to return the phone as it appears that this is the start of never ending problem.

My wife's iphone4S was also having this same problem. i tried restoring it into factory setting. phone works alright for some days and again the problem appears. i've done restoring for 2 times so i knew it was not the solution. so, this time i restored it into factory setting once again (for the 3rd time) and this time i didn't restore from backup. i started using it as a new iphone. since then i'm not having this problem. hopefully the freeze problem is solved. old backup was from 3gs so may be somethings not working properly if u restore from backup.

It seems that restoring it to the factory settings without restoring the backup really solves the problem, as for me it works now. The old backup here was from 3g, so I guess it was the backup.
