[Nexus 10 Q&A, Help & Troubleshooting] halrulez:
I have been having the same issues with my mic too. Really seems just like a bad design and placement. I was looking for some kind of app to some how boost the mic input, but there is none. I use a stereo Bluetooth for most of my needs but I always don't have it around. If you figure or anyone else does out any other type of fixes please post.
[Nexus 10 Q&A, Help & Troubleshooting] brooon:
Yeah, I'm begging for a solution, too. This is just a damned stupid bug - and the fact that neither Google nor Samsung feels responsible for it is just sad.
[Nexus 10 Q&A, Help & Troubleshooting] Injek:
We are in the same boat people. Maybe this could be resolved using custom kernels?

Could anyone please have a look into this? I'd be infinitely grateful!

Downgrade

I had this same horrible microphone quality in Skype problem with Lollipop 5.1 on my Nexus 10. A factory reset didn't help.

The answer: Downgrading to Kitkat 4.4.4 from the Android Developer's blog. Perfect microphone quality after that.

Not a great solution, but works until Lollipop is fixed.
[Nexus 4 Q&A, Help & Troubleshooting] DannyBiker:
So I was an early 10.2 adopter but I had to revert to 10.1 as restoring apps with Titanium BackUp wouldn't work with the new root method.

I'd like to know if the newer nightiles fixed the issue or should I wait for the Titanium BackUp app to fix it.

Thank you !
[Nexus 4 Q&A, Help & Troubleshooting] Rohit02:
You are the 10th guy I am replying this..

Possible fixes :

1) flash supersu v1.51 and enable the option for root app + adb

2) change the path of TB from emulated/0 to legacy

This will surely solve your problem. :)
[Nexus 4 Q&A, Help & Troubleshooting] DannyBiker:
Sorry if it was asked already...:o

So it looks it's a little bit of both. The solution seems fairly easy but I'll wait for the situation to be fixed on both parts to update...

Thanks !

PS : by the way, I'll be getting a N10 tonight...should I expect the same issue ? It doesn't look like it's device specific.

I have a lot of problem with Vodafone Italy configurating my Qtek 9090.

I used Vodafone setting, but i can't receive MMS.

It shows me that i have an MMS, it tells me to Download MMS, but no MMS is displayed, i think it can't download it even if no error messages are displayed!!!

On the other side.......when i send an MMS, it tells me that the MMS has not been send, but, i made a lot of tests!!!, the MMS is send and the receiver receives the same number of MMS that are showed on the "Try for.." setting.

Can you resolve my problem........Vodafone Italy's Operators aren't able!!!!

Please.........if you can write also in Italian to let me better understand!!!

Thanks!!!

Questi sono i settings che uso io. Devi naturalmente creare un profilo gprs prima. Considera che non è lo stesso per la navigazione internet (ha diversi settaggi) e che lo devi scegliere manualmente quando vuoi usare gli mms (oppure mettilo di default se non usi la navigazione )probabilmente non te li fa mandare ora perchè tenta di usare il profilo gprs configurato per internet invece di quello specifico. NB per poter ricevere mms devi almeno averne mandato uno prima .Ciao

[Sony Xperia ZL] schnidex:
I've just lost ALL of my calendar events.

My phone was not setup to automatically sync so I manually synced yesterday in order to back it up.

As it had been a while since the last time, Android told me that there were too many deleted items. I followed a fix I found online, (Settings > Applications > Manage Applications > All > Calendar Storage > Clear data) and then seconds later was prompted with a system message about deleting these items too, which I did.

I've now gone to my calendar on my phone, and ALL events are gone. Is it at all possible to restore my calendar? I use it for everything and will now miss important events if I can't get them back.

I've tried Spanning's Undelete but that only seems to work for individual, manually deleted items. Can I recover the cleared data in a similar way to undeleting a file on a PC?

2.There are two other hardware partition mmcblk0boot0 and mmcblk0boot1. When i open them with a hex editor, its just all zeros.

What is the purpose of these two partition?

Any help would greatly be appreciated. Thank you!

[LG Nitro HD] 6783:
I have found previous miui 3/6/7 (port) and used boot and etc from there. That's all what i have done. Maybe rom needs some fixes but i am running it for 3 hours without any problem. So if you find something wrong, please fix it.

And please write small FAQ what should i change when porting from su 640. I think it will help many of us. I have created thread in devel section.

You can disable it (freeze) if you don't use google services as google+ or google play (and maybe others). Those two ones require an active google services app.

With stock you can't. I referred to an app called shot control which allows you to, but when you set it to iso100 it usually freezes. About the lumia comparison, I think that these shots definitely are on par with the 920, which is pretty soft by itself. DDon't forget that XDA shrinks images, originals are much sharper. And about Nokia build quality, the lumias are definitely good, but traditionally Nokia had many flops: my 6120, N95, N85 and N97 all crumbled pretty fast.
