Its digitizer defect. It happens to one of my client before. Guess its common problem for i5.

If you have the vibrate function turned on, turning off the ringer will cause the phone to vibrate when calls come in. If vibrate is turned off, the phone will simply stay silent if a call comes in.

Since you have warranty still, you can opt for a warranty claim. thats the best option.
Suspecting docking problem.

The solution is to change the i2g battery. Prolly battery bulged and pushes the screen up.

Dock connector is the main thing to look into. Try changing this first.

Hi,

You are not alone, there was a guy who faced this problem yesterday with yuziq.
Put your iPhone into DFU mode and click restore.

Hi,

Many people are facing the same problem. Best is wait for next software update so can fix this issue. Nevertheless try restoring your iPhone first.

Yeap, suspecting wifi ic.

If its fixable then its around 400-600.

Don't think is feasible. Will not possible to separate the glass man.

Problem is with the headjack assembly. It has got few functions, power button, volume button, headjack, and mute. Either 1 KO, will need to replace all at once.
Rough price 100-400, depending where you get it fixed.

It's not worth to change back cover now. Its close to half price of a new iPhone lol. IF you manage to get those cheap grades quality also cost you few hundreds at least.
Suggestion to you is to wear something to cover up.

Since its under warranty is better send in for a new one. The only drawdown is getting a refurbished set instead of a new one.

Its common for may people after updating the software. Nothing can be done for wifi problem with software. The only solution is by changing the wifi chip.
Nevertheless, you can wait for the next softwre update. Might able to solve your problem.

This is depending on your luck. Most prolly latest IOS.

You are saying the other party cannot hear your husband voice during call?

its due to audio IC problem. This happens during GSM call only. Most prolly impact from droppage.
For a permanent solution is by changing this chip ya.

Process will take say at least for a day for chip changing. Cost for IC chip is above RM200. Those below RM200 sure is by adding in jumper only which cannot last long.
*Subjective to where you get it fixed

Do a fresh restore see if it works. Try joining other network

You will need to change "4s headjack assembly" it just looks the same as picture below. Covering earphone jack, volume & mute switch.


Price is depending where you get it fixed. Usually below RM200.

Try changing full front assembly if common troubleshooting is not working. If you know then unplug the cables and reposition it. Give a test.
