[Nexus 4 Q&A, Help & Troubleshooting] met4ller:
Hi, finally here I am with my new Nexus 4. Through different devices that i disliked (like Acer LM, Nexus S in part), now I see a very good phone that does like everything. So here I wanna clear all my (and ours) main doubts regarding settings or tools that improves it. I red a lot in this and in a great italian forum, but some matter isn' t totally understood by people so informations may be subjectives and not in the same way.

So let's start :)

1- in the beginning of my history with android, 4 years ago, I thougt that 3g data with a good company works perfect with normal settings. But since 2 years I'm using a good and necessary app, Rom Toolbox. It also backup apps, but here it's important the set DNS function. In the past I saw improovements tapping Google DNS, internet was fast, but now, for example, using google search, it takes 2-3 seconds for showing results.

Why this "connection freezing"? Maybe other settings may be helpful for connection ?

ex."auto apply wifi/mobile network tapped, or improove dwd speed in some way...

2- A) I see that some rom users has wonderful battery experience. I would like me too :p, so I tried CodeFire X + matr1x 7.5 .

It has 10 days of life, but I would like to set everything, so : I need to do the undervolt fix, in addiction to the matr1x kernel (probably already undervolted), or this isn' t necessary?

Do you think that exists better ROMs regarding fluidity/battery improovements? Here I have 0 lag, for now (with a lot of apps installed with no notifications drains).

But I'm not very happy regarding battery: 2hours 22minutes, now 79% with 38% screen (46min), 32% phone calls (18min), 6% android and 4% firefox, connected with 3g (low use).

B) I tried Easy battery saver, i'm so uncertain regarding this kind of apps, because users opinion is so differents, like the choice (EBS, JD,2xB, Green Power). I choice this one only for download and stars rating.

But also Snapdragon may be good. For now, i found on them the lolzful situations: people that talks about 24 hours improovment(!!!) and a lot of people that is very happy, but on the other side others that says that process drains a lot of battery.

I think, at the end, that probably one of this apps may be good for battery, and you? If yes, I can't understand the best one.

3- A) android assistant: I can't understand if the "clear process" widget really free RAM or not. In the past I also red that task killing isn't good for android, but freeing RAM may be good (if apps are really closed, and don't re-open after memory release).

on nexus s I loved to close all processes with it's icon on the bottom of the screen. Now isn' t included (stock included, dunno why), so I can use Android Assistant as substitute?

B) boot assistant on AA really closes all app that i tap? I have everything blocked, like 10-15 processes ,unless sms and 2 widget.

4- I passed 4 hours for understand that dolphin can't import firefox bookmarks, it can't see folders. So I tried FF for android and now oviously they sync and passed everything. But I can't understand how to set FF bookmarks widget, no apps or ways to do it. If not, it's also perfect having a FF bookmarks shortcut ;)

I red about a way to pass them on stock browser, ok , but after I can see on the stock widget all my folders and bookmarks inside?

5- FastGPS is always useful for improoving GPS signal?
