Hi @puffs1 ,
You may have to take it apart to check that the second microphone (at the top of the phone) which is used when in loudspeaker mode has not been damaged by your repair. Also not sure but perhaps it is the same microphone for handsfree use when using BT
Hi @puffs1 ,
Firstly apologies. The upper (secondary) microphone is used for noise cancellation on calls not for voice transmission. Although it might be utilized more on speakerphone calls than on normal calls.
Was the loudspeaker feature working correctly before you repaired the LCD?
If so then perhaps if the upper mic is faulty it still might be the cause of a problem.
Here is a link that shows where the microphone is.
Here is a link to just one supplier of the part. It is not a recommendation to use them. It is shown to give an idea of the cost of the part.
I cannot find a setting (if there is one) that allows for noise cancellation to be turned off/on decreased/ increased etc. The only thing that I found was regarding HD on calls to improve quality. Perhaps you may find one. Check if there are any settings relating to speakerphone.
You could always try backing up your phone, then factory restoring it and then see if it works OK or not.
Be aware that a factory restore will erase all your data and downloaded apps. That is why it is important to do a backup first.
If it doesn't work OK, then it is a hardware fault.
If it does work OK in a factory default condition, then restore the phone from the backup you made and try it again.
If it still works OK then the reset fixed the problem.
If it doesn't work again after the restore then a downloaded app is the cause of the problem. The trick is to find out which one. You'll need to uninstall each downloaded app one by one and test the speakerphone function between each uninstall until it works correctly. When it does work correctly the last uninstalled app is the culprit.
