Guest fear_factory84 Posted May 3, 2011 Report Share Posted May 3, 2011 (edited) There is a long standing bug on acer's froyo roms with proximity sensor that drain battery after it's first usage. You can see the bug simply using an app that enables prox sensor, or do a call (android system process) and you will get a very high percentage on battery usage statistics. Normally this percentage would be decreased by the time, but since the acer libsensor has this bug, it will reach 99% of usage in a short time. Today I flashed lcr-e 1.8.2, and tested that proximity sensor worked well without this problem. Comparing libraries they were different: 4a7fc8e45e65f3b560ac194db7906ac6 ./system/lib/libsensor_yamaha.so 65495ab1045682b0246e2f119161a50e ./system/lib/hw/sensors.salsa.so flashed these libraries on top of fear_4.008.08.VFIT, and the bug disappeared!!! Yeah! Using z-devicetest app, all works correctly. Attached are zips to flash eclair libraries and froyo ones back if you have problems. Please tell me if they work or they have collateral effects. ps: it should work also on cm7_1.4.25_oldsensor.zip from koudelka, I have not tested it, but in theory since he used acer libs, it should work..fear_4.008.08.EMEA.VFIT_eclair_sensors.zipfear_4.008.08.EMEA.VFIT_froyo_sensors.zip Edited May 3, 2011 by fear_factory84 Link to comment Share on other sites More sharing options...
Guest mAdkoE Posted May 3, 2011 Report Share Posted May 3, 2011 (edited) Thanks man, going to flash it asap.Are in the zip the old libs or the bugged ones? Edited May 3, 2011 by mAdkoE Link to comment Share on other sites More sharing options...
Guest fear_factory84 Posted May 3, 2011 Report Share Posted May 3, 2011 Thanks man, going to flash it asap.Are in the zip the old libs or the bugged ones? _eclair zip are the old libraries that work, froyo ones are those who work bad, you can use them to return back.

Fear can we use this on 4.002.14 rom or it just works on ur VFIT rom's? and will this work along koud's 1.4.25? u think i should give it a try? thanks for your efforts appreciate it :mellow: Link to comment Share on other sites More sharing options...
Guest Lesheg Posted May 3, 2011 Report Share Posted May 3, 2011 fear_factory84 I compared by content your files and the same in LCR-F 2.0, they are completely identical. Link to comment Share on other sites More sharing options...
Guest fear_factory84 Posted May 3, 2011 Report Share Posted May 3, 2011 also works with your version of cm7? no, because it uses roggin's libsensor, if you use cm7_1.4.25_oldsensor you could use them.. (cm7_1.4.28_fear is the 1.4.25 build with roggin's libsensor and prox sensor disabled on kernel) Fear can we use this on 4.002.14 rom or it just works on ur VFIT rom's? and will this work along koud's 1.4.25? u think i should give it a try? thanks for your efforts appreciate it :mellow: it works on all the acer froyo roms. sensor libraries in 4.002.14 and 4.008.08 are identical. fear_factory84 I compared by content your files and the same in LCR-F 2.0, they are completely identical. files in the froyo zip are of course the one in lcr-f 2.0. That zip is made to restore them in case of problems. Link to comment Share on other sites More sharing options...
Guest Probie wan kenobi Posted May 3, 2011 Report Share Posted May 3, 2011 @fear_factory84 Noob question: Is this patch useful flashed on top of 4.008 stock BIN or it works well only on custom ROM? Anyway, i have just been flashed, going to test it. Thanks :mellow: Link to comment Share on other sites More sharing options...
Guest treyguitar Posted May 3, 2011 Report Share Posted May 3, 2011 Good job fear :o Flashed on t&l 4.002, sensor works will let you now if the bug arises again :mellow: Anyway, those libs are only for the prox sensor? Link to comment Share on other sites More sharing options...

Anyway, i have just been flashed, going to test it. Thanks :D there are no differences on stock roms regarding sensors libs. Good job fear :o Flashed on t&l 4.002, sensor works will let you now if the bug arises again :mellow: Anyway, those libs are only for the prox sensor? they are for all sensors, accelerometer, compass, magnetometer, light and proximity.

Guest sundawg Posted May 3, 2011 Report Share Posted May 3, 2011 (edited) Good job fear :D Flashed on t&l 4.002, sensor works will let you now if the bug arises again :mellow: Anyway, those libs are only for the prox sensor? yep this fix is for prox sensor..only ..its pulled up from lib's of eclair rom as they were stable .. :o oops my bad fear..as u mentioned in first post about prox sensor ..so my thoughts was about only for proxy..b.w great job...:D Edited May 3, 2011 by sundawg Link to comment Share on other sites More sharing options...
Guest treyguitar Posted May 5, 2011 Report Share Posted May 5, 2011 This seems to work fine for me! No more strange battery drain using proximity sensor!! hurray! Link to comment Share on other sites More sharing options...

Guest fear_factory84 Posted May 17, 2011 Report Share Posted May 17, 2011 Work They with CM7 thepasto kernel Andrea fix? you should have luck using those builds by koudelka called "oldsensors". they are in the discussion about cm7. Just replace libs on top of that. Link to comment Share on other sites More sharing options...
Guest GvM Posted October 16, 2011 Report Share Posted October 16, 2011 Hey, can u explain me just a bit. I have liquid s1 with froyo rom from liquid e unlocked for S1 (OS_Acer_4.002.14.EMEA.GEN1_Pass_A1). I then patched kernel with mt fix and swap support, this one. Then I noticed some nice drain after using phone a bit one day. Looked at ASI (android system info) and it showed me that proximity sensor usage was 75 mA. I found your patch and applied fear_4.008.08.EMEA.VFIT_eclair_sensors.zip from malez. Now ASI shows me proxymity sensor usage 76 mA. AM I DOIN RIGHT?
