[Q] Tablet is acting strange
I've been using galaxy tab 8.9 with custom ROMs for more than a year and a half now, and sometimes it was acting strange, like flickering dialogs and crashes. Usually this meant an unstable ROM or just cache wasn't cleared when a new ROM was installed. And it was stable for some time, till I did a reset. Now no ROM is stable any more in addition to this, the battery sometimes says it is empty, but after restart it is back to normal status. I tried number of ROMs without luck, all are flickering lately which must mean it is not ROMs fault.
I am running out of ideas what to do with this tablet, so I'm asking if you guys have any suggestions, what else can I do to fix it.
NOTE: when installing a new ROM, I always did it with CWM recovery from internal storage with data, cache, dalvik wipe and factory reset.
