Regarding Custom ROMS

Hi there
Firstly.. No, this is not a typical noobie thread asking for the best custom ROM out there, as I know it's related to personal preference. My problem is that I have a download limit, so I can not test out every ROM I'd like to.
A solution to this problem would be if you guys could recommend a few of the fastest ROMs for me, in your experiences (I'm not so interested in eye candy, more usability.. and most importantly I want it AS SMOOOOOTH AS POSSIBLE, I love smoooothness ) After a few ROMs are recommended I'll have a better picture of what to check out and what to download and I won't be wasting toomuch of my download limit.
Thanks in advance
Why do you have a download limit? What is your limit?
I live in South Africa where not everyone has unlimited internet.. My download limit is 5gb a month (but thats for my whole family...) , but I'm pretty close to blowing it :-/
C'mon, can't anyone help me out here?

I think you should start a new thread (search first) entitled "Fastest Custom ROM?" That will get a discussion started, and people who are interested in the subject will see the title and post their opinions.
I'll try that.. I wanted to avoid that though, 'cause I didn't want this to be those typical "What is the best custom ROM?" threads, and recieve the typical reply of "There is no best custom ROM"

Just sort the forum by the ROM w/ the most posts or views. If you go with those they will most likely be the most tested, have more user support/solution, and they have gone through a couple different versions.

Yes, but the specific question is which is the FASTEST ROM.
I tried a couple roms and decided I hated 6.5, so I cannot say for sure...but I can point you in a direction to check threads...
Energy, Cell, Josh, and DeepShining have all had very positive responses, and speed is something commonly mentioned among the pluses.
I hope this helps. Perhaps reading those particular threads can help you decide before wasting bandwidth.

In other words it is literally impossible to tell. The fastest ROM will be a today screen or titanium with no mods, it really boils down to what you want your phone to do though. I personally like eye candy and stability, you can see what I've chosen below for those. Don't get me wrong, it is still pretty fast, just not as fast as a bone stock ROM would be. I'd be willing to download, burn, and send a DVD full of ROMs, let me know.

Sorry for taking so long to reply, I've reached my download limit lol.. I'm posting this from my phone's internet.
WOW! That DVD would be TRULY awesome, and I'd REALLY REALLY appreciate it. How can we go about doing this kind sir?
I have tested out LOADS of ROMs.
But I always go back to one in particular,
Touch X "SENSE 2.0B X-TREME"
Now unfortunately this ROM has been dis-continued.
But 2.0 is still available for download:
http://forum.xda-developers.com/showthread.php?t=575747
For speed its great. If I have no today plugin running when i soft reset, there's only 36% memory usage.
Manilla reaps the memory a bit, having around 50% memory usage after soft reset.
Which is why I use other today plugins like 'iphone today' and 'throttlelauncher'
Over all its the the best (in my personal opinion mind)
And its not littered with unnecessary apps

Can the Desire do 5.76mbps HSUPA?

I noticed that according to Qualcomm's press release
http://www.qualcomm.com/news/releas...first-chipset-solutions-break-gigahertz-barri
Snapdragon processor does 5.76mbps HSUPA by default.
The Desire is only set to Catagory 5 HSUPA which is 2mbps.
Can 5.76mbps be enabled???
I noticed in /system/build.prop you can change the HSDPA/HSUPA catagory settings
Samsung Galaxy S doesn't have Snapdragon, it has Hummingbird.
Just for information; made some tests with speedtest app on a cpl of servers, max download speed I could see was 4,6 mbit/s (my location Gothenburg/Swe, test server Aarhus/Denmark) and upload speed was appr 1 mbit/s, that was the highest speeds i hv reached by far. Hv no any clue abt technical details in terms of hsdpa, hsupa or whatever hw configuration built in my phone (Desire, network: 3 Sweden)

The Desire is only 2MB HSUPA capable. Honestly, that's massive uplink for a phone.

