Firmware
The best firmware according to the members of the forum

Overview of firmware and recommendations from our members of the forum
Options for custom firmware.
1. CyanogenMod firmware (or CM for short)

CyanogenMod is pure Android without adding chips from the manufacturer, a huge team of people are working on creating the basis of these firmware. According to statistics all over the world, more than 4.8 million phones cost exactly CM firmware. CM firmware is usually focused on reliability and performance. You can read more
Here.
Video review.

2. Firmware based on stock.

The point of creating such firmware in increasing the performance of phones while retaining all the manufacturer's chips. And again, you get the opportunity to choose which software from the manufacturer to keep and which to remove. As a rule, only such firmware appears in the first months after the phone enters the market.

3. MIUI firmware.

MIUI is a highly modified android, sometimes reminiscent of iOS. Most of the MIUI firmware is based on CyanogenMod and is released almost immediately after the official release of it. The main task of MIUI is to simplify the management of the phone and at the same time add to the interface of beauty and the ability to change the appearance in the root. You can read moreHere. Video review.

4. Android Open Kang Project (or AOKP)

AOKP firmware is very similar to CM, however, it is considered that AOKP has more settings that change the phone's interface and some functionality. The AOKP development team is much smaller than the CM, but it often happens that a group of like-minded people gather to support the popular AOKP device with the AOKP firmware.

5. Android Open Source Project (or AOSP)

By and large, AOSP is a bare android. The way it is released by Google, most often in such firmware minimal interface changes. Often, the creators of the firmware indicate in the name of their firmware "based on AOSP", that is, at the heart of the firmware is a naked Android.

Where to look, what to change

Seen such a problem. I have three bodies, and they work differently with the same firmware. The drain all three work equally fine. 4.4.4 On the situation is different - one is working as de fine, the other two to reduce the radius of the reception a couple of meters. Apparently, different chips, and not all custom bikes have a full set of drivers. In general, if the radius of the smallest kastomov 4.4.4, you can try custom bikes based on the latest firmware sink should work fine.



Rep: (22)
Hello, what is now the firmware 4.4 shows better yourself? I consider the hyper rom or blekota, how are they?



Rep: (67)
Greetings ladies and gentlemen! Please tell me! Is there a firmware-based flow (eg light or scrubbing)?



Rep: (26)
* 19fox79 , Here too it is interesting



Rep: (38)
* 19fox79 As the man who sewed this smart phone, day and night, I can say that I came to the conclusion that it is better QS JB (you can read my post relating to this firmware: Samsung Galaxy S3 GT-I9300 - Informal firmware (OS 4.xx) (Post AxDemolution # 65344378) ) And Atila ROM-a ( https: //forum.xda-deve...-rom-gti-t3312992/amp/ ) there is nothing. This speaking of firmware-based flow. First - Android 4.3, the second - from the port 4.4.4 elder brother i9305. Stable is qs, a little less - Atila. But she has quite a few bugs have been, at the time when it is put. Therefore, as perfectly suitable on a permanent basis.
If no stock, then put CM11 - is a classic. It works quickly, smoothly, loudly.
All rom highly recommend core boeffla.
Well, just as the user Experience, I say that higher Lollipop firmware (5.1.1) already have a poor performance. But, again, there is already a new version based on the android 9 and 10, so I advise you to experiment, if you have time.

Now, in addition to screen Galaxy GI-9300 is nothing. The power button does not respond. When inserting the battery immediately starts and butlup. In rekaveri misses. When attempting to log a warning message appears in dounload-fashion with the offer to press Vol + to continue. Then again butlup. Where to dig now?

yes it is sewn. It was the same case with the other Samsung



Rep: (28)
all dobogo. guys for a long time did not come to the forum, but need made. lay the body of 2 years, it hung, was custom-based flow. made relief, came to life, but I need a phone to be used as a navigator in the car. revealed a poor reception dzhipies. Advise something lightweight with good reception.



Rep: (0)
Better flow in terms of reception gps did not come up with anything. When I'm at home, my unit on any firmware thinks is in the yard in a pair of tens of meters from the building, ie, may have devices in principle nevysokotochny gps regardless of the firmware. Try to play with the Google services that they are responsible for determining location. There is a firmware with a modified gps.conf by Russia (for example, thisSamsung Galaxy S3 GT-I9300 - Unofficial Firmware (OS 4.xx)), But I did not notice the difference.
