Had my Sensation XE since Dec11 and it's been a great phone 90% of the time, no space issues or speed issues until the last few weeks, I keep getting messages coming up saying the phone is low on memory, first of all I went in and cleared the cache and cleared a huge 600mb from the cache and thought this may solve my issue. But after this I keep getting this message and the phone is running painfully slow sometimes. Currently of the 1.15GB internal storage available there is 435mb odd used and over 700mb free, so surely it cant be low on space. Each time I get this message I've been clearing the cache and theres only about 5-6mb in there. I'm not rooted or anything and I run go launcher ex. Any tips on how to solve this issue? Thanks.
