Problem with ram managment only 200mb free with nothing inside i did the update 2 times with SUS, Is there a way official to come back to 4.1? My phone lags. Iam very dissapointed sony has a big problem with her updates. Iam not going to buy again phone from sony i had xperia ion again problems with the update.
4.3 is supposed to use more RAM,so from 1 GB that SP has,you will not get too much free.Force close apps you do not use,it will help.Also,restart the phone often.
This is strange...in any case you will have around 300 (+ / -) free if you are not running too much apps especially with no app, as you have suggested!
After update I got only 180mg free ram.but after factory reset by phone problem fixed...now I have viber.whatsapp.instagram and illustration bar and fb that running. In background. And I have about 300mg free
my uncle is using xperia sp and he is also having the same problem. He is also having problem of lag. He went for factory reset and now his phone is better than before. As far as RAM matter is considered, android 4.3 require min ram of 1gb and recommended ram is 2gb as said by google. This 4.3 rom is actually designed for xperia z and z1 they have 2gb of ram. So one thing is clear that you cannot solve the ram issue. Normally you will be having 250 to 300 mb free ram. In 4.1.2 phone was supposed to have at leat 450 to 500 mb of ram because 4.1.2 recommended ram was 1gb. And idk about rollback of OS.
