Wifi and Cellular performance in the US?

I had a Mediapad X1 in the US and the Wifi seemed to be really bad. it was very picky about what Wifi access points it would connect to and when it did the performance was not that great.
The Cellular network (HSPA+) wasn't as bad but still had its issues too. Just seemed like the radio firmware for the US market wasn't really that good.

For you US folks, has the radio's in the X2 been working pretty well?

Cellular network (calls and sms) not working

Phone is rooted and unlocked with multirom since July and has been working great. 3 roms installed; liquidsmooth 5.1.1, chroma 5.1.1, and Ubuntu.

Yesterday, calling started to be intermittent. Sometimes switching airplane mode on/off fixed it, sometimes it didn't. Today I cannot get calls to work at all. Phone shows dialing but then hangs up before any ringing. Incoming calls don't work either, it goes straight to voicemail. I thought it may have been lollipop but the problem occurs in Ubuntu as well. Funny thing is that the phone finds the network carrier and has decent signal.

I havent changed anything on the phone recently, only thing is that I dropped it 3 days ago. Thankfully no cosmetic damage, but am starting to think internal damage.

I've tried soft reboot, cold booting, pulling the sim...no luck

Should also mention I'm on virgin mobile canada...
Any ideas?

WIFI and Cellular data on at the same time (Draining Battery)

So I got my note this past saturday and had seen how great the battery life should be. One of the first things I noticed on my phone was even when connected to WIFI the cellular icon showed up. After doing some research it appeared this was normal but should remain gray. This is where my issue comes in. On my device the cellular data icon is on and goes from white to gray. Sunday I ran the tools recommended in the Debloat thread. Yesterday I decided to test if this was draining my battery. So when I woke up yesterday before unplugging it from the charger I turned mobile data off ( the icon was on but had a / through it and remained gray.) When I left for work yesterday I enabled data, and again disabled it once at work and connected to WIFI. My battery life soared. I went from getting barely 10 hours of time to getting 25 hours available.

Today I enabled cell data and will be leaving it on all day. Im obviously not through the entire day as of yet but at this point with far less use so far I am running about 5 hours shorter then with it off.


So what gives? Is anyone else seeing this? I have already gone through and disabled all of the bloatware. I cant seem to figure out why cell data is staying on and being used. Here is a pic showing the data and WIFI being on at the same time. I am on a Verizon branded phone. https://goo.gl/photos/e8fNDeQ5ZaTAJ9gv8

How to fake a connected cellular network?

I have a Japanese carrier SIM-locked smartphone Fujitsu F-01F. The system software update is blocked since there is no carrier network connected.

I want to tamper this so it can let me download the OTA update. Do you guys know what is the component/service on the Android OS which the updating software use to get the current cellular network. If I know about that I can give it a try.

Summon @tewilove. Can you give an advice on this?

Whatsapp cellular connectivity issue

Anyone experiencing connectivity issue in Whatsapp while in cellular network? While app is running in foreground, there is no connectivity issue. But when it is in cellular network, incoming messages may or may not come; they will start to come once app is run in the foreground. There is no such issue when phone is connected to wifi. I have made sure background data is not turned off for Whatsapp (for cellular network) nor background data is restricted. There are no issue with viber, facebook messengers. I thought it was because I had my phone rooted. Recently I re-flashed stock and did not root but problem didn't go away.

U.S. Cellular

I'm planning on pre-ordering the phone very soon, but have one question: will it work in America? I'm going to Florida - for 2 weeks - in December and while the phone won't have any issues with cellular bands in UK, I'm not sure if this can be said in America.

Possible carries are Verizon, Sprint and T-Mobile. Can someone answer this for me, so I won't have to worry about getting a budget phone just for the trip there?

[FIRMWARE] Cellular radio reception FIX

Firmware for Cellular radio reception FIX

Warning
Flash at your own risk!
Check MD5 checksum before flashing!
To revert back, flash your RUU.

Introduction
I have two HTC Sensations, I found that one has a lot better reception than the other one.
The one that had better reception, I flashed a Sense 3.5 RUU beforehand.
The other one that had not so good reception, I had flashed a Sense 3.6 RUU beforehand.
Both had the 3.33 universal firmware from @Kohr-Ah installed.
I compared the firmwares from 3.33 and 3.12, I found that 3.12 has pg2fs_spcustom.img and 3.33 doesn't, I think @mike1986. removed it.
My conclusion is, pg2fs_spcustom.img must be different.
From what I know, pg2fs_spcustom.img has encrypted radio related code.
So I have repackaged the universal 3.33 firmware to include pg2fs_spcustom.img

Summary
After flashing this firmware on my HTC sensation with the one with poorer reception, I found that reception is now far better and faster to connect and switch between towers.
My results may differ from yours but I'm sharing this as it may be a solution for some.

Installation
Place PG51IMG.zip in the root directory of your sdcard.
Check the MD5 checksum is correct = 3abc6ae08031d3dd4c1820d2c2046c1a
Reboot device into bootloader and confirm flash.
Note: Remove PG51IMG.zip from root of sdcard afterwards.

Thanks
@Kohr-Ah for Universal 3.33 Firmware
@rmk40 for 3.12 Firmware
@mike1986. for Firmware Images

No data (cellular) on Straight talk with my LG G3(VZW) running Paranoid Android

Ok so I have Paranoid Android 4.4.4 and I had upgraded to the most recent (I believe 5.1) and no matter what I did or straight talk did, I couldn't find a solution to get the data to work. I ended up having to downgrade back to 4.4.4 to get data to work. Has anyone had this issue with this phone and lollipop on Straight talk? The best I can figure is that straight talk doesn't support Android Lollipop..can anyone confirm this or post a fix to this problem? Thank you guys.

no cellular data

HI,

I flash CM11(08/29) to my new fire phone. Everything works fine, except I could not use cellular data.
There is no error msg at all, but if I turn off wifi, I just lose internet.
I can make phone calls no problem. I can registered with ATT, and in LTE mode.

No issue with my SIM card, it works on my iphone 5s.
Do you thinks it is a hardware issue with my fire phone? which means if I covert the OS back to FireOS, still should expect the same cellular data issue?

THanks,
Lei
