I have a Sony Xperia sola in Egypt. I bought it with Gingerbread, then I upgraded to ICS 4.0.4. After the upgrade, I became unable to download any apps from Google Play using my mobile network, and while using Wi-Fi the download is slower than before the upgrade.
I tried all available solutions like clearing cache or clearing data from Google Play or Google Services Framework, in Settings -> Apps -> All. How can I fix this problem? As it is very serious, many times I'm at places without Wi-fi and I need to download a missing app, or upgrade another one.
