[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] BeeJ1109:
Hi,

I have a Samsung S3 i9305T version. For years I used the latest Stock Firmware. Being I9305TDVEOK1 for Baseband version, I9305TDVSEQA1 for Bootloader version, GT-I9305OKJTEL for CSC . Build Fingerprint samsung/m3xx/m3:KTU84P/I9305XXUFBB1:user/realease-keys.

On Stock ALL functions worked perfectly with No issues, except Android version 4.4.4 started to prevent certain apps to update or function at all. So I upgraded to latest version of RR-N-V5.8.5-20190219-i9305_rodman01. with Kernel boeffla-5-lineage_14.1 with Bootloader, Baseband, CSC, Build number same as Stock and listed above.

Most functions are working perfectly with this version of 7.1.2 FIRMWARE, TWRP is 3.0.1.2. as later versions tried but all had issues, bootloops, random restarts etc. Using Magisk Manager 7.3.2 with Magisk 19.3. Safety net passed as well. 130 apps downloaded via Google PlayStore. No issues and all Apps latest updated to date.

Problems I am seeing.

1. High Battery comsumption, Fully Charged Battery 100% discharged to 0% in less than 24 hours. Charge and discharge pattern same with 3 new batteries, or 6 year old batteries. Being substituted and phone left on idle, no calls, Left in Airplane mode, therefore No mobile network, no WIFI, no Bluetooth.

Using a battery monitoring software, Gsam.labs Battery Monitor Pro V3.37 (latest). Being testing now for months since updating the Rodman's RR 2019 release. Needs some research to fix the Kernel is listed each time as the highest consumer of power. [MENTION=6983722]42.[/MENTION]8%, Google 6.3%, Google Play Services 6%, OS System 3.4%, Total App usage 89%, Wakelocks, 8%, Screen 3%.

So clearly the power usage is the Boeffla KERNEL, which is included with Rodman's RR 5.8.5 2019 version. No modifications just installed as downloaded.

2. MHL doesnot work on this firmware, worked perfectly on Stock 4.4.4 firmware.

Using 11 pin MicroUSB Samsung Compatiable HDMI convertor. with its own USB power lead.

This device will charge the phone battery as well as MHL electronics.

But HDMI convertor is not recognized by firmware.

On bootup with HDMI powered with standard charger, and charging phone as indicated by bargraph symbol on screen updating as well as % of charge increasing over time. Up to 100% if left for a few hours.

Exactly same as using standard charging lead.

Whilst the HDMI convertor is charging phone, then switch phone on to bootup, RR icons will work for a short time then lockup and not complete bootup as normal. Sometimes may reset back to bargraph charge symbol. If Phone has fully booted with Home screen ready for use, then plugin MHL item. Normal on stock firmware HDMI will be connected and be fully function. RR Firmware will lockup phone and normal restart the phone back to charging bargraph symbol.

Therefore this RR firmware has drivers missing and therefore HDMI or MHL is not operational.

3. During testing NFC function, which can be enabled or disabled via software switch is indicating OFF or ON. Also listed as a working function in Phone INFO Apps.

Tested using several batteries that work perfectly in Stock firmware or other Samsung phones S4 i9195T.

Working in S3 i9305T stock, but not in Rodman's firmware.

Any comments or fixes to these 3 issues would be appreciated.

Phone with this firmware works perfectly in all functions except for 3 issues.

Tried a few other versions Lineage OS , but most had many more issues, WIFI, SIM not recognised, bootloops, work for awhile then lockup or reboot etc.

So Good Work on this phone's RR firmware. Great job.