Sorry but my diamond1 and my old touch pro both have 7.2Mbit HSDPA, as does the desire. So 2Mbit is not that massive ever since 2006, yeah I had a TyTN too
We are talking about UPLOAD (7.2Mbit is download).

for starters the galaxy s has a hummingbird processor, thats an omap chip not an arm cpu like the snapdragon and 5 or 2 mbps unless you was sat directly under an empty cell tower that you had all to yourself you wont get anything ike that so it dosent matter lol
sorry my bad, lost my lenses
anyway is there a network with 5 mbit uplink, I'll be switching
I tought omap is texas instruments and they manufacture and modify arm cpu architecture, is that right?
I have 6.2Mbit DL and up-to 1.3Mbit upload here
Whoops... to clarify... I incorrectly mentioned the Galaxy S...
What I meant to say was, according to Qualcomm's own press release (see my revised post above)
"The QSD8250 supports HSPA data rates of up to 7.2 Mbps on the downlink and 5.76 on the uplink, with full backward compatibility"

OMAP is an ARM CPU, too. ARM is the underlying architecture.

Both the hummingbird and the Snapdragon are ARM7 instruction set processors.
If anything, the Hummingbird is an ARM CPU, and the Snapdragon is not, because the Hummingbird is based on the ARM Cortex A8 CPU core which is an ARM7 processor, and the Snapdragon is a custom implementation of the ARM7 instruction set - it i not based on the Cortex A8 core, but does use the same instruction set.

Motorola Photon Q 4G LTE Comparison

Finally an upgrade path for Epic 4G users and/or Tactile fans. Everything else was a downgrade.
The Motorola Photon Q 4GLTE (MoPhoQ) appears to beat the Epic 4G, in all accounts, hands down, at least on paper.
The MoPhoQ has every option that the epic has except possibly touchwiz.
The only items I am unsure of are the Processor and Battery Life.
The Photon Q meets or exceeds all the specs & features of the Epic 4G.
Radio: Full world phone with 4GLTE & CDMA 800, CDMA 850, CDMA 1900, GSM 850, GSM 900, GSM 1800, GSM 1900, LTE 1900, WCDMA 850, WCDMA 1900, WCDMA 2100 vs. E4G- obsolete
WiMAX 2500 with CDMA 850 & CDMA 1900
Battery Size: 1785 mAh vs. 1500 mAh
Display Type & Resolution: LCD 540 x 960 pixels vs. OLED (Full-Color) 480 x 800 pixels
Display Size: 4.3" vs. E4G- 4.0"
OS: Android ICS 4.04 vs. Android 2.36 unless rooted
OS updates: Highly likely for the Photon to recieve JB as it is newer and a half-brother to Android by marriage.
Memory, Internal Storage: 8 GB raw hardware, 4.6 MB available to user +1GB RAM vs. E4g- 1.5GB raw hardware 461 MB available to user
Camera: 8+ megapixel vs. E4G- 5+ megapixel
Video Capture: 1080p HD 30FPS back & 720P front vs. E4G- 720p HD 30FPS back
Also the MoPhoQ has TV output via HDMI port, 4G LTE, Hearing aid compatiblity, NFC, it's not samsung & it has 4G LTE.
The only down side is it weighs 15Grams more and is several thousanths on an inch larger, literally 0.070" larger.
Now my questions are about the processor and battery life.
Processor 1.5 GHz Qualcomm Snapdragon vs. E4G- 1 GHz Cortex A8 Hummingbird
How much faster, better, more efficient etc. is the processor?
Does anyone have any ideas on the expected battery life of the photon?
The published battery life information appears to indicate a +25% increase in battery life

much faster and more battery efficient. It is based on ARM Cortex A15 architecture, whereas ours is ARM Cortex A8. Also, it is dual core, whereas ours is single core. Both of these qualities make it better in both ways. It also has a radio integrated into the processor, which means it saves power since it doesnt need to power multiple things for Radio. The dual core S4 processor of the Photon Q is faster and more battery efficient than the quad core processors on the market due to its newer architecture (S4=A15, current QuadCores are A9). If 2 A15 cores are faster than 4 A9 cores, then it would have to obliterate 1 A8 core.
Not sure about battery life specifically. It should be about on par with the AT&T One X

Buy SGS4 now or wait for S5 in April??

