Maximise Signal Strength - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hi All
I'm running CM10.3 with no issues apart from my signal strength doesn't seem to as good as the stock firmware. Is there any modem flashing i can do to sort out the issue please?

Cm 10.3? 4.4 released already

I have no experience of the stock rom as I installed CM immediately after buying the phone. However, I also experience poor signal strength. My signal strength is most often at 1 or 2 bars while I had full reception most of the time with my old Motorola Defy (with CM). Stand by battery capacity is significantly worse than my old phone with a 3 year old, much smaller battery.
I'm using 20130908 nightly and I9195XXUAMH1 (lastest) baseband. I'm going to get the latest nightly and experiment a little with older baseband versions and see if it gets better. Might also try the stock rom for comparision.

Weak wifi signal

I have an extremely weak wifi signal, I am only next door (About 1 meter away thru wall) - my laptop, nokia N95, PS3, nokia N97 and iPod have full bars but my phone has only 1.
My HTC Desire has a very low signal and often drops, when it drops I have to disable wifi and re-enable wifi else when its re-scanning it will never find the network.
This problem only occurs when using custom ROM (Currently using MIUI), I've concluded this by installing MIUI, Oxygen, GingerVillian and stock htc. Only in the stock HTC do I get full bars.
I have tested on all with recommended radios and stock radio. HTC ROM has full bars and never drops on all radios but the other ROMs have extremely weak signals even when using the recommended one.
Please help!
Noting the lack of replies on this issue, I'm only guessing that there is no real solution.
I also have found out that I must be on the wifi setting page for my phone to auto re-connect.
hi SMCentral,
found your thread while searching for weak signal cause.
feeding back to your test with different roms, i am on a stock rom (sw 2.29.405.5).
my wifi signal strength was very good last year as far as i remember, but recently suffering from very weak reception. i suspect a bad radio update over OTA. so different stock rom might differ. now i also have to go to wifi page to reconnect probably the signal seems too weak.

PS: Baseband version is 32.49.00.32U_5.11.05.27
hope this helps someone to find the cause.
There is an update for the radio here (5.14.05.17). I downloaded the second file since it said it was safer to use. For me it's stable and nothing really happened but people are saying it has improved reception/signal.

I don't have problem with my signals whilst using stock rom but if I use a custom rom with any radio baseband and RIL, I get a very weak wifi signal. Try flashing the latest radio from http://www.mightyrom.com/mrx/MRX/Bravo/Radio/Signed/32.49.00.32U_5.11.05.27.zip

I'll be trying this. Will feedback with results. Thanks buddy.
No issue for me regarding signal strength....
On a side note: I wish HTC had incorporated the wirless 802.11n standard to their WiFi module in the Desire...that has a far superior range and better bandwidth.
Yeah, if it had n support, it would of been amazing. Totally amazing.

Yup and would have stopped them selling more desire HD's with n capability. Sure it would have been nice if they had included it but that's life in the mobile phone marketing biz
No wait, after some research. HTC has hidden n capability. :O
I've flashed the .zip and well.. it works signal has become stronger too.
Just flashed the new radio , getting mmuc better wifi signal strength
Thankyou xD
You serious? They actually hid it??....that's so fiendish!!

[PRO] my phone loses data signal easier. Flashing basebands help?

so... It seems that at my workplace, and which is worse, exactly at my booth, I started to lose signal very easy... it's as if the phone kind of detects that signal is is weak and feels lazy to be decoding that and just stops, it's like it gives up easier.
It used to work fine, always had decent signal and no problems at all.
So, I was wondering if flashing Basebands could help on this.
Also I am not quite sure this if this issue started happening on a new ROM I flashed, I honestly don't know. You think it could be related to a ROM, considering I am on stock kernel (locked bootloader)?
IMHO, it is more of ROM problem. Flashing baseband does not affect the signal strength significantly. Check with ROM dev if there is problem with signal strength.

You could try different basebands, the higher number doesn't necessarily mean you'll get better signal
However make sure you flash libs
Libs?... what libs?

[Q] Stock Rom/ CM help

I rooted my Sprint Galaxy S3 to CM recently I update to 10.1.1, I noticed that my Signal has dropped dramatically many say because CM can't get the PRL needed because has something special (something I didn't understand) Is it possible for me to do anything to raise my signal strength? p]or would I have to flash stock rom and if I have to can i flash stock rom without losing my root?
CM or AOSP roms for that matter read a truer signal strength. TW roms have a different reading of signal strength. You can almost say they round up. You may still have the exact same signal it's just the reading and reporting which is different.

[Q] One more radio/signal question

My question is about signal strength and/or radio differences among different ROMs.
My EUR G3 is rooted but otherwise stock with 10L. It works almost perfectly for my needs.
Titanium Backup, Greenify, SuperSU, Xposed modules and Nova Prime have delivered a supreme experience so far.
The only thing that worries me is signal strength.
From the beginning (back in July) the signal (all bands) wasn't as strong as I expected to be. At some point I realized that I loose a few calls and then I called Vodafone which acknowledged the problem and provide me a microcell - which has done a terrific job for two rooms in my apartment but not so for the one room away from the device. Needless to say that the battery performs just great cause the G3 has not have to search for a better signal all the time. Outside things are far from perfect: in some places I have very good signal while at others a very bad one. And here comes the question: is there a custom ROM in kitkat or lollipop offering a better radio/signal?
The reason I haven't tested yet is because after a last week's flash I went back to stock with kdz and started from scratch in order to replicate the very good experience: long lasting batter, great SOT, no lag etc while checking the radio performance. Everything is fine once again except the latter. I really don't want to send my G3 to service and risk the current setup & performance and that is why I wonder if I should try some particular ROM or any other available solution.
Any suggestion for a ROM with better signal strength?

which firmware best reception?

Hi all,
I have firmware NF2 as base, with Vanir Kitkat flashed on top of a reparted file system.
All works fine, but one thing I noticed.
Reception is not so good. While other phones have reception, this phone often doesn't.
I have the feeling reception went worse when I upgraded to the last official NF2.
I can't really compare as I have only 1 Ace 2, but how is your experience with this?
Did you notice changing firmware and baseband that reception went better or worse?
Which firmware do you guys advise which gives a good reception?
