Hi. I have a Sony Xperia Z3 Compact. One month ago it got some problems, I think all at the same time. Is it malware or something else? 1) Before my background was blue. Now it is black. But I am not really sure about this point, I could remember wrong. I also got an analog watch showing when the phone is locked. Never seen it before (for sure). 2) Above my camera icon I had my photos (showing the last one taken). I could tap it and access them, or swipe through them. Now I only have my photo icon. To access my photos, I must now tap that icon (getting ready for a photo), and then tap on the photos afterwards. 3) Several apps have disappeared. Colornote, Snapchat and more. Some are still there, though. However, I do find all all apps in Settings-Programmes. But I can not access them, only uninstall and clear caches (and more). 4) I can't access Google Play anymore. "Google Play Services has stopped", I am being told three times when I unlock my phone. I also got the message "Error: You haven't accessed the Google Play Store app on your device with this email account". Well, I know I have. This is what I have done: Cleared cache and uninstalled updates in Google Play Services. I have also made sure I use the same Google account on my mobile and pc. Whatever account I try on my mobile, it does not work. My new situation: I can't open several of my other apps, like Skype. It says I must update my Google Play Services (as said, I uninstalled the updates). I am offered to update it, and push "yes". Then I get a fail message, obviously because Google Play Services is not working. I also planned to download a malware/virus scan program (360 Security, adding to my AVG), but I can't use Google Play Store either. So I am kind of trapped in this problem. My screen had a problem, that it loosened from the phone itself (I had it changed last year). This happened around the same time, or they rather started some time before. I have had my phone for repair, and they fixed the screen. I underrated my other problems, and should of course have asked about that too. Do I need to factory reset everything? It would be nice to reach my apps first, like my written notes from Colornote. Could it be malware/virus, that may still be there after the factory reset? This is of course frustrating, and after reading and trying to fix it, I still have the problem. What do I do?? Thanks in advance for any help.