I've been researching the two devices but could still use advice. Here's what I've come up with so far:
SGS4
5.4 x 2.7 x 0.30 inches
4.6 ounces
Android 4.2 (Jelly Bean)
up to 15.5 hours talk time
up to 18 days standby time
13MP Camera with 1080p HD Recording
2GB RAM, 16GB ROM
Sync methods: Bluetooth, WiFi, USB, NFC
4G Capable
Wi-Fi Calling
Audio and Multimedia
T-Mobile TV
GPS and Apps
GPS enabled
International
UMTS: Band I (2100);UMTS/HSPA+: AWS Band IV / 2100 / 1900 / 850;Band II (1900);Quad Band GSM;LTE
Hearing Aid Compatibility
M3
Size and Weight
5.59 x 2.85 x 0.32 inches
5.11 ounces
Android 4.4.2 (Kit Kat)
2.5GHz Quad core application processor
16 MP Camera
2GB RAM, 16GB ROM, 128GB Expandable Memory Slot
Sync methods: Bluetooth, WiFi, USB,LTE
4G Capable
4G LTE Capable
Wi-Fi and Mobile Calling
T-Mobile TV
GPS and Apps
GPS enabled
International
UMTS: Band V (850);UMTS/HSPA+: AWS Band IV / 2100 / 1900 / 850;Band II (1900);Quad Band GSM;LTE
Looks like the big differences are the processor (is it same just overclocked or new hardware?), the camera (+ 3MP), heartrate sensor.
Does the S4 also have the expandable memory slot and dual wifi/4g data transfer? I want a phone I can root but I don't want to invest in something that will be quickly outdated...

Unstable/Lag LTE Issue

Hi, I have the S20+ purchase from carrier here in Canada. When I play online game or video conference from time there is connection dropping for 1 or 2 second sometime up 5 second. Its very frustrating during gaming. My 3yrs old LG never had this problem, my signal is always 1 bar away from full.
Setting on LTE/WCDMA/GSM and 5G is off as my carrier doesn't support 5G yet.
I read on the samsung forum many people had worst problem with early firmware. Does anyone know any idea can help improve this problem. I did a Network settings reset didn't help.
Hello,
You can try forcing only low bands or only high bands. You must remember to change back this setting if you want faster speeds or more coverage. The low bands will typically help with stability and the high bands will typically help with speed.
*#2263#
You should see band selection. Choose clear all. Choose WCDMA 850, LTE 5, 12, LTE 13 and save.
If you mess it up, press clear all then select all and save. It will set your phone back to the original band selection.
I get almost the same here on Sprint in America. I see connection drops (while still connected) and some data slowdown.
It happened on my s9 plus so I just knew to reboot. I think it's more carrier end then phone, unless it's just Samsung in general

Thank you this been working for the last 10min testing. I had to say on the speed test before I am getting 200-250mbps/sec on download now at 15mbps. It be nice I can get it to around 50mbps .
@creep138 I had Iphone, Asus, Sony and LG never had this problem. Yes, Samsung speed test is a lot faster but I rather have a stable connection than faster.

You're welcome. You can choose to include band 2 or 7, depending on your carrier. But it will kind of negate the reason for choosing lower, more reliable bands in the first place. Good luck!

I google my carrier LTE bands and did some testing.
700 MHz Band 12, 13, 17, 29
850 MHz Band 5
1700/2100 MHz Band 4
1900 MHz Band 2
2600 MHz Band 7
7 is is not stable and 2 is much more stable and good speed over 100mbps.
